What is driving the recent price volatility of diethylene glycol monobutyl ether in China?
DGBE prices in China have shown sharp swings recently. In early July, East China spot prices fell 4.6% week-on-week to around 13,550 yuan/ton, pressured by weak buying interest and falling upstream n-butanol costs. However, during Q1 2026, DGBE surged over 50% amid a broader coatings raw material rally, driven by rising crude oil, tight supply from plant turnarounds, and robust downstream demand recovery. By June 2026, prices crashed over 22% month-on-month as export orders for coatings and inks collapsed following US tariff hikes, hitting solvent demand hardest. This volatility underscores DGBE's sensitivity to both feedstock costs (ethylene oxide, n-butanol) and downstream manufacturing activity, particularly in export-oriented sectors.
