Report Industry Investment Rating No relevant information provided. Core Viewpoints of the Report - In 2026, PX's new capacity pressure is expected to gradually emerge in the second half of the third quarter. PTA is in a production hiatus, and PX is expected to remain strong in the industrial chain. PTA may have a recovery expectation after its processing fee hits a recent low. The supply - demand pressure for the whole year is not significant. Pay attention to the opportunity for PTA processing fee to recover and the opportunity for the spread between TA - EG to widen on dips [1][163]. - In 2026, ethylene glycol (MEG) faces significant production pressure. Potential capacity and high overseas supply pose risks to the market. Overall, the supply - demand pattern of MEG is weaker than that of PTA. Pay attention to the spread changes [1][163]. - In 2026, due to the continued slowdown of global economic growth, domestic demand is weak and requires more policy support. Exports may continue to be mainly for rigid demand. Despite the pressure on terminal exports, polyester segment exports are still worth looking forward to. The polyester segment will continue to grow steadily. The supply - demand pressure in the staple fiber market is expected to increase, and attention should be paid to the opportunity to protect processing fees at high prices. The new supply pressure of bottle chips in 2026 is not large, but the capacity of existing devices is still high. Overall profit may have an improvement expectation, but the recovery space may not be optimistic [2][164]. Summary According to Relevant Catalogs 1. Market Review - **PTA**: In 2025, PTA reached a high of around 5300 yuan/ton at the beginning of the year. The market price declined due to seasonal inventory accumulation and tariff increases. The new device put into operation in the second half of the year put pressure on the market, and the main contract price fluctuated widely between 4400 - 5000 yuan/ton. Three new devices were put into operation, with a net capacity growth rate of 7.1%, and the cumulative output was expected to be 7390 tons, a year - on - year increase of about 2.8% [19][23]. - **MEG**: In 2025, the futures price of ethylene glycol showed a phased downward trend. Three new devices with a total of 170 tons were put into operation, with a net capacity growth rate of 3.7%. The cumulative output was expected to be 2080 tons, a year - on - year increase of 6.1% [23]. - **Polyester and Terminal**: In 2025, the domestic sales growth of textile and apparel was slow. Exports were volatile, with a significant decline in exports to the US. The polyester segment had good production but poor profits due to raw materials and demand. The cumulative new capacity of polyester in the whole year was expected to be 446 tons, and the cumulative output from January to December was expected to be 7990 tons, with a year - on - year growth rate of about 6.8% [24]. 2. PTA: More Maintenance under Low Processing Fees, with Expectation of Supply - Demand Improvement - **Raw Material End**: From 2024 - 2025, there was no new PX production capacity. The average operating rate in 2025 was 82.8%, and the estimated output was 3.84 billion tons, a year - on - year increase of 1.6%. In 2026, new production capacity is mainly planned to be put into operation in the second half of the year, and PX is expected to remain strong in the industrial chain [30][37]. - **Processing Fee**: In 2025, the average spot processing fee of PTA was only 262 yuan/ton, the lowest in recent years. In the second half of the year, the processing fee fell below 200 yuan/ton, leading to more maintenance [39][45]. - **Export**: In 2025, from January to October, China's PTA exports totaled 3.096 million tons. The cancellation of India's BIS certification is beneficial to exports, but the future new production capacity in India may affect exports [45]. - **2026 Outlook**: There is no new PTA production plan in 2026. The supply - demand situation is expected to improve. Pay attention to the opportunity for PTA processing fees to recover [47]. 3. MEG: Supply Pressure is Prominent - **Actual Supply Increase**: In 2025, the price of ethylene glycol dropped significantly twice, and the end - of - year futures price hit a five - year low. The actual output increased significantly. The proportion of naphtha - based MEG is still about half, and the proportion of coal - based ethylene glycol is about 36% [50]. - **Cash Flow and Operating Rate**: In 2025, the average cash flow of naphtha - based MEG was - 120 US dollars/ton. The overall domestic ethylene glycol operating rate was 70.6%. The coal - based ethylene glycol operating rate was relatively high, and the profit situation improved significantly [64][65]. - **Inventory and Import**: In 2025, the main port inventory first increased and then decreased, and then increased again at the end of the year. From January to October, the import volume was 6.3 million tons, a year - on - year increase of 16.2%. The overseas supply is generally abundant, and imports are expected to remain at a relatively high level [70]. - **Future New Production**: From 2026, the planned production capacity of ethylene glycol will increase again. The future supply - demand pattern is weaker than that of PTA. Pay attention to the spread between PTA - MEG [72][73]. 