I. Key Focus Points

1. Market concerns persist regarding the potential escalation of the US-Iran conflict, compounded by Houthi attacks on Saudi Arabia which heighten supply risks; consequently, international crude oil prices have risen.
2. The average operating rate for domestic unsaturated polyester resin (UPR) plants this week was 34.5%, a decrease of 0.5% compared to the previous period.
3. On October 21, total shipments from two tank farms in Zhangjiagang amounted to 1,081 tons, a reduction of 139 tons from the previous day. As of now, combined inventory at Changjiang International and Fubao terminals stands at 17,200 tons.

Core Logic: International crude oil prices are fluctuating at high levels. Continuous restocking by downstream sectors has driven up diethylene glycol (DEG) market trends, resulting in rapid transaction execution.
