Group 1 - Since mid-October, corn futures prices in Dalian have reversed the downward trend observed since late September, beginning to rise slightly due to continuous rain in North China and increasing expectations of reduced corn production [1] - The prolonged rainy weather in North China's main corn-producing areas has led to record-breaking rainfall, resulting in increased moldy corn and a sharp decline in high-quality corn, thereby reducing effective supply [1] - The reliance of feed enterprises on Northeast corn is expected to increase, which will support the overall rise in domestic corn prices [1] Group 2 - Due to trade frictions, China's total corn imports have significantly decreased, with September imports of corn and corn flour at 60,000 tons, an 81.9% decrease year-on-year [2] - From January to September, cumulative corn imports were 930,000 tons, down 92.7% compared to the same period last year [2] - The demand for corn deep processing has declined due to reduced processing profits, with an estimated consumption of 5.1 million tons in September, a decrease of 48,000 tons year-on-year [2] Group 3 - Despite the decrease in deep processing demand, the steady growth in feed demand can partially offset this pressure, indicating a shift in the market supply-demand balance from a previous surplus to a tight equilibrium [2]

Report Information - Report Name: Nanhua Futures Corn & Starch Industry Daily Report - Date: October 21, 2025 - Analyst: Dai Hongxu (Investment Consulting License No.: Z0021819) - Research Assistant: Kang Quangui (Qualification Certificate No.: F03148699) - Investment Consulting Business Qualification: CSRC License [2011] No. 1290 [1] Industry Investment Rating - Not provided in the report Core Views - On Monday, the corn futures market generally closed higher, with far - month contracts leading the rise. The futures price started to recover from the September decline, showing a near - weak and far - strong pattern. The corn 01 - 05 spread broke through - 100 yuan/ton, hitting a record low, indicating an optimistic market expectation for the 2026 corn price, which may limit the downside price space [2]. - In the spot market, although the current supply pressure still exists, after more than half a month of price decline, the new - season pressure has been released. With the purchase by some Sinograin depots, the spot price has stabilized, suggesting that the first - round price shock is over. The futures price may enter a bottom - grinding stage, and whether it will have a second bottom - probing depends on the corn market performance in the second half of October. The period from late October to early November may confirm the price bottom. It is recommended to focus on whether the 2601 contract can hold the 2100 - yuan level [2]. - Corn starch mainly followed the corn price rebound, showing no independent strength and still weaker than the raw - material side [2]. - On Monday, CBOT corn futures rose for the fifth consecutive trading day but with a small increase, mainly following the soybean price increase, and the high - yield pressure restricted the upward trend [2]. Summary by Related Content Market Performance - **Spot Market**: In the corn spot market, prices in some regions increased, such as in Jinzhou Port (up 30 yuan to 2180 yuan), Harbin (up 20 yuan to 2000 yuan). In the corn starch spot market, the price in Shandong increased by 20 yuan to 2750 yuan [4]. - **Futures Market**: Corn futures prices generally rose, with the corn 07 contract having the largest increase of 1.56% (up 35 yuan to 2272 yuan). Corn starch futures prices also increased, with the corn starch 03 contract rising by 1.16% (up 28 yuan to 2435 yuan) [4]. - **CBOT Market**: CBOT corn futures rose for five consecutive days, with the main - continuous contract price at 424, up 1 (0.24%). The main - continuous contracts of CBOT soybeans and wheat also increased [27]. Factors Affecting the Market - **Likely Positive Factors**: Some Sinograin depots are conducting supportive purchases and may increase the number of purchasing depots; the strong rebound of far - month futures contracts boosts market confidence; in September 2025, China's imports of corn and corn flour were 60,000 tons, a year - on - year decrease of 81.9%, and from January to September 2025, the cumulative imports were 930,000 tons, a year - on - year decrease of 92.7%; the National Food and Strategic Reserves Administration held a meeting to promote autumn - grain purchase and production - sales connection, emphasizing measures to maintain reasonable grain prices and protect farmers' interests [2][3]. - **Likely Negative Factors**: The pig industry is in the process of capacity adjustment, which may affect the long - term feed demand for corn; the release of new - season supply pressure still takes time, and the spot price remains under pressure [3]. Other Information - **Warehouse Receipts**: The number of registered corn warehouse receipts increased significantly by 12,615 to 49,324 [2]. - **Import Price and Profit**: The landed duty - paid price of US Gulf corn was 2119.1 yuan, up 6.07 (0.29%), with an import profit of 190.9 yuan; the landed duty - paid price of US West corn was 1965.97 yuan, up 0.95 (0.05%), with an import profit of 344.03 yuan [27].

