Black Sea Tensions Disrupt Global Wheat Supplies, Threaten African Markets

Renewed tensions in the Black Sea have created fresh uncertainty for the global wheat market, disrupting shipments from Russia and Ukraine. The two countries account for about 27.3% of global wheat exports, making any prolonged interruption a major concern for import-dependent countries, particularly across Africa and the Middle East.

The International Food Policy Research Institute (IFPRI) reported that global wheat prices had risen almost 25% above January 2026 levels by early August, reaching their highest level in two years. The increase has been driven by a combination of Black Sea shipping disruptions, drought and declining production prospects among several major exporters.

Russia and Ukraine's export infrastructure have been affected by the latest escalation. Russian strikes on ports around Odesa have disrupted Ukraine's grain shipments, while Ukrainian attacks on Russian vessels and infrastructure have affected routes through the Sea of Azov and Black Sea.
