Drewry reports persistent congestion on the Danube that is reducing vessel availability in the Black Sea, particularly for smaller general cargo ships. About 70 vessels are waiting near Sulina, and Ukraine's grain exports fell almost 70% year on year in August.
Drewry estimates clearing the queue could take several weeks.
Constrained Danube capacity limits Ukrainian grain exports and keeps regional freight rates elevated through the export season. This supports prices for wheat and corn delivered to importers that rely on Black Sea origin.
