Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	BASIS OF PRESENTATION Basis of Presentation: The accompanying interim financial statements of 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 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. 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, 2020. The interim financial statements presented herein should be read in conjunction with FHLBank’s audited financial statements and notes thereto, which are included in FHLBank’s annual report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 18, 2021 (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 and available-for-sale securities and the fair value of derivatives. 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.

Accounting Standards Update and Change in Accounting Principle [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 Reference Rate Reform (Accounting Standards Update (ASU) 2021-01). In January 2021, the Financial Accounting Standards Board (FASB) issued an amendment that refines the scope of Accounting Standards Codification (ASC) 848 and clarifies the guidance issued to facilitate the effects of reference rate reform on financial reporting. The amendment permits entities to elect certain optional expedients and exceptions when accounting for derivative contracts and certain hedging relationships affected by changes in the interest rates used for discounting cash flows, computing variation margin settlements and calculating price alignment interest in connection with reference rate reform activities. During the fourth quarter of 2020, FHLBank elected applicable optional expedients specific to discounting transition on a retrospective basis. As a result of electing this expedient, discounting transition did not have a material effect on FHLBank's financial condition, results of operations, or cash flows. This guidance was effective immediately for FHLBank and was applied consistently with the optional expedient guidance under ASU 2020-04, described below. Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04) . In March 2020, the FASB issued temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The transactions primarily include: (1) contract modifications; (2) hedging relationships; and (3) sale or transfer of debt securities classified as held-to-maturity. During the second quarter of 2021, FHLBank adopted a provision of ASU 2020-04 which allows a one-time election to sell, transfer, or both sell and transfer debt securities classified as held-to-maturity that reference a rate affected by reference rate reform and that were classified as held-to-maturity before January 1, 2020. See Note 15 - Subsequent Events for additional information related to this transfer. This guidance was effective immediately for FHLBank, and the amendments may be applied prospectively through December 31, 2022. FHLBank is in the process of evaluating the guidance and the other optional expedients, and the effect on FHLBank's financial condition, results of operations and cash flows has not yet been determined.

These investments are generally transacted with counterparties that have received a credit rating of triple-B or greater (investment grade) by a Nationally Recognized Statistical Ratings Organization (NRSRO). These may differ from internal ratings of the investments, if applicable. As of March 31, 2021, approximately 28 percent of these overnight investments were with counterparties not rated by an NRSRO. All transactions with unrated counterparties are secured transactions. Federal funds sold are unsecured loans that are generally transacted on an overnight term. Federal Housing Finance Agency (FHFA) regulations include a limit on the amount of unsecured credit FHLBank may extend to a counterparty. As of March 31, 2021 and December 31, 2020, all investments in interest-bearing deposits and Federal funds sold were repaid or expected to be repaid according to the contractual terms. No allowance for credit losses was recorded for these assets as of March 31, 2021 and December 31, 2020. Carrying values of interest-bearing deposits and Federal funds sold exclude accrued interest receivable of $60,000 and $5,000, respectively, as of March 31, 2021, and $80,000 and $3,000, respectively, as of December 31, 2020. Securities purchased under agreements to resell are short-term and are structured such that they are evaluated regularly to determine if the market value of the underlying securities decreases below the market value required as collateral (i.e., subject to collateral maintenance provisions). Based upon the collateral held as security and collateral maintenance provisions with its counterparties, FHLBank determined that no allowance for credit losses was needed for its securities purchased under agreements to resell as of March 31, 2021 and December 31, 2020. The carrying value of securities purchased under agreements excludes accrued interest receivable of $3,000 and $6,000 as of March 31, 2021 and December 31, 2020, respectively. Debt Securities: FHLBank invests in debt securities, which are classified as either trading, available-for-sale, or held-to-maturity. FHLBank is prohibited by FHFA regulations from purchasing certain higher-risk securities, such as equity securities and debt instruments that are not investment quality, other than certain investments targeted at low-income persons or communities and instruments that experienced credit deterioration after their purchase by FHLBank. FHLBank's debt securities include the following major security types, which are based on the issuer and the risk characteristics of the security: ▪ U.S. Treasury obligations - sovereign debt of the United States; ▪ GSE debentures - debentures issued by other FHLBanks, Federal National Mortgage Association (Fannie Mae), Federal Farm Credit Bank and Federal Agricultural Mortgage Corporation. GSE securities are not guaranteed by the U.S. government; ▪ State or local housing agency obligations - municipal bonds issued by housing finance agencies; ▪ U.S. obligation MBS - single-family MBS issued by Government National Mortgage Association (Ginnie Mae), which are guaranteed by the U.S. government; and ▪ GSE MBS - single-family and multifamily MBS issued by Fannie Mae and Federal Home Loan Mortgage Corporation (Freddie Mac).

