US acetone prices are expected to trend lower through June 2026, with market sentiment turning increasingly bearish as ample domestic supply meets weakening downstream demand. High operating rates at integrated phenol–acetone units and the absence of major outages ensure that June supply remains abundant, keeping sellers competitive and widening discounts. Downstream sectors, including construction materials, automotive coatings, adhesives, and Bisphenol-A derivatives, are entering their seasonal off-peak period, reinforcing cautious, just-in-time procurement and limiting any upward price momentum. Softer crude oil, benzene, and propylene projections further weaken cost-side support, allowing producers to reduce offers without margin strain. This June outlook contrasts sharply with May, when U.S. acetone prices moved higher on tightening merchant availability, early-month process upsets, and rising feedstock costs. Weekly dynamics showed a tightening pattern, with prices climbing through mid-May and spiking in the week ending May 24 before easing into a moderate rise. The final week’s 1.55% increase reflected low prompt inventories and buyers accepting higher offers to secure immediate tonnes.
