CONAB increased its Brazil corn estimate to 131.9 million tonnes in its July report, 3.72 million tonnes above June. The safrinha crop was put at 104.5 million tonnes, while soybean output was estimated at 169.5 million tonnes with a record yield of 3,560 kg/ha.
Higher Brazilian corn supply adds to export competition for US and other origins in the second half of the year, which is bearish for corn and feed-grain prices.
After 1,102 past bearish report events, Corn moved a median -0.2% over 5 sessions (47% higher; middle half -1.8% to +1.3%), and +0.0% over 20.
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.
