On July 15, Jiangsu polyester staple fiber (PSF) spot prices rose by 30 yuan/ton, with the mainstream trading range settling at 7,450-7,650 yuan/ton and lower-end deals around 7,400 yuan/ton. This price adjustment is not an isolated event—it reflects the ongoing transmission of geopolitical tensions into crude oil costs, placing renewed cost pressure on the chemical fiber sector.
Direct Impact from the Cost Side
The primary driver of this PSF price increase is the raw material cost. Geopolitical conflicts have pushed up international oil prices, lifting upstream chemicals such as PX and PTA, which in turn raise PSF production costs. Typically, oil price fluctuations take 3-5 working days to fully transmit to PSF spot prices, but this adjustment occurred almost simultaneously with the oil rally, indicating heightened market sensitivity to cost changes.
Jiangsu, as a major PSF production base in China, often sets the price tone for the entire industry. The current quote of 7,530 yuan/ton, up 30 yuan from the previous day, may seem modest, but against a backdrop of generally weak demand, its psychological impact on downstream expectations far exceeds the numerical change.
Regional Price Spreads Reveal Supply-Demand Divergence
Regional price differences tell a more nuanced story. For 1.4D semi-dull direct-spun PSF, the negotiation range in Jiangsu-Zhejiang is 7,400-7,650 yuan/ton ex-works or short-delivery; in Fujian, it is 7,450-7,650 yuan/ton cash short-delivery; while in Shandong and Hebei, prices reach 7,550-7,750 yuan/ton delivered.
- Shandong and Hebei prices are 100-150 yuan/ton higher than Jiangsu-Zhejiang, suggesting tighter supply or higher logistics costs in the north.
- Fujian prices are roughly in line with Jiangsu-Zhejiang, indicating balanced supply-demand within East China.
- The existence of lower-end prices around 7,400 yuan/ton shows that some mills are still destocking or fulfilling earlier orders, and the market has yet to form a unified bullish expectation.
This regional divergence means that downstream buyers with cross-regional sourcing capability still have room to negotiate lower prices, while those dependent on single suppliers will inevitably face cost increases.
Short-Term Price Outlook
Based on current fundamentals, PSF prices are likely to maintain an upward bias over the next one to two weeks, though the pace of gains may slow. Supporting factors include: crude oil prices remain elevated due to geopolitical premiums; PTA and MEG inventories are at moderate-to-low levels; and PSF plant operating rates have not increased significantly despite the price rise, limiting supply elasticity.
On the other hand, headwinds exist: downstream weaving mill operating rates are around 60%, and final orders have yet to show a clear recovery; some traders have already built inventories and are less willing to stock up further; and a pullback in oil prices could quickly erase PSF gains.
Overall, this price increase is cost-push rather than demand-pull. For buyers, chasing the rally carries more risk than waiting for a pullback.
