1. Report Industry Investment Rating - The investment view on polyester is "oscillating", expected to be mainly on the strong side, and the trading strategy for the unilateral position is to wait and see [4] 2. Core View of the Report - PX supply is tight and polyester exports may increase. The PX market price rebounds due to multiple factors, but production is limited by high gasoline profit margins and low benzene prices. Polyester downstream load remains at about 90%, and the inventory of polyester factories is optimistic. The PTA port inventory is accumulating, the PTA basis is weak, and the profit is at a low level. The PTA price is at a neutral - low position, and the macro - policy has a neutral impact. Overall, there is no obvious driving force, and it is expected to be mainly on the strong side [4] 3. Summary According to Relevant Catalogs 3.1 Main Views and Strategy Overview - **Supply**: PX market price rebounds. Although some planned maintenance has ended and production capacity is gradually recovering, PX output is still limited. Gasoline profit surge and low benzene price lead to reduced raw material input in aromatic hydrocarbon devices and lower load of reforming and STDP devices, restricting PX supply. PTA device maintenance increases slightly [4] - **Demand**: Polyester downstream load maintains at about 90%, the inventory of polyester factories is optimistic, and the downstream weaving performance is good recently [4] - **Inventory**: PTA port inventory accumulates 160,000 tons this week, and the market is continuously accumulating inventory [4] - **Basis**: PTA basis continues to be weak, and PTA profit remains at a low level [4] - **Profit**: The spread between PX and naphtha reaches $250, and the PTA processing fee remains at a low level of about 200 [4] - **Valuation**: PTA price is at a neutral - low position. With the decline of reforming device profit, the absolute PTA price rebounds under the tight PX situation [4] - **Macro - policy**: Geopolitical events such as the attack in the Black Sea port have a neutral impact [4] - **Investment view**: Oscillating, expected to be mainly on the strong side; trading strategy: unilateral position, wait and see [4] 3.2 Oil Product Fundamentals Overview - **Crude oil**: On November 12, OPEC changed its estimate of the global oil market from deficit to surplus due to higher - than - expected US production and increased OPEC supply. The OPEC + alliance may pause further production increases in Q1 2026. Geopolitical events such as the so - called "drug - busting" action of the US against Venezuela also affect the market [8] - **Gasoline**: US gasoline inventory is continuously decreasing. Gasoline cracking profit strengthens, increasing blending demand. The North American refinery start - up rate drops to 86.6%, crude oil inventory decreases by 6.9 million barrels, and imports also decline significantly. The low US gasoline inventory supports the aromatic hydrocarbon market, and high - octane aromatic hydrocarbon prices are strong. European refineries face challenges, and Ebob gasoline prices rise [25] 3.3 Aromatic Hydrocarbon Fundamentals Overview - **Supply contraction**: PX supply contracts, waiting for the annual contract negotiation results. Asian naphtha price strengthens but cracking profit is under pressure. South Korea reduces reforming device load due to declining aromatic hydrocarbon profit. Some Southeast Asian devices are under maintenance, promoting the expansion of Asian gasoline profit [44] - **Arbitrage space**: The cross - regional arbitrage space for aromatic hydrocarbons is opened, and physical goods circulation is in progress. The US - Asia spread of mixed xylene is about $257, theoretically supporting arbitrage imports [49] - **Profit situation**: Selective disproportionation profit declines, and reforming device maintenance increases. Pure benzene price rebounds slightly but still suppresses disproportionation profit. Gasoline reforming and aromatic hydrocarbon reforming profits both recover [45][55] - **PX situation**: Gasoline profit and low benzene price support PX. The PX market price rebounds, but production is limited. China's PTA production is close to a historical high, supporting PX consumption [55] 3.4 Polyester Fundamentals Overview - **Ethylene glycol**: East China ethylene glycol port inventory increases significantly. With new device commissioning, supply pressure increases. Coal - based ethylene glycol profit recovers. Sino - US trade negotiation progress is expected to boost textile and clothing export demand [78] - **Polyester**: Polyester maintains a high load, and weaving load is optimistic. Export demand may boost the market. Under the background of tight PX supply and stable polyester start - up, polyester exports are expected to increase due to favorable overseas export policies and improved Sino - US trade relations [65][88]

