Black Sea Blockade Threatens Global Grain Supply and Russian Wheat Planting

Intensified attacks on ports, grain terminals, elevators and vessels in the Black Sea have sharply reduced shipments from Russia and Ukraine. The blockade, which began in July, has cut the flow of wheat, sunflower oil and corn that together account for more than a quarter of global wheat trade, about two-thirds of sunflower-oil trade and roughly 10 % of world corn supplies. The disruption forces the largest importers to seek alternative sources and pushes wheat prices to three-year highs.

Russia and Ukraine together supply more than 25 % of the world’s wheat. Prior to the escalation, the Odesa region handled about 90 % of Ukraine’s grain exports. Since the attacks, Ukraine’s agricultural exports fell to their lowest level since April 2022, and grain storage facilities risk filling by early November. Turkey has offered a new grain-corridor plan, while the EU warned that further Black Sea disruptions could trigger a new global food-security shock, especially for African and Middle-East nations that rely heavily on Ukrainian and Russian grain.

The winter planting window runs from September to November. Russian authorities plan to continue subsidizing rail logistics and may expand state grain purchases if export bottlenecks persist. Without sufficient storage, many growers are expected to reduce wheat acreage further and pivot to alternative crops, potentially tightening global wheat supplies into the 2027 harvest season.
