1. Report Industry Investment Ratings No information provided in the reports. 2. Core Views of the Reports Polyester Industry Chain - PX: In November, with few PX unit overhauls in Asia and China, but concentrated PTA unit overhauls, PX supply - demand is expected to be weak. PX absolute prices are expected to gradually face pressure. The strategy is to follow crude oil for unilateral trading and go short on rallies, and try to shrink the PX - SC spread [1]. - PTA: In November, there are still many PTA unit overhaul plans. With better - than - expected terminal and polyester demand in October and low polyester inventory, PTA supply - demand is expected to be slightly loose with a small inventory accumulation expectation. PTA will continue to oscillate at a low level. The strategy is to follow crude oil for unilateral trading and go short on rallies, and treat TA1 - 5 as a rolling reverse spread [1]. - Ethylene Glycol (MEG): In November, domestic supply is high, overseas shipments are concentrated, and inventory accumulation is expected to be high, putting pressure on the price. The strategy is to sell out - of - the - money call options on rallies and do a reverse spread on EG1 - 5 on rallies [1]. - Short Fiber: In November, supply is expected to remain high, demand may weaken seasonally, and cost support is limited. Short - fiber prices will gradually face pressure. The strategy is similar to PTA for PF12, and try to shrink the PF processing margin when it is above 1000 [1]. - Bottle Chips: In November, supply changes little, demand is in the off - season, and the supply - demand pattern remains loose. Bottle - chip prices will follow the cost side, and the processing margin will fluctuate with raw material costs. The strategy is similar to PTA for PR, and the main - contract processing margin is expected to fluctuate between 300 - 450 yuan/ton [1]. Chlor - Alkali Industry - Caustic Soda: In November, supply is expected to increase, demand support is weak, and prices are expected to be weakly stable. The overall trend is bearish, and it is necessary to track downstream restocking rhythm [2]. - PVC: In October, PVC prices continued to decline. In November - December, supply pressure will continue due to new capacity and high - season operation, and demand is in the off - season. Prices are expected to continue to oscillate at the bottom [2]. Methanol Industry The current market is trading the "weak reality" logic centered on high port inventory. Before the Iranian gas restriction, the weak reality will continue to be priced in. The 01 - contract inventory problem cannot be solved [3][4][5]. Pure Benzene - Styrene Industry - Pure Benzene: In November, supply is expected to be loose, demand support is limited, and although the East China port inventory decreased in October, it may increase later. Pure - benzene prices are expected to have weak driving force, but attention should be paid to unit changes [8]. - Styrene: In November, supply may slightly decrease, demand is expected to change little, and the supply - demand may be in a tight - balance state. However, high port inventory will limit price increases. The strategy is to be bearish on EB12 price rebounds [8]. Polyolefin Industry PP supply recovery has slowed down due to unplanned overhauls, while PE supply is expected to increase. Demand has recovered, but the agricultural film peak is approaching. Overall, supply will increase and demand will decrease, and there is inventory pressure on the 01 - contract. The 05 - contract may have long - term low - buying opportunities, and the monthly spread is suitable for reverse spreads [10]. 3.

Report Industry Investment Ratings No relevant information provided. Core Views PVC and Caustic Soda - Caustic soda: Supply is at a high level, with weak demand support in the short - term due to shrinking industry profits in downstream alumina. However, there may be demand support in the medium - to long - term as the procurement cycle approaches and alumina has more planned production in Q1 next year [1]. - PVC: Supply returns to a high level as some maintenance enterprises resume production. Domestic downstream demand remains weak, and cost provides bottom - line support. The market is expected to be lackluster during the peak season [1]. Polyester Industry - PX: Supply is generally stable, and demand support has strengthened. It is in a situation of high short - term supply and demand but with a weak overall outlook. Cost support is limited, and the rebound space is restricted [2]. - PTA: Spot basis is weak, and the rebound is expected to face pressure due to factors such as the resumption of some device loads and the decline in oil prices [2]. - MEG: Port inventory decreases, but the upward driving force weakens. The far - month supply - demand structure is weak, and there is significant upward pressure [2]. - Short - fiber: Supply remains high, and demand has improved slightly, but the overall supply - demand drive is limited.

