1. Report Industry Investment Rating The report does not provide an overall industry investment rating. However, for each specific energy and chemical product, the following ratings are given: - Crude oil: Oscillating [1] - Fuel oil: Oscillating [3] - Asphalt: Oscillating [3] - Polyester: Oscillating [5] - Rubber: Oscillating [7] - Methanol: Oscillating [8] - Polyolefins: Oscillating weakly [8] - Polyvinyl chloride (PVC): Oscillating [9] 2. Core Viewpoints of the Report - **Crude oil**: Geopolitical tensions have eased with the Israel - Hamas cease - fire agreement, leading to a decline in the geopolitical premium of crude oil and downward pressure on oil prices. US refinery operations and inventory data show an increase in commercial crude oil inventories and a decrease in gasoline and distillate inventories. Under the triple tests of supply increase expectations, geopolitical factor easing, and demand entering the off - season, oil prices are expected to continue their weakening trend [1]. - **Fuel oil**: Although the East - West arbitrage window for low - sulfur fuel oil is mostly closed, the inflow of component oils for blending low - sulfur fuel oil continues to increase. The Asian high - sulfur fuel oil market is relatively stable, but the supply may increase in the future. The high - sulfur fundamentals may be slightly stronger than the low - sulfur [3]. - **Asphalt**: During the National Day holiday, the overall supply of asphalt increased slightly. The continuous rainfall in the southern regions hinders downstream construction, while the northern regions still have some catch - up demand. The recent significant increase in asphalt production may put pressure on prices after the peak season [3]. - **Polyester**: In the fourth quarter, there will be some overseas PX device overhauls, and the ethylene glycol production capacity may continue to increase. The demand for winter fabrics has recovered seasonally but is expected to weaken in the second half of October. Under the situation of supply increase and demand weakening, the fundamentals of TA and ethylene glycol are weak, and their prices are expected to oscillate weakly [5]. - **Rubber**: Affected by Typhoon "Maideme", the rubber production in Hainan Island is expected to decrease. The US tariff on heavy - truck imports may suppress global rubber demand. After the holiday, rubber prices are expected to oscillate, and attention should be paid to new rubber warehouse receipts and crude oil price fluctuations [7]. - **Methanol**: The market is concerned about Iran's winter gas - rationing news. With the recovery of MTO device operations in East China, port demand has significantly increased, but MTO profit compression may affect refinery maintenance plans. In the short term, methanol prices are suppressed by high inventories and tend to oscillate [8]. - **Polyolefins**: Poor profit performance may lead to a high level of maintenance, and domestic production is unlikely to increase significantly in the short term. After the holiday, downstream orders will gradually decline, affecting the procurement of raw materials. Supply pressure remains high, demand has peaked and declined, and polyolefin prices are expected to oscillate weakly [8]. - **PVC**: In the fourth quarter, high - supply status will continue. As the peak season in October ends, downstream operations are expected to decline, and exports may weaken due to India's anti - dumping duties. High inventory pressure will restrict price increases, and market fluctuations may increase [9]. 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude oil**: On Thursday, the price of WTI November contract closed at $61.51 per barrel, down $1.04 or 1.66%. Brent December contract closed at $65.22 per barrel, down $1.03 or 1.55%. SC2511 closed at 464.2 yuan per barrel, down 4.5 yuan or 0.96%. Israel's approval of the Gaza cease - fire agreement led to a decline in the geopolitical premium. US refinery operations and inventory data show an increase in commercial crude oil inventories and a decrease in gasoline and distillate inventories [1]. - **Fuel oil**: On Thursday, the main contract of fuel oil (FU2601) on the Shanghai Futures Exchange closed down 1.25% at 2,834 yuan per ton, and the low - sulfur fuel oil main contract (LU2511) closed down 1.23% at 3,360 yuan per ton.

