7,500 yuan per ton — that was the spot price for polyester staple fiber (PSF) in Jiangsu on July 14, up 110 yuan from the previous day. A single-day increase of over 1.4% is unusual in the relatively stable chemical fiber market of late.
Background
The price surge is driven by upstream costs. Heightened geopolitical risks have pushed international crude oil prices higher, dragging up polyester feedstocks like PX, PTA, and MEG. As a direct downstream product of the polyester chain, PSF production costs rose sharply, forcing mills to raise offers to pass on the burden.
In the spot market, the trading range in Jiangsu narrowed to 7,450-7,600 yuan/ton, with lower-end goods around 7,350 yuan/ton. The spread between high and low quotes shrank from over 200 yuan to just 150 yuan, indicating stronger seller bargaining power and dwindling low-priced supply.
Industry Impact
The impact of this price hike varies along the chain. For PSF producers, cost-driven price increases can ease margin pressure, but if end-user demand fails to keep pace, inventory pressure may build. Downstream yarn mills are operating at moderate capacity and show limited appetite for high-priced feedstock.
- Buyers: Weaving and yarn mills are adopting a hand-to-mouth purchasing strategy, with little stockpiling appetite. Smaller factories may delay replenishment and shift to a wait-and-see stance.
- Traders: Intermediaries are more willing to sell into strength, but cautious end-users keep actual transaction volumes from expanding significantly.
- Exporters: Combined with RMB exchange rate fluctuations, the domestic price rise may erode the price competitiveness of Chinese PSF in Southeast Asian markets in the short term.
From a broader perspective, this price spike once again exposes the fragility of the polyester supply chain — upstream feedstock is heavily dependent on crude oil, which is highly susceptible to geopolitical disruptions. For China's chemical fiber industry, which has long relied on cost advantages, establishing a more stable feedstock supply and pricing mechanism remains an ongoing challenge.
