Conab left its Brazil soybean estimate unchanged at 181.6 million tonnes and corn at 148 million tonnes. Soybean planting was about 75% complete, with recent rain helping conditions in central-north areas.
USDA estimates Brazil soybeans at 186 million tonnes and corn at 141 million after raising corn by 2 million tonnes.
Conab and USDA differ on Brazil's corn outlook, and analysts see Conab's second-crop corn as possibly optimistic given high fertilizer, fuel and interest costs. Any shortfall would support corn and meal prices against US supply.
After 563 past neutral report events, Soybeans moved a median -0.1% over 5 sessions (48% higher; middle half -1.7% to +1.6%), and -0.1% over 20.
