Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION Basis of Presentation: The accompanying interim financial statements of the FHLBank are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and with the instruction provided by Article 10, Rule 10-01 of Regulation S-X. The financial statements contain all adjustments which are, in the opinion of management, necessary for a fair statement of the FHLBank’s financial position, results of operations and cash flows for the interim periods presented. All such adjustments were of a normal recurring nature. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full fiscal year or any other interim period. The FHLBank’s significant accounting policies and certain other disclosures are set forth in the notes to the audited financial statements for the year ended December 31, 2018 . The interim financial statements presented herein should be read in conjunction with the FHLBank’s audited financial statements and notes thereto, which are included in the FHLBank’s annual report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 18, 2019 (annual report on Form 10-K). The notes to the interim financial statements highlight significant changes to the notes included in the annual report on Form 10-K. Reclassifications : Certain immaterial amounts in the financial statements have been reclassified to conform to current period presentations. Use of Estimates : The preparation of financial statements under GAAP requires management to make estimates and assumptions as of the date of the financial statements in determining the reported amounts of assets, liabilities and estimated fair values and in determining the disclosure of any contingent assets or liabilities. Estimates and assumptions by management also affect the reported amounts of income and expense during the reporting period. The most significant of these estimates include the fair value of trading and available-for-sale securities, the fair value of derivatives and the allowance for credit losses. Many of the estimates and assumptions, including those used in financial models, are based on financial market conditions as of the date of the financial statements. Because of the volatility of the financial markets, as well as other factors that affect management estimates, actual results may vary from these estimates. Derivatives and Hedging Activities: Beginning January 1, 2019, the FHLBank adopted new hedge accounting guidance, which, among other things, impacts the presentation of gains (losses) on derivatives and hedging activities for qualifying hedges. Changes in the fair value of a derivative 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, are recorded in net interest income in the same line as the earnings effect of the hedged item. Net gains (losses) on derivatives and hedging activities for qualifying hedges recorded in net interest income include unrealized and realized gains (losses), which include net interest settlements. Prior to January 1, 2019, fair value hedge ineffectiveness (which represented the amount by which the change in the fair value of the derivative differed from the change in the fair value of the hedged item) was recorded in non-interest income as net gains (losses) on derivatives and hedging activities. Investment Securities: Securities that are not classified as trading or held-to-maturity are classified as available-for-sale and are carried at fair value. The change in fair value of available-for-sale securities is recorded in other comprehensive income (loss) (OCI) as net unrealized gains (losses) on available-for-sale securities. Beginning January 1, 2019, the FHLBank adopted new hedge accounting guidance, which, among other things, impacts the presentation of gains (losses) on derivatives and hedging activities for qualifying hedges, including fair value hedges of available-for-sale securities. For available-for-sale securities that have been hedged and qualify as a fair value hedge, the FHLBank records the portion of the change in the fair value of the investment related to the risk being hedged in available-for-sale interest income together with the related change in the fair value of the derivative, and records the remainder of the change in the fair value of the investment in OCI as net unrealized gains (losses) on available-for-sale securities. Prior to January 1, 2019, for available-for-sale securities that were hedged and qualified as a fair value hedge, the FHLBank recorded the portion of the change in the fair value of the investment related to the risk being hedged in non-interest income as net gains (losses) on derivatives and hedging activities together with the related change in the fair value of the derivative, and recorded the remainder of the change in the fair value of the investment in OCI as net unrealized gains (losses) on available-for-sale securities. Prepayment Fees on Advances : The FHLBank charges a borrower a prepayment fee when the borrower prepays certain advances before the original maturity. The FHLBank records prepayment fees net of basis adjustments related to hedging activities included in the carrying value of the advance as advance interest income in the Statements of Income. If a new advance does not qualify as a modification of an existing advance, the existing advance is treated as an advance termination and any prepayment fee, net of hedging adjustments, is recorded to advance interest income in the Statements of Income. If a new advance qualifies as a modification of an existing advance, any prepayment fee, net of hedging adjustments, is deferred, recorded in the basis of the modified advance, and amortized using a level-yield methodology over the life of the modified advance to advance interest income. If the modified advance is hedged and meets hedge accounting requirements, the modified advance is marked to benchmark or full fair value, depending on the risk being hedged, and subsequent fair value changes that are attributable to the hedged risk are recorded in advance interest income effective January 1, 2019. Prior to January 1, 2019, subsequent fair value changes were recorded in non-interest income as net gains (losses) on derivatives and hedging activities.

In October 2018, the Financial Accounting Standards Board (FASB) issued an amendment that permits use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the U.S. Treasury rate, the London Interbank Offered Rate (LIBOR) swap rate, the OIS rate based on the Fed Funds Effective Rate, and the Securities Industry and Financial Markets Association Municipal Swap Rate. The amendments apply to all entities that elect to apply hedge accounting of the benchmark interest rate. The amendments were adopted on a prospective basis for qualifying new or redesignated hedging relationships entered into on or after the date of adoption. The amendment was effective concurrently with ASU 2017-12 (see below) for annual periods, and interim periods within those annual periods, beginning January 1, 2019. The adoption of this guidance did not materially affect the FHLBank's application of hedge accounting or utilization of hedging strategies. Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15). In August 2018, the FASB issued an amendment to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments in this ASU require an entity in a hosting arrangement that is a service contract to follow existing guidance relating to internal-use software to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Costs to develop or obtain internal-use software that cannot be capitalized also cannot be capitalized for a hosting arrangement that is a service contract. Therefore, an entity in a hosting arrangement that is a service contract determines to which project stage (that is, preliminary project stage, application development stage, or post-implementation stage) an implementation activity relates. Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. The amendments in this ASU also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement. The amendments in this ASU will be effective for annual periods, and interim periods within those annual periods beginning after December 31, 2019, which is January 1, 2020 for the FHLBank. Early adoption of the amendments in this ASU is permitted, including adoption in any interim period, for all entities. The FHLBank does not plan on early adoption. The adoption of this guidance is not expected to have a material effect on the FHLBank's financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14). In August 2018, the FASB issued an amendment modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans to improve disclosure effectiveness. The amendments in the ASU remove disclosures that are no longer considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in this ASU are effective for annual periods ending after December 15, 2020, which is December 31, 2020 for the FHLBank. Early adoption is permitted. The FHLBank does not plan on early adoption. The adoption of this guidance will not have a material impact on the disclosures related to defined benefit plans and will not impact the FHLBank’s financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). In August 2018, the FASB issued an amendment that modifies the disclosure requirements for fair value measurements. This ASU removes the requirement to disclose: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; and (3) the valuation processes for Level 3 fair value measurements. The ASU requires disclosure of changes in unrealized gains