1. Report Industry Investment Rating - The investment view for the polyester industry is "oscillating", with no obvious driving force, and it is expected to mainly oscillate. The trading strategy for the unilateral position is to wait and see, and attention should be paid to geopolitical risks [5]. 2. Core View of the Report - The polyester market is affected by multiple factors. The supply of PTA has slightly shrunk, the downstream load of polyester remains at about 90%, the port inventory of PTA has slightly increased, the basis of PTA has stabilized, and the profit has continued to shrink. The price of PX has rebounded, and the profit has been significantly repaired. The market is expected to mainly oscillate due to the lack of obvious driving forces [5]. 3. Summary According to Relevant Catalogs 3.1 Main Views and Strategy Overview - **Supply**: The supply of domestic PTA devices has slightly shrunk, the PTA basis has stabilized, and the operating rate of PX devices has been stable, with the PXN expanding. It is bearish [5]. - **Demand**: The downstream load of polyester remains at about 90%, the inventory of polyester factories is optimistic, and the downstream weaving has performed well recently. It is expected that the current peak season can last until November. It is bullish [5]. - **Inventory**: The port inventory of PTA has slightly increased, with a 50,000 - ton increase in inventory this week. It is neutral [5]. - **Basis**: The PTA basis has quickly stabilized, and the PTA profit has continued to shrink. It is bearish [5]. - **Profit**: The spread between PX and naphtha is $250, and the processing fee of PTA remains below 200 yuan. It is bearish [5]. - **Valuation**: The PTA price is at a neutral - low level, the profit of the reforming device has declined, and the anti - involution news has disturbed the market, causing the absolute price of PTA to rebound. It is neutral [5]. - **Macro Policy**: On October 30 local time, the Chinese and US presidents held a meeting. It is neutral [5]. - **Investment View**: There is no obvious driving force, and it is expected to mainly oscillate [5]. - **Trading Strategy**: The unilateral position should wait and see, and attention should be paid to geopolitical risks [5]. 3.2 Oil Product Fundamentals Overview - **Crude Oil**: North American crude oil inventories are at a recent low, and the US has imposed new sanctions on two Russian oil companies. The market fundamentals support oil prices, with a decrease in US crude oil inventories and a large drop in gasoline inventories, both slightly below the five - year average level. The refinery operating rate has risen from 85.7% to 88.6%. Crude oil and gasoline markets have strengthened under the tightening supply and geopolitical risks, but the reforming oil has performed relatively weakly [7][29]. - **Gasoline**: US gasoline inventories are approaching a low point. North American refinery loads have declined, and gasoline cracking profits have strengthened. The premium of reforming oil to RBOB has narrowed, the octane number profit rate of the reforming device has increased, and the refinery's oil - blending efficiency has improved. However, the reforming oil performance reflects that the oil - blending demand has not fully followed up [11][17][29]. 3.3 Aromatic Hydrocarbon Fundamentals Overview - **Aromatic Hydrocarbons**: The supply of xylene has increased, and the weakness of aromatic hydrocarbons has continued. The cross - regional arbitrage space for aromatic hydrocarbons has opened, but physical trade has not occurred. The price of pure benzene continues to suppress the disproportionation profit, and the profit of the STDP device is negative. Some producers have reduced the load of the reforming device due to the average profit of benzene [37][47][62]. - **PX**: It is the core of the price fluctuation in the polyester industry. After the listing of PX futures, its pricing is closely linked to futures. The PX spot trading is active, the price has significantly rebounded, and the profit has been significantly repaired. However, attention should be paid to the sustainability of downstream demand and geopolitical supply disturbances [58][67]. - **PTA**: Due to the large domestic PTA production capacity, the processing interval of PTA has long been maintained below 500 yuan. With the launch of new devices and new production capacities, the option - based income - enhancement scheme is increasingly widely used in the market [58][66]. - **Short Fibers and Bottle Chips**: They are in the production capacity launch cycle. Since the domestic downstream demand is relatively stable, overseas demand has become an important variable. With the implementation of the "Belt and Road" initiative, the industry has found new export opportunities and sales growth points in countries along the "Belt and Road" [58][66]. 3.4 Polyester Fundamentals Overview - **Ethylene Glycol**: The port inventory of ethylene glycol in East China is still at a low level, the port arrivals are still limited, and the import volume of ethylene glycol in the overseas market is expected to decline. New device launches have continuously pressured the ethylene glycol price. The coal price has risen, but it has not provided stronger cost support for ethylene glycol, and the profit of coal - based ethylene glycol has been repaired. The downstream weaving load may remain optimistic [87]. - **Gasoline**: The profit of Asian gasoline has significantly rebounded due to the reduction in domestic exports [89]. - **Polyester**: Polyester continues to maintain a high load, and the weaving load remains optimistic. The production of polyester has rebounded, and attention should be paid to the export performance after the tariff adjustment. The domestic polyester export is still optimistic, but the industry profit is still restricted by the over - capacity caused by new device launches [73][96][98].

