1. Report Industry Investment Rating - Not provided in the given content 2. Core Views - In July, influenced by macro - policies such as "anti - involution and elimination of backward production capacity", black - series coking coal and coke led the rise. Stable - economy policies from meetings boosted the polyolefin futures. After the digestion of positive factors, prices returned to fundamental trading. With multiple new plants coming into operation in July and more to come, the supply - side pressure is high. Currently in the maintenance season, the pressure from new capacity expansion is temporarily offset. OPEC+ production - increase plans dragged down oil prices, weakening cost - side support. Downstream demand is in the seasonal off - season, with limited highlights expected. Mid - and upstream inventories are slowly decreasing, but the total inventory is higher compared to the same period [1][2]. - Domestic new plants: Jilin Petrochemical's 400,000 - ton/year HDPE plant and Yulong Petrochemical's 500,000 - ton/year PP plant were successfully put into operation in July. Many other plants are waiting to start production, indicating continuous growth in domestic polyolefin new - plant capacity. For domestic existing plants, PE maintenance losses are at a high level year - on - year, some PDH plants have restarted, and PDH - made PP plant maintenance has decreased. Overseas, no new plants were put into operation in July, and overseas under - construction plants face many uncertainties and delays may be common. Overseas PE and PP operating rates have decreased slightly. The LLDPE import window is closed, and China's PE and PP imports are continuously decreasing [2]. - In terms of inventory and demand, downstream demand for polyolefins remains in the seasonal off - season, with factories mainly making rigid purchases. The operating rate of PE's downstream agricultural film has a slight rebound, while the demand for packaging film is weak. The operating rate of PP's downstream woven products fluctuates slightly. The demand side is expected to remain weak. Mid - and upstream polyolefin inventories are slowly decreasing, but the total inventory is higher year - on - year [2]. 3. Strategies - Unilateral: Neutral [3] - Inter - delivery: L09 - L01 reverse spread, PP09 - PP01 reverse spread [3] - Inter - variety: Narrow the spread between PP2601 and 3MA2601 [3] 4. Summary by Relevant Catalogs 4.1 Polyolefin Basis Structure - The report provides charts of the main contract trends, basis, and inter - delivery spreads of LL and PP, including LL North China - main contract basis, L1 - L5, L5 - L9, L9 - L1 for LL, and PP East China - main contract basis, PP1 - PP5, PP5 - PP9, PP9 - PP1 for PP [15]. 4.2 Polyolefin Production Plan - Domestic: Multiple plants have been put into operation in 2025, and many are waiting to start production, such as ExxonMobil Huizhou's 500,000 - ton/year LDPE plant. The total planned production capacity of new domestic plants is large, indicating continuous growth in domestic supply [18][20]. - Overseas: Some plants were put into operation in 2025, and many are in the un - started state. Overseas under - construction plants face many uncertainties, and delays may be common [22]. 4.3 Polyolefin Maintenance Plan - PE: The maintenance season of PE plants has ended, and maintenance losses have increased.