During the National Day holiday, the overall supply of asphalt increased slightly, and the southern rainfall affected downstream construction [3]. - **Polyester**: TA601 closed at 4,626 yuan per ton, up 1.54%. EG2601 closed at 4,234 yuan per ton, up 0.52%. In the fourth quarter, there will be some overseas PX device overhauls, and the ethylene glycol production capacity may increase. The demand for winter fabrics has recovered seasonally but is expected to weaken [5]. - **Rubber**: On Thursday, the main contract of Shanghai - traded rubber (RU2601) rose 95 yuan per ton to 15,620 yuan per ton. Affected by Typhoon "Maideme", rubber production in Hainan Island is expected to decrease, and the US tariff on heavy - truck imports may suppress demand [7]. - **Methanol**: On Thursday, the spot price in Taicang was 2,213 yuan per ton. The market is concerned about Iran's winter gas - rationing news. With the recovery of MTO device operations in East China, port demand has increased [8]. - **Polyolefins**: On Thursday, the mainstream price of East - China drawn polypropylene was 6,700 - 6,800 yuan per ton. Poor profit performance may lead to high - level maintenance, and domestic production is unlikely to increase significantly in the short term. After the holiday, downstream orders will decline [8]. - **PVC**: On Thursday, the price of PVC in the East - China market decreased. In the fourth quarter, high - supply status will continue, and downstream operations are expected to decline as the peak season ends [9]. 3.2 Daily Data Monitoring The report provides the spot price, futures price, basis, basis rate, and their changes for various energy and chemical products on October 10, 2025, including crude oil, liquefied petroleum gas, asphalt, high - sulfur fuel oil, low - sulfur fuel oil, methanol, urea, polyethylene, polypropylene, PTA, ethylene glycol, styrene, natural rubber, 20 - grade rubber, and soda ash [10]. 3.3 Market News - Israel and Hamas have reached a long - sought cease - fire and personnel release agreement, which weakens the geopolitical risk premium of crude oil and triggers investors to sell [12]. - In the absence of strong new signals in supply and demand, crude oil prices have also declined with the broader market. The US government shutdown and the strengthening of the US dollar have reduced the attractiveness of dollar - denominated commodities. Oil prices are likely to remain range - bound and slightly downward [12]. 3.4 Chart Analysis 3.4.1 Main Contract Prices The report presents the closing price trends of main contracts for various energy and chemical products from 2021 to 2025, including crude oil, fuel oil, low - sulfur fuel oil, asphalt, LPG, PTA, ethylene glycol, short - fiber, LLDPE, polypropylene, PVC, methanol, styrene, 20 - grade rubber, natural rubber, synthetic rubber, European container shipping, and p - xylene [14][17][20][21][23][25][27][28]. 3.4.2 Main Contract Basis The report shows the basis trends of main contracts for various energy and chemical products from 2021 to 2025, including crude oil, fuel oil, low - sulfur fuel oil, asphalt, ethylene glycol, PP, LLDPE, natural rubber, 20 - grade rubber, p - xylene, synthetic rubber, and bottle chips [31][35][36][39][42][44]. 3.4.3 Inter - period Contract Spreads The report displays the spreads between different contracts for various energy and chemical products, including fuel oil, asphalt, European container shipping index, PTA, ethylene glycol, PP, LLDPE, and natural rubber [46][48][51][54][58][60]. 3.4.4 Inter - variety Spreads The report presents the spreads and ratios between different varieties of energy and chemical products, including crude oil internal and external spreads, crude oil B - W spreads, fuel oil high - low sulfur spreads, fuel oil/asphalt ratio, BU/SC ratio, ethylene glycol - PTA spread, PP - LLDPE spread, and natural rubber - 20 - grade rubber spread [62][65][67][68]. 3.4.5 Production Profits The report shows the production profit trends of ethylene - based ethylene glycol, PP, and LLDPE from 2021 to 2025 [70][73]. 3.5 Team Member Introduction - **Zhong Meiyan**: Assistant to the director of the research institute and director of energy and chemicals, with over a decade of experience in futures and derivatives market research, has won multiple industry awards [77]. - **Du Bingqin**: Analyst for crude oil, natural gas, fuel oil, asphalt, and shipping, with in - depth research on the energy industry chain and has won many industry awards [78]. - **Di Yilin**: Analyst for natural rubber and polyester, with strong data analysis and logical thinking abilities, and has won several industry awards [79]. - **Peng Haibo**: Analyst for methanol, PE, PP, and PVC, with experience in integrating financial theory and industrial operations [80].

