Background Information [Abstract] | |
Nature of Operations [Text Block] | Background Information The Federal Home Loan Bank of Dallas (the “Bank”), a federally chartered corporation, is one of 11 district Federal Home Loan Banks (each individually a “FHLBank” and collectively the “FHLBanks,” and, together with the Federal Home Loan Banks Office of Finance (“Office of Finance”), a joint office of the FHLBanks, the “FHLBank System”) that were created by the Federal Home Loan Bank Act of 1932 (as amended, the “FHLB Act”). The FHLBanks serve the public by enhancing the availability of credit for residential mortgages and targeted community development. The Bank serves eligible financial institutions in Arkansas, Louisiana, Mississippi, New Mexico and Texas (collectively, the Ninth District of the FHLBank System). The Bank provides a readily available, competitively priced source of funds to its member institutions. The Bank is a cooperative whose member institutions own the capital stock of the Bank. Regulated depository institutions and insurance companies engaged in residential housing finance and Community Development Financial Institutions that are certified under the Community Development Banking and Financial Institutions Act of 1994 may apply for membership in the Bank. All members must purchase stock in the Bank. Housing associates, including state and local housing authorities, that meet certain statutory criteria may also borrow from the Bank; while eligible to borrow, housing associates are not members of the Bank and, as such, are not required or allowed to hold capital stock. The Federal Housing Finance Agency (“Finance Agency”), an independent agency in the executive branch of the U.S. government, supervises and regulates the FHLBanks and the Office of Finance. The Finance Agency’s stated mission is to ensure that the housing government-sponsored enterprises ("GSEs"), including the FHLBanks, operate in a safe and sound manner so that they serve as a reliable source of liquidity and funding for housing finance and community investment. Consistent with this mission, the Finance Agency establishes policies and regulations covering the operations of the FHLBanks. Each FHLBank operates as a separate entity with its own management, employees, and board of directors. The Bank does not have any special purpose entities or any other type of off-balance sheet conduits. The Office of Finance facilitates the issuance and servicing of the FHLBanks’ debt instruments (known as consolidated obligations). As provided by the FHLB Act and Finance Agency regulation, the FHLBanks’ consolidated obligations are backed only by the financial resources of all 11 FHLBanks. Consolidated obligations are the joint and several obligations of all the FHLBanks and are the FHLBanks’ primary source of funds. Deposits, other borrowings, and the proceeds from capital stock issued to members provide other funds. The Bank primarily uses these funds to provide loans (known as advances) to its members, to purchase single-family mortgage loans from its members, and to fund other investments. The Bank’s credit services also include letters of credit issued or confirmed on behalf of members; in addition, the Bank offers interest rate swaps, caps and floors to its members. Further, the Bank provides its members with a variety of correspondent banking services, including overnight and term deposit accounts, wire transfer services, securities safekeeping and securities pledging services. |

Significant Accounting Policies [Abstract] | |
Significant Accounting Policies [Text Block] | Summary of Significant Accounting Policies Use of Estimates and Assumptions. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make assumptions and estimates. These assumptions and estimates may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expenses. Significant estimates include the valuations of the Bank’s investment securities, as well as its derivative instruments and any associated hedged items. Actual results could differ from these estimates. Federal Funds Sold, Securities Purchased Under Agreements to Resell, Loans to Other FHLBanks and Interest-Bearing Deposits. These investments are carried at cost. Investment Securities. The Bank records investment securities on trade date. The Bank carries investment securities for which it has both the ability and intent to hold to maturity (held-to-maturity securities) at cost, adjusted for the amortization of premiums and accretion of discounts using the level-yield method. The carrying amount of held-to-maturity securities is further adjusted for any other-than-temporary impairment charges, as described below. The Bank classifies certain investment securities that it may sell before maturity as available-for-sale and carries them at fair value. For available-for-sale securities that have been hedged (with fixed-for-floating interest rate swaps) and qualify as fair value hedges, the Bank records the portion of the change in value related to the risk being hedged in other income (loss) as “net gains (losses) on derivatives and hedging activities” together with the related change in the fair value of the derivative, and records the remainder of the change in value of the securities in other comprehensive income as “net unrealized gains (losses) on available-for-sale securities.” The Bank classifies certain other investments as trading and carries them at fair value. The Bank records changes in the fair value of these investments in other income (loss) in the statements of income. Although the securities are classified as trading, the Bank does not engage in active or speculative trading practices. The Bank computes the amortization and accretion of premiums and discounts on mortgage-backed securities ("MBS") for which prepayments are probable and reasonably estimable using the level-yield method over the estimated lives of the securities. This method requires a retrospective adjustment of the effective yield each time the Bank changes the estimated life as if the new estimate had been known since the original acquisition date of the securities. The Bank computes the amortization and accretion of premiums and discounts on other investments using the level-yield method to the contractual maturity of the securities. The Bank computes gains and losses on sales of investment securities using the specific identification method and includes these gains and losses in other income (loss) in the statements of income. The Bank treats securities purchased under agreements to resell as collateralized financings. The Bank evaluates outstanding available-for-sale and held-to-maturity securities for other-than-temporary impairment on a quarterly basis. An investment security is impaired if the fair value of the investment is less than its amortized cost. Amortized cost includes adjustments (if any) made to the cost basis of an investment for accretion, amortization, the credit portion of previous other-than-temporary impairments and hedging. The Bank considers the impairment of a debt security to be other than temporary if the Bank (i) intends to sell the security, (ii) more likely than not will be required to sell the security before recovering its amortized cost basis, or (iii) does not expect to recover the security’s entire amortized cost basis (even if the Bank does not intend to sell the security). Further, an impairment is considered to be other than temporary if the Bank’s best estimate of the present value of cash flows expected to be collected from the debt security is less than the amortized cost basis of the security (any such shortfall is referred to as a “credit loss”). If an other-than-temporary impairment (“OTTI”) occurs because the Bank intends to sell an impaired debt security, or more likely than not will be required to sell the security before recovery of its amortized cost basis, the impairment is recognized currently in earnings in an amount equal to the entire difference between fair value and amortized cost. In instances in which a determination is made that a credit loss exists but the Bank does not intend to sell the debt security and it is not more likely than not that the Bank will be required to sell the debt security before the anticipated recovery of its remaining amortized cost basis, the other-than-temporary impairment (i.e., the difference between the security’s then-current carrying amount and its estimated fair value) is separated into (i) the amount of the total impairment related to the credit loss (i.e., the credit component) and (ii) the amount of the total impairment related to all other factors (i.e., the non-credit component). The credit component is recognized in earnings and the non-credit component is recognized in other comprehensive income. The total other-than-temporary impairment is presented in the statement of income with an offset for the amount of the total other-than-temporary impairment that is recognized in other comprehensive income. The non-credit component of any OTTI losses recognized in other comprehensive income for debt securities classified as held-to-maturity is accreted over the remaining life of the debt security (in a prospective manner based on the amount and timing of future estimated cash flows) as an increase in the carrying value of the security unless and until the security is sold, the security matures, or there is an additional other-than-temporary impairment that is recognized in earnings. In instances in which an additional other-than-temporary impairment is recognized in earnings, the amount of the credit loss is reclassified from accumulated other comprehensive income (loss) ("AOCI") to earnings. Further, if an additional other-than-temporary impairment is recognized in earnings and the held-to-maturity security’s then-current carrying amount exceeds its fair value, an additional non-credit impairment is concurrently recognized in other comprehensive income. Conversely, if an additional other-than-temporary impairment is recognized in earnings and the held-to-maturity security’s then-current carrying value is less than its fair value, the carrying value of the security is not increased. In periods subsequent to the recognition of an OTTI loss, the other-than-temporarily impaired debt security is accounted for as if it had been purchased on the measurement date of the other-than-temporary impairment at an amount equal to the previous amortized cost basis less the other-than-temporary impairment recognized in earnings. The difference between the new amortized cost basis and the cash flows expected to be collected is accreted as interest income over the remaining life of the security in a prospective manner based on the amount and timing of future estimated cash flows. In instances when there is a significant increase in a security's expected cash flows, the amount to be accreted is adjusted prospectively. Advances. The Bank reports advances at their principal amount outstanding, net of unearned commitment fees and deferred prepayment fees, if any, as discussed below. The Bank credits interest on advances to income as earned. Mortgage Loans Held for Portfolio. Through the Mortgage Partnership Finance ® (“MPF” ® ) program administered by the FHLBank of Chicago, the Bank invests in conventional residential mortgage loans. Under the MPF program, the Bank purchased conventional mortgage loans and government-guaranteed/insured mortgage loans (i.e., those insured or guaranteed by the Federal Housing Administration (“FHA”) or the Department of Veterans Affairs (“DVA”)) during the period from 1998 to mid-2003. The Bank resumed acquiring conventional mortgage loans under this program in 2016. In 2017 and 2016, all of the acquired mortgage loans were originated by certain of the Bank's member institutions that participate in the MPF program ("Participating Financial Institutions" or “PFIs”) and the Bank acquired a 100 percent interest in such loans. For loans that were acquired from its members during the period from 1998 to mid-2003, the Bank retained title to the mortgage loans, subject to any participation interest in such loans that was sold to the FHLBank of Chicago; the interest in these loans that was retained by the Bank ranged from 1 percent to 49 percent. Additionally, during the period from 1998 to 2000, the Bank also acquired from the FHLBank of Chicago a percentage interest (ranging up to 75 percent) in certain MPF loans originated by PFIs of other FHLBanks. The Bank manages the liquidity, interest rate and prepayment risk of these loans, while the PFIs or their designees retain the servicing activities. The Bank and the PFIs share in the credit risk of the loans with the Bank assuming the first loss obligation limited by the First Loss Account (“FLA”), and the PFIs assuming credit losses in excess of the FLA, up to the amount of the credit enhancement obligation as specified in the master agreement (“Second Loss Credit Enhancement”). The Bank assumes all losses in excess of the Second Loss Credit Enhancement. The Bank classifies mortgage loans held for portfolio as held for investment and, accordingly, reports them at their principal amount outstanding net of deferred premiums, discounts and the fair value amount of the delivery commitment (which represents the unrealized gains and losses from loans initially classified as mortgage loan commitments) as of the purchase (i.e., settlement) date. The Bank credits interest on mortgage loans to income as earned. The Bank amortizes or accretes the deferred amounts to interest income using the contractual method. The contractual method uses the cash flows required by the loan contracts, as adjusted for any actual prepayments, to apply the interest method. Future prepayments of principal are not anticipated under this method. The Bank has the ability and intent to hold these mortgage loans until maturity. Allowance for Credit Losses. An allowance for credit losses is separately established for each of the Bank’s identified portfolio segments, if necessary, to provide for probable losses inherent in its financing receivables portfolio and other off-balance sheet credit exposures as of the balance sheet date. To the extent necessary, an allowance for credit losses for off-balance sheet credit exposures is recorded as a liability. See Note 8 — Allowance for Credit Losses for information regarding the determination of the allowance for credit losses. A portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. The Bank has developed and documented a systematic methodology for determining an allowance for credit losses for the following portfolio segments: (1) advances and other extensions of credit to members, collectively referred to as “extensions of credit to members;” (2) government-guaranteed/insured mortgage loans held for portfolio; and (3) conventional mortgage loans held for portfolio. Classes of financing receivables are generally a disaggregation of a portfolio segment and are determined on the basis of their initial measurement attribute, the risk characteristics of the financing receivable and an entity’s method for monitoring and assessing credit risk. Because the credit risk arising from the Bank’s financing receivables is assessed and measured at the portfolio segment level, the Bank does not have separate classes of financing receivables within each of its portfolio segments. The Bank places a conventional mortgage loan on nonaccrual status when the collection of the contractual principal or interest is 90 days or more past due. When a mortgage loan is placed on nonaccrual status, accrued but uncollected interest is reversed against interest income. The Bank records cash payments received on nonaccrual loans first as interest income until it recovers all interest, and then as a reduction of principal. A loan on nonaccrual status is restored to accrual status when none of its contractual principal and interest is due and unpaid, and the Bank expects repayment of the remaining contractual interest and principal. Government-guaranteed/insured loans are not placed on nonaccrual status. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Collateral-dependent loans that are on nonaccrual status are measured for impairment based on the fair value of the underlying mortgaged property less estimated selling costs. Loans are considered collateral-dependent if repayment is expected to be provided solely by the sale of the underlying property; that is, there is no other available and reliable source of repayment. A collateral-dependent loan is impaired if the fair value of the underlying collateral is insufficient to recover the unpaid principal balance on the loan. Interest income on impaired loans is recognized in the same manner as it is for nonaccrual loans noted above. The Bank evaluates whether to record a charge-off on a conventional mortgage loan when the loan becomes 180 days or more past due or upon the occurrence of a confirming event, whichever occurs first. Confirming events include, but are not limited to, the occurrence of foreclosure or notification of a claim against any of the credit enhancements. A charge-off is recorded if the recorded investment in the loan will not be recovered. Real Estate Owned. Real estate owned includes assets that have been received in satisfaction of debt or as a result of actual or in-substance foreclosures. Real estate owned is initially recorded at fair value less estimated costs to sell (and subsequently carried at the lower of cost or fair value less estimated costs to sell) and is included in other assets in the statements of condition. If the fair value of the real estate owned less estimated costs to sell is less than the recorded investment in the mortgage loan at the date of transfer, the Bank recognizes a charge-off to the allowance for loan losses. Subsequent realized gains and realized or unrealized losses are included in other income (loss) in the statements of income. Premises and Equipment. The Bank records premises and equipment at cost less accumulated depreciation and amortization. At December 31, 2017 and 2016 , the Bank’s accumulated depreciation and amortization relating to premises and equipment was $33,698,000 and $31,573,000 , respectively. The Bank computes depreciation using the straight-line method over the estimated useful lives of assets ranging from 3 to 39 years. It amortizes leasehold improvements on the straight-line basis over the shorter of the estimated useful life of the improvement or the remaining term of the lease. The Bank capitalizes improvements and major renewals but expenses ordinary maintenance and repairs when incurred. Depreciation and amortization expense was $2,212,000 , $2,124,000 and $2,176,000 during the years ended December 31, 2017, 2016 and 2015 , respectively. The Bank includes gains and losses on disposal of premises and equipment, if any, in other income (loss) under the caption “other, net.” Computer Software. The cost of purchased computer software and certain costs incurred in developing computer software for internal use are capitalized and amortized over future periods. As of December 31, 2017 and 2016 , the Bank had $3,264,000 and $2,635,000 , respectively, in unamortized computer software costs included in other assets. Amortization of computer software costs charged to expense was $1,518,000 , $1,944,000 and $1,744,000 for the years ended December 31, 2017, 2016 and 2015 , respectively. Derivatives and Hedging Activities. The Bank accounts for derivatives and hedging activities in accordance with the guidance in Topic 815 of the Financial Accounting Standards Board’s ("FASB") Accounting Standards Codification entitled “Derivatives and Hedging” (“ASC 815”). All derivatives are recognized on the statements of condition at their fair values, including accrued interest receivable and payable. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments (including the right to reclaim cash collateral and the obligation to return cash collateral) where a legally enforceable right of setoff exists. Changes in the fair value of a derivative that is effective as — and that is designated and qualifies as — a fair value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk (including changes that reflect gains or losses on firm commitments), are recorded in current period earnings. Any hedge ineffectiveness (which represents the amount by which the change in the fair value of the derivative differs from the change in the fair value of the hedged item attributable to the hedged risk) is recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” Net interest income/expense associated with derivatives that qualify for fair value hedge accounting under ASC 815 is recorded as a component of net interest income. If fair value hedging relationships meet certain criteria specified in ASC 815, they are eligible for hedge accounting and the offsetting changes in fair value of the hedged items may be recorded in earnings. The application of hedge accounting generally requires the Bank to evaluate the effectiveness of the fair value hedging relationships on an ongoing basis and to calculate the changes in fair value of the derivatives and related hedged items independently. This is commonly known as the “long-haul” method of accounting. Transactions that meet more stringent criteria qualify for the “shortcut” method of hedge accounting in which an assumption can be made that the change in fair value of a hedged item exactly offsets the change in value of the related derivative. The Bank considers hedges of committed advances to be eligible for the shortcut method of accounting as long as the settlement of the committed advance occurs within the shortest period possible for that type of instrument based on market settlement conventions, the fair value of the swap is zero at the inception of the hedging relationship, and the transaction meets all of the other criteria for shortcut accounting specified in ASC 815. The Bank has defined the market settlement convention to be five business days or less for advances. Changes in the fair value of a derivative that is designated and qualifies as a cash flow hedge, to the extent that the hedge is effective, are recorded in AOCI until earnings are affected by the variability of the cash flows of the hedged transaction. Any ineffective portion of a cash flow hedge (which represents the amount by which the change in the fair value of the derivative differs from the change in fair value of a hypothetical derivative having terms that match identically the critical terms of the hedged forecasted transaction) is recognized in other income (loss) as “net gains (losses) on derivatives and hedging activities.” An economic hedge is defined as a derivative hedging specific or non-specific assets or liabilities that does not qualify or was not designated for hedge accounting under ASC 815, but is an acceptable hedging strategy under the Bank’s Enterprise Market Risk Management Policy. These hedging strategies also comply with Finance Agency regulatory requirements prohibiting speculative derivative transactions. An economic hedge by definition introduces the potential for earnings variability as changes in the fair value of a derivative designated as an economic hedge are recorded in current period earnings with no offsetting fair value adjustment to an asset or liability. Both the net interest income/expense and the fair value changes associated with derivatives in economic hedging relationships are recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” The Bank records the changes in fair value of all derivatives (and, in the case of fair value hedges, the hedged items) beginning on the trade date. Cash flows associated with all derivatives are reported as cash flows from operating activities in the statements of cash flows, unless the derivative contains an other-than-insignificant financing element, in which case its cash flows are reported as cash flows from financing activities. The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is “embedded” and the financial instrument that embodies the embedded derivative instrument is not remeasured at fair value with changes in fair value reported in earnings as they occur. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as either (1) a hedging instrument in a fair value hedge or (2) a stand-alone derivative instrument pursuant to an economic hedge. However, if the entire contract were to be measured at fair value, with changes in fair value reported in current earnings, or if the Bank could not reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract would be carried on the statement of condition at fair value and no portion of the contract would be separately accounted for as a derivative. The Bank discontinues hedge accounting prospectively when: (1) management determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item; (2) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (3) it is no longer probable that a forecasted transaction will occur within the originally specified time frame; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management determines that designating the derivative as a hedging instrument in accordance with ASC 815 is no longer appropriate. In all cases in which hedge accounting is discontinued and the derivative remains outstanding, the Bank will carry the derivative at its fair value on the statement of condition, recognizing any additional changes in the fair value of the derivative in current period earnings. When fair value hedge accounting for a specific derivative is discontinued due to the Bank’s determination that such derivative no longer qualifies for hedge accounting treatment or because the derivative is terminated, the Bank will cease to adjust the hedged asset or liability for changes in fair value and amortize the cumulative basis adjustment on the formerly hedged item into earnings over its remaining term using the level-yield method. When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the Bank continues to carry the derivative on the statement of condition at its fair value, removing from the statement of condition any asset or liability that was recorded to recognize the firm commitment and recording it as a gain or loss in current period earnings. When cash flow hedge accounting for a specific derivative is discontinued due to the Bank's determination that such derivative no longer qualifies for hedge accounting treatment or because the derivative is terminated, the Bank will reclassify the cumulative fair value gains or losses recorded in AOCI as of the discontinuance date from AOCI into earnings when earnings are affected by the original forecasted transaction, except in cases where the cash flow hedge is discontinued because the forecasted transaction is no longer probable (i.e., the forecasted transaction will not occur in the originally expected period or within an additional two-month period of time thereafter). In such cases, any fair value gains or losses recorded in AOCI as of the determination date are immediately reclassified to earnings as a component of "gains (losses) on derivatives and hedging activities." Similarly, if the Bank expects at any time that continued reporting of a net loss in AOCI would lead to recognizing a net loss on the combination of the hedging instrument and hedged transaction in one or more future periods, the amount that is not expected to be recovered is immediately reclassified to earnings as a component of "gains (losses) on derivatives and hedging activities." Mandatorily Redeemable Capital Stock. The Bank reclassifies shares of capital stock from the capital section to the liability section of its statement of condition at the point in time when a member submits a written redemption notice, gives notice of its intent to withdraw from membership, or becomes a non-member by merger or acquisition, charter termination, or involuntary termination from membership, as the shares of capital stock then meet the definition of a mandatorily redeemable financial instrument. Shares of capital stock meeting this definition are reclassified to liabilities at fair value. Following reclassification of the stock, any dividends paid or accrued on such shares are recorded as interest expense in the statement of income. Repurchase or redemption of these mandatorily redeemable financial instruments is reported as a cash outflow in the financing activities section of the statement of cash flows. If a member cancels a written redemption or withdrawal notice, the Bank reclassifies the shares subject to the cancellation notice from liabilities back to equity. Following this reclassification to equity, dividends on the capital stock are once again recorded as a reduction of retained earnings. Although mandatorily redeemable capital stock is excluded from capital for financial reporting purposes, it is considered capital for regulatory purposes. See Note 14 for more information, including restrictions on stock redemption. Affordable Housing Program. The FHLB Act requires each FHLBank to establish and fund an Affordable Housing Program (“AHP”) (see Note 11). The Bank charges the required funding for AHP to earnings and establishes a liability. The Bank makes AHP funds available to members in the form of direct grants to assist in the purchase, construction, or rehabilitation of housing for very low-, low-, and moderate-income households. Prepayment Fees. The Bank charges a prepayment fee when members/borrowers prepay certain advances before their original maturities. The Bank records prepayment fees received from members/borrowers net of hedging adjustments included in the book basis of the prepaid advance, if any, as interest income on advances in the statements of income either immediately (as prepayment fees on advances) or over time (as interest income on advances), as further described below. In cases in which the Bank funds a new advance concurrent with or within a short period of time before or after the prepayment of an existing advance, the Bank evaluates whether the new advance meets the accounting criteria to qualify as a modification of an existing advance. If the new advance qualifies as a modification of the existing advance, the net prepayment fee on the prepaid advance is deferred, recorded in the basis of the modified advance, and amortized into interest income over the life of the modified advance using the level-yield method. This amortization is recorded in interest income on advances. If the Bank determines that the advance should be treated as a new advance, or in instances where no new advance is funded, it records the net fees as “prepayment fees on advances” in the interest income section of the statements of income. Commitment Fees. The Bank defers commitment fees for advances and amortizes them to interest income using the level-yield method over the life of the advance. The Bank records commitment fees for letters of credit as a deferred credit when it receives the fees and amortizes them over the term of the letter of credit using the straight-line method. Concessions on Consolidated Obligations. The Bank defers and amortizes, using the level-yield method, the amounts paid to securities dealers in connection with the sale of consolidated obligation bonds over the term to maturity of the related bonds. The Office of Finance prorates the amount of the concession to the Bank based upon the percentage of the debt issued that is assumed by the Bank. Unamortized concessions were $2,238,000 and $1,308,000 at December 31, 2017 and 2016 , respectively, and are recorded as a reduction in the balance of consolidated obligation bonds on the statements of condition. Amortization of such concessions is included in consolidated obligation bond interest expense and totaled $846,000 , $1,261,000 and $2,544,000 during the years ended December 31, 2017, 2016 and 2015 , respectively. The Bank charges to expense as incurred the concessions applicable to the sale of consolidated obligation discount notes because of the short maturities of these notes. Concessions related to the sale of discount notes totaling $3,589,000 , $3,394,000 and $1,274,000 are included in interest expense on consolidated obligation discount notes in the statements of income for the years ended December 31, 2017, 2016 and 2015 , respectively. Discounts and Premiums on Consolidated Obligations. The Bank expenses the discounts on consolidated obligation discount notes using the level-yield method over the term to maturity of the related notes. It accretes the discounts and amortizes the premiums on consolidated obligation bonds to expense using the level-yield method over the term to maturity of the bonds. Finance Agency and Office of Finance Expenses. The Bank is assessed its proportionate share of the costs of operating the Finance Agency and the Office of Finance. The assessment for the FHLBanks’ portion of the Finance Agency’s operating and capital expenditures is allocated among the FHLBanks based on the ratio between each FHLBank’s minimum required regulatory capital and the aggregate minimum required regulatory capital of all FHLBanks determined as of June 30 of each year. The expenses of the Office of Finance are shared on a pro rata basis with two-thirds based on each FHLBank’s total consolidated obligations outstanding (as of the current month-end) and one-third divided equally among all of the FHLBanks. These costs are included in the other expense section of the statements of income. Estimated Fair Values. Some of the Bank’s financial instruments (e.g., advances) lack an available trading market characterized by transactions between a willing buyer and a willing seller engaging in an exchange transaction. Therefore, the Bank uses internal models employing assumptions regarding interest rates, volatilities, prepayments, and other factors to perform present-value calculations when disclosing estimated fair values for these financial instruments. The Bank assumes that book value approximates fair value for certain financial instruments with three months or less to repricing or maturity. For a discussion of the Bank's valuation techniques and the estimated fair values of its financial instruments, see Note 16. Cash Flows. The Bank considers cash and due from banks as cash and cash equivalents in the statements of c |

