Williams, John

I expect that the explicit link between future policy actions and specific numerical thresholds, as in the recent FOMC statements, will not be a regular aspect of forward guidance, at least when the federal funds rate is not constrained by the zero lower bound. This guidance has proven to be a powerful tool in current circumstances, when conventional policy stimulus has been limited by the zero lower bound. But such communication is difficult to get right and comes with the risk of oversimplifying and confusing rather than adding clarity. Therefore, in normal times, a more nuanced approach to policy communication will likely be warranted. I see forward guidance typically being of a more qualitative nature, highlighting the key economic factors that affect future policy actions. Of course, if we again find ourselves in a situation where conventional policy has been fully utilized, then we will have the ability to return to more explicit forward policy guidance to provide additional monetary stimulus.

We should, however, only resort to asset purchases as a policy tool in special circumstances, such as when the federal funds rate is near zero and we have fully utilized forward policy guidance. Despite all that we’ve learned, the effects of asset purchases are much less well understood and are much more uncertain and harder to predict than for conventional monetary policy. Indeed, the recent outsize movements in bond rates in response to Fed communications about our current asset purchase program illustrate the difficulty in gauging the effects of asset purchases. Moreover, given our limited experience, we can’t be sure of all their consequences, which may play out over many years. When the federal funds rate was at zero and we were still facing a severe recession, it was the right call to turn to asset purchases. But, once the federal funds rate is back to a more normal level, we should relegate asset purchases to a backup role, employing it only when conventional policy and forward guidance fall short.