Report Overview 1. Report Industry Investment Rating No investment rating information is provided in the reports. 2. Report Core Views - **Polyolefins**: PE's current maintenance has reached a peak, and the start - up is gradually recovering. The inventory of the upper and middle reaches has decreased this week. Future attention should be paid to the supply rhythm and import offers. The pre - holiday CP settlement price has decreased, and the profit of PDH units has recovered. Attention should be paid to the return of PP units. In terms of demand, there are no bright spots, and there is significant inventory pressure after the holiday. Coupled with new capacity investment, the pressure of inventory accumulation in 01 is large, which limits the upside space [2]. - **Methanol**: The current market's core trading logic revolves around "high inventory + high imports". The port arrival volume remains consistently high, the inventory accumulation is significant, and the trading atmosphere has weakened, resulting in a downward price trend. The domestic supply is at a high level year - on - year. Although the number of unplanned maintenance units has increased recently, some units are expected to resume production in early October. The inventory pattern in the inland area is relatively healthy, providing some support for prices. The demand is weak due to the traditional off - season of downstream industries. In terms of valuation, the overall is in a neutral state. The current futures market is in a game situation, and future focus should be on the emergence of the inventory inflection point [5]. - **Polyester Industry Chain** - **PX**: The domestic PX load remains at a high level. The PTA processing fee is continuously low, new PTA device production is delayed, and multiple PTA units have maintenance plans. The PX supply - demand is expected to be weak in the fourth quarter, and there is an expectation of PXN compression. In the short term, PX has weak self - driving force, and the oil price support is limited. It is expected to fluctuate at a low level [8]. - **PTA**: The PTA supply is expected to shrink. The short - term downstream start - up remains at a relatively high level, and the PTA basis has been repaired, but the rebound space is limited under the weak expectation. In the short term, PTA has limited self - driving force, and the oil price support is limited. It is expected to fluctuate at a low level [8]. - **Ethylene Glycol**: After the National Day holiday, the port inventory has increased significantly. The domestic supply remains at a high level, and the supply - demand is gradually weakening. Therefore, the price of ethylene glycol is under pressure [8]. - **Short Fibers**: The short - fiber supply - demand pattern is weak. The supply remains at a high level, and the inventory pressure after the holiday is not significant. It is expected that the short - term support for short fibers is stronger than that of raw materials, but the driving force is limited, and the price will mainly follow the raw materials [8]. - **Bottle Chips**: In October, there is no news of further production cuts for bottle chips. The demand in the fourth quarter is in the traditional off - season. The demand side has limited support for bottle chips. It is expected that bottle chips will enter the seasonal inventory accumulation period, and the price will mainly follow the cost side [8]. - **Pure Benzene - Styrene**: The supply of pure benzene is expected to remain at a high level, and the demand growth has great uncertainty, with limited support. The supply - demand of pure benzene is expected to be loose, and the price driving force is weak. The supply of styrene is expected to increase, and the demand side support may be limited. The supply - demand of styrene is expected to be loose, and the price is under pressure after the holiday [9]. - **PVC - Caustic Soda** - **Caustic Soda**: The short - term demand for caustic soda lacks support and tends to be weak, and it can be treated bearishly in the short term. However, there is demand support in the medium and long term, and attention should be paid to the downstream restocking rhythm [10]. - **PVC**: The supply - demand contradiction of PVC is difficult to resolve. The supply is in an over - supply pattern, and the demand in the peak season is not strong. The cost side provides bottom support. It is expected that the downside space of PVC is limited during the peak season, and attention should be paid to the downstream demand performance [10]. 3.

Core Views - The chemical market shows complex trends with different product performances. Some products are affected by factors such as device maintenance, demand changes, and supply - demand imbalances [2][3][5]. - There are differences in the performance of the spot and futures markets, and the basis has changed in some products [2][3]. - The supply - demand relationship is a key factor affecting prices, with some products facing supply - demand contradictions [2][3][5] 3. Summary by Relevant Catalogs Olefins - Polyolefins - Propylene prices continued to rise due to early - started planned maintenance of a device in Dongying during the National Day holiday and the gradual recovery of some downstream demand. However, the futures price fell on the first trading day after the holiday, resulting in a divergence between the spot and futures markets and an enlarged basis [2]. - Polyolefins faced a situation of weak peak - season demand, mainly with rigid procurement. The large - scale release of new production capacity led to a significant increase in domestic output, resulting in prominent supply - demand contradictions. There was inventory accumulation during the holidays, and there was obvious pressure to reduce inventory after the holidays, causing price pressure [2] Pure Benzene - Styrene - During the National Day, the oil price dropped, and the pure benzene futures once fell below 5700 yuan/ton in the morning session and then rebounded with the oil price in the afternoon. The spot price in East China was weak, the shipment in Shandong was dull, and Sinopec's listed price remained stable. The device operation rate continued to rise, and the port inventory decreased. However, high imports and expected demand decline continued to drag down the market [3]. - The main contract of styrene futures closed slightly lower, with the overall center of gravity moving down along the 5 - day moving average. The oil price