Fannie and Freddie destroyed the housing market; taxpayers will pay as much as $1 trillion in "the mother of all bailouts"

The cost of fixing Fannie Mae and Freddie Mac, the mortgage companies that last year bought or guaranteed three-quarters of all U.S. home loans, will be at least $160 billion and could grow to as much as $1 trillion after the biggest bailout in American history.

Fannie and Freddie, now 80 percent owned by U.S. taxpayers, already have drawn $145 billion from an unlimited line of government credit granted to ensure that home buyers can get loans while the private housing-finance industry is moribund. That surpasses the amount spent on rescues of American International Group Inc., General Motors Co. or Citigroup Inc., which have begun repaying their debts.

“It is the mother of all bailouts,” said Edward Pinto, a former chief credit officer at Fannie Mae, who is now a consultant to the mortgage-finance industry.

Fannie, based in Washington, and Freddie in McLean, Virginia, own or guarantee 53 percent of the nation’s $10.7 trillion in residential mortgages, according to a June 10 Federal Reserve report. Millions of bad loans issued during the housing bubble remain on their books, and delinquencies continue to rise. How deep in the hole Fannie and Freddie go depends on unemployment, interest rates and other drivers of home prices, according to the companies and economists who study them.

The Congressional Budget Office calculated in August 2009 that the companies would need $389 billion in federal subsidies through 2019, based on assumptions about delinquency rates of loans in their securities pools. The White House’s Office of Management and Budget estimated in February that aid could total as little as $160 billion if the economy strengthens.

If housing prices drop further, the companies may need more. Barclays Capital Inc. analysts put the price tag as high as $500 billion in a December report on mortgage-backed securities, assuming home prices decline another 20 percent and default rates triple.

Sean Egan, president of Egan-Jones Ratings Co. in Haverford, Pennsylvania, said that a 20 percent loss on the companies’ loans and guarantees, along the lines of other large market players such as Countrywide Financial Corp., now owned by Bank of America Corp., could cause even more damage.

“One trillion dollars is a reasonable worst-case scenario for the companies,” said Egan, whose firm warned customers away from municipal bond insurers in 2002 and downgraded Enron Corp. a month before its 2001 collapse.