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - The market should focus on compressing the profit position of styrene. Pure benzene supply and demand are both increasing, while styrene supply is increasing and demand is decreasing. Currently, styrene is in a pattern of high production, high profit, and high inventory, and it is mainly considered for short - selling. The port inventory of styrene is in an accelerated accumulation stage. The downstream operating rate of pure benzene is gradually recovering, and the industry is gradually entering the inventory replenishment stage. The short - term market still has support at 5600 - 5700. [3] 3. Summary According to Related Catalogs 3.1 Pure Benzene and Styrene Market Supply - Domestic pure benzene: The planned maintenance loss in July was about 90,000 tons, which decreased to 40,000 tons in August, and the planned maintenance in September was 70,000 tons. New pure benzene plants will be put into operation intensively from July to September. [3] - Imported pure benzene: The price of pure benzene in the US has stabilized and rebounded. The profit of STDP plants is negative, and the output rate is still decreasing. The profit of US styrene has been squeezed from a high level, but the operating rate has recovered from 50% in June to nearly 65% - 70% in July. The arbitrage window for styrene from the US to Europe has closed, and the incremental demand in August is expected to come from South America. [3] Demand - Styrene: There has been a large increase in supply recently. New plants such as Jingbo Petrochemical (680,000 tons, put into operation in early August) and Jilin Petrochemical (600,000 tons, put into operation on September 20) are about to be launched. [3] - Caprolactam: It was in a state of increasing load in July, and some plants plan to reduce the load after August. A new 300,000 - ton plant of Hengyi in Guangxi Qinzhou is planned to be put into operation in October. [3] - Phenol: Zhenhai Refining & Chemical's 400,000 - ton plant was put into operation in July, Jilin Petrochemical's plant will be put into operation in late August, and Shandong Ruilin plans to put it into operation in October. [3] - Aniline: Some plants such as Jinmao Aluminum and Chemical, Shandong Huatai, and Jiangsu Fuqiang have recently restarted, and Wanhua Chemical (Fujian)'s new plant has been put into operation and is currently operating at a low load. Yantai Wanhua plans to conduct rotational maintenance from August to September. [3] - 3S hard plastics downstream of styrene: EPS and PS have clearly entered the summer off - season, with continuous inventory accumulation and reduced operating rates. The overall demand for ABS remains medium - high and shows resilience. [3] Valuation - The reasonable valuation of pure benzene 2603 is 6000 yuan/ton. The current styrene futures price structure has turned to contango, and the largest structural opportunity this year is approaching the end. [3] Strategy - Unilateral: Short on rallies. - Inter - period: Temporarily take profit on cash - and - carry arbitrage and reverse cash - and - carry arbitrage in the futures market. - Inter - commodity: Buy BZ03 and sell EB09, and take profit on the position of compressing profit temporarily. [3] 3.2 Pure Benzene Delivery Standards - The overall delivery settings are uniform. The benchmark delivery areas are Jiangsu, Zhejiang, and Shanghai. Different regions have different premium and discount settings. [5] Production Capacity - The production capacity of pure benzene before 2005 was 3.26 million tons, accounting for 12%. [20] Market Situation in 2025 - In the first half of 2025, the price continued to decline, mainly due to pre - Spring Festival market over - speculation and the non - implementation of downstream production capacity expansion expectations. In the second half of the year, domestic supply continued to increase, but it gradually entered the de - stocking pattern. From January to May 2025, the total output of pure benzene was 8.97 million tons, a year - on - year increase of 6%. It is expected that the apparent demand for pure benzene in 2025 will be 31.39 million tons, a year - on - year increase of 8.9%. [30] 3.3 Styrene Production Capacity - The production capacity of styrene before 2005 was 1.12 million tons, accounting for 5%. [21] Market Situation in 2025 - The global styrene output contracted in the first half of 2025. Currently, styrene is in a pattern of high inventory, medium - level profit (recently compressed). [70][76] Future Outlook - Pay attention to the issue of the price ratio between aromatics and olefins. Styrene in the far - month should not have profit. [69][81] 3.4 Downstream Products of Pure Benzene Phenol - It is expected that the apparent demand for phenol in 2025 will be 6 million tons, a year - on - year increase of 7%. [52] Caprolactam - It is expected that the apparent demand for caprolactam in 2025 will be about 7 million tons, a year - on - year increase of 7%. [55] Adipic Acid - The annual apparent demand for adipic acid is about 1.9 million tons, a year - on - year decrease of 7%. [57] Aniline - It is expected that the apparent demand for aniline in 2025 will remain at 3.61 million tons, a year - on - year decrease of 8%. [61]