Recently Issued Accounting Guidance [Abstract] | |
New Accounting Pronouncements and Changes in Accounting Principles [Text Block] | Recently Issued Accounting Guidance Revenue from Contracts with Customers. On May 28, 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09 "Revenue from Contracts with Customers" ("ASU 2014-09"), which outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. In addition, ASU 2014-09 amends the existing requirements for the recognition of a gain or loss on the transfer of non-financial assets that are not in a contract with a customer. ASU 2014-09 applies to all contracts with customers except those that are within the scope of certain other standards, such as financial instruments, certain guarantees, insurance contracts, and lease contracts. The guidance in ASU 2014-09 was effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 (January 1, 2017 for the Bank). Early application was not permitted. On August 12, 2015, the FASB issued ASU 2015-14 "Deferral of Effective Date," which deferred the effective date of ASU 2014-09 by one year. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Bank adopted ASU 2014-09 effective January 1, 2018. The adoption of this guidance did not have a material impact on the Bank's results of operations or financial condition. Recognition and Measurement of Financial Assets and Financial Liabilities . On January 5, 2016, the FASB issued ASU 2016-01 "Recognition and Measurement of Financial Assets and Financial Liabilities" ("ASU 2016-01"), which makes targeted improvements to existing U.S. GAAP by: (i) requiring certain equity investments to be measured at fair value with changes in fair value recognized in earnings, (ii) simplifying the impairment assessment of equity investments without readily determinable fair values, (iii) requiring public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (iv) requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the statement of condition or in the accompanying notes to the financial statements, (v) eliminating the requirement to disclose the fair value of financial instruments measured at amortized cost for organizations that are not public business entities, (vi) eliminating the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the statement of condition, (vii) requiring a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (also referred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, and (viii) clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets. For public business entities, the guidance in ASU 2016-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption was permitted for certain provisions. The Bank adopted ASU 2016-01 effective January 1, 2018. The adoption of ASU 2016-01 did not have a material impact on the Bank's results of operations or financial condition. Leases . On February 25, 2016, the FASB issued ASU 2016-02 "Leases" (“ASU 2016-02”), which requires entities that lease assets (lessees) to recognize in the statement of condition assets and liabilities for the rights and obligations created by those leases. Specifically, ASU 2016-02 requires a lessee of operating or finance leases to recognize a right-of-use asset and a liability to make lease payments for leases with terms of more than 12 months. Lessor accounting will remain largely unchanged from current U.S. GAAP. ASU 2016-02 also requires extensive quantitative and qualitative disclosures to help financial statement users understand the amount, timing and uncertainty of cash flows arising from leases. For public business entities, the guidance in ASU 2016-02 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 (January 1, 2019 for the Bank). Early adoption is permitted. The adoption of ASU 2016-02 is not expected to have a material impact on the Bank's results of operations or financial condition. Contingent Put and Call Options in Debt Instruments. On March 14, 2016, the FASB issued ASU 2016-06, "Contingent Put and Call Options in Debt Instruments" ("ASU 2016-06"), which clarifies the requirements for assessing whether contingent call or put options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. The guidance requires entities to apply only the four-step decision sequence when assessing whether the economic characteristics and risks of call or put options are clearly and closely related to the economic characteristics and risks of their debt hosts. Consequently, when a call or put option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call or put option is related to interest rates or credit risks. For public business entities, the guidance in ASU 2016-06 is effective for fiscal years beginning after December 15, 2016 (January 1, 2017 for the Bank), and interim periods within those fiscal years. Early adoption was permitted. The guidance was to be applied on a modified retrospective basis to existing debt instruments as of the beginning of the period for which the amendments were effective. The Bank adopted this guidance effective January 1, 2017. The adoption of ASU 2016-06 has not had any impact on the Bank's financial condition or results of operations. Credit Losses on Financial Instruments. On June 16, 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"), which amends the guidance for the accounting for credit losses on financial instruments by replacing the current incurred loss methodology with an expected credit loss methodology. Among other things, ASU 2016-13 requires: • entities to present financial assets, or groups of financial assets, measured at amortized cost at the net amount expected to be collected, which is computed by deducting an allowance for credit losses from the amortized cost basis of the financial asset(s); • the measurement of expected credit losses to be based upon relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount; • the statement of income to reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases in expected credit losses that have taken place during the period; • entities to determine the allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination ("PCD assets") that are measured at amortized cost in a manner similar to other financial assets measured at amortized cost (the initial allowance for credit losses on PCD assets is added to the purchase price rather than being reported as a credit loss expense); • credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses, the amount of which is limited to the amount by which fair value is below amortized cost; and • public business entities to further disaggregate the current disclosure of credit quality indicators in relation to the amortized cost of financing receivables by year of origination. For public business entities that file with the Securities and Exchange Commission, the guidance in ASU 2016-13 is effective for fiscal years beginning after December 15, 2019 (January 1, 2020 for the Bank), and interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The guidance is to be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period in which the amendments are adopted. However, entities are required to use a prospective transition approach for debt securities for which an other-than-temporary impairment had been recognized before the date of adoption. The Bank has not yet determined the effect that the adoption of ASU 2016-13 will have on its results of operations or financial condition. Classification of Certain Cash Receipts and Cash Payments. On August 26, 2016, the FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments" ("ASU 2016-15"), which clarifies the guidance for classifying certain cash receipts and cash payments in the statement of cash flows. The guidance is intended to reduce existing diversity in practice regarding eight specific cash flow presentation issues. For public business entities, the guidance in ASU 2016-15 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption, including adoption in an interim period, is permitted. The guidance is to be applied using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied as if the change was made prospectively as of the earliest date practicable. The Bank adopted ASU 2016-15 on January 1, 2018. The adoption of this guidance did not have any impact on the Bank's statement of cash flows, nor did it have any impact on the Bank's results of operations or financial condition. Restricted Cash. On November 17, 2016, the FASB issued ASU 2016-18, "Restricted Cash" ("ASU 2016-18"), which clarifies the guidance for classifying and presenting certain cash transfers, cash receipts and cash payments in the statement of cash flows. The guidance is intended to reduce existing diversity in practice regarding restricted cash and restricted cash equivalents. For public business entities, the guidance in ASU 2016-18 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption, including adoption in an interim period, is permitted. The guidance is to be applied using a retrospective transition method to each period presented. The adoption of ASU 2016-18 on January 1, 2018 did not have any impact on the Bank's statement of cash flows, nor did it have any impact on the Bank's results of operations or financial condition. Premium Amortization on Purchased Callable Debt Securities. On March 30, 2017, the FASB issued ASU 2017-08, "Premium Amortization on Purchased Callable Debt Securities" ("ASU 2017-08"), which amends the amortization period for certain purchased callable debt securities held at a premium, shortening such period to the earliest call date. For public business entities, the guidance in ASU 2017-08 is effective for fiscal years beginning after December 15, 2018 (January 1, 2019 for the Bank), and interim periods within those fiscal years. Early adoption, including adoption in an interim period, is permitted. If an entity early adopts ASU 2017-08 in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The guidance is to be applied using a modified retrospective transition approach, with the cumulative-effect adjustment recognized in retained earnings as of the beginning of the period of adoption. The adoption of ASU 2017-08 is not expected to have a material impact on the Bank's results of operations or financial condition. Derivatives and Hedging. On August 28, 2017, the FASB issued ASU 2017-12, "Targeted Improvements to Accounting for Hedging Activities" ("ASU 2017-12"), which is intended to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. This guidance requires that, for fair value hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness be presented in the same income statement line that is used to present the earnings effect of the hedged item. For cash flow hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness must be recorded in other comprehensive income. In addition, the guidance includes certain targeted improvements to the assessment of hedge effectiveness and permits, among other things, the following: • For fair value hedges, measurement of the change in fair value of the hedged item on the basis of the benchmark rate component of the contractual coupon cash flows determined at hedge inception. • Partial-term fair value hedges of interest-rate risk, in which it can be assumed that the hedged item has a term that reflects only the designated cash flows being hedged. • For prepayable financial instruments, consideration only of how changes in the benchmark interest rate affect a decision to settle a debt instrument before its scheduled maturity in calculating the change in the fair value of the hedged item attributable to interest rate risk. • For a cash flow hedge of interest-rate risk of a variable-rate financial instrument, designation of the variability in cash flows attributable to the contractually specified interest rate as the hedged risk. • For a closed portfolio of prepayable financial assets or one or more beneficial interests secured by a portfolio of prepayable financial instruments, designation of an amount that is not expected to be affected by prepayments, defaults and other events affecting the timing and amount of cash flows as a hedged item. For public business entities, the guidance in ASU 2017-12 is effective for fiscal years beginning after December 15, 2018 (January 1, 2019 for the Bank), and interim periods within those fiscal years. Early adoption, including adoption in an interim period, is permitted. If an entity early adopts ASU 2017-12 in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The guidance is to be applied to hedging relationships existing at the date of adoption using a modified retrospective transition approach as of the beginning of the year of adoption. For cash flow hedges existing on the date of adoption, the cumulative-effect adjustment is recognized in accumulated other comprehensive income with a corresponding adjustment to retained earnings. The amended presentation and disclosure guidance is required only prospectively. The Bank will adopt ASU 2017-12 effective January 1, 2019. The Bank has not yet determined the effect that the adoption of ASU 2017-12 will have on its results of operations or financial condition. |

Other debentures are comprised of securities issued by the Private Export Funding Corporation ("PEFCO"). These debentures are fully secured by U.S. government-guaranteed obligations and the payment of interest on the debentures is guaranteed by an agency of the U.S. government.

All of the Bank's available-for-sale securities are either guaranteed by the U.S. government, issued by GSEs or fully secured by collateral that is guaranteed by the U.S. government. As of December 31, 2017 , the U.S. government and the issuers of the Bank’s holdings of GSE debentures and GSE commercial MBS were rated triple-A by Moody’s Investors Service (“Moody’s”) and Fitch Ratings, Ltd. (“Fitch”) and AA+ by S&P Global Ratings (“S&P”). The Bank's holdings of PEFCO debentures were rated triple-A by Moody's and Fitch, and were not rated by S&P at that date. Based upon the Bank's assessment of the creditworthiness of the issuer of the GSE debenture that was in an unrealized loss position at December 31, 2017 and the credit ratings assigned by each of the nationally recognized statistical rating organizations (“NRSROs”), the Bank expects that this debenture would not be settled at an amount less than the Bank's amortized cost basis in the investment. In addition, based upon the Bank's assessment of the strength of the GSEs' guarantees of the Bank's holdings of GSE commercial MBS and the credit ratings assigned by each of the NRSROs, the Bank expects that its holdings of GSE commercial MBS that were in an unrealized loss position at December 31, 2017 would not be settled at an amount less than the Bank’s amortized cost bases in these investments. Because the current market value deficits associated with the Bank's available-for-sale securities are not attributable to credit quality, and because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases, the Bank does not consider any of these investments to be other-than-temporarily impaired at December 31, 2017 . Redemption Terms. The amortized cost and estimated fair value of available-for-sale securities by contractual maturity at December 31, 2017 and 2016 are presented below (in thousands).

As of December 31, 2017 , the U.S. government and the issuers of the Bank's holdings of GSE MBS were rated triple-A by Moody's and Fitch and AA+ by S&P. Based upon the Bank's assessment of the strength of the government guaranty, the Bank expects that the U.S. government-guaranteed debenture that was in an unrealized loss position at December 31, 2017 would not be settled at an amount less than the Bank's amortized cost basis in the investment. In addition, based upon the Bank’s assessment of the strength of the GSEs' guarantees and the credit ratings assigned by the NRSROs, the Bank expects that its holdings of GSE MBS that were in an unrealized loss position at December 31, 2017 would not be settled at an amount less than the Bank’s amortized cost bases in these investments. Finally, based upon the Bank’s assessment of the creditworthiness of the state housing agency and the triple-A credit ratings assigned by the NRSROs, the Bank expects that the state housing agency debenture that was in an unrealized loss position at December 31, 2017 would not be settled at an amount less than the Bank’s amortized cost basis in this investment. Because the current market value deficits associated with these securities are not attributable to credit quality, and because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases, the Bank does not consider any of these investments to be other-than-temporarily impaired at December 31, 2017 . The deterioration in the U.S. housing markets that occurred primarily during the period from 2007 through 2011, as reflected during that period by declines in the values of residential real estate and higher levels of delinquencies, defaults and losses on residential mortgages, including the mortgages underlying the Bank’s non-agency residential MBS ("RMBS"), generally increased the risk that the Bank may not ultimately recover the entire cost bases of some of its non-agency RMBS. However, based upon its analysis of the securities in this portfolio, the Bank believes that the unrealized losses as of December 31, 2017 were principally the result of liquidity risk related discounts in the non-agency RMBS market and do not accurately reflect the currently likely future credit performance of the securities. Because the ultimate receipt of contractual payments on the Bank’s non-agency RMBS will depend upon the credit and prepayment performance of the underlying loans and the credit enhancements for the senior securities owned by the Bank, the Bank monitors these investments in an effort to determine whether the credit enhancement associated with each security is sufficient to protect against potential losses of principal and interest on the underlying mortgage loans. The credit enhancement for each of the Bank’s non-agency RMBS is provided by a senior/subordinate structure, and none of the securities owned by the Bank are insured by third-party bond insurers. More specifically, each of the Bank’s non-agency RMBS represents a single security class within a securitization that has multiple classes of securities. Each security class has a distinct claim on the cash flows from the underlying mortgage loans, with the subordinate securities having a junior claim relative to the more senior securities. The Bank’s non-agency RMBS have a senior claim on the cash flows from the underlying mortgage loans. To assess whether the entire amortized cost bases of its 23 non-agency RMBS holdings are likely to be recovered, the Bank performed a cash flow analysis for each security as of the end of each calendar quarter in 2017 using two third-party models. The first model considers borrower characteristics and the particular attributes of the loans underlying the Bank’s securities, in conjunction with assumptions about future changes in home prices and interest rates, to project prepayments, defaults and loss severities. A significant input to the first model is the forecast of future housing price changes for the relevant states and core based statistical areas (“CBSAs”), which are based upon an assessment of the individual housing markets. (The term “CBSA” refers collectively to metropolitan and micropolitan statistical areas as defined by the U.S. Office of Management and Budget; as currently defined, a CBSA must contain at least one urban area of 10,000 or more people.) The Bank’s housing price forecast as of December 31, 2017 assumed changes in home prices ranging from declines of 5 percent to increases of 12 percent over the 12-month period beginning October 1, 2017 . For the vast majority of markets, the changes were projected to range from increases of 2 percent to 6 percent . Thereafter, home price changes for each market were projected to return (at varying rates and over varying transition periods based on historical housing price patterns) to their long-term historical equilibrium levels. Following these transition periods, the constant long-term annual rates of appreciation for the vast majority of markets were projected to range between 2 percent and 5 percent . The month-by-month projections of future loan performance derived from the first model, which reflect projected prepayments, defaults and loss severities, are then input into a second model that allocates the projected loan level cash flows and losses to the various security classes in the securitization structure in accordance with its prescribed cash flow and loss allocation rules. In a securitization in which the credit enhancement for the senior securities is derived from the presence of subordinate securities, losses are generally allocated first to the subordinate securities until their principal balance is reduced to zero. Based on the results of its cash flow analyses, the Bank determined it is likely that it will fully recover the remaining amortized cost bases of all of its non-agency RMBS. Because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their remaining amortized cost bases, none of the Bank's non-agency RMBS were deemed to be other-than-temporarily impaired in 2017 . During the year ended December 31, 2016, one of the Bank's non-agency RMBS was determined to be other-than-temporarily impaired. In addition, 14 of the Bank's holdings of non-agency RMBS were determined to be other-than-temporarily impaired in periods prior to 2013. The following table presents a rollforward for the years ended December 31, 2017, 2016 and 2015 of the amount related to credit losses on the Bank’s non-agency RMBS holdings for which a portion of an other-than-temporary impairment was recognized in other comprehensive income (loss) (in thousands).

