1. Report Industry Investment Rating No information provided. 2. Core View of the Report The polyester market is expected to continue its weak and volatile trend due to the weakening cost support and inventory pressure. The PX - PTA segment faces dual pressures from cost and demand, and the downstream products' price cuts for inventory reduction may further squeeze profit margins [1][4]. 3. Summary by Relevant Catalogs 3.1 Daily Market Summary 3.1.1 PTA & PX - **Price**: On October 20, the PX main contract closed at 6,268.0 yuan/ton, down 0.38% from the previous trading day, with a basis of -37.0 yuan/ton. The PTA main contract closed at 4,384.0 yuan/ton, down 0.41%, with a basis of -44.0 yuan/ton. The Brent crude oil main contract closed at 61.34 US dollars/barrel, and WTI at 57.25 US dollars/barrel [2]. - **Supply**: The PX plant operating rate shows no obvious contraction signal, and with the expected new capacity, there is still incremental pressure on the supply side. The PTA plant maintenance is insufficient, the operating rate remains at a medium - high level, and the expected new plant commissioning will intensify the supply - loose pattern. The decline in the crude oil price center weakens the PX cost support, and the PX processing fee is expected to be compressed, which may force the PTA cost line to sink [2]. - **Demand**: The polyester factory operating rate is restricted by the weak terminal orders. The 15 - day average turnover of China Textile City decreased by 23.7% month - on - month, and the falsification of peak - season demand accelerates the negative feedback transmission in the industrial chain. The low sales rate of polyester filament suppresses the polyester operating elasticity, and the marginal driving force on the PTA demand side is further weakened [3]. - **Inventory**: The PTA factory inventory has exceeded the high point of the same period in the past three years, and the social inventory days have climbed to 7 - 8 days. The continuous weakening of the inter - month spread reflects the intensifying inventory - accumulation pressure. In the low - processing - fee environment, the factory's price - support ability is weakened, and the high inventory may force the plant to reduce production in advance, but the pattern of strong supply and weak demand is difficult to change in the short term [3]. 3.1.2 Polyester - **Price**: On October 20, the short - fiber main contract closed at 6,028.0 yuan/ton, down 0.13% from the previous trading day. The spot price in the East China market was 6,285.0 yuan/ton, down 5.0 yuan/ton, with a basis of 257.0 yuan/ton [4]. - **Demand**: The MA15 turnover of China Textile City decreased from 851.8 million meters on October 10 to 855.87 million meters on October 20, indicating weak terminal textile demand [4]. - **Inventory**: The inventories of polyester staple fiber (6.11 days), polyester filament DTY (31.5 days), and FDY (26.1 days) are all higher than the 5 - year average values (4.96/28.42/22.19 days). The inventory pressure of DTY is significant, and although the POY inventory (16.8 days) is lower than the average of 20.40 days, the de - stocking rhythm is blocked [4]. 3.2 Industrial Chain Price Monitoring - **PX**: The main contract price of PX futures decreased by 0.38%, the trading volume increased by 36.35%, and the open interest increased by 10.50%. The spot prices in China's main port CFR and South Korea FOB remained unchanged [5]. - **PTA**: The main contract price of PTA futures decreased by 0.41%, the trading volume increased by 14.03%, and the open interest increased by 4.00%. The spot price in China's main port CFR remained unchanged. The PTA 1 - 5, 5 - 9 spreads decreased, while the 9 - 1 spread increased. The import profit decreased slightly [5]. - **Short - fiber**: The main contract price of short - fiber futures decreased by 0.13%, the trading volume decreased by 7.67%, and the open interest decreased by 0.58%. The spot price in the East China market decreased slightly, and the PF 1 - 5, 9 - 1 spreads increased, while the 5 - 9 spread decreased [5]. - **Other products**: The prices of Brent crude oil, WTI, CFR Japan naphtha, ethylene glycol, polyester chips, and most polyester filaments remained unchanged, while the price of polyester bottle chips decreased by 0.27% [5]. - **Processing spreads**: The processing spreads of naphtha, PX, polyester chips, and most polyester filaments remained unchanged, while the PTA processing spread decreased by 1.26%, and the polyester bottle chip processing spread decreased by 6.36% [6]. - **Light - textile city turnover**: The total turnover on October 20 was 653 million meters, a month - on - month decrease of 25.03%. The turnover of long - fiber fabrics decreased by 19.48%, and that of short - fiber fabrics decreased by 42.79% [6]. - **Industrial chain load rate**: The operating rates of PTA factories, polyester factories, and Jiangsu - Zhejiang looms remained unchanged [6]. - **Inventory days**: The inventory days of polyester staple fiber decreased by 19.39%, while those of POY, FDY, and DTY increased by 23.53%, 8.30%, and 9.00% respectively [6]. 