Heatwave and Reserve Cotton Tightness Push Spot Prices Up Nearly 3% in a Week: Signals of Profit Redistribution Along the Chain

On August 10, the domestic standard 3128B grade cotton spot price settled at 17,952 yuan per ton, up 2.93% in a single week. This figure reflects two combined forces: extreme heat in Xinjiang threatening new crop yields, and reserve cotton auctions being fully subscribed. The contrast between strong raw materials and weak downstream textile demand is stark, signaling a rapid redistribution of profits along the industry chain.

Event Background

Xinjiang cotton is in the critical stage from full bloom to boll expansion, where field management directly determines annual yield. From August 3 to 6, core planting areas including Turpan, Hami, and southern Bazhou experienced persistent extreme heat, with temperatures exceeding 40°C and local peaks above 45°C. The heat coincided exactly with the boll-setting window, accelerating water evaporation, weakening pollination, and significantly raising the probability of boll shedding. Market concerns over reduced yields quickly escalated, providing fundamental support for higher prices.

Meanwhile, the reserve cotton auction market showed a red-hot trend of full subscription. During the week of August 3-7, 40,100 tons of reserve cotton were listed and all sold, with a 100% transaction rate. The average transaction price was 17,014 yuan/ton, equivalent to 17,663 yuan/ton for 3128B grade, with an average premium of 1,497 yuan per ton. As of August 7, cumulative reserve cotton transactions reached 120,259.425 tons, maintaining a full subscription rate, with an average price of 17,173.33 yuan/ton. The high premiums and zero failed auctions directly confirm tight spot supply and stable downstream restocking demand.

Industry Impact

The strength at the raw material end contrasts sharply with downstream weakness. Terminal orders for apparel and home textiles remain soft, and traders and fabric mills are cautious in purchasing. Most yarn enterprises focus on destocking, keeping prices stable with only slight upward adjustments, mainly selling conventional mid-count carded, combed, and compact yarns.

The biggest contradiction in the chain is that cotton price gains far exceed yarn price increases, narrowing the spread and squeezing spinning margins. Under profit pressure, mills resist high-priced new cotton, adopt a wait-and-see attitude in spot purchasing, and control restocking volumes. To hedge costs, many small and medium-sized mills have shifted to reserve cotton auctions, which offer clear cost advantages and have become a key cost-reduction tool.

In the short term, bullish factors dominate: persistent heat in Xinjiang threatens production, and high premiums in reserve auctions reflect tight supply. However, weak downstream demand won't recover quickly, and mill profit pressure and cautious purchasing will cap upside potential. The industry is likely to maintain a divergence of strong raw materials and weak finished goods, with cotton prices oscillating at high levels.

Practical Advice

For Buyers - Monitor Xinjiang weather and crop progress; if heat persists, consider locking in forward supply early while managing inventory costs. - Use reserve auction windows to compare price gaps with spot and participate selectively to lower overall cotton costs. - Negotiate long-term pricing with mills to share raw material risk and avoid bearing all price increases.

For Exporters - Add price adjustment clauses linked to raw material costs and shorten quotation validity to mitigate contract risks from cotton price swings. - Watch exchange rates and the domestic-international cotton price gap, adjust sourcing sources to balance cost and lead time. - Prioritize short and small orders to maintain flexibility and avoid inventory write-downs if cotton prices fall.