As of March 31, 2021 and December 31, 2020, FHLBank did not recognize a provision for credit losses associated with available-for-sale investments or held-to-maturity investments. Although certain available-for-sale securities were in an unrealized loss position, these losses are considered temporary as FHLBank expects to recover the entire amortized cost basis on these available-for-sale investment securities. FHLBank neither intends to sell these securities nor considers it more likely than not that it will be required to sell these securities before its anticipated recovery of each security's remaining amortized cost basis. Further, FHLBank has not experienced any payment defaults on the instruments, and all of these securities carry an implicit or explicit government guarantee. FHLBank's held-to-maturity securities: (1) were all highly-rated and/or had short remaining terms to maturity; (2) had not experienced, nor did FHLBank expect, any payment default on the instruments; and (3) in the case of U.S. obligations or GSE debentures, carry an implicit or explicit government guarantee such that FHLBank considers the risk of nonpayment to be zero.

Advances [Abstract]
Advances	ADVANCES General Terms: 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, 2021 and December 31, 2020, FHLBank had advances outstanding at interest rates ranging from 0.11 percent to 7.20 percent. Table 4.1 presents advances summarized by redemption term as of March 31, 2021 and December 31, 2020 (dollar amounts in thousands). Carrying amounts exclude accrued interest receivable of $14,046,000 and $15,588,000 as of March 31, 2021 and December 31, 2020, respectively.

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 FHLBank to convert an advance from one interest payment term structure to another. When issuing convertible advances, FHLBank purchases put options from a member that allow 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. In October 2020, FHLBank placed a moratorium on the issuance of convertible advances; however, $1,596,200,000 remain outstanding.

This approach includes an ongoing review of each borrower's financial condition, in conjunction with FHLBank's collateral and lending policies to limit risk of loss, while balancing borrowers' needs for a reliable source of funding. Using a risk-based approach and taking into consideration each borrower's financial strength, FHLBank considers the types and level of collateral to be the primary indicator of credit quality on advances. As of March 31, 2021 and December 31, 2020, FHLBank had rights to collateral on a borrower-by-borrower basis with an estimated value greater than its outstanding advances. FHLBank continues to evaluate and make changes to its collateral guidelines, as necessary, based on current market conditions. As of March 31, 2021 and December 31, 2020, no advances were past due, on non-accrual status, or considered impaired. In addition, there were no troubled debt restructurings related to advances during the three months ended March 31, 2021 and 2020. Based on the collateral held as security, FHLBank's credit extension and collateral policies, and repayment history on advances, no losses are expected on advances as of March 31, 2021 and December 31, 2020, and therefore no allowance for credit losses on advances was recorded.

