Downbound barge grain shipments totaled about 2.07 million short tons in the week ending October 31, 2026, according to USDA AgTransport data. Soybeans made up about 1.54 million short tons, corn about 515,350 short tons and other grains about 12,550 short tons, with no wheat moved.

Soybeans dominate the weekly Mississippi volume, showing strong river movement to Gulf export positions. The data reflects flow rather than a new price driver, so the market impact is limited.
After 563 past neutral report events, Soybeans moved a median -0.1% over 5 sessions (48% higher; middle half -1.7% to +1.6%), and -0.1% over 20.
After 770 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
