Report Summary 1. Report Industry Investment Rating No information provided in the document. 2. Core Viewpoints of the Report - For corn, maintain a bearish outlook. The USDA's supply - demand report shows an increase in the estimated planting and harvest areas of US corn in the 2025/26 season, a decrease in the estimated yield per acre, and an overall increase in production, which is higher than analysts' average expectations. In the domestic market, although low trade - grain inventories support prices, factors such as imported corn auctions, wheat for feed, approaching new - corn harvest seasons in North and Northeast China, and weak downstream demand lead to a decline in purchase prices. However, the slightly higher opening prices of new - season corn in some areas support market sentiment. [8][9][10] - For corn starch, also maintain a bearish outlook. The raw - material corn is in a new - old alternation period. Some enterprises have new maintenance due to insufficient raw - material supply, and the industry's operating rate is low. Although demand has slightly improved and inventory pressure has declined, the overall inventory is still high, and the substitution advantages of cassava starch and wheat starch squeeze the market demand for corn starch.
