DP17185 Proximity to War: The stock market response to the Russian invasion of Ukraine
The outbreak of a war exposes countries and firms in its proximity to the risk of military escalation. Disaster risk goes up and stock markets decline accordingly. In support of this hypothesis, we identify a "proximity penalty" in the stock market response to the Russian invasion of Ukraine. The closer countries and---even within countries---firms are located to Ukraine, the more negative their equity returns in a four-week window around the start of the war. Controlling for trade-related spillovers, 1,000 kilometers of extra distance equate to 1.1 percentage points in equity returns.
