1. Report Industry Investment Rating - All the commodities in the report are rated as "Oscillating" [1][2][4][5][7] 2. Core Viewpoints of the Report - The oil market is currently affected by the uncertainty of supply - side expectations, and oil prices are expected to oscillate. The fuel oil market is also in an oscillating state due to factors such as supply and demand and sanctions. The asphalt market has increased production expectations in September, and the price will oscillate while paying attention to the actual demand. The polyester market has improved demand expectations, and the supply has shrunk due to some device overhauls, with prices following cost fluctuations. The rubber market has support from demand, and the price will oscillate in the short - term. The methanol market will maintain an oscillating trend considering supply and demand changes. The polyolefin market is gradually transitioning to a state of both strong supply and demand, with narrow - range oscillations. The PVC market is expected to oscillate weakly due to factors such as supply, demand, and inventory [1][2][4][5][7] 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Wednesday, WTI October contract rose $0.9 to $64.15/barrel (1.42% increase), Brent October contract rose $0.83 to $68.05/barrel (1.23% increase), and SC2510 closed at 481.5 yuan/barrel, down 4.9 yuan/barrel (1.01% decrease). Last week, US crude, gasoline, and distillate inventories decreased due to increased demand. Russia extended the gasoline export ban until September 30. Ukraine's drone attacks on Russian oil export pipelines and US tariffs on Indian imports affected Russian crude exports, with weekly shipments decreasing to 272 barrels/day in the week ending August 24. The market is affected by supply - side uncertainty, and oil prices are expected to oscillate [1] - **Fuel Oil**: On Wednesday, FU2510 fell 2.39% to 2821 yuan/ton, and LU2511 fell 1.47% to 3485 yuan/ton. Affected by US sanctions on Iran and previous low valuations, FU had a strong rise this week but回调ed with the oil price yesterday. The Chinese refinery's average utilization rate of atmospheric and vacuum distillation units was 63.61% as of August 27, up 1.04 percentage points from last week. The Asian low - sulfur fuel oil market structure weakened further, and the high - sulfur fuel oil supply pressure is expected to continue. FU is affected by sentiment and is expected to oscillate [2] - **Asphalt**: On Wednesday, BU2510 fell 0.57% to 3505 yuan/ton. The domestic refinery's asphalt production plan in September is about 2.64 million tons, a 10% increase from August and a 33% increase from the same period last year. This week, the domestic refinery's asphalt inventory level was 27.15%, down 0.66% week - on - week, and the social inventory rate was 33.94%, up 0.04% week - on - week. The asphalt plant's device utilization rate was 36.67%, down 0.25% week - on - week. In September, the demand is expected to increase, and the price will oscillate while paying attention to the actual demand [2][4] - **Polyester**: TA601 closed at 4824 yuan/ton, down 0.94%; EG2601 closed at 4481 yuan/ton, down 0.2%. The polyester yarn sales in the Yangtze River Delta region are still weak, with an average sales estimate of about 30%. A 300,000 - ton/year synthetic gas - to - ethylene glycol device in Shanxi is restarting, and a cracking device in Singapore has an unexpected delay in restart. The demand improvement brings positive support, and the supply has shrunk due to device overhauls. The prices of PX and TA follow cost fluctuations, and the ethylene glycol price is favorable due to reduced imports and lower inventory [4][5] - **Rubber**: On Wednesday, RU2601 fell 125 yuan/ton to 15760 yuan/ton, NR fell 175 yuan/ton to 12615 yuan/ton, and BR fell 135 yuan/ton to 11710 yuan/ton. From January to July, Vietnam's total exports of natural rubber and mixed rubber decreased by 0.8% year - on - year, but exports to China increased by 5% year - on - year. The supply - side prices of cup rubber and latex are relatively firm, and the demand - side tire exports have increased, supporting the short - term price to oscillate [5] - **Methanol**: The spot price in Taicang is 2250 yuan/ton. Recently, there have been many domestic device overhauls, and the supply is at a phased low. Overseas, Iranian device loads are high, and short - term arrivals will remain high. However, with the increase in the price difference between Europe, India, and China, the arrival volume will decrease in the long - term. The MTO device load in East China is not high, and the port inventory will increase in the short - term. The price is expected to oscillate [5][7] - **Polyolefins**: The mainstream price of East China wire - drawing PP is 6910 - 7080 yuan/ton. The production profit of different raw material - based PP varies. The subsequent production volume will remain high, and the downstream enterprise's operating rate is currently low but is expected to increase with the approaching of the peak demand season. The market is gradually transitioning to a state of both strong supply and demand, and the price will oscillate narrowly [7] - **Polyvinyl Chloride (PVC)**: The market price in East China, North China, and South China has adjusted weakly. The domestic real - estate construction has stabilized and recovered, and the demand for pipes and profiles is expected to increase. However, exports will be affected by India's anti - dumping policy. The supply remains high, and the price is expected to oscillate weakly [7][8] 3.2 Daily Data Monitoring - This part provides the basis and reference for analyzing the market trends of various energy - chemical products by presenting the spot prices, futures prices, basis, basis rates, and their changes of multiple energy - chemical varieties on August 27 and 26, as well as the position of the latest basis rate in historical data [9] 3.3 Market News - The US imported about 74,000 barrels per day of Venezuelan crude oil in the week ending August 22, which is the first time since the US government issued a new license to Chevron to operate in Venezuela.

Core Views Chlor - Alkali Industry - The caustic soda spot is expected to continue rising steadily, but the futures may face short - term resistance. PVC has large supply - demand pressure, and short - selling opportunities at high prices can be considered [2]. Polyester Industry Chain - PX is expected to have short - term low - buying opportunities, and the PX - SC spread can be expanded. PTA should be observed in the short term, with low - buying opportunities and TA1 - 5 reverse spreads. Ethylene glycol is expected to fluctuate strongly in the short term. Short - fiber and bottle - chip strategies are similar to PTA [6]. Pure Benzene - Styrene Industry - Pure benzene trends are expected to be weakly volatile, and BZ2603 should follow oil prices and styrene fluctuations.
