NEW YORK, Aug 29 (Reuters) - The U.S. Federal Reserve's balance sheet shrank in the latest week on lower holdings of mortgage-backed securities, Fed data released on Thursday showed.
The Fed's balance sheet liabilities, which are a broad gauge of its lending to the financial system, stood at $3.602 trillion on Aug. 28, down from $3.603 trillion on Aug. 21.
The Fed's holdings of Treasuries edged up to $2.024 trillion as of Wednesday, up from $2.012 trillion the previous week.
But the Fed's ownership of mortgage bonds guaranteed by Fannie Mae, Freddie Mac and the Government National Mortgage Association (Ginnie Mae) fell to $1.291 trillion from $1.303 trillion a week ago.
The Fed's holdings of debt issued by Fannie Mae, Freddie Mac and the Federal Home Loan Bank system totaled $65.713 billion, which was unchanged from the previous week.
The Fed's overnight direct loans to credit-worthy banks via its discount window averaged $21 million a day during the week, compared with $22 million a day the previous week.
