Ben Bernanke has been busy recently—too busy, in the minds of some. The chairman has expanded the Federal Reserve's role beyond traditional monetary policymaker to being an all-purpose protector of the financial system.

The White House has proposed making the change official, adding financial stability to the Fed’s mandate. But it would need more power, and governors, to execute that function, and also risks losing its cherished political independence.
