Accounting Policies [Abstract]
BASIS OF PRESENTATION	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, 2023. 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 11, 2024 (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 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.

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 Segment Reporting (ASU 2023-07) . In July 2023, the FASB issued amendments to improve disclosures about a public entity’s reportable segments and addresses requests from investors and other allocations of capital for additional, more detailed information about a reportable segment’s expenses, including entities with a single reportable segment. The ASU is effective for FHLBank for the annual period ending December 31, 2024 and will be effective for interim periods beginning January 1, 2025. The adoption of this guidance is not expected to have a material effect on FHLBank’s disclosures.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	INVESTMENTS FHLBank's investment portfolio consists of interest-bearing deposits, securities purchased under agreements to resell, Federal funds sold, and debt securities. 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 Rating Organization (NRSRO). These may differ from internal ratings of the investments, if applicable. As of March 31, 2024, approximately 23 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. FHFA regulations include a limit on the amount of unsecured credit FHLBank may extend to a counterparty. As of March 31, 2024 and December 31, 2023, 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, 2024 and December 31, 2023. Carrying values of interest-bearing deposits and Federal funds sold exclude accrued interest receivable 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, 2024 and December 31, 2023. The carrying value of securities purchased under agreements to resell excludes accrued interest receivable 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, but FHLBank is not required to divest instruments that experience credit deterioration after their purchase.

As of March 31, 2024 and 2023, 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. FHLBank's held-to-maturity and available-for-sale 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; (3) in the case of U.S. obligations, carry an explicit government guarantee such that FHLBank considers the risk of nonpayment to be zero; and (4) in the case of GSE debentures or MBS, the securities are purchased under an assumption that the issuers’ obligation to pay principal and interest on those securities will be honored, taking into account their status as GSEs.

Advances [Abstract]
Advances	ADVANCES General Terms: FHLBank offers fixed and variable rate advance products with different maturities, interest rates, payment characteristics and optionality. As of March 31, 2024 and December 31, 2023, FHLBank had advances outstanding at interest rates ranging from 0.43 percent to 7.20 percent and 0.42 percent to 7.20 percent, respectively. Table 4.1 presents advances summarized by redemption term as of March 31, 2024 and December 31, 2023 (dollar amounts in thousands). The redemption term represents the period in which principal amounts are contractually due.

In exchange for receiving the right to call the advance on a predetermined call schedule, the borrower may pay a higher rate for the advance relative to an equivalent maturity, non-callable advance. The borrower generally exercises its call options on these advances when interest rates decline (fixed rate advances) or spreads change (adjustable rate advances). FHLBank also offers fixed rate advances that include a put option held by FHLBank (putable advances). On the date FHLBank exercises its put option, the borrower has the option to prepay the advance in full without a fee or roll into another advance product. A putable advance carries a lower interest rate than a comparable-maturity fixed rate advance without the put feature. FHLBank would generally exercise its put option when interest rates increase. Other advances are prepayable with a prepayment fee that makes FHLBank economically indifferent to the prepayment. 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. Convertible advances are no longer a current product offering; however, $113,400,000 remain outstanding at March 31, 2024.

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, 2024 and December 31, 2023, 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, 2024 and December 31, 2023, no advances were past due, on nonaccrual status, or considered impaired. 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, 2024 and December 31, 2023, 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 allowance for credit losses on conventional loans through analyses that include consideration of various loan portfolio and collateral-related characteristics, such as past performance, current economic conditions, and reasonable and supportable forecasts of expected economic conditions. FHLBank uses a third-party projected cash flow model 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. The forecasts used in the calculation of expected credit losses cover the contractual terms of the loans rather than a reversion to historical trends after a forecasted period. 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 when the borrower is experiencing financial difficulty and repayment is expected to be substantially through the sale of the underlying collateral. FHLBank may estimate the fair value of this collateral by applying an appropriate loss severity rate or by 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, 2024 and 2023. Table 5.5 Three Months Ended Conventional Loans 03/31/2024 03/31/2023 Balance, beginning of the period $ 5,531 $ 6,378 Net (charge-offs) recoveries (129) (140) Provision (reversal) for credit losses (200) (402) Balance, end of the period $ 5,202 $ 5,836 Government-Guaranteed or -Insured Mortgage Loans: FHLBank invests in fixed rate mortgage loans that are insured or guaranteed by the Federal Housing Administration, the Department of Veterans Affairs, the Rural Housing Service of the Department of Agriculture, and/or the Department of Housing and Urban Development. The servicer provides and maintains insurance or a guarantee from the applicable government agency. The servicer is responsible for compliance with all government agency requirements and for obtaining the benefit of the applicable guarantee or insurance with respect to defaulted government-guaranteed or -insured mortgage loans. Based on FHLBank's assessment of its servicers and the collateral backing the loans, the risk of loss was immaterial; consequently, no allowance for credit losses for government-guaranteed or -insured mortgage loans was recorded as of March 31, 2024 and December 31, 2023. Furthermore, none of these mortgage loans have been placed on nonaccrual status because of the U.S. government guarantee or insurance on these loans and the contractual obligation of the loan servicer to repurchase the loans when certain criteria are met.

