Chicago wheat rallied on Friday on market talk that Russia might halt wheat exports. Corn futures climbed for a second straight week on strong Chinese demand.
Rumors of a Russian export halt threaten supply from a major exporter, lifting wheat prices, while steady Chinese buying supports corn.
After 431 past bullish trade events, Wheat (SRW) moved a median +0.0% over 5 sessions (50% higher; middle half -1.3% to +2.1%), and +0.5% over 20.
After 729 past bullish trade events, Corn moved a median +0.4% over 5 sessions (56% higher; middle half -1.1% to +1.8%), and +0.5% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
Friday's talk of a Russian export halt and Black Sea doubts began the rally and set up the gap higher on Monday, but it falls before the measured one-day window.
