Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Pure Benzene: Short - term spot liquidity is tightening due to fewer imported shipments and potential unloading issues. In the long - term, domestic and imported supplies are expected to increase, leading to a high - supply situation in the fourth quarter that downstream industries can't fully absorb, and the inventory build - up pattern is hard to change [4]. - Styrene: Supply is tightening as more units are under maintenance and the return of Jingbo's styrene is uncertain. However, terminal demand recovery after the National Day holiday is limited, and port inventory remains high. With new plants coming into operation, the de - stocking pressure is expected to increase. In the short term, one can short the spread between pure benzene and styrene when prices are high, and consider widening the processing spread after seeing significant unplanned styrene production cuts or an increase in pure benzene imports. Given the large macro - level disturbances, it is advisable to take a wait - and - see approach for unilateral trading [4]. 3. Summary by Related Catalogs 3.1 Price Forecast and Hedging Strategies - Price Forecast: The monthly price range for pure benzene is predicted to be 5200 - 5800 yuan/ton, and for styrene, it is 6200 - 6800 yuan/ton. The current 20 - day rolling volatility of styrene is 29.40%, and its historical percentile over three years is 85.8% [3]. - Hedging Strategies: - Inventory Management: For high product inventories and concerns about price drops, one can short styrene futures (EB2512) at 25% with an entry range of 6600 - 6650 yuan/ton to lock in profits and cover production costs. Also, sell call options (EB2512C6700) at 50% with an entry range of 70 - 90 to collect premiums and reduce capital costs [3]. - Procurement Management: For low procurement inventories and the need to purchase based on orders, buy styrene futures (EB2512) at 50% with an entry range of 6350 - 6400 yuan/ton to lock in procurement costs. Sell put options (EB2512P6400) at 75% with an entry range of 55 - 70 to collect premiums and reduce procurement costs [3]. 3.2 Core Contradictions - Pure Benzene: Short - term supply tightness due to import issues, but long - term high supply and difficult de - stocking due to insufficient downstream demand [4]. - Styrene: Supply reduction due to maintenance, but limited demand recovery and high port inventory. New plant startups will increase de - stocking pressure. Macro factors drive price increases, but the rebound is weaker than that of crude oil [4]. 3.3利多解读 (Positive Factors) - In early October, South Korea's exports of pure benzene to China decreased to 4.7 tons, and some import cargoes faced unloading difficulties, tightening short - term spot liquidity [5]. - Dalian Hengli Petrochemical's 720,000 - ton styrene plant is planned to shut down for half a month starting in early November [7]. - US sanctions on Russian oil companies and geopolitical rumors in Venezuela have pushed up crude oil prices, strengthening the cost side [7]. 3.4利空解读 (Negative Factors) - As of October 20, 2025, the styrene port inventory in Jiangsu was 202,500 tons, an increase of 6,000 tons from the previous period, indicating difficulty in reducing high inventory [8]. - The 600,000 - ton styrene plants of Guangxi Petrochemical and Jilin Petrochemical were put into production around October 18 and 19 respectively [8]. 3.5 Price and Spread Data - Basis Changes: The daily basis changes of pure benzene and styrene in different regions and contracts are provided, showing various trends [8]. - Industry Chain Spreads: The spreads between pure benzene and styrene in the industry chain, including spot, paper - based, and different contract months, are presented, along with their daily changes [9]. - Price Data: The prices of various products in the pure benzene - styrene industry chain, such as crude oil, naphtha, ethylene, pure benzene, and styrene, are given for different dates, including daily and weekly changes [9][10].
