A farmdoc daily analysis overlays a timeline of U.S.-China trade actions on Central Illinois corn and soybean prices. It notes corn fell from $3.78 to $3.09 and soybeans from $10.34 to $7.84 over five months, with a partial rebound since mid-July.
The timeline documents how tariff escalation has pressured U.S. grain prices, reinforcing that trade headlines remain the key downside driver for soybeans and corn.
After 683 past bearish trade events, Corn moved a median -0.2% over 5 sessions (47% higher; middle half -1.7% to +1.6%), and +0.3% over 20.
After 803 past bearish trade events, Soybeans moved a median +0.0% over 5 sessions (51% higher; middle half -1.7% to +1.7%), and +0.9% over 20.
