Volatility spillovers among the Gulf Arab emerging markets

This paper examines the volatility spillovers among Gulf Arab emerging markets. Multivariate VAR-GARCH model of daily returns, with BEKK specification based on the conditional variances and conditional correlations, is estimated for all six GCC equity markets of Saudi Arabia, Kuwait, UAE, Qatar, Oman, and Bahrain. The results show high own-volatility spillovers and a high degree of own-volatility persistence in all GCC markets. Moreover, there are significant cross-volatility spillovers and cross-volatitlity persistence among all GCC equity markets, with stronger evidence from all GCC markets to the Saudi market. Such evidence could be explained by the existence of uncertainties surrounding various Gulf bank exposures to certain Saudi business groups as well as the downward movement of oil prices.