and losses for the period included in OCI for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this ASU will be effective for annual periods, and interim periods within those annual periods beginning after December 31, 2019, which is January 1, 2020 for the FHLBank. Early adoption is permitted. The FHLBank does not plan on early adoption. The adoption of this guidance will not have a material impact on the disclosures related to fair value measurements and will not impact the FHLBank’s financial condition, results of operations or cash flows. Targeted Improvements to Accounting for Hedging Activities, as amended (ASU 2017-12) . In August 2017, the FASB issued an amendment to simplify the application of hedge accounting guidance in current GAAP and 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. In addition, the amendments include certain targeted improvements to the assessment of hedge effectiveness and permit, among other things, the following: • 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; • Measurement of the hedged item in a partial-term fair value hedge of interest rate risk by assuming the hedged item has a term that reflects only the designated cash flows being hedged; • Consideration only of how changes in the benchmark interest rate affect a decision to settle a prepayable 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, an entity can designate the variability in cash flows attributable to the contractually specified interest rate as the hedged risk; and • If an entity that applies the shortcut method determines that use of that method was not or is no longer appropriate, the entity may apply a long-haul method for assessing hedge effectiveness as long as the hedge is highly effective and the entity documents at inception which long-haul methodology it will use. The amendment became effective for annual periods, and interim periods within those annual periods beginning on January 1, 2019 for the FHLBank. The guidance did not affect the FHLBank's application of hedge accounting for existing hedge strategies. For all short-cut hedge accounting trades, the FHLBank updated existing documentation to designate a long-haul method to be utilized in the event a hedge ceases to qualify for the short-cut method. The guidance may also provide opportunities to enhance risk management through new hedge strategies, including partial term hedges. The adoption of this guidance did not have a material effect on the FHLBank's financial condition, results of operations or cash flows beyond a prospective change in income statement presentation for fair value hedge relationships and new required disclosures. Premium Amortization on Purchased Callable Debt Securities (ASU 2017-08). In March 2017, FASB issued an amendment to shorten the amortization period of any premium on callable debt securities to the first call date instead of over the contractual life of the instrument. The amendment does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is intended to reduce diversity in practice in the amortization of premiums and the consideration of how the potential of a security being called is factored into current impairment assessments. The amendment also intends to more closely align the amortization of premiums and discounts to the expectations incorporated into the market pricing of the instrument. The amendment became effective for annual periods, and interim periods within those annual periods beginning on January 1, 2019 for the FHLBank. The adoption of this guidance did not have an impact on the FHLBank's financial condition, results of operations or cash flows. Measurement of Credit Losses on Financial Instruments, as amended (ASU 2016-13). In June 2016, FASB issued amended guidance for the accounting of credit losses on financial instruments. The amendments require entities to measure expected credit losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. Additionally, under the new guidance, a financial asset, or a group of financial assets, measured at amortized cost basis is required to be presented at the net amount expected to be collected. The guidance also requires: • The statement of income to reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period; • The entities to determine the allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis in a similar manner to other financial assets measured at amortized cost basis. The initial allowance for credit losses is required to be added to the purchase price; • Credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses. The amendments limit the allowance for credit losses to the amount by which fair value is below amortized cost; and • Public entities to further disaggregate the current disclosure of credit quality indicators in relation to the amortized cost of financing receivables by the year of origination (i.e., vintage). The guidance is effective for the FHLBank for interim and annual periods beginning on January 1, 2020. Early application is permitted as of the interim and annual reporting periods beginning after December 15, 2018. The FHLBank does not plan on early adoption. The guidance should be applied using a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. In addition, entities are required to use a prospective transition approach for debt securities for which an other-than-temporary impairment (OTTI) charge had been recognized before the effective date; however, the FHLBank currently does not have any OTTI debt securities. The FHLBank's internal working group continues its implementation efforts of identifying key interpretive issues and potential impacts to processes and systems that determine the magnitude of the impact on the FHLBank's financial condition, results of operations and cash flows. The FHLBank does not expect this guidance to impact certain financial instruments, including Advances, Agency and government-sponsored enterprise investments, securities purchased under agreements to resell, and other overnight investments due to the specific terms, issuer guarantees, and/or collateralized nature of the instruments that result in high credit quality holdings with no expected credit losses. Adoption of this guidance is not expected to have a material impact on the FHLBank's municipal securities and short-term investments. The FHLBank is still evaluating the impact that adoption of this guidance will have on its mortgage loans held for portfolio. Leases (ASU 2016-02). In February 2016, FASB issued amendments to lease accounting guidance. Under the new guidance, lessees are required to recognize a lease liability and a right-of-use asset for all leases in the statement of financial condition, which effectively removes a source of off-balance sheet financing for operating leases. A distinction remains between finance leases and operating leases, but the assets and liabilities arising from operating leases are now also required to be recognized in the statement of financial condition. Lessor accounting is largely unchanged. The amendments became effective for annual periods, and interim periods within those annual periods, beginning on January 1, 2019 for the FHLBank. The adoption of this guidance did not have a material effect on the FHLBank's financial condition, results of operations or cash flows.

Advances [Abstract]
Advances	ADVANCES General Terms: The FHLBank offers a wide range of fixed and variable rate advance products with different maturities, interest rates, payment characteristics and optionality. As of March 31, 2019 and December 31, 2018 , the FHLBank had advances outstanding at interest rates ranging from 0.88 percent to 7.41 percent. Table 4.1 presents advances summarized by redemption term as of March 31, 2019 and December 31, 2018 (dollar amounts in thousands): Table 4.1 03/31/2019 12/31/2018 Redemption Term Amount Weighted Average Interest Rate Amount Weighted Average Interest Rate Due in one year or less $ 13,806,679 2.60 % $ 14,844,804 2.60 % Due after one year through two years 1,985,215 2.44 1,482,844 2.40 Due after two years through three years 1,261,938 2.63 1,442,333 2.53 Due after three years through four years 755,038 2.63 7,496,058 2.66 Due after four years through five years 9,287,897 2.67 816,702 2.68 Thereafter 2,773,434 2.59 2,695,008 2.58 Total par value 29,870,201 2.61 % 28,777,749 2.60 % Discounts (2,486 ) (3,413 ) Hedging adjustments (4,720 ) (44,223 ) TOTAL $ 29,862,995 $ 28,730,113 The FHLBank’s advances outstanding include advances that contain call options that may be exercised with or without prepayment fees at the borrower’s discretion on specific dates (call dates) before the stated advance maturities (callable advances). In exchange for receiving the right to call the advance on a predetermined call schedule, the borrower may pay a higher fixed rate for the advance relative to an equivalent maturity, non-callable, fixed rate advance. The borrower normally exercises its call options on these advances when interest rates decline (fixed rate advances) or spreads change (adjustable rate advances). Convertible advances allow the FHLBank to convert an advance from one interest payment term structure to another. When issuing convertible advances, the FHLBank purchases put options from a member that allow the FHLBank to convert the fixed rate advance to a variable rate advance at the current market rate or another structure after an agreed-upon lockout period. A convertible advance carries a lower interest rate than a comparable-maturity fixed rate advance without the conversion feature.

