1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - For crude oil, although the geopolitical premium has disappeared and OPEC's production increase is minimal with supply not yet surging, short - term oil prices are not easy to be overly bearish. A low - buying and high - selling range strategy is maintained, but it is recommended to wait and see for now to test OPEC's export price - support willingness [3]. - For methanol, the peak - season demand has fallen short, and the pattern of high domestic inventory and weak reality remains. Due to the delay in the unloading of imported goods, the port pressure has eased. Future upward price drivers may come from the expectation of winter gas restrictions. It is recommended to wait and see [5]. - For urea, the domestic market lacks effective positive factors, but the price is at a low level with low valuation. It is expected to fluctuate in a narrow range, and it is recommended to wait and see or consider long - position opportunities at low prices [8]. - For rubber, the rubber price has stabilized in the short term. It is recommended to set a stop - loss for short - term long positions and enter and exit quickly. Partial position - building is suggested for the hedging strategy of buying RU2601 and selling RU2609 [15]. - For PVC, the domestic supply is strong and demand is weak, with a poor export outlook. It is recommended to pay attention to short - selling opportunities in the medium term [18][20]. - For pure benzene and styrene, the styrene price may stop falling in stages as the port inventory is being reduced significantly during the seasonal peak season [23]. - For polyethylene, the price is expected to remain in low - level fluctuations as the long - term contradiction shifts to the South Korean ethylene clearance policy [26]. - For polypropylene, in the context of weak supply and demand and high inventory pressure, the cost - side oversupply pattern suppresses the market [29]. - For PX, there is currently a lack of driving factors, and PXN is difficult to expand actively. It is recommended to wait and see [30]. - For PTA, the supply is increasing slightly, and the demand shows signs of weakness. It is recommended to wait and see [31]. - For ethylene glycol, the industry is expected to continue to accumulate inventory in the fourth quarter, and it is recommended to short - sell on rallies [33]. 3.

1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - This month, the Shanghai Composite Index reached a ten - year high, and the macro sentiment improved, but it still couldn't stop the decline in styrene prices. With the decrease in the pure benzene - naphtha (BZN spread) and the increase in the profit of EB non - integrated plants, the overall valuation is moderately high. Under the situation of a wide supply of pure benzene, styrene production has increased. Although the seasonal peak season is approaching and the downstream three - S production has rebounded slightly, due to the weak supply - demand situation, the inventory in factories and ports has increased significantly, with weak upward support. In the short term, styrene is expected to fluctuate with a downward bias. The recommended strategy is to hold short positions [11]. 3. Summaries According to the Directory 3.1 Monthly Assessment and Strategy Recommendation - **Policy and Market**: The Shanghai Composite Index reached a ten - year high this month, but styrene prices still fell [11]. - **Valuation**: Styrene showed a monthly decline (spot > futures > cost), with the basis weakening, the BZN spread weakening, and the profit of EB non - integrated plants weakening [11]. - **Cost**: The price of East China pure benzene fell by - 3.86% this month, and the pure benzene operation rate was moderately high. In July, the domestic pure benzene import volume was 5078800 tons, a 43.24% increase from June and a 45.27% increase from last year, mainly from the Middle East [11]. - **Supply**: The EB capacity utilization rate was 79.7%, a 2.53% increase from the previous month, a 14.84% increase from last year, and a 5.42% increase compared to the same period in the past five years. According to the production plan, there are fewer production plans in the third quarter and more maintenance in September, and the greatest production pressure for the whole year is in the fourth quarter [11]. - **Import and Export**: In July, the EB import volume was 221000 tons, a 0.26% increase from June and an 18.45% increase from last year. With the reduction of the Middle East geopolitical conflict, the import volume has recovered [11]. - **Demand**: The weighted operation rate of the downstream three - S was 42.73%, a - 2.53% decrease from the previous month; the PS operation rate was 61.00%, a 1.84% increase from the previous month and an 18.24% increase from last year; the EPS operation rate was 52.52%, a - 9.98% decrease from the previous month and a - 4.73% decrease from last year; the ABS operation rate was 69.00%, a - 2.54% decrease from the previous month and a 10.58% increase from last year. As the seasonal peak season approaches, the operation rate will fluctuate and rise at a low level [11]. - **Inventory**: The in - factory EB inventory was 214900 tons, a 1.61% increase in inventory from the previous month and a 28.62% increase compared to the same period last year; the EB inventory at Jiangsu ports was 196500 tons, a 23.58% increase in inventory from the previous month and a 568.37% increase compared to the same period last year. The significant increase in port inventory has severely suppressed the futures price [11]. - **Next - Month Forecast**: For styrene (EB2510), the reference fluctuation range is (6900 - 7200) [11]. - **Recommended Strategy**: It is recommended to hold short positions [11]. 