The first week of China's central reserve cotton auction delivered a strong signal: all 40,100 tons offered were sold at a 100% transaction rate with notable premiums. This directly reflects textile mills' urgent demand for quality cotton before the new crop arrives and indicates a tight spot market supply.
Price Divergence: Domestic Stability vs. Global Strength
Domestic cotton prices traded narrowly as reserve releases supplemented supply. Zhengzhou cotton futures averaged 15,980 yuan/ton, down just 77 yuan/ton from the prior week. The China Cotton Index (B) averaged 17,610 yuan/ton, down 49 yuan/ton. Globally, ICE cotton futures averaged 80.59 cents/lb, up 0.3%, holding above the 80-cent threshold. This rally was driven by improved U.S. export data—net sales for the week ending July 16 surged 49% week-on-week—and robust Brazilian exports, which averaged 7,322 tons/day in July, up 32% year-on-year.
The domestic-foreign price gap widened to 2,992 yuan/ton, as the International Cotton Index (M) averaged 88.45 cents/lb, translating to an import cost of 14,618 yuan/ton. This makes imported cotton increasingly cost-competitive relative to domestic supply.
Downstream Dynamics: Steady Yarn Prices, Rising Stockpiling
Cotton yarn prices remained stable. Domestic C32S combed yarn averaged 23,318 yuan/ton, while imported C32S yarn averaged 22,970 yuan/ton, still 348 yuan lower. Polyester staple fiber rose 129 yuan/ton to 7,584 yuan/ton, narrowing the cost advantage of synthetic alternatives.
More telling is mill behavior: surveys show high operating rates in Zhejiang's spinning sector, with export orders outperforming domestic ones. As the traditional peak season approaches, mills are increasingly restocking, evidenced by the 100% auction clearance rate. Reserve sales are easing supply concerns ahead of the new crop, but also capping price upside.
Macro Headwinds: Tariff Escalation and Regulatory Tightening
The external environment is turning more complex. On July 23, the U.S. Trade Representative announced 10%-12.5% tariffs on 60 countries under Section 301, with China facing a 12.5% rate. This will raise export costs for textile and apparel firms. The EU is also tightening: on July 20, it fined AliExpress €550 million under the Digital Services Act, raising compliance costs for cross-border e-commerce and potentially curbing small-parcel apparel exports.
Meanwhile, Middle East tensions persist, with daily Very Large Crude Carrier transits through the Strait of Hormuz dropping to just two from eight since late June. This has cut oil flows by about 12 million barrels and kept freight rates elevated, pressuring supply chains.
Growing Season Risks: Heat and Acreage Concerns
Domestic cotton growing conditions are generally normal, but heat risks loom. Xinjiang's ample sunshine and heat accumulation favor boll formation, but persistent high temperatures and low rainfall in southern Xinjiang are increasing local irrigation stress, raising the risk of boll shedding. Inland, Hebei and Shandong crops are on par with last year, Hunan's acreage is stable, but Hubei may see a reduction.
In summary, reserve auctions are providing near-term supply relief and capping price gains, while active mill demand is offering a floor. Cotton prices are expected to remain relatively stable in the near term, but attention should focus on weather developments in key producing regions and demand trends.
