MinnStar Bank reports that a warm September pushed Upper Midwest corn and soybeans rapidly toward maturity, with soybean harvest 50% or more complete in many areas. Waseca recorded 5% above-normal growing degree days, and yields varied widely by rainfall timing.
Early maturity and rapid harvest progress point to normal timing and no major supply shock, leaving prices with limited directional impact.
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.
