US Mixed Xylene Prices Fall 6.45% in late May 2026, as supply improves

The US mixed xylene market entered June 2026 with a firm undertone despite a late-May correction, as underlying supply and demand fundamentals continued supporting elevated pricing levels. Mixed xylene demand from gasoline blending and paraxylene production remained healthy throughout May, while domestic supply constraints and strong aromatics-chain economics sustained seller confidence. Although spot offers softened toward the month-end following improved logistics and short-term supply relief, the broader market remained considerably stronger than recent historical norms. Rising crude oil values, constrained reformate availability, and steady procurement from refiners and aromatics consumers continued to underpin market sentiment. Market participants remain focused on summer gasoline blending demand, refinery operating rates, and crude price movements as key indicators for the coming weeks. While periodic corrections remain possible, mixed xylene fundamentals continue to favor a constructive outlook, with supply limitations and resilient downstream demand expected to support pricing through the near term.
