U.S. Treasury sells MBS portfolio for $25 billion profit

"The successful sale of these securities marks another important milestone in the wind down of the government's emergency financial crisis response efforts," Treasury's assistant secretary for financial markets, Mary Miller, said in a statement.

Treasury began selling the securities, which it had bought when the markets were under severe stress, last year and said it took in $250 billion in total for them in sales, principal and interest.
