USDA/FAS forecasts Ukrainian ending stocks of major grains could reach a record 36.1 million tonnes in 2026/27, driven by severe export restrictions from Black Sea shipping risks. Corn exports are seen falling about 54% to 10.2 million tonnes and wheat exports about 38% to 8.7 million tonnes, while production rises to the highest since 2021/22.
Large Ukrainian stocks trapped by shipping disruption weaken export demand for Ukrainian corn and wheat, a bearish factor for world prices offset by reduced Black Sea supply availability. Export losses shift demand toward other origins.
After 770 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
After 406 past neutral report events, Wheat (SRW) moved a median -0.2% over 5 sessions (47% higher; middle half -1.6% to +1.5%), and +0.0% over 20.
