USDA's AMS Grain Transportation Report shows total grain tonnage rose 2% from 2019 to 2020, with barge share up 2 points. It also reports that Mississippi River levels have fallen since June, driving barge spot rates at St. Louis to $23.34 a ton, up 49% week over week.
Tight barge supply from river restrictions raises freight costs for grain moving to export, which pressures interior basis and can shift export competitiveness.