3.3 Industry Dynamics and Interpretation 3.3.1 Macroeconomic Dynamics - On October 20, Fed's Musalem said that if employment faces more risks and inflation is under control, he may support another interest - rate cut. The Israel - Hamas conflict continued with various statements and actions from both sides [7]. - On October 17, various Fed officials had different views on interest - rate cuts. The World Gold Council research head said the gold market was not saturated, and the Shanghai Gold Exchange called for risk control [7]. 3.3.2 Supply - Demand - Demand On October 20, the total turnover of China Textile City was 653.0 million meters, a month - on - month decrease of 25.03%, with 529.0 million meters of long - fiber fabric turnover and 123.0 million meters of short - fiber fabric turnover [9]. 3.4 Appendix - Analysis of Future Price Trends - **Supply side**: PX and PTA may have sufficient supply. The high operating rate of PX and PTA plants and the expected new capacity may lead to an oversupply situation. The decline in crude oil prices may reduce PX costs, but the impact on supply also depends on refineries' production willingness [36]. - **Demand side**: The turnover of China Textile City has declined, indicating weak polyester demand. The weak downstream demand may lead to a decline in polyester operating rates, which in turn suppresses PTA prices [37]. - **Inventory side**: The high PTA factory inventory indicates great inventory - accumulation pressure. The combination of high supply, weak demand, and high inventory may lead to further inventory accumulation and price suppression [37].

Group 1: Report Industry Investment Rating - No relevant information provided Group 2: Core Views of the Report - PTA supply side is contracting, with Ningbo Yisheng Petrochemical Phase 4 reducing its load by 50% until the end of the month. PTA processing fees remain low, and industry profits are still constrained by over - capacity due to new plant commissions. [2] - Polyester downstream load remains above 90%, but high load has not led to large - scale inventory accumulation. With the end of the "Golden September and Silver October" period, there are concerns that subsequent textile and clothing demand will be affected by the trade war. [2] - PTA's operating rate may decline further, and due to the decline in crude oil prices, it is difficult for PTA to have an independent market.

Report Summary 1) Report Industry Investment Rating No information provided. 2) Core View of the Report - PTA supply is shrinking, with Ningbo Yisheng Petrochemical Phase 4 reducing its load by 50% until the end of the month. However, its processing fee remains low due to over - capacity from new device production. The polyester downstream load is high, but there are concerns about textile and clothing demand after the "Golden September and Silver October" period due to trade wars. PTA's upward movement is restricted by falling crude oil prices [2]. - For ethylene glycol, the inventory at East China ports is low, and the expected import volume from overseas markets is decreasing. However, domestic device production is putting pressure on prices. With the end of the polyester peak season and the downward movement of the crude oil fundamentals, polyester is expected to operate weakly [2]. 3) Summary by Relevant Catalogs Market Quotes - **PTA**: The price of INE crude oil rose from 432.6 yuan/barrel to 435.8 yuan/barrel, PTA - SC decreased from 1258.3 yuan/ton to 1217.0 yuan/ton, and the PTA/SC ratio dropped from 1.4002 to 1.3843.

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views of the Reports - **Polyester Industry**: In the short term, PX, PTA, and other products are mainly in a weak shock state. The supply of PX is expected to shrink, but the overall supply - demand is still weak. PTA's basis has weakened, and the supply of ethylene glycol is abundant with a high probability of inventory accumulation. Short - fiber prices are supported by low inventory, and bottle - chips may enter a seasonal inventory accumulation channel [1]. - **Pure Benzene - Styrene Industry**: The supply - demand of pure benzene in October is expected to be loose, and the price drive is weak. The supply - demand of styrene is also expected to be loose, and the price is under pressure in the short term [2]. - **PVC and Caustic Soda Industry**: The demand for caustic soda is weakly supported in the short term but may have support in the medium - long term. The supply - demand pressure of PVC is large, and the price is weak, but the cost end provides bottom support [3]. - **Methanol Industry**: The price of methanol may continue to fluctuate. Attention should be paid to the stability of overseas device operation, the clearance efficiency of sanctioned vessels, and the actual arrival performance [4]. - **Polyolefin Industry**: The supply - demand structure of polyolefins is loose, and the upside space of the 01 contract is limited. The prices of PP and PE are under pressure [6]. 3.

