The US ethylene oxide prices remained under pressure through mid-June 2026 as declining feedstock costs and comfortable inventories outweighed support from downstream MEG and PET packaging demand. While May established a stronger pricing environment, market attention shifted toward June as falling ethylene values reduced production costs and encouraged a softer pricing approach. Ethylene oxide demand from monoethylene glycol producers and packaging applications remained relatively healthy, helping prevent a steeper correction, but weaker export inquiries and cautious industrial procurement limited upside opportunities. Stable operating rates across Gulf Coast facilities ensured adequate product availability, while logistics conditions remained smooth. Comfortable inventory levels and reduced feedstock costs continued to weigh on sentiment, encouraging sellers to prioritize volume retention over aggressive pricing. Although downstream consumption remains supportive, current market fundamentals point to a softer near-term outlook. Ethylene oxide prices are expected to remain under pressure through the remainder of June unless export demand strengthens or unexpected supply disruptions emerge.
