The cotton market's tug-of-war took a decisive turn in early August: extreme heat hit Xinjiang's key boll-setting period, while state reserve auctions saw full-premium turnovers. By August 10, the domestic 3128B grade spot price reached 17,952 CNY/ton, up 2.93% in a single week—far outpacing yarn price adjustments. For spinners, the widening gap between soaring raw material costs and sluggish finished-product pricing is redefining procurement strategies and profit margins for the second half.
Heat-Driven Yield Fears Priced In
From August 3 to 6, core cotton regions including Turpan, Hami, and southern Bayingolin experienced persistent extreme heat, with temperatures exceeding 40°C and local peaks above 45°C—coinciding precisely with the critical flowering-to-boll-setting growth stage. Accelerated water evaporation and weakened pollination raised the probability of flower and boll shedding, fueling concerns about lower yields. Such worries are not mere sentiment: this window determines unit output, and once heat damage is confirmed, expectations of tighter supply directly feed into forward prices. Traders responded by pushing spot and futures higher, effectively converting weather risk into a tradable market factor.
Reserve Auctions Signal Tight Physical Supply
Corroborating the heat narrative, state reserve cotton auctions turned exceptionally hot. During the week of August 3-7, 40,100 tons were offered and fully sold, with a 100% turnover rate. The average price was 17,014 CNY/ton, equivalent to 17,663 CNY/ton for 3128B grade, with an average premium of 1,497 CNY/ton. Extending the timeline, cumulative reserve sales through August 7 reached 120,259.425 tons, with an average price of 17,173.33 CNY/ton (17,801.48 CNY/ton for 3128B). Zero failed lots and high premiums directly expose tight physical supply. For small and medium spinners, reserve cotton offers better value than local market cotton, making aggressive bidding a primary tool to lower blended costs and hedge against price spikes. This structural behavior reinforces the bidding cycle—scarcity fuels demand, which in turn tightens supply further.
Profit Reconfiguration Forces Structural Adjustments
The strength upstream contrasts sharply with a sluggish downstream off-season. Terminal apparel and home textile orders remain weak; traders and fabric mills are cautious; yarn mills prioritize destocking, keeping prices stable with only tentative small increases. The core contradiction: cotton rose nearly 3% in a week, while conventional yarns (medium-count carded, combed, compact) saw far smaller increases, narrowing the spread and squeezing spinning margins. Under profit pressure, mills resist high-priced new cotton, adopting a wait-and-see stance on spot point-price purchases and controlling restocking volumes. Meanwhile, many small and medium yarn factories shift procurement toward reserve cotton, substituting it for part of market cotton to cut blended costs. This 'voting with feet' behavior is reshaping inventory strategies and cost-control models.
Near-Term Pattern Unlikely to Change
Overall, bullish factors remain dominant in the short term: Xinjiang heat threats persist, yield-reduction expectations are hard to falsify quickly, and high-premium reserve sales continue to reflect tight supply, underpinning prices. However, downstream demand weakness cannot be repaired quickly, and mills' profit pressure and cautious buying will cap upward room. The chain is likely to maintain a 'strong raw materials, weak finished goods' divergence, with cotton price gains failing to pass through smoothly to yarn and fabric. For buyers and exporters, this demands more refined cost management and greater flexibility in inventory turnover and order pricing.
