1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - The polyolefin market continues to operate weakly at the bottom due to the combined effects of supply recovery, the demand entering the off - season inventory digestion cycle, and the spread of market pessimism [4] 3. Summary by Relevant Catalogs 3.1 Market Review and Outlook - The L2605 contract of linear low - density polyethylene (LLDPE) opened lower, fluctuated downward during the session, and closed down at 6,240 yuan/ton, a decrease of 152 yuan/ton (-2.38%), with a turnover of 669,000 lots and an increase of 7,828 lots in positions to 606,042 lots. The PP2605 contract of polypropylene (PP) closed at 6,119 yuan/ton, a decrease of 113 yuan (-1.81%), with an increase of 13,800 lots in positions to 547,800 lots [3][4] - As the device maintenance losses in December decreased significantly month - on - month and the previously shut - down devices restarted one after another, the market supply pressure increased month - on - month. The demand side was restricted by the seasonal off - season, showing obvious weakness. The downstream load of PE mostly declined, and although the PP operating rate remained basically stable, factories mainly digested their previously purchased inventories, with a low willingness to make new purchases [4] - The decline in futures prices directly suppressed spot prices and market sentiment. Some producers lowered their factory prices, and traders' quotes generally followed suit. However, downstream factories lacked confidence in entering the market and mostly adopted a cautious and wait - and - see attitude [4] 3.2 Industry News - On December 22, 2025, the inventory level of major producers was 720,000 tons, an increase of 60,000 tons (9.09%) from the previous working day, compared with 650,000 tons in the same period last year [5] - PE market prices continued to decline. The price of LLDPE in North China was 6,250 - 6,600 yuan/ton, in East China was 6,280 - 6,800 yuan/ton, and in South China was 6,300 - 6,600 yuan/ton [5] - The mainstream price of propylene in the Shandong market was temporarily quoted at 5,870 - 5,900 yuan/ton, a decrease of 30 yuan/ton from the previous working day. Some polypropylene plants were still shut down, and there was still external sales of propylene as a raw material. The demand support for propylene was insufficient, and the overall market supply was loose. Producers further offered price concessions [5] - The center of the PP market moved down. The mainstream price of drawn PP in North China was 5,920 - 6,100 yuan/ton, in East China was 6,000 - 6,200 yuan/ton, and in South China was 6,090 - 6,300 yuan/ton [5]

1. Report's Industry Investment Rating - All the energy - chemical products covered in the report, including crude oil, fuel oil, asphalt, polyester, rubber, methanol, polyolefin, and polyvinyl chloride, are rated as "volatile" [1][2] 2. Report's Core View - On Monday, the price center of crude oil shifted upwards, with WTI February contract rising by $1.49 to $58.01 per barrel (2.64% increase), Brent February contract rising by $1.60 to $62.07 per barrel (2.65% increase), and SC2601 closing at 439.7 yuan per barrel (1.71% increase). China's crude oil imports in November 2025 were 50.891 million tons, with a month - on - month increase of 5.2% and a year - on - year increase of 4.9%. The geopolitical situation has heated up, pushing up oil prices [1]. - The fuel oil market showed an increase on Monday. The low - sulfur fuel oil market structure strengthened slightly, and the high - sulfur fuel oil market also had some support. The supply of low - sulfur fuel oil from the Western market is expected to decline in December and may rebound in January. The high - sulfur fuel oil market is supported by downstream demand [2]. - The asphalt price increased on Monday. Affected by the tense relationship between the US and Venezuela, the cost - side support is strong, but the terminal demand is weak. Considering the limited supply increase and low factory inventory, the downward price space is limited [2]. - In the polyester market, TA605 rose by 3.24% and EG2605 fell by 0.08%. Some MEG and PTA devices have restarted or are expected to restart. The demand is in the off - season, and although the upstream has good expectations for the 2026 supply - demand pattern, the terminal demand support for prices is limited [2][4]. - In the rubber market, on Monday, the main contract of natural rubber showed a mixed trend. The inventory in Qingdao increased. Domestic rubber production has entered the off - cutting period, overseas raw materials are expected to increase, and downstream demand weakens at the end of the year, so the rubber price is expected to fluctuate [4][6]. - The methanol market showed a bottom - oscillating trend. The supply of domestic overhaul devices is stable at a high level, and the Iranian supply remains low. The demand of MTO devices is expected to weaken, and the inventory may fluctuate in the future [6]. - The polyolefin market is expected to show a weak - oscillating trend. The production will remain at a high level, and the downstream orders and start - up rate are weakening [6]. - The PVC market is expected to be at the bottom and oscillate. The supply is expected to decline slightly, and domestic demand will slow down as the real estate construction slows down [8]. 3. Summary According to Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Monday, oil prices rose, and China's crude oil imports increased. The geopolitical situation, including the Russia - Ukraine issue and the US - Venezuela issue, has an impact on oil prices, and the short - term rhythm needs attention [1]. - **Fuel Oil**: The prices of the main contracts of high - sulfur and low - sulfur fuel oil increased. The low - sulfur fuel oil supply may change, and the high - sulfur fuel oil is supported by demand. The absolute price may follow the oil price, and the cracking spread may remain stable and rise [2]. - **Asphalt**: The asphalt price increased. The cost - side is supported by geopolitics, but the terminal demand is weak. Considering supply and inventory, the downward space is limited, and it may follow the oil price [2]. - **Polyester**: The price of TA605 rose, and EG2605 fell slightly. Some devices have restarted, the demand is in the off - season, and the price of PX and TA may rebound in the short - term with limited space, while the upward pressure on the ethylene glycol price is high [2][4]. - **Rubber**: The prices of different rubber varieties showed a mixed trend. The inventory in Qingdao increased, and considering production and demand, the rubber price is expected to oscillate [4][6]. - **Methanol**: The methanol price is expected to oscillate at the bottom. Domestic supply is stable at a high level, Iranian supply is low, MTO demand weakens, and inventory may fluctuate [6]. - **Polyolefin**: The polyolefin market is expected to be weak and oscillating. Production remains high, and downstream demand weakens [6]. - **Polyvinyl Chloride**: The PVC price is expected to oscillate at the bottom.

