USDA's Foreign Agricultural Service says Ukraine's grain exports in the first three months of 2026/27 averaged about half the pace of 2025/26 as attacks disrupted ports, railways, bridges and marine traffic. USDA projects record ending stocks of corn and wheat, and some corn may stay in fields through winter for lack of storage.
Reduced Ukrainian exports ease competition for buyers in the near term, but large carry-in stocks are a bearish risk for corn and wheat if shipping conditions improve.
After 359 past bearish logistics events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -1.5% to +1.5%), and -0.5% over 20.
After 137 past bearish logistics events, Wheat (SRW) moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.0%), and +0.0% over 20.
