In a single trading day, the average sales-to-output ratio of polyester filament yarn sample enterprises surged from approximately 42.9% to 103.6%, a jump of 60.7 percentage points. On July 8, 2026, the chemical fiber market announced the short-term power of crude oil cost transmission with a set of contrasting data. But whether this wave can last is far from optimistic.
Cost Pulse and Production-Sales Divergence
According to closing data on July 8, the sample enterprises' sales-to-output ratio stood at 103.6%, up 60.7 percentage points from the previous trading day. Rising crude oil and polyester raw material prices directly boosted downstream purchasing sentiment. However, a closer look at individual data reveals wide disparities: the highest reached 300%, while the lowest was only 10%. This suggests that about half of the enterprises remain in a low sales state—the market is not universally recovering.
Based on industry public data, the previous trading day (July 7) saw a ratio of around 42.9%, near a yearly low. The July 8 spike was essentially a stress reaction from downstream buyers worried about further cost increases, prompting concentrated restocking rather than a surge in terminal orders. Such panic buying has occurred frequently in the chemical fiber industry, typically lasting only 3-5 trading days before fading.
Upstream Transmission and Downstream Bargaining
Higher crude oil prices transmit through intermediates like PX, PTA, and MEG to polyester filament yarn, putting pressure on costs. But downstream weaving mills face weak demand for finished garments. National Bureau of Statistics data shows that the textile industry's industrial value-added growth was only 2.1% in the first half of 2026, significantly lower than the same period last year. Weak consumer demand makes it difficult for weavers to pass on cost increases to their customers.
This puts polyester filament yarn producers in a dilemma: raising prices squeezes profit margins; lowering them may further dampen downstream buying. On July 8, the ratio climbed to 103.6%, and some producers tested price increases. But whether these stick depends on sales continuity over the next week. If restocking subsides, filament yarn inventories could rebuild.
Impact on Industrial Clusters and Foreign Trade
Geographically, polyester filament yarn capacity is concentrated in Zhejiang and Jiangsu provinces, with key clusters in Shengze, Changxing, and Xiaoshan. The sharp fluctuation on July 8 puts short-term pressure on local polyester plants' cash flow and inventory management. Smaller enterprises with low ratios (e.g., 10%-40%) face working capital difficulties.
On the foreign trade front, exports of polyester filament yarn and downstream fabrics are constrained by weak global textile demand. From January to May 2026, China's textile and apparel exports fell about 5% year-on-year, with chemical fiber filament fabric exports declining even more. Higher costs could further erode Chinese products' price competitiveness, especially as alternative suppliers in Southeast Asia and South Asia gain ground.