Mortgage Loans	MORTGAGE LOANS The MPF Program involves the FHLBank investing in mortgage loans, which have been funded by the FHLBank through or purchased from participating financial institutions (PFIs). These mortgage loans are government-guaranteed or -insured loans (by the Federal Housing Administration, the Department of Veterans Affairs, the Rural Housing Service of the Department of Agriculture and/or the Department of Housing and Urban Development) and conventional residential loans credit-enhanced by PFIs. Depending upon a member’s product selection, the servicing rights can be retained or sold by the participating member. The FHLBank does not buy or own any mortgage servicing rights.

Allowance For Credit Losses	ALLOWANCE FOR CREDIT LOSSES The FHLBank has established an allowance methodology for each of its portfolio segments: credit products (advances, letters of credit and other extensions of credit to borrowers); government mortgage loans held for portfolio; conventional mortgage loans held for portfolio; the direct financing lease receivable; term Federal funds sold; and term securities purchased under agreements to resell. Based on management's analyses of each portfolio segment, the FHLBank has only established an allowance for credit losses on its conventional mortgage loans held for portfolio. Allowance for Credit Losses : Table 6.1 presents a roll-forward of the allowance for credit losses for the three months ended March 31, 2019 and 2018 (in thousands): Table 6.1 Three Months Ended 03/31/2019 03/31/2018 Balance, beginning of the period $ 812 $ 1,208 Net (charge-offs) recoveries (66 ) (181 ) (Reversal) provision for credit losses 78 30 Balance, end of the period $ 824 $ 1,057 Table 6.2 presents the allowance for credit losses and the recorded investment as well as the method used to evaluate impairment relating to all portfolio segments regardless of whether or not an estimated credit loss has been recorded as of March 31, 2019 (in thousands). The recorded investment in a financing receivable is the UPB, adjusted for accrued interest, net deferred loan fees or costs, unamortized premiums or discounts, fair value hedging adjustments and direct write-downs. The recorded investment is not net of any valuation allowance.

Cash collateral posted was $83,311,000 and $58,902,000 as of March 31, 2019 and December 31, 2018 , respectively. Cash collateral received was $14,226,000 and $77,661,000 as of March 31, 2019 and December 31, 2018 , respectively. The FHLBank carries derivative instruments at fair value on its Statements of Condition. Any change in the fair value of derivatives designated under a fair value hedging relationship is recorded each period in current period earnings. Fair value hedge accounting allows for the offsetting fair value of the hedged risk in the hedged item to also be recorded in current period earnings. Beginning on January 1, 2019, changes in fair value of the derivative hedging instrument and the hedged item attributable to the hedged risk for designated fair value hedges are recorded in net interest income in the same line as the earnings effect of the hedged item. Prior to January 1, 2019, for fair value hedges, any hedge ineffectiveness (which represented the amount by which the change in the fair value of the derivative differed from the change in the fair value of the hedge item) was recorded in non-interest income as net gains (losses) on derivatives and hedging activities. Interest settlements on derivatives designated as fair value hedges were recorded in net interest income or expense prior to, and continue to be recorded in net interest income or expense after January 1, 2019. However, beginning on January 1, 2019, disclosed gains (losses) on fair value derivatives include unrealized changes in fair value as well as net interest settlements. For the three months ended March 31, 2019 and 2018 , the FHLBank recorded net gains (losses) on derivatives and the related hedged items in fair value hedging relationships and the impact of those derivatives on the FHLBank’s net interest income and net gains (losses) on derivatives and hedging activities, if applicable, as presented in Table 7.2 (in thousands): Table 7.2 03/31/2019 Interest Income/Expense Advances Available-for-sale Securities Consolidated Obligation Discount Notes Consolidated Obligation Bonds Total amounts presented in the Statements of Income $ 187,609 $ 15,396 $ 148,991 $ 158,157 Gains (losses) on fair value hedging relationships: Interest rate contracts: Derivatives 1 $ (33,072 ) $ (44,192 ) $ 32 $ 9,705 Hedged items 2 39,502 42,113 (30 ) (13,549 ) NET GAINS (LOSSES) ON FAIR VALUE HEDGING RELATIONSHIPS $ 6,430 $ (2,079 ) $ 2 $ (3,844 ) 03/31/2018 3 Interest Income/Expense Non-interest Income Advances Available-for-sale Securities Consolidated Obligation Bonds Net gains (losses) on derivatives and hedging activities Gains (losses) on fair value hedging relationships: Interest rate contracts: Derivatives 1 $ (2,465 ) $ (1,080 ) $ 923 $ 69,498 Hedged items 2 (1,156 ) (71,472 ) NET GAINS (LOSSES) ON FAIR VALUE HEDGING RELATIONSHIPS $ (3,621 ) $ (1,080 ) $ 923 $ (1,974 ) 1 Includes net interest settlements in interest income/expense. 2 Includes amortization/accretion on closed fair value relationships in interest income. 3 Prior period amounts were not conformed to new hedge accounting guidance adopted January 1, 2019.