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - The U.S. corn report lowered the yield per unit, but the production remains high. The U.S. corn price declined and may continue to fall in the future. China has imposed a 15% tariff on U.S. corn and a 22% tariff on U.S. sorghum. The import profit of foreign corn is high. The northern port corn prices have stabilized and rebounded, while the North China corn prices continue to decline. The domestic corn market is expected to be relatively stable in the short term, but there may be selling pressure in late October. The corn starch market is affected by the corn price and downstream inventory, and the short - term price is expected to fluctuate narrowly [4][5]. - For trading strategies, it is recommended to hold long positions in 01 or 05 corn contracts and set stop - profit levels, and to wait and see for arbitrage [7]. - For options, a short - term strategy of accumulating puts and calls with rolling operations is recommended [10]. Group 3: Summary by Directory First Part: Data - **Futures Market**: On October 16, 2025, most corn futures contracts rose, with C2601 up 0.42%, C2605 up 0.76%, and C2509 up 0.66%. Some corn starch futures contracts also showed different trends, with CS2601 down 0.04%, CS2605 up 0.47%, and CS2509 up 0.89%. The trading volume and open interest of each contract also changed to varying degrees [2]. - **Spot and Basis**: The spot prices of corn in different regions showed different trends, with prices in some ports stabilizing and rebounding, and prices in North China falling. The basis of corn and corn starch also showed different values in different regions. The price differences between different periods of corn and corn starch and between different varieties also changed [2]. Second Part: Market Judgment - **Corn**: The U.S. corn report lowered the yield per unit, but the production is still high, and the price may continue to decline. China's import tariffs on U.S. corn and sorghum have changed. The northern port prices have stabilized and rebounded, and the North China prices continue to fall. The domestic corn market is expected to be relatively stable in the short term, but there may be selling pressure in late October [4][5]. - **Starch**: The number of trucks arriving at Shandong deep - processing plants has increased, and the corn and starch prices in Shandong and Northeast China are weak. The inventory of corn starch has increased. The price of starch depends on the corn price and downstream inventory. The short - term price is expected to fluctuate narrowly [6]. Third Part: Corn Options - The recommended option strategy is a short - term strategy of accumulating puts and calls with rolling operations [10]. Fourth Part: Related Attachments - The attachments include various charts showing the spot prices of corn in different regions, the basis and price differences of corn and corn starch futures contracts, which help to analyze the market trends of corn and corn starch [12][14][18].

