Soybean planting for the 2026/27 crop in Brazil neared 50% of the area in October, ahead of the pace of the past five seasons, according to Itaú BBA. Irregular rains and lower soil moisture in parts of the Centre-West remain key risks, and early-November rainfall will be decisive for the crop and the second-crop window.
Faster planting reduces the risk of a crowded November sowing, but dry spells in Mato Grosso could cut yields and delay corn planting, tightening future Brazilian soy and corn export supplies.
After 324 past neutral weather events, SOY moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
After 445 past neutral weather events, CORN moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
