1. Report Industry Investment Rating No information provided in the content. 2. Core Viewpoints of the Report - BZ futures maintain a certain premium, with strong downstream demand for pure benzene, leading to a decline in pure benzene port inventory from a high level. High开工 rates of styrene and CPL support demand, and the increase in polymer MDI开工 drives up aniline开工. However, the sustainability of high CPL开工 is questionable due to the decline in PA6 and nylon filament开工. On the supply side, the pressure of South Korean exports to China remains, and domestic开工 is still high, resulting in the continued weak consolidation of pure benzene processing fees. - For styrene, port inventory is rising rapidly, and the EB basis is further weakening. Domestically, EB maintains a high开工 rate. In terms of demand, EPS开工 is increasing, but there is still inventory pressure on PS and ABS, suppressing their开工 rates. - The recommended trading strategies are to remain on the sidelines for pure benzene, and to sell short styrene at high prices for hedging. For basis and inter - period spreads, conduct reverse hedging for near - month BZ paper goods against distant - end BZ2603 futures at high prices; conduct reverse inter - period spreads for EB2508 - 2509 and EB2509 - 2510. For cross - variety spreads, narrow the EB - BZ spread at high prices [3]. 3. Summary According to Relevant Catalogs 3.1 Pure Benzene and EB's Basis Structure and Inter - period Spreads - Pure benzene: The main basis of pure benzene is - 202 yuan/ton (+4), and the spread between East China pure benzene spot and M2 is - 85 yuan/ton (+5 yuan/ton). The spread between the first - month contract and the third - month contract is also provided in the figures [1][11]. - Styrene: The main basis of styrene is 116 yuan/ton (- 61 yuan/ton), and the inter - period spreads between EB2508 - 2509 and EB2509 - 2510 are recommended for reverse hedging [1][3]. 3.2 Production Profits and Internal - External Spreads of Pure Benzene and Styrene - Pure benzene: The CFR China processing fee is 160 dollars/ton (+2 dollars/ton), and the FOB South Korea processing fee is 143 dollars/ton (+2 dollars/ton). The price difference between the US and South Korea is 128.9 dollars/ton (- 24.1 dollars/ton). Downstream production profits include - 1818 yuan/ton (+42) for caprolactam, - 667 yuan/ton (+0) for phenol - acetone, - 97 yuan/ton (+74) for aniline, and - 1428 yuan/ton (- 14) for adipic acid [1]. - Styrene: The non - integrated production profit is - 54 yuan/ton (- 87 yuan/ton), and it is expected to gradually compress. The EB - BZ spread is recommended to be narrowed at high prices [1][3]. 3.3 Inventory and Operating Rates of Pure Benzene and Styrene - Pure benzene: The port inventory is 16.40 million tons (- 1.00 million tons), and the开工 rate of downstream products such as caprolactam is 91.72% (- 4.00%), phenol is 81.00% (+3.00%), aniline is 75.86% (+4.96%), and adipic acid is 64.80% (- 0.90%) [1]. - Styrene: The East China port inventory is 138,500 tons (+27,000 tons), the East China commercial inventory is 45,000 tons (+6,000 tons), and the开工 rate is 78.3% (- 0.9%) [1]. 3.4 Operating Rates and Production Profits of Styrene Downstream - EPS production profit is 324 yuan/ton (+119 yuan/ton), and the开工 rate is 53.18% (+2.12%). - PS production profit is - 126 yuan/ton (+69 yuan/ton), and the开工 rate is 50.60% (- 0.50%). - ABS production profit is 490 yuan/ton (+77 yuan/ton), and the开工 rate is 65.90% (+0.90%). The downstream开工 is at a seasonal low [2]. 3.5 Operating Rates and Production Profits of Pure Benzene Downstream - Caprolactam开工 rate is 91.72% (- 4.00%), and the production profit is - 1818 yuan/ton (+42). - Phenol - acetone开工 rate is 81.00% (+3.00%), and the production profit is - 667 yuan/ton (+0). - Aniline开工 rate is 75.86% (+4.96%), and the production profit is - 97 yuan/ton (+74). - Adipic acid开工 rate is 64.80% (- 0.90%), and the production profit is - 1428 yuan/ton (- 14) [1].
