The August 28 sales-to-output data sends a warning to the chemical fiber market: the average sales-to-output ratio of polyester filament sample enterprises was only 34.7%, up 5.3 percentage points from the previous trading day, but this level remains in the low range for the year. More intriguing is the uneven distribution among sample enterprises—most fell between 20% and 30%, some even recorded zero sales, while an extreme outlier reached 500%. This divergence highlights the core issue in the current polyester filament supply chain: the cost-demand tug-of-war has entered a heated phase, and the market lacks directional consensus.
Signals Behind the Data
The sales-to-output ratio is a key indicator of how much of a day's production is sold. An average of 34.7% implies that over 60% of output was not converted into effective sales. The distribution shows that 20%-30% is the mainstream range, indicating systemic demand weakness rather than individual corporate mismanagement. The 500% outlier likely stems from a single large discount deal or bulk transaction, which cannot reverse the overall downturn but suggests the market is not entirely frozen—price-sensitive demand still exists.
Low sales-to-output ratios directly point to downstream resistance to high prices. High raw material costs coupled with sluggish recovery in end textile and apparel consumption have squeezed weaving enterprise profits, prompting them to reduce purchase frequency and trim raw material inventories. This cautious 'buy-on-demand' strategy, in turn, exacerbates polyester filament producers' inventory pressure, creating a vicious cycle. Notably, the ratio rebounded by 5.3 percentage points from the previous day, albeit limited, indicating that the market has not entered a unilateral decline, and some rigid demand is still entering opportunistically.
Upstream-Downstream Transmission and Regional Responses
The stalemate in the chemical fiber market is not isolated; its root lies in the broken cost transmission chain. Upstream PTA and MEG prices remain high due to volatile international oil prices. Polyester filament producers attempt to raise quotes based on cost, but downstream acceptance is extremely low, making price hike announcements ineffective. This 'hot upstream, cold downstream' pattern puts polyester plants in a dilemma: maintaining prices keeps sales-to-output ratios low, while cutting prices compresses profits further, potentially leading to losses. Industry public data indicates that current polyester filament processing spreads have narrowed to near break-even, and some small and medium enterprises face cash flow challenges.
From a regional perspective, weaving enterprises in major polyester filament consumption areas such as Shengze and Changxing have seen slight declines in operating rates, with some factories choosing staggered production or reducing shifts to cope with high raw material prices. In the Keqiao fabric market, inquiry enthusiasm has also cooled, with traders adopting a wait-and-see attitude until prices clarify. This upstream-downstream impasse is essentially a process of price rediscovery—when cost support and demand constraints pull in opposite directions, prices need time to find a new equilibrium. For foreign trade enterprises, RMB exchange rate fluctuations and uncertainties in overseas orders further complicate decision-making, making short-term orders preferred over long-term commitments.
Short-Term Outlook and Operational Strategies
In the short term, polyester filament prices are likely to maintain a narrow range-bound pattern. On the cost side, absent significant geopolitical events affecting oil prices, PTA and MEG are unlikely to experience sharp unilateral movements, providing a floor for polyester filament prices. On the demand side, the traditional 'Golden September and Silver October' peak season is approaching, but the strength of end-consumption recovery is questionable, and weaving enterprises' stocking intentions may be lower than in previous years. Overall, upward price movements lack demand support, while downward movements are cushioned by costs—stalemate may dominate. Whether the sales-to-output ratio can continue to recover will be a key indicator: if it stays above 50% for three consecutive days, a wave of restocking may follow; otherwise, be alert to the risk of price cuts due to inventory accumulation.
