On July 22, spot prices of polyester staple fiber (PSF) in Jiangsu posted a notable increase of 60 yuan/ton, with the mainstream trading range climbing to 7,520-7,600 yuan/ton, while some lower-priced supplies remained around 7,450 yuan/ton. This rise stands out against the recent calm in the chemical fiber market, but the driving force is not a recovery in end-user orders but a cost-side push from geopolitical tensions.
Background
The immediate trigger for this PSF price hike is the repeated geopolitical conflicts that have heightened volatility in international crude oil prices, thereby raising the costs of polyester raw materials such as PTA and MEG. Jiangsu, as a major production base for PSF in China, serves as a bellwether for the national market. The data shows that this rally is a passive adjustment rather than an active markup, highlighting the sensitive and rapid transmission of upstream costs downstream.
Notably, although the overall PSF price has moved up, there is a clear divergence within the market: the high-end quote has reached 7,600 yuan/ton, while some low-priced supplies are only at 7,450 yuan/ton, a spread of 150 yuan/ton. This divergence indicates differences in inventory levels and cost structures among enterprises, and also suggests that the market has not yet formed a consensus on the future direction.
Industry Impact
For weaving mills, the rise in PSF costs will directly compress the profit margins of grey fabrics. Currently, the downstream fabric market has not seen a significant increase in orders, and end-brand apparel procurement remains cautious, meaning that mills cannot fully pass on the raw material price increase to customers. Some small and medium-sized weaving mills may be forced to reduce operating rates or switch to alternative raw materials, such as recycled PSF or cotton-type viscose staple fiber.
From the perspective of traders, this price increase may trigger a round of short-term restocking. Some intermediaries with low inventory levels may choose to chase the rally, but they need to be wary of the risk of a price pullback. Given the high uncertainty in the geopolitical situation, PSF prices may exhibit a pattern of 'fast rise, slow fall' or 'high-level oscillation' in the short term.
For upstream polyester plants, cost-push price increases can temporarily improve processing margins, but if downstream demand remains weak, the rally will be unsustainable. Industry public data shows that the operating rate of the PSF industry has remained relatively high this year, but social inventories are also slowly accumulating, making the supply-demand balance fragile.
