Paul Krugman: Bubbles and the Banks

Health care reform is almost (knock on wood) a done deal. Next up: fixing the financial system. I’ll be writing a lot about financial reform in the weeks ahead. Let me begin by asking a basic question: What should reformers try to accomplish?

A lot of the public debate has been about protecting borrowers. Indeed, a new Consumer Financial Protection Agency to help stop deceptive lending practices is a very good idea. And better consumer protection might have limited the overall size of the housing bubble.

But consumer protection, while it might have blocked many subprime loans, wouldn’t have prevented the sharply rising rate of delinquency on conventional, plain-vanilla mortgages. And it certainly wouldn’t have prevented the monstrous boom and bust in commercial real estate.
