The linked rise in crude oil and polyester feedstock prices injected a strong stimulus into the polyester filament yarn market on July 8, 2026. The average sales-to-production ratio of sample enterprises surged to 103.6%, a sharp increase of 60.7 percentage points from the previous trading day's closing data, meaning most enterprises achieved sales balance or even oversold. The speed of this data change is uncommon in the recent chemical fiber market.
Market Sentiment Reversal Behind the Data
Looking at specific sales data, the distribution of sales-to-production ratios among sample enterprises was extremely uneven: some reached 300%, while the lowest was only 10%, a span of 290 percentage points. This extreme divergence indicates that the price increase did not create a universal rally across the industry; instead, individual enterprises with channel or brand advantages benefited first. Overall, about 40% of the sample enterprises had ratios exceeding 100%, showing that market confidence is recovering from the bottom.
It is worth noting that the previous trading day's ratio was only 42.9%, in a relatively cold range for the industry. In just one day, market sentiment shifted from cautious waiting to active restocking, with the core catalyst being the synchronized rise in crude oil and polyester feedstock prices. The strengthening of Brent crude oil and PTA futures prices directly reduced the wait-and-see sentiment of downstream weaving enterprises, triggering a wave of concentrated procurement.
Cost Transmission and Supply-Demand Dynamics
As a midstream product in the chemical fiber industry chain, polyester filament yarn's price and sales ratio are directly influenced by upstream raw material costs such as crude oil, PTA, and MEG. The data from July 8 confirms the strong transmission effect of cost side on market sentiment: when raw material cost expectations rise, downstream weaving enterprises tend to lock in prices and increase stockpiles in advance to avoid higher future procurement costs.
However, this cost-driven procurement wave often has a 'front-running' nature. According to industry public data, social inventory of polyester filament yarn remains at a medium-to-high level, while actual demand in the terminal apparel and home textile markets has not shown a simultaneous increase. This means the current improvement in sales ratio is more about inventory transfer in the intermediate links, rather than a substantive recovery in end-user demand. Once feedstock prices correct, downstream enterprises' purchasing enthusiasm may quickly cool.
Industry Impact: Short-Term Positive, Long-Term Concerns
For polyester filament yarn producers, the recovery in sales ratio directly improves cash flow and inventory turnover speed. Some enterprises even oversold, allowing them to digest previously accumulated inventory pressure. This is positive for alleviating the overall loss situation in the industry—in the first half of 2026, most polyester factories were in a state of thin profit or even loss due to the dual pressure of overcapacity and weak demand.
However, from the perspective of industrial cluster reactions, the operating rates in major polyester clusters such as Xiaoshan and Shaoxing in Zhejiang have not significantly increased. This means enterprises are more focused on digesting existing inventory rather than starting new capacity. For downstream weaving enterprises, short-term price fluctuations increase the difficulty of procurement decisions: chasing price increases may face correction risks, while waiting may miss the low-price window.