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 PTA has a slight contraction, the demand side of polyester is slightly recovering, and the overall market is in an oscillating state. The future trend depends on the recovery of downstream demand and the evolution of global energy and trade policies [3][65]. 3. Summary by Relevant Catalogs 3.1 Main Views and Strategy Overview - **Supply**: The domestic crude oil import is disrupted, and some refineries and trading companies are sanctioned, which may affect the refinery's operation. The supply of domestic PTA devices has a slight contraction, the PTA basis is stable, the PX device operating rate is stable, the cost is strengthening, and the PXN has also expanded [3]. - **Demand**: The downstream load of polyester maintains at about 90%, the inventory of polyester factories is optimistic, and the polyester sales are higher than expected. Whether the weaving can maintain the load in the future needs attention [3]. - **Inventory**: The port inventory of PTA has significantly increased this week, and the physical goods in the Ningbo direction are slightly in short supply [3]. - **Basis**: The PTA basis quickly stabilizes, the PTA profit continues to shrink, and the liquidity of the PTA market is more tense than before [3]. - **Profit**: The price difference between PX and naphtha reaches $250, the processing fee of PTA still maintains at about 200 yuan, and the processing fee of PTA has shrunk [3]. - **Valuation**: The PTA price is at a neutral - low level. After the domestic maintenance season ends, the reforming device gradually recovers. Due to the rise in crude oil prices, the absolute price of PTA follows the rise [3]. - **Macro - policy**: On the morning of October 25 local time, the economic and trade teams of China and the United States began the Sino - US economic and trade consultations in Kuala Lumpur, Malaysia [3]. - **Investment view**: There is no obvious driving factor, and it is expected to be mainly oscillating upwards [3]. - **Trading strategy**: Unilateral: Wait and see. Risk attention: Geopolitical risks [3]. 3.2 Oil Product Fundamentals Overview - **Gasoline demand**: The US government shutdown may affect demand in the off - season. The load of North American refineries has declined, and the gasoline supply has shrunk. The gasoline peak season is over, and the high - octane premium remains [8][14][25]. - **Inventory and price**: The EIA US crude oil inventory, gasoline inventory, and Cushing crude oil inventory are presented in the data. The gasoline cracking profit has increased significantly, and the refined oil price adjustment lags behind that of crude oil [8][9][65]. 3.3 Aromatic Hydrocarbon Fundamentals Overview - **Supply contraction**: Some domestic companies are sanctioned, leading to a contraction in the supply of aromatic hydrocarbons. The mixed xylene market price has strengthened due to the increase in upstream costs, but the market faces the dual pressures of sufficient supply and weak demand [34][56]. - **Arbitrage opportunity**: The cross - regional arbitrage space for aromatic hydrocarbons has opened, but physical trade has not yet occurred. The profit of selective disproportionation has declined, and the pure benzene price suppresses the disproportionation profit [45][51][58]. - **PX, PTA, and short - fiber and bottle - chip markets**: PX is the core of polyester industry price fluctuations, and its pricing is closely linked to futures. The PTA processing interval is long - term maintained below 500 yuan, and the option - based income - enhancement plan is more widely used. Short - fiber and bottle - chip are in the capacity release cycle, and overseas demand is an important variable [55][64]. 3.4 Polyester Fundamentals Overview - **Ethylene glycol**: The supply of ethylene glycol has increased, and the price is running weakly. The port inventory of ethylene glycol in East China is still at a low level, and the new domestic devices put into production have continuously pressured the price [79][85]. - **Polyester operation**: Polyester continues to maintain a high load, and the weaving load performance exceeds expectations. The polyester production has recovered, but the downstream has entered the off - season [94][96].