Cash collateral received was $52,910,000 and $28,452,000 as of March 31, 2024 and December 31, 2023, respectively. FHLBank carries derivative instruments at fair value on its Statements of Condition. Changes in fair value of the derivative hedging instrument and the hedged item attributable to the hedged risk for designated fair value hedges are recorded in net interest income in the same line as the earnings effect of the hedged item. Gains (losses) on fair value hedges include unrealized changes in fair value as well as net interest settlements. For the three months ended March 31, 2024 and 2023, FHLBank recorded net gains (losses) on derivatives and the related hedged items in fair value hedging relationships and the impact of those derivatives on FHLBank’s net interest income as presented in Table 6.2 (in thousands): Table 6.2 Three Months Ended 03/31/2024 Interest Income/Expense Advances Available-for-sale Securities Consolidated Obligation Discount Notes Consolidated Obligation Bonds Total amounts presented in the Statements of Income $ 591,987 $ 190,059 $ 227,541 $ 623,540 Gains (losses) on fair value hedging relationships: Interest rate contracts: Derivatives 1 $ 194,890 $ 145,687 $ (3,054) $ (84,391) Hedged items 2 (117,039) (88,253) 713 6,947 NET GAINS (LOSSES) ON FAIR VALUE HEDGING RELATIONSHIPS $ 77,851 $ 57,434 $ (2,341) $ (77,444) Three Months Ended 03/31/2023 Interest Income/Expense Advances Available-for-sale Securities Consolidated Obligation Discount Notes Consolidated Obligation Bonds Total amounts presented in the Statements of Income $ 536,594 $ 116,836 $ 263,521 $ 461,882 Gains (losses) on fair value hedging relationships: Interest rate contracts: Derivatives 1 $ (78,806) $ (71,218) $ 16,658 $ 54,901 Hedged items 2 118,441 111,500 (25,891) (124,178) NET GAINS (LOSSES) ON FAIR VALUE HEDGING RELATIONSHIPS $ 39,635 $ 40,282 $ (9,233) $ (69,277) 1 Includes net interest settlements in interest income/expense. 2 Includes amortization/accretion on closed fair value relationships in interest income.

Bilateral derivative transactions executed on or after September 1, 2022, are subject to two-way initial margin requirements if aggregate uncleared derivative exposure to a counterparty exceeds a specified threshold. The initial margin is required to be held at a third-party custodian, and the secured party can only take ownership upon the occurrence of certain events, including an event of default due to bankruptcy, insolvency, or similar proceeding. As of March 31,2024, FHLBank was not required to pledge to or receive initial margin from bilateral derivative counterparties. 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, 2024 and December 31, 2023. FHLBank’s net exposure on derivative agreements is presented in Note 9.

