Treasury: Will begin selling mortgage securities

The Treasury Department announced Monday that it will begin selling its remaining $142 billion in holdings of mortgage-backed securities purchased during the financial crisis.

Treasury officials said the first sales of up to $10 billion in the securities, primarily issued by troubled mortgage companies Fannie Mae and Freddie Mac, would start this month.

Assistant Treasury Secretary Mary Miller said that the sales represented a continuation of efforts by the government to wind down the emergency programs put in place in 2008 and 2009 to help restore market stability.

Treasury estimated it could make a profit of $15 billion to $20 billion on its holdings, depending on market conditions.

"We will exit this investment at a gradual and orderly pace to maximize the recovery of taxpayer dollars and help protect the process of repair of the housing finance market," Miller said in a statement.

Treasury acquired its holdings of mortgage-backed securities after the government took over Fannie and Freddie in September 2008 at the height of the financial crisis. The program was designed to stabilize the market for mortgage-backed securities, which investors had started to flee as defaults in the mortgage market began to escalate. Treasury announced in December 2009 that it was halting the purchase of new securities under the program. At the time it had purchased a total of $220 billion worth of mortgage-backed securities.

Treasury said in its announcement Monday that the market for mortgage-backed securities had "notably improved" since 2008 and 2009.

In a fact sheet, Treasury said it planned to sell up to $10 billion of its $142 billion in mortgage-backed securities per month. At this pace, Treasury said the whole portfolio would be disposed of in about one year. But Treasury said if market conditions change, it is possible it will take longer to fully exit from the program.

Treasury said it believed the sales could take place with a "minimal impact" on home mortgage rates.

Treasury said that the announcement to sell the remaining holdings of mortgage-backed securities was not related to the impending battle over the debt limit. Treasury's latest estimate is that the government will reach the current $14.3 trillion borrowing limit between April 15 and May 31.

Republicans are demanding steeper cuts in government spending before they will agree to raise the debt limit. Treasury Secretary Timothy Geithner has warned that failure to raise the borrowing limit would trigger an unprecedented default by the government on the national debt which would drive up the government's borrowing costs.
