The Big Short_ Inside the Doomsday Machine - Michael Lewis [9]
Eisman was now about to become noticeably more negatively disposed, in ways that, from the point of view of his employer, were financially counterproductive. "It was like he'd smelled something," said Vinny. "And he needed my help figuring out what it was he'd smelled." Eisman wanted to write a report that more or less damned the entire industry, but he needed to be more careful than usual. "You can be positive and wrong on the sell side," says Vinny. "But if you're negative and wrong you get fired." Ammunition to cause trouble had just arrived a few months earlier from Moody's: The rating agency now possessed, and offered for sale, all sorts of new information about subprime mortgage loans. While the Moody's database did not allow you to examine individual loans, it offered a general picture of the pools of loans underlying individual mortgage bonds: how many were floating-rate, how many of the houses borrowed against were owner-occupied. Most importantly: how many were delinquent. "Here's this database," Eisman said simply. "Go into that room. Don't come out until you've figured out what it means." Vinny had the feeling Eisman already knew what it meant.
Vinny was otherwise on his own. "I'm twenty-six years old," he says, "and I haven't really understood what mortgage-backed securities really are." Eisman didn't know anything about them either--he was a stock market guy, and Oppenheimer didn't even have a bond department. Vinny had to teach himself. When he was done, he had an explanation for the unpleasant odor wafting from the subprime mortgage industry that Eisman had detected. These companies disclosed their ever-growing earnings, but not much else. One of the many items they failed to disclose was the delinquency rate of the home loans they were making. When Eisman had bugged them for these, they'd pretended that the fact was irrelevant, as they had sold all the loans off to people who packaged them into mortgage bonds: The risk was no longer theirs. This was untrue. All retained some small fraction of the loans they originated, and the companies were allowed to book as profit the expected future value of those loans. The accounting rules allowed them to assume the loans would be repaid, and not prematurely. This assumption became the engine of their doom.
What first caught Vinny's eye were the high prepayments coming in from a sector called "manufactured housing." ("It sounds better than 'mobile homes.'") Mobile homes were different from the wheel-less kind: Their value dropped, like cars', the moment they left the store. The mobile home buyer, unlike the ordinary home buyer, couldn't expect to refinance in two years and take money out. Why were they prepaying so fast? Vinny asked himself. "It made no sense to me. Then I saw that the reason the prepayments were so high is that they were involuntary." "Involuntary prepayment" sounds better than "default." Mobile home buyers were defaulting on their loans, their mobile homes were being repossessed, and the people who had lent them money were receiving fractions of the original loans. "Eventually I saw that all the subprime sectors were either being prepaid or going bad at an incredible rate," said Vinny. "I was just seeing stunningly high delinquency rates in these pools." The interest rate on the loans wasn't high enough to justify the risk of lending to this particular slice of the American population. It was as if the ordinary rules of finance had been suspended in response to a social problem. A thought crossed his mind: How do you make poor people feel wealthy when wages are stagnant? You give them cheap loans.
To sift every pool of subprime mortgage loans took him six months, but when he was done he came out of the room and gave Eisman the news. All these subprime lending companies were growing so rapidly, and using such goofy accounting, that they could mask the fact that they had no real earnings, just illusory, accounting-driven, ones. They had the
