纯苯苯乙烯日报：纯苯港口库存回落，但基差表现仍弱-20251028

Report Industry Investment Rating - Not mentioned in the provided content Core Viewpoints - Pure benzene port inventory has declined again, but the basis performance remains weak due to weak downstream demand, with varying degrees of decline in the开工 rates of styrene, CPL, and adipic acid. The domestic开工 rate of pure benzene has decreased at an accelerating pace, and the pure benzene load of some refineries in Shandong and Ningbo has been affected by the sanctions on Russian oil by Europe and the United States [3]. - For styrene, there are still short - term maintenance plans, and new device launches such as Jihua and Guangxi Petrochemical have an impact. Downstream开工 changes little, but the提货 performance is average, and the finished product inventory pressure of the three major hard plastics remains high, so the port inventory pressure of EB persists, waiting for further loss - driven production cuts [3]. Summary by Directory I. Pure Benzene and EB's Basis Structure, Inter - period Spread - Figures related to the basis and inter - period spread of pure benzene and EB are presented, including the basis of pure benzene and EB main contracts, the spread between pure benzene spot and M2 paper cargo, and the spread between the first and third contracts of pure benzene and EB [8][12][19] II. Pure Benzene and Styrene Production Profits, Internal and External Spreads - Figures show the processing fees of naphtha, the spread between pure benzene FOB Korea and naphtha CFR Japan, the production profit of non - integrated styrene devices, and various internal and external spreads of pure benzene and styrene [22][25][31] III. Pure Benzene and Styrene Inventory, Operating Rates - Figures display the inventory and operating rates of pure benzene and styrene, including the East China port inventory, commercial inventory, factory inventory of styrene, and the East China port inventory and operating rate of pure benzene [42][44][47] IV. Styrene Downstream Operating Rates and Production Profits - Figures show the operating rates and production profits of EPS, PS, and ABS, which are the downstream products of styrene [53][55][58] V. Pure Benzene Downstream Operating Rates and Production Profits - Figures present the operating rates and production profits of pure benzene downstream products such as caprolactam, phenol - ketone, aniline, and adipic acid, as well as the production profits of related products like PA6, nylon filament, bisphenol A, etc. [63][66][77] Strategy - Unilateral: None - Basis and inter - period: None - Cross - variety: Short - term strategy is to expand the spread of pure benzene processing fees (pure benzene - naphtha) when it is low [4]
