The September Grain Stocks report raised 2020/21 soybean ending stocks by 81 million bushels to 256 million, forcing USDA to revise its October WASDE. The October update lifted U.S. soybean production 80.8 million bushels to 4.2 billion bushels on higher planted area and yield, and soybean prices fell sharply for both the old and new crop years.
Higher old-crop soybean stocks and a larger new crop shift the balance toward surplus, which lowers soybean meal and oil values and reduces the cost of protein for feed buyers.
