Wheat closed sharply higher in both Chicago and Kansas City markets on July 15, 2026, tied to rising Black Sea tensions with Russia reportedly unable to ship through the Sea of Azov and to a USDA report. The weekly export sales report showed corn net sales of 315.0 thousand tonnes and soybean sales of 188.3 thousand tonnes for the week ended July 9.
Black Sea shipping disruption tightens global wheat export availability, supporting wheat prices. Strong US corn and soybean export commitments support feed grain demand and prices.

Wheat closed sharply higher on July 15 on Sea of Azov shipping limits, which confirms the trade-flow driver, but the date is after the move.
