Summary of Significant Accounting Policies	'
	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, 2013. 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 14, 2014 (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.
	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 securities, the fair value of derivatives, the determination of OTTI on investments 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.
	Reclassifications: Certain amounts in the financial statements and related footnotes have been reclassified to conform to current period presentations. These reclassifications have no impact on total assets, net income, total comprehensive income, total capital or cash flows.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
Recently Issued Accounting Standards And Interpretations And Changes In And Adoptions Of Accounting Principles	'
	RECENTLY ISSUED ACCOUNTING STANDARDS AND INTERPRETATIONS AND CHANGES IN AND ADOPTIONS OF ACCOUNTING PRINCIPLES
	Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. In June 2014, the Financial Accounting Standards Board (FASB) issued guidance to change the accounting for repurchase-to-maturity transactions and linked repurchase financings to that of secured borrowings, which is consistent with the accounting for repurchase agreements. The amendments also require two new disclosures:(1) information about transfers accounted for as sales in transactions that are economically similar to repurchase agreements; (2) increased transparency about the types of collateral pledged for repurchase agreements and similar transactions accounted for as secured borrowings. The amendments are effective for the first interim or annual period beginning after December 15, 2014, which is January 1, 2015 for the FHLBank. The adoption of this amendment is not expected to a have a material impact on the FHLBank's financial condition, results of operations, or cash flows.
	Revenue Recognition. In May 2014, the FASB issued guidance to introduce a new revenue recognition model in which an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. This standard is effective for fiscal years beginning after December 15, 2016 (January 1, 2017 for the FHLBank), including interim periods within that reporting period. The FHLBank is currently evaluating the new guidance to determine the impact it will have, if any, on its financial condition, results of operations, or cash flows.
	Receivables - Troubled Debt Restructurings by Creditors. In January 2014, the FASB issued amendments intended to clarify when a creditor should be considered to have received physical possession of the residential real estate property collateralizing a consumer mortgage loan. These amendments clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, when either: (a) the creditor obtains legal title to the residential real estate property upon completion of a foreclosure; or (b) the borrower conveys all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The amendments are effective for interim and annual periods beginning after December 15, 2014 (January 1, 2015 for the FHLBank). Early adoption is permitted. The guidance may be adopted using a modified retrospective transition method or a prospective transition method. The adoption of this amendment is not expected to a have a material impact on the FHLBank's financial condition, results of operations, or cash flows.
	Joint and Several Liability. In February 2013, the FASB issued guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date. This guidance requires an entity to measure these obligations as the sum of: (1) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors; and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. In addition, this guidance requires an entity to disclose the nature and amount of the obligation as well as other information about these obligations. This guidance was effective for interim and annual periods beginning on or after December 15, 2013 (January 1, 2014 for the FHLBank) and was applied retrospectively to obligations with joint and several liabilities existing at the beginning of the current fiscal year. The adoption of this guidance did not have a material effect on the FHLBank’s financial condition, results of operations, or cash flows.

Other-than-temporary Impairment: For those securities for which an OTTI was determined to have occurred as of June 30, 2014 (that is, securities for which the FHLBank determined that it was more likely than not that the amortized cost basis would not be recovered), Table 3.8 presents a summary of the significant inputs used to measure the amount of credit loss recognized in earnings during this period as well as related current credit enhancement. Credit enhancement is defined as the percentage of subordinated tranches and over-collateralization, if any, in a security structure that will generally absorb losses before the FHLBank will experience a loss on the security. The calculated averages represent the dollar-weighted averages of all the private-label MBS/asset-backed securities (ABS) investments in each category shown. Private-label MBS/ABS are classified as prime, Alt-A and subprime based on the originator’s classification at the time of origination or based on classification by a Nationally Recognized Statistical Rating Organization (NRSRO) upon issuance of the MBS/ABS.

