Abstract

We examine the effect of uncertainty arising from policy-shock volatility on yield-curve dynamics. In contrast to the assumption of many macro-finance models, policy-shock processes appear to be time varying and persistent. We allow for this heteroskedasticity by constructing a no-arbitrage GARCH affine term structure model, in which policy-shock volatility is defined as the conditional volatility of the error term in a Taylor rule. We find that an increase in monetary policy uncertainty raises the medium- and longer-term spreads in a model that incorporates macroeconomic dynamics.
