Conab lowered its 2026/27 Brazilian grain crop estimate to 366.1 million tonnes from 367.1 million in October. Soybean (181.6 Mt) and corn (148 Mt) forecasts were unchanged, and the cut came from rice and wheat.
Rice output is now seen at 10.5 Mt, down 4.7% year on year, after heavy rain in Rio Grande do Sul.
Lower rice and wheat output tightens domestic supply and supports prices for those grains, while soybean and corn balances are unchanged. The cut is small, so the effect on world prices is limited.
After 88 past bullish report events, Rough Rice moved a median +0.0% over 5 sessions (50% higher; middle half -1.5% to +2.1%), and +2.5% over 20.
