Report Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Viewpoints - The crude oil price is expected to show a weak and volatile trend due to the end of the demand peak season, increased inventory accumulation in the US, and concerns about supply disruptions from geopolitical frictions [3]. - The PX price is expected to fluctuate following the crude oil price, with a short - term supply - demand balance. PTA is likely to have a small inventory build - up before the year - end and will mainly follow the cost - end fluctuations [3][7]. - The domestic ethylene glycol (MEG) futures price is expected to run weakly due to factors such as increased supply expectations, weakening cost support, and high inventory [4]. - The prices of pure benzene (BZ) and styrene (EB) may not have sustainable rebounds as their fundamentals have limited positive factors and the cost - end oil price is under pressure [4]. 3. Summary by Product Crude Oil - OPEC+ decided to increase production by 137,000 barrels per day in December and suspend production increases in Q1 2026. The next meeting is on November 30. The demand peak season has ended, and US crude oil inventory accumulation has increased. Geopolitical frictions may limit Russian oil exports and support the oil price. The market consensus on future supply surplus leads to an expected weak and volatile price [3]. PX & PTA - PX: The domestic overall load remains high, with a weekly average domestic capacity utilization rate of 89.21% (-0.36% week - on - week) and an Asian average of 79.79% (+0.06% week - on - week). The PX - naphtha spread is stable at around $250/ton. With limited fourth - quarter maintenance and no new domestic capacity in H1 2026, and positive factors for terminal demand, the supply - demand is stable, and the price is expected to follow the crude oil price [3][7]. - PTA: Two sets of devices were shut down for maintenance this week, with the weekly operating rate dropping to 74.29%. Polyester load remained high, and sales volume increased. Before the implementation of substantial policies, there is an expectation of a small inventory build - up due to increased supply and weak demand before the year - end. The processing margin is still low, and it is expected to follow the cost - end fluctuations [3][13]. MEG - The overall domestic load decreased slightly, but new plant trials increased supply expectations. The cost support from crude oil and coal weakened. Coal - based MEG profit shrank, and the operating rate decreased. After the "Double Eleven", the downstream polyester operating load is expected to decline, and the port inventory has been accumulating. The high inventory will suppress the price, and the price is expected to run weakly [4][18]. BZ & EB - BZ: The domestic load decreased, but the port inventory increased significantly. The import volume is expected to remain high, and downstream profits are generally in deficit. Although the North American blending demand has improved, the overall demand is weak. - EB: The weekly operating rate decreased slightly, with new plant launches and some restarts. There are planned maintenance in the second half of the month. The port inventory decreased, but the expected arrival volume in the second half of the month will increase. The downstream 3S operating rate increased slightly, but the overall inventory is high. The price rebound may not be sustainable [4][26]. Polyester - The average weekly capacity utilization rate of the domestic polyester industry was 87.59% (+0.07% week - on - week). Polyester staple fiber and filament had a small inventory build - up. The comprehensive operating rate of the Jiangsu and Zhejiang chemical fiber weaving industry was 67.69% (-0.30% from the previous period), and the average terminal weaving order days decreased to 13.54 days (-0.95 days). The new order growth is weak, and the market activity has declined [22].

Report Industry Investment Ratings No relevant content provided. Core Views of the Reports Polyolefins - PP shows a pattern of both supply and demand increase, with reduced maintenance leading to increased supply and slight inventory accumulation under new capacity pressure. PE shows increased supply and decreased demand, with abundant imported goods and weak demand except for agricultural film. The cost side has fluctuating crude oil and strong coal, and PDH profits continue to weaken [2]. Crude Oil - The US proposed a new plan to restart the Russia - Ukraine peace negotiation, causing geopolitical premiums to decline and oil prices to fall. OPEC+ is continuously increasing production, and US crude oil production is at a new high, resulting in a weak supply - demand pattern and significant pressure on oil prices. Short - term Brent crude is expected to find support at $60 per barrel [3]. Natural Rubber - Supply: Domestic production areas are entering the production - reducing and cutting - off season, and rainfall in overseas areas keeps raw material prices high. However, the arrival of overseas ships is increasing seasonally, and inventory accumulation suppresses spot prices. Demand: Overall demand is weak, and the market mainly focuses on digesting channel inventory. It is expected that the natural rubber market will enter a range - bound consolidation [5]. Glass and Soda Ash - Soda Ash: The market is in an overall surplus situation. Supply is high, and downstream demand is mainly based on rigid needs. The supply - demand pattern is still bearish, and it is recommended to wait for rebounds to short [7]. - Glass: Recently, prices have been falling, and low prices