Paul Krugman presents a fable of Wall St.
And in his fable he explains what went wrong on Wall St.
Underlying the glamorous new world of finance was the process of securitization. Loans no longer stayed with the lender. Instead, they were sold on to others, who sliced, diced and puréed individual debts to synthesize new assets. Subprime mortgages, credit card debts, car loans — all went into the financial system’s juicer. Out the other end, supposedly, came sweet-tasting AAA investments. And financial wizards were lavishly rewarded for overseeing the process.And with this fable he hopes to show us that it was not just a failure of regulation, but of the entire structure of the financial sector. Will anyone listen?
But the wizards were frauds, whether they knew it or not, and their magic turned out to be no more than a collection of cheap stage tricks. Above all, the key promise of securitization — that it would make the financial system more robust by spreading risk more widely — turned out to be a lie. Banks used securitization to increase their risk, not reduce it, and in the process they made the economy more, not less, vulnerable to financial disruption.
Sooner or later, things were bound to go wrong, and eventually they did. Bear Stearns failed; Lehman failed; but most of all, securitization failed.