The maximum credit risk applicable to a single counterparty was $13,785,000 and $25,799,000 as of March 31, 2019 and December 31, 2018 , respectively. The counterparty was the same for both periods . For uncleared derivative transactions, the FHLBank has entered into bilateral security agreements with its counterparties with bilateral-collateral-exchange provisions that require all credit exposures be collateralized, subject to minimum transfer amounts. The FHLBank utilizes two Derivative Clearing Organizations (Clearinghouse) for all cleared derivative transactions, LCH Limited and CME Clearing. At both Clearinghouses, initial margin is considered cash collateral. For cleared derivatives, the Clearinghouse determines initial margin requirements and generally, credit ratings are not factored into the initial margin. However, clearing agents may require additional initial margin to be posted based on credit considerations, including but not limited to credit rating downgrades. The FHLBank was not required to post additional initial margin by its clearing agents as of March 31, 2019 and December 31, 2018 . The FHLBank’s net exposure on derivative agreements is presented in Note 10 .

The FHLBank’s participation in consolidated obligation bonds outstanding as of March 31, 2019 and December 31, 2018 includes callable bonds totaling $8,424,000,000 and $8,559,000,000 , respectively. The FHLBank uses the unswapped callable bonds for financing its callable fixed rate advances (Note 4 ), MBS (Note 3 ) and mortgage loans (Note 5 ). Contemporaneous with a portion of its fixed rate callable bond issuances, the FHLBank also enters into interest rate swap agreements (in which the FHLBank generally pays a variable rate and receives a fixed rate) with call features that mirror the options in the callable bonds (a sold callable swap). The combined sold callable swap and callable debt transaction allows the FHLBank to obtain attractively priced variable rate financing.

Offsetting [Abstract]
Assets and Liabilities Subject to Offsetting	ASSETS AND LIABILITIES SUBJECT TO OFFSETTING The FHLBank presents certain financial instruments, including derivatives, repurchase agreements and securities purchased under agreements to resell, on a net basis by clearing agent by Clearinghouse, or by counterparty, when it has met the netting requirements. For these financial instruments, the FHLBank has elected to offset its asset and liability positions, as well as cash collateral received or pledged, and associated accrued interest. The FHLBank has analyzed the enforceability of offsetting rights incorporated in its cleared derivative transactions and determined that the exercise of those offsetting rights by a non-defaulting party under these transactions should be upheld under applicable law upon an event of default including a bankruptcy, insolvency, or similar proceeding involving the Clearinghouse or clearing agent, or both. Based on this analysis, the FHLBank presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse.

Stockholders' Equity Note [Abstract]
Capital	CAPITAL Capital Requirements: The FHLBank is subject to three capital requirements under the provisions of the Gramm-Leach-Bliley Act (GLB Act) and the Federal Housing Finance Agency's (FHFA) capital structure regulation. Regulatory capital does not include AOCI but does include mandatorily redeemable capital stock. • Risk-based capital. The FHLBank must maintain at all times permanent capital in an amount at least equal to the sum of its credit risk, market risk and operations risk capital requirements. The risk-based capital requirements are all calculated in accordance with the rules and regulations of the FHFA. Only permanent capital, defined as Class B Common Stock and retained earnings, can be used by the FHLBank to satisfy its risk-based capital requirement. The FHFA may require the FHLBank to maintain a greater amount of permanent capital than is required by the risk-based capital requirement as defined, but the FHFA has not placed any such requirement on the FHLBank to date. • Total regulatory capital. The GLB Act requires the FHLBank to maintain at all times at least a 4.0 percent total capital-to-asset ratio. Total regulatory capital is defined as the sum of permanent capital, Class A Common Stock, any general loss allowance, if consistent with GAAP and not established for specific assets, and other amounts from sources determined by the FHFA as available to absorb losses. • Leverage capital. The FHLBank is required to maintain at all times a leverage capital-to-assets ratio of at least 5.0 percent , with the leverage capital ratio defined as the sum of permanent capital weighted 1.5 times and non-permanent capital (currently only Class A Common Stock) weighted 1.0 times, divided by total assets. Table 11.1 illustrates that the FHLBank was in compliance with its regulatory capital requirements as of March 31, 2019 and December 31, 2018 (dollar amounts in thousands): Table 11.1 03/31/2019 12/31/2018 Required Actual Required Actual Regulatory capital requirements: Risk-based capital $ 451,611 $ 2,254,949 $ 387,729 $ 2,193,001 Total regulatory capital-to-asset ratio 4.0 % 4.3 % 4.0 % 5.1 % Total regulatory capital $ 2,297,108 $ 2,454,784 $ 1,908,610 $ 2,442,156 Leverage capital ratio 5.0 % 6.2 % 5.0 % 7.4 % Leverage capital $ 2,871,385 $ 3,582,259 $ 2,385,763 $ 3,538,656 Mandatorily Redeemable Capital Stock: The FHLBank is a cooperative whose members own most of the FHLBank’s capital stock. Former members (including certain non-members that own FHLBank capital stock as a result of merger or acquisition, relocation, charter termination, or involuntary termination of an FHLBank member) own the remaining capital stock to support business transactions still carried on the FHLBank's Statements of Condition. Shares cannot be purchased or sold except between the FHLBank and its members at a price equal to the $100 per share par value. If a member cancels its written notice of redemption or notice of withdrawal, the FHLBank will reclassify mandatorily redeemable capital stock from a liability to equity. After the reclassification, dividends on the capital stock would no longer be classified as interest expense. Table 11.2 presents a roll-forward of mandatorily redeemable capital stock for the three months ended March 31, 2019 and 2018 (in thousands): Table 11.2 Three Months Ended 03/31/2019 03/31/2018 Balance, beginning of period $ 3,597 $ 5,312 Capital stock subject to mandatory redemption reclassified from equity during the period 23,915 100,390 Redemption or repurchase of mandatorily redeemable capital stock during the period (24,006 ) (100,734 ) Stock dividend classified as mandatorily redeemable capital stock during the period 42 61 Balance, end of period $ 3,548 $ 5,029 Table 11.3 shows the amount of mandatorily redeemable capital stock by contractual year of redemption as of March 31, 2019 and December 31, 2018 (in thousands). The year of redemption in Table 11.3 is the end of the redemption period in accordance with the FHLBank’s capital plan. The FHLBank is not required to redeem or repurchase membership stock until six months (for Class A Common Stock) or five years (for Class B Common Stock) after the FHLBank receives notice for withdrawal from the member. Additionally, the FHLBank is not required to redeem or repurchase activity-based stock until any activity-based stock becomes excess stock as a result of an activity no longer remaining outstanding. However, the FHLBank intends to repurchase the excess activity-based stock of non-members to the extent that it can do so and still meet its regulatory capital requirements. Table 11.3 Contractual Year of Repurchase 03/31/2019 12/31/2018 Year 1 $ — $ — Year 2 — — Year 3 1 1 Year 4 1,785 1,798 Year 5 — — Past contractual redemption date due to remaining activity 1 1,762 1,798 TOTAL $ 3,548 $ 3,597 1 Represents mandatorily redeemable capital stock that is past the end of the contractual redemption period because there is activity outstanding to which the mandatorily redeemable capital stock relates. Excess Capital Stock: Excess capital stock is defined as the amount of stock held by a member (or former member) in excess of that institution’s minimum stock purchase requirement. FHFA rules limit the ability of the FHLBank to create excess member stock under certain circumstances. For example, the FHLBank may not pay dividends in the form of capital stock or issue new excess stock to members if the FHLBank’s excess stock exceeds one percent of its total assets or if the issuance of excess stock would cause the FHLBank’s excess stock to exceed one percent of its total assets. As of March 31, 2019 , the FHLBank’s excess stock was less than one percent of total assets. Capital Classification Determination: The FHFA determines each FHLBank’s capital classification on at least a quarterly basis. If an FHLBank is determined to be other than adequately capitalized, the FHLBank becomes subject to additional supervisory authority by the FHFA. Before implementing a reclassification, the Director of the FHFA is required to provide the FHLBank with written notice of the proposed action and an opportunity to submit a response. As of the most recent review by the FHFA for the fourth quarter of 2018 , the FHLBank was classified as adequately capitalized .

