纯苯苯乙烯日报：淡季下游开工仍偏低-20251121

Report Industry Investment Rating - Not provided Core Views - For pure benzene, low US gasoline inventory supports Asian aromatics through gasoline blending. The arbitrage spread from South Korea to the US has been significantly repaired, potentially easing long - term Chinese arrival pressure, but short - term arrival pressure still exists, with rising port inventory and a weak basis. Domestic production has not further increased after an earlier rise, and downstream开工 remains low. Phenol开工 has increased significantly, while aniline and adipic acid开工 have declined, and styrene is in the maintenance period waiting for recovery at the end of the month [3]. - For styrene, port inventory continues to decline due to export boost and low domestic开工, but there is a resumption expectation at the end of November. Downstream开工 remains low, with EPS开工 rising from a low level but still in the off - season, and ABS and PS开工 slightly rising from a low level, with inventory pressure still existing for PS and ABS [3]. Summary by Relevant Catalogs 1. Pure Benzene and EB's Basis Structure, Inter - Period Spreads - Figures related to pure benzene basis and inter - period spreads include the pure benzene main contract basis, pure benzene spot - M2 paper cargo spread, and pure benzene consecutive first - to - third contract spread [1][15]. - Figures related to EB basis and inter - period spreads include the EB main contract basis and EB consecutive first - to - third contract spread [20]. 2. Pure Benzene and Styrene Production Profits, Domestic - Foreign Spreads - Production profit and spread figures for pure benzene and styrene include naphtha processing fee, pure benzene FOB South Korea - naphtha CFR Japan spread, styrene non - integrated device production profit, and various international price spreads of pure benzene and styrene, as well as their import profits [22][25][34]. 3. Pure Benzene and Styrene Inventory, Operating Rates - For pure benzene, the inventory figure is the East China port inventory, and the operating rate figure is the pure benzene operating rate. For styrene, inventory figures include East China port inventory, East China commercial inventory, and factory inventory, and the operating rate figure is the styrene operating rate [40][42][45]. 4. Styrene Downstream Operating Rates and Production Profits - Downstream products of styrene include EPS, PS, and ABS. Figures cover their operating rates and production profits [51][53][54]. 5. Pure Benzene Downstream Operating Rates and Production Profits - Downstream products of pure benzene include caprolactam, phenol - ketone, aniline, adipic acid, and other related products. Figures cover their operating rates and production profits [60][63][72]. Strategies - Unilateral: None [4]. - Basis and Inter - Period: Conduct long - short inter - period positive arbitrage for EB2512 - EB2601 at low prices [4]. - Cross - Variety: Expand the spread of EB2512 - BZ2603 at low prices [4].
