Report Industry Investment Rating - Not provided in the content Core Viewpoints - In the short term, the concentrated arrival of pure benzene in China has led to a rapid increase in port inventories and a weakening of the basis.

Report Industry Investment Rating No relevant information provided. Core Viewpoints - For pure benzene, port inventory declined slightly. Low开工 rates of downstream styrene, CPL, and adipic acid dragged down demand, leading to a weak port basis. The domestic开工 rate of pure benzene decreased at an accelerating pace, and attention should be paid to the impact of European and American sanctions on Russian oil on refinery loads [3]. - For styrene, there were still short - term maintenance plans, and new device launches such as Jihua and Guangxi Petrochemical had an impact. Downstream开工 changed little, but提货 was average, and the finished product inventory pressure of the three major hard plastics remained high, resulting in continuous port inventory pressure [3].
