The term structure and inflation uncertainty

To assess the importance of inflation risk for nominal Treasury yields, a novel quadratic term structure model with time-varying inflation risk is estimated using survey-based inflation uncertainty. The resulting yield decomposition captures very diverse macroeconomic dynamics of inflation and real risk premiums (large and positive during the 1980s but small and negative post-2008) and generates sensible high-frequency estimates of expected inflation and real short rates over a long sample. The explicit link between the model-implied factors and macro fundamentals reveals that shortbut not long-run fluctuations are unspanned by yields, consistent with an interest rate policy unresponsive to transient inflation shocks.
