In the short term, the corn spot market shows regional divergence and a low-level oscillation pattern. The Northeast is stabilizing and rebounding, supported by policy purchases and reluctance to sell, but the delayed pressure from a bumper harvest limits the upside; North China is oscillating with a firm bias amid temporary tight supply and demand, but the price spread and demand constrain the upside; southern sales regions are weighed down by high inventories and import substitution, making it difficult to follow the rise. Overall, the market lacks a driver for a trend-based rally, and focus should be on the pace of grassroots grain sales, the strength of policy purchases, import arrivals, and feed enterprises' willingness to build inventories.
