Weekly Market Outlook for Diethylene Glycol (DEG)

Published on 2026-10-08

I. Key Points

  1. Communication channels between the U.S. and Iran remain open, combined with the possibility of further interest rate hikes by the Federal Reserve, leading to a decline in international crude oil prices.

  2. The average operating rate of domestic unsaturated polyester resin (UPR) plants this week was 28%, down 5% from the previous period.

  3. On September 29, total shipments from two tank farms in Zhangjiagang amounted to 468 tons, a decrease of 68 tons compared to the previous day. As of now, inventory levels at Changjiang International and Fubao tank farms stand at 0.02 million tons.

Core Logic: International crude oil prices continued to fall during the holiday period; market attention is focused on changes in main port inventories.

    With UPR operating rates dropping 5% and crude oil softening, DEG margin pressure is mounting. Low tank farm inventories offer some support, but weak downstream demand keeps sentiment cautious post-holiday.
