1. Report Industry Investment Rating There is no information provided regarding the report industry investment rating. 2. Core Viewpoint - The corn market is in a stage of oscillating downward, and the later price center is expected to decline. Due to high yields, imported corn supplements the market supply, and the overall supply is sufficient. The price difference between corn and wheat remains in the substitutable range, with wheat being widely used as a substitute for corn. Alongside the substitution of millet and other grains, these factors suppress the corn price. The planting area of new crops is high, and the expected yield per unit is good, so the new crop yield is still expected to be abundant. The lowest planting cost of the new crop on the futures market is about 2,000 yuan/ton, and the cost center continues to shift downward. Under multiple negative factors, it is expected that c2509 will oscillate downward, and the later price center is expected to shift downward [7]. 3. Summary by Directory Domestic Corn Supply - Supply: The domestic corn price continues to oscillate weakly, and the growth of new - season corn is good. The current main variable is the weather during the growth period, especially rainfall. The NDVI data shows that the growth of corn in Northeast China is significantly better than in previous years, while in North China, although affected by extreme weather, the growth is still around the annual average. Overall, the expected yield per unit of corn in the main production areas is good [9][10]. - Import: The scale of corn imports has significantly decreased. In June 2025, the total corn import volume was 156,400 tons, a year - on - year decrease of 82.99% and a month - on - month decrease of 3.21 tons. From January to June 2025, the total corn import volume was 785,300 tons, a year - on - year decrease of 92.88%. The USDA estimates that China's corn imports in the 2024/25 season will be 4 million tons, lower than 23.41 million tons in the 2023/24 season [17][19][20]. - Substitutes: Feed enterprises are purchasing wheat to replace corn, and the substitution pressure of imported substitutes is decreasing. The price difference between corn and wheat in North China is near parity, and wheat has a high cost - effectiveness, exerting great pressure on the feed - use substitution of corn. In June 2025, the import volume of barley decreased by 23.83% year - on - year, and the import volume of sorghum decreased by 32.71% year - on - year [29][30]. Demand - Feed and Livestock Farming: The feed demand in the livestock farming industry is rigid, but the breeding profit is average. In June 2025, the national industrial feed production was 27.67 million tons, a month - on - month decrease of 0.1% and a year - on - year increase of 6.6%. The inventory of breeding sows, the parent - stock of white - feather broilers, and the hatching volume of laying - hen chicks are all at high levels, indicating a rigid feed demand. However, the breeding profit of self - breeding and self - raising pigs is at a low level, the profit of broiler breeding is seasonally rising, and the profit of laying - hen breeding has deteriorated [34][35][36]. - Deep - processing: The operating rate of corn starch enterprises in Heilongjiang has increased significantly, but the deep - processing production profit is severely in the red. The operating rate of major corn starch enterprises nationwide has rebounded to a neutral level, with Shandong and Heilongjiang showing relatively high rates. The corn starch production has also increased, but the downstream提货量 is low, and the production profit is severely in the red. The consumption of corn by corn alcohol enterprises has slowed down, and the operating rate has reached a new low [55][56]. Inventory - Corn Trade and Inventory: The inventory of trade channels and downstream users is gradually decreasing, and the starch inventory is significantly high. As of August 8, the inventory of the four northern ports continued to decline, and the domestic trade inventory of southern ports fluctuated downward. The inventory of feed enterprises continued to decrease, and the inventory of deep - processing enterprises decreased seasonally. The starch inventory of major starch enterprises continued to reach a new high in the past eight years [83][84][85]. Basis and Spread - Basis: The report provides the basis data of corn 01, 05, 09 contracts at Jinzhou Port and the basis data of starch 01, 05, 09 contracts in Jilin area on August 14, 2025 [117][119][121]. - Spread: The report provides the spread data of corn 5 - 9, 9 - 1, and the spread data of starch 1 - 5, 5 - 9, 9 - 1, as well as the spread data between corn and starch 01, 05, 09 contracts [127][128][129]. Corn Warehouse Receipt Quantity - As of August 14, 2025, the corn warehouse receipt quantity was 222,298 hands, and the corn starch warehouse receipt quantity was 25,000 hands [140]. Industrial Chain Operation Suggestions - Traders: For procurement management, build inventory and seek to buy corn at low prices. Use a 100% hedging ratio, buy the c2509 - C - 2400 option at an entry price of 8. For inventory management, sell corn at high prices and use a 100% hedging ratio, short the c2509 contract at an entry price of 2300 [4]. - Downstream Enterprises: For procurement management, when in need of corn raw materials and worried about price increases, use a 100% hedging ratio, buy the c2509 - C - 2400 option. For inventory management, when the raw material inventory is high and worried about price drops, use a 100% hedging ratio, short the c2509 contract at an entry price of 2300 [4].
