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.

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.

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].

Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Views - For corn, international corn prices are under continuous pressure due to the high output prospects in the US, where the corn excellent - rate remains good and the weather is favorable for growth. In the domestic market, factors such as import corn reserve auctions, falling international grain prices, and lower new - season corn costs lead to a pessimistic outlook on forward corn prices. The spot price is weak, and the corn futures price is generally bearish [2]. - For corn starch, the supply - demand imbalance is obvious. The resumption of operations of previously - overhauled enterprises increases supply pressure, while downstream demand is in the off - season. The inventory has increased, and the starch futures price has been oscillating weakly at a low level, also suggesting a bearish view [4]. 3.

The excellent - rate of US corn is 73%, higher than the market expectation [2].

1. Report Industry Investment Rating - No relevant content provided 2. Core Views of the Report - For the corn market, the high-quality rate of US corn remains good, leading to continuous pressure on international corn prices. In the domestic market, the trade inventory in the Northeast production area has dropped to a low level, and the trading activity is poor with little price fluctuation. Wheat has substitution advantages, and import corn auctions and deferred pick - up policies restrict the corn market. The corn futures price has declined again due to the general decline of commodities and remains weak overall [2]. - For the corn starch market, due to continuous production losses, the industry's operating rate is at a low level in recent years, reducing supply pressure. However, downstream demand is in the traditional off - season, and the supply - demand situation remains loose. The corn starch futures price has been oscillating at a low level recently, and short - term observation is recommended [3]. 3.

1. Report Industry Investment Rating - No relevant content provided 2. Core Views of the Report - For corn, the international corn price is under continuous pressure due to the high output prospect as the good rate of US corn remains high. In the domestic market, the corn supply is tight with low remaining grain in the Northeast and low channel inventory. Traders are reluctant to sell at low prices. Although the transaction rate of imported grain auctions has slightly increased, the actual transaction volume is limited and the delivery speed is slow. However, the low processing profit and开机率 of deep - processing enterprises and the relatively safe inventory of feed enterprises limit the upward momentum of corn prices. The corn futures price has been fluctuating at a low level recently, and short - term observation is recommended [2]. - For corn starch, the industry's开机率 is at a low level in recent years due to continuous production losses, reducing supply pressure. But the demand in the civil and paper - making markets is poor, and it is the traditional off - season for downstream demand, so the supply - demand situation remains loose. The starch inventory has decreased slightly. The starch futures price has been fluctuating at a low level recently, and short - term observation is recommended [3]. 3.
