Report Summary 1) Report Industry Investment Rating No information provided. 2) Core View of the Report - PTA market: The PTA market is bearish due to weak crude oil prices and news of possible production cuts in downstream polyester bottle chips. Domestic PTA production has slightly decreased due to concentrated breakdowns and maintenance of PTA plants. The spread between PX and naphtha has widened, and the weak benzene price has restricted the further increase of PX production. The spread between PX and MX has recovered, and the downstream polyester load has remained at around 88%. The polyester price has shown a positive trend, especially the inventory of filament has been well reduced, and the production and sales have been continuously optimistic with obvious profit repair. [2] - MEG market: There are rumors that China is planning a major reform of its petrochemical and refining industries, aiming to gradually eliminate small - scale and outdated facilities and shift investment to advanced materials. South Korean naphtha cracking units are planning to cut production, and olefin varieties have risen significantly. The price of ethylene glycol has recovered, and the continuous postponement of overseas ethylene glycol plant maintenance, especially in Saudi Arabia, may have a significant impact on the market outlook. The future arrival volume of ethylene glycol has decreased, the polyester inventory is in good condition, and the downstream weaving load has increased. [2] 3) Summary by Relevant Catalogs Market Data - **Crude Oil and PTA - Crude Oil Relationship**: INE crude oil price increased from 479.7 yuan/barrel on August 27, 2025, to 481.7 yuan/barrel on August 28, 2025.

Report Industry Investment Ratings No relevant content provided. Core Views of the Reports Crude Oil - Overnight oil prices oscillated weakly due to concerns about global crude oil supply surplus and seasonal demand decline. OPEC+ relaxing production cuts and non - OPEC+ countries increasing production led to higher supply expectations. While refinery profits are good currently, the approaching end of the US summer driving season reduces gasoline demand expectations. Geopolitical factors offer some support but the overall market sentiment is bearish, with a high probability of short - term weak oscillation. It is recommended to wait and see on the single - side and look for opportunities to widen spreads on the option side after volatility increases [1]. Polyester Industry - PX: Supply is increasing as检修 devices restart, and downstream PTA has many unplanned shutdowns due to low processing fees. Although the "Golden September and Silver October" demand expectation exists, terminal load declined this week, and the demand support is limited. PX11 should focus on the support around 6800, and the strategy of widening the PX - SC spread should exit at high levels [43]. - PTA: In August - September, supply - demand situation has improved compared to expectations due to more unplanned shutdowns. However, terminal load declined this week, and demand support is limited. TA should focus on the support around 4750 and adopt a rolling reverse spread strategy for TA1 - 5 [43]. - Ethylene Glycol: Domestic supply is increasing as devices resume production, and port inventory is at a low level. With the approaching of the demand peak season, it is expected to oscillate strongly in the short - term. Sellers of the short - put option EG2601 - P - 4350 can hold [43]. - Short - fiber: Supply load remains high, demand is uncertain, and it mainly follows raw material fluctuations. The single - side strategy is the same as PTA, and the processing fee on the disk oscillates between 800 - 1100 with limited upward and downward drivers [43]. - Bottle chips: In August, it is the peak consumption season, and inventory is slowly decreasing. The processing fee has support at the bottom, but it is suppressed by the short - term strengthening of the cost side. The PR single - side strategy is the same as PTA, and the main - contract processing fee on the disk is expected to fluctuate between 350 - 500 yuan/ton [43]. Methanol - Port inventory is increasing significantly, the basis is weak, and imports in September remain high. The supply side has high domestic and rising overseas non - Iranian production. The demand side is weak due to the off - season, but there is an expectation of MTO device restart in September. Future attention should be paid to the inventory inflection point [72][74]. Urea - The rebound of the urea futures is driven by short - term supply contraction due to more device shutdowns for maintenance. Although daily production is still higher than last year, the expected production reduction supports the market. Downstream restocking also strengthens the supply - contraction expectation. However, the market is still in a state of inventory accumulation, and the rebound strength may be limited. Future attention should be paid to device restart progress, port collection, and industrial demand in North China before the parade [85]. Polyolefins - PP: Devices scheduled for restart next week will increase production. The price center is moving down, and the weighted profit is compressed. PP achieves inventory reduction with both supply and demand increasing. - PE: High - level maintenance will continue until September. It shows a stable - to - downward trend. Supply decreases while demand increases, with upstream inventory reduction and mid - stream inventory accumulation. Before mid - September, the overall supply pressure is not large, and the LP01 spread should be held [88]. Chlor - Alkali - Caustic Soda: The futures price is slightly falling, and the previous high - level resistance is obvious. Although the spot market was strong before, with good demand from Shandong's downstream alumina plants and inventory reduction, the supply is expected to increase as some plants resume production. The demand is growing, but the short - term futures pressure may be transmitted to the spot market, and short - selling can be considered [91]. - PVC: The futures price is weakening, and the spot price is also decreasing. Supply is expected to increase as new production capacity is put into use and maintenance decreases. Demand from downstream products is weak, and export pressure increases due to the Indonesian anti - dumping tax. Previous short positions can be held [91]. Pure Benzene - Styrene - Pure Benzene: There is an expectation of supply - demand improvement in the third quarter, but as previous maintenance devices resume and there will be a concentrated arrival of pure benzene at the terminal in the second half of the month, the fundamental advantage is weakening. It oscillates weakly, and BZ2603 should follow the fluctuations of oil prices and styrene [94]. - Styrene: Downstream 3S load declined slightly this week. The industry is in a loss, supply is high, and port inventory is high, so the short - term drive is weak. However, there are more maintenance plans in September - October, and export expectations increase, so the supply - demand situation may improve. EB10 short positions should be closed at low levels, and short - selling on rebounds is recommended [94].

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]. Pure Benzene - Styrene Industry - Pure benzene trends are expected to be weakly volatile, and BZ2603 should follow oil prices and styrene fluctuations. Styrene has a weak short - term drive, and EB10 can be short - sold on rebounds [11]. Urea Industry - The urea market is weakly volatile, with high supply and weak demand. The fundamentals are difficult to reverse [14][15]. Methanol Industry - The methanol market has significant port inventory accumulation, weak basis, and the demand is affected by the off - season. Attention should be paid to the inventory inflection point [18]. Polyolefin Industry - The overall supply pressure of polyolefins is not large before mid - September, and the LP01 spread can be held [44]. Crude Oil Industry - The short - term oil price rebounds, but the geopolitical risks and tariff uncertainties remain. It is recommended to wait and see in the short term [46]. 3. Summaries by Related Catalogs Chlor - Alkali Industry - **Prices**: Shandong 32% liquid caustic soda increased by 1.2%, while the price of East China calcium - carbide - based PVC decreased by 1.1%.

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]

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.
