Soybean prices fell from about $13 a bushel in early October to under $12.50 by October 20. USDA's October 9 WASDE raised the 2026/27 US soybean crop to a record 4.56 billion bushels and lifted yield to 53.1 bushels per acre.
Favourable weather in Brazil and Argentina added to supply expectations.
A record US crop and strong South American prospects increase supply ahead of demand, which keeps soybean prices under pressure.