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, 2024 and December 31, 2023 (in thousands): Table 9.1 03/31/2024 Description Gross Amounts Gross Amounts Net Amounts Gross Amounts Not Offset in the Statement of Condition 1 Net Derivative assets: Uncleared derivatives $ 173,821 $ (173,090) $ 731 $ (182) $ 549 Cleared derivatives 6,032 330,039 336,071 — 336,071 Total derivative assets 179,853 156,949 336,802 (182) 336,620 Securities purchased under agreements to resell 3,925,000 — 3,925,000 (3,925,000) — TOTAL $ 4,104,853 $ 156,949 $ 4,261,802 $ (3,925,182) $ 336,620 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 operational 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 the amounts paid-in for 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, 2024 and December 31, 2023 (dollar amounts in thousands): Table 10.1 03/31/2024 12/31/2023 Required Actual Required Actual Regulatory capital requirements: Risk-based capital $ 777,733 $ 3,614,791 $ 746,439 $ 3,730,738 Total regulatory capital-to-asset ratio 4.0 % 5.4 % 4.0 % 5.4 % Total regulatory capital $ 2,946,572 $ 3,959,691 $ 2,997,879 $ 4,009,870 Leverage capital ratio 5.0 % 7.8 % 5.0 % 7.8 % Leverage capital $ 3,683,215 $ 5,767,087 $ 3,747,349 $ 5,875,238 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. Table 10.2 presents a roll-forward of mandatorily redeemable capital stock for the three months ended March 31, 2024 and 2023 (in thousands): Table 10.2 Three Months Ended 03/31/2024 03/31/2023 Balance, beginning of period $ 247 $ 280 Capital stock subject to mandatory redemption reclassified from equity during the period 154,493 211,237 Redemption or repurchase of mandatorily redeemable capital stock during the period (154,537) (211,250) Stock dividend classified as mandatorily redeemable capital stock during the period 2 2 Balance, end of period $ 205 $ 269 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, 2024, 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 Values

Fair Values	3 Months Ended

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, 2024 and December 31, 2023. 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, and derivatives with embedded options are 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. Valuations are derived from techniques that use significant assumptions not observable in the market, which include pricing models, discounted cash flow models using an unobservable discount rate, or similar techniques. 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, 2024 and 2023. 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, 2024 and December 31, 2023. 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, 2024 and December 31, 2023 are summarized in Tables 12.1 and 12.2 (in thousands): Table 12.1 03/31/2024 Carrying Total Level 1 Level 2 Level 3 Netting Adjustment and Cash Collateral 1 Assets: Cash and due from banks $ 31,237 $ 31,237 $ 31,237 $ — $ — $ — Interest-bearing deposits 2,016,198 2,016,198 — 2,016,198 — — Securities purchased under agreements to resell 3,925,000 3,925,000 — 3,925,000 — — Federal funds sold 3,580,000 3,580,000 — 3,580,000 — — Trading securities 893,114 893,114 — 893,114 — — Available-for-sale securities 12,184,017 12,184,017 — 12,184,017 — — Held-to-maturity securities 257,236 253,938 — 218,698 35,240 — Advances 41,660,129 41,681,151 — 41,681,151 — — Mortgage loans held for portfolio, net of allowance 8,440,064 7,491,078 — 7,486,869 4,209 — Accrued interest receivable 259,092 259,092 — 259,092 — — Derivative assets 336,802 336,802 — 179,853 — 156,949 Liabilities: Deposits 846,628 846,627 — 846,627 — — Consolidated obligation discount notes 17,005,256 17,004,112 — 17,004,112 — — Consolidated obligation bonds 51,457,077 50,505,214 — 50,505,214 — — Mandatorily redeemable capital stock 205 205 205 — — — Accrued interest payable 335,993 335,993 — 335,993 — — Derivative liabilities 2,077 2,077 — 396,265 — (394,188) Other Asset (Liability): Industrial revenue bonds 35,000 32,436 — 32,436 — — Financing obligation payable (35,000) (32,436) — (32,436) — — 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 Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Joint and Several Liability: As provided in the 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 $1,103,431,356,000 and $1,134,003,465,000 as of March 31, 2024 and December 31, 2023, respectively. Off-balance Sheet Commitments: Table 13.1 presents off-balance sheet commitments at March 31, 2024 and December 31, 2023 (in thousands). No allowance for credit losses was recorded on these commitments at March 31, 2024 and December 31, 2023. Table 13.1 03/31/2024 12/31/2023 Notional Amount Expire Expire Total Expire Expire Total Standby letters of credit outstanding $ 7,500,827 $ 23,617 $ 7,524,444 $ 7,242,988 $ 5,670 $ 7,248,658 Advance commitments outstanding 22,636 1,000 23,636 48,526 3,615 52,141 Principal commitments for standby bond purchase agreements 86,845 904,980 991,825 283,220 716,295 999,515 Commitments to fund or purchase mortgage loans 58,625 — 58,625 41,641 — 41,641 Commitments to issue consolidated bonds, at par 770,000 — 770,000 1,300,000 — 1,300,000 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 and non-member housing associates 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. FHLBank's current outstanding standby letters of credit expire no later than 2027. Unearned fees as well as the value of the guarantees related to standby letters of credit are recorded in other liabilities and amounted to $2,451,000 and $2,367,000 as of March 31, 2024 and December 31, 2023, 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 2029, though some are renewable at the option of FHLBank. As of March 31, 2024 and December 31, 2023, the total commitments for bond purchases included agreements with two in-district state housing authorities. FHLBank was not required to purchase any bonds under any agreements during the three months ended March 31, 2024 and 2023. 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 balances of $181,000 and $128,000 as of March 31, 2024 and December 31, 2023, 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, 2024 and December 31, 2023 (dollar amounts in thousands).