Sales of Securities. During the year ended December 31, 2017 , the Bank sold held-to-maturity securities with an amortized cost (determined by the specific identification method) of $158,806,000 . Proceeds from the sales totaled $162,789,000 , resulting in realized gains of $3,983,000 . During the year ended December 31, 2016 , the Bank sold held-to-maturity securities with an amortized cost (determined by the specific identification method) of $156,707,000 . Proceeds from the sales totaled $157,647,000 , resulting in realized gains of $940,000 . During the year ended December 31, 2015 the Bank sold held-to-maturity securities with an amortized cost (determined by the specific identification method) of $806,809,000 . Proceeds from the sales totaled $821,323,000 , resulting in realized gains of $14,514,000 . For each of these securities, the Bank had previously collected at least 85 percent of the principal outstanding at the time of acquisition. As such, the sales were considered maturities for purposes of security classification. |

Advances [Text Block] | Advances Redemption Terms. At December 31, 2017 and 2016 , the Bank had advances outstanding at interest rates ranging from 0.54 percent to 8.27 percent and from 0.40 percent to 8.27 percent , respectively, as summarized below (dollars in thousands). 2017 2016 Contractual Maturity Amount Weighted Average Interest Rate Amount Weighted Average Interest Rate Overdrawn demand deposit accounts $ 4,826 1.55 % $ — — % Due in one year or less 23,695,214 1.41 17,477,220 0.71 Due after one year through two years 1,735,507 1.64 5,115,095 1.07 Due after two years through three years 1,634,252 1.87 1,059,823 1.63 Due after three years through four years 639,113 1.94 1,347,926 1.56 Due after four years through five years 1,064,930 1.75 593,061 1.74 Due after five years 6,318,785 1.49 5,431,116 0.85 Amortizing advances 1,376,084 2.66 1,448,003 2.76 Total par value 36,468,711 1.52 % 32,472,244 0.97 % Premiums 23 52 Deferred net prepayment fees (11,271 ) (13,272 ) Commitment fees (116 ) (123 ) Hedging adjustments 3,177 47,274 Total $ 36,460,524 $ 32,506,175 The balances of overdrawn demand deposit accounts were fully collateralized at December 31, 2017 and were repaid at the beginning of 2018. Amortizing advances require repayment according to predetermined amortization schedules. The Bank offers advances to members that may be prepaid on specified dates without the member incurring prepayment or termination fees (prepayable and callable advances). The prepayment of other advances requires the payment of a fee to the Bank (prepayment fee) if necessary to make the Bank financially indifferent to the prepayment of the advance. At December 31, 2017 and 2016 , the Bank had aggregate prepayable and callable advances totaling $9,684,619,000 and $12,432,264,000 , respectively. The following table summarizes advances outstanding at December 31, 2017 and 2016 , by the earlier of contractual maturity or next call date, or the first date on which prepayable advances can be repaid without a prepayment fee (in thousands): Contractual Maturity or Next Call Date December 31, 2017 December 31, 2016 Overdrawn demand deposit accounts $ 4,826 $ — Due in one year or less 30,795,524 25,953,500 Due after one year through two years 1,335,427 2,336,974 Due after two years through three years 941,452 989,223 Due after three years through four years 490,913 757,626 Due after four years through five years 538,660 443,311 Due after five years 985,825 543,607 Amortizing advances 1,376,084 1,448,003 Total par value $ 36,468,711 $ 32,472,244 The Bank also offers putable advances. With a putable advance, the Bank purchases a put option from the member that allows the Bank to terminate the fixed-rate advance on specified dates and offer, subject to certain conditions, replacement funding at prevailing market rates. At December 31, 2017 and 2016 , the Bank had putable advances outstanding totaling $1,113,500,000 and $1,053,071,000 , respectively. The following table summarizes advances at December 31, 2017 and 2016 , by the earlier of contractual maturity or next possible put date (in thousands): Contractual Maturity or Next Put Date 2017 2016 Overdrawn demand deposit accounts $ 4,826 $ — Due in one year or less 24,269,214 18,153,670 Due after one year through two years 1,785,507 4,473,645 Due after two years through three years 1,641,752 1,024,823 Due after three years through four years 639,113 1,347,926 Due after four years through five years 1,029,930 593,061 Due after five years 5,722,285 5,431,116 Amortizing advances 1,376,084 1,448,003 Total par value $ 36,468,711 $ 32,472,244 Credit Concentrations. Due to the composition of its shareholders, the Bank’s potential credit risk from advances is concentrated in commercial banks and savings institutions. No borrower represented more than 10 percent of advances outstanding at December 31, 2017 , 2016 or 2015 . Interest Rate Payment Terms. The following table provides interest rate payment terms for advances outstanding at December 31, 2017 and 2016 (in thousands): 2017 2016 Fixed-rate Due in one year or less $ 20,628,666 $ 13,417,280 Due after one year 5,543,774 6,215,744 Total fixed-rate 26,172,440 19,633,024 Variable-rate Due in one year or less 3,154,361 4,136,153 Due after one year 7,141,910 8,703,067 Total variable-rate 10,296,271 12,839,220 Total par value $ 36,468,711 $ 32,472,244 At December 31, 2017 and 2016 , 19 percent and 25 percent, respectively, of the Bank’s fixed-rate advances were swapped to a variable rate. Prepayment Fees. When a member/borrower prepays an advance, the Bank could suffer lower future income if the principal portion of the prepaid advance is reinvested in lower-yielding assets. To protect against this risk, the Bank generally charges a prepayment fee that makes it financially indifferent to a borrower’s decision to prepay an advance. As discussed in Note 1, the Bank records prepayment fees received from members/borrowers on prepaid advances net of any associated hedging adjustments on those advances. Gross advance prepayment fees received from members/borrowers during the years ended December 31, 2017, 2016 and 2015 were $2,158,000 , $9,317,000 and $27,724,000 , respectively. During the years ended December 31, 2017, 2016 and 2015 , the Bank deferred $884,000 , $681,000 and $6,398,000 of these gross advance prepayment fees. The Bank also offers advances that include a symmetrical prepayment feature which allows a member to prepay an advance at the lower of par value or fair value plus a make-whole amount payable to the Bank. During the year ended December 31, 2017 , symmetrical prepayment advances with an aggregate par value of $17,000,000 were prepaid. The differences by which the par values of these advances exceeded their fair values, less the make-whole amounts, totaled $194,000 and were recorded in prepayment fees on advances, net of the associated hedging adjustments on the advances. There were no prepayments of symmetrical prepayment advances during the years ended December 31, 2016 or 2015 . |

Mortgage Loans Held for Portfolio [Abstract] | |
Mortgage Loans on Real Estate, by Loan Disclosure [Text Block] | Mortgage Loans Held for Portfolio Mortgage loans held for portfolio represent held-for-investment loans acquired through the MPF program (see Note 1). The following table presents information as of December 31, 2017 and 2016 for mortgage loans held for portfolio (in thousands): 2017 2016 Fixed-rate medium-term* single-family mortgages $ 9,279 $ 7,677 Fixed-rate long-term single-family mortgages 844,078 114,168 Premiums 22,123 1,783 Discounts (212 ) (209 ) Deferred net derivative gains associated with mortgage delivery commitments 2,855 683 Total mortgage loans held for portfolio 878,123 124,102 Less: allowance for credit losses (271 ) (141 ) Total mortgage loans held for portfolio, net of allowance for credit losses $ 877,852 $ 123,961 ________________________________________ *Medium-term is defined as an original term of 15 years or less. The unpaid principal balance of mortgage loans held for portfolio at December 31, 2017 and 2016 was comprised of government-guaranteed/insured loans totaling $19,228,000 and $23,426,000 , respectively, and conventional loans totaling $834,129,000 and $98,419,000 , respectively. PFIs are paid a credit enhancement fee (“CE fee”) as an incentive to minimize credit losses, to share in the risk of loss on MPF loans and to pay for supplemental mortgage insurance, rather than paying a guaranty fee to other secondary market purchasers. CE fees are paid monthly and are determined based on the remaining unpaid principal balance of the MPF loans. The required credit enhancement obligation varies depending upon the MPF product type. CE fees, payable to a PFI as compensation for assuming credit risk, are recorded as a reduction to mortgage loan interest income when paid by the Bank. During the years ended December 31, 2017, 2016 and 2015 , mortgage loan interest income was reduced by CE fees totaling $345,000 , $28,000 and $21,000 , respectively. The Bank also pays performance-based CE fees that are based on the actual performance of the pool of MPF loans under each individual master commitment. To the extent that losses in the current month exceed accrued performance-based CE fees, the remaining losses may be recovered from future performance-based CE fees payable to the PFI. During the years ended December 31, 2017, 2016 and 2015 , performance-based CE fees that were forgone and not paid to the Bank’s PFIs totaled $10,000 , $14,000 and $18,000 , respectively. |

Allowance for Credit Losses [Abstract] | |
Allowance for Credit Losses [Text Block] | Allowance for Credit Losses The Bank has established an allowance methodology for each of its portfolio segments: advances and other extensions of credit to members/borrowers, collectively referred to as "extensions of credit to members"; government-guaranteed/insured mortgage loans held for portfolio; and conventional mortgage loans held for portfolio. Advances and Other Extensions of Credit to Members. In accordance with federal statutes, including the FHLB Act, the Bank lends to financial institutions within its five-state district that are involved in housing finance. The FHLB Act requires the Bank to obtain and maintain sufficient collateral for advances and other extensions of credit to protect against losses. The Bank makes advances and otherwise extends credit only against eligible collateral, as defined by regulation. Eligible collateral includes whole first mortgages on improved residential real property (not more than 90 days delinquent), or securities representing a whole interest in such mortgages; securities issued, insured, or guaranteed by the U.S. government or any of its agencies, including mortgage-backed and other debt securities issued or guaranteed by the Federal National Mortgage Association (“Fannie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or the Government National Mortgage Association (“Ginnie Mae”); term deposits in the Bank; and other real estate-related collateral acceptable to the Bank, provided that such collateral has a readily ascertainable value and the Bank can perfect a security interest in such property. In the case of Community Financial Institutions (which for 2017 included all FDIC-insured institutions with average total assets as of December 31, 2016 , 2015 and 2014 of less than $1.148 billion ), the Bank may also accept as eligible collateral secured small business, small farm and small agribusiness loans, securities representing a whole interest in such loans, and secured loans for community development activities. To ensure the value of collateral pledged to the Bank is sufficient to secure its advances and other extensions of credit, the Bank applies various haircuts, or discounts, to the collateral to determine the value against which borrowers may borrow. As additional security, the Bank has a statutory lien on each borrower’s capital stock in the Bank. Each member/borrower of the Bank executes a security agreement pursuant to which such member/borrower grants a security interest in favor of the Bank in certain assets of such member/borrower. The agreements under which a member grants a security interest fall into one of two general structures. In the first structure, the member grants a security interest in all of its assets that are included in the eligible collateral categories, as described in the preceding paragraph, which the Bank refers to as a “blanket lien.” A member may request that its blanket lien be modified, such that the member grants in favor of the Bank a security interest limited to certain of the eligible collateral categories (i.e., whole first residential mortgages, securities, term deposits in the Bank and other real estate-related collateral). In the second structure, the member grants a security interest in specifically identified assets rather than in the broad categories of eligible collateral covered by the blanket lien and the Bank identifies such members as being on “specific collateral only status.” The basis upon which the Bank will lend to a member that has granted the Bank a blanket lien depends on numerous factors, including, among others, that member’s financial condition and general creditworthiness. Generally, and subject to certain limitations, a member that has granted the Bank a blanket lien may borrow up to a specified percentage of the value of eligible collateral categories, as determined from such member’s financial reports filed with its federal regulator, without specifically identifying each item of collateral or delivering the collateral to the Bank. Under certain circumstances, including, among others, a deterioration of a member’s financial condition or general creditworthiness, the amount a member may borrow is determined on the basis of only that portion of the collateral subject to the blanket lien that such member delivers to the Bank. Under these circumstances, the Bank places the member on “custody status.” In addition, members on blanket lien status may choose to deliver some or all of the collateral to the Bank. The members/borrowers that are granted specific collateral only status by the Bank are typically either insurance companies or members/borrowers with an investment grade credit rating from at least two NRSROs that have requested this type of structure. Insurance companies are permitted to borrow only against the eligible collateral that is delivered to the Bank or a third-party custodian approved by the Bank, and insurance companies generally grant a security interest only in collateral they have delivered. Members/borrowers with an investment grade credit rating from at least two NRSROs may grant a security interest in, and would only be permitted to borrow against, delivered eligible securities and specifically identified, eligible first-lien mortgage loans. Such loans must be delivered to the Bank or a third-party custodian approved by the Bank, or the Bank and such member/borrower must otherwise take actions that ensure the priority of the Bank’s security interest in such loans. Investment grade rated members/borrowers that choose this option are subject to fewer provisions that allow the Bank to demand additional collateral or exercise other remedies based on the Bank’s discretion; however, the collateral they pledge is generally subject to larger haircuts (depending on the credit rating of the member/borrower from time to time) than are applied to similar types of collateral pledged by members under a blanket lien arrangement. The Bank perfects its security interests in borrowers’ collateral in a number of ways. The Bank usually perfects its security interest in collateral by filing a Uniform Commercial Code financing statement against the borrower. In the case of certain borrowers, the Bank perfects its security interest by taking possession or control of the collateral, which may be in addition to the filing of a financing statement. In these cases, the Bank also generally takes assignments of most of the mortgages and deeds of trust that are designated as collateral. Instead of requiring delivery of the collateral to the Bank, the Bank may allow certain borrowers to deliver specific collateral to a third-party custodian approved by the Bank or otherwise take actions that ensure the priority of the Bank’s security interest in such collateral. With certain exceptions set forth below, Section 10(e) of the FHLB Act affords any security interest granted to the Bank by any member/borrower of the Bank, or any affiliate of any such member/borrower, priority over the claims and rights of any party, including any receiver, conservator, trustee, or similar party having rights of a lien creditor. However, the Bank’s security interest is not entitled to priority over the claims and rights of a party that (i) would be entitled to priority under otherwise applicable law and (ii) is an actual bona fide purchaser for value or is a secured party who has a perfected security interest in such collateral in accordance with applicable law (e.g., a prior perfected security interest under the Uniform Commercial Code or other applicable law). For example, in a case in which the Bank has perfected its security interest in collateral by filing a Uniform Commercial Code financing statement against the borrower, another secured party’s security interest in that same collateral that was perfected by possession and without prior knowledge of the Bank's lien may be entitled to priority over the Bank’s security interest that was perfected by filing a Uniform Commercial Code financing statement. From time to time, the Bank agrees to subordinate its security interest in certain assets or categories of assets granted by a member/borrower of the Bank to the security interest of another creditor (typically, a Federal Reserve Bank or another FHLBank). If the Bank agrees to subordinate its security interest in certain assets or categories of assets granted by a member/borrower of the Bank to the security interest of another creditor, the Bank will not extend credit against those assets or categories of assets. On at least a quarterly basis, the Bank evaluates all outstanding extensions of credit to members/borrowers for potential credit losses. These evaluations include a review of: (1) the amount, type and performance of collateral available to secure the outstanding obligations; (2) metrics that may be indicative of changes in the financial condition and general creditworthiness of the member/borrower; and (3) the payment status of the obligations. Any outstanding extensions of credit that exhibit a potential credit weakness that could jeopardize the full collection of the outstanding obligations would be classified as substandard, doubtful or loss. The Bank did not have any advances or other extensions of credit to members/borrowers that were classified as substandard, doubtful or loss at December 31, 2017 or 2016 . The Bank considers the amount, type and performance of collateral to be the primary indicator of credit quality with respect to its extensions of credit to members/borrowers. At December 31, 2017 and 2016 , the Bank had rights to collateral on a borrower-by-borrower basis with an estimated value in excess of each borrower’s outstanding extensions of credit. The Bank continues to evaluate and, as necessary, modify its credit extension and collateral policies based on market conditions. At December 31, 2017 and 2016 , the Bank did not have any advances that were past due, on nonaccrual status, or considered impaired. There have been no troubled debt restructurings related to advances. The Bank has never experienced a credit loss on an advance or any other extension of credit to a member/borrower and, based on its credit extension and collateral policies, management currently does not anticipate any credit losses on its extensions of credit to members/borrowers. Accordingly, the Bank has not provided any allowance for credit losses on advances, nor has it recorded any liabilities to reflect an allowance for credit losses related to its off-balance sheet credit exposures. Mortgage Loans — Government-guaranteed/Insured. The Bank’s government-guaranteed/insured fixed-rate mortgage loans are insured or guaranteed by the FHA or the DVA. Any losses from these loans are expected to be recovered from those entities. Any losses from these loans that are not recovered from those entities are absorbed by the servicers. Therefore, the Bank has not established an allowance for credit losses on government-guaranteed/insured mortgage loans. Mortgage Loans — Conventional Mortgage Loans. The allowance for losses on conventional mortgage loans is determined by an analysis that includes consideration of various data such as past performance, current performance, loan portfolio characteristics, collateral-related characteristics and prevailing economic conditions. The allowance for losses on conventional mortgage loans also factors in the credit enhancement under the MPF program. Any incurred losses that are expected to be recovered from the credit enhancements are not reserved as part of the Bank’s allowance for loan losses. The Bank considers the key credit quality indicator for conventional mortgage loans to be the payment status of each loan. The table below summarizes the recorded investment (including accrued interest) by payment status for mortgage loans at December 31, 2017 and 2016 (dollars in thousands). December 31, 2017 December 31, 2016 Conventional Loans Government- Guaranteed/ Insured Loans Total Conventional Loans Government- Guaranteed/ Insured Loans Total Mortgage loans: 30-59 days delinquent $ 6,553 $ 983 $ 7,536 $ 899 $ 989 $ 1,888 60-89 days delinquent 1,541 148 1,689 191 172 363 90 days or more delinquent 689 98 787 276 130 406 Total past due 8,783 1,229 10,012 1,366 1,291 2,657 Total current loans 853,653 18,203 871,856 99,690 22,386 122,076 Total mortgage loans $ 862,436 $ 19,432 $ 881,868 $ 101,056 $ 23,677 $ 124,733 Other delinquency statistics: In process of foreclosure (1) $ 212 $ — $ 212 $ 57 $ 28 $ 85 Serious delinquency rate (2) 0.1 % 0.5 % 0.1 % 0.3 % 0.6 % 0.3 % Past due 90 days or more and still accruing interest (3) $ — $ 98 $ 98 $ — $ 130 $ 130 Nonaccrual loans $ 689 $ — $ 689 $ 276 $ — $ 276 Troubled debt restructurings $ — $ — $ — $ — $ — $ — ________________________________________ (1) Includes loans where the decision of foreclosure or similar alternative such as pursuit of deed-in-lieu has been made. (2) Loans that are 90 days or more past due or in the process of foreclosure expressed as a percentage of the loan portfolio. (3) Only government-guaranteed/insured mortgage loans continue to accrue interest after they become 90 days or more past due. At December 31, 2017 and 2016 , the Bank’s other assets included $49,000 and $89,000 , respectively, of real estate owned. Mortgage loans are considered impaired when, based upon current information and events, it is probable that the Bank will be unable to collect all principal and interest amounts due according to the contractual terms of the mortgage loan agreement. Each nonaccrual mortgage loan and each troubled debt restructuring is specifically reviewed for impairment. At December 31, 2017 and 2016 , the estimated value of the collateral securing each of these loans, plus the estimated amount that can be recovered through credit enhancements and mortgage insurance, if any, exceeded the outstanding loan amount. Therefore, no specific reserve was established for any of these mortgage loans. The remaining conventional mortgage loans were evaluated for impairment on a pool basis. Based upon the current and past performance of these loans and current economic conditions, the Bank determined that an allowance for loan losses of $271,000 was adequate to reserve for credit losses in its conventional mortgage loan portfolio at December 31, 2017 . The following table presents the activity in the allowance for credit losses on conventional mortgage loans held for portfolio during the years ended December 31, 2017, 2016 and 2015 (in thousands): Year Ended December 31, 2017 2016 2015 Balance, beginning of year $ 141 $ 141 $ 143 Chargeoffs — — (2 ) Provision for credit losses 130 — — Balance, end of year $ 271 $ 141 $ 141 The following table presents information regarding the balances of the Bank's conventional mortgage loans held for portfolio that were individually or collectively evaluated for impairment as well as information regarding the ending balance of the allowance for credit losses as of December 31, 2017 and 2016 (in thousands).

