George F. Will: The bankbuster

There is no convincing consensus about a correlation between a bank's size and supposed efficiencies of scale, and any efficiencies must be weighed against management inefficiencies associated with complexity and opacity. Thirty or so years ago, Brown says, seven of the world's 10 largest banks were Japanese, which was not an advantage sufficient to prevent Japan's descent into prolonged stagnation. And he says that when Standard Oil was broken up in 1911, the parts of it became, cumulatively, more valuable than the unified corporation had been.

Brown is fond of the maxim that “banking should be boring.” He suspects that within the organizational sprawl of the biggest banks, there is too much excitement. Clever people with the high spirits and adrenaline addictions of fighter pilots continue to develop exotic financial instruments and transactions unknown even in other parts of the sprawl. He is undecided about whether the proper metric for identifying a bank as “too big” should be if its assets are a certain percentage of GDP — he suggests 2 percent to 4 percent — or simply the size of its assets (Richard Fisher, president of the Federal Reserve Bank of Dallas, has suggested $100 billion).

By breaking up the biggest banks, conservatives will not be putting asunder what the free market has joined together. Government nurtured these behemoths by weaving an improvident safety net, and by practicing crony capitalism. Dismantling them would be a blow against government that has become too big not to fail. Aux barricades!
