Chicago wheat futures climbed to a one-week high on May 4, 2023, recovering from multi-month lows as renewed Russia-Ukraine tensions cast doubt on the Black Sea export corridor. Soybeans slipped and corn was almost flat under pressure from US planting.
The Kremlin drone accusation and Ukraine's comments on the deal were the main drivers.
Doubts about Black Sea supply flows support wheat prices after a weak stretch. Corn and soybeans are weighed down by faster US planting, which limits their upside.
After 361 past bullish geopolitics events, WHEAT moved a median +0.7% over 5 sessions (58% higher; middle half -1.4% to +3.7%), and +1.3% over 20.
After 53 past bearish geopolitics events, SOY moved a median -0.3% over 5 sessions (47% higher; middle half -1.9% to +1.2%), and +1.0% over 20.
