USDA's Grain Transportation Report shows corn and soybean shipping costs from Minneapolis to Japan rose quarter over quarter in Q1 2026 on both the Gulf and Pacific Northwest routes. The Gulf increase partly reflects switching to rail data during the winter river closure.
Year over year, Gulf transport costs rose 7% for corn and 4% for soybeans.
Higher freight raises landed costs for Asian buyers and trims the farm-gate value US exporters can pass back, which weighs on US export competitiveness. The effect is most visible in basis and export spreads rather than futures.
