Report Industry Investment Rating - The report does not explicitly provide an overall industry investment rating. However, for individual commodities, the ratings are as follows: - Crude oil: Oscillating [1] - Fuel oil: Oscillating [3] - Asphalt: Oscillating [3] - Polyester: Oscillating [3] - Rubber: Oscillating [5] - Methanol: Oscillating, with a bias towards strength [5] - Polyolefins: Oscillating [6] - Polyvinyl chloride (PVC): Oscillating, with a bias towards weakness [6] Report's Core View - The report analyzes the market conditions of various energy and chemical commodities on September 2, 2025. It takes into account factors such as geopolitical situations, supply - demand dynamics, and cost - end fluctuations to provide views on price trends for each commodity. For example, due to geopolitical tensions in the Red Sea and the Russia - Ukraine situation, the oil market's geopolitical pricing may rise again, and oil prices can be considered from a rebound perspective [1]. Summary by Relevant Catalogs Research Views - **Crude oil**: On Monday, Brent's new November contract rose 0.67 dollars to 68.15 dollars per barrel, a 0.99% increase. SC2510 closed at 488.9 yuan per barrel, up 5.3 yuan or 1.10%. Geopolitical factors such as the possible suspension of diplomatic efforts and the Red Sea missile incident may lead to a rebound in oil prices [1]. - **Fuel oil**: The main contract of high - sulfur fuel oil (FU2510) rose 0.25% to 2832 yuan per ton, while the main contract of low - sulfur fuel oil (LU2511) fell 0.49% to 3474 yuan per ton. The expected reduction in Western arbitrage cargo inflows in September may boost the fundamentals of low - sulfur fuel oil, but overall demand for both high - and low - sulfur fuel oil lacks significant highlights [3]. - **Asphalt**: The main contract of asphalt (BU2510) rose 1% to 3540 yuan per ton. In September, the demand for road construction in the north increases, but the rise in supply in North China and Northeast China may limit price increases. Overall, the supply - demand contradiction is expected to ease, and prices may rise further [3]. - **Polyester**: TA601 closed at 4772 yuan per ton, down 0.25%. EG2601 closed at 4427 yuan per ton, down 0.87%. PX supply is high, and downstream TA maintenance volume is increasing. TA prices are expected to be supported and oscillate. Ethylene glycol prices are expected to oscillate with a bias towards strength due to supply reduction and demand increase [3][4]. - **Rubber**: The main contract of natural rubber (RU2601) remained unchanged at 15860 yuan per ton, while the main contract of 20 - number rubber (NR) fell 15 yuan to 12680 yuan per ton. Supply weather is favorable, raw material prices fluctuate slightly, demand is stable domestically and weak overseas, and inventory is slightly decreasing. Rubber prices are expected to oscillate [5]. - **Methanol**: Due to the recovery of profits, MTO devices may resume production. In September, supply growth is limited, demand is expected to pick up, and inventory is expected to peak. Methanol prices are expected to enter a phased bottom area [5]. - **Polyolefins**: In September, supply and demand are both strong, inventory is gradually transferred from society to downstream, and fundamentals have few contradictions. Polyolefin prices are expected to continue to fluctuate narrowly [6]. - **Polyvinyl chloride (PVC)**: Real - estate construction recovery is weak, and demand for PVC downstream products is limited. With India's higher anti - dumping duties, exports are expected to decline. PVC prices in September are expected to oscillate with a bias towards weakness [6]. Daily Data Monitoring - The report provides data on the basis of various energy and chemical products, including spot prices, futures prices, basis, basis rates, and their changes and historical quantiles [7]. Market News - Trump is considering suspending diplomatic efforts until more flexibility is shown. Europe is trying to persuade Zelensky to wait for better conditions, which may disrupt the progress made since the Russia - US summit. The EU is formulating a plan to deploy multinational forces to Ukraine [10]. - Despite US pressure, Russia remains India's largest crude oil supplier, accounting for 31.4% of India's crude oil imports in July [10].

