Abstract

This study, by taking NSE Nifty 50, DJIA, CAC, DAX, FTSE, Straits Times, Hang sang, Shanghai, Nikkei 225 and Kospi, as a reference, tries to understand and evaluate the impact of the Israel-Hamas war on these indices to demonstrate the comprehensive movements of the index prices. For elucidating the impact of the Israel-Iran war on major global index's returns the event study methodology has been used. This study analyses the change in the index prices which in turn reflects how the event affected market returns. The results underscore the differential impact of geopolitical conflicts on global stock markets. The Israel-Iran war had a significant and varied impact on global stock markets. While most indices showed declines, the magnitude and direction of the changes differed across regions, reflecting diverse market sensitivities to geopolitical events.
