78.88 cents per pound. That was the settlement for ICE December cotton on October 2, a gain of 1.44% on the day. But the more important number is the weekly loss: 4.6%. The single-session rebound was modest, while the weekly decline was decisive. For the textile supply chain, the real issue is not one day's price move but the repricing of US cotton quality premiums.
Why Weather Premiums Are Not Holding
Heavy and persistent rain across US cotton belts has arrived during the boll-opening window. Once bolls crack open, exposed fiber is directly vulnerable to rain and strong winds, making quality degradation almost inevitable. A risk management advisor noted that the rain is not over and the market is in a clear downtrend, meaning weather is only a brief disruption within a broader weak trend.
The impact is twofold: fiber length and strength decline, reducing spinnability, while thunderstorms and strong winds can cause yield losses. Both point to the same outcome: less high-quality cotton available, while medium- and low-grade supplies face greater selling pressure.
For Chinese mills, this means the share of US cotton arrivals suitable for high-count yarn production may shrink, while discounts for lower grades could widen. Buyers sticking to conventional grade structures may face passive cost increases.
Export Data and Oil Prices Weigh on Sentiment
USDA's latest export sales report showed that for the week ending September 24, current-crop upland cotton net sales reached 202,567 bales, down 12% from the previous week but up 101% from the four-week average. Net sales to China were 38,370 bales, while next-crop net sales to China were zero. Shipments totaled 149,507 bales, down 9% week-on-week, with only 1,323 bales shipped to China.
The signals are not encouraging. The weekly decline suggests near-term buying is slowing, while zero next-crop sales to China reflects strong forward-order caution. Lower shipments mean contracted cotton is also being delayed, pointing to reduced liquidity in the trading chain.
Meanwhile, G7 nations agreed to release 100 million barrels of strategic oil reserves through the IEA, starting immediately and lasting four months, with a concentrated release of diesel in the first 20 days. International oil prices fell, with European diesel futures dropping over 4%. Lower oil prices reduce the cost of polyester, a petroleum-based substitute for cotton, weakening cotton demand support.
The Cotlook A Index stood at 88.35 cents/lb on October 2, down 80 points. Futures and spot markets are weakening together, suggesting the price decline reflects genuine supply-demand softness rather than a technical correction.
Transmission to Chinese Industrial Clusters
Textile clusters in Keqiao, Shengze, and Nantong face two direct variables: the repricing of US cotton quality premiums and the strengthening substitution effect from polyester.
For mills focused on high-count yarns, if high-quality US cotton availability declines, they may need to switch to Australian, Brazilian, or Xinjiang cotton for blending. But switching raw materials requires revalidating process parameters and yarn specifications, with non-negligible time and trial costs.
For mills producing medium- and low-count yarns, polyester price declines create more direct substitution pressure. If polyester staple fiber prices continue to fall, some blended orders may shift further toward synthetics, compressing the share of pure cotton yarn orders.
Exporters need to watch order timing. Zero next-crop US cotton sales to China indicate weak forward buying, as overseas buyers may be waiting for a clearer price bottom. This caution will transmit upstream, reducing inquiries and lengthening lead times in yarn and grey fabric segments.
