The impact of political conflicts and natural disasters on global economy has been shown in previous studies; however, evidence is lacking to show international impacts on global stock markets with statistical results. This study investigates the impact of political conflicts and natural disasters on international stock markets throughout the period for 2010 to 2014. Utilizing event study methodology, specifically the market model, the findings reveal that the impact of the catastrophic events on six international countries, such as U.S, Japan, China, Hong Kong, South Korea and Taiwan have significant influenced international stock markets. The results indicated that individual countries are more influenced by political conflicts than natural disasters and the more individual countries are related to international political interest, the more they are affected by the events. The findings say that the developed stock markets such as United States and Japan recover faster than emerging markets such as Shanghai, South Korea and Taiwan. It is because the developed markets have much transparent and well organized financial systems. Finally, the results indicate that several positive and negative co-movements are observed because of globalization and open market economy system.
