The Economic Impact of Volatility Persistence on Energy Markets

Author

Abstract

This study examines the role of daily volatility persistence in determining future volatility in energy markets. In crude oil and natural gas markets, the impact of returns and variances is primarily transmitted to future volatility via the daily volatility persistence. Macro-economic factors, such as the VIX, the credit spread and the Baltic exchange dirty index, also impact future volatility, but this impact is again channeled via the volatility persistence. The dependence of volatility persistence on macro-economic conditions is termed conditional volatility persistence (CVP). The variation in daily CVP is economically significant, contributing up to 17% of future volatility and accounting for 25% of the model's explanatory power. Inclusion of the CVP in the model significantly improves volatility forecasts. Based on the utility benefits of volatility forecasts, the CVP adjusted volatility models provide up to 160 bps benefit to investors compared to the HAR models, even after accounting for transaction costs and varying trading speeds.
