A Serasa Experian study released October 27 warns a strong El Niño could cut Brazil's 2026/27 soybean harvest by 9.7%, from about 181 million to 164 million tonnes. Mato Grosso and Goiás account for nearly 80% of the estimated financial exposure, put at R$33 billion.
A potential loss of roughly 17.6 million tonnes would tighten global soybean and meal supply, lifting soybean meal and feed costs, though the outcome depends on how the El Niño evolves.