Report Title - The report is titled "Polyester: Favorable Tariff Policy Expected to Boost the Market" [1] Industry Investment Rating - No investment rating for the industry is provided in the report Core Viewpoint - The tariff policy is favorable, which is expected to boost the polyester market. Trade friction alleviation and potential policy support are likely to drive market improvement, though some segments face supply - related challenges [4][7][10] Summary by Catalog PX - PX processing fees are relatively strong. Due to sanctions on Russia by Europe and the US, some domestic refineries are worried, but PX supply is abundant as some plants are set to restart. PX - N is currently at $247/ton, nearly $30 higher than early October. The short - process processing range has also increased, and PX开工意愿 is strong, fluctuating with oil prices [5] PTA - There is a large potential supply pressure. New installations have increased PTA capacity by 10% compared to the end of last year. Although some plants are under maintenance in November, the supply increase pressure is just postponed. November is near the supply - demand balance, but the inventory accumulation expectation increases from December. The PTA processing fee is low, and it may continue to rebound with the support of the tariff policy, but the rebound strength is not optimistic [6] MEG - Domestic supply is at a high level in recent years. Coal - to - MEG load has reached a record high of 83%. Multiple new installations are scheduled to start production, increasing the long - term supply pressure. Import volume is expected to remain high in the fourth quarter. Current port inventory is around 500,000 tons, and the visible inventory will increase. MEG is trading sideways at a low level but may rebound under tariff policy support [8] Terminal Demand - Affected by cooling and "Double Eleven" orders, the starting rate of Jiangsu and Zhejiang looms has reached a high of 76% this year, but it is 6% lower than the same period last year. Polyester product inventories have decreased, and polyester load is expected to remain between 90% - 91% in November. The cancellation of the "fentanyl tariff" and the suspension of the 24% counter - tariff are expected to improve the terminal export market [7][10] Short - fiber - The short - fiber starting rate has slightly increased to around 95.5%. Factory inventories are at a low level, and the processing fee has slightly decreased to around 1,100 yuan/ton. Downstream pure - polyester yarn factories' starting rate is 73%, and product inventories have slightly decreased. With the support of the tariff policy, demand may improve significantly, and the processing fee is not expected to be pessimistic, with the absolute price fluctuating strongly [13] Bottle - chip - From January to September 2025, domestic demand was 7.357 million tons, a year - on - year increase of 6.8%, and exports were 4.809 million tons, a year - on - year increase of 14%. The profitability of bottle - chips has improved but has declined recently. With new installations planned to start production and the expected seasonal decline in the soft - drink market, the market pressure remains, and the processing fee increase space is limited. However, the absolute price may rebound with raw materials under the tariff policy [14]

Group 1: Report Industry Investment Rating - No relevant content provided. Group 2: Core Viewpoints of the Report - PTA prices rapidly declined due to no clear news of "anti-involution" in the PTA industry. Despite the continuous recovery of crude oil prices, PTA prices only rebounded slightly before. Although the overall load of domestic PTA plants decreased due to low processing fees, the polyester industry's profits were still constrained by overcapacity pressure caused by new production capacity and the commissioning of overseas plants. With the cost support provided by rising crude oil prices, PTA prices rebounded rapidly after a long period of low - level operation. The current downstream polyester operating rate remained above 91%, with demand slightly exceeding expectations and recent polyester sales generally high. Also, with positive news from China - US economic and trade negotiations, the market sold on positive news [2]. Group 3: Summary of Data Changes Spot and Futures Prices - PTA spot price remained unchanged at 4535, MEG inner - market price decreased by 5 to 4147. PTA closing price dropped by 66 to 4570, and MEG closing price decreased by 68 to 4032 [2]. Short - fiber - related Data - 1.4D direct - spinning polyester staple fiber price decreased by 10 to 6430, short - fiber basis decreased by 11 to 140, 11 - 12 spread increased by 8 to 28, and polyester staple fiber cash flow increased by 6 to 246. The price difference between 1.4D direct - spinning and imitation large - chemical fiber decreased by 10 to 1030 [2]. Bottle - chip - related Data - Polyester bottle - chip prices in the Jiangsu and Zhejiang markets decreased, with the average price down 5 yuan/ton. The processing fee for bottle - chip spot decreased by 7.33 to 447 [2]. Yarn - related Data - T32S pure - polyester yarn price remained unchanged at 10320, and its processing fee increased by 10 to 3890. The price of polyester - cotton yarn 65/35 45S remained unchanged at 16300, and its profit increased by 2.85 to 1539 [2]. Other Fiber - related Data - The price of primary three - dimensional hollow (with silicon) fiber increased by 15 to 7010, and the cash flow of hollow staple fiber 6 - 15D increased by 16.68 to 543.

