Polyester staple fiber (PSF) prices have experienced sharp fluctuations over the past year, swinging from a high of 8,426 yuan/ton to a low of 6,267 yuan/ton. The latest quote of 7,267 yuan/ton, while at a median level, represents a 2% decline from the beginning of the year. This data is not an isolated event but a result of the combined effects of capacity cycles in the chemical fiber sector and weak end-consumer demand. For the textile supply chain, these price signals demand a comprehensive reassessment of procurement strategies, inventory management, and risk hedging.
Structural Drivers of Price Volatility
Annual statistics show a price range of 25%, with a peak-to-trough difference of 1,158 yuan/ton and a trough-to-peak difference of 1,000 yuan/ton. Such amplitude is rare in the past three years, directly attributable to the mismatch between concentrated capacity releases in upstream PTA and slowing growth in downstream textile and apparel orders. Since the second half of 2025, several large domestic chemical fiber companies have brought new production lines online, increasing polyester supply by over 5%, while end demand, affected by global consumption downgrades, grew only about 2%. This supply-demand gap has gradually pulled the price center from above 8,000 yuan/ton to around 7,000 yuan/ton.
Notably, the current price of 7,267 yuan/ton is below the yearly median of 7,346 yuan/ton, indicating that the market remains in a weak range. The daily increase of only 0.06% reflects a lack of short-term directional momentum, with both buyers and sellers adopting a wait-and-see approach. For spinning mills and weaving enterprises, this means increased bargaining power in raw material procurement but also the risk of inventory depreciation if prices fall further.
Transmission and Differentiation in Industrial Clusters
The impact of price fluctuations varies significantly across different links of the chain. In weaving clusters such as Shengze and Changxing, small and medium-sized enterprises have reduced their raw material inventory cycles from the typical 15 days to 7-10 days to avoid losses from price declines. Traders in Keqiao are more inclined to adopt a "buy-as-needed" spot model, reducing long-term contract commitments. While this short-sighted behavior lowers capital occupation in the short term, it also weakens supply chain stability.
From a category perspective, the weakening of PSF prices has reduced cost support for downstream products such as polyester-cotton blended yarn and pure polyester yarn, with some yarn varieties already following the decline. However, the home textile sector, due to its relatively rigid demand, shows a lag in price transmission. Overall, the weak pattern of chemical fiber raw materials is penetrating into the terminal fabric segment, intensifying price competition for export orders.
Key Variables for Future Trends
Whether prices can stabilize depends on three factors: first, whether maintenance plans in the upstream PX-PTA segment can temporarily tighten supply; second, the realization of orders during the traditional peak season of "Golden September and Silver October"; and third, the impact of international oil price fluctuations on polyester costs. The current median of 7,346 yuan/ton can be seen as a bull-bear watershed. If peak season demand falls short of expectations, prices may once again test levels below 7,000 yuan/ton.
