1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The oil price is expected to continue oscillating. The uncertainty in the crude oil market lies in the supply - side structural contradictions caused by sanctions, but during the current off - season of demand, the overall conflict is not obvious, and the impact on prices is relatively mild [1]. - The absolute prices of fuel oil (FU and LU), asphalt (BU), polyester, rubber, methanol, polyolefins, and polyvinyl chloride are all expected to oscillate, with attention paid to the fluctuations of oil prices under the influence of macro - factors [3][5][6]. 3. Summary According to Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Thursday, the WTI December contract rose 0.09 dollars to 60.57 dollars/barrel (0.15% increase), the Brent December contract rose 0.08 dollars to 65.00 dollars/barrel (0.12% increase), and the SC2512 closed at 461.4 yuan/barrel, down 1.1 yuan/barrel (0.28% decrease). The meeting between Chinese and US leaders and trade achievements have positive impacts, but sanctions on Russian producers and potential OPEC+ production increase add uncertainties [1]. - **Fuel Oil**: On Thursday, the main contract of high - sulfur fuel oil (FU2601) fell 1.43% to 2751 yuan/ton, and the main contract of low - sulfur fuel oil (LU2601) rose 0.62% to 3255 yuan/ton. The Asian low - sulfur market structure has weakened due to weak downstream demand and sufficient supply, while the high - sulfur market is expected to remain stable [3]. - **Asphalt**: On Thursday, the main contract of asphalt (BU2601) fell 0.4% to 3254 yuan/ton. The supply pressure will ease in early November, and there are still construction rush expectations in some markets [3]. - **Polyester**: TA601 closed at 4570 yuan/ton, down 1.42%; EG2601 closed at 4032 yuan/ton, down 1.66%.

1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints of the Report - The prices of most energy and chemical products are expected to be volatile. Specifically, the price of crude oil is expected to return to a volatile state due to OPEC+'s production increase plan and concerns about weak demand; the prices of fuel oil, asphalt, polyester, rubber, methanol, polyolefin, and polyvinyl chloride are also expected to be volatile due to various factors such as supply and demand and cost [1][2][3][4][5] 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Monday, oil prices fluctuated weakly. The WTI December contract closed down $0.19 to $61.31 per barrel, a decline of 0.31%. The Brent December contract closed down $0.32 to $65.62 per barrel, a decline of 0.49%. The SC2512 closed at 464.9 yuan per barrel, down 3.5 yuan per barrel, a decline of 0.75%. OPEC+ tends to moderately increase production in December. Eight member countries have increased their production targets by a total of 2.7 million barrels per day through a series of monthly production increases, accounting for about 2.5% of global supply. The market's concern about weak demand continues to suppress oil prices, and it is expected that oil prices will return to a volatile state in the short term [1] - **Fuel Oil**: On Monday, the main fuel oil contract FU2601 on the Shanghai Futures Exchange closed up 1.28% at 2,842 yuan per ton; the main low-sulfur fuel oil contract LU2512 closed up 1.8% at 3,275 yuan per ton. Due to weak downstream demand and sufficient recent supply, the Asian low-sulfur market structure has weakened. The Asian high-sulfur market is expected to remain stable. In the short term, the absolute prices of FU and LU will rebound following the cost side, and attention should be paid to the fluctuations of oil prices under the influence of macro factors [2] - **Asphalt**: On Monday, the main asphalt contract BU2601 on the Shanghai Futures Exchange closed down 0.03% at 3,295 yuan per ton. From the perspective of refinery production schedules in early November, the supply pressure will be alleviated. In the short term, the absolute price of BU will rebound following the cost side, and attention should be paid to the fluctuations of oil prices under the influence of macro factors [2] - **Polyester**: TA601 closed at 4,616 yuan per ton yesterday, up 2.17%; EG2601 closed at 4,109 yuan per ton yesterday, up 0.78%. The production and sales of polyester yarn in Zhejiang and Jiangsu are generally good, with an average production and sales estimate of about 70%. The fundamentals of TA and EG have improved. In the short term, the prices of polyester products are expected to be volatile [2][3] - **Rubber**: On Monday, the main Shanghai rubber contract RU2601 rose 45 yuan per ton to 15,380 yuan per ton, and the main NR contract rose 35 yuan per ton to 12,540 yuan per ton.

