Report Investment Rating - The investment rating for the industry is neutral [3] Core Viewpoints - The main driver of major aromatic hydrocarbon varieties lies in the upstream crude oil. Attention should be paid to the geopolitical conflicts and subsequent oil price fluctuations, which will impact the costs of pure benzene and styrene. The domestic production rate of pure benzene has reached a high level, while the downstream CPL production rate has further declined, dragging down the demand for pure benzene. The US-South Korea window for pure benzene remains closed, and there is still significant pressure for shipments to China. The port inventory of pure benzene has continued to rise, and the processing fee for pure benzene is weak. For styrene itself, the arrival rhythm has slowed down, leading to a slight decrease in port inventory. Although the absolute amount of port inventory is still low, the port basis is firm. In the medium to long term, with the gradual increase in styrene production, there is an expectation of factory inventory accumulation. Downstream, the inventory of PS and ABS still faces pressure, and the production rate is also mediocre [2] Summary by Directory EB& Pure Benzene Basis Structure and Related Spreads - The report presents multiple figures related to EB and pure benzene basis structure and spreads, including EB main contract trends and basis, EB main contract basis, styrene consecutive one - consecutive three contract spreads, styrene non - integrated device production profit, styrene spot import profit, East China pure benzene spot - M2 paper cargo spread, pure benzene CFR China - naphtha spread, pure benzene FOB US Gulf - pure benzene FOB South Korea, and China pure benzene spot import profit [6][9][10] EB& Pure Benzene Production and Inventory - Figures show the East China port inventory of pure benzene, the production rate of pure benzene, the East China port inventory of styrene, the production rate of styrene, the East China commercial inventory of styrene, and the factory inventory of styrene [25][27][30] Downstream Production Rate and Production Profit - The report includes figures on the production rate and production profit of downstream products such as EPS, PS, and ABS [42][44][45] Pure Benzene Downstream Production Profit - Figures display the production profit of various pure benzene downstream products, including caprolactam, phenol - acetone, aniline, adipic acid, PA6 regular spinning bright, nylon filament, bisphenol A, PC, epoxy resin E - 51, pure MDI, and polymer MDI [47][52][54]
