Chicago soybean futures fell 3.8% for the week, while Brazilian producers focused on planting the 2026/27 crop and reduced sales. Tornadoes and storms affected 23,600 people across 17 municipalities in Rio Grande do Sul, injuring five people and damaging an agricultural company; the report also noted that local soybean prices fell in November.
Slower Brazilian farmer selling may restrain nearby export availability, while the reported storms could pose localized risks to crop work or fields; the article gives no quantified crop damage. The weekly Chicago decline reflects bearish price pressure, but the story does not identify a specific new cause for that move.
