Report Industry Investment Rating - Not mentioned in the provided content Core Viewpoints of the Report - In September, the supply pressure of domestic polyethylene remained, with total production increasing year-on-year and decreasing month-on-month, and LLDPE showing double growth. The inventory was differentiated between upstream and downstream, with production enterprise inventory expanding and social inventory decreasing but with slow digestion. Import prices were differentiated, the quantity decreased, and the profit margins varied greatly. Downstream demand recovered less than expected, cost support was limited, and profits were under pressure. The market was dominated by supply and demand [4]. - In October, the supply pressure of domestic polyethylene is expected to increase, while demand may experience moderate growth with limited increase due to macro - economic uncertainties. The inventory pressure may ease from mid - to late October, and the market is likely to show a weak and volatile trend, and the specific trend depends on downstream demand release and new capacity commissioning progress [5]. Summary by Relevant Catalogs Supply Side - **Supply Pressure in September and October**: In September, the total domestic polyethylene production increased year - on - year but decreased month - on - month, with LLDPE showing double growth. The total production in September was 270,648 tons, a decrease of 12,067 tons from the previous month and an increase of 41,672 tons from the same period last year. LLDPE production in September was 125,520 tons, an increase of 653 tons from the previous month and 27,387 tons from the same period last year. In October, the supply pressure is expected to increase due to fewer planned maintenance of devices, restart of previously maintained devices, and new capacity commissioning [7][9]. - **Inventory Situation**: In late September, the inventory of polyethylene production enterprises increased, with the total reaching 458,300 tons, a month - on - month increase of 31,300 tons. The inventory of coal - based enterprises was 68,300 tons, and that of two - oil enterprises was 390,000 tons. The social inventory decreased, with the total at 534,800 tons, a month - on - month decrease of 27,200 tons. It is expected that the inventory pressure may ease from mid - to late October [12][13][14]. - **Import Situation**: In September, the import prices of polyethylene were regionally differentiated, with most major regions' LLDPE prices falling month - on - month. The import quantity continued to decline, with the import volume in August being 950,150 tons, a month - on - month decrease of 156,900 tons. The import profit margins of different varieties varied significantly [16][17][18]. Demand Side - **Demand in September**: In September, the overall downstream开工率 of polyethylene was 42.57%, a month - on - month increase of 2.85%. The raw material inventory of downstream enterprises increased, indicating increased raw material stocking willingness. However, the overall demand intensity did not meet expectations, and the market was in a weak balance [21][22]. - **Demand Outlook in October**: In October, the demand is in the traditional peak season with release potential, such as increased demand for packaging films due to Double Eleven and for agricultural films due to cooling in the north. But due to macro - economic uncertainties, downstream enterprises are cautious, and demand is expected to grow moderately with limited increase [5][23]. Cost and Profit - **Cost**: In September, the cost of oil - based polyethylene decreased month - on - month to 7,548.04 yuan/ton, a decrease of 15.64 yuan/ton. The cost of coal - based polyethylene increased slightly to 6,410.8 yuan/ton, an increase of 75.19 yuan/ton [26][27]. - **Profit**: In September, the profits of both oil - based and coal - based polyethylene production enterprises declined. The profit of oil - based enterprises was - 289.11 yuan/ton, a month - on - month decrease of 14.71 yuan/ton, and the profit of coal - based enterprises was 764.53 yuan/ton, a month - on - month decrease of 15.25 yuan/ton [28]. - **Price Difference**: In September, the price difference between polyethylene and related varieties was differentiated. The average price difference between PE - PVC:01 contract was 2,298.82 yuan/ton, a month - on - month increase of 12.44 yuan/ton, while the average price difference between PE - PP:01 contract was 275.23 yuan/ton, a month - on - month decrease of 15.25 yuan/ton [29]. Summary - In September, the domestic polyethylene market was in a weak balance.

The market was mainly dominated by supply and demand [32].

