On July 24, the spot price of polyester staple fiber in Jiangsu surged by 40 yuan per ton to 7,670 yuan/ton, with the negotiation range simultaneously moving up to 7,620-7,750 yuan/ton, and low-end deals rising from around 7,500 yuan/ton. This price jump stands out amid recent polyester chain volatility, reflecting an ongoing tug-of-war between upstream cost support and downstream demand weakness.
Cost Side: Crude Oil Weakness Fails to Curb Polyester Feedstock Gains
Early Asian session crude oil prices fell, which theoretically should have weakened cost support for the polyester chain. However, actual market performance showed that polyester feedstock and staple fiber futures only slightly pared gains, while spot prices rose against the trend. This indicates that current staple fiber pricing has partially decoupled from pure crude oil cost anchoring, now more constrained by tight spot supply of intermediate raw materials like PTA and MEG. Jiangsu, as a major polyester staple fiber producing region, directly reflects upstream polyester feedstock supply-demand contradictions—PTA unit maintenance combined with import contraction force polyester plants to pass costs downstream via price hikes.
Regional Industrial Belt: Jiangsu Quotation Becomes Industry Benchmark
Jiangsu accounts for nearly 30% of China's polyester staple fiber capacity. Its daily spot quotations not only serve as local transaction benchmarks but also rapidly transmit to downstream weaving clusters in Zhejiang and Fujian. The current negotiation range of 7,620-7,750 yuan/ton means that yarn manufacturers' procurement costs have increased by approximately 0.5% compared to last week. For pure polyester yarn and polyester-cotton yarn producers operating on razor-thin margins, this increase may trigger passive price adjustments. Notably, low-end supply at around 7,500 yuan/ton still circulates, indicating that the market is not uniformly bullish—some holders still face destocking pressure, and price divergence is unlikely to resolve soon.
Supply-Demand Dynamics: Short-Term Support vs. Medium-Term Risks
On the supply side, some Jiangsu staple fiber units maintain around 80% operating rates, with no large-scale production cuts. However, polyester plants generally hold low feedstock inventories, and replenishment demand provides bottom support for staple fiber prices. On the demand side, the market exhibits "rigid demand underpinning, speculative demand absent" characteristics: downstream weaving enterprises purchase on a need basis, avoiding stockpiling, resulting in small-to-medium-sized spot transactions. This structure means that if crude oil or polyester feedstock experiences a trend decline, the correction space for staple fiber prices could expand rapidly.
