This study examines the impact of the Russia-Ukraine war on the top ten stock markets, along with Russian markets and oil markets. The event study methodology is employed to examine the abnormal returns, and later results' robustness is tested by non-parametric tests. The first finding is that European markets are worst hit by war. Second, US markets generated significant upside abnormal returns. Third, Asian markets are the least affected. Interestingly despite sanctions, Russian markets gave maximum positive cumulative abnormal returns for ten days post the event day. Further, oil markets acted as an effective hedge on expected lines. This study implies that the investors may consider the southern nations to diversify the war risk since most wars that happened in the past were in the Middle East or European region. The southern hemisphere has less proximity and dependency on the Middle East and Europe.
