A Farmdoc study using 2015 to 2019 crop reporting district data shows the highest corn and soybean yields in the central Corn Belt. It also compares corn-to-soybean yield ratios across regions, which shape acreage decisions.
Yield ratios influence planting choices between corn and soybeans in future seasons, which can affect supply expectations. The report has little immediate price impact.
After 3,207 past report events, CORN moved a median +0.2% over 5 sessions (54% higher; middle half -1.3% to +1.7%), and +0.5% over 20.
After 2,389 past report events, SOY moved a median 0.0% over 5 sessions (50% higher; middle half -1.6% to +1.9%), and +0.1% 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.