Group 1: Investment Rating - No investment rating information is provided in the report. Group 2: Core View - PTA prices quickly declined due to the lack of clear news on the "anti - involution" in the PTA industry. Although crude oil prices have been rising, PTA prices only rebounded slightly before. The polyester industry's profit is under pressure from over - capacity caused by new domestic and overseas installations. With cost support from rising crude oil prices and policy - expectation stimulus, PTA prices rebounded rapidly after long - term low - level operation. The downstream polyester operating rate remains above 91%, and recent polyester sales are relatively high. [2] - The inventory of ethylene glycol (MEG) at East China ports is still low, with limited weekly arrivals. Overseas imports of MEG are expected to decline, while domestic installations are putting pressure on prices. Coal - based MEG installations are also resuming. The overall polyester inventory is in good condition, and the downstream weaving load is maintained. However, as the polyester peak season is ending and the crude oil fundamentals are weakening, the polyester market is expected to operate weakly. [2] Group 3: Summary by Related Catalogs 1.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The oil price is expected to continue oscillating. The uncertainty in the crude oil market lies in the supply - side structural contradictions caused by sanctions, but during the current off - season of demand, the overall conflict is not obvious, and the impact on prices is relatively mild [1]. - The absolute prices of fuel oil (FU and LU), asphalt (BU), polyester, rubber, methanol, polyolefins, and polyvinyl chloride are all expected to oscillate, with attention paid to the fluctuations of oil prices under the influence of macro - factors [3][5][6]. 3. Summary According to Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Thursday, the WTI December contract rose 0.09 dollars to 60.57 dollars/barrel (0.15% increase), the Brent December contract rose 0.08 dollars to 65.00 dollars/barrel (0.12% increase), and the SC2512 closed at 461.4 yuan/barrel, down 1.1 yuan/barrel (0.28% decrease). The meeting between Chinese and US leaders and trade achievements have positive impacts, but sanctions on Russian producers and potential OPEC+ production increase add uncertainties [1]. - **Fuel Oil**: On Thursday, the main contract of high - sulfur fuel oil (FU2601) fell 1.43% to 2751 yuan/ton, and the main contract of low - sulfur fuel oil (LU2601) rose 0.62% to 3255 yuan/ton. The Asian low - sulfur market structure has weakened due to weak downstream demand and sufficient supply, while the high - sulfur market is expected to remain stable [3]. - **Asphalt**: On Thursday, the main contract of asphalt (BU2601) fell 0.4% to 3254 yuan/ton. The supply pressure will ease in early November, and there are still construction rush expectations in some markets [3]. - **Polyester**: TA601 closed at 4570 yuan/ton, down 1.42%; EG2601 closed at 4032 yuan/ton, down 1.66%. The cost support of PX and TA has weakened, and the production and sales of polyester yarn are weak. There is still a pressure of inventory accumulation for EG in the fourth quarter [5]. - **Rubber**: On Thursday, the main contract of natural rubber (RU2601) fell 225 yuan/ton to 15400 yuan/ton, and the main contract of 20 - number rubber (NR) fell 195 yuan/ton to 12525 yuan/ton. The raw material prices of rubber are firm, demand is okay, and the postponement of tariff increase may improve demand expectations [5]. - **Methanol**: The supply in the domestic market has recovered to a high level, and overseas Iranian plants will be restricted by winter gas rationing. Although the arrival volume has decreased due to sanctions, the short - term port supply is still relatively large, and methanol is expected to oscillate [6]. - **Polyolefins**: The short - term production will remain at a high level, and the marginal increase in demand will gradually decline. The short - term rebound of crude oil supports the valuation, but the fundamental driving force is weakening, and polyolefin prices are expected to enter an oscillatory phase [6]. - **Polyvinyl Chloride**: The supply remains at a high - level oscillation, domestic demand has slowed down, and exports are expected to be weak due to Indian anti - dumping policies and Sino - US trade frictions. The price has a demand for phased repair, but the rebound height is limited under high - inventory pressure [8]. 3.2 Daily Data Monitoring - The table shows the spot prices, futures prices, basis, basis rates, and their changes of various energy and chemical products on October 30 and 29, 2025, as well as the quantiles of the latest basis rates in historical data [10]. 3.3 Market News - The meeting between Chinese President Xi Jinping and US President Donald Trump in Busan, South Korea, and the positive results of Sino - US economic and trade consultations have alleviated concerns about the decline in economic activities caused by tariffs and trade wars [13]. - Some Indian refiners have suspended purchasing Russian oil after the US blacklisted two major Russian producers last week, but Indian Oil said it would "never stop" buying Russian crude. Traders are closely watching the next moves of Russian oil buyers [13]. 