Downbound corn barge shipments through Locks 27 near St. Louis reached 745,000 tons for the week ending June 16, the highest weekly volume since 2009. USDA data show total grain barge movements up 110% from a year earlier.
High water on the Upper Mississippi is expected to disrupt traffic, and Ohio River lock problems may halt traffic from around June 23.
Strong corn barge demand and river disruptions tighten barge capacity and lift freight costs, supporting Gulf and Midwest corn basis. Higher barge rates raise delivered corn costs for feed buyers.
After 285 past bullish logistics events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.5% to +1.5%), and +0.8% over 20.
