In late 1994, Blythe Masters, a member of the J. P. Morgan swaps team, pitched the idea of selling the credit risk to the European Bank of Reconstruction and Development. So, if Exxon defaulted, the E.B.R.D. would be on the hook for it—and, in return for taking on the risk, would receive a fee from J. P. Morgan. Exxon would get its credit line, and J. P. Morgan would get to honor its client relationship but also to keep its credit lines intact for sexier activities. The deal was so new that it didn’t even have a name: eventually, the one settled on was “credit-default swap.”
So far, so good for J. P. Morgan. But the deal had been laborious and time-consuming, and the bank wouldn’t be able to make real money out of credit-default swaps until the process became streamlined and industrialized. The invention that allowed all this to happen was securitization. Traditionally, banking involves a case-by-case assessment of the risk of every loan, and it’s hard to industrialize that process. What securitization did was bundle together a package of these loans, and then rely on safety in numbers and the law of averages: even if some loans did default, the others wouldn’t, and would keep the stream of revenue going, thereby diffusing and minimizing the risk of default. So there would be two sources of revenue: one from the sale of the loans, and another from the steady flow of repayments. Then someone had the idea of dividing up the securities into different levels of risk—a technique called tranching—and selling them off accordingly, so that riskier tranches of debt would pay a higher rate of interest than safer ones. Bill Demchak, a “structured finance” star at J. P. Morgan, took the lead in creating bundles of credit-default swaps—insurance against default—and selling them to investors. The investors would get the streams of revenue, according to the risk-and-reward level they chose; the bank would get insurance against its loans, and fees for setting up the deal.
There was one final component to the J. P. Morgan team’s invention. The team set up a kind of offshore shell company, called a Special Purpose Vehicle, to fulfill the role supplied by the European Bank for Reconstruction and Development in the first credit-default swap. The shell company would assume $9.7 billion of J. P. Morgan’s risk (in this case, outstanding loans that the bank had made to some three hundred companies) and sell off that risk to investors, in the form of securities paying differing rates of interest. According to J. P. Morgan’s calculations, the underlying loans were so safe that it needed to collect only seven hundred million dollars in order to cover the $9.7-billion debt. In 1997, the credit agency Moodys agreed, and a whole new era in banking dawned. J. P. Morgan had found a way to shift risk off its books while simultaneously generating income from that risk, and freeing up capital to lend elsewhere. It was magic. The only thing wrong with it was the name, BISTRO, for Broad Index Secured Trust Offering, which made the new rocket-science financial instrument sound like a place you went to for steak frites. The market came to prefer a different term: “synthetic collateralized debt obligations.”
