乙二醇日报：乙二醇港口去库支撑盘面，关注供给边际修复节奏-20250714

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core View The short - term price of ethylene glycol is expected to maintain a low - level oscillation, and inventory depletion may trigger a rebound. Although it is restricted by cost - end pressure and weak demand, signs of marginal supply - demand repair are emerging. If oil prices do not drop significantly and some coal - chemical plants' maintenance plans are implemented, the price may gradually stabilize. However, for an upward trend, continuous improvement in polyester production and sales is required. Attention should be paid to the implementation of coal - based plant maintenance in August and the rhythm of port inventory changes [3]. 3.
