Russian attacks on merchant vessels in the Black Sea have killed at least ten people and are threatening to choke off Ukraine's vital grain corridor near Odesa. The strikes, which hit multiple cargo ships over the past week, have pushed global wheat prices higher and raised fears of a renewed food supply crisis.
Attacks near Odesa
The latest assault targeted a civilian freighter about 30 nautical miles southwest of the port of Odesa. Ukrainian officials said the ship was struck by a Russian anti-ship missile, killing six crew members and wounding four others. Another vessel was hit two days earlier, leaving four dead. Both ships were carrying grain destined for markets in Africa and the Middle East.
Ukraine's navy confirmed that Russian forces have intensified patrols and launched coordinated strikes on commercial shipping lanes since early March. The corridor, established under a UN-brokered deal last year, had allowed Ukraine to export nearly 30 million tons of grain despite the war. That arrangement collapsed in July 2023, but Ukraine later carved out a temporary route hugging its coastline. The recent attacks have made that route nearly impassable.
Impact on grain corridor
The Black Sea grain corridor is now effectively closed for new shipments, according to maritime security analysts. Several shipping companies have suspended operations in the region, and insurance premiums for vessels transiting near Odesa have spiked. Ukraine's deputy infrastructure minister said the country's grain exports have dropped by roughly 40% since the attacks began.
Ukraine is one of the world's largest exporters of wheat, corn, and sunflower oil. The disruption comes at a critical time, as farmers in the Global South rely on Ukrainian grain to keep food prices stable. The United Nations has warned that any prolonged closure of the corridor could push millions into hunger.
Wheat prices rise
Global wheat futures on the Chicago Board of Trade jumped 8% in the days following the first attack, reaching their highest level in three months. Analysts at the International Grains Council said the price surge reflects market anxiety about supply shortages, especially if the corridor remains blocked through the spring planting season.
Egypt, one of the largest importers of Ukrainian wheat, has already begun seeking alternative suppliers from the European Union and Russia. But those options come at a higher cost, and the ripple effects are being felt across commodity markets. Corn and sunflower oil prices have also climbed.
What comes next
Ukraine's government is pressing its allies for more naval protection and air defense systems to safeguard the corridor. The European Union has condemned the attacks and pledged to increase maritime surveillance, but no concrete military support has been announced. Meanwhile, Russia has not claimed responsibility for the strikes, though Ukrainian intelligence says they were carried out by long-range bombers operating from Crimea.
The next few weeks will be critical. If the corridor remains blocked, Ukraine may be forced to rely entirely on overland routes through Europe, which are slower and more expensive. The UN is expected to release a new assessment of global food security risks later this month.
