Paul Krugman: Revenge of the Glut

Remember the good old days, when we used to talk about the “subprime crisis” — and some even thought that this crisis could be “contained”? Oh, the nostalgia!

Today we know that subprime lending was only a small fraction of the problem. Even bad home loans in general were only part of what went wrong. We’re living in a world of troubled borrowers, ranging from shopping mall developers to European “miracle” economies. And new kinds of debt trouble just keep emerging.

How did this global debt crisis happen? Why is it so widespread? The answer, I’d suggest, can be found in a speech Ben Bernanke, the Federal Reserve chairman, gave four years ago. At the time, Mr. Bernanke was trying to be reassuring. But what he said then nonetheless foreshadowed the bust to come.
