Volatility spillovers and macroeconomic announcements evidence from crude oil markets

The paper employs an event study methodology to investigate the macroeconomic announcements effects on S&P500 and oil prices. Our results provide evidence of a significant impact of the US macroeconomic news on oil prices. This impact is split into two components, namely the direct effect (common response) and indirect effect (volatility transmission). Altogether our results show that the volatility transmission is bidirectional since a significant volatility transmission from the oil market to the US stock market is revealed. Furthermore, a higher volatility transmission is recorded from the oil market to the stock market especially after the release of consumption indicators.