1	For the three months ended June 30, 2014 and 2013, securities previously impaired represent all securities that were impaired prior to April 1, 2014 and 2013, respectively. For the six months ended June 30, 2014 and 2013, securities previously impaired represent all securities that were impaired prior to January 1, 2014 and 2013, respectively.
2	The FHLBank amortizes the credit component based on estimated cash flows prospectively up to the amount of expected principal to be recovered. The discounted cash flows will move from the discounted loss value to the ultimate principal to be written off at the projected date of loss. If the expected cash flows improve, the amount of expected loss decreases which causes a corresponding decrease in the calculated amortization. Based on the level of improvement in the cash flows, the amortization could become a positive adjustment to income.
As of June 30, 2014, the fair value of a portion of the FHLBank’s held-to-maturity MBS portfolio was below the amortized cost of the securities due to interest rate volatility, illiquidity in the marketplace and credit deterioration in the U.S. mortgage markets that began in early 2008. However, the decline in fair value of these securities is considered temporary as the FHLBank expects to recover the entire amortized cost basis on the remaining held-to-maturity securities in unrecognized loss positions and neither intends to sell these securities nor is it more likely than not that the FHLBank will be required to sell these securities before its anticipated recovery of the remaining amortized cost basis. For state and local housing agency obligations, the FHLBank determined that all of the gross unrealized losses on these bonds were temporary because the strength of the underlying collateral and credit enhancements was sufficient to protect the FHLBank from losses based on current expectations.

	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 June 30, 2014 and December 31, 2013, the FHLBank had advances outstanding at interest rates ranging from 0.13 percent to 8.01 percent and 0.11 percent to 8.01 percent, respectively. Table 4.1 presents advances summarized by year of contractual maturity as of June 30, 2014 and December 31, 2013 (in thousands):

	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). The FHLBank’s advances as of June 30, 2014 and December 31, 2013 include callable advances totaling $4,535,070,000 and $5,056,133,000, respectively. Of these callable advances, there were $4,407,796,000 and $4,932,869,000 of variable rate advances as of June 30, 2014 and December 31, 2013, respectively.
	Convertible advances allow the FHLBank to convert an advance from one interest payment term structure to another. When issuing convertible advances, the FHLBank may purchase 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. As of June 30, 2014 and December 31, 2013, the FHLBank had convertible advances outstanding totaling $1,677,742,000 and $1,685,242,000, respectively.

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 its participating members. These mortgage loans are government-insured or guaranteed (by the Federal Housing Administration (FHA), the Department of Veterans Affairs (VA), the Rural Housing Service of the Department of Agriculture (RHS) and/or the Department of Housing and Urban Development (HUD)) loans and conventional residential loans credit-enhanced by participating financial institutions (PFI). 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.
	Roll-forward of Allowance for Credit Losses: As of June 30, 2014, the FHLBank determined that an allowance for credit losses was only necessary on conventional mortgage loans held for portfolio. Table 6.1 presents a roll-forward of the allowance for credit losses for the three and six months ended June 30, 2014 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 June 30, 2014 (in thousands):

	2	Exposure can change on a daily basis; and thus, there is often a short lag time between the date the exposure is identified, collateral is requested and collateral is actually received. Likewise, there is a lag time for excess collateral to be returned.
	The following tables provide information regarding gains and losses on derivatives and hedging activities by type of hedge and type of derivative and gains and losses by hedged item for fair value hedges.
	For the three and six months ended June 30, 2014 and 2013, the FHLBank recorded net gain (loss) on derivatives and hedging activities as presented in Table 7.2 (in thousands):

	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. For the three months ended June 30, 2014 and 2013, the FHLBank recorded net gain (loss) 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 as presented in Table 7.3 (in thousands):

	Based on credit analyses and collateral requirements, FHLBank management does not anticipate any credit losses on its derivative agreements. The maximum credit risk applicable to a single counterparty was $28,588,000 and $21,045,000 as of June 30, 2014 and December 31, 2013, respectively. The counterparty was the same each period.
	Certain of the FHLBank’s bilateral derivative instruments contain provisions that require the FHLBank to post additional collateral with its counterparties if there is deterioration in the FHLBank’s credit rating. If the FHLBank’s credit rating is lowered by an NRSRO, the FHLBank may be required to deliver additional collateral on bilateral derivative instruments in net liability positions. The aggregate fair value of all bilateral derivative instruments with derivative counterparties containing credit-risk-related contingent features that were in a net derivative liability position (before cash collateral and related accrued interest) as of June 30, 2014 and December 31, 2013 was $153,622,000 and $308,776,000, respectively, for which the FHLBank has posted collateral with a fair value of $68,876,000 and $200,815,000, respectively, in the normal course of business. If the FHLBank’s credit rating had been lowered one level (e.g., from double-A to single-A), the FHLBank would have been required to deliver an additional $63,200,000 and $77,830,000 of collateral to its bilateral derivative counterparties as of June 30, 2014 and December 31, 2013.
	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 June 30, 2014 or December 31, 2013.
	The FHLBank’s net exposure on derivative agreements is presented in Note 11.

