On September 1, the polyester filament market experienced a sharp fluctuation in sales-to-production ratios: the average ratio among sampled enterprises dropped to 39.8%, a steep decline of 43 percentage points from the previous trading day's close. Just a day earlier, some manufacturers had reported ratios of 300%-400% during late-session volume surges, fueling optimism about a demand recovery. However, subsequent price hikes quickly met with downstream resistance, and market inquiries visibly cooled. This contrasting data reveals deep-seated contradictions in the current supply chain.
Market Logic Behind the Numbers
The dramatic swing in sales ratios is not an isolated event. The previous day's high ratios were largely driven by concentrated late-session buying, prompting some manufacturers to raise quotes in an attempt to convert short-term transactions into price support. But downstream users showed limited acceptance of higher prices, and their resistance intensified, causing the next day's ratios to plummet. The sample data shows that most enterprises recorded ratios between 15% and 40%, with only a few reaching 80%-150%, indicating significant divergence. This cycle of 'volume surge - price hike - resistance - decline' reflects a lack of sustained demand fundamentals, and short-term speculative buying cannot reverse the overall weak pattern.
Industrial Transmission and Inventory Pressure
As a core intermediate in the polyester chain, polyester filament's sales fluctuations directly affect upstream PTA and MEG markets as well as downstream weaving enterprises. The current low sales ratio implies slower inventory destocking at polyester plants, potentially forcing them to increase production cuts later. For downstream weavers, if raw material prices rise due to short-term speculation, their processing margins will be squeezed, especially without clear improvement in end-order demand. Consequently, weavers tend to purchase on a need-basis and maintain low raw material inventories. The cautious stance across the chain means price hikes lack support for downward transmission, eventually forcing polyester plants to concede.
Regional and Product Differentiation
Regionally, Jiangsu and Zhejiang, as major polyester filament production bases, serve as bellwethers. The sample data shows wide disparities among plants: some maintain higher shipments due to customer loyalty or differentiated products, while general-purpose items face greater selling pressure. Among product types, FDY, POY, and DTY may show different trends, with high-value-added products proving more resilient and regular varieties more susceptible to price wars. This divergence reminds buyers to focus on specific product types and supplier inventory structures rather than relying solely on industry averages.
Short-term Outlook and Operational Strategies
Looking ahead, polyester filament prices are likely to maintain a volatile and weak pattern. On one hand, cost-side support is limited; on the other, demand lacks explosive potential. As the traditional peak season of September approaches, terminal textile orders remain mediocre, and expectations for 'Golden September and Silver October' may need to be tempered. For polyester plants, price-support strategies might work briefly, but if sales continue to languish, production cuts to defend prices may become necessary. For downstream buyers, the window for raw material purchasing may appear after price corrections, and chasing rallies carries significant risk.
