A striking contrast emerged in the latest reserve cotton auction: the weekly average price climbed 220 yuan/ton above the cumulative average, yet the average premium dropped by 414 yuan/ton. During Aug 31-Sep 4, the turnover rate stayed at 100%, but buyers' willingness to bid aggressively has clearly cooled, signaling a shift from sentiment-driven to cost-driven purchasing.
Price-Premium Divergence: Spinners Turn Cautious
The weekly average price reached 17,520 yuan/ton, equivalent to 18,179 yuan/ton on the 3128 standard, up 1.3% from the cumulative average of 17,300 yuan since July 20. However, the average premium narrowed to 951 yuan/ton from the cumulative 1,365 yuan/ton, a 30% drop. A shrinking premium reflects diminishing consensus on future price increases, as more mills calculate affordable raw material costs based on their order profitability.
By grade, Xinjiang cotton averaged 17,682 yuan/ton (3128: 18,359 yuan/ton) with a premium of 1,131 yuan, while imported cotton averaged 17,511 yuan/ton (3128: 18,169 yuan) with a premium of 941 yuan. The price gap on the 3128 basis narrowed from 442 yuan in the cumulative phase to 190 yuan, indicating that imported cotton's price advantage is fading. Coastal mills relying heavily on imported fiber may need to reassess their sourcing mix.
Regional Concentration: A Subtle Sign of Capacity Migration
Shandong, Jiangsu, and Hunan accounted for 57.28% of the weekly volume, totaling 23,000 tons. While Shandong and Jiangsu are traditional textile powerhouses, Hunan's presence in the top three is noteworthy. The central province has been attracting relocated coastal capacity, backed by labor availability and policy incentives. The geographic distribution of reserve cotton purchases thus mirrors the ongoing shift in production capacity.
From July 20 to Sep 4, cumulative listed and traded volumes both reached 280,718 tons, with a 100% turnover rate. This reflects persistent restocking demand. Yet the cumulative average premium of 1,365 yuan/ton far exceeds the weekly figure, indicating that earlier bidding was more intense and the market is now returning to rationality. For small and medium mills, narrower premiums offer a chance to secure raw materials closer to the floor price, easing liquidity strains.
Transmission to the Supply Chain: High-Level Consolidation Likely
Reserve cotton prices influence futures and spot markets. The weekly average holding above 17,500 yuan provides cost support for downstream yarn, but the narrowing premium suggests that traders and mills are unwilling to pay excessive premiums for forward supply. If weekly releases continue at 40,000 tons, supply remains ample, and cotton prices may enter a high-level range-bound phase rather than rallying further.
For spinners, raw materials account for over 70% of costs; a 100-yuan swing in cotton prices affects per-ton yarn profit by roughly 150-200 yuan. The current narrowing premium improves the procurement window, but equivalent prices above 18,000 yuan still pressure yarn margins. In export markets, Southeast Asian yarn retains a price edge, so domestic mills must control raw material costs to stay competitive.
Outlook and Strategies
The persistent 100% turnover rate underlines strong underlying demand, but the shrinking premium warns of weakening upward momentum. Key factors to watch include daily release volumes, downstream weaving operating rates, and the pace of old-crop destocking ahead of the new harvest. If the Xinjiang-imported spread continues to narrow, more mills may shift toward reserve cotton, further pressuring spot prices.
