A Month of Black Sea Disruption: How Port Attacks Are Reshaping Global Wheat and Edible Oil Trade

From Azov to the World: A Month of Export Paralysis

A month of sustained strikes against port infrastructure and commercial vessels in the Azov and Black Sea regions has severely disrupted the grain and sunflower oil export arteries of Russia and Ukraine—together accounting for nearly 30% of global wheat and over 60% of sunflower oil exports. The immediate result: shipments from Russia’s Azov ports have halted entirely, while its main Black Sea terminal at Novorossiysk is overwhelmed. In the third week of July 2026, Russian wheat loadings were down 18% year‑on‑year, with flows from the Azov-Black Sea basin collapsing by 55%.

The consequences are cascading through global food markets. If the attacks persist, Russia’s wheat exports could drop by 30–35 million tonnes—a 15% reduction in world wheat trade—according to the Russian Union of Grain Exporters and Producers. Ukraine’s deep‑sea ports in Greater Odesa and Mykolaiv are paralysed, and its agriculture minister has warned that by November storage capacity will be insufficient, leaving more than 27 million tonnes of agricultural products unshipped this year.

Already, benchmark wheat prices have jumped almost 13% in Europe and 14% in the United States, while Russian wheat prices have remained relatively stable, up only 2%. Sunflower oil prices in India—a major buyer from the Black Sea region—rose 6% in July as importers scrambled for alternatives. Meanwhile, a parallel shipping crisis in the Bab el‑Mandeb strait and a severe drought in the EU, Canada and the United States are compounding the turmoil, raising the spectre of prolonged food inflation and supply gaps for the most vulnerable importers.

Behind the Blockades: Fragile Supply Chains and Escalating Risks

Russia’s Grain Sector Faces an Export Bottleneck

With 85% of its grain normally shipped by sea and 80% of that via Azov-Black Sea terminals, Russia cannot quickly replace the lost capacity. Baltic ports such as Vysotsk and Ust‑Luga will be used to redirect southern grain, but limited rail capacity, high overland freight costs and congestion cap how much can flow northward. Kaliningrad offers even less relief—only 0.5 million tonnes were shipped through it in 2025, mostly locally produced grain—while transit restrictions through Lithuania block any large‑scale re‑routing from central and southern Russia. The Russian Union warns that the full‑year export loss of 30–35 million tonnes would not only shrink Moscow’s market share but also cut producer revenues just as farmers need cash for the next sowing campaign.

Ukraine’s Agriculture on the Brink Without Sea Lanes

Ukraine faces an even darker picture. Over 90% of its agricultural exports rely on seaborne routes now closed, and alternative multimodal corridors via the Danube (which suffers frequent summer shallows), rail links through Hungary, Slovakia and Poland, or trucking to Baltic and Adriatic ports are both expensive and volumetrically tiny. The Ukrainian Agrarian Council estimates the country will need $20 billion in international financial support merely to stop the sector from collapsing; without it, farmers will be forced to sell at or below cost, storage overflow will spoil harvests, and the loss of traditional markets could become permanent.

The Global Food Importers Caught in the Crossfire

Dozens of nations depend on Black Sea supplies. Russia alone provides 25–70% of the grain imports of Egypt, Turkey, Iran and China, and more than 55% of their sunflower oil. India’s 6% price spike in domestic sunflower oil reflects how quickly supply shocks translate into consumer pain. Importers are now trying to switch to American, Canadian or Australian wheat, but those exporters are themselves hobbled by drought—EU wheat exports are forecast down 3%, Canada’s down 7% and US exports almost 13% lower. The scramble for alternative origins will inevitably push global grain prices higher and strain the foreign exchange reserves of food‑importing developing countries.

Logistics Chokepoints Multiply the Crisis

The Black Sea blockade is not happening in isolation. Through the Bab el‑Mandeb strait passes some 15% of the world’s wheat, almost 20% of global rice trade and 15% of all seaborne fertilizers. Houthi attacks have already cut shipping intensity by 56%, forcing vessels onto longer routes around Africa and adding roughly 20% to freight costs. This directly endangers food aid deliveries to East Africa’s hunger hotspots—Yemen, Sudan, South Sudan—and disrupts fertilizer supply to Asian farmers. A renewed surge in Somali pirate activity, with four small vessels seized since April, further darkens the outlook. Combined, the two chokepoints are threatening to reverse the 2022–2025 trend of slowly improving global food security, which had cut the number of undernourished people by 7%.

What Importers, Traders and Governments Must Do Next

• For food‑importing governments (Egypt, Iran, Turkey, Bangladesh, Nigeria, etc.): Immediately launch competitive tenders for non‑Black Sea wheat from the Americas, Australia and the EU, even at a premium, to build buffer stocks before further price spikes. Negotiate bilateral supply agreements with Indian and Central European producers that have surplus this year.
• For international donors and the FAO: Mobilise the $20 billion aid package identified by Ukraine’s agrarian council without delay to prevent a collapse of the country’s farm sector and to maintain its future export capacity. Ring‑fence funds for urgent storage and inland logistics upgrades.
• For Russian grain exporters and logistics operators: Secure dedicated rail capacity and terminal slots at Vysotsk and Ust‑Luga now, and press for diplomatic resolutions on Lithuanian transit corridors for Kaliningrad; each week of inaction means millions of tonnes of lost shipments that will be captured by competitors.
• For global commodity traders and shipping lines: Reroute available tonnage away from the Black Sea war‑risk zone and factor in at least a 20% rise in freight rates when pricing contracts for India‑Middle East‑Africa routes via the Cape of Good Hope.
• For agricultural ministries in drought‑hit exporting countries (EU, Canada, US): Prepare temporary export licensing or stock‑release mechanisms to prevent domestic bread price shock while still capitalising on the international supply gap—but be aware that protectionist measures could exacerbate global shortages.
• For the FAO and G20: Convene an emergency food security session to coordinate global grain reserve releases and to establish safe maritime corridors for fertiliser and humanitarian grain shipments through the Bab el‑Mandeb, as current disruption will deepen hunger in Afghanistan, Yemen, South Sudan and the Horn of Africa.