1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views Copper - The preliminary consensus between China and the US boosts market optimism, and copper prices hit a new high this year. In the short - term, the negotiation rhythm will drive trading. The 9 - month CPI further consolidates the expectation of interest rate cuts in October, with 2 possible cuts this year and the Fed stopping balance - sheet reduction. - Tight copper ore supply supports the price bottom. If by - product prices like sulfuric acid continue to fall and TC remains low, smelters may cut production. Downstream demand has strong resilience. In the long - term, supply - demand contradictions support the upward movement of copper prices, while short - term rapid increases may suppress demand. The main contract should focus on the support around 86,000 yuan/ton [1]. Aluminum - Alumina futures prices rebounded slightly, and spot market trading became more active. Supply pressure is significant due to high domestic operating capacity and an open import window. Demand is weak, and the full - caliber inventory increased by 64,000 tons last week. With the end of the rainy season in Guinea, cost support from the ore end is weakening. Short - term alumina prices will be under pressure, with the main contract oscillating between 2,750 - 2,950 yuan/ton [3]. - Aluminum prices were strong, breaking through 21,300 yuan/ton. The macro - environment is mixed, and the fundamentals are in a tight - balance. Supply of ingots is restricted by the high direct - supply ratio of molten aluminum, and demand shows resilience in the peak season. Aluminum ingot inventory increased by 1,000 tons to 626,000 tons on October 28. Short - term Shanghai aluminum will maintain a strong oscillation, with the main contract in the range of 20,800 - 21,400 yuan/ton [3]. Aluminum Alloy - Casting aluminum alloy prices oscillated strongly, with cost support becoming more prominent. Tight scrap aluminum supply pushed up procurement costs, and the refined - scrap price difference narrowed. The supply - demand is in a tight - balance. Supply is restricted by raw - material circulation and policy uncertainty, and demand shows stable resilience. Inventory is decreasing. Short - term ADC12 prices will maintain a strong oscillation, with the main contract in the range of 20,300 - 20,900 yuan/ton [4]. Zinc - The preliminary consensus between China and the US warms the macro - atmosphere, and zinc prices oscillated strongly. The supply - side logic of loose supply has spread from zinc ore to zinc ingots, and subsequent supply growth may be limited due to compressed smelting profits. Demand is stable, and there is a risk of a short squeeze in LME zinc, supporting zinc prices. The export window for zinc ingots is intermittently open. Short - term zinc prices have support at the bottom, but the fundamentals have limited elasticity for continuous upward movement. The main contract should refer to 21,800 - 22,800 yuan/ton [8]. Tin - Tin ore supply is tight, and processing fees remain low. In September, domestic tin ore imports decreased month - on - month. The change in Myanmar's tax method is expected to limit the improvement of tin ore supply this year. Demand is still weak, and although AI and the photovoltaic industry drive some consumption, it cannot make up for the decline in traditional consumption. Tin prices will oscillate strongly, and the follow - up depends on macro - changes and Myanmar's supply recovery [10]. Nickel - The Shanghai nickel market oscillated, and refined nickel prices rose slightly. Overseas, the expectation of Fed interest rate cuts is rising; domestically, the 14th Five - Year Plan brings policy expectations. Refined nickel production remains high. Ore prices are firm, but nickel - iron prices are under pressure, and industry profits are shrinking. Stainless steel demand is weak, while downstream ternary materials still have restocking needs. Inventory is accumulating. Short - term prices will oscillate, with the main contract in the range of 120,000 - 128,000 yuan/ton [12]. Stainless Steel - The stainless - steel market oscillated narrowly, and spot prices were slightly adjusted down. Overseas, the expectation of Fed interest rate cuts is rising; domestically, policies are mainly for stability. Nickel ore prices are firm, but nickel - iron prices are under pressure, and chromium - iron markets are weak. Supply pressure will increase in October, and demand improvement is not obvious. Social inventory is decreasing slowly. Short - term prices will oscillate weakly, with the main contract in the range of 12,500 - 13,000 yuan/ton [14]. Lithium Carbonate - Lithium carbonate futures were strong, with the main contract LC2601 rising 2.53% to 81,900 yuan/ton. After entering the peak season, there is a supply - demand gap, which is expected to widen in October. Production is increasing, mainly from new salt - lake projects and increased lithium - spodumene subcontracting. Downstream demand is optimistic, and raw - material inventory is decreasing. Short - term prices will run strongly, with the upper limit first observing the capital performance around 82,000 - 83,000 yuan/ton, and then 85,000 yuan/ton if it breaks through [16]. 3.

