Morning Market Brief for Diethylene Glycol

Published on 2026-10-21

I. Key Points

  1. The market continues to assess the prospects for U.S.-Iran dialogue, with concerns over supply risks slightly easing and international crude oil prices declining.
  2. This week, the average operating rate of domestic unsaturated polyester resin (UPR) plants was 35%, an increase of 7 percentage points from the previous period.
  3. On October 19, the total shipment volume from two storage terminals in Zhangjiagang was 1,125 tons. As of now, the combined inventory at Changjiang International and Fubao terminals stands at 19,200 tons.

Core Logic: Sustained increases in international crude oil prices, coupled with continuous restocking by downstream sectors, have driven up diethylene glycol (DEG) market prices, leading to rapid transaction execution.
