Uncertainty and Dispersion in Professional Interest Rate Forecasts: International Evidence and Theory

Abstract

We examine the cross-country relationships between measures of forecast uncertainty, forecast dispersion across individual forecasters and the variabilities of short-term interest rates and long-term yields. The main findings are: (i) Forecast uncertainty and forecast dispersion are positively and significantly related across countries for both short-term interest rates and long-term yields. (ii) A positive, albeit weaker, relation is found between forecast uncertainty and interest rate variability. (iii) Forecast dispersion of short-term interest rates and rates' variability are also positively associated. The evidence is followed by a Bayesian learning model that discusses conditions under which the results above are implied by theory.
