The Mississippi River is unusually low for the third straight year, forcing barge companies to limit cargo loads. About 60% of U.S. grain exports move by barge down the river to New Orleans.
USDA data showed St. Louis-origin freight rates were up 57% versus the three-year average.
Cargo limits on barges cut the volume of grain reaching Gulf export terminals and push freight costs sharply higher. Elevated freight rates lower farm-gate bids for corn and soybeans from interior regions.
