On July 9, the polyester filament yarn market saw a sharp cooldown, with the average sales rate among sample enterprises falling to 40.4%, a cliff-like drop of 63.2 percentage points from the previous trading day. This data point is not an isolated price fluctuation but rather reveals the typical rhythm of downstream weaving mills after a concentrated restocking: a rapid shift to rational wait-and-see. Once the restocking impulse fades, the true demand picture becomes clear.
The Restocking Tide Recedes, Wait-and-See Sentiment Dominates
The concentrated restocking on the previous day (July 8) clearly exhausted most of the short-term procurement demand. Looking at the sales data from 24 sample companies on July 9, the distribution was extremely uneven: the highest was 180%, the lowest only 10%, and more than half of the companies had sales rates below 40%. This 'ice and fire' pattern indicates that the market is not in a broad recovery; rather, a few companies captured the restocking window through specific product varieties or pricing strategies.
Concentrated restocking essentially means downstream players have confirmed a temporary price floor for raw materials. When polyester filament prices fall to a psychological level for some weaving mills, it triggers a round of concentrated purchases. But after restocking is complete, inventory is replenished, and subsequent purchasing power naturally wanes. The July 9 data perfectly illustrates this logic: most users retreated to the sidelines, with only a few continuing to replenish.
Industrial Signals from Sales Rate Volatility
A 40.4% sales rate means only 40% of the day's output was absorbed by the market, with the remaining 60% adding to company inventories. For polyester filament producers, this undoubtedly increases inventory pressure. Accumulating inventories often, in turn, suppress ex-factory prices, creating a negative feedback loop: falling sales rate → rising inventory → price pressure → downstream waits for even lower prices.
It's worth noting that such drastic sales rate fluctuations are not new. Since June, the chemical fiber market has experienced several similar pulses of restocking followed by rapid cooling. This suggests that actual operating rates in the downstream weaving sector have not improved significantly, and terminal order sustainability is weak. Buyers prefer a 'small batch, high frequency' purchasing strategy over bulk stockpiling. This cautious mindset is essentially a defensive reaction to uncertainty about future demand.
The Game of Price Expectations and Divergence
Behind the sales rate data lies an intense game of price expectations between upstream and downstream. Weaving mills generally believe that current polyester filament prices are still in a bottoming phase, lacking sustained upward momentum. Therefore, their restocking often carries a 'bottom-fishing' mentality; once completed, they quickly shift to wait-and-see, anticipating the next price dip.
Upstream polyester plants face a dilemma: if they cut prices in response to falling sales rates, they may reinforce downstream wait-and-see expectations; if they hold prices firm, inventory pressure will continue to mount. Judging by the July 9 data, most plants passively accepted the sales rate decline without large-scale price cuts. This stalemate is likely to persist in the absence of new catalysts from the cost or demand side.
