1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In the short - term, PX and PTA have limited supply pressure, polyester demand remains stable, and the futures market has support at the bottom. However, the continuous weakening of the terminal restricts the rebound momentum, and the market is in a range - bound pattern. The price of ethylene glycol is expected to fluctuate at a low level due to insufficient demand. In the medium - to - long - term, the demand drive is insufficient, and supply changes dominate the market rhythm. The polyester sector shows a differentiated trend in the fourth quarter, with PX and PTA being relatively strong and ethylene glycol having limited upward potential [33]. - For methanol, in the short - term, although the shutdown of Iranian plants and tight supply in the inland region boost the market, the high - supply and high - operation situation will continue, and the demand support is insufficient, so the upward space of the futures market is limited. In the medium - to - long - term, the import is expected to decrease from mid - December to next year, but the demand increase is still weak, and the market may fluctuate widely. - For plastics, in the short - term, the social inventory continues to decline, but the supply remains high, and the demand support is weak. The market may continue to fluctuate in a low - level range. In the medium - to - long - term, the supply pressure may not decrease, and the overall demand is expected to weaken significantly, so the plastic market may continue to be weak [61]. 3. Summary by Relevant Catalogs 3.1 Macro and Crude Oil Important News - Geopolitical news: Ukrainian President Zelensky plans to continue implementing the Geneva Conference results with the US. Russian President Putin said that the US delegation will visit Moscow next week, but Russia will not make concessions on key issues, and negotiating with the current Ukrainian leadership is meaningless at this stage. OPEC+ is expected to maintain the current crude oil production policy and may establish a new mechanism to assess member countries' production capacity [5]. - Crude oil supply and demand: Russian seaborne crude oil imports decreased by 23% in the week ending November 25. US sanctions on Russian oil companies have led to a reduction in purchases by major buyers. US commercial crude oil, gasoline, and distillate inventories all increased in the week ending November 21 [6][7]. - Market sentiment: Fed officials' dovish speeches have increased the market's expectation of a December interest rate cut, with the probability of a 25 - basis - point cut rising to 86.9%. The US dollar index is under pressure, and the 10 - year US Treasury yield has declined rapidly [6]. 3.2 Polyester Sector Futures and Spot Prices - Futures prices: WTI crude oil increased by 0.65% week - on - week, PX601 decreased by 1.64%, TA601 decreased by 1.36%, EG601 increased by 1.33%, PF602 decreased by 0.93%, and PR601 decreased by 0.70%. - Spot prices: Naphtha decreased by 1.24%, PX CFR Taiwan decreased by 0.96%, PTA spot decreased by 0.39%, ethylene glycol in East China increased by 0.34%, polyester staple fiber in East China decreased by 0.40%, and polyester bottle chips in East China decreased by 0.35% [9]. 3.3 Supply and Demand of Polyester Raw Materials - PX: The 800,000 - tonne unit of Sinochem Quanzhou has been shut down for maintenance, but the restart of Shanghai Petrochemical has increased supply. As of November 28, the domestic PX weekly average capacity utilization rate was 89.74%, and the output was 752,600 tonnes. Asian PX capacity utilization decreased slightly to 79.4%. Next week, supply is expected to decline slightly, and PX processing fees have bottom - end support [14]. - PTA: The restart of Shenghong's unit was offset by the maintenance of Yisheng Ningbo and Sichuan Energy Investment units, resulting in a slight decrease in supply this week. As of November 28, the domestic PTA weekly capacity utilization rate was 71.92%, and the output was 1.3747 million tonnes. Social inventory continued to decline. Next week, supply is expected to increase slightly [17]. - Ethylene glycol: The shutdown of Sinochem Quanzhou's unit and the delay of Puyang's restart led to a slight decrease in supply this week. As of November 28, the domestic ethylene glycol weekly average capacity utilization rate was 62.67%. The restart of Hongsifang's unit and the planned restart of Huayi's unit are expected to increase supply next week, but supply is expected to decline in December [19]. 3.4 Polyester End and Terminal Situation - Polyester end: The weekly average polyester operating rate was 87.38%, a decrease of 0.21 percentage points week - on - week. - Terminal: As of November 28, the operating rate of Jiangsu and Zhejiang looms was 66.93%, a decrease of 0.76 percentage points. The order days of Chinese weaving sample enterprises were 13.04 days, a decrease of 0.50 days, and the坯布 inventory days were 23.45 days, an increase of 0.60 days [20][30]. 3.5 Methanol and Polyethylene Data - Price trends: The futures price of MA2601 increased by 6.54%, and the spot price of methanol in Taicang increased by 3.71%.

This week, some units resumed production, and next week, Jiutai New Materials plans to resume production [42]. - Methanol demand: The overall downstream operating rate increased slightly, but MTO operating rate has limited room for further increase, and traditional downstream is in the off - season. The 1.2 - million - tonne acetic acid unit of Celanese has been shut down for maintenance since November 28 [45]. - Methanol inventory: As of November 26, the port inventory was 1.3635 million tonnes, a decrease of 7.83%, and the inland inventory was 373,700 tonnes, an increase of 4.19%. Iranian units have entered the gas - restricted shutdown state [48]. - Plastic supply: As of November 27, the domestic plastic operating rate was 84.51%, and the output was 684,800 tonnes. This week, some units were under maintenance, and some units resumed production. Next week, no units are planned for maintenance, and some units are expected to resume production [51]. - Plastic demand: As of November 27, the plastic downstream operating rate was 44.3%, a decrease of 0.39 percentage points. The demand for greenhouse films is expected to decline, and the packaging film is still digesting previous orders, with a decreasing scale [55]. - Plastic inventory: As of November 26, the social plastic inventory was 471,100 tonnes, a decrease of 3.05%, and the two - oil enterprise inventory was 384,000 tonnes, a decrease of 9.43%.

Report Summary 1. Report Industry Investment Rating - No investment rating information is provided in the report. 2. Core View of the Report - The L2601 contract of polyethylene fell 1.31% to close at 6,707 yuan/ton. Last week, the impact of Zhongtianhechuang's shutdown continued, and new maintenance units were added in Wanhua Chemical, Zhongying Petrochemical, and Jilin Petrochemical, leading to a decline in PE production and capacity utilization. The downstream operating rate increased slightly, with a slight decline in the agricultural film operating rate and a small increase in the packaging film operating rate. Factory and social inventories decreased month - on - month, and the inventory pressure was not significant. Oil - based and coal - based profits remained in a theoretical loss state. This week, the Shanghai Petrochemical and Maoming Petrochemical units are planned for maintenance, while the Zhongying Petrochemical, Zhongtianhechuang, and Zhenhai Refining & Chemical units are scheduled to restart, so PE production and capacity utilization are expected to increase month - on - month, with relatively high supply. The demand center of greenhouse films has shifted south, and southern orders support the high operating rate of agricultural film enterprises; the orders for packaging films have decreased, and the operating rate is expected to decline. In terms of cost, due to statements from US and Ukrainian officials indicating that Ukraine has in principle agreed to the peace agreement proposed by the US, international oil prices closed lower yesterday. In the short term, the situation of supply exceeding demand for LLDPE may continue, with limited cost - side support, and L2601 is expected to fluctuate weakly, with the daily K - line focusing on the support around 6,680 [2]. 3.
