US Hexene Prices move 2.1% higher again in early June 2026

Hexene prices in the US moved into a firmer pattern in early June after a volatile May, with a mid-month slump and recovery. May began range-bound with normal operating rates, then mid-May pullbacks as converters slowed orders, followed by tighter prompt availability as downstream buyers and midstream players pre-booked loads ahead of early-summer demand, underpinning a rebound. Market sentiment shifted from discounting to selective restocking, setting the stage for modest gains in the opening week of June and tempering the sharp monthly decline seen in May. Demand dynamics for Hexene varied by end-use; weaker orders from LLDPE and HDPE pressured Hexene markets through mid-May, while stronger comonomer uptake supported late-May bids. Producers and distributors leaned into early-summer procurement, tightening prompt tonnage and lifting offers. On the month, FOB Texas declined about 9% as mid-month weakness and late-May recovery influenced pricing. The short-term outlook is stable to modestly bullish, aided by firmer comonomer demand, but feedstock volatility could quickly alter Hexene margins and repricing.
