Corn futures prices surged on Monday (9/9) at the B3 derivatives exchange in São Paulo, driven by rising external commodity prices and stronger domestic cereal prices. The November/24 contract surpassed a key resistance level, closing at around R$67 per bag, with potential targets and support levels identified by Agrifatto. The Cepea Corn Indicator also saw a slight increase, while CBOT corn futures for December/24 rose by 0.25%, influenced by wheat and soybean prices. Brazil exported 1.55 million tons of corn in the first five business days of September/24, although the average price of exported corn hit a 12-month low.
