Chicago wheat, corn, and soybean futures experienced a rise on Monday, driven by buying interest after recent price drops. The increase is also attributed to the anticipation of record-large U.S. soybean crushings. However, the gain is capped by concerns over demand from China and the condition of South American soybean crops. A significant purchase of 804,000 metric tons of wheat by Saudi Arabia also supported the market. Despite reaching its highest level since June, corn faces resistance at $4.50 and needs new information to surpass this level.
