Report Industry Investment Rating - No specific industry investment rating is provided in the report. Core Viewpoints - The demand for both PE and PP remains weak, which continues to limit their upward potential and is still constrained by supply - side pressure. The recovery of demand is slow, and the cost support is insufficient. For PE, the supply is increasing, and the demand realization rate is slow; for PP, the supply pressure is large, and the profit at a low level restricts its downward space [3]. Summary by Relevant Catalogs Market News and Important Data - **Price and Basis**: L main - contract closed at 7,169 yuan/ton (+27), PP main - contract at 6,898 yuan/ton (+21). LL North China spot was 7,130 yuan/ton (+50), LL East China spot 7,140 yuan/ton (+30), PP East China spot 6,750 yuan/ton (+20). LL North China basis was - 39 yuan/ton (+23), LL East China basis - 29 yuan/ton (+3), PP East China basis - 148 yuan/ton (-1) [1]. - **Upstream Supply**: PE开工率 was 81.8% (+1.5%), PP开工率 was 75.5% (+0.6%) [1]. - **Production Profit**: PE oil - based production profit was 48.7 yuan/ton (-128.7), PP oil - based production profit was - 571.3 yuan/ton (-128.7), PDH - based PP production profit was - 280.6 yuan/ton (-12.9) [1]. - **Import and Export**: LL import profit was - 64.1 yuan/ton (+84.8), PP import profit was - 529.7 yuan/ton (-0.8), PP export profit was 15.0 US dollars/ton (-19.9) [2]. - **Downstream Demand**: PE downstream agricultural film开工率 was 32.9% (+6.1%), PE downstream packaging film开工率 was 52.4% (+0.6%), PP downstream plastic weaving开工率 was 43.9% (+0.3%), PP downstream BOPP film开工率 was 61.4% (+0.0%) [2]. Market Analysis - **PE**: Supply increased as many previously - shut - down plants restarted. Demand improved slightly with pre - holiday stocking, but the demand realization rate was slow, and social inventory decreased slowly. Cost support from international oil prices was insufficient [3]. - **PP**: Supply pressure was large due to expected restart of plants, increased coal - enterprise production, and new capacity release. Demand improved marginally but slowly. Cost was supported by firm propane, and low profit limited the downward space [3]. Strategy - **Single - side**: Neutral for L and PP [4]. - **Inter - period**: L01 - L05 reverse spread; PP01 - PP05 reverse spread [4]. - **Inter - variety**: No strategy provided [4].

Report Industry Investment Rating - Not provided in the content Core Views - For pure benzene, domestic attention is on the commissioning progress of Yulong Cracking Unit 2. There will be concentrated new capacity additions from August to September. Domestic existing unit operations are still stable, while the rhythm of imports has slowed down. Downstream pick - up has reached its peak and declined but remains at a decent level, leading to a decline in port inventory. Downstream operations of pure benzene are recovering from the bottom, but overall operations are still low, and short - term maintenance of styrene has dragged down the rigid demand for pure benzene [3]. - For styrene, downstream pick - up during the peak season remains at a relatively high level, and port inventory is waiting to be further reduced. Currently, the absolute level of port inventory is still high. There will be short - term maintenance in the first and middle of September, leading to a decline in operations, and port inventory has started to decline. However, operations may recover in the second half of September. Among styrene's downstream products, the operations of ABS and PS have slightly declined, EPS operations are decent, and ABS has a large inventory pressure [3]. Summary by Directory 1.

1. Report Industry Investment Rating No information provided. 2. Core View of the Report - The basis of pure benzene at ports has weakened, and the downstream operations of pure benzene have declined to varying degrees. The inventory pressure in the CPL - PA6 - nylon industry chain and the aniline downstream MDI remains high. The pre - peak season (Golden September and Silver October) stocking is below expectations. - For styrene, the port basis rebounded slightly due to end - of - month paper cargo delivery and some traders covering short positions. However, port inventories are continuously accumulating due to high actual operations. If the September styrene maintenance is implemented, it will drag down the demand for pure benzene, and the single - side price will continue to fluctuate weakly. - Among styrene's downstream products, the operations of EPS and ABS have declined again, while PS operations continue to rise. The inventories of the three major hard - plastic products have increased, and the pre - peak season stocking is also below expectations. Styrene production profits are running weakly again [3]. 3. Summary According to Relevant Catalogs 3.1 Pure Benzene and EB's Basis Structure, Inter - Period Spreads - Pure benzene: The main contract basis is - 135 yuan/ton (- 31), and the spot - M2 paper cargo spread is - 50 yuan/ton (+ 0) [1]. - Styrene: The main contract basis is 21 yuan/ton (- 49 yuan/ton) [1]. 3.2 Pure Benzene and Styrene Production Profits, Internal and External Spreads - Pure benzene: The CFR China processing fee is 148 dollars/ton (- 5 dollars/ton), and the FOB Korea processing fee is 132 dollars/ton (- 5 dollars/ton). The US - Korea spread is 51.6 dollars/ton (- 5.0 dollars/ton) [1]. - Styrene: The non - integrated production profit is - 345 yuan/ton (- 15 yuan/ton), and it is expected to gradually shrink [1]. 3.3 Pure Benzene and Styrene Inventories, Operating Rates - Pure benzene: The port inventory is 13.80 million tons (- 0.60 million tons), and the operating rate of downstream products has declined to varying degrees. For example, the caprolactam operating rate is 89.38% (- 2.48%) [1]. - Styrene: The East China port inventory is 179,000 tons (+ 17,500 tons), the East China commercial inventory is 84,000 tons (+ 7,500 tons), and the operating rate is 78.1% (- 0.5%) [1]. 3.4 Styrene Downstream Operating Rates and Production Profits - EPS: The production profit is 337 yuan/ton (+ 0 yuan/ton), and the operating rate is 58.35% (- 2.63%) [2]. - PS: The production profit is - 43 yuan/ton (+ 24 yuan/ton), and the operating rate is 59.90% (+ 2.40%) [2]. - ABS: The production profit is - 115 yuan/ton (+ 18 yuan/ton), and the operating rate is 70.80% (- 0.30%) [2]. 3.5 Pure Benzene Downstream Operating Rates and Production Profits - Caprolactam: The production profit is - 1,710 yuan/ton (+ 50), and the operating rate is 89.38% (- 2.48%) [1]. - Phenol - acetone: The production profit is - 514 yuan/ton (+ 0), and the phenol operating rate is 76.00% (- 2.00%) [1]. - Aniline: The production profit is - 216 yuan/ton (- 12), and the operating rate is 67.55% (- 2.55%) [1]. - Adipic acid: The production profit is - 1,164 yuan/ton (+ 45), and the operating rate is 63.20% (- 2.30%) [1].
