Macro News and Long-Run Volatility Expectations

Abstract

I propose a new model-free method for estimating long-run changes in expected volatility using VIX futures contracts. The method is applied to measure the effect on stock market volatility of scheduled macroeconomic news announcements. I find that looking at long-run changes gives qualitatively different results compared to previous studies that only look at realized variance and the VIX. I further find that FOMC announcements on average resolve uncertainty, but only during times when policy uncertainty is higher than average. Real side macro announcements increase long-run volatility during times of low policy uncertainty, but the effect is reversed during times of high policy uncertainty.
