Last Thursday, CBOT soybean futures closed lower, and the market was closed on Friday for a federal holiday. The U.S. dollar index surged to a one-year high, with the probability of a December rate hike by the Federal Reserve rising to 85%, weighing on prices. Meanwhile, crude oil fell to a near-term low, dampening expectations for soybean biofuel demand. However, export data came in strong, with the USDA confirming private exporters sold 132,000 tonnes of new-crop soybeans to China. Weekly export sales posted a net increase of 424,900 tonnes, up 101% from the previous week, and China's resumed purchases provided some support to market sentiment.
