Early Friday, the Treasury said it would offer $50 billion from its Exchange Stabilization Fund to insure money-market mutual funds. A number of such funds have lately been under fire thanks to investment in bad debt from bankrupt Lehman Brothers and flailing insurer AIG ( AIG). The Federal Reserve also said it would build on its liquidity programs to assist money-market funds, by taking steps that include buying short-term debt issued by Fannie Mae ( FNM), Freddie Mac ( FRE) and the Federal Home Loan Banks. Speaking at a press conference Friday morning, Treasury Secretary Henry Paulson said that government-sponsored entities Fannie Mae and Freddie Mac would continue to buy mortgage-backed securities and support the mortgage market. He also said that the Treasury will expand its program to purchase mortgage-backed securities. He said that the cost of government intervention would reach the hundreds of billions of dollars and the administration would work over the weekend to iron out details of the plan.
