I. Key Points

  1. Mediators continue to push forward US-Iran peace talks, leading to a decline in international crude oil prices. However, unresolved conflict risks have limited the extent of the drop.
  2. This week, the average operating rate of domestic unsaturated polyester resin (UPR) plants was 35%, an increase of 0.5% from the previous period.
  3. On October 28, total shipments from two storage zones in Zhangjiagang reached 1,018 tons, a decrease of 154 tons compared to the previous day. As of now, combined inventory at Changjiang International and Fubao terminals stands at 9,800 tons.

Core Logic: International crude oil prices remain high; trading momentum for diethylene glycol (DEG) has slowed at elevated levels; end-of-month vessel cargo arrivals are concentrated into inventory.

II. Price Table

Category Product Region/Unit Previous Period Price Current Period Price Change Rate
Crude Oil WTI USD/barrel 102.78 102.00 -0.76%

Diethylene Glycol Domestic East China 7,780 7,730 -0.64%

Notes:

  1. All product prices refer to National Standard Premium Grade.
  2. Crude oil is quoted in USD/barrel; other three products are quoted in CNY/ton.
  3. All CNY prices in the table above are ex-warehouse, foreign exchange settlement inclusive, tax-inclusive prices.
  4. Change rate refers to period-over-period fluctuation.

III. Market Outlook

According to Chempricehub on October 30: Downstream bulk replenishment is nearing its end, with reduced acceptance of higher price levels. Trading activity relaxed towards the end of the month, indicating insufficient effective demand stimulus for DEG. The market trend towards consolidation is strengthening, suggesting potential downward correction in subsequent periods.

    Crude dip from US-Iran talks barely eased DEG feedstock costs, keeping UPR margins thin. With 35% capacity utilization and rising Zhangjiagang inventories, downstream demand remains weak. I expect limited price rebound u..