during the holiday was basically the same as before the holiday, having limited impact on the cost of styrene. The demand was weak during the peak season, and the supply increased significantly due to the expansion of production capacity. The inventory of styrene has been significantly higher year - on - year since this year and has shown a trend of oscillating inventory accumulation after June, suppressing the price [3] Polyester - During the holiday, the overseas oil price dropped, causing the prices of PX and PTA to weaken in the morning and then recover with the rebound of the oil price in the afternoon. The operation rate of PX continued to increase. Hengli Dalian's PTA carried out maintenance, and some East China devices reduced their loads due to reasons. In the short term, PX was under pressure, and the PTA link repaired its profit. However, in the future, the PX of Wushi Petrochemical plans to carry out maintenance, and the polyester load is expected to remain stable. The near - term supply - demand pattern of upstream raw materials is okay, and attention should be paid to terminal orders and raw material restocking. In mid - to late October, the downstream demand is expected to gradually weaken, and the supply - demand situation will still be under pressure in the long - term [5]. - The domestic operation rate of ethylene glycol increased significantly, and the port inventory accumulated significantly during the holiday, with a weak fundamental situation. The main futures price once approached the 4100 yuan/ton mark. In the medium - term, with the mass production of new devices and the weakening of future demand, the supply - demand situation will gradually weaken in the fourth quarter, and the 1 - 5 spread is under downward pressure [5]. - The new production capacity of short - fiber is limited, and the operation rate is at a high level. The terminal weaving and dyeing industries increased their operation rates, and the recovery of peak - season demand boosted the short - fiber industry. It is recommended to be long in the short - term, and attention should be paid to downstream orders and short - fiber inventory [5]. - The operation rate of bottle chips increased, but after the long holiday, with the cooling weather, the demand is expected to weaken. Overcapacity is a long - term pressure, and the processing margin is under continuous pressure [5] Coal Chemical Industry - The methanol futures price dropped significantly. During the holiday, the import volume remained high, and the port inventory continued to accumulate. The capacity utilization rate of domestic methanol devices increased. Before the holiday, inland olefin enterprises carried out centralized external procurement, and enterprises had sufficient pending orders, but the order execution was slowed down due to logistics restrictions, and the inventory of production enterprises increased slightly. Imports are expected to remain sufficient, and the port is expected to continue to accumulate inventory. The near - term situation is weak, while the far - month outlook is relatively strong. Attention should be paid to factors such as macro - sentiment and overseas device changes [6]. - During the National Day holiday, urea production enterprises significantly accumulated inventory, with high supply and great pressure on enterprise shipments. Affected by factors such as weather and logistics, the downstream demand was insufficient. Export orders were being shipped, and the port inventory decreased. Although India issued a new round of urea tenders, planning to import 2 million tons, the export window period may have ended, and the short - term boost to the market is limited. The pattern of loose domestic supply - demand of urea is difficult to change, and attention should be paid to possible policy adjustments and their impact on market sentiment [6] Chlor - Alkali Industry - The main contract of PVC dropped. During the holiday, the downstream demand weakened, the supply was at a high level, and the inventory increased significantly. After the end of maintenance and the release of new production capacity, the supply pressure was high. The downstream's intention to stock up was not high, and the industry continued the inventory - accumulation mode. The chlor - alkali integration still had profits, and the cost support was not obvious. PVC may show a weak - oscillating trend [7]. - The caustic soda futures dropped significantly. There was still the phenomenon of vehicle detention by downstream buyers, and the purchase price may be further reduced, with the inventory increasing compared with the previous period. There are small - scale maintenance plans for caustic soda in North China and East China in October, and the supply is still under high - pressure operation due to remaining profits. The liquid - caustic soda inventory of alumina plants in Shanxi and Henan is high, and the downstream profit is shrinking, with resistance to high prices. The weak - reality pattern continues, but the strong expectation of possible restocking demand before the future downstream alumina production cannot be falsified. It is recommended to wait and see [7] Soda Ash - Glass - The price of soda ash futures was weakly operating. Before the holiday, the inventory was mainly reduced, and it increased after the holiday. The rigid demand for heavy soda was stable. The production capacity of float glass and photovoltaic glass has been stable recently. The inventory of the photovoltaic industry has changed from decreasing to increasing, and it is expected that the ignition speed will slow down in the future, with limited incremental rigid demand for heavy soda. There are few maintenance plans in October, and the industry currently has little operating pressure, with high - pressure supply. The long - term pattern of supply - demand surplus remains unchanged, and opportunities to short at high prices should be sought, but caution should be exercised near the cost [8]. - The price of glass futures fluctuated narrowly. During the holiday, downstream enterprises had holidays, and the production and sales were insufficient, with seasonal inventory accumulation in the industry. Some regions raised their quoted prices. The daily melting volume was oscillating at a relatively high level. The processing orders improved but were still insufficient on a month - on - month basis, and some engineering orders increased. The situation of whether Shahe will centrally use Zhengkang's deep - processed gas should be continuously tracked. If the production - capacity reduction does not actually occur, the market may return to weak - reality trading, but with the current low valuation, the decline is expected to be limited. A low - buying strategy near the cost can be considered in the future [8]

