Grain exports from Ukraine have roughly halved since late July as Odesa-region ports have not operated due to Russian strikes. Farmers are selling wheat at a loss because domestic prices have fallen with the surplus, and some are holding stock in storage.
Idle Black Sea ports leave Ukrainian grain stranded inland, depressing local prices and pushing more supply into storage rather than world markets. Any reopening would add supply to global wheat and corn markets, which is bearish for prices.
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.
