On September 1, the polyester filament market showed sharp divergence: the average sales-to-output ratio among sampled enterprises stood at only 39.8%, a dramatic drop of 43 percentage points from the previous trading day's close, despite some manufacturers reporting ratios as high as 300%-400% at the prior close. This contrast signals not merely demand fluctuation but a typical stalemate in price negotiation. As upstream producers attempted to leverage price hikes, downstream users expressed clear resistance by 'voting with their feet,' causing market inquiry sentiment to cool.
Interpreting the Sales Data Anomaly
Sharp fluctuations in sales-to-output ratios are often simplistically attributed to demand changes, but September 1 data should be viewed as a market reaction to a 'price test.' The surge in sales at the previous close essentially reflected concentrated stockpiling by some buyers in anticipation of price increases, temporarily boosting ratios. However, when official price hikes for most specifications took effect the next day, real demand quickly revealed itself—an average ratio of 39.8% means over half of production capacity failed to convert into current sales, re-surfacing inventory pressure.
Notably, the dispersion among sampled enterprises was extremely high, ranging from 10% to 150%. This divergence indicates a non-monolithic market: a few companies maintain higher sales through product differentiation or customer loyalty, while most face order attrition. For buyers, this means that bargaining power varies significantly across suppliers at any given time, and price negotiation space is not uniform.
Short-Term Failure of Price Transmission
Price hikes in polyester filament should ideally transmit down the supply chain, but the resistance encountered indicates that current price levels are nearing downstream users' psychological thresholds. Weaving enterprises face difficulties in raising their own product prices and grapple with high grey fabric inventories, limiting their capacity to absorb raw material cost increases. When upstream price rises exceed what downstream can digest, the transmission chain breaks, manifesting as plummeting sales ratios and cooling inquiries.
This short-term failure does not signal a trend reversal. Historically, chemical fiber price fluctuations often exhibit a 'pulse-like' pattern: price hike attempts followed by shrinking volumes, then either price rollbacks or promotional inventory clearance. The key lies in observing whether sales ratios recover in the coming sessions—if they remain sluggish, prices likely face downward pressure; if they quickly rebound, demand resilience is evident, lending support to the hikes.
Chain-Wide Ripple Effects
The sales ratio data not only serves as a thermometer for daily trading activity but also directly impacts production scheduling and inventory strategies across the upstream and downstream. For polyester filament plants, a ratio below 40% implies rapid inventory accumulation and increased capital occupation, potentially forcing them to adopt price concessions, promotions, or output cuts. Conversely, for downstream weaving enterprises, high price volatility complicates procurement decisions—chasing hikes risks correction, while waiting may miss low-price restocking opportunities.
Moreover, this fluctuation conveys a macro-level signal: terminal demand has not shown strong recovery, and the textile industry chain remains in a weak equilibrium. In the absence of substantive demand pull, any cost-driven price increases are unlikely to sustain, and the market will more frequently experience 'hike—resistance—correction' cycles.
