1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints - Nickel prices have basically returned to the fundamental logic, with high inventories and an unchanged pattern of oversupply. It is expected that nickel prices will remain in a low - level oscillation. For stainless steel, the eleven - week consecutive decline in inventory has ended, and accumulation has begun. The peak season is lackluster, and downstream demand has not improved significantly. With weakening cost support at the raw material end, stainless steel prices are expected to maintain a bottom - oscillating trend [4][7]. 3. Summary by Related Catalogs Market Analysis of Nickel - **Price**: This week, the price of the main Shanghai nickel futures contract showed a weak oscillating pattern, closing at 121,380 yuan/ton, a slight drop of 120 yuan/ton from the opening price on Monday. The weekly price fluctuation range was 120,670 - 123,550 yuan/ton, with an amplitude of 2.39%. LME nickel prices slightly declined to 15,210 US dollars/ton, a decrease of 0.43%. In the spot market, the latest offer of Jinchuan nickel's premium over the SHFE 2510 contract remained unchanged from last week, while the real - time converted premium in the Shanghai area decreased by 300 yuan/ton compared to last week [1]. - **Macro**: At the beginning of the week, cautious remarks from Fed officials on the prospect of interest rate cuts strengthened the US dollar, and the unchanged LPR in China reduced market risk appetite. Subsequently, the central bank's liquidity injection and the increasing expectation of Fed rate cuts warmed up the sentiment in the base metals sector, but the strong US economic data caused a rebound in the US dollar and a retreat of funds [2]. - **Supply**: In the nickel ore market, Philippine mine quotes remained firm, and the new typhoon "Boloiyu" was expected to affect local mine shipments. In Indonesia, although the supply of nickel ore was loose, there were frequent disturbances. In terms of refined nickel, China's refined nickel output in August 2025 was 36,695 tons, a month - on - month increase of 1.50% and a year - on - year increase of 29.62% [2]. - **Consumption**: In August 2025, China's apparent consumption of refined nickel was 37,600 tons, a month - on - month increase of 25.66% and a year - on - year increase of 81.16%.

For example, the cost of integrated MHP production of electrowon nickel was 117,171 yuan/ton, with a profit of 3.20%, while the cost of externally purchased nickel sulfate production of electrowon nickel was 136,583 yuan/ton, with a profit of - 11.20% [3]. - **Inventory**: This week, SHFE nickel inventory decreased by 504 tons to 29,008 tons, LME nickel inventory decreased by 204 tons to 230,124 tons, and China's (including bonded areas) refined nickel inventory decreased by 1,371 tons to 40,440 tons [3]. Strategy for Nickel - Unilateral: None - Inter - delivery spread: None - Cross - variety: None - Futures - cash: Adopt the idea of selling hedging on rallies in the medium - to - long - term - Options: None [4] Market Analysis of Stainless Steel - **Price**: This week, the main stainless steel futures contract showed a weak oscillating pattern, closing at 12,840 yuan/ton, a rise of 65 yuan/ton from last week. The spot procurement sentiment was frustrated, and the pre - holiday procurement demand did not appear as expected [4]. - **Macro**: The central bank's liquidity injection boosted market risk appetite, but the Fed's internal differences after the rate cut and the approaching National Day holiday led to a decline in market trading activity [5]. - **Supply**: In August 2025, the output of stainless steel increased month - on - month. The output of the 200 - series increased by 8.97% month - on - month, the 300 - series increased by 2.44% month - on - month, and the 400 - series decreased by 0.5% month - on - month [5]. - **Consumption**: The traditional peak consumption season effect did not appear. Downstream terminals were cautious in purchasing. Although real - estate sales increased year - on - year, new construction areas decreased year - on - year, and the demand in the automotive retail sector declined [5]. - **Cost and Profit**: This week, the price of high - nickel ferro - nickel ended its continuous rise since July and slightly declined, while the price of high - carbon ferro - chrome slightly increased but lacked further upward momentum [6]. - **Inventory**: On September 26, the total social inventory of stainless steel in the mainstream markets across the country increased week - on - week, ending the eleven - week consecutive decline [6].