Deposits Liabilities Disclosures [Text Block] | Deposits The Bank offers demand and overnight deposits for members and qualifying non-members. In addition, the Bank offers short-term interest-bearing deposit programs to members and qualifying non-members. Interest-bearing deposits classified as demand and overnight pay interest based on a daily interest rate. Term deposits pay interest based on a fixed rate, or a stepped fixed rate schedule, that is determined on the issuance date of the deposit. The weighted average interest rates paid on average outstanding deposits were 0.89 percent, 0.28 percent and 0.03 percent during 2017 , 2016 and 2015 , respectively. For additional information regarding other interest-bearing deposits, see Note 13.

Debt Disclosure [Abstract] | |
Debt Disclosure [Text Block] | Consolidated Obligations Consolidated obligations are the joint and several obligations of the FHLBanks and consist of consolidated obligation bonds and discount notes. Consolidated obligations are backed only by the financial resources of the 11 FHLBanks. Consolidated obligations are not obligations of, nor are they guaranteed by, the U.S. government. The FHLBanks issue consolidated obligations through the Office of Finance as their agent. In connection with each debt issuance, one or more of the FHLBanks specifies the amount of debt it wants issued on its behalf; the Bank receives the proceeds of only the debt issued on its behalf and records on its statements of condition only that portion of the consolidated obligations for which it has received the proceeds. The Finance Agency and the U.S. Secretary of the Treasury have oversight over the issuance of FHLBank debt through the Office of Finance. Consolidated obligation bonds are issued primarily to raise intermediate- and long-term funds for the FHLBanks and are not subject to any statutory or regulatory limits on maturity. Consolidated obligation discount notes are issued to raise short-term funds and have maturities of one year or less. These notes are generally issued at a price that is less than their face amount and are redeemed at par value when they mature. For additional information regarding the FHLBanks’ joint and several liability on consolidated obligations, see Note 17. The par amounts of the FHLBanks’ outstanding consolidated obligations, including consolidated obligations held as investments by other FHLBanks, were approximately $1.034 trillion and $0.989 trillion at December 31, 2017 and 2016 , respectively. The Bank was the primary obligor on $64.1 billion and $54.1 billion (at par value), respectively, of these consolidated obligations. Regulations require each of the FHLBanks to maintain unpledged qualifying assets equal to its participation in the consolidated obligations outstanding. Qualifying assets are defined as cash; secured advances; obligations of or fully guaranteed by the U.S. government; obligations, participations, mortgages, or other instruments of or issued by Fannie Mae or Ginnie Mae; mortgages, obligations or other securities which are or have ever been sold by Freddie Mac under the FHLB Act; and such securities as fiduciary and trust funds may invest in under the laws of the state in which the FHLBank is located. Any assets subject to a lien or pledge for the benefit of holders of any issue of consolidated obligations are treated as if they were free from lien or pledge for purposes of compliance with these regulations. General Terms. Consolidated obligation bonds are issued with either fixed-rate coupon payment terms or variable-rate coupon payment terms that use a variety of indices for interest rate resets such as LIBOR or the federal funds rate. To meet the specific needs of certain investors in consolidated obligations, both fixed-rate bonds and variable-rate bonds may contain complex coupon payment terms and call options. When such consolidated obligations are issued, the Bank generally enters into interest rate exchange agreements containing offsetting features that effectively convert the terms of the bond to those of a simple variable-rate bond. The consolidated obligation bonds typically issued by the Bank, beyond having fixed-rate or simple variable-rate coupon payment terms, may also have the following broad terms regarding either principal repayment or coupon payment terms: Optional principal redemption bonds (callable bonds) may be redeemed in whole or in part at the Bank's discretion on predetermined call dates according to the terms of the bond offerings; Capped floating rate bonds pay interest at variable rates subject to an interest rate ceiling; Step-up bonds pay interest at increasing fixed rates for specified intervals over the life of the bond. These bonds generally contain provisions that enable the Bank to call the bonds at its option on predetermined call dates; Conversion bonds have coupons that convert from fixed to variable, or from variable to fixed, on predetermined dates; Step-down bonds pay interest at decreasing fixed rates for specified intervals over the life of the bond. These bonds generally contain provisions that enable the Bank to call the bonds at its option on predetermined call dates. Interest Rate Payment Terms.

Affordable Housing Program [Abstract] | |
Affordable Housing Program [Text Block] | Affordable Housing Program Section 10(j) of the FHLB Act requires each FHLBank to establish an AHP. Each FHLBank provides subsidies in the form of direct grants and/or below market interest rate advances to members who use the funds to assist with the purchase, construction, or rehabilitation of housing for very low-, low-, and moderate-income households. The Bank provides subsidies under its AHP solely in the form of direct grants. Annually, each FHLBank must set aside for the AHP 10 percent of its current year’s income before charges for AHP (as adjusted for interest expense on mandatorily redeemable capital stock), subject to a collective minimum contribution for all 11 FHLBanks of $100 million . The exclusion of interest expense on mandatorily redeemable capital stock is required pursuant to a Finance Agency regulatory interpretation. If the result of the aggregate 10 percent calculation is less than $100 million for all 11 FHLBanks, then the FHLB Act requires the shortfall to be allocated among the FHLBanks based on the ratio of each FHLBank’s income before AHP to the sum of the income before AHP of all of the FHLBanks provided, however, that each FHLBank’s required annual AHP contribution is limited to its annual net earnings. There was no shortfall during the years ended December 31, 2017 , 2016 or 2015 . If a FHLBank determines that its required contributions are contributing to its financial instability, it may apply to the Finance Agency for a temporary suspension of its AHP contributions. No FHLBank applied for a suspension of its AHP contributions in 2017 , 2016 or 2015 . The Bank’s AHP assessment is derived by adding interest expense on mandatorily redeemable capital stock (see Note 14) to reported income before assessments; the result of this calculation is then multiplied by 10 percent . The Bank charges the amount set aside for AHP to income and recognizes it as a liability. The Bank relieves the AHP liability as members receive AHP grants. If the Bank experiences a loss during a calendar quarter but still has income for the calendar year, the Bank’s obligation to the AHP is based upon its year-to-date income. In years where the Bank’s income before assessments (as adjusted for interest expense on mandatorily redeemable capital stock) is zero or less, the amount of the AHP assessment is typically equal to zero, and the Bank would not typically be entitled to a credit that could be used to reduce required contributions in future years. The following table summarizes the changes in the Bank’s AHP liability during the years ended December 31, 2017, 2016 and 2015 (in thousands): 2017 2016 2015 Balance, beginning of year $ 22,871 $ 22,710 $ 25,998 AHP assessment 16,710 8,831 7,468 Grants funded, net of recaptured amounts (8,335 ) (8,670 ) (10,756 ) Balance, end of year $ 31,246 $ 22,871 $ 22,710 |

Assets and Liabilities Subject to Offsetting [Abstract] | |
Assets and Liabilities Subject to Offsetting [Text Block] | Assets and Liabilities Subject to Offsetting The Bank has derivatives and securities purchased under agreements to resell that are subject to enforceable master netting agreements or similar arrangements. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments (including the right to reclaim cash collateral and the obligation to return cash collateral) where a legally enforceable right of setoff exists. The Bank did not have any liabilities that were eligible to offset its securities purchased under agreements to resell (i.e., securities sold under agreements to repurchase) as of December 31, 2017 or 2016 . The Bank's derivative transactions are executed either bilaterally or, if required, cleared through a third-party central clearinghouse. The Bank has entered into master agreements with each of its bilateral derivative counterparties that provide for the netting of all transactions with each of these counterparties. Under its master agreements with its non-member bilateral derivative counterparties, collateral is delivered (or returned) daily when certain thresholds (ranging from $100,000 to $500,000 ) are met. The Bank offsets the fair value amounts recognized for bilaterally traded derivatives executed with the same counterparty, including any cash collateral remitted to or received from the counterparty. When entering into derivative transactions with its members, the Bank requires the member to post eligible collateral in an amount equal to the sum of the net market value of the member’s derivative transactions with the Bank (if the value is positive to the Bank) plus a percentage of the notional amount of any interest rate swaps, with market values determined on at least a monthly basis. Eligible collateral for derivative transactions with members consists of collateral that is eligible to secure advances and other obligations under the member's Advances and Security Agreement with the Bank. The Bank is not required to pledge collateral to its members to secure derivative positions. For cleared derivatives, all transactions with each clearing member of each clearinghouse are netted pursuant to legally enforceable setoff rights. Cleared derivatives are subject to initial and variation margin requirements established by the clearinghouse and its clearing members. Effective January 3, 2017, one of the Bank's two clearinghouse counterparties made certain amendments to its rulebook that changed the legal characterization of variation margin payments on cleared derivatives to settlements on the contracts. Prior to January 3, 2017, these amounts were characterized as collateral pledged to secure outstanding credit exposure on the derivative contracts. Initial and variation margin (regardless of whether it is characterized as collateral or settlements) is typically delivered/paid (or returned/received) daily and is not subject to any maximum unsecured thresholds. The Bank offsets the fair value amounts recognized for cleared derivatives transacted with each clearing member of each clearinghouse (which fair value amounts include, in the case of one clearinghouse counterparty, variation margin paid or received on daily settled contracts) and any cash collateral pledged or received. The following table presents derivative instruments and securities purchased under agreements to resell with the legal right of offset, including the related collateral received from or pledged to counterparties as of December 31, 2017 and 2016 (in thousands). For daily settled derivative contracts, the variation margin payments/receipts are included in the gross amounts of derivative assets and liabilities.

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Instruments and Hedging Activities Disclosure [Text Block] | Derivatives and Hedging Activities Hedging Activities. As a financial intermediary, the Bank is exposed to interest rate risk. This risk arises from a variety of financial instruments that the Bank enters into on a regular basis in the normal course of its business. The Bank enters into interest rate swap, swaption, cap and forward rate agreements (collectively, interest rate exchange agreements) to manage its exposure to changes in interest rates. The Bank may use these instruments to adjust the effective maturity, repricing frequency, or option characteristics of financial instruments to achieve risk management objectives. In addition, the Bank may use these instruments to hedge the variable cash flows associated with forecasted transactions. The Bank has not entered into any credit default swaps or foreign exchange-related derivatives and, as of December 31, 2017 , it was not a party to any forward rate agreements. The Bank uses interest rate exchange agreements in three ways: (1) by designating the agreement as a fair value hedge of a specific financial instrument or firm commitment; (2) by designating the agreement as a cash flow hedge of a forecasted transaction; or (3) by designating the agreement as a hedge of some other defined risk (referred to as an “economic hedge”). For example, the Bank uses interest rate exchange agreements in its overall interest rate risk management activities to adjust the interest rate sensitivity of consolidated obligations to approximate more closely the interest rate sensitivity of its assets (both advances and investments), and/or to adjust the interest rate sensitivity of advances or investments to approximate more closely the interest rate sensitivity of its liabilities. In addition to using interest rate exchange agreements to manage mismatches between the coupon features of its assets and liabilities, the Bank also uses interest rate exchange agreements to, among other things, manage embedded options in assets and liabilities, to preserve the market value of existing assets and liabilities, to hedge the duration risk of prepayable instruments, to hedge the variable cash flows associated with forecasted transactions, to offset interest rate exchange agreements entered into with members (the Bank serves as an intermediary in these transactions), and to reduce funding costs. The Bank, consistent with Finance Agency regulations, enters into interest rate exchange agreements only to reduce potential market risk exposures inherent in otherwise unhedged assets and liabilities or anticipated transactions, or to act as an intermediary between its members and the Bank’s non-member derivative counterparties. The Bank is not a derivatives dealer and it does not trade derivatives for short-term profit. At inception, the Bank formally documents the relationships between derivatives designated as hedging instruments and their hedged items, its risk management objectives and strategies for undertaking the hedge transactions, and its method for assessing the effectiveness of the hedging relationships. For fair value hedges, this process includes linking the derivatives to: (1) specific assets and liabilities on the statements of condition or (2) firm commitments. For cash flow hedges, this process includes linking the derivatives to forecasted transactions. The Bank also formally assesses (both at the inception of the hedging relationship and on a monthly basis thereafter) whether the derivatives that are used in hedging transactions have been effective in offsetting changes in the fair value of hedged items or the cash flows associated with forecasted transactions and whether those derivatives may be expected to remain effective in future periods. The Bank uses regression analyses to assess the effectiveness of its hedges. Investments — The Bank has invested in agency and non-agency MBS. The interest rate and prepayment risk associated with these investment securities is managed through consolidated obligations and/or derivatives. The Bank may manage prepayment and duration risk presented by some investment securities with either callable or non-callable consolidated obligations or interest rate exchange agreements, including caps and interest rate swaps. A substantial portion of the Bank’s held-to-maturity securities are variable-rate MBS that include caps that would limit the variable-rate coupons if short-term interest rates rise dramatically. To hedge a portion of the potential cap risk embedded in these securities, the Bank has entered into interest rate cap agreements. These derivatives are treated as economic hedges. All of the Bank's available-for-sale securities are fixed-rate agency and other highly rated debentures and agency commercial MBS. To hedge the interest rate risk associated with these fixed-rate investment securities, the Bank has entered into fixed-for-floating interest rate exchange agreements, which are designated as fair value hedges. Advances — The Bank issues both fixed-rate and variable-rate advances. When appropriate, the Bank uses interest rate exchange agreements to adjust the interest rate sensitivity of its fixed-rate advances to approximate more closely the interest rate sensitivity of its liabilities. With issuances of putable advances, the Bank purchases from the member a put option that enables the Bank to terminate a fixed-rate advance on specified future dates. This embedded option is clearly and closely related to the host advance contract. The Bank typically hedges a putable advance by entering into a cancelable interest rate exchange agreement where the Bank pays a fixed-rate coupon and receives a variable-rate coupon, and sells an option to cancel the swap to the swap counterparty. This type of hedge is treated as a fair value hedge. The swap counterparty can cancel the interest rate exchange agreement on the call date and the Bank can cancel the putable advance and offer, subject to certain conditions, replacement funding at prevailing market rates. A small portion of the Bank’s variable-rate advances are subject to interest rate caps that would limit the variable-rate coupons if short-term interest rates rise above a predetermined level. To hedge the cap risk embedded in these advances, the Bank generally enters into interest rate cap agreements. This type of hedge is treated as a fair value hedge. The Bank may hedge a firm commitment for a forward-starting advance through the use of an interest rate swap. In this case, the swap will function as the hedging instrument for both the firm commitment and the subsequent advance. The carrying value of the firm commitment will be included in the basis of the advance at the time the commitment is terminated and the advance is issued. The basis adjustment will then be amortized into interest income over the life of the advance. The Bank enters into optional advance commitments with its members. In an optional advance commitment, the Bank sells an option to the member that provides the member with the right to increase the amount of an existing advance at a specified fixed rate and term on a specified future date, provided the member has satisfied all of the customary requirements for such advance. This embedded option is clearly and closely related to the host contract. The Bank may hedge an optional advance commitment through the use of an interest rate swaption. In this case, the swaption will function as the hedging instrument for both the commitment and, if the option is exercised by the member, the subsequent advance. These swaptions are treated as fair value hedges. Consolidated Obligations - While consolidated obligations are the joint and several obligations of the FHLBanks, each FHLBank is the primary obligor for the consolidated obligations it has issued or assumed from another FHLBank. The Bank generally enters into derivative contracts to hedge the interest rate risk associated with its specific debt issuances. To manage the interest rate risk of certain of its consolidated obligations, the Bank will match the cash outflow on a consolidated obligation with the cash inflow of an interest rate exchange agreement. With issuances of fixed-rate consolidated obligation bonds, the Bank typically enters into a matching interest rate exchange agreement in which the counterparty pays fixed cash flows to the Bank that are designed to mirror in timing and amount the cash outflows the Bank pays on the consolidated obligation. In this transaction, the Bank pays a variable cash flow that closely matches the interest payments it receives on short-term or variable-rate assets, typically one-month or three-month LIBOR. These transactions are treated as fair value hedges. On occasion, the Bank may enter into fixed-for-floating interest rate exchange agreements to hedge the interest rate risk associated with certain of its consolidated obligation discount notes. The derivatives associated with the Bank’s fair value discount note hedging are treated as economic hedges. The Bank may also use interest rate exchange agreements to convert variable-rate consolidated obligation bonds from one index rate (e.g., the daily effective federal funds rate) to another index rate (e.g., one-month or three-month LIBOR). These transactions are treated as economic hedges. The Bank has not issued consolidated obligations denominated in currencies other than U.S. dollars. Forecasted Issuances of Consolidated Obligations — The Bank uses derivatives to hedge the variability of cash flows over a specified period of time as a result of the forecasted issuances and maturities of short-term, fixed-rate instruments, such as three-month consolidated obligation discount notes. Although each short-term consolidated obligation discount note has a fixed rate of interest, a portfolio of rolling consolidated obligation discount notes effectively has a variable interest rate. The variable cash flows associated with these liabilities are converted to fixed-rate cash flows by entering into receive-variable, pay-fixed interest rate swaps. The maturity dates of the cash flow streams are closely matched to the interest rate reset dates of the derivatives. These derivatives are treated as cash flow hedges. Balance Sheet Management — From time to time, the Bank may enter into interest rate basis swaps to reduce its exposure to changing spreads between one-month and three-month LIBOR. In addition, to reduce its exposure to reset risk, the Bank may occasionally enter into forward rate agreements. These derivatives are treated as economic hedges. Intermediation — The Bank offers interest rate swaps, caps and floors to its members to assist them in meeting their hedging needs. In these transactions, the Bank acts as an intermediary for its members by entering into an interest rate exchange agreement with a member and then entering into an offsetting interest rate exchange agreement with one of the Bank’s approved derivative counterparties. All interest rate exchange agreements related to the Bank’s intermediary activities with its members are accounted for as economic hedges. Other — From time to time, the Bank may enter into derivatives to hedge risks to its earnings that are not directly linked to specific assets, liabilities or forecasted transactions. These derivatives are treated as economic hedges. Impact of Derivatives and Hedging Activities.

