Iowa Farm Bureau's weekly report shows Iowa corn harvest at 66 percent complete as of November 1, well behind the four-year average. Soybean harvest has caught up to average, and several southern and Cornbelt states are much further along.
A delayed corn harvest can slow marketing and delay drying and transport, which can briefly support local basis. The effect on futures is small.
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.
