PC: After lying in wait, now poised to strike!
After a weak consolidation and brief period of stagnation in July, the PC market experienced a phased rebound in August, with spot prices rising steadily and factory ex-factory prices gradually increasing. The industry has fully moved past the sluggish and volatile conditions of July, forming a multi-factor upward trend driven by cost support, tight supply, recovering demand, and bullish market sentiment.
Raw material costs rebound, strengthening the price floor.

The core raw materials for PC—bisphenol A, pure benzene, acetone, and phenol—remained firm and generally trending upward in August. Combined with relatively strong international crude oil prices and fluctuating operating loads at some overseas petrochemical plants, supply from upstream basic materials tightened, driving continuous price increases. In contrast to July, when weak raw material prices dragged down the market, August saw a complete reversal of this downward trend, providing solid bottom support for the PC market. As upstream costs steadily rose, they effectively compressed production margins for PC manufacturers, prompting factories to collectively adjust prices to pass on higher costs, thus laying a solid foundation for finished product price increases. The price transmission along the industrial chain remained smooth and efficient.
Supply contraction and improved supply-demand dynamics
Since August, several major domestic PC production facilities have continued operating at reduced capacity or undergoing maintenance, keeping the overall industry utilization rate at a relatively low to moderate level. Leading companies such as Wanhua Chemical and Hengli Petrochemical have implemented supply controls based on demand, moderately restricting output and directly tightening the domestic supply flow. Meanwhile, the PC industry is currently in a period of no new capacity additions, allowing the earlier surge in supply to be fully absorbed, marking a definitive departure from the oversupplied, loose market conditions seen in July. On the import front, fluctuations in overseas plant operations and international logistics have led to a month-on-month decline in imported arrivals in August, further helping to fill the domestic supply gap. The combination of short-term supply contraction and low inventory levels has shifted the PC market in August from a state of loose supply-demand balance to a tight equilibrium, creating the core conditions for sustained price increases.

Downstream demand is recovering, and the capacity to support essential needs has strengthened.
Under the traditional "golden September, silver October" peak season expectations, downstream industries such as automotive, electronics, and photovoltaic building materials have begun replenishing inventory in advance. Demand in the automotive lightweighting sector remains steadily released, with orders for PC components used in new energy vehicle exteriors, headlights, and charging stations increasing steadily. The electronics and home appliances sectors are concluding their off-season period, seeing a recovery in orders that has boosted procurement of general-purpose PC materials. Additionally, demand in August remained stable in areas such as photovoltaic daylighting panels and outdoor construction materials, prompting end-user companies to capitalize on the low-price window from July to August by concentrating on inventory restocking, significantly enhancing market demand resilience.

Market sentiment is improving, and industry confidence is recovering.
As fundamentals continued to improve in August, market pessimism completely dissipated. Traders, having depleted their low-level inventories, showed strong reluctance to sell and a firm intent to support prices. End users anticipated sustained price increases, leading to more forward booking and early stockpiling, which further boosted trading activity and amplified both the magnitude of price hikes and the durability of the upward trend.
In summary, this round of price increases represents a return to value following short-term industry adjustments. Inventory reduction in July and capacity clearance laid the foundation for market recovery, while favorable factors—including costs, supply, demand, and sentiment—converged in August, driving the sector's gradual rebound. In the short term, prices remain firm at higher levels; in the medium to long term, as peak-season demand materializes, industry sentiment will continue to improve, potentially ushering in a phase of steady, sustained upward momentum.
