Federal Reserve made $9 trillion in emergency loans - Dec. 1, 2010
"The details of which banks participated in the Fed's emergency programs, and how the banks benefited from the transactions, had never before been revealed.
The Fed argued that revealing the information could cause a run on the banks that needed to draw cash at the discount window. But under the financial regulatory reform act that was passed in July, the Fed will reveal future discount window transactions following a two-year lag."
