Englander: Is The Fed (Or Any Central Bank) Still Credible?
The Chicago Fed’s recent "Conference on Monetary Policy Strategy,Tools,and Communications Practices" was designed to address various questions (and doubts) that academics and economists have raised, and also to listen to those supposed practitioners' perspectives.
However, as Standard Chartered's Steve Englander details in the note below, the conference will have very little impact on market expectations and do little to allay investor concerns about the ineffectiveness of monetary policy near the zero bound.
Critically, Englander says, the problems that the papers at this conference address are not the problems that worry market participants.
Instead, the questions they should have asked are more straightforward to put forth - and more difficult to answer honestly for The Fed.
Are the Fed’s models broad enough?
The basic model includes a Phillip’s curve, a zero lower bound and a policy rule. It is meant to optimise policy outcomes over a long period of time using alternative rules and choose the one with the best set of outcomes based on some objective function. This is a simplified version of something that requires considerable technical expertise.
In this modelling framework, nothing can go wrong. Some policy rules work better than others, but all eventually meet the targets. There is no banking sector that stops lending when rates are super-low, no investors who go too far out the risk-return curve, and no financial markets that stop trading because the safest assets are concentrated in the Fed’s balance sheet.
Such features are very difficult to model analytically. They require parametrisation that reflects empirical regularities, which are very hard to come by. However, investor concerns are not whether price-level targeting beats inflation averaging, but whether either will solve the problem of the zero lower bound.
Is the Fed or any central bank credible enough?
To his credit, Fed Chair Powell has admitted: “In models, great confidence in central bankers is achieved by assumption.”
The credibility assumption requires the model to be correct and for investors to have confidence that the central bank can stick to it.
If the model is not correct, investors must choose between believing that the central bank will follow a doomed policy or that it will change its policy.
