Russia is cutting off Ukraine’s grain exports again, threatening a critical harvest and global food security

Russia has once again halted Ukraine’s grain exports, threatening vital harvests and global food security. The Black Sea has become a site of Russian aggression, with Russian forces targeting at least 50 Ukrainian cargo ships since June, killing over 30 civilians. This escalation follows a July 19 attack on a ship near Odesa that killed ten people. In retaliation, Ukraine struck Russia's Black Sea ports, including two major grain terminals in Novorossiysk, home to Russia's Black Sea naval fleet.

Ukraine's agricultural products, accounting for 90% of the country's exports by sea, rely heavily on Black Sea ports, making the blockade particularly devastating. Economists predict the blockade could cost Ukraine around 1–1.5% of its GDP by year's end. Ukraine anticipates a 60 million tonne grain harvest for 2026–27, but the export forecast has dropped to 38–40 million tonnes, a 12% reduction from earlier estimates.

The delays in exports could trigger a chain reaction, leading to storage shortages for crops and broken contracts with foreign buyers. This will result in reduced income for farmers and delayed tax payments to the government. Moreover, human rights groups allege Russia's aim to replace Ukraine as the global leader in agricultural exports, a strategy reminiscent of the Soviet-era Holodomor forced famine in 1932–33.

The current blockade shares similarities with Russia's initial blockade of Ukrainian ports at the start of the full-scale invasion in 2022. While the situation is not as dire at the moment, Ukraine's agricultural sector can absorb the current crisis to some extent. The Ukrainian government has approved an emergency support package and seeks additional aid from the European Commission.

Ukraine also engaged in talks with Poland to explore alternative export routes, but Poland imposed a ban on Ukrainian grain, citing concerns about cheaper Ukrainian imports flooding its market. Moldova has offered to allow 600,000 tonnes of Ukrainian grain transit by year-end, providing a potential alternative route.

However, exporting grain via land routes is considerably more expensive than by sea, and low water levels on the Danube River present additional challenges. The fate of Russia's own grain exports hangs in the balance, with Ukraine offering a temporary truce on Black Sea attacks. If Russia rejects Ukraine's proposal, the global market disruptions will worsen, posing significant threats to regional and worldwide food security.
