This bill, titled the Federal Reserve Transparency Act of 2025, mandates a comprehensive audit of the Board of Governors of the Federal Reserve System and all Federal Reserve banks. The legislation requires the Comptroller General of the United States to complete this audit within 12 months of the bill's enactment, explicitly overriding any existing statutory limitations on such reviews. This provision aims to enhance oversight of the nation's central banking system. Following the audit's completion, the Comptroller General must submit a detailed report to Congress within 90 days, outlining the findings, conclusions, and any recommended legislative or administrative actions. The bill also enacts significant amendments to title 31, United States Code, specifically repealing certain limitations on the scope of Federal Reserve audits. These changes ensure greater transparency by allowing a full examination of the Federal Reserve's operations and financial activities.
