Buyer confidence in Southeast Asia wanes further as price signals lose direction
Regional polyolefin markets are sliding further out of sync, as a supply-led PE surge clashes with volatility-driven paralysis in PP, eroding price discovery across Southeast Asia. Vietnam’s PE market has reset sharply higher on Middle East risks and tightening supply, while Chinese PP exports are being whipsawed by erratic oil swings, leaving offers misaligned with weak demand and draining liquidity.
Directional conviction is fading as uncertainty around the Strait of Hormuz continues to trigger sharp but unsustained repricing. Buyers remain sidelined, and without clearer geopolitical cues, elevated prices risk staying largely notional, with fragmented sentiment capping any recovery in trade.
