Krugman on 'Too Big to Fail'

Here's a bit from the latest NY Times op-ed by Paul Krugman:

It’s easy to see where concerns about banks that are “too big to fail” come from. In the face of financial crisis, the U.S. government provided cash and guarantees to financial institutions whose failure, it feared, might bring down the whole system. And the rescue operation was mainly focused on a handful of big players: A.I.G., Citigroup, Bank of America, and so on.

This rescue was necessary, but it put taxpayers on the hook for potentially large losses. And it also established a dangerous precedent: big financial institutions, we now know, will be bailed out in times of crisis. And this, it’s argued, will encourage even riskier behavior in the future, since executives at big banks will know that it’s heads they win, tails taxpayers lose.

The solution, say people like Mr. Volcker, is to break big financial institutions into units that aren’t too big to fail, making future bailouts unnecessary and restoring market discipline.

It’s a convincing-sounding argument, but I’m one of those people who doesn’t buy it.

Here’s how I see it. Breaking up big banks wouldn’t really solve our problems, because it’s perfectly possible to have a financial crisis that mainly takes the form of a run on smaller institutions. In fact, that’s precisely what happened in the 1930s, when most of the banks that collapsed were relatively small — small enough that the Federal Reserve believed that it was O.K. to let them fail. As it turned out, the Fed was dead wrong: the wave of small-bank failures was a catastrophe for the wider economy.

The same would be true today. Breaking up big financial institutions wouldn’t prevent future crises, nor would it eliminate the need for bailouts when those crises happen. The next bailout wouldn’t be concentrated on a few big companies — but it would be a bailout all the same. I don’t have any love for financial giants, but I just don’t believe that breaking them up solves the key problem.

So what’s the alternative to breaking up big financial institutions? The answer, I’d argue, is to update and extend old-fashioned bank regulation.