Allowance for Credit Losses: Conventional Mortgage Loans: Conventional loans are evaluated collectively when similar risk characteristics exist. Conventional loans that do not share risk characteristics with other pools are evaluated for expected credit losses on an individual basis. FHLBank determines its allowances for credit losses on conventional loans through analyses that include consideration of various loan portfolio and collateral-related characteristics, such as past performance, current conditions, and reasonable and supportable forecasts of expected economic conditions. FHLBank uses a model that discounts projected cash flows to estimate expected credit losses over the life of the loans. This model relies on a number of inputs, such as both current and forecasted property values and interest rates as well as historical borrower behavior experience. FHLBank also incorporates associated credit enhancements, as available, to determine its estimate of expected credit losses. Certain conventional loans may be evaluated for credit losses using the practical expedient for collateral dependent assets. A mortgage loan is considered collateral dependent if repayment is expected to be provided by the sale of the underlying property, that is, if it is considered likely that the borrower will default. FHLBank may estimate the fair value of this collateral by applying an appropriate loss severity rate or using third party estimates or property valuation model(s). The expected credit loss of a collateral dependent mortgage loan is equal to the difference between the amortized cost of the loan and the estimated fair value of the collateral, less estimated selling costs. FHLBank records a direct charge-off of the loan balance if certain triggering criteria are met. Expected recoveries of prior charge-offs, if any, are included in the allowance for credit losses. FHLBank established an allowance for credit losses on its conventional mortgage loans held for portfolio. Table 5.5 presents a roll-forward of the allowance for credit losses on mortgage loans for the three months ended March 31, 2021 and 2020.

For uncleared derivative transactions, 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. 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. FHLBank was not required to post additional initial margin by its clearing agents as of March 31, 2021 and December 31, 2020. FHLBank’s net exposure on derivative agreements is presented in Note 9.

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, FHLBank also enters into interest rate swap agreements (in which 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 FHLBank to obtain attractively priced variable rate financing.

Offsetting [Abstract]
Assets and Liabilities Subject to Offsetting	ASSETS AND LIABILITIES SUBJECT TO OFFSETTING 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, FHLBank has elected to offset its asset and liability positions, as well as cash collateral received or pledged, including associated accrued interest. 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, FHLBank presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse. Tables 9.1 and 9.2 present the fair value of financial assets, including the related collateral received from or pledged to clearing agents or counterparties, based on the terms of FHLBank’s master netting arrangements or similar agreements as of March 31, 2021 and December 31, 2020 (in thousands): Table 9.1 03/31/2021 Description Gross Amounts Gross Amounts Net Amounts Gross Amounts Not Offset in the Statement of Condition 1 Net Derivative assets: Uncleared derivatives $ 15,209 $ (10,288) $ 4,921 $ (42) $ 4,879 Cleared derivatives 4,240 148,791 153,031 — 153,031 Total derivative assets 19,449 138,503 157,952 (42) 157,910 Securities purchased under agreements to resell 1,700,000 — 1,700,000 (1,700,000) — TOTAL $ 1,719,449 $ 138,503 $ 1,857,952 $ (1,700,042) $ 157,910 1 Represents noncash collateral received on financial instruments that: (1) do not qualify for netting on the Statements of Condition; or (2) are not subject to an enforceable netting agreement (e.g., mortgage delivery commitments).

