The PTA main contract rose nearly 1% in a single day, with staple fiber following suit, while cotton and cotton yarn both closed lower. The night session data on June 5 reveals a trend that is not surprising but worth noting: the price trajectories of the polyester chain and the cotton chain are diverging at an accelerating pace. For the textile industry, this means the cost transmission mechanism of raw materials has developed structural cracks, and procurement windows for different categories are shifting out of sync.
Looking purely at the absolute percentage changes, a 0.93% rise in PTA and a 0.62% rise in staple fiber may seem modest. But placed in the current industrial context, this signal needs to be amplified. PTA prices standing at 6,304 points are the combined result of firm PX cost support and high polyester operating rates. Staple fiber, as a direct downstream of PTA, follows logically—raw material push plus its own moderate inventory levels.
In contrast, cotton and cotton yarn, with the 2609 contract at 15,940 and 22,360 points respectively, fell in the opposite direction. Cotton's repeated struggle around the 16,000-point mark and eventual breach reflect market concerns over increased production expectations in Xinjiang and insufficient downstream orders. Cotton yarn's decline indicates that the terminal weaving sector has not formed effective absorption.
Cost Transmission Misalignment
The core driver of this divergence lies in different raw material cost structures. PTA's upstream PX prices remain supported by international oil prices and Asian refinery maintenance, while cotton prices are more influenced by domestic supply and demand fundamentals. Good weather in Xinjiang, a looser new-season output expectation, and rising import arrivals have gradually increased supply pressure.
From a processing profit perspective, at current staple fiber prices, polyester factories still have reasonable profit margins, with operating rates above 85%. Cotton textile enterprises face a tougher situation—cotton yarn prices fall faster than cotton, squeezing spinning profits. Some small and medium-sized cotton mills have begun to proactively cut production. This profit inversion will further dampen cotton procurement demand, forming a negative feedback loop.
For chemical fiber clusters like Shengze and Keqiao, the strength in PTA and staple fiber means cost support remains, but whether downstream grey fabric and printing/dyeing sectors can absorb the price increases remains to be seen. For cotton textile belts like Nantong and Lanxi, the simultaneous decline of cotton and cotton yarn suggests destocking pressure will not ease in the short term.
Inventory and Procurement Strategy Divergence
Current inventory structures show clear divergence. In the chemical fiber sector, staple fiber factory inventory stands at 10-15 days, a healthy range; downstream yarn enterprises maintain just-in-time procurement without large-scale hoarding. In the cotton sector, inventory pressure is greater. Although cotton commercial stocks are declining, cotton yarn inventories continue to accumulate, especially for medium and low-count yarns, with some warehouses reporting overflow.
This inventory divergence directly affects procurement behavior. Chemical fiber enterprises maintain relatively stable procurement cycles; small price increases do not trigger panic replenishment. Cotton textile enterprises are more inclined to wait for further price declines before purchasing. For foreign trade enterprises, this divergence means order-taking strategies need adjustment.
