US Gulf ethylene oxide (EO) prices declined 2.2% in the last week of August 2025, driven by a 5.8% drop in feedstock ethylene costs amid lower upstream energy prices. Despite the bearish momentum, stable demand from downstream sectors such as cleaning and ethylene glycols helped buffer the decline, keeping the market balanced. Overseas buyers should monitor feedstock trends and seasonal demand shifts for pricing signals in September.
Price and feedstock dynamics
Ethylene oxide prices fell 2.2% by the end of August, with the 6-week moving average settling at USD 931.16/MT, reflecting an extended bearish trend. Feedstock ethylene dropped 5.8%, easing input cost pressure for manufacturers. The decline was primarily linked to lower crude oil values upstream, which reduced production costs and supported competitive FOB prices for US exporters.
Downstream demand snapshot
Demand for EO derivatives remained mostly stagnant in August. Monoethylene glycol (MEG) consumption held steady, supported by PET packaging and antifreeze applications. Diethylene glycol (DEG) saw steady offtake from resin and ink end-users despite limited market activity. PTMEG demand from elastic fibre producers was flat. Glycol ethers, particularly ethylene glycol monobutyl ether (EGBE), experienced a slight seasonal uptick from coatings and cleaning sectors, along with industrial restocking.
Supply-side stability
EO production across US facilities remained stable in August. Producers calibrated output to match domestic demand while benefiting from lower feedstock costs. Inventory levels were well managed, ensuring consistent availability for critical derivative sectors. No major production interruptions were reported, and supply-side fundamentals remained firm, supporting a balanced market through the month.
What buyers should watch
Overseas buyers should track feedstock ethylene and crude oil trends, as further cost declines could extend EO price softening. Seasonal demand from packaging and automotive antifreeze sectors may support consumption mid-year, but a post-peak slowdown is anticipated. The current market reflects a cost-led correction rather than structural weakness, so price stability is expected in September if feedstock costs remain low.