	Consolidated obligation bonds are issued with either fixed rate coupon or variable rate coupon payment terms. Variable rate coupon bonds use a variety of indices for interest rate resets including LIBOR, U.S. Treasury bills, Prime and Constant Maturity Treasuries (CMT). In addition, to meet the specific needs of certain investors in consolidated obligation bonds, fixed rate and variable rate bonds may contain certain features that may result in complex coupon payment terms and call features. When the FHLBank issues structured bonds that present interest rate or other risks that are unacceptable to the FHLBank, it will simultaneously enter into derivatives containing offsetting features that effectively alter the terms of the complex bonds to the equivalent of simple fixed rate coupon bonds or variable rate coupon bonds tied to indices such as those detailed above.
	The FHLBank’s participation in consolidated obligation bonds outstanding as of June 30, 2014 and December 31, 2013 includes callable bonds totaling $8,771,000,000 and $8,302,000,000, respectively. The FHLBank uses the unswapped callable bonds for financing its callable advances (Note 4), MBS (Note 3) and mortgage loans (Note 5). Contemporaneous with a portion of its fixed rate callable bond issues, the FHLBank will also enter 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.

Affordable Housing Program	'
	AFFORDABLE HOUSING PROGRAM
	The Bank Act, as amended by the Financial Institutions Reform, Recovery and Enforcement Act of 1989, requires each FHLBank to establish an Affordable Housing Program (AHP). As a part of its AHP, the FHLBank provides subsidies in the form of direct grants or below-market interest rate advances to members that use the funds to assist in the purchase, construction or rehabilitation of housing for very low-, low- and moderate-income households. By regulation, to fund the AHP, the 12 district FHLBanks as a group must annually set aside the greater of $100,000,000 or 10 percent percent of the current year’s net earnings. For purposes of the AHP calculation, the term “net earnings” is defined as income before interest expense related to mandatorily redeemable capital stock and the assessment for AHP. The FHLBank accrues this expense monthly based on its net earnings.
	The amount set aside for AHP is charged to expense and recognized as a liability. As subsidies are provided through the disbursement of grants or issuance of subsidized advances, the AHP liability is reduced accordingly. If the FHLBank’s net earnings before AHP would ever be zero or less, the amount of AHP liability would generally be equal to zero. However, if the result of the aggregate 10 percent calculation described above is less than the $100,000,000 minimum for all 12 FHLBanks, then the Bank Act requires the shortfall to be allocated among the FHLBanks based on the ratio of each FHLBank’s income for the previous year. If an FHLBank determines that its required AHP contributions are exacerbating any financial instability of that FHLBank, it may apply to the Finance Agency for a temporary suspension of its AHP contributions. The FHLBank has never applied to the Finance Agency for a temporary suspension of its AHP contributions.

	CAPITAL
	The FHLBank is subject to three capital requirements under the provisions of the Gramm-Leach-Bliley Act (GLB Act) and the Finance Agency’s capital structure regulation. Regulatory capital does not include accumulated other comprehensive income (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 Finance Agency. 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 Finance Agency 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 Finance Agency 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 stock, any general loss allowance, if consistent with GAAP and not established for specific assets, and other amounts from sources determined by the Finance Agency 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 12.1 illustrates that the FHLBank was in compliance with its regulatory capital requirements as of June 30, 2014 and December 31, 2013 (in thousands):
	Table 12.1

