Corn rose on May 14, 2021, after USDA cut its 2020/21 Brazilian corn estimate in the May WASDE. Persistent drought in southern Brazil after delayed planting is expected to limit yields on about 40% of affected acres.
USDA also reported new-crop export sales of 82.1 million bushels, a weekly high.
Brazilian production losses tighten global corn supply and support export demand for US corn. This adds upward pressure on corn prices.
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.
