The Big Short_ Inside the Doomsday Machine - Michael Lewis [83]
Upon their return from Las Vegas, they set out to pester the rating agencies, and the Wall Street people who gamed their models, for more information. "We were trying to figure out what, if anything, would make the ratings agencies downgrade," said Danny. In the process, they picked up more disturbing tidbits. They'd often wondered, for instance, why the rating agencies weren't more critical of bonds underpinned by floating-rate subprime mortgages. Subprime borrowers tended to be one broken refrigerator away from default. Few, if any, should be running the risk of their interest payment spiking up. As most of these loans were structured, however, the homeowner would pay a fixed teaser rate of, say, 8 percent for the first two years, and then, at the start of the third year, the interest rate would skyrocket to, say, 12 percent, and thereafter it would float at permanently high levels. It was easy to understand why originators like Option One and New Century preferred to make these sorts of loans: After two years the borrowers either defaulted or, if their home price had risen, refinanced. To them the default was a matter of indifference, as they kept none of the risk of the loan; the refinance was merely a chance to charge the borrower new fees. Bouncing between the rating agencies and people he knew in the subprime bond packaging business, Eisman learned that the rating agencies simply assumed that the borrower would be just as likely to make his payments when the interest rate on the loan was 12 percent as when it was 8 percent--which meant more cash flow for the bondholders. Bonds backed by floating-rate mortgages received higher ratings than bonds backed by fixed-rate ones--which was why the percentage of subprime mortgages with floating rates had risen, in the past five years, from 40 to 80.
A lot of these loans were now going bad, but subprime bonds weren't moving--because Moody's and S&P, disturbingly, still hadn't changed their official opinions of them. As an equity investor, FrontPoint Partners was covered by Wall Street stockbrokers. Eisman asked stock market salesmen at Goldman Sachs and Morgan Stanley and the others to bring over the bond people for a visit. "We always asked the same question," says Eisman. "'Where are the ratings agencies in all this?' And I'd always get the same reaction. It was a physical reaction because they didn't want to say it. It was a smirk." Digging deeper, he called S&P and asked what happened to default rates if real estate prices fell. The man at S&P couldn't say: Their model for home prices had no ability to accept a negative number. "They were just assuming home prices would keep going up," says Eisman.*
Eventually he'd hop onto the subway with Vinny and ride down to Wall Street to meet with a woman at S&P named Ernestine Warner. Warner worked as an analyst in the surveillance department. The surveillance department was meant to monitor subprime bonds and downgrade them if the loans that underpinned them went bad. The loans were going bad but the bonds weren't being downgraded--and so once again Eisman wondered if S&P knew something he did not. "When we shorted the bonds, all we had was the pool-level data," he said. The pool-level data gave you the general characteristics--the average FICO scores, the average loan-to-value ratios, the average number of no-doc loans, and so forth--but no view of the individual loans. The pool-level data told you, for example, that 25 percent of the home loans in some pool were insured, but not which loans--the ones likely to go bad or the ones less likely to. It was impossible to determine how badly the Wall Street firms had gamed the system. "We of course thought that the ratings agencies had more data than we had," said Eisman. "They didn't."
Ernestine Warner was working with the same rough information available to traders like Eisman. This was insane: The arbiter of the value of the bonds lacked access to relevant information about the bonds. "When we asked her why," said Vinny, "she said, 'The issuers won't give