During the first quarter of 2023, FHLBank Topeka transferred debt obligations with a par amount of $1,000,000,000 to another FHLBank. There were no transfers of debt obligations to other FHLBanks during the three months ended March 31, 2024.

BASIS OF PRESENTATION (Policies

BASIS OF PRESENTATION (Policies)	3 Months Ended
	Mar. 31, 2024
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, 2023. 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 11, 2024 (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 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	Segment Reporting (ASU 2023-07) . In July 2023, the FASB issued amendments to improve disclosures about a public entity’s reportable segments and addresses requests from investors and other allocations of capital for additional, more detailed information about a reportable segment’s expenses, including entities with a single reportable segment. The ASU is effective for FHLBank for the annual period ending December 31, 2024 and will be effective for interim periods beginning January 1, 2025. The adoption of this guidance is not expected to have a material effect on FHLBank’s disclosures.
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 Rating Organization (NRSRO). These may differ from internal ratings of the investments, if applicable. As of March 31, 2024, approximately 23 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. FHFA regulations include a limit on the amount of unsecured credit FHLBank may extend to a counterparty. As of March 31, 2024 and December 31, 2023, 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, 2024 and December 31, 2023. Carrying values of interest-bearing deposits and Federal funds sold exclude accrued interest receivable 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, 2024 and December 31, 2023. The carrying value of securities purchased under agreements to resell excludes accrued interest receivable 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, 2024 and 2023, 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. FHLBank's held-to-maturity and available-for-sale 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; (3) in the case of U.S. obligations, carry an explicit government guarantee such that FHLBank considers the risk of nonpayment to be zero; and (4) in the case of GSE debentures or MBS, the securities are purchased under an assumption that the issuers’ obligation to pay principal and interest on those securities will be honored, taking into account their status as GSEs. Credit Risk Exposure and Security Terms: 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 allowance for credit losses on conventional loans through analyses that include consideration of various loan portfolio and collateral-related characteristics, such as past performance, current economic conditions, and reasonable and supportable forecasts of expected economic conditions. FHLBank uses a third-party projected cash flow model 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. The forecasts used in the calculation of expected credit losses cover the contractual terms of the loans rather than a reversion to historical trends after a forecasted period. 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 when the borrower is experiencing financial difficulty and repayment is expected to be substantially through the sale of the underlying collateral. FHLBank may estimate the fair value of this collateral by applying an appropriate loss severity rate or by 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. Government-Guaranteed or -Insured Mortgage Loans: FHLBank invests in fixed rate mortgage loans that are insured or guaranteed by the Federal Housing Administration, the Department of Veterans Affairs, the Rural Housing Service of the Department of Agriculture, and/or the Department of Housing and Urban Development. The servicer provides and maintains insurance or a guarantee from the applicable government agency. The servicer is responsible for compliance with all government agency requirements and for obtaining the benefit of the applicable guarantee or insurance with respect to defaulted government-guaranteed or -insured mortgage loans. Based on FHLBank's assessment of its servicers and the collateral backing the loans, the risk of loss was immaterial; consequently, no allowance for credit losses for government-guaranteed or -insured mortgage loans was recorded as of March 31, 2024 and December 31, 2023. Furthermore, none of these mortgage loans have been placed on nonaccrual status because of the U.S. government guarantee or insurance on these loans and the contractual obligation of the loan servicer to repurchase the loans when certain criteria are met.
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 of Financial Instruments, Policy	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.
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.
