Conab will publish its second 2026/27 crop survey on November 13 at 9:00, with updated estimates for planted area, production and yield of Brazil's main crops. The October first estimate put grain output at 367.1 million tonnes, 1.4% above 2025/26.
Soybeans and corn are the main focus of the report.
The Conab revision will show whether Brazil's supply outlook has changed since October, which feeds into export expectations and soybean and corn pricing. Market reaction depends on how far the numbers differ from the first estimate.
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.
After 770 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
