Brazilian corn trading is slow as buyers hold back, with prices in Rio Grande do Sul, Santa Catarina, Paraná and Mato Grosso do Sul reported in local reais per bag. Rain, cold and low light are slowing crop development in southern Brazil, and Paraná planting reached 94% of its area.
Ample domestic supply versus cautious demand keeps Brazilian corn prices soft, while southern weather delays add some risk to the 2026/27 crop.
After 357 past bearish weather events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.3%), and -0.5% over 20.
