Xinjiang Heat and Reserve Cotton Auctions Drive Weekly Price Surge, Exposing Deeper Chain Imbalances

In the first week of August, the domestic cotton market witnessed a rare unilateral rally: persistent extreme heat above 40°C in Xinjiang's core growing areas, combined with fully-subscribed state reserve cotton auctions at high premiums, pushed 3128B grade spot prices to 17,952 yuan/ton, a weekly gain of 2.93%. This figure reflects a fierce collision between upstream weather premiums and downstream weak demand, exposing deep imbalances in profit distribution across the textile chain.

Background

Extreme weather first broke the supply-demand balance. From August 3 to 6, temperatures in Turpan, Hami, and southern Bayingolin exceeded 40°C, with local extremes above 45°C, coinciding with the critical boll-setting stage. Heat accelerated water evaporation and weakened pollination, raising the probability of boll shedding. Market concerns over new-crop yields quickly translated into bullish sentiment in futures and spot markets. This weather premium is not short-term noise—it directly alters supply expectations for the new season and becomes a fundamental driver of price increases.

Meanwhile, state reserve cotton auctions saw zero unsold lots. During the week of August 3-7, all 40,100 tons offered were sold, with an average price of 17,014 yuan/ton, equivalent to 17,663 yuan/ton for 3128B grade, and an average premium of 1,497 yuan per ton. As of August 7, cumulative sales reached 120,259 tons with a 100% transaction rate and an average price of 17,173 yuan/ton. The high premiums and full subscription reflect tight spot supply and steady rigid demand from downstream mills—even in the off-season, production cannot stop.

Industry Impact

The strong raw material market and weak finished goods market form a "scissors gap." Terminal apparel and home textile orders remain sluggish; traders and fabric mills are cautious; yarn mills focus on destocking with only small price increases, mainly for conventional medium-count yarns. Cotton prices rose nearly 3% in a week, while yarn prices increased only marginally, squeezing spinning margins. Mills face a dilemma: buying risks high costs, not buying risks missing the window. This profit compression is forcing structural adjustments in procurement, with many small and medium mills turning to reserve cotton auctions to hedge costs—a primary risk-reduction tool.

For buyers, current price signals carry distortion risk. Weather premiums may overstate yield reduction expectations, and downstream demand has not genuinely recovered. If heat eases or crop conditions improve, prices may correct. For spinners, inventory strategies need flexibility: over-reliance on reserve cotton may face auction schedule uncertainties, while complete wait-and-see could miss locking-in opportunities. In the short term, profit distribution still favors raw materials, but weak finished goods follow-through will cap upside, creating a tug-of-war pattern.

Practical Recommendations

For Buyers - Purchase in batches to avoid chasing highs: Current prices include significant weather premiums; split purchases into 3-4 tranches based on actual orders, monitoring Xinjiang weather and reserve auction pace between batches. - Monitor reserve cotton release information: Actively participate in auctions to lock in cost advantages, but calculate storage and capital occupation costs. - Sign forward point-price contracts with mills: If expecting a short-term correction, use point-price models to defer purchase decisions to lower price ranges.

For Foreign Trade Companies - Shorten quotation validity: With volatile cotton prices, reduce validity from 30 days to 7-10 days and include raw material price linkage clauses in contracts. - Diversify sourcing: Beyond Xinjiang cotton, evaluate imported options (e.g., US, Brazilian) to spread single-origin risk. - Monitor exchange rates and logistics costs: Cotton price rises may push downstream product prices up; simultaneously calculate currency fluctuations and freight changes to avoid margin erosion.
