Since September 2023, 168.9 million tonnes of cargo have moved through the Ukrainian sea corridor, including 100 million tonnes of grain. Ukraine says Russia has significantly increased attacks on ships and ports, with December 2 2025 to January 12 2026 accounting for 10% of all infrastructure destruction since 2022.
Escalating attacks on Ukrainian ports raise insurance and logistics risk for Black Sea grain shipments, supporting freight rates and corn and wheat prices.
