The Fed is already rather audited... from Bernanke's blog: The Fed is already thoroughly audited in the usual sense, by an independent inspector general and by an outside accounting firm (currently, Deloitte and Touche), and the resulting financial reports are made public online. Every security owned by the Fed, up to the detail of the identifying CUSIP number, is also available online. Moreover, the Government Accountability Office (GAO), which does in-depth reviews and analyses (“audits” of a different type) of government activities at the request of Congress, has wide latitude to review Fed operations, including supervision and regulation as well as other functions. For example, as required by the Dodd-Frank Act of 2010, the GAO conducted reviews of the Fed’s emergency lending programs during the crisis and of the Fed’s governance structure. Since the financial crisis, the GAO has done some 70 reviews of aspects of Fed operations. What other sorts of auditing do you want? It's also worth mentioning that the US Fed acts as central bank to the world -- US taxpayers are not on the hook for that $6T.
