The September USDA report left Black Sea wheat balances unchanged, with Ukraine's barley crop raised 0.5 MMT to 10.5 MMT. Russia's corn crop and exports were cut by 1 MMT and 0.2 MMT on drought, and the regional grain crop fell 0.7% to 204.6 MMT.
Russian corn and barley cuts tighten Black Sea supply, supporting corn prices, while the unchanged wheat outlook leaves wheat prices neutral.
After 1,040 past bullish report events, Corn moved a median +0.5% over 5 sessions (62% higher; middle half -0.9% to +2.0%), and +0.8% over 20.