Report Industry Investment Ratings - Urea, Methanol, Pure Benzene, Styrene, Propylene, Plastic, PVC, Caustic Soda, PX, PTA, Ethylene Glycol, Short Fiber, Glass, Soda Ash, Bottle Chip: Investment ratings are provided with star symbols, where red stars represent a predicted upward trend and green stars represent a predicted downward trend. One star means a bias towards long/short with a driving force for an upward/downward trend but limited operability on the trading floor. Two stars mean holding long/short with a clearer upward/downward trend and the market condition is evolving. Three stars mean an even clearer long/short trend and there are still relatively appropriate investment opportunities. White stars mean the short-term long/short trend is in a relatively balanced state and the current trading floor has poor operability, suggesting a wait-and-see approach [1][9] Core Views - The chemical market shows a complex situation with different trends in various sub - sectors. Some products are affected by factors such as supply - demand imbalances, seasonal changes, and raw material price fluctuations [2][3][5] Summary by Related Catalogs Olefins - Polyolefins - Propylene prices continued to rise due to early planned maintenance of a device in Dongying during the National Day holiday and the gradual recovery of some downstream demand. However, the futures price fell on the first trading day after the holiday, resulting in a divergence between the futures and spot markets and an expansion of the basis. - For polyolefins, the peak season demand was weak, with mainly rigid demand procurement. The large - scale release of new production capacity on the supply side led to a significant increase in domestic production this year, resulting in prominent supply - demand contradictions. Production enterprises accumulated inventory during the double festivals, and there was obvious pressure to reduce inventory after the holiday, causing prices to be under pressure [2] Pure Benzene - Styrene - During the National Day, the oil price fell. The pure benzene futures price once dropped below 5700 yuan/ton in the morning session and then rebounded following the oil price in the afternoon. The spot price in East China was weak, the shipment in Shandong was dull, and the listed price of Sinopec remained stable. The device operation rate continued to rise, the port inventory decreased, the actual fundamentals were okay, but the basis weakened compared to before the holiday. High import volume and the expectation of future demand decline continued to drag down the market. - The main contract of styrene futures closed slightly lower within the day, and the overall center of gravity moved down along the 5 - day moving average. The oil price first decreased and then increased during the holiday, remaining basically the same as before the holiday, having limited impact on the cost side of styrene. On the supply - demand fundamentals, the peak season demand was weak. Due to the expansion of production capacity, the domestic supply increased significantly. The total inventory of styrene has been significantly higher year - on - year since this year, showing a trend of oscillatory inventory accumulation after June. The supply - side pressure was large, suppressing the styrene price, and the styrene market was in a bearish pattern [3] Polyester - The overseas oil price fell during the holiday. The prices of PX and PTA weakened in the morning session and then rebounded in the afternoon due to the oil price recovery. The operation rate of PX continued to increase. Hengli Dalian's PTA carried out maintenance, and the East China device reduced its load due to an accident. In the short term, PX was expected to be under pressure, and the PTA segment repaired its profit. However, the PX of Wushi Petrochemical was planned for maintenance, and the polyester load was expected to be maintained. The short - term supply - demand pattern of upstream raw materials was okay. Attention should be paid to terminal orders and raw material restocking. In mid - to late October, the downstream demand was expected to gradually weaken, and the supply - demand situation would still be under pressure in the long run. - The domestic operation rate of ethylene glycol increased significantly, and the port inventory accumulated significantly during the holiday. The fundamentals were weak, and the main futures price once approached the 4100 yuan/ton mark within the day. In the medium term, with the mass production of new devices and the weakening of future demand, the supply - demand situation would gradually weaken in the fourth quarter. Under the expectation of inventory accumulation, the 1 - 5 spread was under pressure to decline. - The new production capacity of short fiber was limited, and the operation rate was at a high level. The terminal weaving and dyeing industries increased their operation rates. The recovery of peak - season demand boosted the short - fiber industry. It was recommended to continue to be long in the short term. Attention should be paid to downstream orders and short - fiber inventory. The operation rate of bottle chips increased, but after the long holiday, as the weather turned cooler, the demand was expected to weaken. Overcapacity was a long - term pressure, and the processing margin was continuously under pressure [5] Coal Chemical Industry - The methanol futures price dropped significantly. During the holiday, the import volume remained high, and the port inventory continued to accumulate. The capacity utilization rate of domestic methanol devices increased. Before the holiday, inland olefin enterprises made large - scale external purchases, and enterprises had sufficient orders to be delivered, but the order execution was slowed down due to logistics restrictions, and the inventory of production enterprises increased slightly. The import was expected to remain sufficient, the port was expected to continue to accumulate inventory, and the short - term weakness would continue. The long - term outlook was relatively positive. Attention should be paid to macro - sentiment and changes in