Polyester staple fiber (PSF) prices have climbed to 7,816.55 RMB per ton as of September 1, 2026, up 3.32% from a month earlier and marking a daily gain of 0.93%. The price is now approaching the one-year high of 8,426.02 RMB, leaving only about 7.4% upside to the peak. For the textile supply chain, any significant movement in raw materials triggers cost pass-through and profit redistribution, and this uptick is no exception.
Market Context
Annual data shows that over the past 12 months, PSF prices ranged from a low of 6,267.17 to a high of 8,426.02 RMB, with an average of 7,126.48 RMB. The current price sits about 9.7% above that average, placing it in the mid-to-high range of the year and above the median of 7,346.6 RMB. This upward shift is not an isolated event; it results from rising upstream costs—such as crude oil and PTA—combined with downstream restocking demand.
The daily gain of 0.93% is a moderately strong move for PSF, indicating some market sentiment heating up. However, the gap to the yearly high is still 609.47 RMB, suggesting overhead resistance. Whether prices can break through the previous peak depends on the alignment of supply and demand. For buyers, the cost of chasing the rally versus waiting is rising.
Regionally, major PSF production and consumption areas like Jiangsu, Zhejiang, and Fujian have seen a noticeable increase in inquiries. Some traders are testing price hikes, but downstream weaving mills remain cautious, keeping raw material inventories at a 7-10 day safety level. This pattern of 'hot upstream, cold downstream' often signals that prices may face correction pressure after a sharp rise.
Industry Impact
The rise in PSF prices directly impacts the cost structure of downstream yarn and fabric manufacturers. For pure polyester yarn, raw material costs typically account for over 70% of total costs. A 100 RMB per ton increase in PSF raises yarn costs by approximately 150 RMB per ton. If end orders cannot be repriced accordingly, profit margins will be squeezed, especially for small and medium factories producing low value-added goods.
For exporters, the combination of raw material volatility and currency fluctuations complicates pricing. With PSF at mid-to-high levels, if prices continue to strengthen over the next three months, hedging and lock-in strategies need to be adjusted. Conversely, if prices fall, companies that stocked up at high levels face inventory devaluation risks.
From an inventory cycle perspective, the current price level corresponds to an active restocking phase. Industry data shows that over the past month, PSF mill inventories have declined by about 2 days, indicating smooth destocking. However, downstream weaving operating rates have not risen proportionally, suggesting that restocking is more speculative than demand-driven. Once speculative demand fades, price support may weaken.
