1. Report Industry Investment Rating - No information provided 2. Core Views - For corn, the USDA report predicts that the US corn production in the 2025/26 season will reach a record - high of 16.814 billion bushels, and the ending stocks will also reach the highest level in seven years. With the progress of US corn harvest, the supply pressure will gradually increase. However, the early harvest results are mixed, leading to an expectation of a possible downward adjustment in US corn production. In the domestic market, the new grain harvest area in Liaoning and Heilongjiang in the Northeast region is expanding, and farmers' enthusiasm for selling grain is high. As the supply of new corn increases, the downstream demand is relatively weak, the losses of deep - processing enterprises are intensifying, and the purchase price has been lowered. The new - season corn listing still restricts the futures market [2]. - For corn starch, the market is currently weak, and enterprises are still in a loss state. The industry's operating rate is generally low. Due to a slight improvement in pre - holiday demand, the inventory continues to decline. As of September 24, the total starch inventory of national corn starch enterprises was 1.139 million tons, a weekly decrease of 61,000 tons, a weekly decline of 5.08%, a monthly decline of 13.58%, and a year - on - year increase of 28.85%. However, the industry inventory is still high, and the substitution advantages of tapioca starch and wheat starch are still significant, squeezing the market demand for corn starch. Although there has been a slight rebound at low levels recently, the demand support is insufficient, and the corn starch market maintains a bearish outlook [3]. 3. Summary by Relevant Catalogs 3.1 Futures Market - Corn futures: The closing price of the active contract of corn starch futures was 2,469 yuan/ton, up 22 yuan; the closing price of the active contract of CBOT corn was 425.75 cents/bushel, up 4 cents. The net long non - commercial position of CBOT corn decreased by 36,169 contracts, and the total position increased by 51,949 contracts [2]. - Corn starch futures: The closing price of the active contract was 2,164 yuan/ton, up 6 yuan. The net long position of the top 20 futures holders decreased by 251 contracts, and the registered warehouse receipts decreased by 20 contracts [2]. 3.2 Spot Market - Corn: The average spot price was 2,357.25 yuan/ton, up 0.78 yuan; the average price of imported corn was 1,939.55 yuan/ton, down 0.47 yuan [2]. - Corn starch: The factory - quoted price in Changchun was 2,560 yuan/ton, unchanged; in Shijiazhuang was 2,730 yuan/ton, unchanged; in Weifang was 2,800 yuan/ton, unchanged [2]. 3.3 Upstream Situation - The predicted sown areas of corn in the US, Brazil, Argentina, China, and Ukraine were 425.26 million hectares, 22.6 million hectares, 7.5 million hectares, 295 million hectares, and 32 million hectares respectively; the predicted yields were 35.89 million tons, 131 million tons, 53 million tons, 44.3 million tons, and 1.5 million tons respectively [2]. - The corn inventory in southern ports decreased by 55,000 tons to 601,000 tons, and the deep - processing corn inventory decreased by 147,000 tons to 2.34 million tons [2]. 3.4 Industry Situation - The monthly import volume of corn was 60,000 tons, a decrease of 10,000 tons; the monthly export volume of corn starch was 15,940 tons, an increase of 1,440 tons [2]. - The monthly output of feed was 29.272 million tons, and the corn starch processing profit in Shandong was - 72 yuan/ton, a decrease of 12 yuan [2]. 3.5 Downstream Situation - The deep - processing corn consumption decreased by 1,100 tons to 115,630 tons, and the alcohol enterprise operating rate decreased by 1.28 percentage points to 50.31% [2]. - The starch enterprise operating rate increased by 2.21 percentage points to 50.36%, and the corn starch processing profit in Hebei was 7 yuan/ton, an increase of 2 yuan [2]. 3.6 Option Market - The historical volatility of corn in 20 days was 10%, unchanged; the implied volatility of at - the - money call options was 10.5%, an increase of 0.66 percentage points; the implied volatility of at - the - money put options was 10.5%, an increase of 0.67 percentage points [2]. 3.7 Industry News - As of September 22, the grain export volume of Ukraine in the 2025/26 season was 5.82 million tons, higher than 5.251 million tons a week ago but lower than 9.764 million tons in the same period last year [2]. - Private exporters reported selling 122,947 tons of US corn to Mexico, with 100,593 tons to be delivered in the 2025/26 season and 22,354 tons in the 2026/27 season [2].

Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Views - **Corn**: In the US, although the estimated corn production in 2025 is expected to reach a record high, it is still lower than the USDA's August forecast, adding expectations of a later USDA production cut. In the domestic market, with the approaching new - season corn listing in the Northeast, the continuous release of reserve - rotated corn, weakened confidence of traders, and sufficient stockpiles of grain - using enterprises, the corn market has weak trading and prices are in a weak adjustment. The corn market is under pressure [2]. - **Corn Starch**: During the transition period between old and new corn, some enterprises have limited production and maintenance, leading to a decline in the industry's operating rate. Supply pressure has decreased, demand has slightly improved, and inventory pressure has declined. However, the industry inventory is still high, and the substitution advantages of cassava starch and wheat starch are still good, squeezing the demand for corn starch. The starch market remains in a low - level oscillation and is still regarded as bearish [3]. 3.

