The Impact Of The Persian Gulf Crisis On National Equity Markets

This paper uses the mean-adjusted returns and the market and risk-adjusted returns event-study methodologies to analyze the response of national equity markets to the Persian Gulf Crisis. Daily cumulative abnormal returns are computed for 16 national stock markets and three portfolios of national markets. The main empirical findings are: (1) the Persian Gulf Crisis had a negative effect on equity prices; (2) the Oil Crisis had a greater negative effect on the European, Asian, and Australian markets than on the American and Canadian markets; (3) the initiation of the Gulf War had a much lesser impact in the equity market prices than the invasion of Kuwait; (4) the national markets reacted to both events, the invasion of Kuwait and the start of the Gulf War with lags of two to three days. The negative abnormal returns following the invasion of Kuwait seem to reflect investors' fear of a long armed conflict in the Middle East. On the other hand, the positive abnormal returns following the initiation of the War suggest that investors expected a quick end to the Gulf War. Our results confirm the important role played by oil prices in the world economies and the limitations of international diversification. The efficiency of equity markets is also reflected in the fact that several national markets responded to the Persian Gulf Crisis according to the country's dependence on oil imports.
