The New York Federal Reserve said on Friday it bought $1.970 billion of U.S. agency debt with maturities ranging from April 2016 to March 2019.

Dealers submitted $4.378 billion of agency debt for consideration in the purchase.

Friday's operation brings the N.Y. Fed's cumulative purchase of agency debt to $81 billion since early December.

The Fed had said it would buy securities maturing between April 2016 and July 2032, but it opted not to buy any of the longest-term debt.

The N.Y. Fed, which conducts open market operations for the U.S. central bank, has said it would buy up to $200 billion of agency securities issued by Fannie Mae, Freddie Mac and the Federal Home Loan Bank system aiming to hold down mortgage rates and revive economic growth.
