This paper attempts to identify economic and financial factors contributing to the changing correlations of recent stock returns. Time-varying correlations have been documented in previous studies, but few attempts have been made to investigate their evolution. Focusing on the Asia-Pacific region, this paper shows that daily return correlations tend to be higher in advanced countries, are negatively correlated with the distance between markets, and increase at times of active trading and financial turmoil. Furthermore, while some explanatory variables tend to lose their statistical significance during financial crises, volume data have strengthened their relationship with return correlations, particularly around the Lehman Shock.
