Abstract

This paper examines the relationship between monetary policy uncertainty and the term structure of interest rates. Extending the Ellingsen and Söderström (2001) model, we demonstrate that long-term interest rates are positively related to monetary policy uncertainty, with the magnitude increasing with maturity. Further, we present empirical evidence to show that the theoretical prediction is generally consistent with US data.

Keywords:
Monetary policy, term structure of interest rates, GARCH.
