Great article in the
New York Times. A few interesting graphs:
To be sure, most of A.I.G. operated the way it always had, like a normal, regulated insurance company. (Its insurance divisions remain profitable today.) But one division, its “financial practices” unit in London, was filled with go-go financial wizards who devised new and clever ways of taking advantage of Wall Street’s insatiable appetite for mortgage-backed securities. Unlike many of the Wall Street investment banks, A.I.G. didn’t specialize in pooling subprime mortgages into securities. Instead, it sold credit-default swaps.
These exotic instruments acted as a form of insurance for the securities. In effect, A.I.G. was saying if, by some remote chance (ha!) those mortgage-backed securities suffered losses, the company would be on the hook for the losses. And because A.I.G. had that AAA rating, when it sprinkled its holy water over those mortgage-backed securities, suddenly they had AAA ratings too. That was the ratings arbitrage. “It was a way to exploit the triple A rating,” said Robert J. Arvanitis, a former A.I.G. executive who has since become a leading A.I.G. critic.
Why would Wall Street and the banks go for this? Because it shifted the risk of default from themselves to A.I.G., and the AAA rating made the securities much easier to market. What was in it for A.I.G.? Lucrative fees, naturally. But it also saw the fees as risk-free money; surely it would never have to actually pay up. Like everyone else on Wall Street, A.I.G. operated on the belief that the underlying assets — housing — could only go up in price.Read all of it - it's pretty nuts!