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. The future domestic xylene capacity will continue to be put into production at a high speed, with 1.7 million tons of xylene devices in Jiujiang Petrochemical, Huajin Aramco, and Zhongsha Gulei waiting to be put into production in 2026 [62] - **Market Situation**: The cross - regional arbitrage space for aromatics has opened, but physical trade has not occurred. The profit of selective disproportionation has declined, and the pure benzene price has suppressed the disproportionation profit. After the end of the maintenance season, the floating spread of PX has continued to weaken, the operating rate has significantly recovered, and the load has reached a very high level [40][54][62] - **Outlook**: Mixed xylene is facing continuous downward pressure. The profit of both gasoline reforming and aromatic hydrocarbon reforming has recovered, but the PTA supply side has shrunk, the processing fee has remained low, and the industry profit is still restricted by over - capacity [52][66] 3.4 Polyester Fundamentals Overview - **Ethylene Glycol**: The supply of ethylene glycol has increased, and the price is running weakly. The inventory in East China ethylene glycol ports is still at a low level, the arrival volume at ports is limited, the import volume in the overseas market is expected to decline, and the new domestic devices have put pressure on the price. The coal - to - ethylene glycol operating rate has continued to recover, and the profit has been repaired [80] - **Gasoline**: The load of major refineries may decline due to port transportation [81] - **Polyester**: Polyester continues to maintain a high load, but the weaving load may decline. The polyester production has increased, and the downstream has entered the off - season [88][90]

1. Report Industry Investment Rating - The investment view for polyester is "oscillating", suggesting a lack of clear driving forces and an expected period of mainly oscillatory movement [4]. 2. Core View of the Report - The polyester market is experiencing a situation where fundamentals and sentiment are in resonance, leading to a decline in the chemical sector, with polyester following suit. Various factors such as supply, demand, inventory, and others are influencing the market, and overall, the market is expected to be mainly oscillatory [4]. 3. Summary by Relevant Catalogs 3.1 Main Views and Strategy Overview - **Supply**: Some ports are responding to sanctions, causing disruptions in China's crude oil imports. The optimization demand for oil products may be better than the chemical demand. For the PTA segment, the domestic PTA device supply has slightly contracted, the PTA basis has stabilized, and the PX device operating rate has been stable. However, due to sentiment disruptions, costs have weakened, and polyester is expected to decline accordingly [4]. - **Demand**: The downstream load of polyester has remained at around 90%. The inventory of polyester factories is optimistic, with the main increase in polyester load concentrated in the bottle - chip variety, and the weaving - end load has remained stable [4]. - **Inventory**: The port inventory of PTA has slightly increased by 50,000 tons, with a small inventory build - up during the holiday [4]. - **Basis**: The PTA basis has quickly stabilized, the PTA profit has continued to shrink, and the liquidity in the PTA market is very loose [4]. - **Profit**: The spread between PX and naphtha has reached $220, and the PTA processing fee has remained at around 200 yuan, with a slight expansion [4]. - **Valuation**: The PTA price is at a moderately low level. After the domestic maintenance season ended, the reforming device has gradually recovered, but attention should be paid to the disruptions to the PX raw material supply caused by the current sanctions [4]. - **Macro Policy**: The State Administration for Market Regulation has launched a legal investigation into Qualcomm for suspected violations of the Anti - Monopoly Law due to its failure to legally report the concentration of business operators in its acquisition of Autotalks [4]. - **Investment View**: There are no obvious driving forces, and the market is expected to mainly oscillate [4]. - **Trading Strategy**: For single - sided trading, it is recommended to wait and see, and attention should be paid to geopolitical risks [4]. 3.2 Oil Product Fundamentals Overview - The market anticipates an oil surplus in the fourth quarter of 2025, with an estimated surplus of 1.7 million barrels per day. In the first quarter of 2026, as OPEC+ increases production, the surplus is expected to further increase to 2.3 million barrels per day. China has been increasing its SPR strategic reserves, adding to the global additional demand for crude oil. Most of the current crude oil increments come from the Middle East, mainly provided by Saudi Arabia and the UAE [24]. - The US government shutdown may affect gasoline demand during the off - season. North American refineries are operating at high loads. As winter approaches and the North American RVP changes, the increasing demand for butane blending may make it difficult to maintain gasoline profits. The change in North American cracking spreads may affect Asian gasoline cracking spreads, and the cracking spreads in major global regions may weaken [50]. 3.3 Aromatic Hydrocarbon Fundamentals Overview - With the commissioning of Yulong Petrochemical's new device, the supply of aromatic hydrocarbons has increased. The profit from selective disproportionation has declined. After the end of the maintenance season, the floating spread of PX has continued to weaken, and the operating rate of PX has significantly recovered [33][63]. - The price of pure benzene is suppressing the disproportionation profit. The supply of MX is expected to increase starting in October, and the future domestic xylene capacity addition will continue at a high rate. In 2026, a total of 1.7 million tons of xylene devices from several companies are waiting to be commissioned [63]. - The processing fee of PTA has remained low, and the industry profit is still restricted by over - capacity due to new device commissioning. The downstream load of polyester has remained above 90%, indicating optimistic market demand. Mainstream PTA factories have planned to reduce production, and the PTA operating rate may further improve, but it is difficult for PTA to have an independent market due to the decline in crude oil prices [70]. 3.4 Polyester Fundamentals Overview - **Ethylene Glycol**: The supply of ethylene glycol has increased, and the price has been weakly operating. The ethylene glycol port inventory in East China is still at a low level, the weekly port arrivals are limited, the overseas import volume of ethylene glycol is expected to decline, and the commissioning of domestic new devices has continuously pressured the ethylene glycol price. The profit of coal - based ethylene glycol has recovered, and the device load has increased [77][83]. - **Gasoline**: The load of major refineries may decline due to port transportation impacts [85]. - **Polyester**: Polyester has continued to maintain a high load, and the production of polyester has increased while the downstream has entered the off - season [91][99].
