China's reserve cotton auctions have now posted consecutive sell-outs. On September 24, all 8,005.611 tonnes offered were sold, a 100% clearance rate, at an average price of 16,662.82 yuan per tonne, up just 13.85 yuan from the previous session. The number itself is unremarkable, but the sustained full clearance points to a near-rigid demand for deliverable cotton. The 3128B-equivalent price came in at 17,448.82 yuan per tonne, almost identical to the day's highest transaction price of 17,420 yuan, indicating a narrowing bidding range and a high degree of consensus among buyers on acceptable price levels.
Deal Structure: The Imported-versus-Xinjiang Spread
All of the day's volume came from imported cotton, averaging 16,662.82 yuan per tonne with an average premium of 855.82 yuan. In cumulative terms, imported cotton has averaged 17,231.17 yuan per tonne, while Xinjiang cotton has averaged 16,997.17 yuan, a spread of 234 yuan. That gap is not large, but its direction matters. Imported cotton has consistently commanded a premium in the reserve auctions, suggesting mills are willing to pay extra for specific quality parameters.
Cumulatively, through September 24, 401,691.7451 tonnes have been offered and 398,584.7791 tonnes sold, a clearance rate of 99.23%. The cumulative average price stands at 17,186 yuan per tonne, or 17,845.04 yuan on a 3128B-equivalent basis, with an average premium of 1,147.35 yuan. Prices have ranged from a high of 19,370 yuan to a low of 16,010 yuan, a spread exceeding 3,300 yuan, reflecting significant quality variation across batches and origins.
Price Signals: What the 3128B Spread Reveals
The day's 3128B-equivalent price of 17,448.82 yuan sits nearly 400 yuan below the cumulative average of 17,845.04 yuan. This suggests that recently auctioned reserve cotton is pricing below the longer-term mean, likely reflecting either a shift in the grade mix of offered resources or more conservative bidding. For spinning mills, the 3128B-equivalent price is a key anchor for raw material cost calculations, and the current level implies continued support for yarn production costs.
The average premium of 855.82 yuan is well below the cumulative average of 1,147.35 yuan. Narrowing premiums typically indicate either less aggressive bidding or a smaller gap between starting prices and market values. For buyers, this is a window signal worth watching: if the trend persists, the effective landed cost from future auctions could drift lower.
Industry Impact: Upstream-Downstream Transmission and Regional Response
Sustained high clearance rates cut both ways for downstream spinners. On one hand, greater certainty in raw material supply gives mills a more stable cost basis for production planning. On the other, the variable quality of reserve cotton means higher sorting and blending costs, particularly for mills producing medium-to-high count yarns, where the ratio of imported to Xinjiang cotton directly affects yarn quality.
From a regional perspective, mills in Jiangsu, Shandong and Henan are the main participants in reserve auctions. With nearly 400,000 tonnes cumulatively sold, a significant volume of lower-priced reserve cotton has entered circulation, helping to dampen spot market volatility. However, the pace and volume of future reserve releases will shape procurement strategies; if offered volumes shrink, spot cotton prices could find additional support.
