On September 1, trading activity in the polyester filament market cooled sharply, with the average sales-to-output ratio among sample enterprises dropping to 39.8%, a steep decline of 43.0 percentage points from the previous trading day's close. This figure reflects a typical pattern where late-day sales surges on August 31, with some producers reporting ratios as high as 300%-400%, pulled demand forward and triggered a wait-and-see mood when prices were raised the next day. The tug-of-war between price hikes and buyer resistance is likely to shape near-term price trends.
Market Context
The sales-to-output ratio is a key indicator of daily sales activity in the polyester filament market. On August 31, some producers boosted sales through promotions or discounts, with ratios reaching 300%-400%, significantly exhausting short-term demand. Consequently, on September 1, most specifications saw tentative price increases, but downstream buyers showed strong resistance, inquiries cooled, and the ratio fell below 40%.
Data from sample enterprises show a skewed distribution: the lowest ratio was 10%, the highest 150%, and most firms fell between 15% and 40%. Specific figures include 80%, 20%, 35%, 20%, 15%, 20%, 30%, 25%, 10%, 15%, 30%, 20%, 20%, 35%, 30%, 20%, 20%, 40%, 60%, 40%, 30%, 100%, 80%, and 150%. This divergence indicates not an overall demand collapse but a structural adjustment, with some specifications or companies still enjoying firm support.
Notably, the plunge in the ratio does not mean demand has vanished; it is a natural correction after the previous surge, compounded by wait-and-see sentiment due to price hike expectations. For buyers, this implies limited upside for prices in the short term, but raw material cost pressures persist, so they should watch for potential price support or production cuts by manufacturers.
Industry Impact
The volatile ratio directly affects price transmission along the supply chain. Upstream raw materials like PTA and MEG remain at high levels, squeezing polyester producers' margins, making price hikes a necessary move to pass on costs. However, downstream weaving and texturizing enterprises face insufficient orders and high finished-goods inventories, leaving them with low tolerance for raw material price increases. Their resistance is a rational response.
This upstream-downstream standoff is likely to lead to a price stalemate. For polyester plants, a ratio persistently below 40% means inventories will rebuild. If no improvement occurs within a week, some producers may resort to production cuts or maintenance to balance supply and demand. Historical patterns suggest that when the ratio stays below 50% for consecutive days, polyester filament prices often face downward pressure. If current price hike attempts fail to gain downstream acceptance, a price correction becomes more probable.
For weaving mills, cautious inventory replenishment is advisable at this juncture. On one hand, mills with low raw material stocks might wait for price pullbacks before purchasing; on the other hand, if upstream production cuts materialize, prices could stabilize and rebound, so excessive waiting carries the risk of missing the bottom. It is recommended that companies adopt a batch purchasing strategy based on their order cycles and cash flow, avoiding concentrated single-day replenishment.
Practical Recommendations
For Buyers - Adopt a wait-and-see approach in the short term, monitoring the ratio's trend; if it stays below 40% for more than three days, consider building positions in batches after price corrections. - Sign monthly framework agreements with suppliers to lock in part of the volume and reduce spot market volatility risk.
For Polyester Producers - Avoid unilateral price increases; consider offering discounts or extended payment terms to ease downstream resistance. - If the ratio remains low, plan production cuts or maintenance in advance to prevent excessive inventory buildup.
In summary, the polyester filament market is likely to experience high-frequency fluctuations in September, with sales-output data serving as a key indicator for identifying turning points. All parties along the supply chain should closely monitor daily ratio and inventory changes and adjust operational strategies flexibly.
