NDSU notes that North Dakota, most of South Dakota and northwest Minnesota have drought conditions, with tight 2020-21 ending stocks putting extra focus on weather. The article explains that Drought Monitor categories D0 to D4 reflect soil depth, and that drought does not always cut yields if rains are well timed.
It also warns that localized drought can complicate farm marketing plans.
Tight ending stocks mean drought in the northern Plains could move corn and soybean prices if yields fall, but the impact depends on timing of rain during flowering and seed development.
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 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
