The USDA cut Ukraine’s 2026/27 corn export forecast to 10.2 million tonnes from 22 million and lowered its wheat forecast to 8.7 million tonnes amid Black Sea security risks and attacks on logistics infrastructure. Despite slightly higher projected corn production, the agency expects record ending stocks, including 19.6 million tonnes of corn and 11.8 million tonnes of wheat; barley exports are forecast to rise slightly to 2 million tonnes.
Lower expected Ukrainian export flows tighten exportable supplies and could support global corn and wheat prices, while the large projected stock build signals surplus grain trapped by logistics and may cap local prices. Higher barley exports add some supply to that market.
After 1,040 past bullish report events, Corn moved a median +0.5% over 5 sessions (62% higher; middle half -0.9% to +2.0%), and +0.8% over 20.
