The New York Federal Reserve will buy agency debt securities Monday at a buyback auction to be held between 10:30 a.m. EDT (1430 GMT) and 11 a.m. EDT.

This time around, the central bank will buy securities with maturities between April 2011 and February 2013.

Earlier this week, the Fed announced it was increasing its purchases of agency debt by an additional $100 billion.

Risk premiums on agnecy debt tightened one to three basis points on the short end after the announcement, according to data from TradeWeb.