Report Summary 1. Industry Investment Rating - Not provided in the document. 2. Core Viewpoints - In September, after entering the traditional peak season, the resumption of production in the north and south and the increase in crystalline silicon will become marginal drivers. There is room for improvement in the supply - demand pattern of industrial silicon, and the overall operating center is expected to rise slightly. [4] - After the previous anti - involution news was fully priced, the trading center of polysilicon gradually shifted to the fundamental logic. Due to the limitation of the terminal power station yield, the acceptance of price increases in the component link has reached its peak, and the silicon material has cooled down along with the downstream market sentiment. Before specific policy measures are introduced, the market is still in a game between policy boost and fundamental drag. Polysilicon has entered a range mode with obvious top and bottom, and policy dynamics have a phased disturbance effect on the market. [4] 3. Summary by Directory 3.1 Futures Prices - In August, the industrial silicon futures fluctuated weakly. As of the 29th, the main contract closed at 8,420 yuan/ton, with a monthly decline of 4.97%.

Report Industry Investment Rating - No relevant content provided Core Viewpoints of the Report - After continuous decline in August, the current yield of the ten - year treasury bond once approached 1.85%, more than 45BP higher than the reverse repurchase policy rate. With long - term capital and economic fundamentals both favorable to the bond market, the allocation power of the bond market is gradually increasing, and the bond market adjustment is basically in place. However, the expectation of anti - involution promotes the continuous strengthening of the equity market, which is negative for long - term bonds.

Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints - In September, the resumption of alumina production will increase, and warehouse receipts will gradually accumulate, further strengthening the expectation of oversupply. Due to the rainy season in Guinea and the domestic parade period, there are strong disturbance factors on the ore side. Alumina should be mainly shorted on rallies, but chasing the decline is not recommended. - Before the "Golden September" peak season, the stocking speed of downstream sectors has started quickly. There is a possibility of exceeding expectations in the demand for electrolytic aluminum during the peak - season cycle, and the profits of the aluminum industry will continue to shift from the upstream to the downstream. Driven by the Fed's interest - rate cut in September and the domestic peak season, electrolytic aluminum has strong upward momentum. - Due to the peak - season mismatch of aluminum alloy, there is room for the spread of far - month contracts to continue to repair. Opportunities such as the widening of the AL2510 - AO2510 spread and the narrowing of the AL2511 - AD2511 spread can be tracked. Attention should be paid to the pace of the US interest - rate cut and the confirmation or falsification of strong demand. [3] 3.

Report Industry Investment Rating - Not provided in the content Core Viewpoints - In September, the PVC fundamentals still face pressure, with high inventory levels, and the price is expected to fluctuate weakly. However, it is necessary to be vigilant about a new round of speculative expectations brought by unexpected policies [2] Summary by Directory Supply:检修计划增加有限，预计产量维持高位 - In early August, many production enterprises resumed operations after maintenance, leading to a decrease in loss volume compared to July. It is expected that maintenance in September will be high at the beginning and low at the end, and the production volume will remain at a high level with fluctuations [2][5] - The operating rate increased slightly month - on - month. The 8 - month production volume increased by 60,000 tons, all from ethylene - based plants, and it is expected to remain at a high level with fluctuations subsequently [19] Demand:房地产施工将逐步回升，预计管材和型材开工增加 - In August, the downstream operating rate recovered but decreased significantly year - on - year. It is expected to remain stable in September. The real estate transactions are fluctuating at a low level. Although the real estate construction will recover, it is still weak overall, providing limited support for the demand of PVC downstream pipes and profiles. With India imposing higher anti - dumping duties on Chinese PVC, exports are expected to decline [2][21][34] - In August, downstream enterprises made small - scale stockpiling, and as the September delivery approached, traders were actively trading [28] Inventory:供需压力仍在，总库存高位震荡 - The fundamentals still show strong supply and weak demand. As the basis weakened significantly, refinery inventories flowed into the social market, leading to an increase in total inventory. The warehouse receipts also increased rapidly. In September, domestic demand is expected to recover, but exports are expected to decline, and the fundamental pressure remains high. It is expected that the inventory will remain at a high level with limited changes [2][44] Spread:预计基差逐步走强 - The fundamentals still show strong supply and weak demand. As the delivery approaches, the near - month contract has a relatively large decline [54] Profit:电石法和乙烯法利润表现偏弱 - The profit performance of the calcium carbide method and the ethylene method is weak [58]
