The polyester filament market is caught in a tug of war between costs and demand. Industry data on September 3 showed that the average sales-to-production ratio of sampled enterprises stood at only 25.8%, a sharp drop of 13.3 percentage points from the previous trading day. This figure not only falls far below the industry's prosperity threshold but also reflects the intense game between upstream and downstream players. With polymerization costs remaining high, manufacturers chose to raise quotations, yet downstream users responded with a cautious 'buy only what is needed' attitude, pushing the market into a typical dilemma of rising prices and shrinking volumes.
The Reality Behind the Data
The sales-to-production ratio is a core indicator of the chemical fiber market's health. A reading of 25.8% means that only a quarter of the day's output was absorbed by the market, with inventory pressure quietly building. The distribution among sampled enterprises ranged from 0% to 90%, showing an unusual divergence—some companies saw almost zero transactions, while a few maintained over 90% of their output sold. This polarization suggests that demand hasn't vanished entirely but is highly concentrated among suppliers with price advantages or product differentiation.
On the cost side, high polymerization costs are the main driver of firm prices. They directly raise the cash cost curve of polyester filament, forcing manufacturers to pass on pressure downstream after their margins are squeezed. However, the recovery of terminal textile and apparel orders is insufficient to absorb price increases, creating a negative feedback loop of 'cost-push inflation, demand resistance, and declining sales ratios.' Notably, this stalemate has persisted for several days; both September 2 and 3 reports showed low ratios, indicating that the market is not experiencing short-term fluctuations but has entered a phase of trend adjustment.
The Transmission Mechanism Is Failing
Under normal circumstances, cost increases would smoothly transmit through the industrial chain to fabrics and garments. But this time, the transmission chain is clearly blocked. Downstream weaving enterprises face a dual squeeze: higher raw material costs on one hand, and an inability to raise their own product prices on the other, further compressing their profit margins. Some weaving mills have chosen to reduce operating rates or extend raw material inventory turnover cycles, buying time in hopes of cost declines. While this strategy alleviates short-term cash flow pressure, it may lead to concentrated restocking later, which could push prices up again and create new volatility.
For traders, the current low ratio presents both risks and opportunities. The risk is that if costs continue to rise while demand remains weak, inventory depreciation pressure will increase significantly. The opportunity lies in the possibility that once downstream players complete their destocking cycle, restocking demand may be released collectively, leading to a rapid rebound in the ratio. Historical experience suggests that a ratio around 25% often approaches a cyclical bottom, and a recovery is likely later, but its strength depends on whether costs can loosen substantially.
Market Expectations and Operational Strategies
In the short term, polyester filament prices will maintain a high-level range-bound pattern, with limited downside but lacking demand support for upward movement. The trend of polymerization costs remains the decisive variable. If crude oil or PX prices fall, cost easing may prompt manufacturers to offer discounts to boost sales ratios; conversely, if costs continue to rise, manufacturers will be more inclined to hold prices firm, but ratios may drop further. For textile enterprises, it is not advisable to blindly chase price increases or panic sell at this time. Instead, they should closely monitor cost changes and terminal order signals.
From a medium-to-long-term perspective, this tug of war may accelerate industry consolidation. Small and medium-sized manufacturers lacking cost control capabilities and customer loyalty may be forced to cut production or exit, while companies with scale advantages and product innovation capabilities are poised to capture larger shares when demand recovers. The structural adjustment of the polyester filament market may be progressing quietly in this 'slow knife' manner.
