On July 27, trading in the polyester filament yarn market suddenly froze. Sample enterprises reported an average sales rate of only 25.4%, a sharp decline of 20 percentage points from the previous day. This figure means that over 70% of companies had sales rates below 30%, with some even recording zero transactions.
Behind the Sales Cliff: Plunging Polymer Costs
The immediate trigger was a severe drop in polymer costs. After signs of easing geopolitical tensions, international oil prices and upstream raw material costs fell in tandem, causing polymer costs to collapse. This cost-side shock quickly transmitted to the polyester filament yarn market, prompting downstream weaving enterprises to adopt a wait-and-see approach, sharply curtailing purchasing intentions.
Looking at the sales data released that day, only two companies achieved a 40% sales rate, while most were clustered in the 15%-30% range, with two companies reporting a 0% rate. This distribution clearly reflects extreme market pessimism—buyers almost entirely halted procurement, and sellers faced sudden inventory pressure.
Supply Chain Transmission: From De-stocking to Passive Inventory Buildup
In previous weeks, the polyester filament yarn industry had been on a rapid de-stocking path, with leading chemical fiber companies even doubling their half-year results. However, the data reversal on July 27 suggests this de-stocking process may be temporarily interrupted. After the plunge in polymer costs, downstream weaving mills generally expect further price drops for filament yarn, leading them to halt production rather than buy at high prices.
This 'buy on rising, not falling' mentality is common in textile raw material procurement, but the speed and magnitude of this decline exceed normal fluctuations. If polymer costs remain low, polyester filament yarn companies may face passive inventory buildup, potentially forcing price cuts or maintenance shutdowns in the next week or two to balance supply and demand.
Potential Impact on Textile Exporters
Polyester filament yarn is a core raw material for textile fabrics, and its price fluctuations ripple through the chain to grey fabric, dyeing, and garment stages. Exporters should watch for two risk points:
- Lower raw material costs may boost short-term profits, but if overseas clients simultaneously demand price reductions, profit margins could shrink.
- A sharp drop in sales rates often signals cash flow strain for companies, and some small- to medium-sized chemical fiber plants may dump inventory early, disrupting market pricing.
Over a longer horizon, this volatility underscores the industry's high sensitivity to geopolitics. Companies need more flexible cost hedging mechanisms rather than relying solely on single raw material channels.