Stockholders' Equity Note [Abstract]
Capital	CAPITAL Capital Requirements: FHLBank is subject to three capital requirements under the provisions of the Gramm-Leach-Bliley Act (GLB Act) and the FHFA's capital structure regulation. Regulatory capital does not include AOCI but does include mandatorily redeemable capital stock. • Risk-based capital. 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 FHLBank to satisfy its risk-based capital requirement. The FHFA may require 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 FHLBank to date. • Total regulatory capital. The GLB Act requires 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. 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 10.1 illustrates that FHLBank was in compliance with its regulatory capital requirements as of March 31, 2021 and December 31, 2020 (dollar amounts in thousands): Table 10.1 03/31/2021 12/31/2020 Required Actual Required Actual Regulatory capital requirements: Risk-based capital $ 349,751 $ 2,243,877 $ 192,927 $ 2,213,868 Total regulatory capital-to-asset ratio 4.0 % 5.4 % 4.0 % 5.0 % Total regulatory capital $ 1,940,017 $ 2,621,024 $ 2,103,668 $ 2,627,083 Leverage capital ratio 5.0 % 7.7 % 5.0 % 7.1 % Leverage capital $ 2,425,021 $ 3,742,963 $ 2,629,586 $ 3,734,017 Capital Stock: FHLBank offers two classes of stock, Class A Common Stock and Class B Common Stock. Each member is required to hold capital stock to become and remain a member of FHLBank (Asset-based Stock Purchase Requirement; Class A Common Stock) and enter into specified activities with FHLBank including, but not limited to, access to FHLBank’s credit products and selling Acquired Member Assets (AMA) to FHLBank (Activity-based Stock Purchase Requirement; Class A Common Stock to the extent of a member’s Asset-based Stock Purchase Requirement, then Class B Common Stock for the remainder). The amount of Class A Common Stock a member must acquire and maintain is the Asset-based Stock Purchase Requirement, which is currently equal to 0.1 percent of a member’s total assets as of December 31 of the preceding calendar year, with a minimum requirement of $1,000, and a maximum requirement of $500,000. The amount of Class B Common Stock a member must acquire and maintain is the Activity-based Stock Purchase Requirement, which is currently equal to 4.5 percent of the principal amount of advances outstanding to the member plus 3.0 percent of the principal amount of AMA outstanding for the member, limited to a maximum of 3.0 percent of the member's total assets at the end of the prior calendar year, less the member’s Asset-based Stock Purchase Requirement. As of December 31, 2020, there was no Activity-based Stock Purchase Requirement for letters of credit. However, the Letter of Credit Activity-based Stock Purchase Requirement increased to 0.25 percent from the previous requirement of zero percent, effective January 22, 2021. The change in the Activity-based Stock Purchase Requirements did not change for former members with outstanding business transactions. Mandatorily Redeemable Capital Stock: FHLBank is a cooperative whose members own most of 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 FHLBank's Statements of Condition. Shares cannot be purchased or sold except between 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, 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 10.2 presents a roll-forward of mandatorily redeemable capital stock for the three months ended March 31, 2021 and 2020 (in thousands): Table 10.2 Three Months Ended 03/31/2021 03/31/2020 Balance, beginning of period $ 1,624 $ 2,415 Capital stock subject to mandatory redemption reclassified from equity during the period 358,243 305,957 Capital stock redemption cancellations reclassified to equity during the period — (100,647) Redemption or repurchase of mandatorily redeemable capital stock during the period (358,290) (205,359) Stock dividend classified as mandatorily redeemable capital stock during the period 8 24 Balance, end of period $ 1,585 $ 2,390 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 FHLBank to create excess member stock under certain circumstances. For example, FHLBank may not pay dividends in the form of capital stock or issue new excess stock to members if FHLBank’s excess stock exceeds one percent of its total assets or if the issuance of excess stock would cause FHLBank’s excess stock to exceed one percent of its total assets. As of March 31, 2021, 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, that FHLBank becomes subject to additional supervisory authority by the FHFA. Before implementing a reclassification, the Director of the FHFA is required to provide an FHLBank with written notice of the proposed action and an opportunity to submit a response. As of the most recent review by the FHFA, FHLBank Topeka was classified as adequately capitalized.

