Harvest is nearly complete in north-central Illinois after a relatively dry fall. A local farmer reported very good soybean yields, while corn yields varied and were affected by excess rain, heat after pollination, and weaker grain fill; USDA said 86% of Illinois corn and 91% of soybeans were harvested.
The local report points to weaker corn yields but strong soybean performance, with limited implications beyond the area. The mixed results are unlikely to move national prices on their own.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
After 363 past bearish weather events, Soybeans moved a median -0.6% over 5 sessions (42% higher; middle half -2.5% to +1.1%), and -0.2% over 20.