In July, there were plans to put into operation the fourth line of Yulong Petrochemical and the first line of Ningbo Daxie Petrochemical for PP, and the second - phase HDPE of Jilin Petrochemical. The overall supply pressure was increasing. The off - season demand lacked support, and downstream buyers mostly maintained a low - inventory strategy. The supply - demand margin was deteriorating, and the market showed a unilateral downward trend [6]. Group 4: Industry News - On July 8, 2025, the inventory level of major producers was 780,000 tons (yesterday's inventory was revised to 790,000 tons), a decrease of 10,000 tons from the previous working day, a decline of 1.27%. The inventory in the same period last year was 780,000 tons [7]. Group 5: Data Overview - The report includes data on L basis, PP basis, L - PP spread, crude oil futures main contract settlement price, two - oil inventories, and two - oil inventory year - on - year increase/decrease rate, with data sources from Wind and Zhuochuang Information [9][16][17]

Report Title - Benzene Ethylene Weekly Report: EB: Supply-demand margin weakens, inventory stops falling, focus on raw material resonance opportunities [1] Report Industry Investment Rating - Not provided Core Viewpoints - Although there is a strong expectation of OPEC+ production increase, the macro - environment is stable, and the peak season boosts, so oil prices maintain a volatile trend. On the pure benzene side, both domestic supply and demand increase, but supply increases more than demand. Due to the non - opening of the America - Asia arbitrage window and the successive return of maintenance devices in Japan and South Korea, high imports are expected to continue. The destocking of pure benzene port inventory is difficult, with relatively large year - on - year pressure, which drags down the styrene price. For styrene, weekly supply increases while demand decreases. Some upstream devices will resume production in June, and some downstream sectors enter the off - season. There are pressures in terms of profit and inventory on the 3S side, so it is difficult to effectively drive the styrene price. Styrene inventory stops falling and accumulates this week, and is expected to enter a volatile stage, mainly focusing on the absolute year - on - year level. Currently, the estimated valuation of styrene is still high. Considering the fundamentals of pure benzene, the valuation regression probably requires a downward correction of styrene. Therefore, maintain a short - selling idea for styrene, pay attention to raw material resonance opportunities in terms of rhythm, and be vigilant against macro risks [3] Strategy Recommendations Futures Strategy - Maintain a short - selling idea for styrene, with the upper resistance level for the near - month contract at 7400 [4] Option Strategy - Sell EB2507 - C - 7500 [4] Summary by Directory Pure Benzene 2025 Production and Investment Plan - Multiple companies in different provinces have plans for pure benzene, styrene, and their downstream products in 2025. For example, Yulong Petrochemical in Shandong has a 100 - million - ton pure benzene production plan from 2024Q4 - 2025 and a 50 - million - ton styrene production plan in 2025Q1 [6] 2025 May - July Device Dynamics - Many companies' devices have maintenance plans from May to July 2025, such as Hubei Jin'ao's device, which stopped for maintenance on March 11 and is expected to restart in mid - May [8] Supply, Demand, and Inventory - From May to July 2025, the planned new pure benzene production capacity is about 1.33 million tons/year, and the downstream new production capacity is about 400,000 tons/year. The planned pure benzene shutdown involves a production capacity of 4.46 million tons/year, and the downstream shutdown production capacity is about 5.89 million tons/year. The net supply reduction is about 239,000 tons, and the net demand reduction is about 341,000 tons. Overall, inventory is expected to accumulate [9] Price and Profit - The prices of pure benzene in different regions and the price differences between different regions are presented in the report. The toluene disproportionation profit is relatively low [15] Downstream Situation - The weighted downstream operating rate of pure benzene has recently declined slightly. The styrene profit has rebounded significantly, while the profits of other products are still weak [36][43] Styrene and Its Downstream Spot and Futures - The spot price, basis, and monthly spread of styrene are presented in the report [53] Supply - The monthly and weekly production, operating rate, and profit of styrene are shown. Asia has multiple styrene device exits, and China is gradually changing from a net importer to a net exporter of styrene [58][70] Inventory - Styrene port inventory has stopped falling and continued to accumulate [71] Downstream Situation - The 3S production capacity growth rate is high, intensifying industry competition. The estimated weekly styrene consumption converted from 3S production has decreased. The downstream prices have weakened, and the profits are under pressure. The high - production inventory is higher year - on - year, indicating possible demand transmission resistance. After the implementation of tariffs, exports are likely to be restricted, and domestic demand should focus on subsidy stimulation [76][81][92]