Report Industry Investment Ratings - Propene, plastic: ★☆☆, indicating a bullish/bearish bias with limited operability on the market [1] - Pure benzene, styrene: ★★★, suggesting a clearer bullish/bearish trend with appropriate investment opportunities [1] - PX, PTA, ethylene glycol, short - fiber, bottle chips, methanol, soda ash: ☆☆☆, meaning a relatively balanced short - term trend with poor operability, advising to wait and see [1] - Urea, PVC, glass: ★★★, representing a clearer bullish/bearish trend and current investment opportunities [1] - Caustic soda: ★★★★, not clearly defined in the star - rating description but presented in the table [1] Core Viewpoints - The overall chemical market shows mixed trends, with different products facing various supply - demand situations and price movements. Some products are in a weak position due to factors like increased supply and weak demand, while others have signs of improvement in trading volume or short - term support [2][3][5] Section Summaries Olefins - Polyolefins - Propene futures dropped to a new low for the year. Producers want to stabilize the market, and downstream purchases increased with better trading volume [2] - Polyethylene and polypropylene futures were weak. Polyethylene faced post - holiday inventory build - up, and price cuts couldn't boost sales significantly. Polypropylene will have more supply due to new capacity and less maintenance, with poor downstream orders and high inventory [2] Pure Benzene - Styrene - The pure benzene market declined, with larger drops in the unified benzene disk and spot prices. High imports are a major pressure. The benzene - styrene futures fell, with cost support weakening, but short - term supply - demand improved slightly [3] Polyester - PX supply decreased due to maintenance, while PTA supply is expected to increase. The polyester industry has a weak outlook with potential inventory build - up for PTA. Ethylene glycol inventory continued to rise, and its price depends on raw materials. Short - fiber had good inventory reduction and was bullish in the short - term. Bottle chips' demand will weaken with the cooling weather and face long - term over - capacity [5] Coal Chemical Industry - Methanol imports at coastal areas may slow down, but port inventory is still affected by high planned arrivals. Domestic production is high, and demand is weak, with short - term policy - driven market fluctuations and long - term price increase expectations [6] - Urea futures are in a narrow range. Supply is abundant due to weather - affected demand, but exports may support prices, and the market will continue to oscillate at a low level [6] Chlor - Alkali - PVC supply decreased slightly but remained high. Domestic demand was stable, and exports were good in September but may face policy pressure. It may trend weakly [7] - Caustic soda production decreased due to maintenance, and inventory dropped. Downstream demand is uncertain, and short - selling should be cautious due to high basis [7] Soda Ash - Glass - Soda ash supply was high despite a small production decline. Downstream demand growth was limited, and it's advisable to short at high prices after a rebound [8] - Glass prices continued to fall with inventory build - up. Supply was high, and demand was weak. The decline may be limited at low valuations, and selling out - of - the - money put options can be considered [8]

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - PTA is expected to experience weak oscillations in the short - term due to macro - level disturbances, a slight increase in supply, mediocre demand during the traditional peak season, and a pessimistic long - term supply - demand outlook. The industry should continue the strategy of hedging at high prices and pay attention to unplanned production cuts or halts [6]. - Ethylene glycol (MEG) is likely to maintain a weak pattern in the short - term as there is a strong expectation of a weakening in supply - demand balance and inventory is accumulating at the main ports [6]. Summary by Directory 1. Upstream Analysis of the Industrial Chain - **Market Review**: International oil prices declined due to the International Energy Agency's warning of long - term supply surplus and trade disputes initiated by the US. PX prices dropped, but the decline was less than that of crude oil because of weak cost support and a low PX - naphtha spread. As of October 17, the Asian PX closing price was $783.17/ton CFR China, down $15/ton or 1.88% from October 10 [15]. - **PX Capacity Utilization**: The average weekly PX capacity utilization rate was 87.42%, a 0.81% decrease from the previous week. Urumqi Petrochemical's 1 million - ton device was under maintenance from October 14 for half a month, and Fujia Dahua's two 1.4 - million - ton devices continued to be under maintenance, with a planned restart in early November [20]. - **PX - Naphtha Spread**: As of October 17, the PX - naphtha spread reached $246.2/ton, up $24.75/ton from October 10. The spread continued to recover due to low processing fees, low production willingness of enterprises, and a short - term shortage of spot in November [23]. 