Macroscopically, the Sino-US economic and trade negotiations have reached a preliminary consensus, and it is expected that rubber prices will be strongly volatile [3] - **Methanol**: On Monday, the spot price in Taicang was 2,230 yuan per ton. In the short term, the port supply is still relatively high, and the short-term rebound of crude oil has a positive impact on the valuation of chemicals. Therefore, the performance of methanol may tend to be volatile [4] - **Polyolefin**: On Monday, the mainstream price of East China拉丝 was 6,560 - 6,650 yuan per ton. In the short term, the production will remain high, and the marginal increase in demand will gradually decline. The short-term rebound of crude oil supports the valuation, but the fundamental driving force is weakening. It is expected that polyolefin prices will enter a volatile stage [4] - **Polyvinyl Chloride**: On Monday, the price of the PVC market in East China fluctuated slightly. The supply remains at a high level, the domestic demand has slowed down, and the export is expected to be weak. The price has a demand for phased repair, but the rebound height is limited under the suppression of high inventory [5] 3.2 Daily Data Monitoring - The report provides the basis data of various energy and chemical products on October 28, 2025, including spot prices, futures prices, basis, basis rates, and their changes and historical quantiles [6] 3.3 Market News - Market participants said that OPEC+ tends to moderately increase production in December to regain market share.

Geopolitical factors, such as Trump's remarks on Russia and US - India trade progress, may drive up short - term price volatility [1]. - **Fuel Oil**: On Wednesday, the main fuel oil contracts FU2601 and LU2512 rose. In September 2025, China's bonded marine fuel oil imports increased month - on - month but decreased year - on - year, while exports increased both month - on - month and year - on - year. The Asian low - sulfur and high - sulfur fuel oil markets are under pressure due to weak demand and sufficient supply [2]. - **Asphalt**: On Wednesday, the main asphalt contract BU2601 rose. This week, the social inventory rate decreased slightly, the refinery inventory increased slightly, and the plant operating rate increased slightly. Terminal demand is weak, and high supply may suppress prices [2]. - **Polyester**: TA601, EG2601, and PX futures rose on Wednesday. Some MEG and refinery units have maintenance plans. Korean PX exports increased. Polyester supply is sufficient, and downstream demand provides some support. The polyester chain follows cost fluctuations [4]. - **Rubber**: On Wednesday, the main rubber contracts showed little change. The EU's policy implementation for small and medium - sized enterprises is postponed. Some rubber varieties have tight liquidity, and the price is expected to oscillate weakly in the short - term [4][6]. - **Methanol**: On Wednesday, methanol prices were reported. Domestic and overseas supply has returned to a high level, but future Iranian production growth is limited. Port sanctions may reduce future arrivals. It is recommended to consider long - methanol and short - polyolefin strategies and inter - month positive spread strategies [6]. - **Polyolefins**: On Wednesday, polyolefin prices and production margins were reported. Short - term supply will remain high, and demand growth will slow down. Crude oil rebound supports prices, but the fundamentals drive is weakening, and prices are expected to oscillate [6][7]. - **Polyvinyl Chloride (PVC)**: On Wednesday, PVC prices in different regions changed little. Supply - demand pressure is high, and exports are affected by policies. The price has a need for phased repair, but the rebound is limited by high inventories [7].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Crude oil prices are expected to continue weak and volatile. The IEA predicts a large supply surplus in the world oil market next year, with supply growth significantly outpacing demand growth, putting strong pressure on oil prices. Currently, the market faces pressure from both supply and demand sides, and the peak demand season is fading with no highlights in the downstream [1]. - Fuel oil prices are expected to be volatile and weak in the short - term. The supply of low - sulfur fuel oil in Singapore is sufficient, while the high - sulfur fuel oil market is relatively strong, but Trump's new round of tariff hikes is pressuring oil prices [2]. - Asphalt prices are expected to be volatile and weak in the short - term, with a smaller decline than crude oil and fuel oil. There is still some construction rush expectation after the festival, but the significant increase in previous production may suppress prices [2]. - Polyester chain prices are expected to be volatile and weak, following the movement of crude oil prices. The supply of TA and EG is in a loose pattern, and the weak sales of polyester products are observed. Pay attention to potential sudden plant overhauls under low processing fees [2]. - Rubber prices are expected to be volatile and weak. The end of the typhoon season leads to normal rubber tapping in major production areas, while the high inventory of tire finished products and tariff - disturbed demand result in a situation of increasing supply and weakening demand [4]. - Methanol prices are expected to be volatile. The domestic supply has recovered, and the Iranian Busher plant has resumed production, but future production growth is limited due to winter gas restrictions. Consider long - methanol and short - polyolefin strategies and inter - month positive spread strategies [4]. - Polyolefin prices are expected to be weak. The short - term production will remain at a high level, and although there is still support from downstream orders in October, the marginal increase will gradually decline [6]. - PVC prices are expected to be volatile and weak. The supply remains at a high level, domestic demand is slowing down, and exports are expected to be weak due to anti - dumping policies and trade frictions. The total inventory pressure is large [6]. 3.