For the years ended December 31, 2017 , 2016 and 2015 , there were no amounts reclassified from AOCI into earnings as a result of the discontinuance of cash flow hedges because the original forecasted transactions occurred by the end of the originally specified time periods or within two-month periods thereafter. At December 31, 2017 , $185,000 of deferred net gains on derivative instruments in AOCI are expected to be reclassified to earnings during the next 12 months. At December 31, 2017 , the maximum length of time over which the Bank is hedging its exposure to the variability in future cash flows for forecasted transactions is 10 years. Credit Risk Related to Derivatives. The Bank is subject to credit risk due to the risk of nonperformance by counterparties to its derivative agreements. The Bank manages derivative counterparty credit risk through the use of master netting agreements or other similar collateral exchange arrangements, credit analysis, and adherence to the requirements set forth in the Bank’s Enterprise Market Risk Management Policy, Enterprise Credit Risk Management Policy and Finance Agency regulations. The majority of the Bank's derivative transactions have been cleared through third-party central clearinghouses (as of December 31, 2017 , the notional balance of cleared transactions outstanding totaled $25.4 billion ). With cleared transactions, the Bank is exposed to credit risk in the event that the clearinghouse or the clearing member fails to meet its obligations to the Bank. The remainder of the Bank's interest rate exchange agreements have been transacted bilaterally with large financial institutions under master netting agreements or, to a much lesser extent, with member institutions (as of December 31, 2017 , the notional balance of outstanding transactions with non-member bilateral counterparties and member counterparties totaled $11.5 billion and $1.2 billion , respectively). Some of these institutions (or their affiliates) buy, sell, and distribute consolidated obligations. The notional amount of the Bank's interest rate exchange agreements does not reflect its credit risk exposure, which is much less than the notional amount. The Bank's net credit risk exposure is based on the current estimated cost, on a present value basis, of replacing at current market rates all interest rate exchange agreements with individual counterparties, if those counterparties were to default, after taking into account the value of any cash and/or securities collateral held or remitted by the Bank. For counterparties with which the Bank is in a net gain position, the Bank has credit exposure when the collateral it is holding (if any) has a value less than the amount of the gain. For counterparties with which the Bank is in a net loss position, the Bank has credit exposure when it has delivered collateral with a value greater than the amount of the loss position. The net exposure on derivative agreements is presented in Note 12. Based on the netting provisions and collateral requirements associated with its derivative agreements and the creditworthiness of its derivative counterparties, Bank management does not currently anticipate any credit losses on its derivative agreements. |

Capital [Abstract] | |
Stockholders' Equity Note Disclosure [Text Block] | Capital Under the Gramm-Leach-Bliley Act of 1999 (the “GLB Act”) and the Finance Agency’s capital regulations, each FHLBank may issue Class A stock or Class B stock, or both, to its members. The Bank’s Capital Plan provides that it will issue only Class B capital stock. The Class B stock has a par value of $ 100 per share and is purchased, redeemed, repurchased and, with the prior approval of the Bank, transferred only at its par value. As required by statute and regulation, members may request the Bank to redeem excess Class B stock, or withdraw from membership and request the Bank to redeem all outstanding capital stock, with five years’ written notice to the Bank. The regulations also allow the Bank, in its sole discretion, to repurchase members’ excess stock at any time without regard for the five-year notification period as long as the Bank continues to meet its regulatory capital requirements following any stock repurchases, as described below. Members are required to maintain an investment in Class B Stock equal to the sum of a membership investment requirement and an activity-based investment requirement. The membership investment requirement is currently 0.04 percent of each member’s total assets as of the previous calendar year-end, subject to a minimum of $1,000 and a maximum of $7,000,000 . Except as described below, the activity-based investment requirement is (and has been) 4.1 percent of outstanding advances. Members and institutions that acquire members must comply with the activity-based investment requirements for as long as the relevant advances remain outstanding. The Bank’s Board of Directors has the authority to adjust these requirements periodically within ranges established in the Capital Plan, as amended from time to time, to ensure that the Bank remains adequately capitalized. On December 3, 2014, the Bank's Board of Directors adopted several amendments to the Bank’s Capital Plan, subject to approval by the Finance Agency and certain notification requirements. The Finance Agency approved the amendments to the Bank’s Capital Plan on June 1, 2015. Among other things, the Bank’s Capital Plan was amended to allow for the creation of two sub-classes of the Bank’s Class B Stock (Class B-1 Stock and Class B-2 Stock). On August 31, 2015, the Bank gave notice to its shareholders that the amended Capital Plan would be implemented and the two sub-classes of capital stock would be created on October 1, 2015. On October 1, 2015, the Bank exchanged all shares of outstanding Class B Stock at the open of business on that date for an equal number of shares of capital stock consisting of shares of Class B-1 Stock and Class B-2 Stock allocated as described in the next sentence. For each shareholder, (i) a number of shares of existing Class B Stock in an amount sufficient to meet such shareholder’s activity-based investment requirement were exchanged for an equal number of shares of Class B-2 Stock and (ii) all other outstanding shares of existing Class B Stock held by such shareholder were exchanged for an equal number of shares of Class B-1 Stock. Immediately following these exchanges, all shares of previously outstanding Class B Stock were retired. The Capital Plan amendments did not change members' voting rights in any way. For the purpose of voting rights, all shares of Class B Stock, regardless of sub-class, are treated the same. From and after October 1, 2015, Class B-1 Stock is used to meet the membership investment requirement and Class B-2 Stock is used to meet the activity-based investment requirement. Daily, subject to the limitations in the Capital Plan, the Bank converts shares of one sub-class of Class B Stock to the other sub-class of Class B Stock under the following circumstances: (i) shares of Class B-2 Stock held by a shareholder in excess of its activity-based investment requirement are converted into Class B-1 Stock, if necessary, to meet that shareholder’s membership investment requirement and (ii) shares of Class B-1 Stock held by a shareholder in excess of the amount required to meet its membership investment requirement are converted into Class B-2 Stock as needed in order to satisfy that shareholder’s activity-based investment requirement. The Bank also amended its Capital Plan to modify the permissible range for the advances-based component of the activity-based investment requirement. Effective October 1, 2015, the permissible range for the advances-based component of the activity-based investment requirement changed from a range of 3.0 percent to 5.0 percent of members’ advances outstanding to a range of 2.0 percent to 5.0 percent of members’ advances outstanding. The requirement remained at 4.1 percent of members' advances outstanding upon the implementation of the amended Capital Plan. The amendments did not alter the permissible ranges for the membership investment requirement or the Acquired Member Asset component of the activity-based investment requirement and no changes to the then existing requirements were made upon the implementation of the amended Capital Plan. Further, under the amended Capital Plan, the Bank’s Board of Directors may also establish one or more separate advances investment requirement percentages (each an "advance type specific percentage") within the range described above to be applied to a specific category of advances in lieu of the generally applicable advances-related investment requirement percentage in effect at the time. Such category of advances may be defined as a particular advances product offering, advances with particular maturities or other features, advances that represent an increase in member borrowing, or such other criteria as the Bank’s Board of Directors may determine. Any advance type specific percentage may be established for an indefinite period of time, or for a specific time period, at the discretion of the Bank’s Board of Directors. Pursuant to the amended Capital Plan, any changes to the activity-based investment requirement require at least 30 days advance notice to the Bank’s members. On September 21, 2015, the Bank announced a Board-authorized reduction in the activity-based stock investment requirement from 4.1 percent to 2.0 percent for certain advances that were funded during the period from October 21, 2015 through December 31, 2015. To be eligible for the reduced activity-based investment requirement, advances funded during this period had to have a minimum maturity of one year or greater, among other things. The standard activity-based stock investment requirement of 4.1 percent continued to apply to all other advances that were funded during the period from October 21, 2015 through December 31, 2015. All other minimum investment requirements also continued to apply. Excess stock is defined as the amount of stock held by a member (or former member) in excess of that institution’s minimum investment requirement (i.e., the amount of stock held in excess of its activity-based investment requirement and, in the case of a member, its membership investment requirement). From and after October 1, 2015, all excess stock is held as Class B-1 Stock at all times. At any time, shareholders may request the Bank to repurchase excess capital stock. Although the Bank is not obligated to repurchase excess stock prior to the expiration of a five-year redemption or withdrawal notification period, it will typically endeavor to honor such requests within a reasonable period of time (generally not exceeding 30 days) so long as the Bank will continue to meet its regulatory capital requirements following the repurchase. The Bank’s Member Products and Credit Policy provides that the Bank may periodically repurchase a portion of members’ excess capital stock. The Bank generally repurchases surplus stock quarterly. For the repurchases that occurred during 2017 and 2016, surplus stock was defined as the amount of stock held by a shareholder in excess of 125 percent of the shareholder’s minimum investment requirement. For those repurchases, a shareholder's surplus stock was not repurchased if: (1) the amount of that shareholder's surplus stock was $2,500,000 or less, (2) the shareholder elected to opt out of the repurchase, or (3) the shareholder was on restricted collateral status (subject to certain exceptions). For the repurchases that occurred between January 30, 2015 and August 7, 2015, surplus stock was defined as the amount of stock held by a shareholder in excess of 102.5 percent of the shareholder’s minimum investment requirement. For the repurchases that occurred between January 30, 2015 and August 7, 2015, a shareholder's surplus stock was not repurchased if the amount of that shareholder's surplus stock was $100,000 or less or if, subject to certain exceptions, the shareholder was on restricted collateral status. For the repurchase that occurred on November 6, 2015, surplus stock was defined as the amount of stock held by a shareholder in excess of 120 percent of the shareholder’s minimum investment requirement. For the repurchase that occurred on November 6, 2015, a shareholder's surplus stock was not repurchased if the amount of that shareholder's surplus stock was $1,000,000 or less or if, subject to certain exceptions, the shareholder was on restricted collateral status. For each of the repurchases that occurred in 2015, shareholders were also given the opportunity to opt-out of the repurchase if they chose to do so. During the years ended December 31, 2017, 2016 and 2015 , the Bank repurchased surplus stock totaling $423,322,000 , $312,647,000 , and $574,896,000 , respectively, none of which was classified as mandatorily redeemable capital stock at the time of repurchase. From time to time, the Bank may further modify the definition of surplus stock or the timing and/or frequency of surplus stock repurchases. The following table presents total excess stock at December 31, 2017 and 2016 (in thousands). 2017 2016 Excess stock Capital stock $ 545,630 $ 396,167 Mandatorily redeemable capital stock 5,096 1,602 Total $ 550,726 $ 397,769 Under the Finance Agency’s regulations, the Bank is subject to three capital requirements. First, the Bank must maintain at all times permanent capital (defined under the Finance Agency’s rules and regulations as retained earnings and all Class B stock regardless of its classification for financial reporting purposes) in an amount at least equal to its risk-based capital requirement, which is the sum of its credit risk capital requirement, its market risk capital requirement, and its operations risk capital requirement, calculated in accordance with the rules and regulations of the Finance Agency. The Finance Agency may require the Bank to maintain a greater amount of permanent capital than is required by the risk-based capital requirements as defined. Second, the Bank must, at all times, maintain total capital in an amount at least equal to 4.0 percent of its total assets (capital-to-assets ratio). For the Bank, total capital is defined by Finance Agency rules and regulations as the Bank’s permanent capital and the amount of any general allowance for losses (i.e., those reserves that are not held against specific assets). Finally, the Bank is required to maintain at all times a minimum leverage capital-to-assets ratio in an amount at least equal to 5.0 percent of its total assets. In applying this requirement to the Bank, leverage capital includes the Bank’s permanent capital multiplied by a factor of 1.5 plus the amount of any general allowance for losses. The Bank did not have any general reserves at December 31, 2017 or 2016 . Under the regulatory definitions, total capital and permanent capital exclude AOCI. Additionally, mandatorily redeemable capital stock is considered capital for purposes of determining the Bank’s compliance with its regulatory capital requirements. At all times during the three years ended December 31, 2017 , the Bank was in compliance with the aforementioned capital requirements. The following table summarizes the Bank’s compliance with the Finance Agency’s capital requirements as of December 31, 2017 and 2016 (dollars in thousands): December 31, 2017 December 31, 2016 Required Actual Required Actual Regulatory capital requirements: Risk-based capital $ 831,553 $ 3,265,641 $ 683,690 $ 2,757,549 Total capital $ 2,740,972 $ 3,265,641 $ 2,328,483 $ 2,757,549 Total capital-to-assets ratio 4.00 % 4.77 % 4.00 % 4.74 % Leverage capital $ 3,426,215 $ 4,898,462 $ 2,910,604 $ 4,136,324 Leverage capital-to-assets ratio 5.00 % 7.15 % 5.00 % 7.11 % On August 4, 2009, the Finance Agency adopted a final rule establishing capital classifications and critical capital levels for the FHLBanks. The rule defines critical capital levels for the FHLBanks and establishes criteria for each of the following capital classifications identified in the Safety and Soundness Act, as amended by the Housing and Economic Recovery Act of 2008: adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. An adequately capitalized FHLBank meets all existing risk-based and minimum capital requirements. An undercapitalized FHLBank does not meet one or more of its risk-based or minimum capital requirements, but nonetheless has total capital equal to or greater than 75 percent of all capital requirements. A significantly undercapitalized FHLBank does not have total capital equal to or greater than 75 percent of all capital requirements, but the FHLBank does have total capital greater than 2 percent of its total assets. A critically undercapitalized FHLBank has total capital that is less than or equal to 2 percent of its total assets. The Bank has been classified as adequately capitalized since the rule became effective. In addition to restrictions on capital distributions by a FHLBank that does not meet all of its risk-based and minimum capital requirements, a FHLBank that is classified as undercapitalized, significantly undercapitalized or critically undercapitalized is required to take certain actions, such as submitting a capital restoration plan to the Director of the Finance Agency for approval. Additionally, with respect to a FHLBank that is less than adequately capitalized, the Director of the Finance Agency may take other actions that he or she determines will help ensure the safe and sound operation of the FHLBank and its compliance with its risk-based and minimum capital requirements in a reasonable period of time. The GLB Act made membership voluntary for all members. Members that withdraw from membership may not be readmitted to membership in any FHLBank for at least five years following the date that their membership was terminated and all of their shares of stock were redeemed or repurchased. Effective February 28, 2011, the Bank entered into a Joint Capital Enhancement Agreement (the “JCE Agreement”) with the other FHLBanks. Effective August 5, 2011, the FHLBanks amended the JCE Agreement, and the Finance Agency approved an amendment to the Bank's capital plan to incorporate its provisions on that same date. The amended JCE Agreement provides that the Bank (and each of the other FHLBanks) will, on a quarterly basis, allocate at least 20 percent of its net income to a restricted retained earnings account (“RRE Account”). Pursuant to the provisions of the amended JCE Agreement, the Bank is required to build its RRE Account to an amount equal to one percent of its total outstanding consolidated obligations, which for this purpose is based on the most recent quarter’s average carrying value of all outstanding consolidated obligations, excluding hedging adjustments. Amounts allocated to the Bank’s RRE Account are not available to pay dividends. The Bank’s Board of Directors may declare dividends at the same rate for all shares of Class B Stock, or at different rates for Class B-1 Stock and Class B-2 Stock, provided that in no event can the dividend rate on Class B-2 Stock be lower than the dividend rate on Class B-1 Stock. Dividend payments may be made in the form of cash, additional shares of either, or both, sub-classes of Class B Stock, or a combination thereof as determined by the Bank’s Board of Directors and can be paid only from unrestricted retained earnings or a portion of current earnings. The Bank’s Board of Directors may not declare or pay a dividend if the Bank is not in compliance with its minimum capital requirements or if the Bank would fail to meet its minimum capital requirements after paying such dividend. In addition, the Bank’s Board of Directors may not declare or pay a dividend based on projected or anticipated earnings; further, the Bank may not declare or pay any dividends in the form of capital stock if its excess stock is greater than 1 percent of its total assets or if, after the issuance of such shares, the Bank’s outstanding excess stock would be greater than 1 percent of its total assets. Mandatorily Redeemable Capital Stock. As discussed in Note 1, the Bank’s capital stock is classified as equity (capital) for financial reporting purposes until either a written redemption or withdrawal notice is received from a member or a membership withdrawal or termination is otherwise initiated, at which time the capital stock is reclassified to liabilities. The Finance Agency has confirmed that the accounting classification of certain shares of its capital stock as liabilities does not affect the definition of capital for purposes of determining the Bank’s compliance with its regulatory capital requirements. At December 31, 2017 , the Bank had $5,941,000 in outstanding capital stock subject to mandatory redemption held by 15 institutions. As of December 31, 2016 , the Bank had $3,417,000 in outstanding capital stock subject to mandatory redemption held by 15 institutions. These amounts are classified as liabilities in the statements of condition. During the years ended December 31, 2017, 2016 and 2015 , dividends on mandatorily redeemable capital stock in the amount of $107,000 , $30,000 and $16,000 , respectively, were recorded as interest expense in the statements of income. The Bank is not required to redeem or repurchase activity-based stock until the later of the expiration of a notice of redemption or withdrawal or the date the activity no longer remains outstanding. If activity-based stock becomes excess stock as a result of reduced activity, the Bank, in its discretion and subject to certain regulatory restrictions, may repurchase excess stock prior to the expiration of the notice of redemption or withdrawal. The Bank will generally repurchase such excess stock as long as it expects to continue to meet its minimum capital requirements following the repurchase. The following table summarizes the Bank’s mandatorily redeemable capital stock at December 31, 2017 by year of earliest mandatory redemption (in thousands). The earliest mandatory redemption reflects the earliest time at which the Bank is required to redeem the shareholder’s capital stock, and is based on the assumption that the activities associated with the activity-based stock have concluded by the time the notice of redemption or withdrawal expires. 2018 $ 1,359 2019 4 2020 4 2021 1,158 2022 3,416 Total $ 5,941 The following table summarizes the Bank’s mandatorily redeemable capital stock activity during 2017 , 2016 and 2015 (in thousands).

A member that cancels a stock redemption or withdrawal notice more than 30 days after it is received by the Bank and prior to its expiration is subject to a cancellation fee equal to a percentage of the par value of the capital stock subject to the cancellation notice. The following table provides the number of institutions that held mandatorily redeemable capital stock and the number that submitted a withdrawal notice or otherwise initiated a termination of their membership and the number of terminations completed during 2017 , 2016 and 2015 : 2017 2016 2015 Number of institutions, beginning of year 15 16 18 Due to mergers and acquisitions 2 4 7 Due to withdrawals 1 — — Due to liquidation 1 — — Terminations completed during the year (4 ) (5 ) (9 ) Number of institutions, end of year 15 15 16 The Bank did not receive any stock redemption notices in 2017 , 2016 or 2015 . Limitations on Redemption or Repurchase of Capital Stock. The GLB Act imposes the following restrictions on the redemption or repurchase of the Bank’s capital stock. • In no event may the Bank redeem or repurchase capital stock if the Bank is not in compliance with its minimum capital requirements or if the redemption or repurchase would cause the Bank to be out of compliance with its minimum capital requirements, or if the redemption or repurchase would cause the member to be out of compliance with its minimum investment requirement. In addition, the Bank’s Board of Directors may suspend redemption of capital stock if the Bank reasonably believes that continued redemption of capital stock would cause the Bank to fail to meet its minimum capital requirements in the future, would prevent the Bank from maintaining adequate capital against a potential risk that may not be adequately reflected in its minimum capital requirements, or would otherwise prevent the Bank from operating in a safe and sound manner. • In no event may the Bank redeem or repurchase capital stock without the prior written approval of the Finance Agency if the Finance Agency or the Bank’s Board of Directors has determined that the Bank has incurred, or is likely to incur, losses that result in, or are likely to result in, charges against the capital of the Bank. For this purpose, charges against the capital of the Bank means an other than temporary decline in the Bank’s total equity that causes the value of total equity to fall below the Bank’s aggregate capital stock amount. Such a determination may be made by the Finance Agency or the Board of Directors even if the Bank is in compliance with its minimum capital requirements. • The Bank may not repurchase any capital stock without the written consent of the Finance Agency during any period in which the Bank has suspended redemptions of capital stock. The Bank is required to notify the Finance Agency if it suspends redemptions of capital stock and set forth its plan for addressing the conditions that led to the suspension. The Finance Agency may require the Bank to reinstate redemptions of capital stock. • In no event may the Bank redeem or repurchase shares of capital stock if the principal and interest due on any FHLBank System consolidated obligations issued through the Office of Finance have not been paid in full or, under certain circumstances, if the Bank becomes a non-complying FHLBank under Finance Agency regulations as a result of its inability to comply with regulatory liquidity requirements or to satisfy its current obligations. • If at any time the Bank determines that the total amount of capital stock subject to outstanding stock redemption or withdrawal notices with expiration dates within the following 12 months exceeds the amount of capital stock the Bank could redeem and still comply with its minimum capital requirements, the Bank will determine whether to suspend redemption and repurchase activities altogether, to fulfill requests for redemption sequentially in the order in which they were received, to fulfill the requests on a pro rata basis, or to take other action deemed appropriate by the Bank. |

