Abstract

Using an empirical model, this paper finds that shortening the average maturity of US Treasury debt held outside the Federal Reserve by one year reduces the five-year forward 10-year yield by between 130 and 150 basis points. Based on a pre-crisis period, these estimates suggest portfolio balance effects are unlikely to reflect only post-crisis market conditions. These findings also offer a partial explanation for the Greenspan conundrum: the fact that long-term interest rates in the mid-2000s rose less than expected after a rise in the Fed fund rate may have been due, to some extent, to the concomitant shortening of government debt maturity.
