What does the government do in light of the subprime mortgage debacle?

It makes more of them, of course:

What isn't well known is that a parallel subprime market has emerged over the past year -- all made possible by the Federal Housing Administration. This also won't end happily for taxpayers or the housing market.

Last year banks issued $180 billion of new mortgages insured by the FHA, which means they carry a 100% taxpayer guarantee. Many of these have the same characteristics as subprime loans: low downpayment requirements, high-risk borrowers, and in many cases shady mortgage originators. FHA now insures nearly one of every three new mortgages, up from 2% in 2006.

The financial results so far are not as dire as those created by the subprime frenzy of 2004-2007, but taxpayer losses are mounting on its $562 billion portfolio. According to Mortgage Bankers Association data, more than one in eight FHA loans is now delinquent -- nearly triple the rate on conventional, nonsubprime loan portfolios. Another 7.5% of recent FHA loans are in "serious delinquency," which means at least three months overdue.

The FHA is almost certainly going to need a taxpayer bailout in the months ahead. The only debate is how much it will cost. By law FHA must carry a 2% reserve (or a 50 to 1 leverage rate), and it is now 3% and falling. Some experts see bailout costs from $50 billion to $100 billion or more, depending on how long the recession lasts.