Industry Overview - The capacity utilization rate of PVC production enterprises decreased to 76.57%, down 0.12% week-on-week and 0.67% year-on-year. The calcium carbide method utilization was at 74.38%, down 0.34% week-on-week and 1.91% year-on-year, while the ethylene method increased to 81.64%, up 0.38% week-on-week and 1.68% year-on-year [1] - The maintenance loss for PVC production last week was 80,500 tons, an increase of 1,600 tons compared to the previous period [1] - The current PVC industry inventory stands at 1.4249 million tons, showing a slight decrease from last week. The overall inventory (upstream + social) decreased by 1.47% week-on-week [1] Institutional Insights - Zhengxin Futures noted that with maintenance gradually recovering and high absolute inventory levels, the fundamental support is insufficient. However, prices are at relatively low levels, and domestic policy expectations suggest that PVC will mainly experience low-level fluctuations in the short term [2] - Guotou Anxin Futures observed that while pressure from manufacturers and society has decreased, the overall situation remains under high pressure. Production has slightly declined due to maintenance, and domestic demand is stable. Export activities in September continued to show positive trends. Recent stability in calcium carbide prices has not significantly supported costs, indicating a continuation of a weak market environment, with PVC likely operating within a bottom range due to potential policy pressures on exports [3]

1. Report Industry Investment Rating No information provided regarding the report industry investment rating. 2. Core Views of the Report - PTA: With cost support and peak - season restocking, PTA inventory reduction continues. It is expected to have a short - term strong - side oscillation at a low valuation. However, the long - term supply - demand situation is weakening, and the rebound momentum is limited. Attention should be paid to crude oil dynamics [6]. - MEG: The cost side of ethylene glycol performs well. With some device maintenance and blocked arrival of imported goods, it is expected to continue the short - term rebound trend [6]. 3. Summary According to the Directory 3.1 Upstream Industry Chain Analysis - **Price and Market Trend**: Due to the US increasing sanctions on Russia, the ongoing stalemate in the Russia - Ukraine conflict, and the easing of market concerns about trade disputes, combined with the decline in US commercial crude oil inventories, international crude oil rebounded from a low level. For PX, with cost support, many factories reported reduced reform loads or malfunctions, and terminal restocking enthusiasm increased, leading to a recovery in the absolute price of PX. As of October 24, the closing price of Asian PX was $815/ton CFR China, up $32/ton from October 17 [16]. - **Capacity Utilization**: The 1 million - ton device of Urumqi Petrochemical continued maintenance and was planned to restart around October 29; two 1.4 - million - ton devices of Fushun Dahua continued maintenance and were planned to restart in early November. The weekly average capacity utilization rate of PX was 86.33%, a decrease of 1.09% compared to the previous week [19]. - **Price Difference**: As of October 24, the PX - naphtha price difference was $233.9/ton, a decrease of $12.3/ton from October 17. Although many factories reported reduced reform loads or malfunctions, the cost side was significantly driven up by crude oil, resulting in a narrow decline in the PX - naphtha price difference [22]. 3.2 PTA Fundamental Analysis - **Market Trend**: In the first half of the week, affected by the weakening of oil prices, the overall sentiment in the commodity market was low, and the pessimistic sentiment in the industrial chain spread. The spot price of PTA continued to weaken. In the middle of the week, as oil prices rebounded from a low level, the overall sentiment in the commodity market improved, and the purchasing enthusiasm of downstream industries in the traditional peak season increased. The spot price rebounded from a low level. As of October 24, the spot price of PTA was 4,450 yuan/ton, and the spot basis was 2601 - 81 [25]. - **Capacity Utilization**: The weekly average capacity utilization rate of PTA reached 75.98%, a month - on - month increase of 0.42%. Although the load of Yisheng Ningbo's device decreased, due to the load increase of Yisheng New Materials last week, the increase was more than the decrease, and the overall domestic production this period increased. In October, Ineos and Hengli both had maintenance plans, and the restart times of Yisheng Dalian and Yisheng Hainan were not yet determined. The monthly production of PTA may increase significantly. Attention should be paid to whether there will be more - than - expected production cuts in existing devices [28]. - **Processing Fee**: The terminal performance was mediocre, the purchasing enthusiasm of downstream industries was hindered, and the spot price trend was sluggish. However, the raw material supply was tight, and the price trend was strong. This week, the PTA processing fee continued to decline. Next week, there is an expectation of a rebound in the PTA spot price, but the maintenance devices have restart plans, and the polyester end changes little. The inventory reduction amplitude in the balance sheet narrows, and the PTA processing fee may be slightly repaired [31]. - **Supply - Demand Situation**: In October, there was insufficient PTA device maintenance, and the maintenance devices restarted one after another. With little change in demand, the PTA supply - demand situation is expected to be in a loose balance [32]. 