On October 3, 2008, Section 128 of the Emergency Economic Stabilization Act of 2008 allowed the Federal Reserve banks to begin paying interest on excess reserve balances ("IOER") as well as required reserves. The Federal Reserve banks began doing so three days later. Banks had already begun increasing the amount of their money on deposit with the Fed at the beginning of September, up from about $10 billion total at the end of August, 2008, to $880 billion by the end of the second week of January, 2009. In comparison, the increase in reserve balances reached only $65 billion after September 11, 2001 before falling back to normal levels within a month. Former U.S. Treasury Secretary Henry Paulson's original bailout proposal under which the government would acquire up to $700 billion worth of mortgage-backed securities contained no provision to begin paying interest on reserve balances.
