Behind the Full Sell-Through of Reserve Cotton: A Tight-Balance Signal in Textile Raw Materials

The state reserve cotton rotation is sending an unmistakable signal to the textile raw material market: downstream restocking pressure is stronger than most players expected. On September 23, China Reserve Cotton Management Co. offered 8,010.198 tonnes for sale and sold every tonne, a 100% clearance rate. This is not a one-day anomaly. Cumulative offerings reached 393,686.134 tonnes, with 390,579.168 tonnes sold, a cumulative clearance rate of 99.21%. When the sell-through rate stays above 99% for an extended period, the right question is not how much was sold, but why buyers are bidding so aggressively.

Market Context

On the price side, the September 23 average settlement was 16,648.97 yuan per tonne, up 13.75 yuan from the previous session, equivalent to 17,480.71 yuan per tonne for the 3128B grade. The highest accepted price was 17,460 yuan per tonne, the lowest 16,080 yuan, a spread of 1,380 yuan. Even within a single auction, resources of different grades and specifications remain sharply stratified.

Imported cotton deserves particular attention. Its average price matched the overall average at 16,648.97 yuan per tonne, also equivalent to 17,480.71 yuan for 3128B, with an average premium of 887.71 yuan per tonne. Imported and domestic cotton clearing at the same price but different quality suggests mills are making more sophisticated cost-performance trade-offs in their cotton blending, rather than simply chasing the cheapest lots.

Cumulative figures offer a longer reference frame. Through September 23, the cumulative average price was 17,196.73 yuan per tonne, equivalent to 17,853.16 yuan for 3128B. The cumulative high was 19,370 yuan, the low 16,010 yuan, with an average premium of 1,153.33 yuan. The cumulative average sits roughly 548 yuan above the daily average, an inversion indicating earlier auctions were even hotter. Recent prices have eased slightly but remain in an elevated band.

Industry Impact

A near-100% clearance rate transmits through the supply chain in layers. For ginners and traders upstream, sustained high clearance means marketable high-quality cotton is being absorbed quickly, narrowing the supply window before new-crop cotton arrives and reinforcing a hold-and-wait mentality.

For spinning mills in the midstream, the most direct hit is rigidly rising raw material costs. At 17,480.71 yuan per tonne for 3128B plus an average premium of 887.71 yuan, the effective delivered cost is already well above the annual budget line for many mills. If yarn prices cannot keep pace, spinning margins will be squeezed, and some small and medium mills may cut operating rates to avoid losses.

Downstream grey fabric, finished fabric and garment exporters face a more delayed but equally real impact. Every 500 yuan per tonne increase in raw cotton adds roughly 300 to 400 yuan per tonne to conventional yarn costs, which translates to about 0.05 to 0.10 yuan per metre at the grey fabric stage. For export orders priced in US dollars and already operating on thin margins, this cost is hard to pass on fully to overseas buyers and must largely be absorbed internally.

Regional textile clusters also bear watching. Purchasing rhythms in fabric hubs such as Keqiao and Shengze typically lead yarn quotations. Once reserve cotton clearance stays elevated, local traders will likely lock in yarn supply early, pushing spot yarn prices higher in the short term. Home textile and knitting clusters in Nantong and Foshan may show more divergent restocking behaviour due to seasonal order differences.

Practical Takeaways

For Buyers - Track the spread between the daily average settlement price and the 3128B equivalent. A narrowing spread often signals imminent spot cotton gains, so lock in short- to medium-term volumes early. - When imported and domestic cotton clear at the same price, compare micronaire, breaking strength and other key indicators rather than relying on the average price alone to avoid hidden quality losses. - For firms with fourth-quarter export orders, consider adding raw material price adjustment clauses or hedging cotton upside through forward pricing.

For Mills - Spinning mills should recalculate full costs under current blending plans. If the 3128B equivalent stays above 17,500 yuan per tonne, evaluate whether to cut operating rates or adjust product mix. - Grey fabric and finished fabric makers may modestly raise inventory turnover targets for standard items. In a rising raw material cycle, moderate stocking can yield more than the cost of capital tied up. - Small and medium mills should avoid concentrated restocking at auction peaks and instead adopt batch-by-batch, small-volume purchasing to smooth cost volatility.
