The Russia-Ukraine conflict reduced global wheat supplies, yet the food security implications vary across countries. We identify a 39% decrease in Ukrainian wheat exports in 2022 resulting in >70% import losses in some of the countries most vulnerable to these disruptions, with substantial impacts felt in Egypt, Oman, Saudi Arabia, Libya, Mauritania, Yemen, and Lebanon. Differential impacts are a function of access to capital and international trade, suggesting the need for policy measures to defuse the impending food crisis.
