USDA AMS data show total grain barge movements on the Mississippi River System rose 11% in 2025 to the highest level since 2022, despite low water, ice and lock closures. First-quarter St. Louis spot rates reached $16.92 per ton, up 37% year over year, and third-quarter spot rates averaged $19.21 per ton.
Higher barge freight costs widen the gap between interior and Gulf export prices, lowering farm-gate bids and raising delivered costs for feed buyers. Strong corn volumes keep barge demand firm.
