1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints of the Report - The overall driving force of oil prices is limited, and they will continue to fluctuate. The prices of fuel oil, asphalt, polyester, rubber, methanol, polyolefin, and PVC are also expected to maintain a fluctuating trend [1][2][4][5][7][8]. 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Monday, oil prices moved higher. WTI January contract closed up $0.77 to $59.32 per barrel, a 1.32% increase; Brent February contract closed up $0.79 to $63.17 per barrel, a 1.27% increase; SC2601 closed at 453.6 yuan per barrel, up 0.2 yuan per barrel, a 0.04% increase. OPEC and 8 major non - OPEC oil - producing countries decided to maintain the production plan set in early November and suspend production increases in Q1 2026. The current global economic outlook is relatively stable, and the oil market fundamentals are sound. Overall, the driving force of oil prices is limited, and they will continue to fluctuate [1]. - **Fuel Oil**: On Monday, the main fuel oil contract FU2601 on the Shanghai Futures Exchange rose 0.36% to 2495 yuan per ton, and the low - sulfur fuel oil contract LU2602 rose 0.89% to 3053 yuan per ton. The closure of the East - West arbitrage window is expected to reduce the inflow of low - sulfur arbitrage cargoes to Singapore in December, but the inventory of blending raw materials for 0.5% sulfur marine fuel around Singapore is sufficient, and the inflow of low - sulfur fuel oil from Southeast Asia is increasing. The high - sulfur fuel oil market in December is also expected to face a situation of sufficient supply. The attitude towards oil prices in December is relatively pessimistic, and the absolute prices of FU and LU are expected to remain weak. Attention should be paid to the impact of the Russia - Ukraine situation and the overseas refined oil market on the relative strength of high - and low - sulfur markets [2]. - **Asphalt**: On Monday, the main asphalt contract BU2601 on the Shanghai Futures Exchange rose 0.44% to 2990 yuan per ton. In November, the supply and demand of asphalt were both weak. The total domestic asphalt supply was expected to be 2.53 million tons, a 15.2% month - on - month decrease, and the domestic downstream consumption was 2.74 million tons, a 13.8% month - on - month decrease. In December, the supply will further decrease, but the decline may be relatively limited. The demand in the northern region will drop to a low level, and the winter storage demand will gradually start. The current social inventory is slightly higher than the same period last year, with a certain inventory pressure. In the short term, the asphalt price is expected to fluctuate at a low level [2]. - **Polyester**: TA601 closed at 4762 yuan per ton on the previous day, up 1.32%; EG2601 closed at 3882 yuan per ton, down 0.08%. The inventory of the East China main port area for MEG on December 1 was about 753,000 tons, a 21,000 - ton increase from the previous period. The downstream demand at the end of the year is gradually weakening, but the polyester start - up still has resilience, and the high - level maintenance power is insufficient. The PX price is expected to be under pressure at the end of the year. The TA price is expected to fluctuate with the cost, and the ethylene glycol price is expected to adjust widely [4]. - **Rubber**: On Monday, the main Shanghai rubber contract RU2601 fell 160 yuan per ton to 15250 yuan per ton. Indonesia's total exports of natural rubber and mixed rubber in the first 10 months were 1.43 million tons, a 6% year - on - year increase, and exports to China were 336,000 tons, a 135% year - on - year increase. The total inventory of natural rubber in Qingdao increased by 12,600 tons from the previous period. The rubber market has weak supply and demand fundamentals, and the rubber price is expected to fluctuate. Attention should be paid to the resumption of tapping in southern Thailand and the registration of new RU warehouse receipts [5]. - **Methanol**: On Monday, the spot price in Taicang was 2118 yuan per ton. In December, the domestic production is expected to decline slightly, and the import volume will decline from a high level. The overall demand for olefins is expected to increase. The port inventory is expected to enter the destocking stage from mid - December this year to early January next year, driving the methanol price to rebound, but it is expected to have an upper limit, showing a short - term fluctuating and strengthening trend. Attention should be paid to the strategy of going long on methanol and short on polyolefins [5][7]. - **Polyolefin**: On Monday, the mainstream price of East China拉丝 was 6320 - 6500 yuan per ton. In December, the number of newly - added maintenance enterprises will decrease, and the supply will further increase. The downstream demand will gradually weaken, and the market is expected to maintain rigid procurement. In December, the supply is strong and the demand is weak, but the futures price is expected to bottom - fluctuate if the crude oil price remains relatively stable [7]. - **Polyvinyl Chloride (PVC)**: On Monday, the PVC market price in East China fluctuated and sorted out. In December, the enterprise maintenance is at a low ebb, and the production will continue to increase. The demand from the real - estate construction for PVC downstream pipes and profiles is limited, and the downstream start - up is expected to continue to decline. The PVC price may tend to bottom - fluctuate [7][8]. 3.2 Daily Data Monitoring - The report provides the daily data monitoring of various energy - chemical products, including spot prices, futures prices, basis, basis rates, price changes, and the quantile of the latest basis rate in historical data for multiple products such as crude oil, liquefied petroleum gas, asphalt, etc. [9] 3.3 Market News - OPEC and 8 major non - OPEC oil - producing countries decided to maintain the production plan set in early November and suspend production increases in Q1 2026 due to seasonal factors. The current global economic outlook is relatively stable, and the oil market fundamentals are sound [11]. - The remarks of US President Trump about closing Venezuela's airspace increased geopolitical uncertainties.

1. Report Industry Investment Rating No relevant content provided. 2. 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, short - term oil prices should not be overly bearish. A low - buy and high - sell range strategy is maintained, but it's advisable to wait and see for now to verify OPEC's export price - support intention when prices fall [3]. - For methanol, with the potential positive impact of Iranian plant shutdowns materializing, the market has stopped falling and stabilized. The short - term bottom is expected to have emerged. However, high supply will limit further upward movement, and the market is likely to shift to a sideways adjustment. It's recommended to wait and see on the single - side and focus on positive spread opportunities for inter - month spreads [4]. - For urea, the price is expected to gradually emerge from the bottom range. With supply remaining high and demand improving, the inventory is decreasing. It's suggested to consider buying at low prices [6][8]. - For rubber, a neutral stance is taken currently. It's recommended to wait and see or engage in short - term trading. Holding a hedging position of buying RU2601 and selling RU2609 is advised [10]. - For PVC, the domestic supply - demand situation is weak, but short - term valuation has dropped to a low level. A mid - term strategy of shorting on rallies is recommended before substantial industry production cuts [14]. - For pure benzene and styrene, the non - integrated profit of styrene is moderately low, with significant upward valuation repair potential. When the inventory reversal point occurs, one can go long on the non - integrated profit of styrene [17]. - For polyethylene, the OPEC + plan to pause production growth in Q1 2026 may lead to a bottoming of crude oil prices. The long - term strategy is to short the LL1 - 5 spread on rallies [20]. - For polypropylene, in a context of weak supply and demand with high inventory pressure, the market may be supported when the supply - surplus situation at the cost end changes in Q1 next year [22]. - For PX, it is expected to experience a slight inventory build - up in December. Attention should be paid to opportunities for going long on dips [25]. - For PTA, supply disruptions are expected to decrease as processing fees stabilize. There are opportunities for going long on dips based on expectations [26][27]. - For ethylene glycol, the supply - demand outlook is weak in the medium term. A strategy of shorting on rallies is recommended [28]. 3.
