Report Industry Investment Rating No relevant content provided. Core Viewpoints - Korean petrochemical companies may cut 270 - 370 million tons of naphtha cracking capacity, potentially affecting EB supply more than BZ as Korean styrene accounts for 16% of overseas styrene capacity while Korean cracked pure benzene only accounts for 3.5% of overseas pure benzene capacity [3]. - For pure benzene, port inventory is slightly decreasing from a high level but still at a high absolute level, and the port basis is waiting to strengthen further. Attention should be paid to the inventory pressure in the CPL - PA6 - nylon industry chain and the MDI inventory pressure in the aniline downstream [3]. - For styrene, port inventory is accumulating due to high current operating rates, but there are concentrated maintenance plans in September, which may lead to destocking. The operating rates of EPS and PS in the downstream continue to rise, but inventory has not continued to decline, indicating slow downstream follow - up, and ABS maintains a state of high inventory and low operating rate [3].