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 FHLBank using available market and other pertinent information and reflect 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 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, 2021 and December 31, 2020. Additionally, these values do not represent an estimate of the overall market value of 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 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. 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 FHLBank can access on the measurement date. An active market for the asset or liability is a market in which the transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. • 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. 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, 2021 and 2020. Tables 12.1 and 12.2 present the carrying value, fair value and fair value hierarchy of financial assets and liabilities as of March 31, 2021 and December 31, 2020. 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. 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 12.3 and 12.4. The carrying value, fair value and fair value hierarchy of FHLBank’s financial assets and liabilities as of March 31, 2021 and December 31, 2020 are summarized in Tables 12.1 and 12.2 (in thousands): Table 12.1 03/31/2021 Carrying Total Level 1 Level 2 Level 3 Netting Adjustment and Cash Collateral 1 Assets: Cash and due from banks $ 65,136 $ 65,136 $ 65,136 $ — $ — $ — Interest-bearing deposits 558,784 558,784 — 558,784 — — Securities purchased under agreements to resell 1,700,000 1,700,000 — 1,700,000 — — Federal funds sold 3,905,000 3,905,000 — 3,905,000 — — Trading securities 3,266,965 3,266,965 — 3,266,965 — — Available-for-sale securities 6,363,707 6,363,707 — 6,363,707 — — Held-to-maturity securities 2,567,175 2,571,789 — 2,495,799 75,990 — Advances 21,068,366 21,179,090 — 21,179,090 — — Mortgage loans held for portfolio, net of allowance 8,667,085 8,806,362 — 8,792,449 13,913 — Accrued interest receivable 93,123 93,123 — 93,123 — — Derivative assets 157,952 157,952 — 19,449 — 138,503 Liabilities: Deposits 1,262,945 1,262,945 — 1,262,945 — — Consolidated obligation discount notes 10,072,689 10,072,023 — 10,072,023 — — Consolidated obligation bonds 34,314,007 34,264,800 — 34,264,800 — — Mandatorily redeemable capital stock 1,585 1,585 1,585 — — — Accrued interest payable 45,254 45,254 — 45,254 — — Derivative liabilities 3,006 3,006 — 221,743 — (218,737) Other Asset (Liability): Industrial revenue bonds 35,000 36,534 — 36,534 — — Financing obligation payable (35,000) (36,534) — (36,534) — — 1 Represents the effect of legally enforceable master netting agreements that allow 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	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 $652,020,742,000 and $698,296,045,000 as of March 31, 2021 and December 31, 2020, respectively. Off-balance Sheet Commitments: As of March 31, 2021 and December 31, 2020, off-balance sheet commitments are presented in Table 13.1 (in thousands): Table 13.1 03/31/2021 12/31/2020 Notional Amount Expire Expire Total Expire Expire Total Standby letters of credit outstanding $ 5,202,777 $ 692 $ 5,203,469 $ 5,436,165 $ 4,251 $ 5,440,416 Advance commitments outstanding 18,632 16,901 35,533 19,693 21,001 40,694 Principal commitments for standby bond purchase agreements 304,055 434,415 738,470 380,615 317,710 698,325 Commitments to fund or purchase mortgage loans 191,878 — 191,878 133,456 — 133,456 Commitments to issue consolidated bonds, at par 215,000 — 215,000 4,000 — 4,000 Commitments to Extend Credit: 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 at the time of issuance with assets allowed by 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 FHLBank is required to make payment for a beneficiary's draw, the member either reimburses FHLBank for the amount drawn or, subject to 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. Outstanding standby letters of credit have original or extended expiration periods of up to 6 years. FHLBank's current outstanding standby letters of credit expire 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 $1,328,000 and $1,554,000 as of March 31, 2021 and December 31, 2020, respectively. Advance commitments legally bind and unconditionally obligate 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, FHLBank does not expect to incur any credit losses on the outstanding letters of credit or advance commitments. Standby Bond-Purchase Agreements: FHLBank has entered into standby bond purchase agreements with state housing authorities whereby 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 FHLBank to purchase the bond and typically allows FHLBank to terminate the agreement upon the occurrence of a default event of the issuer. The bond purchase commitments entered into by FHLBank expire no later than 2024, though some are renewable at the option of FHLBank. As of March 31, 2021 and December 31, 2020, the total commitments for bond purchases included agreements with two in-district state housing authorities. FHLBank was required to purchase $122,390,000 in bonds under these agreements during the three months ended March 31, 2020. These bonds were classified as available-for-sale securities, and were acquired at par and sold at par within the same month. FHLBank was not required to purchase any bonds under any agreements during the three months ended March 31, 2021. Commitments to Purchase Mortgage Loans: These commitments that unconditionally obligate 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. FHLBank recorded mortgage delivery commitment net derivative asset (liability) balances of $(954,000) and $650,000 as of March 31, 2021 and December 31, 2020, respectively. Commitments to Issue Consolidated Obligations: 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 FHLBank is a cooperative whose members own most of the capital stock of 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. 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 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, FHLBank defines related parties as FHLBank directors’ financial institutions and members with capital stock investments in excess of 10 percent of FHLBank’s total regulatory capital stock outstanding, which includes mandatorily redeemable capital stock. Activity with Members that Exceed a 10 Percent Ownership in FHLBank Regulatory Capital Stock: Tables 14.1 and 14.2 present information on members that owned more than 10 percent of outstanding FHLBank regulatory capital stock as of March 31, 2021 and December 31, 2020 (dollar amounts in thousands).

