Last week's reserve cotton auctions again hit a 100% transaction rate, yet the average premium narrowed to 951 yuan/ton from over 1,000 yuan in early July. This contrast reveals the true mood of mills: they cannot afford supply disruptions, but their price tolerance is shrinking.
Regional Signals in Transaction Structure
Provincial data shows Shandong, Jiangsu, and Hunan together purchased 23,000 tons, accounting for 57.28% of the weekly total. Shandong and Jiangsu are traditional cotton textile hubs, but Hunan's rise is noteworthy—its denim yarn and home textile capacity has expanded in recent years, boosting demand for mid-to-low grade cotton. This suggests reserve cotton is flowing from conventional mills to differentiated product bases. For buyers, shifts in regional purchasing heat can serve as a supplementary indicator of downstream demand structure.
Cumulatively from July 20 to September 4, reserve cotton listings and transactions both reached 280,718.02 tons, a 100% clearance rate, with an average price of 17,300 yuan/ton (discounted to 3128 grade at 17,949 yuan/ton). The weekly price gap between Xinjiang and imported cotton narrowed to 171 yuan/ton, but the cumulative gap widened to 418 yuan/ton. This narrowing suggests cooling bidding enthusiasm for imported cotton, possibly due to ample port inventories and reduced urgency for immediate delivery.
Triple Game Behind the Narrowing Premium
The premium drop from a cumulative 1,365 yuan/ton to 951 yuan/ton weekly is not demand shrinkage but expectation correction. First, the new crop season is approaching; mills may wait for machine-picked cotton supply, avoiding excessive capital lockup in reserve auctions. Second, cotton yarn prices have struggled to follow raw material gains, squeezing processing margins—every extra 100 yuan in fiber costs must be absorbed downstream where fabric mills resist price hikes. Third, policy certainty of continued reserve releases has created a consensus of adequate supply, cooling panic bidding.
For mills, the 100% clearance rate underscores rigid production demand—the cost of stopping lines outweighs paying a premium. But the low premium indicates cash-flow management has entered a meticulous phase, with mills assessing costs on a delivered basis rather than listed prices. If the discount to 3128 grade (18,179 yuan/ton weekly) continues to narrow against spot prices, the cost advantage of reserve cotton will erode, potentially loosening the clearance rate.
Transmission Effects on Industrial Clusters
Heavy purchasing by Shandong and Jiangsu enterprises reflects their operational rates' rigid demand for fiber. Shandong's home textile and technical textile clusters require stable medium-count yarn, which Xinjiang cotton from reserves can match in length and strength. Hunan's volume growth aligns with its denim weaving cluster's restocking rhythm, which follows an order-based procurement model sensitive to price fluctuations, thus favoring reserve auctions to lock in low costs.
Notably, imported cotton's cumulative premium (1,447 yuan/ton) significantly exceeds Xinjiang cotton's (1,147 yuan/ton), indicating mills still pay for quality premiums, especially in high-count yarns. However, the weekly narrowing to 941 yuan/ton may signal slower port inventory drawdown. Exporters should monitor the substitution elasticity between imported and Xinjiang cotton, avoiding overstocking a single variety amid currency fluctuations.