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - The corn market this year is expected to be relatively stable with limited price fluctuations. The lower bound of the price range is supported by planting costs and farmers' selling sentiment, while the upper bound is determined by downstream inventory - building sentiment, grain substitution scale, and policy - related grain auction rhythm and intensity. In the short term, the price is expected to be weak before November; in the medium term, the decline is limited; in the long term, the upward potential is also limited [8][9] - The corn industry chain has a higher acceptance and more proficient use of corn futures and derivatives for risk management [10][11][12] - For corn futures, the short - term logic is about new - grain supply pressure and cost support; the medium - term is about new - season drivers and wide - range trading; the long - term is about import substitution and policy orientation. The trading strategy is to maintain a medium - and long - term range - trading approach and pay attention to low - buying opportunities [13][14] Group 3: Summary by Directory 1. New and Old Corn Alternation: Focus on New - Season Corn - New - season corn in Heilongjiang is expected to have a stable and increasing yield this year, with an increase in single - yield and better quality compared to last year [4] - The corn planting cost in Heilongjiang has decreased this year, mainly due to the decline in land rent. The estimated new - grain planting cost at the port is about 2100 - 2150 yuan/ton [5] - The opening price of new - season corn in Heilongjiang has shown a high - opening and low - going trend. The market sentiment is cautious, and downstream enterprises are in a passive inventory - building stage. Some farmers will start to hold back if the price is too low [7] 2. Current Situation and Outlook of the Corn Market - The corn market price has shown a trend of rising first and then falling this year, with a wide - range operation. The international supply is under pressure, but the impact of imports on the domestic market is small. Domestic new - season corn is expected to be abundant, and the supply - demand gap depends on wheat substitution and policy - related grain sources. The demand from the breeding and deep - processing industries is weak [8] - The future corn market is expected to be relatively stable, with price fluctuations mainly affected by factors such as planting costs, farmers' selling sentiment, downstream inventory - building, grain substitution, and policy - related grain auctions [9] 3. Participation of Enterprises in Corn Futures and Derivatives - The corn industry chain has a high recognition of the price - discovery and hedging functions of corn futures. Enterprises use pricing models such as basis + fixed price, and the acceptance and use of basis pricing are relatively common [10][11] - All links in the corn industry chain have improved their acceptance and proficiency in using corn futures and derivatives for risk management, such as upstream farmers using hedging and insurance + futures, and downstream enterprises using selling hedging [11][12] 4. Corn Futures Views and Operation Suggestions - The short - term market logic is about new - grain supply pressure and the impact of bad weather in North China. The medium - term is about new - season drivers, and the long - term is about import substitution and policy orientation [13] - The trading strategy is to maintain a medium - and long - term range - trading approach, pay attention to low - buying opportunities around 2100 and below for the 2601 contract, and hold long positions lightly. The first pressure level is 2140, and the second is 2150 [14]

Core Insights - The corn market in China is transitioning as the new harvest season begins, with key focus on production estimates, farmer selling sentiment, and downstream inventory building [2] Production and Yield - Corn yield in Heilongjiang is expected to increase year-on-year despite a slight decrease in planting area due to favorable weather conditions, with yields ranging from 12 to 13 tons per hectare, and some areas achieving up to 20 tons per hectare [3] - The quality of the new corn crop is reported to be better than last year, with specific gravity levels between 710-750 g/L [3] Cost of Production - The cost of corn production in Heilongjiang has decreased, primarily due to lower land rental costs, with average land rent around 12,000 RMB per hectare compared to 13,000 RMB last year [4] - Total planting costs are estimated between 17,000 to 21,000 RMB per hectare, with a calculated cost of approximately 1,500 RMB per ton for 30% moisture corn [4] Market Sentiment - Market sentiment is cautious, with new corn prices starting high but declining due to strong harvest expectations and limited inventory building by processing companies [6][5] - Farmers are willing to hold onto their corn if prices fall below 0.8 RMB per jin, indicating a focus on price support levels [6] Market Outlook - The corn market is expected to remain stable with limited price fluctuations, influenced by planting costs, farmer selling sentiment, and inventory building by downstream enterprises [8] - The price range for corn at Jinzhou Port has been between 2,000 to 2,400 RMB per ton, with a recent price of 2,310 RMB per ton [7] Derivatives Market Participation - Participation in the corn futures market has increased, with industry players recognizing the importance of futures for price discovery and risk management [9] - The use of basis pricing and hedging strategies is becoming more common among traders and processing companies, with basis pricing accounting for 30% to 50% of transactions [9][10] - The "Silver Futures" project has provided financial support to farmers, enhancing their ability to manage risks and secure sales post-harvest [10]

