On the impacts of oil price fluctuations on European equity markets: Volatility spillover and hedging effectiveness

The objective of this paper is to investigate the volatility spillovers between oil and stock markets in Europe. As not all industries are expected to be equally affected by oil price changes, we conduct our study at both the aggregate as well as sector levels. Empirically, we make use of a recently developed VAR-GARCH approach which allows for transmissions in volatilities. In addition, we analyze the optimal weights and hedge ratios for oil-stock portfolio holdings based on our results. On the whole, our findings show significant volatility spillovers between oil price and sector stock returns, and suggest that a better understanding of those links is crucial for portfolio management in the presence of oil price risk.

► Volatility spillover effects between oil and sector stock markets in Europe are investigated. ► Empirical results from VAR-GARCH models help building oil-stock portfolio designs and hedging strategies. ► There is evidence of significant cross-market volatility transmission. ► Spillover effects are more apparent from oil to stock markets, and come entirely from transmission of shocks. ► Average optimal weights and hedging effectiveness differ considerably across sectors.