Employee Retirement Plans [Abstract] | |
Pension and Other Postretirement Benefits Disclosure [Text Block] | Employee Retirement Plans The Bank participates in the Pentegra Defined Benefit Plan for Financial Institutions (“Pentegra DB Plan”), a tax-qualified defined benefit pension plan. The Pentegra DB Plan covers substantially all officers and employees of the Bank who were hired prior to January 1, 2007, and any new employee of the Bank who was hired on or after January 1, 2007, provided that the employee had prior service with a financial services institution that participated in the Pentegra DB Plan, during which service the employee was covered by such plan. In addition, effective July 1, 2015, coverage was extended to include all of the Bank's non-highly compensated employees (as defined by Internal Revenue Service rules) who were hired on and after January 1, 2007 but before August 1, 2010. The Pentegra DB Plan is treated as a multiemployer plan for accounting purposes, but operates as a multiple-employer plan under the Employee Retirement Income Security Act of 1974 ("ERISA") and the Internal Revenue Code. As a result, certain multiemployer plan disclosures, including the certified zone status, are not applicable to the Pentegra DB Plan. Under the Pentegra DB Plan, contributions made by a participating employer may be used to provide benefits to employees of other participating employers because assets contributed by an employer are not segregated in a separate account or restricted to provide benefits only to employees of that employer. In addition, in the event a participating employer is unable to meet its contribution requirements, the required contributions for the other participating employers could increase proportionately. The Pentegra DB Plan operates on a fiscal year from July 1 through June 30. The Pentegra DB Plan files one Form 5500 on behalf of all employers who participate in the plan. The Employer Identification Number is 13-5645888 and the three-digit plan number is 333 . There are no collective bargaining agreements in place at the Bank. The Pentegra DB Plan's annual valuation process includes separate calculations of the plan's funded status as well as the funded status of each participating employer. Participating employers in an under-funded position are billed for their required contributions while those in an over-funded position can use their surplus to offset all or a portion of their contribution requirement. The funded status is defined as the market value of assets divided by the funding target (an amount equal to 100 percent of the present value of all benefit liabilities accrued at the valuation date) and is calculated as of the beginning of the Pentegra DB Plan year. As permitted by ERISA, the Pentegra DB Plan accepts contributions for a plan year up to eight and a half months after the end of that plan year and, as a result, the market value of assets at the valuation date (July 1) is increased by any subsequent contributions that are designated for the immediately preceding plan year ended June 30. The most recent Form 5500 available for the Pentegra DB Plan is for the year ended June 30, 2016 . For the plan years ended June 30, 2016 and 2015 , the Bank's contributions did not represent more than 5 percent of the total contributions to the plan. The following table presents the Bank's net pension cost and its funded status, as well as the funded status of the Pentegra DB Plan (dollars in thousands, including amounts presented in the footnotes to the table). 2017 2016 2015 Net pension cost charged to compensation and benefit expense for the year ended December 31 $ 5,214 $ 4,518 $ 2,187 Pentegra DB Plan funded status as of July 1 111.3 % (a) 104.7 % (b) 107.0 % Bank's funded status as of July 1 97.4 % 93.8 % 95.1 % ____________ (a) The Pentegra DB Plan's funded status as of July 1, 2017 is preliminary and may increase because the plan's participants were permitted to make contributions for the plan year ended June 30, 2017 through March 15, 2018 . Contributions made during the period from July 1, 2017 through March 15, 2018 and designated for the plan year ended June 30, 2017 will be included in the final valuation as of July 1, 2017 . The final funded status as of July 1, 2017 will not be available until the Form 5500 for the plan year July 1, 2017 through June 30, 2018 is filed (this Form 5500 is due to be filed no later than April 2019 ). (b) The Pentegra DB Plan's funded status as of July 1, 2016 is preliminary and may increase because the plan's participants were permitted to make contributions for the plan year ended June 30, 2016 through March 15, 2017 . Contributions made during the period from July 1, 2016 through March 15, 2017 and designated for the plan year ended June 30, 2016 will be included in the final valuation as of July 1, 2016 . The final funded status as of July 1, 2016 will not be available until the Form 5500 for the plan year July 1, 2016 through June 30, 2017 is filed (this Form 5500 is due to be filed no later than April 2018 ). The Bank also participates in the Pentegra Defined Contribution Plan for Financial Institutions (“Pentegra DC Plan”), a tax-qualified defined contribution plan. The Bank’s contributions to the Pentegra DC Plan are equal to a percentage of voluntary employee contributions, subject to certain limitations. During the years ended December 31, 2017, 2016 and 2015 , the Bank contributed $1,411,000 , $1,355,000 and $1,257,000 , respectively, to the Pentegra DC Plan. Additionally, the Bank maintains a non-qualified deferred compensation plan that is available to some employees, which is, in substance, an unfunded supplemental retirement plan. The Bank’s liability, which consists of the accumulated employee compensation deferrals, accrued earnings (or losses) on those deferrals and matching Bank contributions corresponding to the contribution percentages applicable to the defined contribution plan, was $4,377,000 and $3,341,000 at December 31, 2017 and 2016 , respectively. Compensation and benefits expense includes accrued earnings on deferred employee compensation and Bank contributions totaling $585,000 , $302,000 and $46,000 for the years ended December 31, 2017, 2016 and 2015 , respectively. The Bank's non-qualified deferred compensation plan is also available to all of its directors. The Bank’s liability for directors' deferred compensation, which consists of the accumulated compensation deferrals (representing directors’ fees) and the accrued earnings (losses) on those deferrals, was $2,334,000 and $1,842,000 at December 31, 2017 and 2016 , respectively. The Bank maintains a Special Non-Qualified Deferred Compensation Plan (the “Plan”), a defined contribution plan that was established primarily to provide supplemental retirement benefits to those employees who were serving as the Bank’s executive officers at the time the Plan was established. Each participant’s benefit under the Plan consists of contributions that were made by the Bank on the participant’s behalf, plus an allocation of the investment gains or losses on the assets used to fund the Plan. Contributions to the Plan are determined solely at the discretion of the Bank’s Board of Directors; the Bank has no obligation or current intention to make future contributions to the Plan. The Bank’s accrued liability under this plan was $5,322,000 and $4,894,000 at December 31, 2017 and 2016 , respectively. The Bank did not make any contributions to the Plan during the years ended December 31, 2017, 2016 or 2015. The Bank sponsors a retirement benefits program that includes health care and life insurance benefits for eligible retirees. The health care portion of the program is contributory while the life insurance benefits, which are available to retirees with at least 20 years of service, are offered on a noncontributory basis. Prior to January 1, 2005, retirees were eligible to remain enrolled in the Bank’s health care benefits plan if age 50 or older with at least 10 years of service at the time of retirement. In December 2004, the Bank modified the eligibility requirements relating to retiree health care continuation benefits. Effective January 1, 2005, retirees are eligible to remain enrolled in the Bank’s health care benefits plan if age 55 or older with at least 15 years of service at the time of retirement. Employees who were age 50 or older with 10 years of service and those who had 20 years of service as of December 31, 2004 were not subject to the revised eligibility requirements. Additionally, then current retiree benefits were unaffected by these modifications. In October 2005, the Bank modified the participant contribution requirements relating to its retirement benefits program. Effective December 31, 2005, retirees who are age 55 or older with at least 15 years of service at the time of retirement can remain enrolled in the Bank’s health care benefits program by paying 100% of the expected plan cost. Previously, participant contributions were subsidized by the Bank; this subsidy was based upon the Bank’s COBRA premium rate and the employee’s age and length of service with the Bank. Then current retirees, employees who were hired prior to January 1, 1991 and those who, as of December 31, 2004, had at least 20 years of service or were age 50 or older with 10 years of service are not subject to these revised contribution requirements prior to age 65. Under the revised plan, at age 65, all plan participants are required to pay 100% of the expected plan cost. The Bank does not have any plan assets set aside for the retirement benefits program. The Bank uses a December 31 measurement date for its retirement benefits program. A reconciliation of the accumulated postretirement benefit obligation (“APBO”) and funding status of the retirement benefits program for the years ended December 31, 2017 and 2016 is as follows (in thousands): Year Ended December 31, 2017 2016 Change in APBO APBO at beginning of year $ 838 $ 1,044 Service cost 25 23 Interest cost 19 28 Actuarial gain (204 ) (8 ) Participant contributions 178 167 Benefits paid (306 ) (416 ) APBO at end of year 550 838 Change in plan assets Fair value of plan assets at beginning of year — — Benefits paid by the Bank 128 249 Participant contributions 178 167 Benefits paid (306 ) (416 ) Fair value of plan assets at end of year — — Funded status recognized in other liabilities at end of year $ (550 ) $ (838 ) Amounts recognized in AOCI at December 31, 2017 and 2016 consist of the following (in thousands): December 31, 2017 2016 Net actuarial gain $ 1,646 $ 1,549 Prior service cost (129 ) (149 ) $ 1,517 $ 1,400 The amounts in AOCI include $20,000 of prior service cost and $106,000 of net actuarial gains that are expected to be recognized as components of net periodic benefit cost in 2018 . The actuarial assumptions used in the measurement of the Bank’s benefit obligation included a gross health care cost trend rate of 6.6 percent for 2018 . For 2017 , 2016 and 2015 , gross health care cost trend rates of 7.6 percent, 6.7 percent and 7.8 percent, respectively, were used. The gross health care cost trend rate is assumed to decline by 0.03 percent per year to a final rate of 4.4 percent in 2095 and thereafter. To compute the APBO at December 31, 2017 and 2016 , weighted average discount rates of 3.74 percent and 3.12 percent were used. Weighted average discount rates of 3.12 percent, 3.08 percent and 3.44 percent were used to compute the net periodic benefit cost for 2017 , 2016 and 2015 , respectively. Components of net periodic benefit cost (credit) for the years ended December 31, 2017, 2016 and 2015 were as follows (in thousands): Year Ended December 31, 2017 2016 2015 Service cost $ 25 $ 23 $ 19 Interest cost 19 28 46 Amortization of prior service cost 20 20 8 Amortization of net actuarial gain (107 ) (106 ) (88 ) Net periodic benefit credit $ (43 ) $ (35 ) $ (15 ) Under U.S. GAAP, the Bank is required to recognize the overfunded or underfunded status of its retirement benefits program as an asset or liability in its statement of condition and to recognize changes in that funded status in the year in which the changes occur through other comprehensive income. Changes in benefit obligations recognized in other comprehensive income during the years ended December 31, 2017, 2016 and 2015 were as follows (in thousands): Year Ended December 31, 2017 2016 2015 Amortization of prior service cost included in net periodic benefit cost $ 20 $ 20 $ 8 Actuarial gain 204 8 222 Amortization of net actuarial gain included in net periodic benefit cost (107 ) (106 ) (88 ) Total changes in benefit obligations recognized in other comprehensive income $ 117 $ (78 ) $ 142 A 1 percent increase in the health care cost trend rate would have reduced the APBO at December 31, 2017 by $93,000 and the aggregate of the service and interest cost components of the net periodic benefit cost for the year ended December 31, 2017 by $12,000 . Alternatively, a 1 percent decrease in the health care cost trend rate would have increased the APBO at December 31, 2017 by $129,000 and the aggregate of the service and interest cost components of the net periodic benefit cost for the year ended December 31, 2017 by $18,000 . The following net postretirement benefit payments, which reflect expected future service, as appropriate, are expected to be paid (in thousands): Year Ended December 31, Expected Benefits Payments, Net of Participant Contributions 2018 $ 121 2019 124 2020 93 2021 85 2022 90 2023-2027 28 $ 541 |

Fair Value Disclosures [Abstract] | |
Fair Value Disclosures [Text Block] | Estimated Fair Values Fair value is defined under U.S. GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. U.S. GAAP establishes a fair value hierarchy and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. U.S. GAAP also requires an entity to disclose the level within the fair value hierarchy in which each measurement is classified. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels: Level 1 Inputs — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2 Inputs — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active or in which little information is released publicly; (3) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data (e.g., implied spreads). Level 3 Inputs — Unobservable inputs for the asset or liability that are supported by little or no market activity. None of the Bank’s assets or liabilities that are recorded at fair value on a recurring basis were measured using significant Level 3 inputs. For financial instruments carried at fair value, the Bank reviews the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain assets or liabilities. Reclassifications, if any, would be reported as transfers as of the beginning of the quarter in which the changes occurred. For the years ended December 31, 2017 and 2016 , the Bank did not reclassify any fair value measurements. The following estimated fair value amounts have been determined by the Bank using available market information and the Bank’s best judgment of appropriate valuation methods. These estimates are based on pertinent information available to the Bank as of December 31, 2017 and 2016 . Although the Bank uses its best judgment in estimating the fair value of these financial instruments, there are inherent limitations in any estimation technique or valuation methodology. For example, because an active secondary market does not exist for many of the Bank’s financial instruments (e.g., advances, non-agency RMBS and mortgage loans held for portfolio), in certain cases their fair values are not subject to precise quantification or verification. Therefore, the estimated fair values presented below in the Fair Value Summary Tables may not be indicative of the amounts that would have been realized in market transactions at the reporting dates. Further, the fair values do not represent an estimate of the overall market value of the Bank as a going concern, which would take into account future business opportunities. The valuation techniques used to measure the fair values of the Bank’s financial instruments are described below. Cash and due from banks. The estimated fair value equals the carrying value. Interest-bearing deposit assets. Interest-bearing deposit assets earn interest at floating market rates; therefore, the estimated fair value of the deposits approximates their carrying value. Securities purchased under agreements to resell, federal funds sold and loans to other FHLBanks. All federal funds sold, securities purchased under agreements to resell and loans to other FHLBanks represent overnight balances. The estimated fair values approximate the carrying values. Trading, available-for-sale and held-to-maturity securities. To value its U.S. Treasury Note classified as a trading security, all of its available-for-sale securities, and its held-to-maturity MBS holdings and state housing agency debentures, the Bank obtains prices from three designated third-party pricing vendors when available. The pricing vendors use various proprietary models to price these securities. The inputs to those models are derived from various sources including, but not limited to, benchmark yields, reported trades, dealer estimates, issuer spreads, benchmark securities, bids, offers and other market-related data. Because many securities do not trade on a daily basis, the pricing vendors use available information as applicable such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to determine the prices for individual securities. Each pricing vendor has an established challenge process in place for all security valuations, which facilitates resolution of potentially erroneous prices identified by the Bank. Recently, the Bank conducted reviews of the three pricing vendors to reconfirm its understanding of the vendors' pricing processes, methodologies and control procedures and was satisfied that those processes, methodologies and control procedures were adequate and appropriate. A “median” price is first established for each security using a formula that is based upon the number of prices received. If three prices are received, the middle price is the median price; if two prices are received, the average of the two prices is the median price; and if one price is received, it is the median price (and also the final price) subject to some type of validation similar to the evaluation of outliers described below. All prices that are within a specified tolerance threshold of the median price are included in the “cluster” of prices that are averaged to compute a “default” price. All prices that are outside the threshold (“outliers”) are subject to further analysis (including, but not limited to, comparison to prices provided by an additional third-party valuation service, prices for similar securities, and/or non-binding dealer estimates) to determine if an outlier is a better estimate of fair value. If an outlier (or some other price identified in the analysis) is determined to be a better estimate of fair value, then the outlier (or the other price, as appropriate) is used as the final price rather than the default price. If, on the other hand, the analysis confirms that an outlier (or outliers) is (are) in fact not representative of fair value and the default price is the best estimate, then the default price is used as the final price. In all cases, the final price is used to determine the fair value of the security. If all prices received for a security are outside the tolerance threshold level of the median price, then there is no default price, and the final price is determined by an evaluation of all outlier prices as described above. As of December 31, 2017 and 2016 , three vendor prices were received for substantially all of the Bank's trading, available-for-sale and held-to-maturity securities referred to above and the final prices for substantially all of those securities were computed by averaging the three prices. Based on the Bank's understanding of the pricing methods employed by the third-party pricing vendors and the relative lack of dispersion among the vendor prices (or, in those instances in which there were outliers, the Bank's additional analyses), the Bank believes its final prices result in reasonable estimates of the fair values and that the fair value measurements are classified appropriately in the fair value hierarchy. The Bank estimates the fair values of its held-to-maturity government-guaranteed debentures using a pricing model and observable market data (i.e., the U.S. Government Agency Fair Value curve and, for debentures containing call features, swaption volatility). To value its mutual fund investments classified as trading securities, the Bank obtains quoted prices for the mutual funds. Advances. The Bank determines the estimated fair values of advances by calculating the present value of expected future cash flows from the advances using the replacement advance rates for advances with similar terms and, for advances containing options, swaption volatility. This amount is then reduced for accrued interest receivable. Each FHLBank prices advances at a spread to its cost of funds. Each FHLBank's cost of funds approximates the "CO curve," which is derived by adding to the U.S. Treasury curve indicative spreads obtained from market-observable sources. The indicative spreads are generally derived from dealer pricing indications, recent trades, secondary market activity and historical pricing relationships. Mortgage loans held for portfolio. The Bank estimates the fair values of mortgage loans held for portfolio based upon the prices for to-be-announced ("TBA") securities, which represent quoted market prices for forward settling agency MBS. The prices are adjusted for differences in coupon, cost to carry, vintage, remittance type and product type between the Bank's mortgage loans and the referenced TBA MBS. The prices of the referenced TBA MBS and the Bank's mortgage loans are highly dependent upon current mortgage rates and the market's expectations of future mortgage rates and prepayments. Accrued interest receivable and payable. The estimated fair value of accrued interest receivable and payable approximates the carrying value due to their short-term nature. Derivative assets/liabilities . The fair values of the Bank’s interest rate swap and swaption agreements are estimated using a pricing model with inputs that are observable in the market (e.g., the relevant interest rate curves (that is, the relevant LIBOR swap curve and, for purposes of discounting, the overnight index swap ("OIS") curve) and, for agreements containing options, swaption volatility). The fair values of the Bank’s interest rate caps are also estimated using a pricing model with inputs that are observable in the market (that is, cap volatility, the relevant LIBOR swap curve and, for purposes of discounting, the OIS curve). As the collateral (or variation margin in the case of daily settled contracts) and netting provisions of the Bank’s arrangements with its derivative counterparties significantly reduce the risk from nonperformance (see Note 12), the Bank does not consider its own nonperformance risk or the nonperformance risk associated with each of its counterparties to be a significant factor in the valuation of its derivative assets and liabilities. The Bank compares the fair values obtained from its pricing model to clearinghouse valuations (in the case of cleared derivatives) and non-binding dealer estimates (in the case of bilateral derivatives) and may also compare its fair values to those of similar instruments to ensure that the fair values are reasonable. The fair values of the Bank’s derivative assets and liabilities include accrued interest receivable/payable and cash collateral remitted to/received from counterparties; the estimated fair values of the accrued interest receivable/payable and cash collateral approximate their carrying values due to their short-term nature. The fair values of the Bank's bilateral derivatives are netted by counterparty pursuant to the provisions of the credit support annexes to the Bank’s master netting agreements with its non-member bilateral derivative counterparties. The Bank's cleared derivative transactions with each clearing member of each clearinghouse are netted pursuant to the Bank's arrangements with those parties. In each case, if the netted amounts are positive, they are classified as an asset and, if negative, as a liability. The fair values of the Bank's mortgage delivery commitments are estimated in a manner similar to the method used to value the Bank's mortgage loans held for portfolio. Deposit liabilities. The Bank determines the estimated fair values of its deposit liabilities with fixed rates and more than three months to maturity by calculating the present value of expected future cash flows from the deposits and reducing this amount for accrued interest payable. The discount rates used in these calculations are based on replacement funding rates for liabilities with similar terms. The estimated fair value approximates the carrying value for deposits with variable rates and fixed rates with three months or less to their maturity or repricing date. Consolidated obligations. The Bank estimates the fair values of consolidated obligations by calculating the present value of expected future cash flows using discount rates that are based on replacement funding rates for liabilities with similar terms and reducing this amount for accrued interest payable. Prior to April 2017, the Bank used as inputs to the valuation for all consolidated obligations the CO curve and, for consolidated obligations containing options, swaption volatility. In April 2017, the Bank refined its method for estimating the fair values of callable consolidated obligation bonds. To value its callable bonds, the Bank began using the LIBOR swap curve minus (or plus) a spread and swaption volatility. This refinement did not have a significant impact on the estimated fair value of the Bank's aggregate portfolio of consolidated obligation bonds at the time it was implemented. Mandatorily redeemable capital stock. The fair value of capital stock subject to mandatory redemption is generally equal to its par value ($100 per share), as adjusted for any estimated dividend earned but unpaid at the time of reclassification from equity to liabilities. The Bank’s capital stock cannot, by statute or implementing regulation, be purchased, redeemed, repurchased or transferred at any amount other than its par value. Commitments. The estimated fair value of the Bank’s commitments to extend credit, including advances and letters of credit, and to purchase mortgage loans was not material at December 31, 2017 or 2016 . In May 2015, the Bank replaced its third-party pricing/risk model with a new third-party pricing/risk model. Among other things, the third-party pricing/risk model is used to estimate the fair values of the Bank's interest rate exchange agreements, advances, consolidated obligations, term deposits and held-to-maturity debentures. In addition, this model is used to calculate the periodic changes in the fair values of hedged items (e.g., certain advances, available-for-sale securities and consolidated obligations) that are attributable to changes in LIBOR, the designated benchmark interest rate ("the benchmark fair values") and, beginning in September 2015, the periodic changes in the fair values of hypothetical derivatives associated with cash flow hedges. The implementation of the new model did not have a significant impact on the estimated fair values and, where applicable, the benchmark fair values of the financial instruments referred to above. On the date the new model was implemented, there was an increase of approximately $3,100,000 in the computed amount of the Bank's net hedge ineffectiveness gains (including both fair value and economic hedges) relating to the Bank's entire derivatives portfolio. The derivatives portfolio approximated $30.4 billion (notional balance) at that time. The following table presents the carrying values and estimated fair values of the Bank’s financial instruments at December 31, 2017 (in thousands), as well as the level within the fair value hierarchy in which the measurements are classified. Financial assets and liabilities are classified in their entirety based on the lowest level input that is significant to the fair value estimate.

