In Congressional testimony, William B. Shear, an official with the Government Accountability Office, warned that Fannie and Freddie, “with more than $6 trillion in outstanding obligations,” could pose “significant risks to taxpayers” if they ran into difficulty.
Each of the two enterprises has a $2.25 billion line of credit with the Treasury, but that is a small fraction of what they owe. Mr. Shear said it was “generally assumed on Wall Street that assistance would be provided in a financial emergency.”
With the trading levels indicating that some traders were no longer as confident of that assumption as they had been, rumors swirled that the Treasury Department was preparing to issue an explicit guarantee of the debts of government-sponsored enterprises, or G.S.E.’s, to calm the market. A Treasury spokeswoman denied those rumors.
“The rumor of an explicit government guarantee for the G.S.E.’s speaks to the gravity of the current situation,” said Margaret Kerins, a strategist at RBS Greenwich Capital.
