China Phenol Chain Outlook 2026: Overcapacity Caps the Oil-Driven Rebound

Higher oil prices lifted China’s phenol chain again in July, but the response was far more restrained than in March because overcapacity and weak demand remain entrenched.

Key Takeaways

• Prices increased rapidly and then began to fall by mid-July.
• BPA prices rose less than upstream phenol and acetone, worsening producer losses.
• Most Chinese epichlorohydrin capacity uses glycerine rather than propylene, limiting the direct effect of oil-price changes.

Phenol and Acetone Quickly Lost Momentum

Prices increased rapidly and then began to fall by mid-July. Even with some plants under maintenance, supply did not tighten enough to sustain the rally because capacity remains ample and downstream demand has not improved.

Bisphenol A Producers Remain Under Pressure

BPA prices rose less than upstream phenol and acetone, worsening producer losses. Two new units commissioned in Q2 made increases more difficult, and BPA softened again as feedstock prices eased.

Epichlorohydrin Followed a Different Cost Path

Most Chinese epichlorohydrin capacity uses glycerine rather than propylene, limiting the direct effect of oil-price changes. Recent increases were driven more by glycerine costs. Glycerine-based producers remain close to loss-making economics.

Epoxy Resin and Polycarbonate Rallies Were Brief

Epoxy resin margins fell from high March levels toward breakeven or losses because of overcapacity, weak purchasing power and softer feedstocks. The latest rebound faded quickly. Polycarbonate producers benefited from maintenance in Q2, but prices and margins fell rapidly in June; lower prices later helped demand recover somewhat.

H2 Outlook

The market is behaving more rationally than it did in March. Unless downstream demand improves, oil-driven cost increases are unlikely to produce the same scale of price volatility.