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies Disclosure [Text Block] | Commitments and Contingencies Joint and several liability. As described in Note 10, the Bank is jointly and severally liable with the other 10 FHLBanks for the payment of principal and interest on all of the consolidated obligations issued by the FHLBanks. At December 31, 2017 and 2016 , the par amounts of the other 10 FHLBanks’ outstanding consolidated obligations totaled $970 billion and $935 billion , respectively. The Finance Agency, in its discretion, may require any FHLBank to make principal or interest payments due on any consolidated obligation, regardless of whether there has been a default by a FHLBank having primary liability. To the extent that a FHLBank makes any consolidated obligation payment on behalf of another FHLBank, the paying FHLBank is entitled to reimbursement from the FHLBank with primary liability. However, if the Finance Agency determines that the primary obligor is unable to satisfy its obligations, then the Finance Agency may allocate the outstanding liability among the remaining FHLBanks on a pro rata basis in proportion to each FHLBank’s participation in all consolidated obligations outstanding, or on any other basis that the Finance Agency may determine. No FHLBank has ever failed to make any payment on a consolidated obligation for which it was the primary obligor; as a result, the regulatory provisions for directing other FHLBanks to make payments on behalf of another FHLBank or allocating the liability among other FHLBanks have never been invoked. The joint and several obligations are mandated by Finance Agency regulations and are not the result of arms-length transactions among the FHLBanks. As described above, the FHLBanks have no control over the amount of the guaranty or the determination of how each FHLBank would perform under the joint and several liability. If the Bank expected that it would be required to pay any amounts on behalf of its co-obligors under its joint and several liability, the Bank would charge to income the amount of the expected payment. Based upon the creditworthiness of the other FHLBanks, the Bank currently believes that the likelihood that it would have to pay any amounts beyond those for which it is primarily liable is remote. Impact of Hurricanes Harvey and Irma. During the three months ended September 30, 2017, two significant hurricanes struck the continental United States. On August 25, 2017, Hurricane Harvey made landfall near Rockport, Texas, causing substantial flooding and other damage in southeast Texas, including the Houston metropolitan area, and lesser damage in Louisiana. Then, on September 10, 2017, Hurricane Irma made landfall near Marco Island, Florida, causing significant damage in Florida and lesser damage in other southeastern states. These storms had varying degrees of impact on the Bank’s members, its members’ borrowers and the properties pledged as collateral for those borrowings, and MPF mortgage loan borrowers and the properties pledged as collateral for those mortgage loans. Based on the information that is currently available, the Bank does not currently expect that the potential losses, if any, resulting from these hurricanes will have a material effect on its financial condition or results of operations. However, as more information becomes available over time, its assessment of the impact of these hurricanes may change. Member institutions throughout the district could be adversely affected over time and to varying degrees by Hurricanes Harvey and Irma, including, potentially, the inability of their borrowers to repay loans made by the institutions and damage to the borrowers’ properties that serve as collateral for the loans made by the institutions. The primary source of repayment of advances (including those that may be created when letters of credit have been funded) is derived from the borrowing members’ ongoing operations. For a variety of reasons, it is still too early to assess the impact that insurance settlements and federal and/or other assistance for members’ consumer and commercial borrowers will have on the borrowers’ ability to repair or rebuild their homes and businesses and repay outstanding loans to member institutions, or what assistance might be available to those institutions from their primary regulators or through Congressional action. If a member institution fails or is otherwise unable to meet its obligations, a secondary source of repayment is the collateral pledged by the member. When Hurricanes Harvey and Irma struck, approximately 333 of the Bank’s member institutions had outstanding obligations that were secured in part by collateral that was located in areas that were subsequently designated as disaster areas by the Federal Emergency Management Agency (“FEMA”) as a result of these storms. Of these institutions, the Bank identified 20 members with a high concentration of loans secured by properties located in the FEMA-designated disaster areas relative to their total pledged collateral. For a variety of reasons, including forbearances provided to borrowers for loan payments, the uncertainty of the amount of damage sustained by the underlying properties, the amount of insurance settlements that may be made on those properties, and the ultimate marketability of those properties, it is not possible at this time to determine the impact that the hurricanes may have had on the value of the loan collateral supporting the Bank’s advances and letters of credit. If the value of pledged loan collateral declines such that a member’s obligations to the Bank are not fully secured, that member would have to either substitute collateral or reduce its outstanding obligations to the Bank. As more information becomes available to the Bank over time, its assessment of the impact of the hurricanes on individual institutions’ operations may change. At this time, all principal and interest amounts on the Bank’s advances have been received in accordance with the contractual terms of the applicable agreements. Additionally, the Bank has not been required to fund any letters of credit. At the time the storms struck, the Bank also held interests totaling approximately $58 million (unpaid principal balance or “UPB”) in conventional mortgage loans acquired through the MPF Program and held for portfolio that were collateralized by properties located in the areas that were ultimately designated as disaster areas by FEMA, making them eligible for individual assistance from the federal government (approximately $14 million UPB was collateralized by properties located in Hurricane Harvey disaster areas and approximately $44 million UPB was collateralized by properties located in Hurricane Irma disaster areas). As a percentage of balances as of December 31, 2017, the aggregate UPB represents approximately 6.6 percent of the Bank’s mortgage loans held for portfolio, less than 0.1 percent of the Bank’s total assets and approximately 6.1 percent of the Bank’s retained earnings. Under the terms of the MPF Program, all mortgagors are required to carry hazard insurance and, if the property is located in a federal government-designated flood zone, they must also carry flood insurance. Federal assistance may also be available to mortgagors affected by the storms. In addition, mortgage loans with a loan-to-value ratio greater than 80 percent are required to have private mortgage insurance (“PMI”). Members selling mortgage loans to the Bank under the MPF Program are also required to retain a portion of the credit risk associated with those loans (“MPF credit enhancements”). The Bank is still assessing the damage to the underlying properties and the potential for recovery under insurance policies and MPF credit enhancements. While it is not currently possible to quantify the ultimate impact of the hurricanes on its mortgage loan portfolio, the Bank believes the protections that are in place including, but not limited to, borrowers’ equity, PMI, hazard insurance and, if applicable, flood insurance, along with MPF credit enhancements, will limit any potential losses to an amount that will not have a material effect on the Bank’s financial condition or results of operations. The Bank also owns several non-agency RMBS that are collateralized in part by loans on properties that are located in Florida and, to a lesser extent, Texas (the states most affected by Hurricanes Irma and Harvey, respectively). Credit support for the senior tranches of these securities held by the Bank is provided by subordinated tranches that absorb losses before the senior tranches held by the Bank would be affected. The amount of loans in Florida and Texas generally represent a small portion of the underlying loan pools and, therefore, the Bank does not currently anticipate any material losses in its non-agency RMBS portfolio related to Hurricanes Irma or Harvey. Based on currently available information, the Bank did not record any reserves related to Hurricanes Harvey or Irma as of December 31, 2017. The Bank is continuing to evaluate the impact of the hurricanes on its advances (including those that may be created if a letter of credit is required to be funded), mortgage loans held for portfolio and non-agency RMBS investments. If information becomes available indicating that any of these assets has been impaired and the amount of the loss can be reasonably estimated, the Bank will record appropriate reserves at that time. Impact of California Wildfires. In October and December, 2017, several significant wildfires destroyed thousands of homes and businesses in Northern and Southern California, respectively. The Bank’s primary exposure to the destruction caused by these wildfires relates to its mortgage loans held for portfolio. As of December 31, 2017, the Bank held interests totaling approximately $83 million UPB in conventional mortgage loans acquired through the MPF Program that were collateralized by properties located in the areas that have been designated as disaster areas by FEMA, making them eligible for individual assistance from the federal government. As of December 31, 2017, this balance represented approximately 9.4 percent of the Bank’s mortgage loans held for portfolio, approximately 0.1 percent of the Bank’s total assets and approximately 8.8 percent of the Bank’s retained earnings. As noted in the discussion regarding Hurricanes Harvey and Irma, all mortgagors are required under the terms of the MPF Program to carry hazard insurance. For this reason and the other reasons set forth in that discussion, the Bank does not currently anticipate any material losses as a result of the California wildfires. Other commitments and contingencies. At December 31, 2017 and 2016 , the Bank had commitments to make additional advances totaling approximately $20,200,000 and $35,400,000 , respectively. At December 31, 2017 , $17,200,000 of the outstanding commitments to make additional advances expire in 2018 and the remainder expire in 2019. The Bank issues standby letters of credit for a fee on behalf of its members. Standby letters of credit serve as performance guarantees. If the Bank is required to make payment for a beneficiary’s draw on the letter of credit, the amount funded is converted into a collateralized advance to the member. Letters of credit are fully collateralized in the same manner as advances (see Note 6). Outstanding standby letters of credit totaled $16,215,472,000 and $11,186,897,000 at December 31, 2017 and 2016 , respectively. At December 31, 2017 , outstanding letters of credit had original terms of up to 8 years with a final expiration in 2023 . Unearned fees on standby letters of credit are recorded in other liabilities and totaled $3,980,000 and $3,726,000 at December 31, 2017 and 2016 , respectively. Based on management’s credit analyses and collateral requirements, the Bank does not deem it necessary to have any provision for credit losses on these letters of credit (see Note 8). During 2017, the Bank entered into standby bond purchase agreements with one state housing associate within its district whereby, for a fee, the Bank agrees to serve as a standby liquidity provider. If required, the Bank will purchase and hold the housing associate's bonds until the designated marketing agent can find a suitable investor or the housing associate repurchases the bonds according to a schedule established by the agreement. Each standby bond purchase agreement includes the provisions under which the Bank would be required to purchase the bonds. At December 31, 2017, the Bank had outstanding standby bond purchase agreements totaling $207,663,000 , each of which expires in 2022. The Bank was not required to purchase any bonds under these agreements during the year ended December 31, 2017. The Bank was not a party to any standby bond purchase agreements during the years ended December 31, 2016 or 2015. At December 31, 2017 and 2016 , the Bank had commitments to purchase conventional mortgage loans totaling $20,304,000 and $2,030,000 , respectively, from certain of its PFIs. At December 31, 2017 and 2016 , the Bank had commitments to issue $55,000,000 and $45,000,000 , respectively, of consolidated obligation bonds, all of which were hedged with interest rate swaps. In addition, at December 31, 2016 , the Bank had commitments to issue $500,000 of consolidated obligation discount notes, none of which were hedged. The Bank did not have any commitments to issue consolidated obligation discount notes at December 31, 2017 . The Bank has transacted interest rate exchange agreements with large financial institutions and third-party clearinghouses that are subject to collateral exchange arrangements. As of December 31, 2017 and 2016 , the Bank had pledged cash collateral of $137,201,000 and $312,705,000 , respectively, to those parties that had credit risk exposure to the Bank related to interest rate exchange agreements. The pledged cash collateral (i.e., interest-bearing deposit asset) is netted against derivative assets and liabilities in the statements of condition. In addition, as of December 31, 2017 and 2016 , the Bank had pledged securities with carrying values (and fair values) of $747,230,000 and $613,351,000 , respectively, to parties that had credit risk exposure to the Bank related to interest rate exchange agreements. The pledged securities may be rehypothecated and are not netted against derivative assets and liabilities in the statement of condition. During the years ended December 31, 2017, 2016 and 2015 , the Bank charged to operating expenses net rental costs of approximately $370,000 , $394,000 , and $405,000 , respectively. Future minimum rentals at December 31, 2017 , were as follows (in thousands): Year Premises Equipment Total 2018 $ 381 $ 30 $ 411 2019 284 — 284 2020 149 — 149 Total $ 814 $ 30 $ 844 Lease agreements for Bank premises generally provide for increases in the base rentals resulting from increases in property taxes and maintenance expenses. These increases are not expected to have a material effect on the Bank. The Bank has entered into certain lease agreements to rent space to outside parties in its building. Future minimum rentals under these operating leases at December 31, 2017 were as follows (in thousands): Year Total 2018 $ 1,419 2019 1,443 2020 1,369 2021 919 2022 223 Total $ 5,373 In the ordinary course of its business, the Bank is subject to the risk that litigation may arise. Currently, the Bank is not a party to any material pending legal proceedings. For a discussion of other commitments and contingencies, see Notes 11, 12 and 15. |

Transactions with Shareholders [Abstract] | |
Transactions with Stockholders [Text Block] | Transactions with Shareholders As a cooperative, the Bank’s capital stock is owned by its members, by former members that retain the stock as provided in the Bank’s Capital Plan or by non-member institutions that have acquired members and must retain the stock to support advances or other activities with the Bank. No shareholder owns more than 10% of the voting interests of the Bank due to statutory limits on members’ voting rights. As of December 31, 2017 , nine of the Bank’s directors were member directors. By law, member directors must be officers or directors of a member of the Bank. Substantially all of the Bank’s advances are made to its shareholders (while eligible to borrow from the Bank, housing associates are not required or allowed to hold capital stock). In addition, the majority of its mortgage loans held for portfolio were purchased from certain of its shareholders. The Bank maintains demand deposit accounts for shareholders primarily as an investment alternative for their excess cash and to facilitate settlement activities that are directly related to advances. As an additional service to members, the Bank also offers term deposit accounts. Further, the Bank offers interest rate swaps, caps and floors to its members. Periodically, the Bank may sell (or purchase) federal funds to (or from) shareholders and/or their affiliates. These transactions are executed on terms that are the same as those with other eligible third-party market participants, except that the Bank’s underwriting guidelines specify a lower minimum threshold for the amount of capital that members must have to be an eligible federal funds counterparty than non-members. The Bank has never held any direct equity investments in its shareholders or their affiliates. Affiliates of two of the Bank’s derivative counterparties (Citigroup and Wells Fargo) acquired member institutions on March 31, 2005 and October 1, 2006, respectively. Since the acquisitions were completed, the Bank has continued to enter into interest rate exchange agreements with Citigroup and Wells Fargo in the normal course of business and under the same terms and conditions as before. Effective October 1, 2006, Citigroup terminated the Ninth District charter of the affiliate that acquired the member institution and, as a result, an affiliate of Citigroup became a non-member shareholder of the Bank. The Bank did not purchase any debt or equity securities issued by any of its shareholders or their affiliates during the years ended December 31, 2017 , 2016 or 2015 . All transactions with shareholders are entered into in the ordinary course of business. The Bank provides the same pricing for advances and other services to all similarly situated members regardless of asset or transaction size, charter type, or geographic location. The Bank provides, in the ordinary course of its business, products and services to members whose officers or directors may serve as directors of the Bank (“Directors’ Financial Institutions”). Finance Agency regulations require that transactions with Directors’ Financial Institutions be made on the same terms as those with any other member. As of December 31, 2017 and 2016 , advances outstanding to Directors’ Financial Institutions aggregated $1,376,896,000 and $1,708,177,000 , respectively, representing 3.8 percent and 5.3 percent, respectively, of the Bank’s total outstanding advances as of those dates. The Bank did not acquire any mortgage loans from Directors’ Financial Institutions during the years ended December 31, 2017 , 2016 or 2015 . As of December 31, 2017 and 2016 , capital stock outstanding to Directors’ Financial Institutions aggregated $83,008,000 and $87,189,000 , respectively, representing 3.6 percent and 4.5 percent of the Bank’s outstanding capital stock at each of those dates. For purposes of this determination, the Bank’s outstanding capital stock includes those shares that are classified as mandatorily redeemable. |