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - For corn, domestically, as the new - season corn in the Northeast is approaching the listing period, reserve - rotation corn is continuously put into the market, weakening traders' confidence in price support and accelerating the sale of remaining grains. With poor breeding profits, sluggish feed sales, and low enthusiasm from feed enterprises to purchase old grains, and deep - processing enterprises relying mainly on contract grains, the market trading is relatively light, and prices continue to run weakly. Recently, due to short - covering, corn futures prices have rebounded from the low level [2]. - For corn starch, as previously overhauled enterprises resume work, the operating rate in the corn starch industry has rebounded, increasing supply - side pressure. The overall market trading shows no obvious trend, and the supply - demand pattern is clearly oversupplied with high inventory pressure. Affected by the corn rebound, starch prices have risen in a volatile manner [3]. 3. Summary by Relevant Catalogs 3.1 Futures Market - Corn futures: The closing price of the active contract is 2200 yuan/ton, the 1 - 5 monthly spread is - 66 yuan/ton, the trading volume of the active contract is 948162 lots, the net long position of the top 20 futures holders is - 75739 lots, the registered warehouse receipt volume is 66608 lots, and the CS - C spread of the main contract is 212 yuan/ton [2]. - Corn starch futures: The closing price of the active contract is 2505 yuan/ton, the 11 - 1 monthly spread is - 30 yuan/ton, the trading volume of the active contract is 196158 lots, the net long position of the top 20 futures holders is - 41054 lots, and the registered warehouse receipt volume is 7450 lots [2]. 3.2 Outer - Disk Market - CBOT corn: The closing price of the active contract is 420 cents/bushel, the total position is 1456701 lots (weekly), and the non - commercial net long position is - 70940 lots (weekly) [2]. 3.3 Spot Market - Corn: The average spot price is 2363.33 yuan/ton, the fair - market price at Jinzhou Port is 2280 yuan/ton, the CIF price of imported corn is 1929.52 yuan/ton, and the international freight of imported corn is 43 US dollars/ton [2]. - Corn starch: The ex - factory quotes in Changchun, Weifang, and Shijiazhuang are 2660 yuan/ton, 2900 yuan/ton, and 2830 yuan/ton respectively. The basis of the main corn starch contract is 155 yuan/ton, and the basis of the main corn contract is 163.33 yuan/ton [2]. 3.4 Upstream Situation - The predicted annual corn production in the US, Brazil, Argentina, China, and Ukraine is 398.93 million tons, 131 million tons, 53 million tons, 295 million tons, and 30.5 million tons respectively. The predicted sown areas in the US, Brazil, Argentina, and China are 35.12 million hectares, 22.6 million hectares, 7.5 million hectares, and 44.3 million hectares respectively [2]. - Corn inventories at southern and northern ports are 770,000 tons and 1.75 million tons respectively, and the deep - processing corn inventory is 2.942 million tons [2]. 3.5 Industry Situation - The imported corn volume is 60,000 tons, and the exported corn starch volume is 15,940 tons [2]. 3.6 Downstream Situation - The monthly feed production is 2.8273 million tons, the sample feed corn inventory days are 28.13 days, the deep - processing corn consumption is 1.1402 million tons, the alcohol enterprise operating rate is 42.87%, and the starch enterprise operating rate is 51.01% [2]. - The corn starch processing profits in Shandong, Hebei, and Jilin are - 122 yuan/ton, - 51 yuan/ton, and - 81 yuan/ton respectively [2]. 3.7 Option Market - The 20 - day and 60 - day historical volatilities of corn are 7.46% and 6.32% respectively. The implied volatilities of at - the - money call options and at - the - money put options of corn are 10.02% and 10.02% respectively [2]. 3.8 Industry News - As of August 28, the sowing progress of the first - season corn in the central and southern regions of Brazil in the 2025/26 season has reached 6.7%, compared with 3.2% a week ago and 7.7% in the same period last year [2]. - As of August 28, the harvesting of the second - season corn in Brazil in the 2024/2025 season has ended, 2 percentage points higher than the 98% a week ago, and the harvesting was also completed in the same period last year [2]. - Pro Farmer's final yield forecast shows that the total US corn production in 2025 is expected to reach 1.6204 billion bushels, with an average yield of 182.7 bushels per acre, which is lower than the USDA's August forecast [2]. 3.9 Key Points to Watch - Monitor the weekly corn consumption data from Mysteel and the operating rate and inventory of starch enterprises on Thursday and Friday [3].

Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Views - Corn: In the domestic market, the continuous auction of imported corn in the main producing areas and the listing of spring corn have increased supply. Trade entities are less willing to hold prices and more eager to clear inventories. With weak downstream demand, the market's confidence in price increases has diminished, and corn prices are gradually bottoming out. The corn market remains in a weak trend, and a bearish approach is recommended [2]. - Corn Starch: As previously shut - down enterprises resume operations, supply pressure has increased. With downstream demand in the off - season and poor sales, the supply of corn starch far exceeds demand. Corn starch inventory has increased, and the market remains in a weak trend, suggesting a bearish approach [3]. 3.

Report Industry Investment Rating - No information provided on the report industry investment rating Core Viewpoints - For the corn market, the USDA's August supply - demand report is overall bearish, causing international corn prices to decline. In the domestic market, factors such as continuous auctions of imported corn in the Northeast, the release of old - stock corn, good growth of new - season corn, and weak market sentiment lead to a weak trend in the corn market, suggesting a bearish approach [2]. - For the corn starch market, with the resumption of operations of previously - overhauled enterprises, the industry's operating rate has increased, leading to greater supply pressure. Meanwhile, downstream demand is in the off - season, resulting in a clear oversupply situation. The market shows a weak trend, and a bearish approach is recommended [3].
