Abstract
Global supply chains are of strategic importance in today’s global economy. The disruption of grain supplies from Ukraine emphasises the vulnerability of these chains to unpredictable factors and justifies the relevance of the study of possible risks and consequences. The purpose of the study is to analyse the potential negative consequences that may arise due to disruptions in the supply of Ukrainian grain in the global supply chain. The research is theoretical and is based on the use of the following methods of cognition: case analysis, system and descriptive analysis, modelling, and simulation. The results indicate that disruptions in the supply of Ukrainian grain can have a serious impact on the global market and the economy of Ukraine in particular, which can lead to changes in grain prices, losses for Ukrainian agricultural enterprises, and impact on food security, both in Ukraine and in the world. This study can form the basis for building an effective strategy for minimising potential negative consequences and risks for the global market and economy of Ukraine, which is important for ensuring the sustainability and reliability of grain supply chains.