1. Report Industry Investment Rating The report does not provide an overall industry investment rating. However, for each specific energy and chemical product, the following ratings are given: - Crude oil: Oscillating [1] - Fuel oil: Oscillating [3] - Asphalt: Oscillating [3] - Polyester: Oscillating [5] - Rubber: Oscillating [7] - Methanol: Oscillating [8] - Polyolefins: Oscillating weakly [8] - Polyvinyl chloride (PVC): Oscillating [9] 2. Core Viewpoints of the Report - **Crude oil**: Geopolitical tensions have eased with the Israel - Hamas cease - fire agreement, leading to a decline in the geopolitical premium of crude oil and downward pressure on oil prices. US refinery operations and inventory data show an increase in commercial crude oil inventories and a decrease in gasoline and distillate inventories. Under the triple tests of supply increase expectations, geopolitical factor easing, and demand entering the off - season, oil prices are expected to continue their weakening trend [1]. - **Fuel oil**: Although the East - West arbitrage window for low - sulfur fuel oil is mostly closed, the inflow of component oils for blending low - sulfur fuel oil continues to increase. The Asian high - sulfur fuel oil market is relatively stable, but the supply may increase in the future. The high - sulfur fundamentals may be slightly stronger than the low - sulfur [3]. - **Asphalt**: During the National Day holiday, the overall supply of asphalt increased slightly. The continuous rainfall in the southern regions hinders downstream construction, while the northern regions still have some catch - up demand. The recent significant increase in asphalt production may put pressure on prices after the peak season [3]. - **Polyester**: In the fourth quarter, there will be some overseas PX device overhauls, and the ethylene glycol production capacity may continue to increase. The demand for winter fabrics has recovered seasonally but is expected to weaken in the second half of October. Under the situation of supply increase and demand weakening, the fundamentals of TA and ethylene glycol are weak, and their prices are expected to oscillate weakly [5]. - **Rubber**: Affected by Typhoon "Maideme", the rubber production in Hainan Island is expected to decrease. The US tariff on heavy - truck imports may suppress global rubber demand. After the holiday, rubber prices are expected to oscillate, and attention should be paid to new rubber warehouse receipts and crude oil price fluctuations [7]. - **Methanol**: The market is concerned about Iran's winter gas - rationing news. With the recovery of MTO device operations in East China, port demand has significantly increased, but MTO profit compression may affect refinery maintenance plans. In the short term, methanol prices are suppressed by high inventories and tend to oscillate [8]. - **Polyolefins**: Poor profit performance may lead to a high level of maintenance, and domestic production is unlikely to increase significantly in the short term. After the holiday, downstream orders will gradually decline, affecting the procurement of raw materials. Supply pressure remains high, demand has peaked and declined, and polyolefin prices are expected to oscillate weakly [8]. - **PVC**: In the fourth quarter, high - supply status will continue. As the peak season in October ends, downstream operations are expected to decline, and exports may weaken due to India's anti - dumping duties. High inventory pressure will restrict price increases, and market fluctuations may increase [9]. 3.
