Ukraine scrambles to reroute grain as Russian strikes shut Black Sea ports

Ukraine is scrambling to reroute its grain exports through rail, road, and river corridors after Russian attacks effectively shut down the country's Black Sea ports during peak harvest season, with the agriculture minister warning that alternative channels will take weeks to become operational and can handle only half of normal volumes.

Ports Under Siege

Russia has intensified missile and drone attacks on foreign-flagged civilian vessels in the Odesa port hub, which handles most of Ukraine's grain shipments. In July alone, Ukraine recorded 35 attacks on vessels in ports and 22 on those at sea, along with 67 strikes on port facilities — compared with 14 attacks on vessels in all of 2025, according to Reuters. Shipowners have suspended calls at ports around Odesa, with no vessels entering for nearly two weeks as the summer harvest enters full swing.reuters

"The situation is exceptionally complicated. In certain aspects, it is even more difficult than in March–April 2022," agriculture minister Taras Vysotskyi told Reuters, referring to the early months of Russia's full-scale invasion. Direct losses for Ukraine's agricultural sector could reach between $1.5 billion and $3 billion this year, he said.reuters

Rail Becomes the Lifeline

State rail operator Ukrzaliznytsia has restricted cargo shipments to Odesa and Chornomorsk while redirecting grain wagons toward Danube ports and western border crossings. The number of grain wagons heading to Greater Odesa ports fell from 4,525 to 1,356, while traffic toward the Danube ports rose from 167 to 1,141 wagons. However, Vysotskyi warned that alternative routes would not reach "a more or less stable operational level" until the end of August at the earliest, and even then could handle only 50% to 55% of Black Sea ports' monthly capacity of about 6 million tonnes.ukragroconsult+2

The rerouting carries steep costs. UkrAgroConsult estimates wheat delivery to Constanța may cost $60–70 per tonne in some cases, while a 30% indexation of domestic rail freight tariffs took effect on August 1. Ukrainian producers are already seeing oilseed and grain prices decline by 30% on average. The drought-hit Danube, where water levels are at historic lows, will not play a major role until October, Vysotskyi said.reuters+2

Wider Economic Fallout

The logistics crunch extends beyond agriculture. Ukraine's Pivdennyi GOK iron ore mine temporarily suspended operations due to the inability to ship product through blocked ports, idling thousands of workers. On the Russian side, Ukrainian drone strikes have damaged the Demetra grain terminal at Taman port, and maritime traffic through the Kerch Strait has been suspended since July 10.safety4sea+2

On Tuesday, Ukraine's government approved adjusting minimum export prices as an emergency measure to support farmers. Vysotskyi called on allies to help ensure Black Sea security, warning that global food prices could spike. "Food will become more expensive, and for the poorest people, it may become simply unaffordable," he said.reuters
