Corn futures had their largest one-month rally on record in April 2021, with May corn up 31.1%, driven by Chinese import demand and a Brazilian drought. Export sales are near USDA's full-year estimate, and the safrinha crop was planted late with below-normal rainfall in Parana.
Tight US old-crop stocks and Brazilian safrinha losses point to pressure for higher USDA export estimates in the May WASDE. Strong cash bids and positive ethanol margins support corn prices.