Fair Values

Fair Value Disclosures [Abstract]
Fair Values	FAIR VALUES The fair value amounts recorded on the Statements of Condition and presented in the note disclosures have been determined by the FHLBank using available market and other pertinent information and reflect the FHLBank’s best judgment of appropriate valuation methods. GAAP defines fair value 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 (i.e., an exit price). Although the FHLBank uses its best judgment in estimating the fair value of its financial instruments, there are inherent limitations in any valuation technique. Therefore, the fair values may not be indicative of the amounts that would have been realized in market transactions as of March 31, 2019 and December 31, 2018 . Additionally, these values do not represent an estimate of the overall market value of the FHLBank as a going concern, which would take into account future business opportunities and the net profitability of assets and liabilities. Subjectivity of Estimates: Estimates of the fair value of advances with options, mortgage instruments, derivatives with embedded options and consolidated obligation bonds with options are highly subjective and require judgments regarding significant matters such as the amount and timing of future cash flows, prepayment speed assumptions, expected interest rate volatility, methods to determine possible distributions of future interest rates used to value options, and the selection of discount rates that appropriately reflect market and credit risks. The use of different assumptions could have a material effect on the fair value estimates. Fair Value Hierarchy: The fair value hierarchy requires the FHLBank to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The inputs are evaluated and an overall level for the fair value measurement is determined. This overall level is an indication of the market observability of the fair value measurement for the asset or liability. The FHLBank must disclose the level within the fair value hierarchy in which the measurements are classified for all assets and liabilities. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels: • Level 1 Inputs – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the FHLBank can access on the measurement date. • Level 2 Inputs – Inputs other than quoted prices within Level 1 that are observable inputs 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 and liabilities in active markets; (2) quoted prices for similar assets and liabilities in markets that are not active; (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 by correlation or other means. • Level 3 Inputs – Unobservable inputs for the asset or liability. The FHLBank reviews its 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. There were no transfers of assets or liabilities between fair value levels during the three months ended March 31, 2019 and 2018 . Tables 13.1 and 13.2 present the carrying value, fair value and fair value hierarchy of financial assets and liabilities as of March 31, 2019 and December 31, 2018 . The FHLBank records trading securities, available-for-sale securities, derivative assets, and derivative liabilities at fair value on a recurring basis, and on occasion certain mortgage loans held for portfolio and certain other assets at fair value on a nonrecurring basis. The FHLBank measures all other financial assets and liabilities at amortized cost. Further details about the financial assets and liabilities held at fair value on either a recurring or non-recurring basis are presented in Tables 13.3 and 13.4 . The carrying value, fair value and fair value hierarchy of the FHLBank’s financial assets and liabilities as of March 31, 2019 and December 31, 2018 are summarized in Tables 13.1 and 13.2 (in thousands): Table 13.1 03/31/2019 Carrying Value Total Fair Value Level 1 Level 2 Level 3 Netting Adjustment and Cash Collateral 1 Assets: Cash and due from banks $ 12,917 $ 12,917 $ 12,917 $ — $ — $ — Interest-bearing deposits 238,363 238,363 — 238,363 — — Securities purchased under agreements to resell 4,273,438 4,273,438 — 4,273,438 — — Federal funds sold 1,950,000 1,950,000 — 1,950,000 — — Trading securities 3,907,002 3,907,002 — 3,907,002 — — Available-for-sale securities 3,911,021 3,911,021 — 3,911,021 — — Held-to-maturity securities 4,242,242 4,229,501 — 4,146,388 83,113 — Advances 29,862,995 29,883,120 — 29,883,120 — — Mortgage loans held for portfolio, net of allowance 8,701,250 8,812,569 — 8,811,376 1,193 — Accrued interest receivable 137,957 137,957 — 137,957 — — Derivative assets 85,015 85,015 — 56,835 — 28,180 Liabilities: Deposits 544,500 544,500 — 544,500 — — Consolidated obligation discount notes 26,785,113 26,785,088 — 26,785,088 — — Consolidated obligation bonds 27,400,165 27,330,525 — 27,330,525 — — Mandatorily redeemable capital stock 3,548 3,548 3,548 — — — Accrued interest payable 104,921 104,921 — 104,921 — — Derivative liabilities 408 408 — 41,313 — (40,905 ) Other Asset (Liability): Industrial revenue bonds 35,000 33,162 — 33,162 — — Financing obligation payable (35,000 ) (33,162 ) — (33,162 ) — — 1 Represents the effect of legally enforceable master netting agreements that allow the FHLBank to net settle positive and negative positions and also derivative cash collateral and related accrued interest held or placed with the same clearing agent or derivative counterparty .

