Ukraine redirects grain exports as Black Sea blockade cuts shipments

Ukraine is scrambling to reroute grain exports through the Danube River and eastern European rail corridors after Russian attacks on Black Sea ports caused shipments to plummet by 76% year-on-year in August, according to the state railway operator Ukrzaliznytsia.

So far this month, only 201,700 metric tons of grain have been shipped for export, a fraction of normal volumes. The operator described the pace as "extremely low" due to the seaport blockade, which has effectively halted maritime trade since late July.

In response, export cargo is being redirected to Danube river ports and rail crossings with Poland, Hungary, Slovakia, and Romania. Shipments to Danube ports have surged to 91,100 tons in August—11 times the July level—while volumes to eastern European countries rose 81% to 126,000 tons.

Despite these gains, overall volumes remain far below capacity. Valeriy Tkachev, deputy head of Ukrzaliznytsia's commercial department, told traders that exports via European routes could increase significantly. During a similar blockade in 2022-23, up to 650 grain wagons crossed Ukraine's western borders daily at peak times, compared with an average of 140 per day this August. Most wagons were bound for Romania and Poland.

Danube exports could also expand, but are constrained by low water levels, administrative bottlenecks, and a shortage of captains and pilots. Frequent air-raid alerts further disrupt operations—on Tuesday alone, 15 alerts lasting a combined 11 hours halted work. Russia has intensified drone attacks on Danube ports, with the latest strike overnight targeting Izmail port.
