1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints - The overall macro - sentiment has weakened, and the plastics market is oscillating. The uncertainty of the US - Iran negotiations and the resurgence of geopolitical risk premiums may support oil prices, strengthening the cost support for plastics. The supply of PE is under pressure with high - level开工率 and more imported resources, while the demand is in the off - season. PP's supply pressure is currently acceptable, but the demand is expected to decline seasonally [3][4]. - The current supply - demand structure of PP is still weak, and the cost side fluctuates sharply. For both PE and PP, it is necessary to pay attention to the geopolitical situation and the inventory accumulation amplitude after the Spring Festival [3][4]. 3.
