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 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 bring in an additional $15 billion to $20 billion over what it paid for the $142 billion in mortgage-backed securities it currently holds. However, that amount would still leave the government with heavy losses from the rescue of Fannie and Freddie in September 2008.
The final cost of the bailout of the two companies has been estimated to be as high as $259 billion, making it by far the government's costliest rescue operation during the financial crisis.
Treasury has retained State Street Global Advisors to manage the sales of its mortgage-backed securities. Officials said they would post an accounting of the sales at the end of each month on Treasury's web site.
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.
