Chicago corn futures rose on Friday, supported by technical buying and US export demand. Exporters sold 303,300 tonnes of US corn to Mexico, and weekly export sales for 2026/27 reached 2.9 million tonnes, at the top of analyst expectations.
December corn closed up 3 cents at $4.455 a bushel, while soybeans gained about 1% to $12.315.
Strong export sales to Mexico and a USDA cut to US production and stocks tighten the US corn balance, supporting prices. Firm soybean and wheat moves alongside suggest the rally is broad-based across grains.
After 737 past bullish trade events, Corn moved a median +0.4% over 5 sessions (57% higher; middle half -1.1% to +1.7%), and +0.5% over 20.
