University of Illinois professor Gary Schnitkey advises farmers not to base budgets on recent high yields, noting that yield shortfalls will recur. He expects 200-bushel corn and 60-bushel soybeans to become more common.
The article cites the record 2017 US corn average of 176.6 bushels and a soybean average just over 49 bushels.
The record 2017 crop is already known, and the comments are long-term outlook rather than new supply news, so they are unlikely to move prices.
After 770 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
After 563 past neutral report events, Soybeans moved a median -0.1% over 5 sessions (48% higher; middle half -1.7% to +1.6%), 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.
