Black Sea Escalation and Climate Events Raise Deep Concerns for Global Food Security

Grain exports from Russia and Ukraine have seen a sharp decline over the past two months, a direct consequence of ongoing attacks by both sides on commercial vessels and ports in the Black Sea and the Sea of Azov. This downturn has pushed wheat futures to their highest level in three years, raising global concerns about food supplies. Together, Russia and Ukraine account for over a quarter of global wheat exports, in addition to being major producers of barley, corn, and sunflower oil. The current disruptions are reminiscent of events in 2022, when the full-scale war in Ukraine effectively suspended cargo loading operations in Ukrainian ports, driving grain prices to record highs. While the current disturbances have not yet had the same impact on prices, they occur during a critical period for the global food sector. Compounding this, the disruption of navigation through the Strait of Hormuz due to regional conflict threatens the flow of fertilizers and other essential agricultural inputs. Concurrently, heatwaves have caused crop wilting in Europe, while the "El Niño" climate phenomenon threatens to inflict further damage on agricultural crop productivity on a broader scale. **Black Sea Escalation: Targeting Grain Infrastructure** For months, Russia has targeted Ukrainian grain export infrastructure with airstrikes, hitting facilities operated by some of the world's largest crop trading companies, including Bunge Global and Archer-Daniels-Midland. In July, Russia intensified its campaign, targeting cargo ships and key grain loading terminals in Chornomorsk, Odesa, and Pivdennyi. Since this escalation, Russia has been targeting Ukrainian ports on the Black Sea almost daily. Strikes have also hit Ukraine's ports on the Danube River, which has become a vital alternative hub for grain exports after Black Sea routes were disrupted. However, shipments via the Danube were already facing challenges due to low water levels caused by summer heat. **War and Weather Volatility Drive Up Crop Prices** These developments have led to a significant decline in Ukraine's grain exports. In August, exports dropped to an estimated one-fifth of their potential volume, according to Agriculture Minister Taras Vysotskyi. His ministry warned that the country's agricultural shipments for the current season might fall to less than half of the previously estimated quantity. Conversely, the situation does not appear much better for Russia. Ukrainian attacks on Russian ports and ships in the Black Sea and Sea of Azov have nearly crippled the maritime route that typically handles over 70% of Russian grain exports. In July, Ukraine struck two major Russian ports on the Sea of Azov coast, restricting transit through the Don-Azov Canal, which connects the sea to the Don River—a key waterway in Russia. In August, several grain terminals at the country's main export hub in Novorossiysk halted operations after suffering damage from a massive drone attack, with repairs expected to take several months. Russia has the option to use its Baltic Sea ports for exports, yet their limited capacity is insufficient to handle the substantial volume of approximately 60 million metric tons of grain that the country can export in a single season. As a result, Russia exported less than half the quantity of wheat in August compared to the same month last year. Research firm SovEcon predicted that September exports would fall to their lowest level for that month since 2010. **Global Significance of the Black Sea Region** The reason the 2022 conflict in Ukraine caused the largest recorded jump in global food prices is that the Black Sea is one of the world's most critical agricultural export corridors, through which a significant portion of wheat, corn, and sunflower oil trade passes. Ukrainian ports are vital gateways for exports to countries in Africa, the Middle East, and Asia, regions that cannot easily afford higher-priced grains from elsewhere. As the world's largest wheat exporter, Russia supplies roughly one in every six tons traded globally, making uninterrupted access to the Black Sea corridor crucial for global food markets. Matt Darragh, a grains and oilseeds analyst at Kpler, stated, "Black Sea wheat is typically the cheapest globally." He added that "price-sensitive buyers will either reduce import demand or face higher prices. In both scenarios, this will contribute to rising global food inflation." Following Russia's withdrawal in 2023 from an agreement that allowed grain exports via the Black Sea, Ukraine established a new maritime corridor for shipping grain and other goods from its Black Sea ports. To evade attacks, ships navigate along the Ukrainian coast, then pass through the territorial waters of Romania and Bulgaria, both EU members, before proceeding through the Bosphorus Strait to the Mediterranean Sea. Mike Verdin, a senior market adviser at CRM AgriCommodities, commented, "The market has until now relied on uninterrupted grain shipments, despite the war. What we are now witnessing is, in essence, the reopening of the original wound caused by the conflict." Ukraine offered Russia a truce to halt attacks on vessels transporting agricultural goods through the Black Sea, but Moscow rejected the agreement, demanding guarantees that its energy infrastructure would not be targeted, according to Ukrainian President Volodymyr Zelenskyy in late August. Ukrainian drone attacks have targeted, among other objectives, oil refineries deep within Russian territory. Russian President Vladimir Putin acknowledged the economic damage resulting from Ukrainian strikes and stated that he rejected ceasefire proposals from Kyiv as "unacceptable" and, in some cases, "strange," without providing further details. Conversely, Turkish Foreign Minister Hakan Fidan stated on August 31 that Turkey is in contact with Russia and Ukraine in an effort to revive the UN-brokered wartime grain deal, though it remains unclear whether these efforts will succeed. **Implications of Black Sea Attacks on Global Food Prices** Internationally traded food commodity prices are hovering near their highest levels since 2023, though they remain significantly below the peak reached in the wake of the conflict. Grain inventories are still abundant after record harvests in previous years. Romania, Bulgaria, and Serbia serve as useful alternative sources for wheat supplies from the Black Sea region. Nevertheless, the disruptions add to accumulating pressures in the global market. Farmers in some countries face shortages and rising prices for fertilizers and fuel due to repeated closures of the vital trade corridor through the Strait of Hormuz. Weather volatility adds another layer of uncertainty. Consecutive heatwaves have damaged crops in parts of Europe, leaving farmers with reduced harvests. The damage to corn is likely to make the region more reliant on imports of this crop, which is used as animal feed. In the United States, persistent drought conditions in the Great Plains and Corn Belt, two of the country's primary agricultural regions, have driven up basic food commodity prices. The return of the "El Niño" phenomenon is expected to cause further disruptions to the agricultural sector. **Impact of Disruptions on Ukraine and Russia** Grain represents a primary source of foreign currency for Ukraine, and disruptions in the Black Sea mean reduced farmer income, increasing pressure on the wartime economy. Given the challenges in exporting their crops, Russian farmers may scale back winter crop cultivation, which would affect global supplies in the future.
