Cleaning up Wall Street Oligarchy

Interesting ideas from the Atlantic on cleaning up the detritus of large banks looming over on Wall Street.

Cleaning up the megabanks will be complex. And it will be expensive for the taxpayer; according to the latest IMF numbers, the cleanup of the banking system would probably cost close to $1.5trillion (or 10percent of our GDP) in the long term. But only decisive government action—exposing the full extent of the financial rot and restoring some set of banks to publicly verifiable health—can cure the financial sector as a whole. This may seem like strong medicine. But in fact, while necessary, it is insufficient. The second problem the U.S. faces—the power of the oligarchy—is just as important as the immediate crisis of lending. And the advice from the IMF on this front would again be simple: break the oligarchy. Oversize institutions disproportionately influence public policy; the major banks we have today draw much of their power from being too big to fail. Nationalization and re-privatization would not change that; while the replacement of the bank executives who got us into this crisis would be just and sensible, ultimately, the swapping-out of one set of powerful managers for another would change only the names of the oligarchs.

Ideally, big banks should be sold in medium-size pieces, divided regionally or by type of business. Where this proves impractical—since we’ll want to sell the banks quickly—they could be sold whole, but with the requirement of being broken up within a short time. Banks that remain in private hands should also be subject to size limitations. This may seem like a crude and arbitrary step, but it is the best way to limit the power of individual institutions in a sector that is essential to the economy as a whole. Of course, some people will complain about the “efficiency costs” of a more fragmented banking system, and these costs are real. But so are the costs when a bank that is too big to fail—a financial weapon of mass self-destruction—explodes. Anything that is too big to fail is too big to exist.
