Ukraine's Agrarian Policy Ministry is planning for a scenario in which full access to Black Sea ports is unavailable until the new marketing year starting July 1, 2027. The minister said there is no confirmation of a reopening date and that logistics costs are the main reason for low domestic prices, with about 60 million tonnes of grain available against roughly 30 million tonnes exportable.
A prolonged port closure keeps a large Ukrainian grain surplus off world markets, which supports global wheat and corn prices in the near term. It also widens the domestic-to-world price gap, with logistics costs absorbing most of the margin.
After 283 past bullish logistics events, Wheat (SRW) moved a median -0.2% over 5 sessions (46% higher; middle half -1.4% to +1.3%), and -0.1% over 20.
