One can view the proximity of the current Fed policy stance to the zero-lower-bound as an accident of history, or a wise choice. So, too, the grand scale and scope of the Fed’s balance sheet. No matter one’s judgment, the Fed finds itself with less conventional and unconventional ammunition. With ammunition low, Fed credibility – to act independently, get policy right, and explain well the rationale for its actions—is at a premium. Fed cred will be relied upon most when the economy slows or confronts a shock. So it’s encouraging that Fed is open to considering reforms in the conduct of monetary policy.