Report Industry Investment Rating - Not provided in the document Core Viewpoints - The fundamentals show that the comprehensive profit of enterprises has declined, the valuation pressure has decreased, the maintenance volume is low, and the production is at a historical high. In the short term, multiple new devices will be tested. On the downstream side, domestic operations have improved. Regarding exports, the anti - dumping tax rate in India has been determined, and exports are expected to weaken after implementation. The cost of calcium carbide has continued to rebound, while caustic soda has declined, leading to stronger overall valuation support. In the medium term, the industry is continuously suppressed by the significant increase in production capacity and the continuous decline in real - estate demand, and the industry pattern has deteriorated. It is necessary to rely on export growth or the implementation of policies to clear old devices to consume the excess domestic production capacity. Overall, given the current situation of strong supply and weak demand in China, with the weakening export outlook, even if the downstream has improved recently, it is still difficult to change the pattern of oversupply. The fundamentals are poor. In the short term, there will be a small rebound due to stronger valuation support, improved domestic demand, and a better commodity atmosphere. In the medium term, pay attention to short - selling opportunities on rallies [11] Summary by Directory 1. Weekly Assessment and Strategy Recommendation - **Cost and Profit**: The price of Wuhai calcium carbide is reported at 2,600 yuan/ton, a week - on - week increase of 200 yuan/ton; the price of Shandong calcium carbide is reported at 2,840 yuan/ton, a week - on - week increase of 60 yuan/ton; the price of medium - grade semi - coke in Shaanxi is 680 yuan/ton, a week - on - week increase of 20 yuan/ton. In terms of profit, the comprehensive profit of chlor - alkali integration has decreased, while the profit of ethylene - based production has increased slightly. Currently, the valuation support is neutral [11] - **Supply**: The PVC capacity utilization rate is 77%, a month - on - month decrease of 3%. Among them, the utilization rate of calcium carbide - based production is 76.9%, a month - on - month decrease of 2.5%; the utilization rate of ethylene - based production is 77.1%, a month - on - month decrease of 4.2%. Last week, the supply - side load decreased mainly due to the reduced loads of enterprises such as Shaanxi Beiyuan, Gansu Jinchuan, Zhongtai, Henan Yuhang, and Haohua. The load is expected to pick up slightly next week. The overall maintenance volume in September is expected to decline, and multiple devices are expected to be commissioned and put into production, further increasing the supply pressure [11] - **Demand**: Regarding exports, the final anti - dumping tax rate ruling result in India has been announced, and China's tax rate is at a significant disadvantage compared to other countries.

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports Polyolefin Industry - The market is in a state of "supply reduction and demand increase" with no obvious core contradictions. For PP, due to strong propylene and propane prices, PDH and external propylene procurement profits are suppressed, leading to more unplanned maintenance and inventory decline, but the basis is still weak due to new device commissioning. For PE, current maintenance remains at a relatively high level, resulting in low short - term supply pressure, rising basis, and inventory depletion. However, attention should be paid to the supply rhythm as maintenance volume may gradually decrease from mid - September. Current new orders for demand are poor, and attention should be paid to downstream replenishment before the Double Festival [2]. Crude Oil Industry - Overnight oil prices rose. The main trading logic is the market's concern about the interruption of refined oil and crude oil supply from Russia due to the escalation of geopolitical conflicts. The market's expectation of tight diesel supply has heated up, which may drive the crack spread to strengthen. At the macro level, the market expects the Fed to cut interest rates soon, and the weakening of the US dollar also provides additional upward momentum for oil prices. The current market trading focus has shifted from the easing expectation to the spot supply risk dominated by geopolitical factors, and the futures price is likely to run along the upper edge of the shock range in the short term. It is recommended to mainly wait and see on the single - side, with the upper pressure of WTI at [65, 66], Brent at [68, 69], and SC at [500, 510]. Wait for opportunities to expand the spread on the option side [4]. Chlor - Alkali Industry - For caustic soda, the futures price has stabilized and rebounded. From the supply side, there are maintenance plans in the northwest and northeast this week, and the operating rate is expected to decline. From the demand side, the main alumina enterprises have good receiving, but the alumina itself is in an oversupply pattern, and the price has shown a downward trend recently, and most alumina plants have sufficient raw material inventory days. The non - aluminum end demand has improved in the peak season, but the support for the caustic soda price is limited. Overall, the Shandong region has significantly accumulated inventory, but the main buyers have good willingness to receive, and the spot price may tend to be stable. Therefore, the downward space of the futures price may be limited. For PVC, the futures price has shown signs of stabilizing and stopping falling. On the supply side, there are many maintenance enterprises this week, and the output is expected to decline. On the demand side, the operating rate of downstream products has increased slightly, and some enterprises are preparing inventory for the National Day. The overall supply - demand pattern shows a marginal improvement trend. The supply tension of raw material calcium carbide has gradually eased, and the price has a narrow downward trend, while the ethylene price is weakly stable, and the cost side maintains bottom support [9]. Polyester Industry Chain - For p - xylene (PX), as domestic and foreign PX maintenance devices resume operation and short - process benefits are good, PX supply gradually increases to a relatively high level. Although the "Golden Nine and Silver Ten" expectation still exists, the polyester and terminal