Key Takeaways:
At risk: Up to 86 million tonnes of global cereal exports, about 17 percent of the total, per Oxford Economics.
Chicago wheat futures rose 17 percent since early July to near three-year highs as Black Sea attacks disrupt peak-season grain exports from Russia and Ukraine.
Ukraine's infrastructure ministry recorded 35 attacks on vessels in port, 22 at sea and 67 on port facilities during July alone, compared with 14 incidents in all of 2025, according to ministry data cited by Reuters.
Ukraine's grain exports fell about 76 percent year-on-year in August, with shipments of roughly 500,000 tonnes equal to about 20 percent of the country's potential export capacity, according to Bloomberg data. Russia's three major grain terminals at Novorossiysk have restricted truck deliveries because of maritime risks, Reuters reported in July.
Oxford Economics estimates disruption across both countries could remove as much as 86 million tonnes from global cereal exports this year, about 17 percent of the total. With August the peak month for shipping newly harvested grain, buyers from Egypt to Indonesia are already seeking alternative suppliers at higher costs.
Russia and Ukraine together account for about 30 percent of global wheat exports, according to Oxford Economics estimates, making the Black Sea one of the most critical corridors in international food trade. The two countries also supply significant volumes of barley, corn and sunflower oil.
Asian grain processors had booked an estimated 2 million to 2.5 million metric tons of Black Sea wheat for July-through-September arrival, representing 30 to 50 percent of regional import demand, according to traders cited by AgroLatam. Indonesia, the world's second-largest wheat buyer, contracted roughly 600,000 tons from former Soviet exporters for the period.
Egypt, the largest wheat importer globally, sourced more than 82 percent of its wheat imports from Russia and Ukraine during the first half of 2026. Jordan canceled wheat and barley tenders in August after receiving limited offers because of higher prices and shipping risks.
Alternative origins come at a premium. Australian Premium White wheat was quoted at $315 to $320 per metric ton delivered to Asia, compared with roughly $305 for the cheapest U.S. wheat and $260 to $280 for Black Sea cargoes, according to trader data.
The conflict-driven supply squeeze coincides with a deteriorating global crop outlook. The U.S. Department of Agriculture estimates combined wheat production across the top seven exporting countries will fall 11 percent for the 2026/27 marketing year, with exports down 7 percent.
U.S. wheat production is projected to drop 26 percent, with hard red winter output cut by an estimated 29 percent after persistent drought in the southern plains. Canadian production is expected to fall 15 percent, while Australia's wheat plantings are down 12 percent and Argentina's exports are forecast to decline 19 percent, according to USDA data.
Wheat prices have climbed almost 25 percent above January 2026 levels, according to IFPRI data, though they remain below the 2022 peak that followed Russia's initial invasion. JPMorgan analyst Nora Szentivanyi warned last week that the next global food crisis could arrive as early as next year if Black Sea shipping remains disrupted.
The longer attacks continue, the greater the risk that temporary shipping problems become a prolonged supply squeeze. Insurers and shipping companies may raise costs or refuse to operate in the region, pushing freight and insurance premiums higher even if global grain supplies remain adequate.
