CBOT wheat settled up 5% on July 15 as Russia and Ukraine escalated attacks over the Black Sea and trade routes. Ukraine has lost about a third of its Black Sea export capacity, and Russia restricted Sea of Azov shipping that handles about a quarter of its grain exports.
France cut its 2026 soft wheat forecast 4% to 32.0 million tons after heat waves.
Losses in Ukrainian and Russian export capacity plus a smaller French crop tighten global wheat supply, supporting prices. Large fund short positions add upside volatility through short covering.