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Joint and Several Liability: As provided in the Federal Home Loan Bank Act of 1932, as amended (Bank Act) or in FHFA regulations, consolidated obligations are backed only by the financial resources of the FHLBanks. FHLBank Topeka is jointly and severally liable with the other FHLBanks for the payment of principal and interest on all of the consolidated obligations issued by the FHLBanks. The par amounts for which FHLBank Topeka is jointly and severally liable were approximately $956,653,036,000 and $986,994,515,000 as of March 31, 2019 and December 31, 2018 , respectively. The joint and several obligations are mandated by FHFA 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. Because the FHLBanks are subject to the authority of the FHFA as it relates to decisions involving the allocation of the joint and several liability for all FHLBanks' consolidated obligations, FHLBank Topeka regularly monitors the financial condition of the other FHLBanks to determine whether it should expect a loss to arise from its joint and several obligations. If the FHLBank were to determine that a loss was probable and the amount of the loss could be reasonably estimated, the FHLBank would charge to income the amount of the expected loss. Based upon the creditworthiness of the other FHLBanks as of March 31, 2019 , FHLBank Topeka has concluded that a loss accrual is not necessary at this time. Off-balance Sheet Commitments: As of March 31, 2019 and December 31, 2018 , off-balance sheet commitments are presented in Table 14.1 (in thousands): Table 14.1 03/31/2019 12/31/2018 Notional Amount Expire Within One Year Expire After One Year Total Expire Within One Year Expire After One Year Total Standby letters of credit outstanding $ 3,871,177 $ 7,338 $ 3,878,515 $ 3,824,497 $ 37,933 $ 3,862,430 Advance commitments outstanding 110,230 42,188 152,418 116,475 43,782 160,257 Commitments for standby bond purchases 188,876 561,311 750,187 69,277 686,602 755,879 Commitments to fund or purchase mortgage loans 159,654 — 159,654 101,551 — 101,551 Commitments to issue consolidated bonds, at par 1,039,550 — 1,039,550 — — — Commitments to issue consolidated discount notes, at par — — — 1,825,000 — 1,825,000 Commitments to Extend Credit: The FHLBank issues standby letters of credit on behalf of its members to support certain obligations of the members to third-party beneficiaries. These standby letters of credit are subject to the same collateralization and borrowing limits that are applicable to advances and are fully collateralized with assets allowed by the FHLBank’s Member Products Policy (MPP). Standby letters of credit may be offered to assist members in facilitating residential housing finance, community lending, and asset-liability management, and to provide liquidity. In particular, members often use standby letters of credit as collateral for deposits from federal and state government agencies. Standby letters of credit are executed for members for a fee. If the FHLBank is required to make payment for a beneficiary's draw, the member either reimburses the FHLBank for the amount drawn or, subject to the FHLBank's discretion, the amount drawn may be converted into a collateralized advance to the member. However, standby letters of credit usually expire without being drawn upon. Standby letters of credit have original expiration periods of up to 10 years, currently expiring no later than 2023 . Unearned fees as well as the value of the guarantees related to standby letters of credit are recorded in other liabilities and amounted to $1,254,000 and $1,296,000 as of March 31, 2019 and December 31, 2018 , respectively. Advance commitments legally bind and unconditionally obligate the FHLBank for additional advances up to 24 months in the future. Based upon management’s credit analysis of members and collateral requirements under the MPP, the FHLBank does not expect to incur any credit losses on the outstanding letters of credit or advance commitments. Standby Bond-Purchase Agreements: The FHLBank has entered into standby bond purchase agreements with state housing authorities whereby the FHLBank, for a fee, agrees to purchase and hold the authorities’ bonds until the designated marketing agent can find a suitable investor or the housing authority repurchases the bond according to a schedule established by the standby agreement. Each standby agreement dictates the specific terms that would require the FHLBank to purchase the bond. The bond purchase commitments entered into by the FHLBank expire no later than 2022 , though some are renewable at the option of the FHLBank. As of March 31, 2019 and December 31, 2018 , the total commitments for bond purchases included agreements with two in-district state housing authorities. The FHLBank was not required to purchase any bonds under any agreements during the three months ended March 31, 2019 and 2018 . Commitments to Purchase Mortgage Loans: These commitments that unconditionally obligate the FHLBank to purchase mortgage loans from participating FHLBank Topeka members in the MPF Program are generally for periods not to exceed 60 calendar days. Certain commitments are recorded as derivatives at their fair values on the Statements of Condition. The FHLBank recorded mortgage delivery commitment net derivative asset (liability) balances of $693,000 and $549,000 as of March 31, 2019 and December 31, 2018 , respectively. Commitments to Issue Consolidated Obligations: The FHLBank enters into commitments to issue consolidated obligation bonds and discount notes outstanding in the normal course of its business. Most settle within the shortest period possible and are considered regular way trades; however, certain commitments are recorded as derivatives at their fair values on the Statements of Condition.

Federal Home Loan Banks [Abstract]
Transactions With Stockholders	TRANSACTIONS WITH STOCKHOLDERS The FHLBank is a cooperative whose members own most of the capital stock of the FHLBank and generally receive dividends on their investments. In addition, certain former members that still have outstanding transactions are also required to maintain their investments in FHLBank capital stock until the transactions mature or are paid off. Nearly all outstanding advances are with current members, and the majority of outstanding mortgage loans held for portfolio were purchased from current or former members. The FHLBank also maintains demand deposit accounts for members primarily to facilitate settlement activities that are directly related to advances and mortgage loan purchases. Transactions with members are entered into in the ordinary course of business. In instances where members also have officers or directors who are directors of the FHLBank, transactions with those members are subject to the same eligibility and credit criteria, as well as the same terms and conditions, as other transactions with members. For financial reporting and disclosure purposes, the FHLBank defines related parties as FHLBank directors’ financial institutions and members with capital stock investments in excess of 10 percent of the FHLBank’s total regulatory capital stock outstanding, which includes mandatorily redeemable capital stock. Activity with Members that Exceed a 10 Percent Ownership in FHLBank Capital Stock: Tables 15.1 and 15.2 present information on members that owned more than 10 percent of outstanding FHLBank regulatory capital stock as of March 31, 2019 and December 31, 2018 (dollar amounts in thousands).

Accounting Policies [Abstract]
Basis of Presentation, Policy	Basis of Presentation: The accompanying interim financial statements of the FHLBank are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and with the instruction provided by Article 10, Rule 10-01 of Regulation S-X. The financial statements contain all adjustments which are, in the opinion of management, necessary for a fair statement of the FHLBank’s financial position, results of operations and cash flows for the interim periods presented. All such adjustments were of a normal recurring nature. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full fiscal year or any other interim period. The FHLBank’s significant accounting policies and certain other disclosures are set forth in the notes to the audited financial statements for the year ended December 31, 2018 . The interim financial statements presented herein should be read in conjunction with the FHLBank’s audited financial statements and notes thereto, which are included in the FHLBank’s annual report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 18, 2019 (annual report on Form 10-K). The notes to the interim financial statements highlight significant changes to the notes included in the annual report on Form 10-K.
