Government regulators eased capital requirements for Freddie Mac and Fannie Mae on Wednesday. The move is meant to ease the housing crisis, but critics say it will cause the two overleveraged firms to hang themselves at the expense of taxpayers.

The Office of Federal Housing Enterprise Oversight, which oversees Freddie Mac and Fannie Mae, agreed to allow the two government-sponsored entities to reduce their mandatory cash cushion by a third. The plan is expected to free up $200 billion that will go to buying up more mortgages and mortgage securities.

This is the third consecutive step the government has taken to ensure the two firms will be able to take on more of the country’s bad mortgage debt. The first came when Congress raised the limits for the loans that Fannie and Freddie can buy or insure from $417,000 to $729,750. The second occurred March 1 when Fannie and Freddie were released from the combined $1.5 trillion cap on their mortgage investment holdings.

The initiatives taken recently by the government are controversial because it raises the risks the two companies will be allowed to take on. This in turn raises risks for taxpayers. Although Fannie and Freddie are publicly-traded companies, they enjoy the benefit of an implicit government guarantee. In other words, taxpayers will be expected to flip the bill if Fannie and Freddie ever fail. 

And the risk of failure is very real. In the fourth quarter of last year, the two GSEs were responsible for nearly 75 percent of the mortgage backed securities on the market. They are also losing money fast and expect to see more red ink in the future.

Fannie Mae posted a record $3.55 billion fourth quarter loss. Analysts believe the company’s credit losses will continue to rise this year and in 2009. Freddie Mac is in a similar position. The company reported a record $2.45 billion net loss during the same period.

James Lockhart, director of the Office of Federal Housing Enterprise Oversight, assured everyone at a news conference today that Freddie and Fannie are “safe and sound” and would remain that way.

Until recently, Lockhart has been firmly against loosening regulations for Fannie Mae and Freddie Mac. There has been some speculation that his rapid change of heart stems from political and lobbyist pressure.
