南华苯乙烯产业链周报：纯苯拖累，苯乙烯反弹空间有限-20250929

Report Industry Investment Rating No industry investment rating is provided in the report. Core Viewpoints - The supply of pure benzene is expected to remain high in the fourth quarter due to postponed plant maintenance, the planned return of long - idle small plants, and increased imports from Europe. However, downstream demand is unable to absorb the high supply, leading to a difficult - to - change inventory accumulation pattern. [1][9][20] - For styrene, large - scale plant maintenance has been extended, and multiple operating plants have reduced their loads. Supply tightened in September and is expected to increase in mid - to - late October. From September to November, styrene will maintain a tight balance, but high inventory and the drag from upstream pure benzene limit its upward space. [1] - Macro factors such as the "anti - involution" concept, the Fourth Plenary Session in October, and the 14th Five - Year Plan Outline need attention. When there is no obvious fundamental driver, macro sentiment has a greater impact on the market. [1][10] Summary by Relevant Catalogs Chapter 1: Core Contradictions and Strategy Recommendations 1.1 Core Contradictions - Pure benzene supply is expected to be high in the fourth quarter, while downstream demand is weak, resulting in inventory accumulation. Styrene supply is currently tightening but will increase later, and its upward space is limited by high inventory and pure benzene. [1] 1.2 Trading - Type Strategy Recommendations - The market trend is expected to be range - bound. The BZ2603 is expected to oscillate between 5800 - 6200, and EB2511 between 6800 - 7200. The strategy is to widen the spread between pure benzene and styrene when the EB2511 - BZ2603 spread is around 1000. [13] 1.3 Industry Customer Operation Recommendations - The price range of pure benzene is predicted to be 5600 - 6200, and styrene 6800 - 7400. For styrene, inventory management strategies include short - selling futures and selling call options, while procurement management strategies include buying futures and selling put options. [14] 1.4 Industrial Chain Weekly Data Overview - In terms of price and profit, the prices of various products in the pure benzene - styrene industrial chain have changed to different extents, and the profits of some products have decreased. In terms of supply and demand, the production of some products has increased, while the demand of some downstream products has decreased. [15][16][17] Chapter 2: This Week's Important Information and Next Week's Attention Events 2.1 This Week's Important Information - Positive Information: The government issued a plan to promote the stable growth of the petrochemical industry. Pure benzene port inventory decreased due to pre - holiday stocking. Multiple styrene plants reduced their loads or extended maintenance, further tightening the near - term supply. [19] - Negative Information: Pure benzene imports are expected to increase in the fourth quarter. The maintenance of some pure benzene plants has been postponed, and two long - idle plants are planned to resume production. Two large - scale styrene plants are planned to be put into production in October. [20] 2.2 Next Week's Important Events to Follow - Key economic data such as China's official manufacturing PMI, US ADP employment, ISM manufacturing PMI, unemployment rate, and non - farm payrolls need attention. [21] Chapter 3: Market Interpretation 3.1 Price - Volume and Capital Interpretation - The unilateral price of styrene rebounded after a decline this week, mainly following the fluctuations of crude oil. There was no significant change in the long and short positions in the top five seats of the dragon - tiger list, and the net short position of the main profitable seats increased slightly. [23] - The monthly C - structure of the styrene market flattened. The market interprets the increase in near - term styrene maintenance losses as a negative factor for pure benzene. The spread between pure benzene and styrene has widened, and the strategy is to widen the spread at low levels. [27][30] Chapter 4: Valuation and Profit Analysis 4.1 Industrial Chain Upstream and Downstream Profit Tracking - Analyzes the profits of various links in the industrial chain, including naphtha cracking and reforming, aromatic hydrocarbon blending for oil, pure benzene, and its downstream products, as well as styrene and its downstream products. [32][40][48][53] 4.2 Import and Export Profit Tracking - Analyzes the seasonal patterns of import profits and monthly import volumes of pure benzene and styrene. [58][59] Chapter 5: Supply - Demand and Inventory Projection 5.1 Supply - Side and Projection - Pure Benzene Supply: This week, the production of petroleum benzene and hydro - benzene increased. The maintenance of some plants has been postponed, and imports are expected to increase in the fourth quarter, so the supply is expected to increase. [60] - Styrene Supply: This week, styrene production decreased. Short - term maintenance plans are numerous, and supply will tighten, but it will increase again after new plants are put into production and maintenance plants resume in mid - to - late October. [65] 5.2 Demand - Side and Projection - Pure Benzene Demand: The demand for pure benzene from its five major downstream products has increased due to the resumption of some maintenance plants. [71] - Styrene Demand: The operating rates of EPS and PS among the downstream 3S products have declined, and the demand for styrene has decreased. The future production schedules of household air conditioners and refrigerators have been revised upwards but are still significantly lower than last year, providing little support for styrene demand. [105][106] 5.3 Supply - Demand Balance Sheet Projection - Analyzes the new plant production capacity and supply - demand balance of pure benzene and styrene in 2025, showing that there may be a supply surplus of pure benzene in the fourth quarter and a supply - demand imbalance in styrene.
