On September 2, 2026, the polyester filament market revealed a striking divergence: the average sales-to-output ratio among sample enterprises stood at only 39.1%, down 0.7 percentage points from the previous trading day, yet individual figures ranged wildly from a high of 310% to repeated zeros. This ice-and-fire pattern is not merely a sign of weak demand; it reflects a standoff in price negotiations between upstream and downstream players, and signals subtle shifts in the industry's pricing mechanism.
Signals Behind the Data
The daily sales-to-output ratios spanned from 0% to 310%, with the 310% outlier indicating that one enterprise sold the equivalent of three days' production in a single day. In stark contrast, several enterprises recorded zero sales, underscoring overall sluggish trading. This coexistence of extremes suggests that demand has not vanished but is highly concentrated among a few suppliers with price advantages or strong customer loyalty. Although most producers raised their quotations, the actual transaction prices varied significantly, implying that price hikes lacked broad support and were more of a cost-push reaction.
From an industry perspective, the average ratio of 39.1% has remained below the boom-bust line for several consecutive days, signaling that downstream weaving mills are reluctant to build inventories. The expectation of price increases failed to spur restocking; instead, it reinforced a wait-and-see attitude, typical of a market where prices are quoted but few deals are concluded. Notably, only "partial users made small replenishments," suggesting that essential demand reluctantly accepted higher prices, while most buyers chose to stay on the sidelines, anticipating further price declines.
Value Chain Transmission and Pricing Logic Evolution
As a core intermediate in the polyester chain, polyester filament prices are directly influenced by upstream PTA and MEG costs, while simultaneously transmitting pressures to downstream weaving and apparel sectors. The core of the current upstream-downstream tussle lies in a mismatch: high upstream raw material costs squeeze filament producers' margins, compelling them to raise prices to protect profits; however, downstream weaving mills, facing weak end-demand and their own inventory pressures, are highly sensitive to raw material price increases and adopt conservative purchasing strategies. This misalignment has led to a breakdown in the price transmission mechanism—upstream price hikes fail to pass through effectively, instead suppressing transaction volumes.
More notably, the extreme divergence in sales-to-output ratios may signal a transition in pricing models from "factory-listed prices" to "actual transaction prices." The 310% ratio might not reflect genuine demand surge but could be the result of a single large producer offering discounts or credit terms to attract concentrated orders. If such cases become frequent, they will undermine the credibility of overall quotations. For buyers, this means they should not rely solely on published prices; they must verify actual transaction ranges. For producers, it necessitates a reassessment of the sustainability of price hike strategies, avoiding further order losses by clinging to high prices.
Short-Term Outlook and Operational Strategies
Looking ahead, polyester filament prices are likely to remain volatile within a range. If upstream costs do not drop substantially, producers' intention to hold prices firm will persist, but downstream acceptance remains limited, potentially leading to a prolonged stalemate of low sales ratios and high wait-and-see sentiment. Should a leading enterprise initiate price cuts to stimulate sales, a chain reaction could accelerate the downward movement of the price center. Conversely, a seasonal recovery in end-demand (e.g., pre-holiday stockpiling before the National Day holiday) could trigger a round of restocking. However, based on current data, the supply-demand contradiction has not eased, and reversal signals are not yet clear.
