The polyester filament market is showing a subtle signal: on August 6, Rongsheng Petrochemical (including Shengyuan) cut its POY quotes by 50-100 yuan/ton, with semi-dull POY 75/36 at 8,650 yuan/ton and 150/48 at 8,250 yuan/ton. Though the cut seems modest, it could mark a turning point in POY price trends. For weaving mills that rely on raw material cost pricing, this is not just a number change—it reopens room for price negotiation.
Background
Rongsheng Petrochemical is a core domestic polyester filament producer, and its price adjustments often serve as a bellwether. This cut covers multiple POY specifications, with black yarn 300/96 at 8,850 yuan/ton, showing varied declines across categories. From an industry logic perspective, the direct driver is a loose spot supply-demand balance—inventory pressure is rising, prompting the producer to cut prices to accelerate destocking. This "price-for-volume" strategy is not uncommon in the polyester chain, but it warrants caution when it occurs at the transition between off and peak seasons.
Deeper down, the POY price easing is closely linked to weakening upstream cost support. PTA and MEG prices have fluctuated within a narrow range recently, but downstream weaving operating rates have not improved significantly, leading to low POY sales ratios. Rongsheng's move essentially transmits inventory pressure upstream through price signals, while leaving room for future orders. For small and medium chemical fiber plants, this may trigger a chain of follow-up cuts, especially for those with low capacity utilization and weak pricing power.
Industry Impact
For buyers, lower POY quotes directly reduce raw material costs, but the "buy on rising, not falling" psychology may intensify wait-and-see sentiment. If the market believes prices still have room to fall, short-term purchasing may slow, further shrinking demand. Thus, the actual effect of this cut depends on market judgment of the bottom range—if prices find support in the 8,250-8,650 yuan/ton band, restocking may be stimulated; if they continue to decline, wait-and-see will dominate.
In the futures market, the spot price cut signal has reinforced bearish expectations, pressuring futures prices. This opens a window for hedging operations: traders holding POY inventory may consider short hedging to lock in prices, while downstream mills can monitor basis changes and selectively buy hedges. Notably, after the price cut, POY processing spreads may compress, which will have a smaller impact on highly integrated enterprises but will squeeze profits for polyester plants relying on external raw materials.