loads are slowly recovering, providing some short - term support for demand. However, the expectation for new orders and load peaks in the future is limited. The PX supply - demand is expected to be relatively loose in September, but the medium - term supply - demand is expected to be tight, and the price has support at the low level. This week, the PX price has shifted to November and December. Under the scenario of downstream demand transfer in the fourth quarter, the positive support for PX is limited. It is expected that PX will fluctuate strongly with the oil price in the short term, but the rebound space is limited. For PTA, the PTA supply - demand is expected to be tight in September as device maintenance is still concentrated. However, due to the good liquidity in the spot market and the sales of some mainstream suppliers, the overall spot basis is weak. The demand side has some support, but the basis and processing fee repair drive are limited under the weak medium - term supply - demand expectation, and the absolute price follows the raw material fluctuation. For ethylene glycol, the supply pattern is strong in the near term and weak in the long term. The import expectation is not high in September, and as it enters the peak demand season, the polyester load increases, and the rigid demand support improves, resulting in low port inventory and a strong basis. However, the supply - demand is expected to be weak in the fourth quarter due to new device commissioning and device restart, and ethylene glycol will enter the inventory accumulation channel, with the price under pressure. For short - fiber, the short - term supply - demand pattern is weak. The supply continues to increase, and although there is still the "Golden Nine and Silver Ten" expectation, new order follow - up is insufficient, and the peak season this year is not expected to be very prosperous. Currently, short - fiber factory inventory is low, and it has relatively strong support compared to raw materials. Overall, it mainly follows the raw material fluctuation. For bottle - grade polyester chips, in September, device restart and shutdown coexist, and supply increases slightly. Considering the decline in soft drink and catering demand as the weather turns cooler, demand may decline, and inventory is expected to increase slowly. The price mainly follows the cost side, and the processing fee has limited upward space [13]. Methanol Industry - In terms of supply and demand, the inland supply is at a high level year - on - year. Although unplanned maintenance has increased recently, some devices are expected to resume production in mid - September. With continuous external procurement by some olefin plants in the inland and unexpected maintenance, the inventory pattern is relatively healthy, which supports the price. The demand side is weak due to the off - season of traditional downstream industries. Some previously shut - down MTO plants at the port restarted last week, slightly relieving the port inventory pressure. In terms of valuation, the upstream profit is neutral, the MTO profit is marginally weakening, and the traditional downstream profit is still weak, with the overall valuation being neutral. The port is continuously accumulating a large amount of inventory, and the import volume remains high in September. The futures price fluctuates between trading the current high inventory and weak basis and the expectation of overseas gas restrictions in the future. Attention should be paid to the inventory inflection point [19]. Urea Industry - The futures price of urea has rebounded, mainly due to short - covering driving the improvement of low - end spot transactions, rather than the substantial improvement of supply and demand. Device restart has brought the daily output back above 190,000 tons, and there will be further increments in the future, so the supply pressure continues to accumulate. On the demand side, it is the off - season for agriculture, the industrial demand is rigid, and the export is marginally weakening. The fundamentals do not provide continuous upward momentum. This rebound is more of a result of capital game and sentiment repair, and the upward height is limited by the dual pressures of supply expansion and export profit contraction. Attention should be paid to the restart and maintenance implementation rhythm of devices such as Henan Xinlianxin and Shanxi Tianze [25]. Benzene - Styrene Industry - For pure benzene, due to the unplanned maintenance of a reforming device in East China, the supply in September is lower than expected. On the demand side, most downstream products are in a loss state, and some products' secondary downstream inventories are high. In addition, the maintenance plan of downstream styrene devices increases from September to October, so the demand - side support weakens. The supply - demand of pure benzene in September is still expected to be relatively loose, and the price driving force is weak. However, in the short term, with the strong oil price and the improvement of the domestic commodity macro - atmosphere, the price center of pure benzene is expected to be supported. For styrene, the overall operating rate of downstream 3S has declined. Some styrene devices are under planned maintenance, and some have reduced their loads due to accidents, resulting in a continuous decline in the high - level port inventory. With the short - term strong oil price, the driving force of styrene is expected to strengthen, but the rebound space is still limited by the high port inventory [30]. 3. Summaries According to Relevant Catalogs Polyolefin Industry - **Price Changes**: The closing prices of L2601, L2509, PP2601, and PP2509 all increased, with increases of 0.88%, 3.11%, 0.77%, and 2.65% respectively.

The market's expectation of tight diesel supply heated up, and the US pressured its allies to stop buying Russian oil, further amplifying the supply - side risk premium. At the macro level, the expected Fed interest rate cut and the weakening US dollar provided upward momentum for oil prices [4]. Chlor - Alkali Industry - **Price Changes**: The prices of Shandong 32% liquid caustic soda and SH2509 decreased, while the prices of East China calcium carbide - based PVC and V2509 increased significantly, with increases of 1.3% and 13.2% respectively [9]. - **Supply and Demand**: For caustic soda, the operating rate is expected to decline due to maintenance, and the demand from the alumina industry is good but the price is falling.
