苯乙烯日报：EB基差进一步走弱-20250716

1. Report Industry Investment Rating - No specific industry investment rating is provided in the report. 2. Core Viewpoints of the Report - BZ futures discount has narrowed, and the strong downstream demand for BZ has led to a decline in pure benzene port inventory from a high level. The high operating rates of downstream styrene and CPL support the demand, and the increase in polymer MDI operating rate drives up the aniline operating rate. However, the sustainability of CPL's high operating rate is still questionable due to the decline in PA6 and nylon filament operating rates. On the supply side, the pressure of South Korea's exports to China remains, and domestic production operating rates are still high, resulting in the continued weak consolidation of pure benzene processing fees. For styrene, port inventory has further increased, and the EB basis has rapidly declined. Domestically, EB maintains a high operating rate on the supply side, while on the demand side, the operating rates of EPS and PS drag down EB demand [3]. 3. Summary According to the Directory I. Pure Benzene and EB's Basis Structure, Inter - Period Spreads - The report mentions various basis and spread data of pure benzene and EB, including pure benzene's main basis, the spread between pure benzene spot and M2 paper goods, the spread between the first - and third - continuous contracts of pure benzene, EB's main contract basis, and the spread between the first - and third - continuous contracts of styrene [1][13][19]. II. Pure Benzene and Styrene Production Profits, Domestic and Foreign Spreads - Data on production profits and domestic - foreign spreads of pure benzene and styrene are presented, such as naphtha processing fees, the difference between pure benzene FOB South Korea and naphtha CFR Japan, non - integrated production profits of styrene, and differences in FOB prices of pure benzene and styrene in different regions [25][26][37]. III. Pure Benzene and Styrene Inventory, Operating Rates - Pure benzene port inventory is 16.40 million tons (-1.00 million tons), and styrene's East China port inventory is 138,500 tons (+27,000 tons), and its East China commercial inventory is 45,000 tons (+6,000 tons). The operating rate of pure benzene downstream products and styrene is also given, like the operating rate of styrene is 79.2% (-0.8%) [1]. IV. Styrene Downstream Operating Rates and Production Profits - For styrene downstream hard plastics, EPS production profit is 310 yuan/ton (+198 yuan/ton), PS production profit is -190 yuan/ton (+98 yuan/ton), ABS production profit is 408 yuan/ton (+109 yuan/ton). The operating rates of EPS, PS, and ABS are 51.06% (-4.82%), 51.10% (-1.30%), and 65.00% (-0.04%) respectively, and the downstream operating rates are at a seasonal low [2]. V. Pure Benzene Downstream Operating Rates and Production Profits - Data on the operating rates and production profits of pure benzene downstream products are provided, such as the operating rate of caprolactam is 95.72% (+0.00%), the production profit of caprolactam is -1,895 yuan/ton (-5 yuan/ton), etc. [1]. 4. Strategies - Unilateral: Hold a wait - and - see attitude towards pure benzene and styrene [4]. - Basis and Inter - period: For the near - month BZ paper goods - distant BZ2603 futures, conduct reverse arbitrage when the price is high [4]. - Cross - variety: Narrow the EB - BZ spread when it is high [4].
