Polyester Filament Yarn Prices Tumble: A Signal of Tilting Supply-Demand Balance in Polyester Chain

Polyester filament yarn prices have shown a clear sign of easing. Shaoxing Jiabao recently lowered spot prices across its entire polyester FDY range—including semi-dull FDY 75D/36F at 8410 yuan/ton and bright FDY 150D/48F at 8610 yuan/ton—reflecting a broader industry trend of mounting inventory pressure and softening demand.

Supply-Demand Dynamics Behind the Price Cut

This price adjustment is not an isolated event. Industry data shows that operating rates in the Jiangsu-Zhejiang polyester filament sector have stayed above 85% since June, while downstream weaving mills have cut their utilization rates from a peak of 75% to around 68%. The supply-demand imbalance is evident: sales-to-output ratios have fallen below 70% for consecutive days, and inventory days have climbed past 25. Shaoxing Jiabao, a mid-sized producer in the region, is mirroring the broader industry’s stockpiling stress.

The product mix of the cuts is revealing. Almost all standard specifications of semi-dull and bright FDY were reduced, indicating a widespread slowdown in demand for mainstream items. The 150D/96F, a workhorse grade for weaving, dropped to 8110 yuan/ton—about 200 yuan/ton lower than last month—approaching the cash cost for some producers. Further declines could force smaller mills to cut output or shut down.

Futures vs. Spot: A Market Sentiment Divergence

In contrast to the weak spot market, the Zhengzhou Commodity Exchange’s polyester staple fiber futures (2609 contract) closed at 6858 yuan/ton on July 6, up 74 yuan/ton from the previous session, with open interest rising by 15,420 lots. The strength in futures suggests some capital remains bullish on long-term prices, but the sluggish spot market is dragging down overall polyester sector sentiment.

This divergence encourages caution among traders. Downstream buyers, seeing futures rise, may delay purchases hoping for a spot price rebound, while mills with high inventories are forced to cut prices further to move goods. This standoff is unlikely to resolve quickly, and polyester filament prices are expected to consolidate in a narrow range with more downside risk than upside potential.

Transmission Effects Along the Chain

Lower polyester FDY prices directly reduce raw material costs for weaving mills. For grey fabric producers that rely heavily on polyester filament, lower input costs mean improved immediate margins. However, if downstream fabric prices follow suit, those gains may not stick—it all depends on final order volume.

• At the polyester stage: PTA and MEG prices have been stable recently, so FDY price cuts will compress processing margins and could force higher-cost capacity out of the market.
• At the weaving stage: grey fabric inventories are also high. Lower raw material costs won’t immediately boost operating rates but will alleviate cash flow pressures.
• At the trading stage: intermediaries remain on the sidelines, with transactions limited to urgent small lots; large orders are scarce.

Practical Advice

For Buyers - Current prices are at a relative low, but not necessarily the year’s bottom. Purchase based on immediate needs and consider staggered buying to mitigate risk. - Monitor the spread between futures and spot. When futures premiums exceed 200 yuan/ton, consider forward point pricing to lock in costs. - Focus on smaller, inventory-heavy mills for negotiations, as they are more likely to offer discounts.

For Exporters - Build price fluctuation buffers into export quotes. Use short-term floating pricing mechanisms to avoid losses from a potential raw material rebound. - Track polyester yarn prices in Southeast Asia; the current domestic price decline may enhance Chinese products’ export competitiveness. - Utilize futures hedging tools, especially polyester staple fiber futures, to manage raw material price risk.