Reclassification, Policy	Reclassifications : Certain immaterial amounts in the financial statements have been reclassified to conform to current period presentations.
Use Of Estimates, Policy	Use of Estimates : The preparation of financial statements under GAAP requires management to make estimates and assumptions as of the date of the financial statements in determining the reported amounts of assets, liabilities and estimated fair values and in determining the disclosure of any contingent assets or liabilities. Estimates and assumptions by management also affect the reported amounts of income and expense during the reporting period. The most significant of these estimates include the fair value of trading and available-for-sale securities, the fair value of derivatives and the allowance for credit losses. Many of the estimates and assumptions, including those used in financial models, are based on financial market conditions as of the date of the financial statements. Because of the volatility of the financial markets, as well as other factors that affect management estimates, actual results may vary from these estimates.
Derivatives, Policy	Derivatives and Hedging Activities: Beginning January 1, 2019, the FHLBank adopted new hedge accounting guidance, which, among other things, impacts the presentation of gains (losses) on derivatives and hedging activities for qualifying hedges. Changes in the fair value of a derivative 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, are recorded in net interest income in the same line as the earnings effect of the hedged item. Net gains (losses) on derivatives and hedging activities for qualifying hedges recorded in net interest income include unrealized and realized gains (losses), which include net interest settlements. Prior to January 1, 2019, fair value hedge ineffectiveness (which represented the amount by which the change in the fair value of the derivative differed from the change in the fair value of the hedged item) was recorded in non-interest income as net gains (losses) on derivatives and hedging activities. Investment Securities: Securities that are not classified as trading or held-to-maturity are classified as available-for-sale and are carried at fair value. The change in fair value of available-for-sale securities is recorded in other comprehensive income (loss) (OCI) as net unrealized gains (losses) on available-for-sale securities. Beginning January 1, 2019, the FHLBank adopted new hedge accounting guidance, which, among other things, impacts the presentation of gains (losses) on derivatives and hedging activities for qualifying hedges, including fair value hedges of available-for-sale securities. For available-for-sale securities that have been hedged and qualify as a fair value hedge, the FHLBank records the portion of the change in the fair value of the investment related to the risk being hedged in available-for-sale interest income together with the related change in the fair value of the derivative, and records the remainder of the change in the fair value of the investment in OCI as net unrealized gains (losses) on available-for-sale securities. Prior to January 1, 2019, for available-for-sale securities that were hedged and qualified as a fair value hedge, the FHLBank recorded the portion of the change in the fair value of the investment related to the risk being hedged in non-interest income as net gains (losses) on derivatives and hedging activities together with the related change in the fair value of the derivative, and recorded the remainder of the change in the fair value of the investment in OCI as net unrealized gains (losses) on available-for-sale securities. Prepayment Fees on Advances : The FHLBank charges a borrower a prepayment fee when the borrower prepays certain advances before the original maturity. The FHLBank records prepayment fees net of basis adjustments related to hedging activities included in the carrying value of the advance as advance interest income in the Statements of Income. If a new advance does not qualify as a modification of an existing advance, the existing advance is treated as an advance termination and any prepayment fee, net of hedging adjustments, is recorded to advance interest income in the Statements of Income. If a new advance qualifies as a modification of an existing advance, any prepayment fee, net of hedging adjustments, is deferred, recorded in the basis of the modified advance, and amortized using a level-yield methodology over the life of the modified advance to advance interest income. If the modified advance is hedged and meets hedge accounting requirements, the modified advance is marked to benchmark or full fair value, depending on the risk being hedged, and subsequent fair value changes that are attributable to the hedged risk are recorded in advance interest income effective January 1, 2019. Prior to January 1, 2019, subsequent fair value changes were recorded in non-interest income as net gains (losses) on derivatives and hedging activities.
New Accounting Pronouncements, Policy	Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes (Accounting Standards Update (ASU) 2018-16) . In October 2018, the Financial Accounting Standards Board (FASB) issued an amendment that permits use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the U.S. Treasury rate, the London Interbank Offered Rate (LIBOR) swap rate, the OIS rate based on the Fed Funds Effective Rate, and the Securities Industry and Financial Markets Association Municipal Swap Rate. The amendments apply to all entities that elect to apply hedge accounting of the benchmark interest rate. The amendments were adopted on a prospective basis for qualifying new or redesignated hedging relationships entered into on or after the date of adoption. The amendment was effective concurrently with ASU 2017-12 (see below) for annual periods, and interim periods within those annual periods, beginning January 1, 2019. The adoption of this guidance did not materially affect the FHLBank's application of hedge accounting or utilization of hedging strategies. Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15). In August 2018, the FASB issued an amendment to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments in this ASU require an entity in a hosting arrangement that is a service contract to follow existing guidance relating to internal-use software to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Costs to develop or obtain internal-use software that cannot be capitalized also cannot be capitalized for a hosting arrangement that is a service contract. Therefore, an entity in a hosting arrangement that is a service contract determines to which project stage (that is, preliminary project stage, application development stage, or post-implementation stage) an implementation activity relates. Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. The amendments in this ASU also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement. The amendments in this ASU will be effective for annual periods, and interim periods within those annual periods beginning after December 31, 2019, which is January 1, 2020 for the FHLBank. Early adoption of the amendments in this ASU is permitted, including adoption in any interim period, for all entities. The FHLBank does not plan on early adoption. The adoption of this guidance is not expected to have a material effect on the FHLBank's financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14). In August 2018, the FASB issued an amendment modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans to improve disclosure effectiveness. The amendments in the ASU remove disclosures that are no longer considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in this ASU are effective for annual periods ending after December 15, 2020, which is December 31, 2020 for the FHLBank. Early adoption is permitted. The FHLBank does not plan on early adoption. The adoption of this guidance will not have a material impact on the disclosures related to defined benefit plans and will not impact the FHLBank’s financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). In August 2018, the FASB issued an amendment that modifies the disclosure requirements for fair value measurements. This ASU removes the requirement to disclose: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; and (3) the valuation processes for Level 3 fair value measurements. The ASU requires disclosure of changes in unrealized gains and losses for the period included in OCI for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this ASU will be effective for annual periods, and interim periods within those annual periods beginning after December 31, 2019, which is January 1, 2020 for the FHLBank. Early adoption is