You have to have car insurance, it's a legal requirement. So it occurred to me a long time ago that you could make some money selling very low-cost car insurance that (when you looked at the fine print) promised nothing, thus making a safe profit for the company, fooling the regulators and satisfying the cheapskate customer, all at the same time. Fine, till the regulators find out.
According to Karl Denninger today, this is exactly what's happened in the case of UBS insuring one of its mortgage debt packages against default losses. The insurer, it's alleged, has totally inadequate capital for the insurance it's undertaken, but the insurance suited UBS because it permitted the stinking package to be left off the balance sheet.
Oh, to be a lawyer now.
