Market Analysis

Updated:2026-09▲ Up this month
This Month's Trend

In September styrene was supported by crude and benzene costs, with East China prices running high at 9,950–10,250 RMB/t; H1 average was up about 11% YoY.

Key Drivers
  • Middle East tensions lifted crude and benzene, giving strong cost support to styrene
  • Downstream PS, ABS, SBR and unsaturated polyester entered the peak season, improving rigid demand
  • Industry operating rates and inventories drive short-term spot tightness
Outlook

Short term firm on cost support; medium term supply–demand博弈 intensifies — if downstream losses widen and new capacity is released, prices may ease. Watch crude, benzene and downstream runs.
