Analysis review

As of midday trading on October 23, 2025, the price of West Texas Intermediate (WTI) crude oil was trading around $58.20 per barrel, a slight increase from the previous day. Data from the early morning of the same day showed that the latest price of WTI crude oil futures was $59.86 per barrel, up 0.81%; the latest price of Brent crude oil futures was $64.04 per barrel, down 0.48%. The previous day (October 22), international oil prices had rebounded significantly. The price of light sweet WTI crude oil for December delivery was $58.50 per barrel, up 2.2%; the price of Brent crude oil for December delivery was $62.59 per barrel, up 2.07%.

According to news on October 23rd, the arrival of cold fronts had led to a rebound in demand for winter fabrics, supporting the order side. Just-in-time orders had driven production and sales to increase. At the end of trading on October 21st, the average production-sales ratio of polyester filament sample companies soared to 367.9%. Downstream users were more willing to stock up, which had a certain boosting effect on prices. However, for some time before this, downstream weaving companies had been cautious in purchasing, mainly focusing on replenishing inventory for just-in-time needs. The recovery of demand during the "Golden September and Silver October" peak season was weak, and the inventory of grey fabrics was high. The total number of new orders did not see a significant increase, which suppressed the rise in polyester filament prices.

Market outlook

Polyester filament prices are expected to remain volatile and stronger in the short term, but upward potential may be limited. With the arrival of cold fronts, demand for winter fabrics began to pick up. On October 21st, the average production-sales ratio of sample polyester filament companies soared to 367.9%. If demand continues to increase, it will provide some support for prices, and some varieties may stabilize, but a significant overall increase is unlikely.