Accounting Policies [Abstract]
Basis of Presentation, Policy	Basis of Presentation: The accompanying interim financial statements of 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 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. 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, 2020. The interim financial statements presented herein should be read in conjunction with FHLBank’s audited financial statements and notes thereto, which are included in FHLBank’s annual report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 18, 2021 (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, 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 and the fair value of derivatives. 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.
New Accounting Pronouncements, Policy	Reference Rate Reform (Accounting Standards Update (ASU) 2021-01). In January 2021, the Financial Accounting Standards Board (FASB) issued an amendment that refines the scope of Accounting Standards Codification (ASC) 848 and clarifies the guidance issued to facilitate the effects of reference rate reform on financial reporting. The amendment permits entities to elect certain optional expedients and exceptions when accounting for derivative contracts and certain hedging relationships affected by changes in the interest rates used for discounting cash flows, computing variation margin settlements and calculating price alignment interest in connection with reference rate reform activities. During the fourth quarter of 2020, FHLBank elected applicable optional expedients specific to discounting transition on a retrospective basis. As a result of electing this expedient, discounting transition did not have a material effect on FHLBank's financial condition, results of operations, or cash flows. This guidance was effective immediately for FHLBank and was applied consistently with the optional expedient guidance under ASU 2020-04, described below. Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04) . In March 2020, the FASB issued temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The transactions primarily include: (1) contract modifications; (2) hedging relationships; and (3) sale or transfer of debt securities classified as held-to-maturity. During the second quarter of 2021, FHLBank adopted a provision of ASU 2020-04 which allows a one-time election to sell, transfer, or both sell and transfer debt securities classified as held-to-maturity that reference a rate affected by reference rate reform and that were classified as held-to-maturity before January 1, 2020. See Note 15 - Subsequent Events for additional information related to this transfer. This guidance was effective immediately for FHLBank, and the amendments may be applied prospectively through December 31, 2022. FHLBank is in the process of evaluating the guidance and the other optional expedients, and the effect on FHLBank's financial condition, results of operations and cash flows has not yet been determined.
Credit Loss, Financial Instrument, Policy	Interest-Bearing Deposits, Securities Purchased under Agreements to Resell, and Federal Funds Sold: FHLBank invests in interest-bearing deposits, securities purchased under agreements to resell, and Federal funds sold to provide short-term liquidity. These investments are generally transacted with counterparties that have received a credit rating of triple-B or greater (investment grade) by a Nationally Recognized Statistical Ratings Organization (NRSRO). These may differ from internal ratings of the investments, if applicable. As of March 31, 2021, approximately 28 percent of these overnight investments were with counterparties not rated by an NRSRO. All transactions with unrated counterparties are secured transactions. Federal funds sold are unsecured loans that are generally transacted on an overnight term. Federal Housing Finance Agency (FHFA) regulations include a limit on the amount of unsecured credit FHLBank may extend to a counterparty. As of March 31, 2021 and December 31, 2020, all investments in interest-bearing deposits and Federal funds sold were repaid or expected to be repaid according to the contractual terms. No allowance for credit losses was recorded for these assets as of March 31, 2021 and December 31, 2020. Carrying values of interest-bearing deposits and Federal funds sold exclude accrued interest receivable of $60,000 and $5,000, respectively, as of March 31, 2021, and $80,000 and $3,000, respectively, as of December 31, 2020. Securities purchased under agreements to resell are short-term and are structured such that they are evaluated regularly to determine if the market value of the underlying securities decreases below the market value required as collateral (i.e., subject to collateral maintenance provisions). Based upon the collateral held as security and collateral maintenance provisions with its counterparties, FHLBank determined that no allowance for credit losses was needed for its securities purchased under agreements to resell as of March 31, 2021 and December 31, 2020. The carrying value of securities purchased under agreements excludes accrued interest receivable of $3,000 and $6,000 as of March 31, 2021 and December 31, 2020, respectively. Allowance for Credit Losses on Available-for-Sale and Held-to-Maturity Securities: FHLBank evaluates available-for-sale and held-to-maturity investment securities for credit losses on a quarterly