A study published by MIT researchers finds that the expansion of corn and soybean production in the US Midwest over the late 20th century may have contributed to cooler, wetter summers in the region. The analysis shows a strong correlation between areas of increased crop production, higher rainfall and lower temperatures.
The finding is a research result about climate effects and does not directly move crop supply or prices in the near term. It may matter for long-run weather modeling of Midwest yields.
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, Soybeans moved a median 0.0% over 5 sessions (50% higher; middle half -1.6% to +1.9%), and +0.1% over 20.
