USDA's Grain Transportation Report put Q3 2026 rail costs from Iowa to the US-Mexico border at $65.40 per tonne for corn, up 2.6%, while Missouri soybean rail fell 3% to $44.39. Kansas wheat rail rose 1.7% to $44.96.
Higher corn freight to the border trims the net price Iowa shippers can offer and can shift Mexican buying toward other origins, while cheaper soybean rail slightly supports soybean competitiveness into Mexico.
After 363 past bearish logistics events, Corn moved a median -0.3% over 5 sessions (45% higher; middle half -1.5% to +1.5%), and -0.5% over 20.
