Triple A Rating Fed the Con Game at AIG

The NY Times spells out how the insurance giant took us for a ride:

When you start asking around about how A.I.G. made money during the housing bubble, you hear the same two phrases again and again: “regulatory arbitrage” and “ratings arbitrage.” The word “arbitrage” usually means taking advantage of a price differential between two securities .... When the word is used to describe A.I.G.’s actions, however, it means something entirely different. It means taking advantage of a loophole in the rules. A less polite but perhaps more accurate term would be “scam.”

As a huge multinational insurance company, with a storied history and a reputation for being extremely well run, A.I.G. had one of the most precious prizes in all of business: an AAA rating, held by no more than a dozen or so companies in the United States ....

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.