overseas devices. - During the National Day holiday, urea production enterprises significantly accumulated inventory, the supply remained high, and enterprises faced great pressure to sell. Affected by weather and logistics factors, the downstream demand was insufficient. Export orders were being shipped, and the port inventory decreased. Although India issued a new round of urea tenders, planning to import 2 million tons, the export window period might have ended, so the short - term boost to the market was limited. The domestic supply - demand situation of urea remained loose. Attention should be paid to possible policy adjustments and their impact on market sentiment [6] Chlor - alkali Industry - The main contract of PVC dropped. During the holiday, the downstream demand weakened, the supply was at a high level, and the inventory increased significantly. After the end of maintenance and the release of new production capacity, the supply pressure was high. The downstream's intention to stock up was low, and the industry continued the inventory - accumulation pattern. The integrated chlor - alkali enterprises still had profits, but the cost support was not obvious. In a weak real - situation pattern, PVC might show a weak - oscillatory trend. - The caustic soda futures price dropped significantly. There were still vehicle - waiting phenomena among downstream buyers, and the purchase price might be further reduced. The inventory increased compared to the previous period. There were maintenance plans for caustic soda in North and East China in October, but the scale was small. Since there were still profits, the supply was still operating at a high level. The liquid caustic soda inventory of alumina plants in Shanxi and Henan was high, and the downstream profit margin shrank. They were resistant to high - priced products. The weak real - situation pattern continued, but there might be restocking demand before the future downstream alumina production. Since the strong - expectation could not be falsified, it was recommended to wait and see [7] Soda Ash - Glass - The soda ash futures price was in a weak state. The inventory decreased before the holiday and increased after the holiday. The rigid demand for heavy soda was stable. The production capacity of float glass and photovoltaic glass has been stable recently. The inventory of the photovoltaic industry increased after a decrease. It was expected that the ignition speed would slow down in the future, and the incremental rigid demand for heavy soda was limited. There were few maintenance plans in October, the industry's current operating pressure was not large, and the supply would operate at a high level. The long - term supply - demand surplus situation remained unchanged. Opportunities to short at high prices should be sought, but be cautious when approaching the cost level. - The glass futures price fluctuated within a narrow range. During the holiday, downstream enterprises had holidays, and the production and sales were insufficient. The industry seasonally accumulated inventory, and some regions increased their quoted prices. The daily melting volume was oscillating at a relatively high level. The processing orders improved but were still insufficient on a month - on - month basis, and some project orders increased. Whether Shajiahe would intensively use Zhengkang's deep - processed gas should be continuously monitored. If the production - capacity reduction does not actually occur, the market may return to the weak - real - situation trading. However, with the current low valuation, the expected decline range is also limited. In the future, a low - buying strategy near the cost level can be considered [8]

Some products are facing supply pressure and weak demand, while others have certain support from demand but also face future uncertainties [2][3][5] Summary by Category Olefins - Polyolefins - Olefin futures' main contracts fluctuated narrowly. Supply is controllable as restarting devices are not in place, and downstream demand provides some price support [2] - Polyolefin futures' main contracts also fluctuated narrowly. Polyethylene maintenance decreased with increased domestic production, and downstream has pre - holiday stocking demand but faces post - holiday de - stocking pressure. Polypropylene prices are under pressure due to multiple factors such as demand differentiation, supply pressure, and high inventory [2] Pure Benzene - Styrene - Pure benzene oscillated downward. Although the current fundamental situation is okay with port inventory decreasing and spot price being relatively firm, high import volume and expected demand decline drag the market [3] - Styrene futures' main contracts fluctuated narrowly. Cost - end oil price provides support, but high inventory suppresses the price [3] Polyester - PX's strong expectation weakened, and PTA's profitability is still poor. Although the pre - holiday stocking in the polyester yarn industry has reduced inventory pressure, post - holiday demand is expected to weaken, and the supply - demand situation remains under pressure [5] - Ethylene glycol's domestic operation decreased slightly, and port inventory is low. However, new device trials and weakening demand may lead to a weak supply - demand situation in the fourth quarter [5] - Short - fiber's new capacity is limited, and inventory decreased. The pre - holiday stocking has fulfilled the positive expectation. Bottle chips showed a short - term strong trend due to typhoon - affected device shutdown, but long - term over - capacity is a pressure [5] Coal Chemical Industry - Methanol's main contract oscillated. Port inventory is expected to increase after the holiday, and the market is expected to be weak [6] - Urea prices increased slightly, but downstream follow - up is cautious. The domestic supply - demand situation is loose, and attention should be paid to policy adjustments [6] Chlor - Alkali - PVC oscillated weakly with high supply and high inventory. Domestic downstream pre - holiday stocking intention is low, and foreign demand is weak [7] - Caustic soda's futures price oscillated under the weak situation. Although there is an expectation of downstream stocking before alumina production, the current supply is high [7] Soda Ash - Glass - Soda ash weakened. The industry is de - stocking, and the downstream pre - holiday stocking is nearly over. The long - term supply is in excess [8] - Glass prices fell from a high level.