permitted. The FHLBank does not plan on early adoption. The adoption of this guidance will not have a material impact on the disclosures related to fair value measurements and will not impact the FHLBank’s financial condition, results of operations or cash flows. Targeted Improvements to Accounting for Hedging Activities, as amended (ASU 2017-12) . In August 2017, the FASB issued an amendment to simplify the application of hedge accounting guidance in current GAAP and 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. In addition, the amendments include certain targeted improvements to the assessment of hedge effectiveness and permit, among other things, the following: • 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; • Measurement of the hedged item in a partial-term fair value hedge of interest rate risk by assuming the hedged item has a term that reflects only the designated cash flows being hedged; • Consideration only of how changes in the benchmark interest rate affect a decision to settle a prepayable 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, an entity can designate the variability in cash flows attributable to the contractually specified interest rate as the hedged risk; and • If an entity that applies the shortcut method determines that use of that method was not or is no longer appropriate, the entity may apply a long-haul method for assessing hedge effectiveness as long as the hedge is highly effective and the entity documents at inception which long-haul methodology it will use. The amendment became effective for annual periods, and interim periods within those annual periods beginning on January 1, 2019 for the FHLBank. The guidance did not affect the FHLBank's application of hedge accounting for existing hedge strategies. For all short-cut hedge accounting trades, the FHLBank updated existing documentation to designate a long-haul method to be utilized in the event a hedge ceases to qualify for the short-cut method. The guidance may also provide opportunities to enhance risk management through new hedge strategies, including partial term hedges. The adoption of this guidance did not have a material effect on the FHLBank's financial condition, results of operations or cash flows beyond a prospective change in income statement presentation for fair value hedge relationships and new required disclosures. Premium Amortization on Purchased Callable Debt Securities (ASU 2017-08). In March 2017, FASB issued an amendment to shorten the amortization period of any premium on callable debt securities to the first call date instead of over the contractual life of the instrument. The amendment does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is intended to reduce diversity in practice in the amortization of premiums and the consideration of how the potential of a security being called is factored into current impairment assessments. The amendment also intends to more closely align the amortization of premiums and discounts to the expectations incorporated into the market pricing of the instrument. The amendment became effective for annual periods, and interim periods within those annual periods beginning on January 1, 2019 for the FHLBank. The adoption of this guidance did not have an impact on the FHLBank's financial condition, results of operations or cash flows. Measurement of Credit Losses on Financial Instruments, as amended (ASU 2016-13). In June 2016, FASB issued amended guidance for the accounting of credit losses on financial instruments. The amendments require entities to measure expected credit losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. Additionally, under the new guidance, a financial asset, or a group of financial assets, measured at amortized cost basis is required to be presented at the net amount expected to be collected. The guidance also requires: • The statement of income to reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period; • The entities to determine the allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis in a similar manner to other financial assets measured at amortized cost basis. The initial allowance for credit losses is required to be added to the purchase price; • Credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses. The amendments limit the allowance for credit losses to the amount by which fair value is below amortized cost; and • Public entities to further disaggregate the current disclosure of credit quality indicators in relation to the amortized cost of financing receivables by the year of origination (i.e., vintage). The guidance is effective for the FHLBank for interim and annual periods beginning on January 1, 2020. Early application is permitted as of the interim and annual reporting periods beginning after December 15, 2018. The FHLBank does not plan on early adoption. The guidance should be applied using a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. In addition, entities are required to use a prospective transition approach for debt securities for which an other-than-temporary impairment (OTTI) charge had been recognized before the effective date; however, the FHLBank currently does not have any OTTI debt securities. The FHLBank's internal working group continues its implementation efforts of identifying key interpretive issues and potential impacts to processes and systems that determine the magnitude of the impact on the FHLBank's financial condition, results of operations and cash flows. The FHLBank does not expect this guidance to impact certain financial instruments, including Advances, Agency and government-sponsored enterprise investments, securities purchased under agreements to resell, and other overnight investments due to the specific terms, issuer guarantees, and/or collateralized nature of the instruments that result in high credit quality holdings with no expected credit losses. Adoption of this guidance is not expected to have a material impact on the FHLBank's municipal securities and short-term investments. The FHLBank is still evaluating the impact that adoption of this guidance will have on its mortgage loans held for portfolio. Leases (ASU 2016-02). In February 2016, FASB issued amendments to lease accounting guidance. Under the new guidance, lessees are required to recognize a lease liability and a right-of-use asset for all leases in the statement of financial condition, which effectively removes a source of off-balance sheet financing for operating leases. A distinction remains between finance leases and operating leases, but the assets and liabilities arising from operating leases are now also required to be recognized in the statement of financial condition. Lessor accounting is largely unchanged. The amendments became effective for annual periods, and interim periods within those annual periods, beginning on January 1, 2019 for the FHLBank. The adoption of this guidance did not have a material effect on the FHLBank's financial condition, results of operations or cash flows.
Finance, Loan and Lease Receivables, Held-for-investment, Allowance and Nonperforming Loans, Allowance Policy [Policy Text Block]	The FHLBank has established an allowance methodology for each of its portfolio segments: credit products (advances, letters of credit and other extensions of credit to borrowers); government mortgage loans held for portfolio; conventional mortgage loans held for portfolio; the direct financing lease receivable; term Federal funds sold; and term securities purchased under agreements to resell. Based on management's analyses of each portfolio segment, the FHLBank has only established an allowance for credit losses on its conventional mortgage loans held for portfolio.
Derivatives, Offsetting Fair Value Amounts, Policy	The FHLBank presents certain financial instruments, including derivatives, repurchase agreements and securities purchased under agreements to resell, on a net basis by clearing agent by Clearinghouse, or by counterparty, when it has met the netting requirements. For these financial instruments, the FHLBank has elected to offset its asset and liability positions, as well as cash collateral received or pledged, and associated accrued interest. The FHLBank has analyzed the enforceability of offsetting rights incorporated in its cleared derivative transactions and determined that the exercise of those offsetting rights by a non-defaulting party under these transactions should be upheld under applicable law upon an event of default including a bankruptcy, insolvency, or similar proceeding involving the Clearinghouse or clearing agent, or both. Based on this analysis, the FHLBank presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse.
Fair Value Transfer, Policy	The FHLBank reviews its 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.
