1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. 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].

Report Industry Investment Ratings - PX: ★☆☆ (One star, indicating a bullish/bearish bias with a driving force for price increase/decrease, but limited operability on the trading floor) [1] - PTA: ☆☆☆ (White star, suggesting a relatively balanced short - term bullish/bearish trend and poor operability on the trading floor, advisable to wait and see) [1] - Ethylene glycol: ☆☆☆ [1] - Short - fiber: ☆☆☆ [1] - Bottle chips: ☆☆☆ [1] - Methanol: ★☆☆ [1] - Urea: ★☆☆ [1] - PVC: ☆☆☆ [1] - Caustic soda: ★★★ (Three stars, representing a clearer bullish/bearish trend and a relatively appropriate current investment opportunity) [1] - Soda ash: ★☆☆ [1] - Glass: ☆☆☆ [1] Core Viewpoints - The petrochemical products market is generally weak, with different products showing various supply - demand and price trends. Some products have supply - demand improvement expectations in the short - term, while others face long - term supply pressure [2][3][5][6][7] - For most products, it is necessary to pay attention to factors such as device status, oil price trends, policy changes, and seasonal demand [3][5][6][7] Summary by Product Category Pure Benzene - Petrochemical products are weak, the unified benzene futures price has declined, and Sinopec has lowered the listed price. Although the port inventory has been decreasing, domestic demand is weak, resulting in a weak supply - demand balance. The BZ - NAP spread has slightly weakened, and the basis has declined [2] - There are expectations of supply - demand improvement in the third quarter due to domestic maintenance and seasonal demand recovery, but imports still pose pressure on the market, and the supply - demand situation may be under pressure in the fourth quarter [2] Polyester - The PX price dropped during the day, causing the PTA price to weaken. Terminal weaving is improving, demand is rising, and with no new PX installations planned for this year, the supply - demand outlook is improving, which is expected to drive up the industry chain. However, the market has already factored in these expectations, and stronger drivers are needed for the PX price to continue rising [3] - Ethylene glycol is fluctuating around 4,500 yuan/ton. Domestic production has increased, and terminal demand has improved, leading to simultaneous growth in supply and demand. A significant decrease in arrivals has boosted the market in the short - term. Whether it can continue to rise in the medium - term depends on policies and the pace of peak - season demand recovery [3] - The short - fiber supply - demand is stable. The price dropped with the cost during the day, and the short - term margin and spot processing margin weakened, but the futures processing margin rebounded. With limited new production capacity this year, the expected increase in peak - season demand will boost the short - fiber industry. If demand improvement materializes in the medium - term, a long - position configuration is advisable [3] - The bottle - chip industry faces long - term over - capacity pressure. Recently, the raw material price has rebounded, causing the bottle - chip processing margin to further decline and the basis to weaken. Attention should be paid to the implementation of petrochemical industry policies [3] Coal Chemical Industry - The methanol futures price dropped significantly during the day, and the port inventory increased substantially within the cycle. Currently, the operating rate of coastal olefin plants is low, and the arrival of imported methanol remains high. Although some coastal supplies are flowing back to the inland, the affected areas and the total amount of back - flowing supplies are limited. With the end of autumn maintenance and the outflow of Xinjiang supplies, inland methanol supply is increasing, the marginal demand for external procurement by olefin plants is weakening, the average operating rate of traditional downstream industries is declining, and the inventory of production enterprises is increasing. The port is expected to continue to accumulate inventory rapidly, and the current situation remains weak. Attention should be paid to the macro - environment and the possibility of restarting coastal MTO plants [5] - The urea futures price is fluctuating at a low level, and the spot price has slightly decreased. The enthusiasm for port collection in the industry has increased, and the port inventory has increased within the cycle, but the market sentiment is cautious. Supply remains high, demand is weakening seasonally, and production enterprises are continuously accumulating inventory. As the subsequent state reserve purchase approaches, it is expected that the purchases will be scattered, and it is unlikely that a concentrated purchase will drive up the urea price. The supply - demand pressure has become a trend, and attention should be paid to changes in export - related news that may affect market sentiment [5] Chlor - Alkali Industry - The PVC price dropped during the day. Although PVC itself is operating at a loss, the caustic soda market is performing well, and the profit of chlor - alkali integration is acceptable, so the cost support is not obvious. Qingdao Gulf has plans for new production, and supply pressure remains. Downstream purchasing enthusiasm is low, domestic demand is weak, and external demand is in the off - season. Social inventory has been increasing since July. The low valuation and weak reality are in a tug - of - war, and the futures price may fluctuate within a range [6] - The caustic soda price has dropped from a high level. The rigid demand from the alumina industry provides strong support, and the recent operating rates of non - aluminum industries such as pulp, viscose staple fiber, and printing and dyeing have slightly increased, with restocking demand providing support, and the inventory has been continuously decreasing. After the continuous increase in the spot price, non - aluminum downstream industries have recently shown resistance to the price. The profit is good, and there is still supply pressure in the future. The current price is not very cost - effective, and the room for further price increase is limited [6] Soda Ash - Glass - The soda ash price is fluctuating weakly during the day. Anhui Hongsifang has resumed operation, and Wucai Alkali Industry has stopped for maintenance and is expected to resume on the 29th. The supply is fluctuating slightly at a high level. The inventory decreased on Monday, but the inventory at all levels of the industry chain is high, and the weak reality persists. The fundamentals of the photovoltaic industry have improved recently, the price has rebounded, and some blocked kilns have been reopened. The rigid demand for heavy soda ash has slightly increased. In the long - term, the soda ash supply will remain under high pressure, facing a supply - demand surplus situation. It is advisable to short at high - level rebounds, but caution is needed at low - valuation levels [7] - The glass price is fluctuating. The decline in the spot price has narrowed, and the price has increased slightly in some areas. Due to the military parade in September, the operation of deep - processing plants in the Shahe area has been affected, and glass factories continue to accumulate inventory. Recently, the production capacity has changed little, and the daily melting volume remains at a relatively high level of 159,600 tons. The processing orders have improved month - on - month but are still weak year - on - year. The current situation is weak, but at the current low - valuation level, attention should be paid to whether there will be restocking demand during the traditional peak seasons of "Golden September and Silver October". It is expected that the downward range of the futures price is limited, and a long - position strategy near the cost can be considered [7]

