Conab's March monitoring bulletin reported that heavy rain in March favored second-crop corn development in Brazil's Center-North and part of the Northeast but delayed corn sowing and soybean harvest and logistics. Low rain damaged first-crop crops in Central-South Bahia and Northern Minas Gerais, and Rio Grande do Sul remained water-restricted.
Vegetation indices indicated favorable conditions for second-crop corn nationally.
Favorable second-crop corn conditions support a larger Brazilian corn supply, while harvest delays can slow soybean marketing and add logistics friction. The net effect on prices is modest.
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.
After 324 past neutral weather events, Soybeans moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
