This paper analyzes the impact of economic policy uncertainty on the term structure of real and nominal interest rates. We derive a general equilibrium model where the real side of the economy is driven by government policy uncertainty and the central bank sets money supply endogenously following a Taylor rule. We analyze the impact of government and monetary policy uncertainty on nominal yields, short rates, bond risk premia and the term structure of bond yield volatility. Furthermore, we show that our standard affine yield curve model is able to capture both, the shape of the term structure of interest rates as well as the hump-shaped bond yield volatility curve. Finally, the empirical analysis shows that, whereas higher government policy uncertainty leads to a decline in yields, and an increase in bond yield volatility, monetary policy uncertainty does not have a significant contemporaneous effect on movements in the yield or volatility but is however an important predictor for bond risk premia.
