Abstract

We examine the correlation and volatility of Islamic indices and their conventional counterparts during the 2008–2009 Global Financial Crisis as well as the Covid-19 pandemic. We provide evidence that the volatility of Islamic indices is relatively lower than that of conventional peers during turmoil periods. Consistent with the decoupling hypothesis, our results indicate that the volatility of Islamic and the volatility of conventional indices tend to move in tandem in tranquil times but diverge in times of crises. Our results also indicate that the correlation between Islamic and conventional indices is a priced risk factor for Islamic index returns.