	Leverage capital	$	1,666,044		$	2,143,723		$	1,697,515		$	2,519,168
	Mandatorily Redeemable Capital Stock: The FHLBank is a cooperative whose members and former members own all of the FHLBank’s capital stock. Member shares cannot be purchased or sold except between the FHLBank and its members at its $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 12.2 provides the related dollar amounts for activities recorded in “Mandatorily redeemable capital stock” during the three and six months ended June 30, 2014 and 2013 (in thousands):

	Table 12.3 shows the amount of mandatorily redeemable capital stock by contractual year of redemption as of June 30, 2014 and December 31, 2013 (in thousands). The year of redemption in Table 12.3 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 6 months (Class A Common Stock) or 5 years (Class B Common Stock) after the FHLBank receives notice for withdrawal. 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.

	TOTAL	$	4,519		$	4,764
	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. Finance Agency rules limit the ability of the FHLBank to create member excess stock under certain circumstances. 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 June 30, 2014, the FHLBank’s excess stock was less than one percent of total assets.
	Capital Classification Determination: The Finance Agency implemented the prompt corrective action (PCA) provisions of the Housing and Economic Recovery Act of 2008. The rule established four capital classifications (i.e., adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized) for FHLBanks and implemented the PCA provisions that apply to FHLBanks that are not deemed to be adequately capitalized. The Finance Agency 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 Finance Agency. Before implementing a reclassification, the Director of the Finance Agency 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 Finance Agency, the FHLBank has been classified as adequately capitalized.

Fair Value Disclosures [Abstract]	'
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. 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 June 30, 2014 and December 31, 2013.
	Subjectivity of Estimates: Estimates of the fair value of advances with options, mortgage instruments, derivatives with embedded options and consolidated obligation bonds with options using the methods described below and other methods 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 FHLBank records trading securities, derivative assets and derivative liabilities at fair value on a recurring basis and on occasion, certain private-label MBS/ABS and non-financial assets on a non-recurring basis. 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. These reclassifications, if any, are reported as transfers in/out as of the beginning of the quarter in which the changes occur. There were no transfers during the three and six months ended June 30, 2014 and 2013.
	The carrying value and fair value of the FHLBank’s financial assets and liabilities as of June 30, 2014 and December 31, 2013 are summarized in Tables 14.1 and 14.2 (in thousands). 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.

Fair Value Measurements: Tables 14.3 and 14.4 present, for each hierarchy level, the FHLBank’s assets and liabilities that are measured at fair value on a recurring or nonrecurring basis on the Statements of Condition as of June 30, 2014 and December 31, 2013 (in thousands). The FHLBank measures certain held-to-maturity securities at fair value on a nonrecurring basis due to the recognition of a credit loss. For held-to-maturity securities that had credit impairment recorded at period end for which no total impairment was recorded (the full amount of additional credit impairment was a reclassification from non-credit impairment previously recorded in AOCI), these securities were recorded at their carrying values and not fair value. Real estate owned is measured at fair value when the asset’s fair value less costs to sell is lower than its carrying amount.

Commitments And Contingencies	'
	Joint and Several Liability: As provided by the Bank Act or Finance Agency regulation and as described in Note 9, consolidated obligations are backed only by the financial resources of the FHLBanks. FHLBank Topeka is jointly and severally liable with the other 11 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 $769,174,697,000 and $735,906,150,000 as of June 30, 2014 and December 31, 2013, respectively. To the extent that an 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. Because the FHLBanks are subject to the authority of the Finance Agency as it relates to decisions involving the allocation of the joint and several liability for the FHLBank’s consolidated obligations, FHLBank Topeka regularly monitors the financial condition of the other 11 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 11 FHLBanks as of June 30, 2014, FHLBank Topeka has concluded that a loss accrual is not necessary at this time.
	Off-balance Sheet Commitments: As of June 30, 2014 and December 31, 2013, off-balance sheet commitments are presented in Table 15.1 (in thousands):