3.3 MEG Fundamental Analysis - **Market Trend**: At the beginning of the week, the market continued to worry about the supply - demand pattern. In the middle of the week, affected by factors such as the continuous rise of crude oil, the reduction in supply, and the decrease in imported goods, the price of ethylene glycol rose from a low level. As of October 24, the closing price of ethylene glycol in Zhangjiagang reached 4,183 yuan/ton, and the delivered price in the South China market remained stable at 4,280 yuan/ton [37]. - **Capacity Utilization**: This week, the total domestic ethylene glycol capacity utilization rate was 68.26%, a month - on - month decrease of 0.79%. Among them, the capacity utilization rate of integrated devices was 67.12%, a month - on - month decrease of 1.81%; the capacity utilization rate of coal - based ethylene glycol was 70.18%, a month - on - month increase of 0.94%. In October, due to cautious import expectations, the inventory accumulation amplitude at ports was limited, but the domestic production increase expectation was obvious. Attention should be paid to the impact of unexpected device changes [38]. - **Inventory**: As of October 29, 2025, the total expected arrival volume of domestic ethylene glycol in East China was 127,000 tons. As of October 23, the total inventory of MEG in the main ports of East China was 483,000 tons, a decrease of 10,000 tons compared to October 16 [42][44]. - **Profit**: With the stable operation of newly invested domestic devices, the overall supply continued to increase. The terminal orders were mediocre, and the downstream polyester demand was lackluster. The trend of weakening supply - demand could not be reversed. The raw material prices fluctuated, and the sample profits of each ethylene glycol production process showed both increases and decreases. As of October 24, the profit of naphtha - based ethylene glycol was - $95.04/ton, up $13.85/ton from last week; the profit of coal - based ethylene glycol was - 610.44 yuan/ton, down 140.24 yuan/ton from last week [46]. 3.4 Downstream Demand - Side Analysis - **Polyester Capacity Utilization**: The weekly average capacity utilization rate of polyester was 87.53%, a month - on - month decrease of 0.25%. Some domestic polyester devices were shut down for maintenance during the week. Next week, the previously shut - down and maintained devices have no clear restart expectations, and the commissioning of new devices is postponed. It is expected that the domestic polyester production will decline slightly next week [51]. - **Capacity Utilization of Each Product**: This week, the weekly average capacity utilization rate of polyester filament was 91.04%, a decrease of 0.02% from the previous period. The weekly average capacity utilization rate of polyester staple fiber was 85.14%, a month - on - month decrease of 2.02%; among them, the average capacity utilization rate of conventional staple fiber was 88.77%, a month - on - month decrease of 2.67%. The Fujian Shanli plant shut down during the period. The capacity utilization rate of fiber - grade polyester chips was 85.04%, a month - on - month decrease of 0.08% [57]. - **Inventory**: Downstream industries carried out centralized restocking during the week, the overall sales of polyester increased, and the finished product inventory of factories decreased [58]. - **Cash Flow**: The polymerization cost increased, and polyester filament manufacturers sold products at discounted prices. The cash flow of most varieties was compressed [63]. - **Weaving Load**: As of October 23, the comprehensive operating rate of chemical fiber weaving in the Jiangsu and Zhejiang regions was 66.45%, an increase of 2.39% compared to the previous data. The average number of terminal weaving order days was 15.68 days, an increase of 0.88 days compared to last week. As the weather gets colder, the demand for domestic autumn and winter fabrics is good, and the inventory pressure of grey fabrics is relieved. However, the market lacks confidence in future orders, and raw materials are purchased on a rigid basis. It is expected that the operating rate will still face downward pressure in the future [64]. 3.5 Summary of Polyester Industry Chain Fundamentals - **Cost**: International crude oil rebounded from a low level, and the absolute price of PX recovered [68]. - **Supply**: The weekly average capacity utilization rate of PTA increased slightly, and the total domestic ethylene glycol capacity utilization rate decreased [68]. - **Demand**: The weekly average capacity utilization rate of polyester decreased slightly, and the weaving operating rate in the Jiangsu and Zhejiang regions increased [68]. - **Inventory**: The supply of PTA is expected to increase, and the near - term supply remains tight, while the long - term supply - demand inventory accumulation expectation is strong. The inventory of MEG in the main ports of East China decreased [68].
