Basis of Presentation [Abstract]
Basis of Presentation [Text Block]	Basis of Presentation The accompanying interim financial statements of the FHLBank have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The preparation of financial statements in accordance with GAAP requires management to make assumptions and estimates. These assumptions and estimates affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expenses. Actual results could differ from these estimates. The interim financial statements presented are unaudited, but they include all adjustments (consisting of only normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the financial condition, results of operations, and cash flows for such periods. These financial statements do not include all disclosures associated with annual financial statements and accordingly should be read in conjunction with the audited financial statements and notes included in the FHLBank's annual report on Form 10-K for the year ended December 31, 2012 filed with the Securities and Exchange Commission (SEC). Results for the three months ended March 31, 2013 are not necessarily indicative of operating results for the full year. The FHLBank has evaluated subsequent events for potential recognition or disclosure through the issuance of these financial statements and believes there have been no material subsequent events requiring additional disclosure or recognition in these financial statements.
