NY Fed: Permanent OMOs

The purchase or sale of Treasury securities on an outright basis adds or drains reserves available in the banking system. Such transactions are arranged on a routine basis to offset other changes in the Federal Reserve’s balance sheet in conjunction with efforts to maintain conditions in the market for reserves consistent with the federal funds target rate set by the Federal Open Market Committee (FOMC).

On March 18, 2009, the FOMC announced a longer-dated Treasury purchase program with a different operating goal, to help improve conditions in private credit markets.

On August 10, 2010, the FOMC directed the Open Market Trading Desk at the Federal Reserve Bank of New York to keep constant the Federal Reserve’s holdings of securities at their current level by reinvesting principal payments from agency debt and agency mortgage-backed securities in longer-term Treasury securities.

On November 3, 2010, the FOMC decided to expand the Federal Reserve's holdings of securities in the SOMA to promote a stronger pace of economic recovery and to help ensure that inflation, over time, is at levels consistent with its mandate.
