USDA AMS reported that the cost of delivering U.S. corn, soybeans and wheat to Mexico rose on every tracked route from the second to third quarter of 2026. Water routes rose most, with Illinois corn and soybean transport to Veracruz up 18% to $82.68 per metric ton, driven by barge rates lifted by low Mississippi River water, higher ocean rates and diesel costs.
Higher logistics costs widen the basis gap for U.S. grain sold into Mexico, reducing export competitiveness versus other origins and weighing on Gulf and Mississippi barge-linked prices.
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 297 past bearish logistics events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.5% to +1.8%), and +0.7% 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.
