纯苯苯乙烯日报：EB基差小幅走强，然而需求跟进仍不及预期-20250828

1. Report Industry Investment Rating - There is no clear industry investment rating provided in the report. 2. Core Views of the Report - For pure benzene, port inventory is declining slightly from a high level, but the absolute level remains high. The port basis is expected to strengthen further. Korean aromatics plants are under maintenance, and the monthly import pressure is not increasing. However, attention should be paid to the large inventory pressure in the CPL - PA6 - nylon产业链 and the MDI inventory pressure in the aniline downstream. The performance during the "Golden September and Silver October" season for downstream industries should be monitored [3]. - For styrene, the port basis rebounded slightly due to some traders covering short positions at the end of the month. However, port inventory is continuously accumulating due to high current operating rates. There will be more maintenance in September, and the rate of destocking in September should be monitored. This will also drag down the demand for pure benzene, so there is limited support for the single - side price. In the downstream of EB, the operating rates of EPS and PS continue to rise, but their inventories do not show further destocking, indicating slow downstream follow - up. ABS maintains a state of high inventory and low operating rate. The performance during the "Golden September and Silver October" season for downstream industries should be monitored [3]. 3. Summary According to the Directory 3.1 Pure Benzene and EB's Basis Structure and Inter - period Spreads - Pure benzene: The main basis is - 104 yuan/ton (- 3), and the spot - M2 spread is - 45 yuan/ton (- 5 yuan/ton). There are also data on the spread between the first - and third - month contracts [1]. - Styrene: The main basis is 70 yuan/ton (+ 2 yuan/ton), and there are data on the spread between the first - and third - month contracts [1]. 3.2 Production Profits and Internal - External Spreads of Pure Benzene and Styrene - Pure benzene: The CFR China processing fee is 150 dollars/ton (- 9 dollars/ton), the FOB Korea processing fee is 135 dollars/ton (- 8 dollars/ton), and the US - Korea spread is 45.6 dollars/ton (- 15.1 dollars/ton). There are also data on import profits [1]. - Styrene: The non - integrated production profit is - 326 yuan/ton (- 48 yuan/ton), and there are data on import profits [1]. 3.3 Inventories and Operating Rates of Pure Benzene and Styrene - Pure benzene: The port inventory is 13.80 million tons (- 0.60 million tons), and the operating rate is not specifically mentioned in the text, but the downstream comprehensive operating rate is relatively high [1]. - Styrene: The East China port inventory is 179,000 tons (+ 17,500 tons), the East China commercial inventory is 84,000 tons (+ 7,500 tons), and the operating rate is 78.5% (+ 0.4%) [1]. 3.4 Operating Rates and Production Profits of Styrene Downstream - EPS: The production profit is 282 yuan/ton (+ 84 yuan/ton), and the operating rate is 60.98% (+ 2.90%) [2]. - PS: The production profit is - 68 yuan/ton (+ 34 yuan/ton), and the operating rate is 57.50% (+ 1.10%) [2]. - ABS: The production profit is - 132 yuan/ton (+ 88 yuan/ton), and the operating rate is 71.10% (+ 0.00%) [2]. 3.5 Operating Rates and Production Profits of Pure Benzene Downstream - Caprolactam: The production profit is - 1760 yuan/ton (+ 45), and the operating rate is 91.86% (- 1.86%) [1]. - Phenol - acetone: The production profit is - 514 yuan/ton (+ 113), and the operating rate is 78.00% (+ 1.00%) [1]. - Aniline: The production profit is - 204 yuan/ton (- 43), and the operating rate is 70.10% (- 1.47%) [1]. - Adipic acid: The production profit is - 1209 yuan/ton (+ 41), and the operating rate is 65.50% (+ 3.80%) [1]. 3.6 Strategies - Single - side: Hold a wait - and - see attitude towards pure benzene and styrene. - Basis and inter - period: Hold a wait - and - see attitude. - Cross - variety: Expand the EB - BZ spread on dips in the short term [4].