Based on the fourth - quarter forecast range, the price has taken an important step in bottom - finding. The price structure shows near - term weakness and long - term strength, corresponding to the decreasing pressure of spot supply. The 2601 contract is about to become the main contract, and the futures price regained 2,100 yuan yesterday. It may form a short - term consolidation and repair, and the opening of storage warehouses to purchase supports the rebound of the futures price. The registered warehouse receipts have slightly increased to 36,709 lots. [2] - In the spot market, the market continues to digest the pressure of new grain listing, and the spot price is weak. The purchase prices of deep - processing enterprises in Shandong and North China have more declines than increases. There are positive changes in the Heilongjiang production area, where some direct - affiliated warehouses of the China Grain Reserves Corporation have started to purchase corn, which stabilizes the price. With the start of purchases by the China Grain Reserves Corporation, the decline of the corn spot price may change rhythmically, and the recent large decline needs to be repaired. The positive factors in the market are accumulating, but during the period of new grain supply, the support is insufficient, and the market will mainly digest the pressure in the short term. By the end of this month, the new grain harvesting will enter the final stage, and important price nodes may appear. [2] - The CBOT corn futures price is running weakly, waiting for further guidance from the US Department of Agriculture's October supply - demand report. Due to the government shutdown, the report release time has been postponed.

The wheat average price remained unchanged. [4][7] Factors Affecting the Market - **Likely Positive Factors**: The purchase by direct - affiliated warehouses of the China Grain Reserves Corporation restricts the price decline space; relevant national departments have intensively investigated the North China and Huang - Huaihai production areas and taken multiple measures to relieve the impact of rainfall on the harvest and listing of crops; the pressure of domestic corn production increase is limited, and it is expected to show resilience after the seasonal pressure. [2] - **Likely Negative Factors**: The pig industry is in the process of capacity regulation, which may affect the medium - term demand for corn for feed; the release of the new - season supply pressure still takes time, and the price is in the process of bottom - finding or at the bottom; there are many trucks arriving in Shandong, and deep - processing enterprises generally purchase at reduced prices; the deteriorated corn in North China still impacts the price.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - In the fourth quarter, it is the period of concentrated supply of new-season corn. In October, the pressure of harvest and concentrated listing is relatively large. The supply-demand structure is temporarily imbalanced, leading to a situation where prices are more likely to fall than rise. The price of new-season corn has been declining. Since October, continuous rainy weather in the North China production area has led to a decline in corn quality, adding additional short-term price pressure. The production situation in the Northeast production area is good, with mainly sunny weather. After continuous declines, prices have recently stopped falling, mainly due to the excessive short-term decline. The maximum decline in the price of damp grain has exceeded 150 yuan/ton. Additionally, the decrease in the proportion of high-quality corn in the North China production area provides some support for the Northeast production area. Local deep-processing enterprises in the Northeast may initiate grain-locking actions, helping prices to stop falling. Overall, although not pessimistic about the medium- to long-term corn prices, currently it is still the peak period of new-season corn listing, and prices are still under pressure. Bullish factors need to accumulate and ferment, and it is difficult to say that prices will stabilize and rise in the short term. Attention should be paid to the price performance at the end of the month and early November [1]. - The corn futures on the Dalian Commodity Exchange took an important step in the bottom-finding process yesterday. Multiple contracts declined simultaneously. The main November contract fell below the 2,100-yuan mark, becoming the first corn contract this year to break through this level. The decline in far-month contracts weakened successively, and the month-spread structure steepened. The number of registered warehouse receipts increased significantly, highlighting the pressure on the spot market [1]. - The price of CBOT corn futures is consolidating at a low level, waiting for further guidance from the USDA's October supply and demand report [1]. Summary by Relevant Catalogs Bullish Factors - The import volume of corn and grains remains at a low level, providing a basis for the improvement of the medium-term corn supply-demand structure [5]. - The pressure of domestic corn production increase is limited, and it is expected to show resilience after the seasonal pressure passes [5]. - The purchasing sentiment in the Northeast production area has increased, and prices have stopped falling [5]. Bearish Factors - The pig industry is in the process of production capacity regulation, which may affect the medium-term feed demand for corn [3]. - The release of the new-season supply pressure still needs a process, and prices are in the bottom-finding or bottom-grinding stage [3]. - In the past two days, there have been many trucks arriving in Shandong, and deep-processing enterprises generally purchase at reduced prices [3].

