Abstract: The present paper aims to study the diplomacy influence on the stock market by analysing the impact of Russia and Ukraine's warfare in the long run, short run, dynamic relationships and innovations between Brent crude oil, the Nifty 50 and the S%P 500. So, the study collects the daily closing prices. The entire study period has been split into two sections: before and during the war. The co-integration model is used to examine the long-term relationship. It found that there is no co-integration, also, there is no short-term relationship except for the S%P 500 to Nifty 50 in both periods. While checking the impulse response and variance decomposition, it was observed that before the war, there was a negative trend response in Brent to the S%P 500 and during the war, there was a negative trend response in Brent to the Nifty 50, the S%P 500 to Brent and the Nifty 50 to Brent.