4. Demand: Polyester Shows Resilience, Pay Attention to Policy Changes in the Terminal - **Polyester Growth**: In 2025, it is expected that a total of 4.46 million tons of new polyester production capacity will be put into operation. The average operating load for the whole year reached 90%. The expected output for the whole year was about 79.8 million tons, a year - on - year increase of 6.8%. In 2026, the planned new polyester production capacity is 5 - 6 million tons, and the output is still expected to reach about 85 million tons [86][100]. - **Staple Fiber**: In 2025, the effective production capacity of direct - spun polyester staple fiber increased by about 4%, and the output increased by 10.1%. The inventory decreased to a low level, and the average operating rate was 91%. In 2026, the supply - demand pressure in the staple fiber market is expected to increase. Pay attention to the opportunity to protect processing fees at high prices [106][122]. - **Bottle Chips**: In 2025, the new production scale of bottle chips narrowed, and the average spot processing fee dropped to a record low of 386 yuan/ton. The inventory pressure was transferred in the third quarter, and the inventory accumulation slowed down in the fourth quarter. In 2026, the new supply pressure is not large, and the profit may improve, but the recovery space may not be optimistic [125][134]. - **Terminal Market**: In 2025, the domestic demand for textile and apparel improved moderately, and exports were affected by international trade. In 2026, domestic demand is weak and requires policy support, and exports may be mainly for rigid demand. Polyester segment exports are still worth looking forward to [141][162]. 5. 2026 Market Outlook and Strategies - **PTA**: In 2026, PX's new capacity pressure is expected to gradually emerge in the second half of the third quarter. PTA may see its processing fee recover, and the supply - demand pressure for the whole year is not significant. Pay attention to the opportunity for PTA processing fee to recover and the opportunity for the spread between TA - EG to widen on dips [1][163]. - **MEG**: In 2026, the production pressure of ethylene glycol is large. The inventory may continue to rise at the beginning of the year, improve in the second quarter, and enter the inventory accumulation cycle again in the third and fourth quarters. The supply - demand pattern is weaker than that of PTA. Pay attention to the spread changes [1][163]. - **Polyester and Terminal**: In 2026, domestic demand is weak and requires policy support. Exports may be mainly for rigid demand. The polyester segment will continue to grow steadily. The supply - demand pressure in the staple fiber market is expected to increase, and the profit of bottle chips may improve, but the recovery space may not be optimistic [2][164].

1. Report Industry Investment Rating - All the analyzed energy and chemical products, including crude oil, fuel oil, asphalt, polyester, rubber, methanol, polyolefins, and polyvinyl chloride, are rated as "volatile" [1][2][4][5][6]. 2. Core Viewpoints of the Report - The supply - side pressure in the crude oil market has replaced geopolitical concerns, leading to a lack of support for oil prices and continuous price declines. Other energy and chemical products are also affected by factors such as supply - demand relationships, cost changes, and seasonal demand fluctuations, and their prices are expected to fluctuate [1][2][4]. 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Monday, the price of WTI January contract closed down $0.62 to $56.82 per barrel, a decline of 1.08%. The Brent February contract closed down $0.56 to $60.56 per barrel, a decline of 0.92%. SC2601 closed at 430.2 yuan per barrel, down 6.9 yuan per barrel, a decline of 1.58%. In November, the output and processing volume of industrial crude oil above designated size increased year - on - year. Kazakhstan increased oil supply to Kyrgyzstan and Uzbekistan, and the delivery of new mooring points at the Caspian Pipeline Consortium's Black Sea terminal was advanced. The supply - side pressure led to a continuous decline in oil prices [1]. - **Fuel Oil**: On Monday, the main fuel oil contract FU2601 on the Shanghai Futures Exchange rose 2.11% to 2417 yuan per ton, and the low - sulfur fuel oil contract LU2602 rose 1.08% to 3005 yuan per ton. The high - and low - sulfur fuel oil markets are under pressure due to sufficient supply. Although the arbitrage arrivals from the Western market in Singapore are expected to decrease in December, the inventory in November increased significantly, and the supply from the Middle East in recent weeks has been substantial. The demand for marine bunkering is relatively stable, and the decline in high - sulfur fuel oil cracking profits may boost the demand of Asian refineries for high - sulfur fuel oil raw materials in the future [2]. - **Asphalt**: On Monday, the main asphalt contract BU2602 on the Shanghai Futures Exchange rose 0.54% to 2963 