Dr. Doom

On Sept. 7, 2006, Nouriel Roubini, an economics professor at New York University, stood before an audience of economists at the International Monetary Fund and announced that a crisis was brewing. In the coming months and years, he warned, the United States was likely to face a once-in-a-lifetime housing bust, an oil shock, sharply declining consumer confidence and, ultimately, a deep recession. He laid out a bleak sequence of events: homeowners defaulting on mortgages, trillions of dollars of mortgage-backed securities unraveling worldwide and the global financial system shuddering to a halt. These developments, he went on, could cripple or destroy hedge funds, investment banks and other major financial institutions like Fannie Mae and Freddie Mac.

The audience seemed skeptical, even dismissive. As Roubini stepped down from the lectern after his talk, the moderator of the event quipped,


But Roubini was soon vindicated. In the year that followed, subprime lenders began entering bankruptcy, hedge funds began going under and the stock market plunged. There was declining employment, a deteriorating dollar, ever-increasing evidence of a huge housing bust and a growing air of panic in financial markets as the credit crisis deepened. By late summer, the Federal Reserve was rushing to the rescue, making the first of many unorthodox interventions in the economy, including cutting the lending rate by 50 basis points and buying up tens of billions of dollars in mortgage-backed securities. When Roubini returned to the I.M.F. last September, he delivered a second talk, predicting a growing crisis of solvency that would infect every sector of the financial system. This time, no one laughed.
