NEW YORK (Reuters) - The Federal Reserve on Friday awarded $113.43 billion of four-day, fixed-rate reverse repurchase agreements to 51 bidders at an interest rate of 0.25 percent, the New York Fed said on its website.

On Thursday, the Fed allotted $278.81 billion in one-day reverse repos to 92 bidders, including Wall Street dealers, money market mutual funds and mortgage finance agencies, also at an interest rate of 0.25 percent.

The reverse repurchase agreement program is seen as a critical policy tool for the U.S. central bank to drain money from the financial system in an effort to achieve its interest rate objectives.
