Political tension and stock markets in the Arabian Peninsula

This note investigates the effects of the recent political tensions in the Arabian peninsula on the linkages between the stock markets of the leading Gulf Cooperation Council countries by estimating a VAR-GARCH(1,1) model at a weekly frequency. The results indicate that the June 2017 crisis lowered stock market returns and generally led to greater volatility spillovers within the region. This evidence supports the need for further financial integration and suggests fewer portfolio diversification opportunities for investors in the Gulf Cooperation Council region.