Core Views of the Report - The report analyzes multiple energy and chemical products, including crude oil, fuel oil, asphalt, polyester, rubber, methanol, polyolefins, and PVC, and provides short - term price trend views for each product, mostly indicating an oscillatory trend [1][2][4][6]. 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Tuesday, oil prices declined. WTI October contract closed down $1.55 to $63.25 per barrel, a 2.39% drop; Brent October contract closed down $1.58 to $67.22 per barrel, a 2.3% drop; SC2510 closed at 486.8 yuan per barrel, down 10.9 yuan or 2.19%. Due to the US tariff increase on Indian goods, Indian refineries are expected to reduce Russian oil purchases. In October, India's Russian oil imports will be 400,000 barrels per day lower than the Q1 average, a 22% decrease. API data showed a decline in US crude, gasoline, and distillate inventories last week. Domestic refined oil retail prices were lowered. The current oil price is oscillating [1]. - **Fuel Oil**: On Tuesday, the main fuel oil contracts on the SHFE declined. Affected by US sanctions on Iran and low valuations, FU rose strongly this week. The Asian low - sulfur fuel oil market structure weakened due to concerns about abundant arbitrage cargo supply and weak demand. High - sulfur fuel oil supply pressure will persist. Currently, FU is highly volatile and is expected to oscillate [2]. - **Asphalt**: In August, asphalt demand was lower than expected due to capital recovery and rainy weather. In September, demand is expected to increase in both northern and southern markets. Refineries with crude oil quotas have good profit margins, and production is expected to be stable. With a slight rebound in oil prices, the absolute price of BU has increased slightly. Attention should be paid to the actual demand fulfillment [2]. - **Polyester**: TA601 closed up 0.16% at 4870 yuan per ton; EG2601 closed down 0.42% at 4490 yuan per ton. PX futures rose 0.34%. The production and sales of polyester yarn in Jiangsu and Zhejiang are weak. A 2.5 - million - ton PTA plant is under maintenance. Demand improvement and supply contraction bring positive support, and PX and TA still have room for growth. High ethylene glycol operating load and low port inventory are favorable for its price [4]. - **Rubber**: On Tuesday, the main rubber contracts showed mixed trends. Thailand's natural rubber exports in July increased month - on - month but decreased year - on - year. The 13th typhoon affected production areas, and raw material prices were firm. Tire exports increased, providing demand support. The fundamentals are strong, and short - term rubber prices are expected to oscillate strongly. There are maintenance plans for butadiene rubber plants in September and October, and butadiene prices are expected to oscillate strongly [4][6]. - **Methanol**: Domestic plant maintenance has led to a short - term low in supply, which will gradually recover. Iranian plants have high operating loads, and short - term arrivals will remain high but may decrease in the long term. The MTO plant load in East China is not high, and port inventories will increase. Methanol prices are expected to oscillate [6]. - **Polyolefins**: The production profit margins of various polyolefin production methods vary. Supply will remain high, and downstream demand is currently low but is expected to improve with the approaching peak season. Overall, polyolefins are moving towards a situation of strong supply and demand, and prices will oscillate narrowly [6][7]. - **PVC**: The PVC market prices in different regions showed different trends on Tuesday. Domestic real estate construction is stabilizing, and demand for pipes and profiles is expected to increase. Supply remains high, exports will weaken due to Indian anti - dumping policies. PVC prices are expected to oscillate weakly [7]. 3.2 Daily Data Monitoring - The report provides the basis data of multiple energy and chemical products on August 27, 2025, including spot prices, futures prices, basis, basis rates, and their changes and historical quantiles [8]. 3.3 Market News - The US plans to double the tariff on Indian goods to 50% from Wednesday, which is expected to reduce India's recent purchases of Russian oil.

