Wheat futures have maintained their gains after a 5% jump, following intensified Ukrainian and Russian attacks in the Black Sea region. This escalation threatens a vital export route for both warring countries. Chicago's most-active futures experienced slight fluctuations on Thursday, having previously surged to nearly a two-month high after the recent developments.

Ukrainian forces have reportedly struck multiple Russian vessels in the Black Sea, building on recent attacks against over 100 Russia-linked ships in the Sea of Azov. Concurrently, Russia has intensified its own attacks on Ukrainian ports, including Chornomorsk, Odesa, and Pivdennyi. The Black Sea is crucial for trade for both nations, with Russia being the world's largest wheat exporter.

This situation is reminiscent of the Black Sea supply shock in 2022 at the war's outset, which led to the closure of Ukrainian ports and left millions of tons of grain stranded. However, Rabobank senior grains and oilseeds analyst Vitor Pistoia suggests the current market reaction might be more contained this time around. He notes that while both events occurred during periods of tight global supply, the timing differs significantly. In 2022, the escalation happened before the Northern Hemisphere's spring planting and growing season, leading the market to price in risks of both lower production and export disruptions. In 2026, the focus is predominantly on export disruptions.

According to the Ukrainian Agrarian Council, Ukraine has already lost approximately a third of its grain export capacity via Black Sea ports due to ongoing Russian strikes. The Hightower Report commented that both Russia and Ukraine appear focused on hindering each other's export revenue, which is a bullish factor for wheat prices. European wheat prices also saw a 7% jump on Wednesday, with benchmark September milling wheat on Paris-based Euronext closing at €231.75 ($265) per tonne, a price not seen since February 2025. Analysts have also cut Russia's July wheat export forecasts by 13-20%, with IKAR now expecting exports below 2 million tonnes and SovEcon reducing its forecast to 2 million tonnes, representing a 4.8% year-over-year decline. Shipping restrictions in the Sea of Azov, handling about a quarter of Russia's grain exports, also pose a risk.