Report Industry Investment Rating - There is no information about the report industry investment rating in the provided content. Core Viewpoints of the Report - The polyester industry is facing a situation where raw material production is imminent, leading to a pattern of loose supply and demand. In Q4 2025, prices of PX, PTA, and MEG are expected to be under pressure due to factors such as cost - end crude oil price fluctuations, new device productions, and changes in supply - demand relationships [2][135][136][137]. Summary According to the Table of Contents 1. PX&PTA&MEG Price: Cost - end Crude Oil Price is Under Pressure - From June 30 to September 23, 2025, prices of various products in the polyester industry chain showed different trends. For example, the price of Brent crude oil increased slightly by $0.2 per barrel, while the price of PTA decreased by 579 yuan/ton [4]. - The futures prices of PX, PTA, and MEG also declined from June 30 to September 24, 2025, with PTA down 3.6%, MEG down 0.8%, and PX down 2.9% [7]. 2. PX: Newly Added Device Capacity is Limited - In 2025, the average operating load of Asian PX was 74.29% from January to September, a year - on - year decrease of 1.07 percentage points, while that of China was 82.37%, a year - on - year increase of 0.16 percentage points. The new PX device of Yulong Petrochemical has a capacity of 300 tons/year but only produces MX currently [14]. - From January to August 2025, the cumulative import volume of PX was 615.83 million tons, a year - on - year increase of 6.5%. However, the import volume is expected to shrink in Q4 due to more TA maintenance and weakened market demand [21]. 3. PTA: New Devices are Put into Production, and Supply - demand is Loose - From January to September 2025, the average operating load of domestic PTA was 77.54%, a year - on - year decrease of 1.84 percentage points, and the average processing fee was 241 yuan/ton, a year - on - year decrease of 40 yuan/ton. In Q3, Sanfangxiang's 320 - million - ton new capacity was put into production, and in Q4, Dushan Energy's 300 - million - ton capacity is planned to be put into production [24]. - From January to August 2025, PTA production was 48.45 billion tons, a year - on - year increase of 3.4%. The cumulative export volume from January to August was 2.5302 billion tons, a year - on - year decrease of 16.86%. Overall, PTA is expected to accumulate inventory in Q4 [27][33][34]. 4. MEG: Coal - based Profit is Good, Device Restart is Active, and Inventory Accumulation Expectation is Strengthened - From January to August 2025, the domestic production of ethylene glycol was 13.398 billion tons, a year - on - year increase of 7.8%. The average operating load of ethylene glycol in the Chinese mainland was 69.71%, a year - on - year increase of 5.24 percentage points, and that of coal - based ethylene glycol was 70.18%, a year - on - year increase of 7.32 percentage points [42][43]. - In 2025, the planned production capacity of MEG devices is 1.6 billion tons, and from January to August, the cumulative import volume was 5.0284 billion tons, a year - on - year increase of 16%. There is a strong expectation of inventory accumulation in Q4 [45][48][49]. 5. Polyester Demand Situation: Demand is Advanced, and Q4 Demand is Weak - In 2025, many domestic polyester devices are being put into production, and the planned production capacity in Q4 is mainly for filament. However, the current terminal performance is lower than expected, showing a situation of "Golden September and Silver October" not being prosperous [56][57]. - From January to August 2025, the total export volume of Chinese polyester products was 96.196 billion tons, a year - on - year increase of 15.8%. However, India has launched an anti - dumping sunset review investigation on Chinese polyesters, which may affect future exports [65]. 6. PX&PTA&MEG Position Situation - On September 25, 2025, compared with June 30, 2025, the total position volume of PTA decreased by 260,054 hands, that of MEG decreased by 5,251 hands, and that of PX increased by 46,758 hands [104].