3.4 Chart Analysis - **4.1 Main Contract Prices**: There are charts showing the closing prices of main contracts of various energy and chemical products from 2021 - 2025, including crude oil, fuel oil, asphalt, etc. [15][16][17]. - **4.2 Main Contract Basis**: There are charts presenting the basis of main contracts of various products such as crude oil, fuel oil, etc., over different time periods [33][38][40]. - **4.3 Inter - period Contract Spreads**: There are charts showing the spreads between different contracts of products like fuel oil, asphalt, etc. [48][50][53]. - **4.4 Inter - variety Spreads**: There are charts depicting the spreads between different varieties such as crude oil internal and external markets, fuel oil high - and low - sulfur spreads, etc. [63][66][71]. - **4.5 Production Profits**: There are charts showing the production profits of products like LLDPE and PP [72]. 3.5 Team Member Introduction - The research team members include Zhong Meiyan (Assistant Director and Energy - Chemical Director), Du Bingqin (Analyst for Crude Oil, etc.), Di Yilin (Analyst for Natural Rubber, etc.), and Peng Haibo (Analyst for Methanol, etc.), with their respective educational backgrounds, honors, and professional capabilities introduced [77][78][79]. 3.6 Contact Information - The company is located at Unit 703, 6th Floor, No. 729 Yanggao South Road, China (Shanghai) Pilot Free Trade Zone.

Report Industry Investment Ratings No relevant content provided. Core Views of the Report PVC and Caustic Soda - The caustic soda market has weak demand support in the short - term due to high supply, low downstream alumina prices, and shrinking industry profits. However, there may be support in the medium - to long - term as the demand procurement cycle approaches and there may be concentrated stocking in the fourth quarter and more alumina production in the first quarter of next year [1]. - The PVC market is expected to continue the logic of a lackluster peak season. The supply has returned to a high level as some maintenance enterprises resumed production this week, while domestic downstream demand remains low, and the cost side provides only bottom - line support [1]. Polyester Industry - For PX, the short - term supply is stable with some plant overhauls offset by toluene and xylene supplements. The demand has strengthened slightly but the overall expectation is weak, and the cost support from oil prices is limited [2]. - For PTA, the spot basis is weak due to increased device loads and new production, and the expected rebound is under pressure [2]. - For ethylene glycol, the upward momentum is weakening due to port inventory changes, refinery maintenance, and falling oil prices. The far - month supply - demand structure is weak, and there is significant upward pressure [2]. - For short - fiber, the supply is high, the demand has improved marginally but the downstream's willingness to chase price increases is low. The cost support is limited, and the price is expected to face pressure in the rebound, although it is relatively stronger than raw materials due to low inventory [2]. - For bottle - chips, the demand is in the traditional off - season, and it is likely to enter a seasonal inventory accumulation period. The price mainly follows the cost side, and the processing fee is expected to fluctuate within a certain range [2]. Pure Benzene and Styrene - The supply of pure benzene in China is abundant with device restarts and new capacity expectations. The demand support is limited as most downstream products are in the red and some secondary - downstream inventories are high. The overall supply - demand expectation is loose, and the price drive is limited [5]. - Styrene is under pressure from inventory and industry profits. Although there are more planned and unplanned device shutdowns, new production from some plants maintains supply pressure. The demand support is limited as downstream industries mainly make rigid purchases due to high finished - product inventories. The supply - demand pattern remains weak, and the rebound is expected to face pressure [5]. Methanol - The port methanol market is under significant pressure due to high inventory and weak demand, resulting in a decline in both price and basis. The inland market has weak sales as producers offer discounts and downstream buyers are hesitant. The demand side is weak as multiple MTO units reduce loads and plan more maintenance. The short - term price is expected to continue to decline, and attention should be paid to port inventory reduction and overseas gas restriction expectations [7][8]. Polyolefins - For PP, the supply recovery is slow due to more unplanned maintenance. For PE, the maintenance is peaking, and the supply is expected to increase. The demand side has improved with rising downstream operating rates, especially in the agricultural film sector. Both inventories are decreasing. The 01 contract still has inventory pressure, while the 05 contract may offer long - term low - buying opportunities [10].
