7,500 yuan per ton—this is the key price level that the Jiangsu polyester staple fiber spot market has recently broken through. Under the dual influence of cost side and geopolitics, staple fiber prices are undergoing a new round of adjustment.
Cost Pass-Through and Market Response
The spot price of polyester staple fiber in Jiangsu has risen to 7,530 yuan/ton, up 30 yuan from the previous trading day. The actual negotiation range is concentrated at 7,450-7,650 yuan/ton, with sporadic transactions near 7,400 yuan/ton for lower-grade goods. This price level means that staple fiber has re-crossed the industry's psychological threshold, directly impacting the procurement decisions of downstream weaving mills.
The direct driver of this price increase comes from the upstream: international oil prices have continued to rise due to geopolitical conflicts. As the source of the polyester industrial chain, oil price fluctuations are transmitted step by step to polyester staple fiber through intermediate links such as PX and PTA. The cost support has significantly strengthened, forcing staple fiber producers to follow the uptrend to maintain processing profits.
From an industrial perspective, the linkage between staple fiber prices and crude oil has been particularly tight since 2025. When oil prices break through key resistance levels, various links in the polyester chain often react within 24-48 hours. The Jiangsu market's price adjustment within 8 hours reflects the market's increasing sensitivity to cost-side changes.
Impact on Upstream and Downstream of the Chain
For staple fiber producers, the price increase means a temporary restoration of profit margins. Previously, due to frequent raw material price fluctuations, staple fiber mills mostly adopted low-inventory strategies. This price hike helps alleviate cost pressures. However, it should be noted that if oil prices fall rapidly, staple fiber prices may also pull back, exposing companies to inventory depreciation risks.
Downstream weaving and texturing enterprises face a dilemma: on one hand, current order volumes have not shown significant growth, and end-user demand remains weak; on the other hand, rising raw material prices directly compress factory processing profits. Some small and medium-sized weaving mills may choose to slow down procurement, waiting for price corrections, but this risks production interruptions due to insufficient inventory.
From a regional perspective, Jiangsu, as a major production and sales area for polyester staple fiber, has a bellwether effect on the national market. Procurement managers in textile clusters such as Shengze and Nantong are reassessing raw material costs, with some companies starting small-scale replenishment to hedge against potential further price increases.
Outlook and Operational Strategies
In the short term, geopolitical factors remain the biggest variable for oil price trends. If the conflict escalates, crude oil prices may rise further, providing sustained support for staple fiber prices. However, if the situation eases, oil price corrections will quickly transmit to the polyester chain, and staple fiber prices face downside risks.
From a medium-term perspective, the supply-demand fundamentals of polyester staple fiber have not fundamentally changed. Industry capacity remains relatively oversupplied, and downstream demand recovery is slow. This price increase is more cost-driven than demand-driven, so the sustainability and magnitude of the rise remain uncertain.