1. Chlor - Alkali Industry Report Industry Investment Rating Not provided Core Viewpoints - For caustic soda, in Q4, the downside space is limited. There may be concentrated stocking behavior in Q4 due to alumina's planned production in Q1 next year. Short - term demand has support, but future alumina purchase prices may be lowered [2]. - For PVC, in Q4, the downside space is limited during the peak season. The supply is in an excess pattern, and the demand in Q3 did not show well. Exports have alleviated some excess pressure, and attention should be paid to cost support and downstream demand [2]. Summary by Catalog - **Prices**: On September 26, compared with September 25, the prices of some caustic soda and PVC products changed. For example, the price of Shandong 32% liquid caustic soda (converted to 100%) remained unchanged at 2500 yuan/ton, while the price of East China calcium carbide - based PVC decreased by 20 yuan/ton to 4740 yuan/ton [2]. - **Supply**: The overall start - up rate of the PVC industry increased by 0.7 percentage points to 76.1% on September 26 compared with September 19.

For example, the start - up rate of the alumina industry remained unchanged at 83.7%, and the start - up rate of the Longzhong sample pipe industry increased by 1.3 percentage points to 40.4% [2]. - **Inventory**: As of September 25, compared with September 18, the inventory of liquid caustic soda in East China factories and Shandong increased, while the total social inventory of PVC remained unchanged at 53.5 million tons [2]. 2. Polyester Industry Chain Report Industry Investment Rating Not provided Core Viewpoints - For PX, in Q4, the supply - demand is expected to be weak, and the price will be under pressure. Strategies include shorting on rebounds and reverse - arbitraging on high spreads [6]. - For PTA, in Q4, the supply - demand is expected to be weak, and it will follow the cost side to fluctuate weakly. Strategies include shorting on rebounds and reverse - arbitraging on the TA1 - 5 spread [6]. - For ethylene glycol, in Q4, it is expected to enter the inventory accumulation stage, and the price is under pressure. Strategies include shorting EG01 and reverse - arbitraging on the EG1 - 5 spread [6]. - For short - fiber, in the short - term, the price may be supported, but if the terminal demand in October cannot follow up, the supply - demand will turn to an expected pattern, and the processing fee is expected to be compressed [6]. - For bottle - chips, in Q4, it is likely to enter the seasonal inventory accumulation stage, and the processing fee is under pressure. Strategies include following the PTA for single - side trading and shorting the processing fee on high spreads [6]. Summary by Catalog - **Prices**: On September 26, compared with September 25, the prices of various products in the polyester industry chain changed. For example, the price of POY150/48 increased by 75 yuan/ton to 6605 yuan/ton, and the price of PTA East China spot increased by 5 yuan/ton to 4590 yuan/ton [6]. - **Supply - demand and Inventory**: In Q4, the supply of PX and domestic ethylene glycol is expected to be high, while the demand of downstream products such as PTA and bottle - chips is in the off - season. The inventory of MEG ports and domestic urea is also in a state of change [6]. - **Start - up Rate**: The start - up rates of various industries in the polyester industry chain changed weekly. For example, the start - up rate of Asian PX decreased by 0.2 percentage points to 78.0%, and the start - up rate of domestic PTA remained unchanged at 76.8% [6]. 3. Polyolefin Industry Report Industry Investment Rating Not provided Core Viewpoints - For LLDPE and PP, currently, the inventory of PE and PP has decreased. However, after the holiday, there is a large inventory pressure, and with new capacity coming on - stream, the inventory accumulation pressure of the 01 contract is large, which limits the upside space [9]. Summary by Catalog - **Prices**: On September 26, compared with September 25, the prices of L2601, PP2601 and other contracts decreased slightly. For example, the closing price of L2601 decreased by 10 yuan/ton to 7159 yuan/ton [9]. - **Inventory**: As of the relevant update time, the enterprise inventory and social inventory of PE and PP decreased. For example, the PE enterprise inventory decreased by 3.2 million tons to 45.8 million tons [9]. - **Start - up Rate**: The start - up rates of PE and PP devices increased. For example, the start - up rate of PE devices increased by 1.48 percentage points to 81.8%, and the start - up rate of PP devices increased by 0.63 percentage points to 75.5% [9]. 4. Methanol Industry Report Industry Investment Rating Not provided Core Viewpoints - In the short - term, methanol will continue to fluctuate. The supply side has a balance between the resumption of some domestic devices and the expected reduction of overseas supply.
