Report Industry Investment Rating There is no information provided regarding the report industry investment rating in the given content. Core Viewpoints - Corn prices are likely to decline in the short term but have limited downside space, with support at the 2000 price level. It is recommended to focus on long - term long - buying opportunities for corn [2][5]. - Different participants in the industry are given corresponding operation suggestions. Traders for procurement management should build inventory, buy out - of - the - money call options to prevent price increases, and sell put options at the support level to reduce costs; traders for inventory management with inventory should directly short futures and sell a portion of put options at the support level; downstream enterprises for procurement management should buy out - of - the - money call options to prevent price increases and sell put options at the support level to reduce costs; downstream enterprises for inventory management with high raw material inventory should directly short futures and sell a portion of put options at the support level [2]. - Key data to focus on include the selling pressure at the grass - roots level, changes in the inventory of the breeding industry, and the price difference between corn and wheat [2]. Summary by Directory Supply Domestic Corn Supply - Continuous rainy weather has intensified the selling pressure in Henan and other regions, resulting in a significant impact from the overall market supply. The new - season corn in the Northeast and North China regions has a large amount of harvest and listing, with high enthusiasm for selling grain at the grass - roots level. The arrival volume at the four northern ports and the number of vehicles arriving at Shandong's deep - processing plants have reached historical highs [7][8]. Corn Import - The scale of corn imports has significantly decreased. In August 2025, the total import volume of ordinary corn was 40,000 tons, a three - year low. From January to August 2025, the cumulative import volume of ordinary corn was 890,000 tons, a decrease of 92.92% compared with the same period last year. The estimated import volume of corn in the 2024/25 season is 3 million tons, lower than the 23.41 million tons in the 2023/24 season [17][18][19]. Substitutes - The price difference between corn and wheat has moved out of the substitutable range, and the substitution pressure of imported substitutes has decreased. The price of wheat has risen this week. The price difference between corn and wheat in North China is around - 290 yuan/ton. In August 2025, the import volume of barley decreased by 45.22% year - on - year, and the import volume of sorghum decreased by 40.00% year - on - year [22][23].

The proportion of corn used in compound feed was 32.9%, a year - on - year increase of 1.7 percentage points. The inventory of breeding capacity is at a high level, but the self - breeding and self - raising profit of pigs, the breeding profit of broilers, and the breeding profit of laying hens are all in a poor state [31][32][33]. Corn Processing - The operating rate of corn starch enterprises has continued to recover, and the deep - processing production profit has improved rapidly. The operating rate of major corn starch enterprises in the country has returned to a neutral level, with the operating rate in Shandong and Heilongjiang regions at a relatively high level. The production of corn starch has increased, and the downstream pick - up volume has recovered. The production profit of corn starch has recovered rapidly, and the profit of corn alcohol manufacturing in major producing provinces has also improved [47][48]. Inventory Channel and Downstream Inventory - Channel and downstream inventories have started to replenish, and the starch inventory is significantly high. As of October 10, the inventory at the four northern ports has stopped falling and started to rise, but it is still at a low level. The inventory of feed enterprises has stopped falling and stabilized, and the inventory of deep - processing enterprises has continued to rise seasonally. The starch inventory of major starch enterprises has increased and is at a high level in the past eight years [75][76][77]. Basis and Spread - The report provides data on the basis and spread of corn and starch contracts such as C2601, C2605, and C2609, including the basis of corn and starch at different ports and regions, and the spread between different contracts [106][116][117]. Warehouse Receipt Quantity - As of October 16, 2025, the number of corn warehouse receipts was 222,298, and the number of corn starch warehouse receipts was 25,000 [126].