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports - **Natural Rubber**: With geopolitical tensions affecting supply in Thailand and domestic产区 entering the off - season, there is support at the bottom of rubber prices. However, due to high production and sales pressure and the seasonal demand slump, the market is weak. Rubber prices are expected to fluctuate widely between 15,000 - 15,500 yuan/ton [1]. - **Glass and Soda Ash**: For soda ash, the supply may increase with the potential output from new projects, and demand is shrinking, so the price is expected to continue to decline with occasional technical rebounds. For glass, the spot price is stable but facing weakening demand in the north and high inventory in the middle - stream, so the futures price may be under pressure and continue to oscillate at the bottom [3]. - **PVC and Caustic Soda**: The caustic soda industry still has supply - demand pressure, and prices are expected to be weak. The PVC market is affected by high supply, low demand, and cost pressure, and is expected to maintain range - bound trading and then weaken after a rebound [4]. - **Polyolefins**: The market is trading on the expectation of high production in 2026 and weak current conditions. Both PE and PP are facing downward pressure on prices, with the price center expected to decline further [6]. - **Methanol**: Although the port may face inventory accumulation in December, there is an expected shift to inventory reduction in the first quarter of the next year. The inland market is expected to be stable with prices fluctuating slightly [10]. - **Pure Benzene and Styrene**: The short - term driving force for pure benzene is weak due to weak downstream demand and cost support, but there is an expectation of improvement after the spring maintenance. Styrene is expected to oscillate between 6300 - 6700 yuan/ton due to sufficient supply and weak cost support [13]. - **LPG**: The LPG market shows a pattern of stable prices, inventory reduction, and some improvement in downstream demand. The price is expected to be relatively stable with some fluctuations [15]. - **Polyester Industry Chain**: For PX, it may continue to be strong unless there is substantial production reduction in the polyester sector. PTA is expected to follow the raw material price with limited independent movement. MEG is expected to oscillate at a low level. Short - fiber prices follow the raw material, and the processing fee of bottle - chips is expected to be compressed [17]. - **Crude Oil**: The market is dominated by geopolitical factors. With high supply and weak demand, the price is expected to oscillate, and attention should be paid to the price of Brent crude at $60 per barrel [18]. - **Urea**: The futures price is weak, while the spot price is rising. The Indian tender is beneficial for exports, but high supply and weak demand in the domestic market lead to a difficult price trend. The futures price is expected to oscillate between 1680 - 1730 yuan/ton [20]. 3.

