Russian and Ukrainian forces have intensified strikes on each other's Black Sea ports and vessels, sharply reducing grain export capacity from both countries and raising concerns over global food supplies.

As of early September 2026, Russian attacks have reduced vessel traffic at Ukraine's key Odesa-region ports to about one ship per day. Strikes on infrastructure in Odesa and Chornomorsk have further hampered operations, following a pattern that cut monthly grain shipments from roughly six million tons to four million tons or less.

Ukraine responded with strikes on Russian facilities, including a major attack on Novorossiysk on August 12 that damaged multiple grain terminals and halted operations at three large sites handling around 25 million metric tons of exports annually. Additional Ukrainian strikes damaged terminals at Taman and restricted navigation in the Sea of Azov, taking more than 90 percent of Russia's Azov-Black Sea grain export capacity offline.

Both nations rank among the world's top grain exporters. The disruptions have driven wheat futures to their highest levels in three years. Ukrainian officials reported that Russia struck port infrastructure and energy facilities supplying the Odesa area on September 1, while Russia has accused Ukraine of targeting civilian shipping.

Russia declined a Ukrainian proposal last week to pause Black Sea strikes aimed at averting a broader food crisis. The mutual campaign has trapped millions of tons of grain and forced reliance on costlier alternative routes such as the Danube ports for Ukraine and more distant facilities for Russia.

Industry analysts note that carryover stocks in Ukraine could reach nine million tons or higher due to export bottlenecks, pressuring domestic prices and farmer incomes. Global markets face risks of shortages if the blockade persists into the new harvest season.
