Corn and wheat futures edged higher overnight on possible harvest delays and the ongoing Russia-Ukraine war. A temporary ceasefire in Kherson ended, and rainfall was forecast for parts of the US Corn Belt.
Black Sea conflict risk supports wheat prices given Russia and Ukraine's export roles. Rain-related harvest delays could slow corn supply, but the gains are small.
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 31 past neutral geopolitics events, CORN moved a median -0.3% over 5 sessions (42% higher; middle half -2.3% to +1.1%), and +0.2% over 20.
