The polyester filament market is undergoing a silent tug-of-war. On August 28, industry public data showed the average sales-to-production ratio of sample enterprises was only 34.7%, up 5.3 percentage points from the previous trading day. But this rebound did not come with active trading; downstream users' resistance to high prices has not faded, and inquiries remain sluggish. The market is in a typical 'high cost, low demand' stalemate.
Signals Behind the Data
The sales-to-production ratio is a core indicator of the match between polyester plants' willingness to ship and downstream willingness to accept. A 34.7% average means only about 35 tons out of every 100 tons produced are absorbed by the market that day. The breakdown shows more than half of sample enterprises had ratios between 20% and 30%, some even zero, while one reached 500%. This extreme divergence indicates structural differentiation: some differentiated products still have order support, while conventional specifications are sluggish.
Low ratios directly lead to passive inventory accumulation at polyester plants. When inventory pressure transmits to cash flow, plants face a dilemma: cut prices to move volume, sacrificing profit, or hold prices, betting on rigid demand release. Current market behavior shows most plants choose the latter, intensifying upstream-downstream game-playing. For weaving mills, high raw material prices coupled with flat terminal orders make procurement decisions extremely cautious, with just-in-time replenishment becoming mainstream.
Why the Stalemate Persists
The stalemate is not accidental. On the cost side, upstream PTA and MEG prices remain high, supported by crude oil volatility and supply contraction expectations, compressing polyester plants' room for concessions. On the demand side, terminal apparel and home textile orders are in the traditional seasonal transition, domestic recovery is weaker than expected, and export orders are stable but lack growth due to exchange rate and shipping cost disturbances. With weak supply and demand, polyester filament prices are trapped in narrow fluctuations.
The slight rebound in the ratio (+5.3 percentage points) may hint that some downstream buyers are starting to accept current price levels and testing replenishment. But one day's data is insufficient to confirm a trend; observation over 3-5 trading days is needed. If the ratio stays below 40%, inventory pressure will force strategy adjustments, and prices may loosen; conversely, if it rises above 50%, rigid demand release will strengthen price support.
Impact on the Chain
For polyester plants, low ratios mean increased capital occupation and short-term cash flow risk. Some small and medium plants may be forced to cut production or take maintenance to relieve inventory pressure, marginally affecting regional supply patterns. For weaving mills, the procurement window is lengthening; a 'small batches, multiple times' strategy is recommended to avoid buying at peaks. For foreign trade companies, exchange rate fluctuations and narrowing price negotiation space require flexibility in quotations.
From a regional perspective, weaving operating rates in major polyester filament production and sales areas like Shengze and Changxing remain stable, but new orders are insufficient and grey fabric inventories are rising. In Keqiao fabric market, recent inquiries focus on autumn/winter fabrics, with demand mainly for FDY and DTY, while POY moves slowly. These micro-signals indicate terminal demand has not yet formed a strong pull, and the chain is still waiting for a directional breakthrough.
