The event study methodology has been used to empirically test the stock market efficiency upon the announcement of the Red Sea Crises on the S&P GSCI Commodity index. The study takes the pre-event period of 15 days and the post-event period of 15 days. For S&P GSCI Commodity index, AAR and CAAR were calculated to determine the impact of the Red Sea Crisis. The null hypothesis stated that there is no significant difference between the Average Abnormal Returns before and after the date of the announcement of the Red Sea Crises on the S&P GSCI Commodity Index. The paired samples t-test was carried out and the null hypothesis is accepted at the 5% significance level, suggesting that the event did not have any statistically significant impact on the S&P GSCI Commodity index.
