Crude Oil Cost Pass-Through Accelerates: Jiangsu Polyester Staple Fiber Jumps 110 Yuan in a Single Day, Textile Raw Material Market Faces Another Stress Test

A rebound in crude oil prices is rapidly transmitting through the chemical fiber supply chain. On the morning of July 8, the spot price of polyester staple fiber in Jiangsu surged significantly, with a single-day increase of 110 yuan per ton, pushing the mainstream quotation to 7,300 yuan per ton. This is not merely a numerical change; it signals a new round of cost-driven price revaluation in the textile raw material sector.

The Cost Pass-Through Lag is Shortening

The transmission from international crude oil prices to polyester staple fiber spot prices used to take more than a week, but this time it has achieved near-simultaneous reaction. Data shows that the negotiation range for Jiangsu polyester staple fiber on that day was between 7,250 and 7,350 yuan per ton, with lower-priced sources also maintaining around 7,050 yuan per ton, indicating a clear upward shift in the overall price center.

Behind this rapid transmission lies the high integration of the polyester industry chain. Upstream PTA and ethylene glycol prices are highly sensitive to crude oil fluctuations, and as a direct downstream product, raw materials account for over 80% of polyester staple fiber production costs. Once oil prices rise, the cost pressure on polyester mills quickly spills downstream. For staple fiber producers, whether the 7,300 yuan per ton price can hold depends on subsequent crude oil trends and downstream order willingness.

Supply-Demand Game: Mismatch Between Cost Push and Demand Absorption

The current contradiction in the polyester staple fiber market is the mismatch between upstream cost-driven price increases and downstream demand absorption capacity. According to industry public data, operating rates at downstream yarn mills have remained at medium-to-low levels since June, with no significant pickup in terminal apparel export orders. This means the price increase is more cost-driven than demand-driven.

The direct consequence of this mismatch is that downstream buyers may adopt a wait-and-see approach, delaying restocking, which could lead to inventory accumulation at upstream polyester mills. Should crude oil prices retreat, the earlier inflated staple fiber prices could face a rapid correction. For traders and weaving mills, procurement decisions at this juncture require extra caution—balancing the risk of further raw material cost increases against the risk of price declines due to weak demand.

Cascading Effects on Regional Industrial Clusters

As one of China's major polyester staple fiber production bases, price movements in Jiangsu serve as a bellwether for the national market. Textile industry clusters in the Jiangsu-Zhejiang region, including Shengze, Nantong, and Shaoxing, are heavily reliant on polyester staple fiber. This price hike will directly raise raw material costs for local yarn mills, subsequently passing through to grey fabric and finished fabric sectors.

For Nantong's home textile cluster, where polyester staple fiber is a key raw material for fillings and some fabrics, rising costs could squeeze already thin profit margins. Weaving mills in Shengze may need to reassess raw material procurement budgets, with smaller enterprises potentially facing cash flow pressure. This regional cost shock will ultimately ripple through the supply chain to end-brand apparel and retail markets.

Practical Recommendations

For Buyers - Adopt a phased procurement strategy in the short term to avoid large one-time purchases at peak prices, reducing inventory risk. - Closely monitor international crude oil futures, especially short-term volatility ranges for WTI and Brent, as leading indicators for staple fiber price turning points. - Negotiate short-term floating price agreements with upstream suppliers to lock in some supply while retaining price adjustment flexibility.

For Foreign Trade Companies - Include raw material price fluctuation clauses in export quotations, clearly defining adjustment mechanisms for exchange rates and raw material costs to avoid order losses due to short-term price swings. - Evaluate the delivery cycle of existing orders; if delivery exceeds 30 days, consider locking in some raw material costs in advance to hedge against upward price risk. - Monitor price trends for similar products in Southeast Asian markets. If domestic staple fiber prices remain elevated, some low-value-added orders may face pressure to shift to countries like Vietnam and Bangladesh.
