On September 2, 2026, the comprehensive benchmark price for PX (via SunSirs) stood at 8,500 RMB/tonne, unchanged from the August 1 benchmark. Spot prices traded sideways between August and early September, remaining within a mid-range level for the year. Trading sentiment in the spot market was moderate, characterized primarily by small, on-demand orders rather than large-scale bulk purchasing; a clear tug-of-war between buyers and sellers persisted, preventing the formation of a distinct directional trend.
An analysis of PX customs data for July 2026 shows domestic imports at 513,000 tonnes—an increase month-on-month but a significant decline year-on-year. Imports had previously served to supplement domestic supply during a period of concentrated plant maintenance. Arrivals from Northeast Asia contracted as overseas plants restarted, altering the flow of supply within Asia. Cumulative imports for January–July fell year-on-year, while the share of domestic production rose, indicating continued improvement in self-sufficiency.
A review of domestic PX spot market dynamics since August reveals that production units in China and the broader Asian region completed maintenance and restarted, steadily raising overall operating rates and increasing the volume of tradable supply; the supply side thus saw a continuous ramp-up in output. Following an earlier period of inventory depletion, the market gradually shifted toward inventory accumulation as production recovered.
Significant negative feedback emerged from the downstream sector. PX is primarily consumed in PTA production; while downstream plants were also ramping up operations post-maintenance, the polyester industry faced profit pressure, and consumption of end-market textile fabrics showed no significant improvement. Faced with the dual pressures of volatile raw material prices and weak end-market demand, downstream players voluntarily reduced production and controlled operating rates. This trend transmitted directly upstream, curbing the pace of PX procurement. Even as downstream operating rates recovered, end-market consumption failed to keep pace; inventory pressure on finished goods cascaded upstream to raw materials, capping the upside potential for PX spot prices. Regarding costs, geopolitical tensions continue to cause fluctuations in crude oil prices; the resulting volatility in crude oil drives changes in feedstock costs, with PX spot prices tracking these movements—making crude oil a key external variable influencing spot prices. However, cost-driven factors are unlikely to alter the underlying supply-demand dynamics; constrained by negative feedback from downstream sectors, a rise in costs alone is unlikely to trigger a sustained increase in spot prices.
Looking ahead, domestic production rates may rise further, maintaining expectations of increased supply. On the downstream side, the focus remains on whether actual consumption in the polyester sector improves; if the market fails to recover, the negative feedback loop of downstream production cuts will persist. Overall, PX spot prices are expected to fluctuate within a neutral range in the short term. Key factors to monitor include operational changes at domestic and overseas plants, crude oil price volatility, the pace of imports, and the actual release of orders at the end of the polyester industry chain.