2. PTA Fundamental Analysis - **Market Review**: PTA prices oscillated weakly. Although the supply was tightened by a planned production cut of a major producer in the Northeast, the price was dragged down by lower international oil prices due to tariff disputes and weak long - term industry expectations. As of October 17, the PTA spot price was 4340 yuan/ton, and the spot basis was 2601 - 83 [26]. - **PTA Capacity Utilization**: The average weekly PTA capacity utilization rate dropped to 75.56%, a 2.28% decrease from the previous week. Hengli Petrochemical carried out a planned production cut, while Yisheng New Materials increased its load during the week. In October, there are maintenance plans for Ineos and Hengli, and the restart time of Yisheng Dahua and Hainan is uncertain, so the monthly PTA output may increase significantly [29]. - **PTA Processing Fees**: PTA processing fees were under pressure as the international oil prices continued to decline due to the ongoing tariff disputes, and there was a lack of positive support in the industrial chain. Next week, with the planned restart of maintenance devices and little change in the polyester sector, the destocking rate in the balance sheet will narrow, and PTA processing fees may continue to be under pressure [31]. - **PTA Supply - Demand Balance**: In October, with insufficient PTA device maintenance and the restart of maintenance devices, and little change in demand, the PTA supply - demand is expected to be in a loose balance [34]. 3. MEG Fundamental Analysis - **Market Trend**: Ethylene glycol prices declined weakly under the double pressure of cost and supply - demand. Affected by the expectation of increased supply and the decline of international oil prices, upstream raw materials were in a downward trend. Although there was a rebound on Thursday due to the general rise of commodities, it continued to be weak on Friday due to the drag of crude oil. As of October 17, the closing price of ethylene glycol in Zhangjiagang was 4096 yuan/ton, and the delivered price in the South China market was 4230 yuan/ton [40]. - **MEG Capacity Utilization**: The total ethylene glycol capacity utilization rate was 69.05%, a 0.37% decrease from the previous week. The capacity utilization rate of integrated devices was 68.93%, a 1.07% decrease, while the coal - based ethylene glycol capacity utilization rate was 69.24%, a 0.75% increase. In October, the inventory accumulation at ports is limited due to cautious import expectations, but there is an obvious expectation of increased domestic production [44]. - **MEG Port Inventory**: As of October 22, 2025, the total expected arrival volume of ethylene glycol in East China was 893,000 tons. As of October 16, the total inventory of MEG in the main ports of East China was 493,000 tons, an increase of 14,200 tons from October 13 [46]. - **MEG Processing Profits**: The prices of ethylene glycol were weak, and the processing profits of various processes showed both increases and decreases. As of October 17, the profit of naphtha - based ethylene glycol production was - $108.89/ton, an increase of $17.29/ton from the previous week, while the profit of coal - based ethylene glycol production was - 470.2 yuan/ton, a decrease of 181.7 yuan/ton from the previous week [51]. 4. Downstream Demand Analysis of the Industrial Chain - **Polyester Device Load**: The polyester devices had no clear changes. The average weekly polyester capacity utilization rate was 87.78%, a 0.02% decrease from the previous week. Next week, the polyester load is expected to gradually increase as previously commissioned devices and long - shut - down devices restart, and new devices are planned to be commissioned [54]. - **Polyester Capacity Utilization Outlook**: In September, the average monthly polyester capacity utilization rate was 87.59%, a 1.12% increase from the previous month. After successful destocking before the festival, the polyester inventory in October is under little pressure, and the monthly polyester load is expected to remain stable [55]. - **Capacity Utilization of Polyester Products**: The average weekly capacity utilization rate of polyester filament was 91.06%, a 0.03% decrease from the previous period. The average capacity utilization rate of polyester staple fiber was 87.16%, unchanged from the previous week. The capacity utilization rate of fiber - grade polyester chips was 85.12%, a 0.39% decrease from the previous week [60]. - **Polyester Product Inventory**: Due to weak downstream purchasing enthusiasm, the finished - product inventory of polyester factories accumulated slightly during the week [63]. - **Polyester Product Cash Flow**: The polymerization cost decreased, and the price decline of polyester products was less than that of raw materials, so the cash flow of most models was restored [64]. - **Weaving Load**: As of October 16, the comprehensive operating rate of chemical fiber weaving in the Jiangsu and Zhejiang regions was 64.06%, unchanged from the previous data. The average terminal weaving order days were 14.79 days, an increase of 0.50 days from the previous week. In mid - October, the weaving market orders were differentiated, and the order volume increased slightly compared with September, but the overall increase was not significant due to the temperature difference between the north and the south [69]. 5. Summary of the Polyester Industrial Chain Fundamentals - **Cost**: International oil prices declined. PX prices also dropped, but the decline was less than that of crude oil due to a low PX - naphtha spread [71]. - **Supply**: The average weekly PTA capacity utilization rate decreased, and the total ethylene glycol capacity utilization rate also declined slightly, with different trends in integrated and coal - based devices [71]. - **Demand**: The average weekly polyester capacity utilization rate decreased slightly, and the weaving operating rate in the Jiangsu and Zhejiang regions remained stable. The weaving orders increased slightly but were still affected by temperature differences [71]. - **Inventory**: PTA is expected to be tight in the near - term but face inventory accumulation in the long - term. The MEG inventory in the main ports of East China increased [71].

