Ukraine Grain Exports Stalled by Danube Sulina Canal Backlog
8/27/2026, 2:16:12 AM
The Bottleneck at Sulina Canal
Up to 70 vessels are queued near the Danube’s Sulina Canal, awaiting passage to Ukrainian river ports. A shortage of pilots and the canal’s limited capacity restrict traffic to roughly five to seven vessels per day, while the actual throughput for grain-bound ships is only two to three vessels daily. Higher-priority cargoes such as fuel further crowd the waterway, extending wait times for grain carriers.
Recent Export Figures
Ukraine’s agriculture ministry reports that between August 1 and August 21 the country exported 539,000 tons of grain, far below the 1.73 million tons moved in the same period a year earlier. The sharp decline reflects the shift from Black-Sea ports—normally handling about 90 % of Ukraine’s grain—to the much smaller Danube route.
Causes and Constraints
Russian attacks have effectively blocked Black-Sea terminals, forcing shipments to reroute through Danube ports whose infrastructure was already strained by historic summer droughts that lowered water levels and forced vessels to travel lighter. Poor weather is expected to close the Sulina Canal for about two days, further limiting the already tight schedule.
Official Assessments and Costs
Consultancy ASAP Agri warned on August 25 that each day of delay can cost up to $8,000, adding pressure to already high freight rates. The same alert noted that more than 50 vessels were waiting as of that date, a figure that grew to about 70 by August 26. Operations manager Katerina Kononenko of Avalon Shipping described the situation as a “serious setback,” citing the canal’s reduced traffic capacity. State railway operator Ukrzaliznytsia said grain-transport volumes to Danube ports in August were eleven times higher than in July, underscoring the surge in reliance on the river route.
Outlook
ASAP Agri cautioned that deteriorating weather could worsen congestion in the coming days, potentially extending ship wait times further. With limited daily vessel throughput and ongoing Russian restrictions on Black-Sea access, Ukraine’s grain export capacity via the Danube remains well below pre-war levels, a factor that could keep global grain prices elevated.
