1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - The fundamentals of pure benzene and styrene are still weak, with low valuations but high inventories, and the rebound momentum is insufficient. In the short term, they mainly follow the fluctuations of crude oil and are expected to move in a range. It is recommended to take a wait - and - see approach for unilateral trading [4]. 3. Summary by Relevant Catalogs 3.1 Price Forecast and Hedging Strategies - Price Range Forecast: The monthly price range forecast for pure benzene is 5600 - 6200, and for styrene is 6800 - 7400. The current 20 - day rolling volatility of styrene is 29.40%, and its historical percentile in 3 years is 85.8% [3]. - Hedging Strategies: - Inventory Management: For enterprises with high finished - product inventory worried about styrene price decline, they can short styrene futures (EB2511, 25% hedging ratio, entry range 7000 - 7100) and sell call options (EB2511C7100, 50% hedging ratio, entry range 70 - 90) [3]. - Procurement Management: For enterprises with low regular procurement inventory and hope to purchase according to orders, they can buy styrene futures (EB2511, 50% hedging ratio, entry range 6800 - 6850) and sell put options (EB2511P6800, 75% hedging ratio, entry range 120 - 150) [3]. 3.2 Core Contradictions - Supply: In the pure benzene market, two sets of devices in East China postponed their maintenance plans, two long - shut small pure benzene devices in Shandong plan to resume production, and there are import transactions from Europe to China, so the supply is expected to increase in the fourth quarter. For styrene, two new large - scale devices had short - term shutdowns, and the supply continued to tighten in September but is expected to increase monthly after September [4]. - Demand: Downstream production and maintenance coexist in the pure benzene market, and the terminal is likely to have an off - peak season this year, so the pattern of inventory accumulation is difficult to change. The terminal demand for styrene has limited growth, and the pick - up is average [4]. 3.3利多 and利空解读 - 利多 Factors: As of September 22, the port inventory of pure benzene in Jiangsu was 10.7 tons, a month - on - month decrease of 20.15%. Pre - holiday stocking led to destocking of pure benzene ports. In September, two sets of 600,000 - ton styrene devices of Zhejiang Petrochemical were under maintenance, and the supply of styrene continued to tighten [5]. - 利空 Factors: It is heard that there are import transactions from Europe to China in November and December, and the import volume of pure benzene in the fourth quarter is expected to return to a high level. The maintenance plans of some factories' devices in East China were postponed, and two long - shut pure benzene devices in Shandong plan to resume production in mid - October. Two large - scale styrene devices in Jilin Petrochemical and Guangxi Petrochemical are planned to be put into production in the fourth quarter [6][9]. 3.4 Basis and Spread Changes - Basis Changes: - Pure Benzene: The basis of East China - BZ03 on September 23 was - 30, up 36 from the previous day; the basis of East China - BZ04 was 10, up 41 from the previous day [10]. - Styrene: The basis of East China - EB09 on September 23 was 81, down 100 from the previous day; the basis of East China - EB10 was 34, down 34 from the previous day [10]. - Spread Changes: The spreads of pure benzene and styrene in various periods generally showed a downward trend, such as the spot spread of pure benzene decreased by 35 yuan/ton from September 22 to September 23 [11]. 3.5 Industrial Chain Price - Pure Benzene: The prices of pure benzene in various markets and futures contracts generally declined on September 23 compared with the previous day.
