Wheat Prices Hit Monthly High Amid Black Sea Supply Disruptions

Growing attacks by Russia and Ukraine on each other's export infrastructure in the Black Sea region have intensified market concerns over global food supply security, driving up grain futures prices. Chicago wheat futures rose again on Monday (10th), lifting corn and soybean prices along with it.

The Black Sea serves as the primary export gateway for Russia and Ukraine, two major agricultural powers. As both sides intensify strikes on grain infrastructure and vessels, market doubts over shipping reliability have translated into upward price momentum.

The most actively traded wheat contract on the Chicago Board of Trade (CBOT) surged up to 2.5% on Monday, hitting its highest level since July 30. This marks the fourth consecutive trading day of gains for wheat prices, the longest rising streak in nearly two months.

Hard Red Winter wheat saw particularly strong gains, rising 2.7% to $7.5050 per bushel. As this variety directly competes with high-protein milling wheat from the Black Sea and Europe, export disruptions have forced global importers to seek more diversified supply sources, further boosting the value of high-quality wheat.

Ukrainian President Volodymyr Zelenskiy accused Moscow of targeting global food security by attacking ports. Ukrainian officials warned that due to ongoing attacks, agricultural exports in the 2026-27 season could fall by more than half compared to earlier forecasts. Turkey also temporarily suspended its vessel transit due to increased safety risks in Black Sea shipping routes.

JPMorgan noted that slower loading speeds and rising insurance costs have effectively created a 'risk premium' in the market. Additionally, Ukraine's strikes on Russian fuel supplies could restrict diesel availability for agricultural machinery, potentially affecting Russia's agricultural output.

Beyond geopolitics, drought conditions are threatening other production regions. France, hit by heatwaves and drought, is expected to see its corn production drop 35% to 9 million tons this year compared to 2025, the lowest since 1980. Meanwhile, the U.S. dollar fell to its lowest level in nearly two months, enhancing the export competitiveness of American agricultural products.

Analysts indicate that with production below last year's levels in several major exporting countries, wheat prices are expected to remain above $6 per bushel in the short term and may trend toward $6.50.

Traders are now closely watching the upcoming monthly forecast report from the U.S. Department of Agriculture (USDA) for the latest data on production and planted acreage.