1. Report Industry Investment Ratings - No investment ratings are provided in the reports. 2. Core Views of the Reports Polyester Industry - PX: Supply is expected to increase as maintenance devices restart, but demand may weaken. However, with the approaching peak season, the demand may strengthen. Short - term PX11 can be overweighted in the chemical sector, and the PX - SC spread can be widened [2]. - PTA: Supply is affected by planned outages due to low processing fees, but demand may pick up. It can be overweighted in the chemical sector, and TA1 - 5 may show a positive spread repair in the short - term [2]. - Ethylene Glycol: Domestic supply increases, port inventory is low, and demand is expected to improve. Short - term put option EG2601 - P - 4350 sellers can hold [2]. - Short - fiber: Supply increases as maintenance devices restart, and demand may improve with the approaching peak season, but the sustainability of downstream restocking is weak. PF10 can be overweighted in the chemical sector [2]. - Bottle - chip: In the peak consumption season, production cuts lead to inventory reduction, but the cost increase suppresses processing fees. PR is similar to PTA, and the main contract processing fee is expected to fluctuate between 350 - 500 yuan/ton [2]. Polyolefin Industry - PP: The price center moves down, and the weighted profit is compressed. The supply and demand both increase, achieving de - stocking. The LPO1 spread can be held [7]. - PE: The price is stable with a downward trend. High - maintenance continues until September, and the upstream shows de - stocking while the mid - stream accumulates inventory [7]. Methanol Industry - The valuation is neutral. The inland supply is high, but low inventory supports the price. The demand may improve as some MTO devices are expected to restart. The 01 contract may see a balance improvement after mid - September [9]. Chlor - alkali Industry - Caustic Soda: The spot price is expected to continue to rise steadily, but the short - term futures may face resistance. It is recommended to take profit on previous long positions [34]. - PVC: The cost - driven effect weakens, and the supply is expected to increase while the demand is weak. It is advisable to short at high prices [34]. Crude Oil Industry - The short - term oil price is affected by macro risks, geopolitical factors, and supply uncertainties. It is recommended to wait and see on the long - short side, and look for opportunities to widen the option spread after the volatility increases [38]. Urea Industry - The supply expands while the demand is weak, dragging down the price. Attention should be paid to the start time and intensity of autumn fertilizer preparation and the change in urea procurement by compound fertilizer enterprises [40]. Pure Benzene - Styrene Industry - Pure Benzene: The supply is sufficient, and the fundamental improvement is marginal. BZ2603 should follow the fluctuations of oil price and styrene [43]. - Styrene: The demand is expected to improve, but the high supply and inventory pressure prices. EB10 can be shorted in the short - term [43]. 3.