yuan per ton. Tensions between the US and Venezuela have led to concerns about future raw material shortages, making the market relatively firm. Currently, refinery raw materials are relatively sufficient, and the downstream demand for asphalt in China shows significant north - south differentiation. It is expected that asphalt may remain stable in the short term under the weak oil price, but there is also a possibility of price decline [2]. - **Polyester**: TA601 closed at 4696 yuan per ton on Monday, up 1.78%. EG2601 closed at 3651 yuan per ton, up 0.66%. The inventory of MEG in the East China main port area increased by 2.5 tons to about 84.4 tons on December 15. A 260,000 - ton PX device in Japan restarted as planned. The cost - side oil price decline and the seasonal weakening of terminal demand will drag down prices. Some ethylene glycol devices are in a loss state and have stopped for maintenance, but new devices are in the production - preparation stage, increasing supply pressure [4]. - **Rubber**: On Monday, the main natural rubber contract RU2605 fell 30 yuan per ton to 15200 yuan per ton, and the NR contract rose 30 yuan per ton to 12360 yuan per ton. In the first three quarters of 2025, the cumulative number of tire imports in the US increased by 6.6% year - on - year. The inventory of natural rubber in Qingdao increased. The weather in overseas production areas has improved, and raw material prices have rebounded. It is expected that rubber futures prices will fluctuate widely [4][5]. - **Methanol**: On Monday, the spot price in Taicang was 2105 yuan per ton. The supply of domestic methanol is at a high - level volatility, and the supply from Iran is expected to decline. The demand from the olefin sector is expected to weaken. Although the inventory has decreased significantly in the short term, there may be a rebound later. It is expected that methanol prices will remain at the bottom and fluctuate [5]. - **Polyolefins**: On Monday, the mainstream price of East China拉丝 was between 6170 - 6400 yuan per ton. The production of polyolefins will remain at a high level, while downstream orders and production starts will gradually weaken. It is expected that polyolefins will gradually shift to a situation of strong supply and weak demand, but the short - term decline space of futures is limited, and prices are expected to fluctuate at the bottom [6]. - **Polyvinyl Chloride**: On Monday, the market price of PVC in East, North, and South China increased. The supply of PVC has decreased in routine maintenance this week but increased in sudden production cuts. The production is expected to increase slightly next week.

1. Report Industry Investment Rating - Not provided in the document. 2. Core Views of the Report - For crude oil, although geopolitical premiums have disappeared and OPEC's production increase is minimal with supply not yet surging, short - term oil prices should not be overly bearish. A range - trading strategy of buying low and selling high is maintained, but it's recommended to wait and see for now to verify OPEC's export - price support willingness [3]. - For methanol, after the bullish factors are realized, the market will enter a short - term consolidation. With high import arrivals and expected port olefin plant maintenance, there is still pressure on the port. The supply is at a high level, and the market is expected to consolidate at a low level. It's recommended to wait and see [6]. - For urea, the market is oscillating higher. With improved demand and expected seasonal decline in supply, the overall supply - demand situation has improved. There is support from export policies and costs, and it's recommended to consider buying at low prices [9][10]. - For rubber, a neutral approach is taken, suggesting short - term operations and holding a hedging position of buying RU2601 and selling RU2609 [12]. - For PVC, the industry has low comprehensive profits, but high supply and weak domestic demand. It is recommended to take a short - selling approach on rallies in the medium term [16]. - For pure benzene and styrene, the non - integrated profit of styrene has room for upward repair. It's possible to go long on the non - integrated profit of styrene before the first quarter of next year [19]. - For polyethylene, the price of crude oil may have bottomed out, but high - level warehouse receipts suppress the market. It's recommended to short the LL1 - 5 spread on rallies [22]. - For polypropylene, in a situation of weak supply and demand with high inventory pressure, the market may be supported when the supply - surplus pattern of the cost side changes in the first quarter of next year [25]. - For PX, it is expected to have a slight inventory build - up in December. It is recommended to look for opportunities to go long on dips [28]. - For PTA, the supply is expected to increase and the demand will decline due to the off - season. It is recommended to look for opportunities to go long on dips based on expectations [31]. - For ethylene glycol, the supply is expected to improve but the inventory build - up cycle will continue. There is a risk of a rebound due to unexpected maintenance [33]. 3.

