Bulk ocean freight rates for U.S. grain from the Gulf and Pacific Northwest rose in the third quarter of 2025 versus the second quarter, with Gulf-to-Japan averaging $54.36 per mt, up 17%. Rates remained below year-ago levels and the four-year average.
Strong Chinese bulk imports and low Paraná River water levels in Argentina lifted demand and costs.
Higher freight widens the cost gap for U.S. grain exports against Black Sea and South American supply, which can weigh on U.S. export basis and farm-gate prices. Rates remain moderate, so the pressure is contained.
