Could Black Sea attacks reopen the world’s grain wound?

Black Sea attacks are squeezing grain exports: Nearly two months of sustained Russian and Ukrainian attacks on each other’s commercial vessels, ports, and grain terminals have disrupted exports from both countries — pushing wheat futures to their highest level in three years, Bloomberg reports.

Ukraine’s grain exports reportedly fell to just a fifth of their potential volume in August, as repeated Russian strikes hit major Black Sea ports including Odesa, while attacks and capacity constraints also disrupted alternative routes via the Danube. The country may ship around 29.6 mn tonnes of agricultural products in the 2026/27 marketing year, down 54% from an earlier estimate of 64.4 mn tonnes, while wheat exports alone could fall 53% to 8.3 mn tonnes.

Russian wheat exports in September are expected to fall to their lowest level since 2010, according to research firm SovEcon, which expects shipments of 1.8-2.3 mn tonnes this month, compared with 4.8 mn tonnes a year earlier. Strikes have also damaged facilities at Novorossiysk — Russia’s main grain-export hub — and disrupted navigation through the Don-Azov Channel.

The bottleneck is the route to market

The grain is there, the routes are not: Both countries still have grain to sell, but damaged terminals, vessel risk, and constrained alternative routes are preventing it from reaching buyers. That has created a split market: wheat prices are falling inside Russia and Ukraine as grain accumulates, even as international futures rise and importers pay more to secure replacement cargoes.

Why this matters: Russia and Ukraine together supply more than a quarter of globally traded wheat, while also exporting major volumes of corn, barley, and sunflower oil. Russia alone accounts for roughly one in every six tons of wheat traded globally. Black Sea grain is typically among the cheapest available, making it important for price-sensitive importers across the Middle East, Africa, and Asia.

Who could benefit: Exporters in the EU, Australia, Argentina, and the US could capture displaced demand, with Romania and Bulgaria offering the closest alternatives. But replacement is not one-for-one; other origins may cost more, travel farther, or supply wheat with different milling qualities.

Can the backup carry the load?

Diversion options remain limited: Russia is redirecting grain toward its Baltic ports, but their estimated 7 mtpa capacity is a fraction of the 46.3 mn tonnes handled through the Black Sea and Sea of Azov last season — equivalent to some 90% of the country’s grain exports. Ukraine’s Danube fallback is also congested, with around 80 vessels waiting to enter its river ports at the end of August.

The risks are mounting, but the market is not yet in crisis. Global grain stocks remain relatively comfortable following strong harvests in previous years, while food commodity prices remain well below the records reached after the Russian-Ukrainian conflict started. Those buffers mean the immediate impact is more likely to appear through higher landed costs, freight rates, and government subsidy bills than widespread physical shortages.

The impact will vary by importer: Egypt and Jordan face the most immediate procurement and subsidy pressure, while Gulf states have greater purchasing power to pay for alternative supplies and a wide supplier options, allowing them to compete for alternative cargoes — potentially pushing more vulnerable importers further down the queue.

Two chokepoints, one shock

The Middle East is being squeezed between two disrupted trade corridors. Black Sea attacks are making the region’s cheapest grain harder and more expensive to secure, while the Hormuz disruptions are raising the cost of fertilizer, fuel, and freight. The impact is primarily a fiscal shock for now, not an immediate shortage.

The chokepoint problem is rippling across the whole system: The disruptions in Black Sea and Hormuz, alongside heat waves damaging European crops, are leaving the food system exposed at the input, production, and export stages. Grain trapped inside Russia is pushing down domestic prices and squeezing farm margins, which could prompt farmers to reduce winter planting. That would turn today’s export-logistics problem into an actual global supply constraint next season.

What to watch: Turkey is in talks with Russia and Ukraine about restoring safe passage for grain shipments through the Black Sea, potentially reviving a UN-brokered agreement — the Black Sea Grain Initiative — that got 33 mn tonnes of grain out of Ukraine during the early days of the conflict