1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - The PTA market declined slightly, and it was still in a state of destocking, with a slight increase in the spot basis. The gasoline cracking profit of PTA declined, and the PX - naphtha spread widened to $252, reflecting raw material cost pressure, but the PX - benzene spread only slightly increased to $210, weakening the overall profit of the combined aromatics unit. The polyester new device put into production kept the polyester load at a high level, and the PTA consumption was close to the historical high in May. The cancellation of the Indian BIS certification was expected to drive an increase in exports [2]. - The ethylene glycol futures maintained low - level volatile trading, and the spot price in Zhangjiagang adjusted slightly, with the basis negotiation weakening. The ethylene glycol price was difficult to get effective support due to the continuous decline of coal prices, and the market supply pressure continued to increase with the new devices being put into production. The increase in polyester export inquiries was expected to boost the export demand of textile and clothing, supporting the downstream weaving sector to maintain a high load [2]. 3.

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - For crude oil, although the geopolitical premium has dissipated and OPEC's production increase is minimal with supply not yet surging, oil prices should not be overly shorted in the short - term. A low - buy and high - sell range strategy is maintained, but it's advisable to wait and see for now to test OPEC's export price - support willingness [2]. - For methanol, after the bullish factors are realized, the market enters short - term consolidation. With high import arrivals and expected port olefin plant maintenance, there is still pressure on the port. The supply is at a high level, and the market is expected to consolidate at a low level. A wait - and - see approach is recommended for single - side trading [3]. - For urea, the market is rising in a volatile manner. Demand has improved in the short - term due to reserve needs and increased compound fertilizer production. Supply is expected to decline seasonally. With export policy and cost support, the downside space is limited, and it is expected to build a bottom in a volatile manner. Buying on dips is recommended [6]. - For rubber, a neutral approach is taken, suggesting short - term operations. Holding a hedging position of buying RU2601 and selling RU2609 is advised [12]. - For PVC, the enterprise's comprehensive profit is at a historical low, but supply reduction is limited, and demand is under pressure. With strong supply and weak demand in the domestic market, shorting on rallies is recommended before significant industry production cuts [13][15]. - For pure benzene and styrene, when the inventory reversal point appears, going long on the non - integrated profit of styrene can be considered. Currently, styrene's non - integrated profit is neutral to low, with potential for upward valuation repair [18]. - For polyethylene, OPEC +'s plan to suspend production growth in Q1 2026 may lead to a bottoming of oil prices. With high inventory and seasonal demand decline, shorting the LL1 - 5 spread on rallies is recommended [21]. - For polypropylene, with expected supply surplus in the cost side and high inventory pressure, the market may be supported when the supply - surplus pattern changes in Q1 next year [24]. - For PX, it is expected to slightly accumulate inventory in December. With a neutral valuation, opportunities for going long on dips can be considered [27]. - For PTA, supply maintenance is expected to decrease, and demand will decline due to the off - season. With limited upside for processing fees, opportunities for going long on expected trading can be watched [29]. - For ethylene glycol, although domestic supply has improved due to unexpected maintenance, overall load is still high, and ports are in a inventory - accumulation cycle. Attention should be paid to the risk of a rebound caused by increased maintenance [31].
