Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 - Summary of Significant Accounting Policies Unless the context otherwise requires, the terms "we," "us," "our" and "Bank" refer to the Federal Home Loan Bank of Indianapolis or its management. We use acronyms and terms throughout these Notes to Financial Statements that are defined in the Defined Terms . Basis of Presentation. The accompanying interim financial statements have been prepared in accordance with GAAP and SEC requirements for interim financial information. Accordingly, they do not include all of the information and disclosures required by GAAP for complete financial statements. Certain disclosures that would have substantially duplicated the disclosures in the financial statements, and notes thereto, included in our 2023 Form 10-K have been omitted unless the information contained in those disclosures materially changed. Therefore, these interim financial statements should be read in conjunction with our audited financial statements, and notes thereto, included in our 2023 Form 10-K. The financial statements contain all adjustments that are, in the opinion of management, necessary for a fair statement of the Bank'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 calendar year or any other interim period. Use of Estimates. When preparing financial statements in accordance with GAAP, we are required to make subjective assumptions and estimates that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expense. Although the reported amounts and disclosures reflect our best estimates, actual results could differ significantly from these estimates. The most significant estimates pertain to the fair values of financial instruments, specifically our derivatives and associated hedged items. Significant Accounting Policies. Our significant accounting policies and certain other disclosures are set forth in our 2023 Form 10-K in Note 1 - Summary of Significant Accounting Policies .

Realized Gains and Losses. There were no sales of HTM securities during the three and six months ended June 30, 2024. During the six months ended June 30, 2023, we sold a portion of our HTM MBS for which we had previously collected at least 85% of the principal outstanding at the time of acquisition. As such, the sales were considered maturities for purposes of security classification.

At June 30, 2024 and December 31, 2023, based on our evaluation of expected credit losses, no allowance for credit losses on any of our HTM securities was deemed necessary.
