Rumors that monoline insurers, like M.B.I.A. and Ambac, were in serious trouble helped spark the vast market sell-off that prompted the Federal Reserve’s interest-rate cut two weeks ago, and, only a few days later, rumors of a government-orchestrated bailout of these companies set off a six-hundred-point rally in the Dow.
Monoline insurers do a straightforward job: they insure securities—guaranteeing, for instance, that if a bond defaults they’ll cover the interest and the principal... Unfortunately, a sleepy, straightforward business wasn’t good enough for the insurers. Like everyone else in recent years, they wanted to cash in on the housing and lending boom. In order to expand, they started insuring the complex securities that Wall Street created by packaging mortgages, including subprime ones, for investors. This was a lucrative business... but it rested on a false assumption: that the insurers knew how risky these securities really were. They didn’t. Instead, they gravely underestimated how likely the loans were to go bad, which meant that they didn’t charge enough for the insurance they were offering, and didn’t put away enough to cover the claims. They’re now on the hook for tens of billions of dollars in potential losses...
That’s why so many people on Wall Street are pushing for a bailout for the insurers. It may be an abandonment of free-market principles, but no one has ever accused the Street of putting principle above profit.
