The U.S. Monetary Policy Forum has become an important venue for promoting an exchange of views among policymakers, academics, and financial market participants. I’m pleased to participate in this panel on lessons learned about unconventional monetary policy. In my remarks today, I’ll highlight the role of central bank communications in bolstering the effectiveness of unconventional monetary policy.1 It is not my intention to provide new information about the outlook for the U.S. economy or monetary policy.
The Federal Open Market Committee (FOMC) has deployed unconventional monetary policy tools to promote economic recovery and price stability since late 2008. In particular, after the intensification of the financial crisis, conventional monetary policy became constrained by the zero lower bound on nominal interest rates. At that point, the FOMC began to provide forward guidance about the likely path of the federal funds rate, and the Federal Reserve also announced a program to buy agency debt and mortgage-backed securities (MBS). Over time, the purchase program was augmented substantially and was expanded to include longer-term Treasury securities. Furthermore, on several occasions, the FOMC has communicated to the markets about the likely longer-term trajectory of its holdings of Treasury securities, agency debt, and agency MBS.
In the remainder of my remarks, I will present some evidence regarding the effectiveness of these policy tools and discuss important similarities and differences in the transmission mechanisms through which they influence the economy. I will also present some simulations of a macroeconometric model to illustrate the importance of clear and effective communication in conjunction with the use of these unconventional policy tools.
Some General Observations
It is important to recognize at the outset that conventional and unconventional monetary policy actions bear many similarities. Forward guidance concerning the path of the federal funds rate, for example, is explicitly intended to influence market expectations concerning the future trajectory of shorter-term interest rates and thereby affect longer-term interest rates. That said, standard monetary policy actions also typically alter not just current short-term rates, but the anticipated path of short-term rates as well, influencing longer-term rates through the identical channel. In fact, central bankers have long recognized that this “expectations channel” operates most effectively when the public understands how policymakers expect economic conditions and monetary policy to evolve over time, and how the central bank would respond to any changes in the outlook.
The transmission channels through which longer-term securities purchases and conventional monetary policy affect economic conditions are also quite similar, though not identical. In particular, central bank purchases of longer-term securities work through a portfolio balance channel to depress term premiums and longer-term interest rates. The theoretical rationale for the view that longer-term yields should be directly linked to the outstanding quantity of longer-term assets in the hands of the public dates back at least to the 1950s.2
Each of these policy tools tends to generate spillovers to other financial markets, such as boosting stock prices and putting moderate downward pressure on the foreign exchange value of the dollar. My reading of the evidence, which I will briefly review, is that both unconventional policy tools–the use of forward guidance and the purchases of longer-term securities–have proven effective in easing financial conditions and hence have helped mitigate the constraint associated with the zero lower bound on the federal funds rate.
The Effectiveness of Forward Guidance
I will begin with an assessment of the FOMC’s forward guidance concerning the federal funds rate, which began when the FOMC reduced its funds rate target to a range of 0 to 1/4 percentage point. In particular, the December 2008 FOMC meeting statement indicated that “economic conditions are likely to warrant exceptionally low levels of the federal funds rate for some time.” Identical guidance was reiterated in January 2009, and in March 2009 the phrase “for some time” was changed to “for an extended period.”
Figure 1 suggests that the provision of guidance concerning the future path of the federal funds rate likely contributed to more accommodative financial market conditions. In particular, the consensus outlook of professional forecasters regarding the path of the funds rate shifted down markedly in the Blue Chip survey published at the beginning of February 2009 (the solid line) compared with the survey published two months earlier (the dashed line).
