ASAP Agri estimates Ukraine's 2026/27 agricultural exports at 29–47 million tonnes, depending on whether Black Sea ports operate. Rail has spare capacity of roughly 1.4–1.5 million tonnes per month, but needs more wagons, faster turnaround and fewer border delays.
Sea-port scenarios range from about 5.3 million tonnes under heavy restrictions to 17 million tonnes if Greater Odesa ports resume.
Export capacity from Ukraine determines how much grain reaches world buyers, so uncertainty over the ports supports wheat and corn prices. Reduced sea exports keep Black Sea supply constrained and tend to lift international prices relative to a reopening scenario.