	Commitments to Extend Credit: Standby letters of credit are executed for members for a fee. A standby letter of credit is a short-term financing arrangement between the FHLBank and its member or non-member housing associate. If the FHLBank is required to make payment for a beneficiary’s draw, these amounts are converted into a collateralized advance to the member. As of June 30, 2014, outstanding standby letters of credit had original terms of 8 days to 10 years with a final expiration in 2020. As of December 31, 2013, outstanding standby letters of credit had original terms of 7 days to 10 years with a final expiration in 2020. Unearned fees as well as the value of the guarantees related to standby letters of credit are recorded in other liabilities and amounted to $837,000 and $996,000 as of June 30, 2014 and December 31, 2013, respectively. Standby letters of credit are fully collateralized with assets allowed by the FHLBank’s Member Products Policy (MPP). Standby credit facility (SCF) commitments legally bind and unconditionally obligate the FHLBank for additional advances to stockholders. These commitments are executed for members for a fee and are for terms of up to one year. Unearned fees are recorded in other liabilities and amounted to $14,000 and $45,000 as of June 30, 2014 and December 31, 2013, 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 letters of credit, SCF commitments 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 2016, though some are renewable at the option of the FHLBank.  As of June 30, 2014 and December 31, 2013, the total commitments for bond purchases were with two in-district and one out-of-district state housing authorities as well as one participation interest in a standby bond purchase agreement between another FHLBank and a state housing authority in its district. The FHLBank was not required to purchase any bonds under any agreements during the three and six months ended June 30, 2014 and 2013.
	Commitments to Fund or Purchase Mortgage Loans: These commitments that unconditionally obligate the FHLBank to fund/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 $456,000 and $(265,000) as of June 30, 2014 and December 31, 2013, respectively.

Transactions With Stockholders And Housing Associates	'
	The FHLBank is a cooperative whose members own 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 16.1 and 16.2 present information as of June 30, 2014 and December 31, 2013 on members that owned more than 10 percent of outstanding FHLBank regulatory capital stock in 2014 or 2013 (amounts in thousands). None of the officers or directors of these members currently serve on the FHLBank’s board of directors.

Summary Of Significant Accounting Policies (Policy)	6 Months Ended
	Jun. 30, 2014
Accounting Policies [Abstract]	'
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, 2013. 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 14, 2014 (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	'
	Reclassifications: Certain amounts in the financial statements and related footnotes have been reclassified to conform to current period presentations. These reclassifications have no impact on total assets, net income, total comprehensive income, total capital or cash flows.
Use Of Estimates	'
	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 securities, the fair value of derivatives, the determination of OTTI on investments 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.

Affordable Housing Program [Abstract]	'
Description of Affordable Housing Program Assessment Accounting	'
	The Bank Act, as amended by the Financial Institutions Reform, Recovery and Enforcement Act of 1989, requires each FHLBank to establish an Affordable Housing Program (AHP). As a part of its AHP, the FHLBank provides subsidies in the form of direct grants or below-market interest rate advances to members that use the funds to assist in the purchase, construction or rehabilitation of housing for very low-, low- and moderate-income households. By regulation, to fund the AHP, the 12 district FHLBanks as a group must annually set aside the greater of $100,000,000 or 10 percent percent of the current year’s net earnings. For purposes of the AHP calculation, the term “net earnings” is defined as income before interest expense related to mandatorily redeemable capital stock and the assessment for AHP. The FHLBank accrues this expense monthly based on its net earnings.
	The amount set aside for AHP is charged to expense and recognized as a liability. As subsidies are provided through the disbursement of grants or issuance of subsidized advances, the AHP liability is reduced accordingly. If the FHLBank’s net earnings before AHP would ever be zero or less, the amount of AHP liability would generally be equal to zero. However, if the result of the aggregate 10 percent calculation described above is less than the $100,000,000 minimum for all 12 FHLBanks, then the Bank Act requires the shortfall to be allocated among the FHLBanks based on the ratio of each FHLBank’s income for the previous year. If an FHLBank determines that its required AHP contributions are exacerbating any financial instability of that FHLBank, it may apply to the Finance Agency for a temporary suspension of its AHP contributions.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments, Policy [Policy Text Block]	'
	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. Although the FHLBank uses its best judgment in estimating the fair value of its financial instruments, there are inherent limitations in any valuation technique.
Fair Value Transfer, Policy [Policy Text Block]	'
	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. These reclassifications, if any, are reported as transfers in/out as of the beginning of the quarter in which the changes occur