basis. As of March 31, 2021 and December 31, 2020, FHLBank did not recognize a provision for credit losses associated with available-for-sale investments or held-to-maturity investments. Although certain available-for-sale securities were in an unrealized loss position, these losses are considered temporary as FHLBank expects to recover the entire amortized cost basis on these available-for-sale investment securities. FHLBank neither intends to sell these securities nor considers it more likely than not that it will be required to sell these securities before its anticipated recovery of each security's remaining amortized cost basis. Further, FHLBank has not experienced any payment defaults on the instruments, and all of these securities carry an implicit or explicit government guarantee. FHLBank's held-to-maturity securities: (1) were all highly-rated and/or had short remaining terms to maturity; (2) had not experienced, nor did FHLBank expect, any payment default on the instruments; and (3) in the case of U.S. obligations or GSE debentures, carry an implicit or explicit government guarantee such that FHLBank considers the risk of nonpayment to be zero. Allowance for Credit Losses: Conventional Mortgage Loans: Conventional loans are evaluated collectively when similar risk characteristics exist. Conventional loans that do not share risk characteristics with other pools are evaluated for expected credit losses on an individual basis. FHLBank determines its allowances for credit losses on conventional loans through analyses that include consideration of various loan portfolio and collateral-related characteristics, such as past performance, current conditions, and reasonable and supportable forecasts of expected economic conditions. FHLBank uses a model that discounts projected cash flows to estimate expected credit losses over the life of the loans. This model relies on a number of inputs, such as both current and forecasted property values and interest rates as well as historical borrower behavior experience. FHLBank also incorporates associated credit enhancements, as available, to determine its estimate of expected credit losses. Certain conventional loans may be evaluated for credit losses using the practical expedient for collateral dependent assets. A mortgage loan is considered collateral dependent if repayment is expected to be provided by the sale of the underlying property, that is, if it is considered likely that the borrower will default. FHLBank may estimate the fair value of this collateral by applying an appropriate loss severity rate or using third party estimates or property valuation model(s). The expected credit loss of a collateral dependent mortgage loan is equal to the difference between the amortized cost of the loan and the estimated fair value of the collateral, less estimated selling costs. FHLBank records a direct charge-off of the loan balance if certain triggering criteria are met. Expected recoveries of prior charge-offs, if any, are included in the allowance for credit losses.
Finance, Loan and Lease Receivables, Held-for-investment, Allowance and Nonperforming Loans, Nonperforming Loans Policy	Conventional Mortgage Loans: Conventional loans are evaluated collectively when similar risk characteristics exist. Conventional loans that do not share risk characteristics with other pools are evaluated for expected credit losses on an individual basis. FHLBank determines its allowances for credit losses on conventional loans through analyses that include consideration of various loan portfolio and collateral-related characteristics, such as past performance, current conditions, and reasonable and supportable forecasts of expected economic conditions. FHLBank uses a model that discounts projected cash flows to estimate expected credit losses over the life of the loans. This model relies on a number of inputs, such as both current and forecasted property values and interest rates as well as historical borrower behavior experience. FHLBank also incorporates associated credit enhancements, as available, to determine its estimate of expected credit losses. Certain conventional loans may be evaluated for credit losses using the practical expedient for collateral dependent assets. A mortgage loan is considered collateral dependent if repayment is expected to be provided by the sale of the underlying property, that is, if it is considered likely that the borrower will default. FHLBank may estimate the fair value of this collateral by applying an appropriate loss severity rate or using third party estimates or property valuation model(s). The expected credit loss of a collateral dependent mortgage loan is equal to the difference between the amortized cost of the loan and the estimated fair value of the collateral, less estimated selling costs. FHLBank records a direct charge-off of the loan balance if certain triggering criteria are met. Expected recoveries of prior charge-offs, if any, are included in the allowance for credit losses.
Derivatives, Offsetting Fair Value Amounts, Policy	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, FHLBank has elected to offset its asset and liability positions, as well as cash collateral received or pledged, including associated accrued interest. 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, 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	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.
