a cheap ticket to a drama that looked virtually certain to happen. They created another presentation to give to themselves. "We're looking at the trade," said Charlie, "and we're thinking, like, this is too good to be true. Why the hell should I be able to buy CDSs on the triple-Bs [credit default swaps on the triple-B tranche of subprime mortgage bonds] at these levels? Who in their right mind is saying, 'Wow, I think I'll take two hundred basis points to take this risk?' It just seems like a ridiculously low price. It doesn't make sense." It was now early October 2006. A few months earlier, in June, national home prices, for the first time, had begun to fall. In five weeks, on November 29, the index of subprime mortgage bonds, called the ABX, would post its first interest-rate shortfall. The borrowers were failing to make interest payments sufficient to pay off the riskiest subprime bonds. The underlying mortgage loans were already going sour, and yet the prices of the bonds backed by the loans hadn't budged. "That was the part that was so weird," said Charlie. "They'd already started going bad. We just kept asking, 'Who the hell is taking the other side of this trade?' And the answer that kept coming back to us was, 'It's the CDOs.'" Which of course just raised another question: Who, or what, was a CDO?

Typically when they entered a new market--because they'd found some potential accident waiting to happen that seemed worth betting on--they found an expert to serve as a jungle guide. This market was so removed from their experience that it took them longer than usual to find help. "I had a vague idea what an ABS [asset-backed security] was," said Charlie. "But I had no idea what a CDO was." Eventually they figured out that language served a different purpose inside the bond market than it did in the outside world. Bond market terminology was designed less to convey meaning than to bewilder outsiders. Overpriced bonds were not "expensive" overpriced bonds were "rich," which almost made them sound like something you should buy. The floors of subprime mortgage bonds were not called floors--or anything else that might lead the bond buyer to form any sort of concrete image in his mind--but tranches. The bottom tranche--the risky ground floor--was not called the ground floor but the mezzanine, or the mezz, which made it sound less like a dangerous investment and more like a highly prized seat in a domed stadium. A CDO composed of nothing but the riskiest, mezzanine layer of subprime mortgages was not called a subprime-backed CDO but a "structured finance CDO." "There was so much confusion about the different terms," said Charlie. "In the course of trying to figure it out, we realize that there's a reason why it doesn't quite make sense to us. It's because it doesn't quite make sense."

The subprime mortgage market had a special talent for obscuring what needed to be clarified. A bond backed entirely by subprime mortgages, for example, wasn't called a subprime mortgage bond. It was called an ABS, or asset-backed security. When Charlie asked Deutsche Bank exactly what assets secured an asset-backed security, he was handed lists of abbreviations and more acronyms--RMBS, HELs, HELOCs, Alt-A--along with categories of credit he did not know existed ("midprime"). RMBS stood for residential mortgage-backed security. HEL stood for home equity loan. HELOC stood for home equity line of credit. Alt-A was just what they called crappy mortgage loans for which they hadn't even bothered to acquire the proper documents--to verify the borrower's income, say. "A" was the designation attached to the most creditworthy borrowers; Alt-A, which stood for "Alternative A-paper," meant an alternative to the most creditworthy, which of course sounds a lot more fishy once it is put that way. As a rule, any loan that had been turned into an acronym or abbreviation could more clearly be called a "subprime loan," but the bond market didn't want to be clear. "Midprime" was a kind of triumph of language over truth. Some crafty bond market person had gazed