have driven better sales. However, there are still production line restarts in the future, which will increase supply pressure. In the short term, there is some rigid demand support, but in the long term, demand will shrink, and prices will be under pressure [7]. PVC and Caustic Soda - Caustic Soda: The supply - demand situation is under pressure. The main downstream, alumina, has reduced purchasing enthusiasm. Although there is some supply reduction in the East China region, the long - term supply - demand pressure remains large, and prices are expected to be weak [8]. - PVC: The spot market is in a weak and volatile state. Supply is still at a high level, and demand is in the off - season. The export situation is not optimistic, and the supply - demand surplus pattern continues, with prices expected to remain at the bottom [8]. Polyester Industry Chain - PX: Asian and domestic PX loads have decreased, but supply remains high. Demand is weak, and although there are some supporting factors, the rebound space is limited, and it is expected to be in a high - level shock in the short term [9]. - PTA: After the maintenance of some devices, the basis has strengthened slightly. The supply - demand situation is expected to be relatively balanced in November and more relaxed from December to the first quarter. The rebound space is limited, and it is expected to be in a high - level shock in the short term [9]. - Ethylene Glycol: Domestic supply remains high, and overseas shipments will be concentrated in November, leading to inventory accumulation and a weak basis. It is under pressure above, and corresponding option and spread strategies are recommended [9]. - Short - fiber: Supply remains high, and demand is seasonally weak. The absolute price drive is limited, and processing fees are expected to be compressed [9]. - Bottle - grade PET: Supply changes little, and demand support is insufficient. The supply - demand pattern is loose, and the social inventory is likely to enter the seasonal accumulation period. The processing fee will follow the raw material cost [9]. Methanol - In the inland market, production will continue to increase, and marginal devices are in a loss state. In the port market, Iranian gas restrictions are postponed, and shipments are accelerating, resulting in high inventory and weak prices. The core contradiction is high port inventory, and the "weak reality" logic will continue [10]. Pure Benzene and Styrene - Pure Benzene: Although there are maintenance expectations for some devices, imports are expected to be high, and overall supply may be relatively loose. Demand support is limited, and port inventory is accumulating. The supply pressure is large, and the short - term BZ2603 contract is recommended to be observed [13]. - Styrene: The supply - demand situation has improved, with export expectations and falling port inventory. However, profit recovery may lead to delayed maintenance and new device trials, and downstream EPS demand is expected to weaken, so the upside space is limited [13].

Market Overview - On November 18, PTA futures experienced fluctuations and a slight decline, with the spot market showing a general atmosphere of negotiation. The spot basis strengthened slightly, with limited offers from polyester factories. Transactions for November were reported at a discount of 70-72 for January contracts, with some lower at 75, and the price negotiation range was around 4580-4645 [1] - For December, transactions were noted at a discount of 65 for early December and 55-58 for late December, while November warehouse receipts were traded around 50 [1] Profitability - As of November 18, the PTA spot processing fee was approximately 186 yuan/ton, while the processing fees for TA2601 and TA2603 contracts were 237 yuan/ton and 262 yuan/ton, respectively [2] Supply and Demand - Supply: As of November 14, PTA operating rates were at 75.7%, a decrease of 0.7%. A 2.5 million ton PTA facility in East China was scheduled for maintenance for about a week, and another 2.2 million ton PTA unit in Ningbo was planned for maintenance on November 20 [3] - Demand: By November 14, several bottle chip and filament facilities were under maintenance, leading to a decrease in polyester operating rates to approximately 90.3%, down by 1%. On November 18, the price of polyester filament showed minor adjustments, with overall sales being weak. The gradual lifting of BIS certification restrictions in India has led to increased inquiries from Indian customers, boosting exports of FDY fine denier yarn and resulting in price increases. Current factory inventories are low, and as the peak season comes to an end, short-term prices are expected to remain stable with limited downside [3] Market Outlook - This week, with two PTA facilities in East China undergoing maintenance, the basis has slightly strengthened. The supply-demand balance for PTA in November is tight, but expectations for December and the first quarter of next year lean towards a more relaxed supply-demand situation, limiting upward pressure on the basis. Absolute prices are currently supported by demand for adjusted oil and the cancellation of BIS certification in India, although recent speculative trading in oil has cooled down, and the actual impact of the BIS certification cancellation on exports remains to be seen. Coupled with limited overall support from oil prices, the rebound potential for PTA remains constrained. The strategy suggests that TA will fluctuate within the 4500-4800 range in the short term, with a rolling reverse spread approach [4]
