Irregular rainfall is creating concern as Brazil’s 2026/27 soybean planting advances in the Center-West. Cepea said climate uncertainty has limited declines in soybean prices, while ample Northern Hemisphere supplies have weighed on beans and weaker domestic demand for soybean meal and oil has pushed their prices lower.
Planting-weather uncertainty provides support to soybean prices by raising supply risk, while existing meal and oil stocks and softer demand pressure crush-product prices and processing margins.