1. Report Industry Investment Rating - The investment view is "oscillating", with no obvious driving force, and it is expected to mainly oscillate [4] 2. Core View of the Report - The report analyzes the polyester industry from multiple aspects including supply, demand, inventory, etc. It points out that the supply side of polyester has shrunk, the downstream load of polyester remains at about 90%, and the PTA port inventory has slightly increased. The PTA basis has stabilized, but the profit has continued to shrink. The PX - naphtha spread is at $250, and the PTA processing fee remains at around 200 yuan. The PTA price is at a neutral - low level, and the absolute price has further declined due to the fall in crude oil prices. The overall market is expected to oscillate mainly due to the lack of obvious driving factors [4] 3. Summary According to Relevant Catalogs 3.1 Main Views and Strategy Overview - **Supply**: It is bearish. The trade war may escalate, slightly affecting China's crude oil imports. The supply of domestic PTA devices has slightly shrunk, the PTA basis has stabilized, the PX device operating rate is stable, the cost has weakened, and although the PXN has expanded, polyester has followed the decline in crude oil [4] - **Demand**: It is bearish. The downstream load of polyester remains at about 90%, the inventory of polyester factories is optimistic, and it is necessary to pay attention to whether the weaving can maintain the load after the "Golden September and Silver October" [4] - **Inventory**: It is neutral. The port inventory of PTA has slightly increased, and the physical goods in the Ningbo direction are slightly in short supply [4] - **Basis**: It is bearish. The PTA basis has quickly stabilized, the PTA profit has continued to shrink, and the liquidity in the PTA market is still very loose [4] - **Profit**: It is bearish. The spread between PX and naphtha is $250, the PTA processing fee remains at around 200 yuan, and the PTA processing fee has expanded [4] - **Valuation**: It is neutral. The PTA price is at a neutral - low level. After the end of the domestic maintenance season, the reforming devices are gradually recovering, and the absolute price of PTA has further declined due to the fall in crude oil prices [4] - **Macro Policy**: It is neutral. On October 15, Fed Chairman Powell hinted that the Fed is planning to cut interest rates by 25 basis points later this month [4] - **Investment View**: It is oscillating. There is no obvious driving force, and it is expected to mainly oscillate [4] - **Trading Strategy**: For unilateral trading, it is recommended to wait and see, and pay attention to geopolitical risks [4] 3.2 Oil Product Fundamentals Overview - **Macro Situation**: On October 15, Fed Chairman Powell said that the US economy seems to be in a stable state, but the government shutdown may affect data collection. On October 17, major European stock indexes fell in early trading, with concerns about the banking industry spreading, and the European defense stocks also attracted attention [8] - **Gasoline**: The shutdown of the US government may affect demand in the off - season. The North American refinery load has declined, the total gasoline inventory has decreased by 1.6 million barrels, indicating strong terminal demand. The price of high - octane aromatics has remained relatively stable, and its spread with RBOB gasoline has remained stable at 68 cents [22] 3.3 Aromatic Hydrocarbon Fundamentals Overview - **Supply Increase**: With the commissioning of Yulong Petrochemical, the supply of MX is expected to increase in October.
