U.S. barge freight rates have spiked as spot and April demand surge and empty barge supply tightens. St. Louis spot rates rose from 470% to 871% of the benchmark tariff ($34.75 per ton), and Upper Ohio River rates more than doubled.
Global buyers are reportedly substituting U.S. grain for Black Sea supplies cut off by the war.
Freight is a major component of delivered grain cost, so the barge spike widens the gap between Gulf export values and interior farm prices. Rising fuel costs add further pressure, supporting freight-linked costs for feed buyers.