Schedule Of Significant Inputs In Measuring Other Than Temporary Impairments Recognized In Earnings	'
	For those securities for which an OTTI was determined to have occurred as of June 30, 2014 (that is, securities for which the FHLBank determined that it was more likely than not that the amortized cost basis would not be recovered), Table 3.8 presents a summary of the significant inputs used to measure the amount of credit loss recognized in earnings during this period as well as related current credit enhancement. Credit enhancement is defined as the percentage of subordinated tranches and over-collateralization, if any, in a security structure that will generally absorb losses before the FHLBank will experience a loss on the security. The calculated averages represent the dollar-weighted averages of all the private-label MBS/asset-backed securities (ABS) investments in each category shown. Private-label MBS/ABS are classified as prime, Alt-A and subprime based on the originator’s classification at the time of origination or based on classification by a Nationally Recognized Statistical Rating Organization (NRSRO) upon issuance of the MBS/ABS.

	1	For the three months ended June 30, 2014 and 2013, securities previously impaired represent all securities that were impaired prior to April 1, 2014 and 2013, respectively. For the six months ended June 30, 2014 and 2013, securities previously impaired represent all securities that were impaired prior to January 1, 2014 and 2013, respectively.
	2	The FHLBank amortizes the credit component based on estimated cash flows prospectively up to the amount of expected principal to be recovered. The discounted cash flows will move from the discounted loss value to the ultimate principal to be written off at the projected date of loss. If the expected cash flows improve, the amount of expected loss decreases which causes a corresponding decrease in the calculated amortization. Based on the level of improvement in the cash flows, the amortization could become a positive adjustment to income.

Fair Value, Assets And Liabilities Measured On Recurring And Nonrecurring Basis	'
	Tables 14.3 and 14.4 present, for each hierarchy level, the FHLBank’s assets and liabilities that are measured at fair value on a recurring or nonrecurring basis on the Statements of Condition as of June 30, 2014 and December 31, 2013 (in thousands). The FHLBank measures certain held-to-maturity securities at fair value on a nonrecurring basis due to the recognition of a credit loss. For held-to-maturity securities that had credit impairment recorded at period end for which no total impairment was recorded (the full amount of additional credit impairment was a reclassification from non-credit impairment previously recorded in AOCI), these securities were recorded at their carrying values and not fair value. Real estate owned is measured at fair value when the asset’s fair value less costs to sell is lower than its carrying amount.

[1]	For the three months ended June 30, 2014 and 2013, securities previously impaired represent all securities that were impaired prior to April 1, 2014 and 2013, respectively. For the six months ended June 30, 2014 and 2013, securities previously impaired represent all securities that were impaired prior to January 1, 2014 and 2013, respectively.
[2]	The FHLBank amortizes the credit component based on estimated cash flows prospectively up to the amount of expected principal to be recovered. The discounted cash flows will move from the discounted loss value to the ultimate principal to be written off at the projected date of loss. If the expected cash flows improve, the amount of expected loss decreases which causes a corresponding decrease in the calculated amortization. Based on the level of improvement in the cash flows, the amortization could become a positive adjustment to income.

[1]	Amounts represent the application of the netting requirements that allow the FHLBank to settle positive and negative positions and also cash collateral, including initial or variation margin, and related accrued interest held or placed with the same clearing agent and/or derivative counterparty.
[2]	Exposure can change on a daily basis; and thus, there is often a short lag time between the date the exposure is identified, collateral is requested and collateral is actually received. Likewise, there is a lag time for excess collateral to be returned.

Consolidated obligations:	'	'
Obligation with Joint and Several Liability Arrangement, Description	'As provided by the Bank Act or Finance Agency regulation and as described in Note 9, consolidated obligations are backed only by the financial resources of the FHLBanks. FHLBank Topeka is jointly and severally liable with the other 11 FHLBanks for the payment of principal and interest on all of the consolidated obligations issued by the FHLBanks.	'
Obligation with Joint and Several Liability Arrangement, Recourse Provision, Description	'To the extent that an 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 FHLBankbs 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.	'
