On August 28, trading activity in the polyester filament market remained subdued, with the average sales-to-output ratio of sample enterprises at 34.7%, up 5.3 percentage points from the previous trading day. However, this level is still far below the industry's prosperity threshold. More critically, downstream buyers' resistance to high prices has not dissipated, with inquiries cold and transactions stalled, pushing the market into a typical 'price without volume' standoff.
Low Operating Ratio Signals Industry Pressure
The sales-to-output ratio is a core indicator measuring the match between daily sales and production. A 34.7% ratio means that less than 40% of the day's output was sold, implying hidden inventory accumulation. Data from sample enterprises shows extreme divergence, ranging from 0% to 500%, with most firms in the 10%-40% band and a few at extremes. This suggests some mills may be clearing stock via discounts or contract orders, while others face sluggish sales entirely. Notably, the ratio rose 5.3 percentage points from the previous day, indicating partial liquidity rather than a full freeze. However, the overall weak demand tone persists, and price increases lack transaction support. For weaving mills, this means a longer procurement window, but if the ratio stays below 40%, the probability of discount destocking rises.
Upstream-Downstream Tug of War
The core contradiction lies in the tug between cost and demand. Upstream PTA and MEG prices remain elevated, squeezing polyester filament margins, leaving limited room for price cuts. Downstream weaving and garment enterprises, facing insufficient end orders, resist high raw material prices and prefer consuming existing inventories or buying hand-to-mouth. This 'hot upstream, cold downstream' pattern blocks price transmission, causing costs to accumulate at the midstream. Historically, a sales-to-output ratio persistently below 50% often precedes production cuts or promotions. The August 28 data does not yet trigger large-scale cuts, but if the stalemate persists, cash-strapped smaller mills may concede with discounts, dragging average prices lower. Buyers should avoid chasing highs and instead track inventory days and operating rates for clearer signals.
Regional and Product Divergence Complicates Procurement
Chemical fiber industrial belts such as Keqiao, Shengze, and Nantong show distinct demand patterns. Shengze, dominated by water-jet looms, has large demand for standard FDY and POY, but operating rates are generally low, with procurement limited to essential replenishment. Keqiao focuses more on DTY and differentiated products, with traders adopting a wait-and-see stance. This regional divergence means national average data may mask local opportunities—some fine-denier or functional filaments may still have stable orders, while standard specs face greater destocking pressure. Downstream mills should shift procurement strategy from price-driven to inventory-order coordination. If order visibility exceeds two weeks, consider locking in raw materials at dips; otherwise, maintain low inventories to avoid capital tie-up. Monitor polyester chip prices as a leading indicator for filament price moves.
Outlook: Short-term Stalemate, Mid-term Demand Recovery
In the short term, the polyester filament market is likely to remain range-bound, with the sales-to-output ratio hovering between 30% and 45%. The medium-term trend depends on the recovery of end textile and apparel consumption, especially the start of autumn/winter fabric orders. If the traditional September peak season materializes, downstream restocking could lift the ratio above 60%, supporting prices. Conversely, persistent weakness may trigger discount destocking. Participants should be wary of 'expectation gaps'—the market's high hopes for the peak season could lead to faster-than-expected price declines if orders disappoint. Therefore, flexible inventory strategies are advised, avoiding heavy bets in ambiguous directions.
