I’M NOT A BIG ECONO-BLOGGER, but the Fannie Mae scandal seems to be falling through the cracks. At least, judging by this it’s not getting the attention it deserves:

For years, mortgage giant Fannie Mae has produced smoothly growing earnings. And for years, observers have wondered how Fannie could manage its inherently risky portfolio without a whiff of volatility. Now, thanks to Fannie’s regulator, we know the answer. The company was cooking the books. Big time.

We’ve looked closely at the 211-page report issued by the Office of Federal Housing Enterprise Oversight (Ofheo), and the details are more troubling than even the recent headlines. The magnitude of Fannie’s machinations is stunning, and in two key areas in particular they deserve to be better understood. By improperly delaying the recognition of income, it created a cookie jar of reserves. And by improperly classifying certain derivatives, it was able to spread out losses over many years instead of recognizing them immediately. . . .

Fannie Mae isn’t an ordinary company and this isn’t a run-of-the-mill accounting scandal. The U.S. government had no financial stake in the failure of Enron or WorldCom. But because of Fannie’s implicit subsidy from the federal government, taxpayers are on the hook if its capital cushion is insufficient to absorb big losses. Private profit, public risk.

Indeed.

UPDATE: More on problems with Fannie Mae, and Freddie Mac, here. Apparently people have been warning of this for a while.