Report Industry Investment Rating - Not provided in the content Core Viewpoints - The report suggests maintaining a bearish outlook for the medium to long term in the corn and corn starch markets. For corn, with the progress of the US corn harvest, supply pressure will gradually increase, and domestic new - corn harvest in the Northeast is accelerating, leading to a weakening of both US and domestic corn prices. For corn starch, increased supply of raw material corn, reduced downstream demand, high inventory, and substitution from other starches are causing the market to decline in tandem with corn [8][11][12] Summary by Directory 1. Week - to - Week Summary Corn - **Market Review**: The main 2511 contract of corn futures closed at 2125 yuan/ton, down 18 yuan/ton from before the holiday [8] - **Market Outlook**: US corn inventory as of September 1 was higher than expected, and the harvest progress was about 29%. In China, the new - corn harvest in the Northeast is accelerating, with high selling enthusiasm among farmers and limited capacity of grain - using enterprises, resulting in price cuts. The futures price is weakly adjusted under the influence of weak spot prices [8] - **Strategy**: Maintain a bearish outlook in the medium to long term [7][11] Corn Starch - **Market Review**: The main 2511 contract of Dalian corn starch futures closed at 2432 yuan/ton, down 36 yuan/ton from before the holiday [12] - **Market Outlook**: With the increase in new - season corn supply, the cost support for corn starch weakens. Downstream demand has decreased, inventory is high, and substitution from other starches exists, causing the starch market to decline along with corn [12] - **Strategy**: Maintain a bearish outlook in the medium to long term [7][11] 2.

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - The overall corn production in Heilongjiang this year is slightly higher than last year but lower than 2023. The grain quality is better, especially with a high bulk density. The new - grain price is still weak. [13][12] - In the short - term (before November), the corn market is bearish; in the medium - term, the downside is limited, and there is a strong willingness to build inventories at 1900 - 1950 yuan/ton after drying. In the long - term, the upside is not optimistic due to the pending release of policy grain sources. Overall, the corn price is expected to be relatively stable, and policy guidance is crucial.

Summary by Related Catalogs New Season Production Situation - **Sown Area**: The overall sown area in Heilongjiang decreased slightly year - on - year, with a 4% decline in the eastern region and some local areas having stable or increased areas. [14] - **Yield per Unit**: Excluding a small number of drought - affected plots, most areas saw an increase in yield per unit. In eastern Heilongjiang, the yield per unit was mostly 12 - 13 tons/ha this year, compared to 11 - 12 tons/ha last year. [14] - **Grain Quality**: The overall grain quality is better than last year, with a high bulk density (generally 710 - 720), and in Baoquanling, the bulk density is 740 - 750 with low toxin levels. [12] - **Production**: Slightly higher than last year but lower than 2023. [13] - **Planting Cost**: In eastern Heilongjiang, the average land rent this year is 12,000 yuan/ha, down from 13,000 yuan/ha last year. The total cost is about 18,000 yuan/ha, corresponding to a wet - grain price of 0.6 - 0.75 yuan/jin and a dried - grain price of 1520 - 1900 yuan/ton. [16] - **Opening Price**: The opening price of processing enterprises showed a high - to - low trend.

[24] - **Profit and Development Direction of the Processing Industry**: The processing profit of the corn deep - processing industry has been poor this year, with starch processing at a near - break - even point and alcohol in continuous loss. The future development direction is to vertically expand the industrial chain, especially focusing on amino - acid products. [25] - **Inventory - Building Plan and Rhythm**: Short - term, passive inventory building; medium - term, increase inventory building when the price approaches the planting cost. Traders are more positive, while enterprises are more cautious and focus on the impact of storage policies. [26] - **Actual Use of Futures**: The corn basis - point pricing model is widely used but needs improvement. Corn delivery warehouses are more proficient in using futures tools, and large enterprises are exploring hedging services. Currently, the corn futures price is at a discount to the spot price, and participation will resume when the market provides an opportunity. [27] Research Thinking - **Macro - Level**: Focus on policy - regulation directions and intensities, such as policy storage, policy - grain auctions, and import policies. [29] - **Industry - Level**: Consider the transmission of industrial profits, inventory cycles (passive inventory building), and expectations, behaviors, and results. [29] - **Supply - Demand Rhythm**: Pay attention to the rhythm of grain selling, inventory building, port collection, and futures - spot trading. [30]
