Combined Russian and Ukrainian grain and oilseed shipments from Black Sea ports fell 63% year over year between July and September 2026, according to Kpler. Exporters have shifted toward Baltic ports, European rail networks and Danube terminals, but those routes have not replaced the lost capacity and face infrastructure and vessel constraints.
Reduced Black Sea shipments can redirect import demand toward competing origins, creating export opportunities for U.S. wheat and corn. Alternative routes remain constrained, keeping shipment costs and delivery uncertainty elevated.
