Since President Barack Obama was inaugurated in January 2009, the Federal Reserve’s holdings of U.S. government debt have quintupled, according to the Fed’s official monthly balance sheet.

On Jan. 28, 2009, a week after Obama’s nomination, the Fed owned $302 billion in U.S. Treasury securities. On April 25, 2012, the latest date reported, the Fed owned five and a half time that much in U.S. Treasury securities--$1.668 trillion.

That is an increase from January 2009 of $1.366 trillion—or 452 percent.
