"Although the federal funds rate is now close to zero, the Federal Reserve retains a number of policy tools that can be deployed against the crisis. One important tool is policy communication. Even if the overnight rate is close to zero, the Committee should be able to influence longer-term interest rates by informing the public’s expectations about the future course of monetary policy. To illustrate, in its statement after its December meeting, the Committee expressed the view that economic conditions are likely to warrant an unusually low federal funds rate for some time. To the extent that such statements cause the public to lengthen the horizon over which they expect short-term rates to be held at very low levels, they will exert downward pressure on longer-term rates, stimulating aggregate demand. It is important, however, that statements of this sort be expressed in conditional fashion--that is, that they link policy expectations to the evolving economic outlook. If the public were to perceive a statement about future policy to be unconditional, then long-term rates might fail to respond in the desired fashion should the economic outlook change materially."