Report Summary 1) Report Industry Investment Rating - No information provided on the industry investment rating. 2) Core Viewpoints - PTA: Domestic PTA device failures led to a slight decline in production. The spread between PX and naphtha expanded, and the weak benzene price restricted further increase in PX output. The spread between PX and MX recovered, polyester downstream load remained around 88%, and polyester factory inventory was optimistic. Polyester prices were positive, especially the inventory of filament was well - reduced, sales were optimistic, and profits were significantly repaired. Investors should pay attention to the impact of subsequent device progress on the market and be cautious due to large price fluctuations [2]. - Ethylene Glycol (MEG): There are rumors of a major reform in the domestic petrochemical and refining industries, aiming to phase out small and outdated facilities and shift investment to advanced materials. South Korean naphtha cracking units plan to cut production, leading to a significant increase in olefin varieties. The price of MEG has recovered, overseas MEG device overhauls, especially in Saudi Arabia, have been continuously postponed, which may significantly impact the market. The future arrival volume of MEG will decrease, polyester inventory is acceptable, and downstream weaving load has rebounded [2]. 3) Summary by Relevant Catalogs a) Market Data Changes - **Crude Oil and PTA - Crude Oil Relationship**: INE crude oil price dropped from 493.6 yuan/barrel on August 22, 2025, to 492.9 yuan/barrel on August 25, 2025, a decrease of 0.70 yuan/barrel.

In terms of valuation and cost, PXN was 270 dollars (0), and the naphtha cracking spread was 94 dollars (+ 6). Currently, the PX load remained at a high level, and there were many short - term unexpected maintenance situations for downstream PTA, so the overall load center was relatively low. However, due to the commissioning of new PTA plants, PX was expected to maintain low inventory, and there was support for the valuation at the lower end. Moreover, the terminal and polyester data were gradually improving, releasing the upstream valuation space. The current valuation was at a neutral level, and the terminal and polyester sectors were expected to continue to recover [20] PTA - **Market Quotes**: The PTA01 contract fell 6 yuan to 4,862 yuan, the East China spot price fell 20 yuan/ton to 4,850 yuan, the basis was 22 yuan (0), and the 9 - 1 spread was - 34 yuan (- 14) [22] - **Fundamentals**: The PTA load was 72.9%, down 3.5%.

In terms of valuation and cost, the PTA spot processing fee fell 20 yuan to 228 yuan, and the futures processing fee fell 7 yuan to 334 yuan. In the future, on the supply side, the unexpected maintenance volume in August increased, and the inventory - building pattern changed to inventory - reduction. The PTA processing fee was expected to continue to recover. On the demand side, the inventory pressure of polyester fibers decreased, and the downstream and terminal production start - up rates improved, releasing the upstream valuation space. In terms of valuation, PXN had the momentum to rise supported by the improved situation brought about by PTA commissioning. Recently, the valuation expanded due to the boost from unexpected PTA maintenance. It was recommended to follow PX and go long at low prices after the peak - season downstream performance improved [22] Ethylene Glycol - **Market Quotes**: The EG01 contract rose 35 yuan to 4,509 yuan, the East China spot price rose 24 yuan to 4,542 yuan, the basis was 98 yuan (+ 6), and the 9 - 1 spread was - 59 yuan (- 5) [23] - **Fundamentals**: On the supply side, the ethylene glycol load was 73.2%, up 6.2%.

In terms of valuation and cost, the profit of naphtha - based production was - 384 yuan, the profit of domestic ethylene - based production was - 569 yuan, and the profit of coal - based production was 1,104 yuan. The cost of ethylene remained unchanged at 830 dollars, and the price of Yulin pit - mouth bituminous coal fines decreased to 520 yuan. In terms of industry fundamentals, overseas and domestic maintenance plants were gradually restarting, and the downstream production start - up rate was gradually recovering from the off - season, but the supply was still in excess. It was expected that the port inventory would enter an inventory - building cycle in the medium - term. The valuation was relatively high compared to the same period, the fundamentals changed from strong to weak. Although there was short - term support from less arrival volume and policy sentiment, there was downward pressure on the medium - term valuation [23]