1. Report Industry Investment Rating There is no information provided in the report regarding the industry investment rating. 2. Core Viewpoints of the Report - For plastics, the supply - demand drive is weak, and the current LLDPE weighted profit is at a low level in the same period but still has room to decline. With the end of the peak season for northern shed films and the anti - seasonal inventory accumulation, there is high pressure on destocking. High - production cycles combined with seasonal weakening of supply and demand suggest that previous short positions can be held, and some can be reduced [4]. - For PP, attention should be paid to the dynamics of PDH devices. Although the weighted profit has room to decline, the marginal device PDH profit has limited room for further compression, increasing the expectation of maintenance. Given the high inventory, previous short positions can be held, and some can be closed at low prices [8]. 3. Summary by Relevant Catalogs Plastics Market Review - This week, plastics opened flat and closed lower, with three consecutive negative weekly lines.

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Although the geopolitical premium has completely dissipated and OPEC has increased production in a very limited amount, and OPEC's supply has not yet increased significantly, so oil prices should not be overly bearish in the short term. Maintain a range strategy of buying low and selling high for oil prices, but currently, oil prices need to test OPEC's willingness to support prices through exports. It is recommended to wait and see in the short term and wait for a decline in OPEC exports to confirm when oil prices fall [2]. - After the bullish factors are realized, the methanol market has entered a short - term consolidation. The port inventory has further decreased due to port back - flow and trans - shipment. However, the import arrivals will remain high, and the port olefin plants have maintenance plans. The overall supply is at a high level, and the methanol fundamentals still face some pressure. It is expected to consolidate at a low level, and a unilateral strategy of waiting and seeing is recommended [4]. - The urea market has continued to rise in a volatile manner. The reserve demand and the increase in compound fertilizer production have led to an improvement in short - term demand. The supply is expected to decline seasonally. The overall supply - demand situation of urea has improved, and there is support from export policies and costs. It is expected to build a bottom in a volatile manner. It is recommended to consider buying on dips [7]. - For rubber, a neutral approach is currently adopted, and short - term operations with quick entry and exit are recommended. Holding a hedging position of buying RU2601 and selling RU2609 is advised [12]. - The PVC market has a poor fundamental situation. The domestic supply is strong while the demand is weak, and it is difficult to reverse the oversupply situation. Although there is a short - term rebound driven by sentiment, in the medium term, a strategy of shorting on rallies is recommended before there is a substantial reduction in industry production [14]. - For pure benzene and styrene, the non - integrated profit of styrene is neutral to low, and there is a large space for valuation repair. The supply of pure benzene is still abundant, and the port inventory of styrene has been continuously decreasing. It is recommended to go long on the non - integrated profit of styrene before the first quarter of next year [17]. - For polyethylene, although the PE valuation has limited downward space, the high number of warehouse receipts in the same period of history suppresses the market. The overall inventory is at a high level but is decreasing. It is recommended to go long on the LL5 - 9 spread on dips [20]. - For polypropylene, under the background of weak supply and demand, the overall inventory pressure is high. There is no prominent contradiction in the short term. It is expected that the supply - surplus situation at the cost end will change in the first quarter of next year, which may support the market [23]. - For PX, it is expected to have a slight inventory build - up in December. The current valuation is at a neutral level, and opportunities to go long on dips are worth paying attention to [26]. - For PTA, the supply will maintain a high level of maintenance in the short term, and the demand will gradually decline due to the off - season. The PTA processing fee has limited upward space in the short term. Opportunities to go long on dips based on expectations are recommended [28]. - For ethylene glycol, the domestic supply has improved due to unexpected maintenance, but the overall load is still high, and the port inventory is in a build - up cycle. There is a risk of a rebound due to further increases in maintenance. [31] Summary by Relevant Catalogs Crude Oil - **Market Information**: INE's main crude oil futures closed down 1.70 yuan/barrel, a 0.40% decline, at 426.60 yuan/barrel.

The overall supply - demand situation of urea has improved, and there is support from export policies and costs. It is expected to build a bottom in a volatile manner. It is recommended to consider buying on dips [7]. Rubber - **Market Information**: The rubber price has been consolidating. The exchange's RU inventory warrants are at a low level, and the buying demand for winter storage is a bullish factor. The bulls believe in seasonal expectations and improved demand, while the bears are concerned about macro uncertainties and weak demand. As of December 18, 2025, the operating rate of all - steel tires in Shandong tire enterprises was 64.66%, up 1.08 percentage points from last week and 2.56 percentage points from the same period last year.