3.2 Futures and Spot Market - The EB continuous 1 - continuous 2 spread is oscillating at the bottom.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Capital market sentiment is relatively hot, chemical stock valuations are being repaired upwards, and crude oil prices are oscillating at a low level. The overall profit of polyolefins has declined, and the high inventory in the upstream and midstream has started to decrease. The main contradiction in the polyolefin fundamentals lies in the divergence in the supply side of the 2601 contract. Polyethylene only has a planned production capacity of 400,000 tons, while polypropylene faces greater pressure with a planned production capacity of 1.45 million tons. With the approaching of the seasonal peak season, it is expected that the LL - PP price difference will continue to strengthen in an oscillating manner [17]. - The recommended strategy is to go long on the LL - PP price difference at low levels [17]. 3. Summary According to the Directory 3.1 Monthly Assessment and Strategy Recommendation - **Valuation**: Capital market sentiment is hot, chemical stock valuations are being repaired upwards, and crude oil prices are oscillating at a low level. Polyolefin overall profit declines, and upstream and midstream high - level inventory starts to decrease [17]. - **Cost**: WTI crude oil dropped by - 1.83% this month, Brent crude oil dropped by - 0.06%, coal price dropped by - 1.72%, methanol dropped by - 6.02%, ethylene dropped by - 6.92%, propylene rose by 7.37%, and propane rose by 12.52%. Oil prices are oscillating at a low level, and the impact on the cost side is small. This month's trading logic in the futures market is strongly influenced by macro - sentiment [17]. - **Supply**: PE capacity utilization rate is 81.09%, a month - on - month decrease of - 4.05%, a year - on - year increase of 2.08%, and a decrease of - 11.00% compared with the five - year average. PP capacity utilization rate is 80.02%, a month - on - month increase of 3.04%, a year - on - year increase of 5.78%, and a decrease of - 5.99% compared with the five - year average. There is a divergence in the supply side of the polyolefin 2601 contract. Polyethylene only has a planned production capacity of 400,000 tons, while polypropylene has greater pressure with a planned production capacity of 1.45 million tons [17]. - **Import and Export**: In July, domestic PE imports were 1.107 million tons, a month - on - month increase of 15.40% and a year - on - year decrease of - 14.78%. PP imports were 177,200 tons, a month - on - month decrease of - 12.73% and a year - on - year decrease of - 12.73%. On the export side, it declined in the off - season. In July, PE exports were 101,700 tons, a month - on - month increase of 5.03% and a year - on - year increase of 76.67%. PP exports were 236,100 tons, a month - on - month increase of 12.73% and a year - on - year increase of 65.78% [17]. - **Demand**: The downstream operating rate of PE is 40.5%, a month - on - month increase of 3.53% and a year - on - year decrease of - 5.86%. The downstream operating rate of PP is 49.90%, a month - on - month increase of 2.04% and a year - on - year decrease of - 0.12%. The seasonal peak season is approaching, but the overall operating rate is lower than that of previous years, with PP performing better than PE [17]. - **Inventory**: PE production enterprise inventory is 450,800 tons, with a destocking of - 12.53% this month and a stockpiling of 2.11% compared with the same period last year. PE trader inventory is 58,500 tons, with a destocking of - 4.36% compared with last month and a destocking of - 2.07% compared with the same period last year. PP production enterprise inventory is 581,900 tons, with a destocking of - 0.89% this month and a stockpiling of 10.17% compared with the same period last year. PP trader inventory is 193,000 tons, with a stockpiling of 3.04% compared with last month and a stockpiling of 50.43% compared with the same period last year. PP port inventory is 58,500 tons, with a destocking of - 4.26% compared with last month and a destocking of - 13.59% compared with the same period last year [17]. - **Next - Month Forecast**: The reference oscillation range for polyethylene (L2601) is (7,200 - 7,500); the reference oscillation range for polypropylene (PP2601) is (6,900 - 7,200) [17]. - **Strategy Recommendation**: Go long on the LL - PP price difference at low levels [17]. 3.2 Futures and Spot Market - Due to the mismatch in the production plans of the 2601 contract, go long on the LL - PP price difference at low levels [65]. 3.3 Cost Side - Crude oil prices are oscillating downward. The prices of various raw materials such as WTI crude oil, Brent crude oil, coal, methanol, ethylene, propylene, and propane have different trends. The profit from ethylene - based PE production has declined significantly. The import freight of LPG oscillates upward seasonally [85][93][119]. 3.4 Polyethylene Supply Side - The production raw materials of PE include oil - based, coal - based, methanol - based, and light - hydrocarbon - based, with different proportions. In 2025, multiple PE production projects have been put into operation, with a total of 4.63 million tons of production capacity put into operation and 400,000 tons yet to be put into operation. The capacity utilization rate of PE shows certain fluctuations, and there are also corresponding maintenance plans [142][148][154]. 3.5 Polyethylene Inventory and Import - Export No detailed analysis content is provided in the text, only the figures of total inventory and production enterprise inventory are mentioned [158].
