It is far too early to judge the effects of the Brexit vote. As the global outlook evolves, it will be important to assess the implications for the U.S. economy, and for the stance of policy appropriate to foster continued progress toward our objectives of maximum employment and price stability.
I am often asked why rates remain so low now that we are near full employment. A big part of the answer is that, at least for the time being, the appropriate level of rates is simply lower than it was before the crisis. As a result, policy is not as stimulative as it might appear to be. Estimates of the real interest rate needed to keep the economy on an even keel if it were operating at 2 percent inflation and full employment--the "neutral rate" of interest--are currently around zero. Today, the real short term interest rate is about negative 1-1/4 percent, so policy is actually only moderately stimulative. I anticipate that the neutral rate will move up over time, as some of the headwinds that have weighed on economic growth ease.