Accounting Policies [Abstract] | |
Use of Estimates, Policy [Policy Text Block] | Use of Estimates and Assumptions. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make assumptions and estimates. These assumptions and estimates may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expenses. Significant estimates include the valuations of the Bank’s investment securities, as well as its derivative instruments and any associated hedged items. Actual results could differ from these estimates. |
Interest Bearing Deposits, Securities Purchased Under Agreements To Resell And Federal Funds Sold [Policy Text Block] | Federal Funds Sold, Securities Purchased Under Agreements to Resell, Loans to Other FHLBanks and Interest-Bearing Deposits. These investments are carried at cost. |
Investment, Policy [Policy Text Block] | Investment Securities. The Bank records investment securities on trade date. The Bank carries investment securities for which it has both the ability and intent to hold to maturity (held-to-maturity securities) at cost, adjusted for the amortization of premiums and accretion of discounts using the level-yield method. The carrying amount of held-to-maturity securities is further adjusted for any other-than-temporary impairment charges, as described below. The Bank classifies certain investment securities that it may sell before maturity as available-for-sale and carries them at fair value. For available-for-sale securities that have been hedged (with fixed-for-floating interest rate swaps) and qualify as fair value hedges, the Bank records the portion of the change in value related to the risk being hedged in other income (loss) as “net gains (losses) on derivatives and hedging activities” together with the related change in the fair value of the derivative, and records the remainder of the change in value of the securities in other comprehensive income as “net unrealized gains (losses) on available-for-sale securities.” The Bank classifies certain other investments as trading and carries them at fair value. The Bank records changes in the fair value of these investments in other income (loss) in the statements of income. Although the securities are classified as trading, the Bank does not engage in active or speculative trading practices. The Bank computes the amortization and accretion of premiums and discounts on mortgage-backed securities ("MBS") for which prepayments are probable and reasonably estimable using the level-yield method over the estimated lives of the securities. This method requires a retrospective adjustment of the effective yield each time the Bank changes the estimated life as if the new estimate had been known since the original acquisition date of the securities. The Bank computes the amortization and accretion of premiums and discounts on other investments using the level-yield method to the contractual maturity of the securities. The Bank computes gains and losses on sales of investment securities using the specific identification method and includes these gains and losses in other income (loss) in the statements of income. The Bank treats securities purchased under agreements to resell as collateralized financings. The Bank evaluates outstanding available-for-sale and held-to-maturity securities for other-than-temporary impairment on a quarterly basis. An investment security is impaired if the fair value of the investment is less than its amortized cost. Amortized cost includes adjustments (if any) made to the cost basis of an investment for accretion, amortization, the credit portion of previous other-than-temporary impairments and hedging. The Bank considers the impairment of a debt security to be other than temporary if the Bank (i) intends to sell the security, (ii) more likely than not will be required to sell the security before recovering its amortized cost basis, or (iii) does not expect to recover the security’s entire amortized cost basis (even if the Bank does not intend to sell the security). Further, an impairment is considered to be other than temporary if the Bank’s best estimate of the present value of cash flows expected to be collected from the debt security is less than the amortized cost basis of the security (any such shortfall is referred to as a “credit loss”). If an other-than-temporary impairment (“OTTI”) occurs because the Bank intends to sell an impaired debt security, or more likely than not will be required to sell the security before recovery of its amortized cost basis, the impairment is recognized currently in earnings in an amount equal to the entire difference between fair value and amortized cost. In instances in which a determination is made that a credit loss exists but the Bank does not intend to sell the debt security and it is not more likely than not that the Bank will be required to sell the debt security before the anticipated recovery of its remaining amortized cost basis, the other-than-temporary impairment (i.e., the difference between the security’s then-current carrying amount and its estimated fair value) is separated into (i) the amount of the total impairment related to the credit loss (i.e., the credit component) and (ii) the amount of the total impairment related to all other factors (i.e., the non-credit component). The credit component is recognized in earnings and the non-credit component is recognized in other comprehensive income. The total other-than-temporary impairment is presented in the statement of income with an offset for the amount of the total other-than-temporary impairment that is recognized in other comprehensive income. The non-credit component of any OTTI losses recognized in other comprehensive income for debt securities classified as held-to-maturity is accreted over the remaining life of the debt security (in a prospective manner based on the amount and timing of future estimated cash flows) as an increase in the carrying value of the security unless and until the security is sold, the security matures, or there is an additional other-than-temporary impairment that is recognized in earnings. In instances in which an additional other-than-temporary impairment is recognized in earnings, the amount of the credit loss is reclassified from accumulated other comprehensive income (loss) ("AOCI") to earnings. Further, if an additional other-than-temporary impairment is recognized in earnings and the held-to-maturity security’s then-current carrying amount exceeds its fair value, an additional non-credit impairment is concurrently recognized in other comprehensive income. Conversely, if an additional other-than-temporary impairment is recognized in earnings and the held-to-maturity security’s then-current carrying value is less than its fair value, the carrying value of the security is not increased. In periods subsequent to the recognition of an OTTI loss, the other-than-temporarily impaired debt security is accounted for as if it had been purchased on the measurement date of the other-than-temporary impairment at an amount equal to the previous amortized cost basis less the other-than-temporary impairment recognized in earnings. The difference between the new amortized cost basis and the cash flows expected to be collected is accreted as interest income over the remaining life of the security in a prospective manner based on the amount and timing of future estimated cash flows. In instances when there is a significant increase in a security's expected cash flows, the amount to be accreted is adjusted prospectively. |
Federal Home Loan Bank Advances Policy [Policy Text Block] | Advances. The Bank reports advances at their principal amount outstanding, net of unearned commitment fees and deferred prepayment fees, if any, as discussed below. The Bank credits interest on advances to income as earned. |
Finance, Loan and Lease Receivables, Held-for-investment, Policy [Policy Text Block] | Mortgage Loans Held for Portfolio. Through the Mortgage Partnership Finance ® (“MPF” ® ) program administered by the FHLBank of Chicago, the Bank invests in conventional residential mortgage loans. Under the MPF program, the Bank purchased conventional mortgage loans and government-guaranteed/insured mortgage loans (i.e., those insured or guaranteed by the Federal Housing Administration (“FHA”) or the Department of Veterans Affairs (“DVA”)) during the period from 1998 to mid-2003. The Bank resumed acquiring conventional mortgage loans under this program in 2016. In 2017 and 2016, all of the acquired mortgage loans were originated by certain of the Bank's member institutions that participate in the MPF program ("Participating Financial Institutions" or “PFIs”) and the Bank acquired a 100 percent interest in such loans. For loans that were acquired from its members during the period from 1998 to mid-2003, the Bank retained title to the mortgage loans, subject to any participation interest in such loans that was sold to the FHLBank of Chicago; the interest in these loans that was retained by the Bank ranged from 1 percent to 49 percent. Additionally, during the period from 1998 to 2000, the Bank also acquired from the FHLBank of Chicago a percentage interest (ranging up to 75 percent) in certain MPF loans originated by PFIs of other FHLBanks. The Bank manages the liquidity, interest rate and prepayment risk of these loans, while the PFIs or their designees retain the servicing activities. The Bank and the PFIs share in the credit risk of the loans with the Bank assuming the first loss obligation limited by the First Loss Account (“FLA”), and the PFIs assuming credit losses in excess of the FLA, up to the amount of the credit enhancement obligation as specified in the master agreement (“Second Loss Credit Enhancement”). The Bank assumes all losses in excess of the Second Loss Credit Enhancement. |
Loans and Leases Receivable, Origination Fees, Discounts or Premiums, and Direct Costs to Acquire Loans Policy [Policy Text Block] | The Bank classifies mortgage loans held for portfolio as held for investment and, accordingly, reports them at their principal amount outstanding net of deferred premiums, discounts and the fair value amount of the delivery commitment (which represents the unrealized gains and losses from loans initially classified as mortgage loan commitments) as of the purchase (i.e., settlement) date. The Bank credits interest on mortgage loans to income as earned. The Bank amortizes or accretes the deferred amounts to interest income using the contractual method. The contractual method uses the cash flows required by the loan contracts, as adjusted for any actual prepayments, to apply the interest method. Future prepayments of principal are not anticipated under this method. The Bank has the ability and intent to hold these mortgage loans until maturity. |
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block] | Allowance for Credit Losses. An allowance for credit losses is separately established for each of the Bank’s identified portfolio segments, if necessary, to provide for probable losses inherent in its financing receivables portfolio and other off-balance sheet credit exposures as of the balance sheet date. To the extent necessary, an allowance for credit losses for off-balance sheet credit exposures is recorded as a liability. See Note 8 — Allowance for Credit Losses for information regarding the determination of the allowance for credit losses. A portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. The Bank has developed and documented a systematic methodology for determining an allowance for credit losses for the following portfolio segments: (1) advances and other extensions of credit to members, collectively referred to as “extensions of credit to members;” (2) government-guaranteed/insured mortgage loans held for portfolio; and (3) conventional mortgage loans held for portfolio. Classes of financing receivables are generally a disaggregation of a portfolio segment and are determined on the basis of their initial measurement attribute, the risk characteristics of the financing receivable and an entity’s method for monitoring and assessing credit risk. Because the credit risk arising from the Bank’s financing receivables is assessed and measured at the portfolio segment level, the Bank does not have separate classes of financing receivables within each of its portfolio segments. |
Loans and Leases Receivable, Nonaccrual Loan and Lease Status, Policy [Policy Text Block] | The Bank places a conventional mortgage loan on nonaccrual status when the collection of the contractual principal or interest is 90 days or more past due. When a mortgage loan is placed on nonaccrual status, accrued but uncollected interest is reversed against interest income. The Bank records cash payments received on nonaccrual loans first as interest income until it recovers all interest, and then as a reduction of principal. A loan on nonaccrual status is restored to accrual status when none of its contractual principal and interest is due and unpaid, and the Bank expects repayment of the remaining contractual interest and principal. Government-guaranteed/insured loans are not placed on nonaccrual status. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Collateral-dependent loans that are on nonaccrual status are measured for impairment based on the fair value of the underlying mortgaged property less estimated selling costs. Loans are considered collateral-dependent if repayment is expected to be provided solely by the sale of the underlying property; that is, there is no other available and reliable source of repayment. A collateral-dependent loan is impaired if the fair value of the underlying collateral is insufficient to recover the unpaid principal balance on the loan. Interest income on impaired loans is recognized in the same manner as it is for nonaccrual loans noted above. The Bank evaluates whether to record a charge-off on a conventional mortgage loan when the loan becomes 180 days or more past due or upon the occurrence of a confirming event, whichever occurs first. Confirming events include, but are not limited to, the occurrence of foreclosure or notification of a claim against any of the credit enhancements. A charge-off is recorded if the recorded investment in the loan will not be recovered. |
Finance, Loan and Lease Receivables, Held for Investments, Foreclosed Assets Policy [Policy Text Block] | Real Estate Owned. Real estate owned includes assets that have been received in satisfaction of debt or as a result of actual or in-substance foreclosures. Real estate owned is initially recorded at fair value less estimated costs to sell (and subsequently carried at the lower of cost or fair value less estimated costs to sell) and is included in other assets in the statements of condition. If the fair value of the real estate owned less estimated costs to sell is less than the recorded investment in the mortgage loan at the date of transfer, the Bank recognizes a charge-off to the allowance for loan losses. Subsequent realized gains and realized or unrealized losses are included in other income (loss) in the statements of income. |
Property, Plant and Equipment, Policy [Policy Text Block] | Premises and Equipment. The Bank records premises and equipment at cost less accumulated depreciation and amortization. At December 31, 2017 and 2016 , the Bank’s accumulated depreciation and amortization relating to premises and equipment was $33,698,000 and $31,573,000 , respectively. The Bank computes depreciation using the straight-line method over the estimated useful lives of assets ranging from 3 to 39 years. It amortizes leasehold improvements on the straight-line basis over the shorter of the estimated useful life of the improvement or the remaining term of the lease. The Bank capitalizes improvements and major renewals but expenses ordinary maintenance and repairs when incurred. Depreciation and amortization expense was $2,212,000 , $2,124,000 and $2,176,000 during the years ended December 31, 2017, 2016 and 2015 , respectively. The Bank includes gains and losses on disposal of premises and equipment, if any, in other income (loss) under the caption “other, net.” |
Internal Use Software, Policy [Policy Text Block] | Computer Software. The cost of purchased computer software and certain costs incurred in developing computer software for internal use are capitalized and amortized over future periods. As of December 31, 2017 and 2016 , the Bank had $3,264,000 and $2,635,000 , respectively, in unamortized computer software costs included in other assets. Amortization of computer software costs charged to expense was $1,518,000 , $1,944,000 and $1,744,000 for the years ended December 31, 2017, 2016 and 2015 , respectively. |
Derivatives, Policy [Policy Text Block] | Derivatives and Hedging Activities. The Bank accounts for derivatives and hedging activities in accordance with the guidance in Topic 815 of the Financial Accounting Standards Board’s ("FASB") Accounting Standards Codification entitled “Derivatives and Hedging” (“ASC 815”). All derivatives are recognized on the statements of condition at their fair values, including accrued interest receivable and payable. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments (including the right to reclaim cash collateral and the obligation to return cash collateral) where a legally enforceable right of setoff exists. Changes in the fair value of a derivative that is effective as — and that is designated and qualifies as — a fair value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk (including changes that reflect gains or losses on firm commitments), are recorded in current period earnings. Any hedge ineffectiveness (which represents the amount by which the change in the fair value of the derivative differs from the change in the fair value of the hedged item attributable to the hedged risk) is recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” Net interest income/expense associated with derivatives that qualify for fair value hedge accounting under ASC 815 is recorded as a component of net interest income. If fair value hedging relationships meet certain criteria specified in ASC 815, they are eligible for hedge accounting and the offsetting changes in fair value of the hedged items may be recorded in earnings. The application of hedge accounting generally requires the Bank to evaluate the effectiveness of the fair value hedging relationships on an ongoing basis and to calculate the changes in fair value of the derivatives and related hedged items independently. This is commonly known as the “long-haul” method of accounting. Transactions that meet more stringent criteria qualify for the “shortcut” method of hedge accounting in which an assumption can be made that the change in fair value of a hedged item exactly offsets the change in value of the related derivative. The Bank considers hedges of committed advances to be eligible for the shortcut method of accounting as long as the settlement of the committed advance occurs within the shortest period possible for that type of instrument based on market settlement conventions, the fair value of the swap is zero at the inception of the hedging relationship, and the transaction meets all of the other criteria for shortcut accounting specified in ASC 815. The Bank has defined the market settlement convention to be five business days or less for advances. Changes in the fair value of a derivative that is designated and qualifies as a cash flow hedge, to the extent that the hedge is effective, are recorded in AOCI until earnings are affected by the variability of the cash flows of the hedged transaction. Any ineffective portion of a cash flow hedge (which represents the amount by which the change in the fair value of the derivative differs from the change in fair value of a hypothetical derivative having terms that match identically the critical terms of the hedged forecasted transaction) is recognized in other income (loss) as “net gains (losses) on derivatives and hedging activities.” An economic hedge is defined as a derivative hedging specific or non-specific assets or liabilities that does not qualify or was not designated for hedge accounting under ASC 815, but is an acceptable hedging strategy under the Bank’s Enterprise Market Risk Management Policy. These hedging strategies also comply with Finance Agency regulatory requirements prohibiting speculative derivative transactions. An economic hedge by definition introduces the potential for earnings variability as changes in the fair value of a derivative designated as an economic hedge are recorded in current period earnings with no offsetting fair value adjustment to an asset or liability. Both the net interest income/expense and the fair value changes associated with derivatives in economic hedging relationships are recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” The Bank records the changes in fair value of all derivatives (and, in the case of fair value hedges, the hedged items) beginning on the trade date. Cash flows associated with all derivatives are reported as cash flows from operating activities in the statements of cash flows, unless the derivative contains an other-than-insignificant financing element, in which case its cash flows are reported as cash flows from financing activities. The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is “embedded” and the financial instrument that embodies the embedded derivative instrument is not remeasured at fair value with changes in fair value reported in earnings as they occur. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as either (1) a hedging instrument in a fair value hedge or (2) a stand-alone derivative instrument pursuant to an economic hedge. However, if the entire contract were to be measured at fair value, with changes in fair value reported in current earnings, or if the Bank could not reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract would be carried on the statement of condition at fair value and no portion of the contract would be separately accounted for as a derivative. The Bank discontinues hedge accounting prospectively when: (1) management determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item; (2) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (3) it is no longer probable that a forecasted transaction will occur within the originally specified time frame; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management determines that designating the derivative as a hedging instrument in accordance with ASC 815 is no longer appropriate. In all cases in which hedge accounting is discontinued and the derivative remains outstanding, the Bank will carry the derivative at its fair value on the statement of condition, recognizing any additional changes in the fair value of the derivative in current period earnings. When fair value hedge accounting for a specific derivative is discontinued due to the Bank’s determination that such derivative no longer qualifies for hedge accounting treatment or because the derivative is terminated, the Bank will cease to adjust the hedged asset or liability for changes in fair value and amortize the cumulative basis adjustment on the formerly hedged item into earnings over its remaining term using the level-yield method. When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the Bank continues to carry the derivative on the statement of condition at its fair value, removing from the statement of condition any asset or liability that was recorded to recognize the firm commitment and recording it as a gain or loss in current period earnings. When cash flow hedge accounting for a specific derivative is discontinued due to the Bank's determination that such derivative no longer qualifies for hedge accounting treatment or because the derivative is terminated, the Bank will reclassify the cumulative fair value gains or losses recorded in AOCI as of the discontinuance date from AOCI into earnings when earnings are affected by the original forecasted transaction, except in cases where the cash flow hedge is discontinued because the forecasted transaction is no longer probable (i.e., the forecasted transaction will not occur in the originally expected period or within an additional two-month period of time thereafter). In such cases, any fair value gains or losses recorded in AOCI as of the determination date are immediately reclassified to earnings as a component of "gains (losses) on derivatives and hedging activities." Similarly, if the Bank expects at any time that continued reporting of a net loss in AOCI would lead to recognizing a net loss on the combination of the hedging instrument and hedged transaction in one or more future periods, the amount that is not expected to be recovered is immediately reclassified to earnings as a component of "gains (losses) on derivatives and hedging activities." |
Derivatives, Offsetting Fair Value Amounts, Policy [Policy Text Block] | For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments (including the right to reclaim cash collateral and the obligation to return cash collateral) where a legally enforceable right of setoff exists. |
Derivatives, Embedded Derivatives [Policy Text Block] | The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is “embedded” and the financial instrument that embodies the embedded derivative instrument is not remeasured at fair value with changes in fair value reported in earnings as they occur. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as either (1) a hedging instrument in a fair value hedge or (2) a stand-alone derivative instrument pursuant to an economic hedge. However, if the entire contract were to be measured at fair value, with changes in fair value reported in current earnings, or if the Bank could not reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract would be carried on the statement of condition at fair value and no portion of the contract would be separately accounted for as a derivative. |
Derivatives, Hedge Discontinuances [Policy Text Block] | The Bank discontinues hedge accounting prospectively when: (1) management determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item; (2) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (3) it is no longer probable that a forecasted transaction will occur within the originally specified time frame; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management determines that designating the derivative as a hedging instrument in accordance with ASC 815 is no longer appropriate. In all cases in which hedge accounting is discontinued and the derivative remains outstanding, the Bank will carry the derivative at its fair value on the statement of condition, recognizing any additional changes in the fair value of the derivative in current period earnings. When fair value hedge accounting for a specific derivative is discontinued due to the Bank’s determination that such derivative no longer qualifies for hedge accounting treatment or because the derivative is terminated, the Bank will cease to adjust the hedged asset or liability for changes in fair value and amortize the cumulative basis adjustment on the formerly hedged item into earnings over its remaining term using the level-yield method. When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the Bank continues to carry the derivative on the statement of condition at its fair value, removing from the statement of condition any asset or liability that was recorded to recognize the firm commitment and recording it as a gain or loss in current period earnings. When cash flow hedge accounting for a specific derivative is discontinued due to the Bank's determination that such derivative no longer qualifies for hedge accounting treatment or because the derivative is terminated, the Bank will reclassify the cumulative fair value gains or losses recorded in AOCI as of the discontinuance date from AOCI into earnings when earnings are affected by the original forecasted transaction, except in cases where the cash flow hedge is discontinued because the forecasted transaction is no longer probable (i.e., the forecasted transaction will not occur in the originally expected period or within an additional two-month period of time thereafter). In such cases, any fair value gains or losses recorded in AOCI as of the determination date are immediately reclassified to earnings as a component of "gains (losses) on derivatives and hedging activities." Similarly, if the Bank expects at any time that continued reporting of a net loss in AOCI would lead to recognizing a net loss on the combination of the hedging instrument and hedged transaction in one or more future periods, the amount that is not expected to be recovered is immediately reclassified to earnings as a component of "gains (losses) on derivatives and hedging activities." |
Shares Subject to Mandatory Redemption, Changes in Redemption Value, Policy [Policy Text Block] | Mandatorily Redeemable Capital Stock. The Bank reclassifies shares of capital stock from the capital section to the liability section of its statement of condition at the point in time when a member submits a written redemption notice, gives notice of its intent to withdraw from membership, or becomes a non-member by merger or acquisition, charter termination, or involuntary termination from membership, as the shares of capital stock then meet the definition of a mandatorily redeemable financial instrument. Shares of capital stock meeting this definition are reclassified to liabilities at fair value. Following reclassification of the stock, any dividends paid or accrued on such shares are recorded as interest expense in the statement of income. Repurchase or redemption of these mandatorily redeemable financial instruments is reported as a cash outflow in the financing activities section of the statement of cash flows. If a member cancels a written redemption or withdrawal notice, the Bank reclassifies the shares subject to the cancellation notice from liabilities back to equity. Following this reclassification to equity, dividends on the capital stock are once again recorded as a reduction of retained earnings. Although mandatorily redeemable capital stock is excluded from capital for financial reporting purposes, it is considered capital for regulatory purposes. See Note 14 for more information, including restrictions on stock redemption. |
Federal Home Loan Bank Assessments, Policy [Policy Text Block] | Affordable Housing Program. The FHLB Act requires each FHLBank to establish and fund an Affordable Housing Program (“AHP”) (see Note 11). The Bank charges the required funding for AHP to earnings and establishes a liability. The Bank makes AHP funds available to members in the form of direct grants to assist in the purchase, construction, or rehabilitation of housing for very low-, low-, and moderate-income households. |
Prepayment fees on Federal Home Loan Bank Advances, Policy [Policy Text Block] | Prepayment Fees. The Bank charges a prepayment fee when members/borrowers prepay certain advances before their original maturities. The Bank records prepayment fees received from members/borrowers net of hedging adjustments included in the book basis of the prepaid advance, if any, as interest income on advances in the statements of income either immediately (as prepayment fees on advances) or over time (as interest income on advances), as further described below. In cases in which the Bank funds a new advance concurrent with or within a short period of time before or after the prepayment of an existing advance, the Bank evaluates whether the new advance meets the accounting criteria to qualify as a modification of an existing advance. If the new advance qualifies as a modification of the existing advance, the net prepayment fee on the prepaid advance is deferred, recorded in the basis of the modified advance, and amortized into interest income over the life of the modified advance using the level-yield method. This amortization is recorded in interest income on advances. If the Bank determines that the advance should be treated as a new advance, or in instances where no new advance is funded, it records the net fees as “prepayment fees on advances” in the interest income section of the statements of income. |
Loans and Leases Receivable, Commitment Fee Policy | Commitment Fees. The Bank defers commitment fees for advances and amortizes them to interest income using the level-yield method over the life of the advance. The Bank records commitment fees for letters of credit as a deferred credit when it receives the fees and amortizes them over the term of the letter of credit using the straight-line method. |
Debt, Policy [Policy Text Block] | Concessions on Consolidated Obligations. The Bank defers and amortizes, using the level-yield method, the amounts paid to securities dealers in connection with the sale of consolidated obligation bonds over the term to maturity of the related bonds. The Office of Finance prorates the amount of the concession to the Bank based upon the percentage of the debt issued that is assumed by the Bank. Unamortized concessions were $2,238,000 and $1,308,000 at December 31, 2017 and 2016 , respectively, and are recorded as a reduction in the balance of consolidated obligation bonds on the statements of condition. Amortization of such concessions is included in consolidated obligation bond interest expense and totaled $846,000 , $1,261,000 and $2,544,000 during the years ended December 31, 2017, 2016 and 2015 , respectively. The Bank charges to expense as incurred the concessions applicable to the sale of consolidated obligation discount notes because of the short maturities of these notes. Concessions related to the sale of discount notes totaling $3,589,000 , $3,394,000 and $1,274,000 are included in interest expense on consolidated obligation discount notes in the statements of income for the years ended December 31, 2017, 2016 and 2015 , respectively. Discounts and Premiums on Consolidated Obligations. The Bank expenses the discounts on consolidated obligation discount notes using the level-yield method over the term to maturity of the related notes. It accretes the discounts and amortizes the premiums on consolidated obligation bonds to expense using the level-yield method over the term to maturity of the bonds. |
Regulator and Office of Finance, Costs Assessed on Federal Home Loan Bank, Policy [Policy Text Block] | Finance Agency and Office of Finance Expenses. The Bank is assessed its proportionate share of the costs of operating the Finance Agency and the Office of Finance. The assessment for the FHLBanks’ portion of the Finance Agency’s operating and capital expenditures is allocated among the FHLBanks based on the ratio between each FHLBank’s minimum required regulatory capital and the aggregate minimum required regulatory capital of all FHLBanks determined as of June 30 of each year. The expenses of the Office of Finance are shared on a pro rata basis with two-thirds based on each FHLBank’s total consolidated obligations outstanding (as of the current month-end) and one-third divided equally among all of the FHLBanks. These costs are included in the other expense section of the statements of income. |
Fair Value of Financial Instruments, Policy [Policy Text Block] | Estimated Fair Values. Some of the Bank’s financial instruments (e.g., advances) lack an available trading market characterized by transactions between a willing buyer and a willing seller engaging in an exchange transaction. Therefore, the Bank uses internal models employing assumptions regarding interest rates, volatilities, prepayments, and other factors to perform present-value calculations when disclosing estimated fair values for these financial instruments. The Bank assumes that book value approximates fair value for certain financial instruments with three months or less to repricing or maturity. For a discussion of the Bank's valuation techniques and the estimated fair values of its financial instruments, see Note 16. |
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash Flows. The Bank considers cash and due from banks as cash and cash equivalents in the statements of cash flows. |
