The Federal Reserve on Wednesday sold $8.624 billion of Treasuries with maturities ranging from July 2012 through January 2013, the New York Fed said on its website.

A total of $93.04 billion of Treasuries were submitted in the sale, the New York Fed said.

The sale was part of the Fed's latest stimulus program, dubbed Operation Twist -- a $400 billion program that extends the maturity of the central bank's Treasuries holdings in a bid to lower mortgage rates and other long-term borrowing costs.
