The USDA's September supply and demand report trimmed 2026/27 US cotton production from 13.61 million bales to 13.20 million bales, while ending stocks were cut from 4.00 million to 3.60 million bales. Tighter numbers, yet ICE December cotton settled 2.45% lower at 86.06 cents per pound on the day the report was released. That decline tells a clear story: the market had already priced in the production cut, and the report's arrival simply gave bulls an exit to take profits.
Supply Side: A Cut Already Priced In
Regionally, the downgrade was not uniform. Delta and Southwest yields and output declined, while the Southeast and West posted modest gains. For traders, this offsetting pattern does not constitute a trend-level bullish signal, because the total reduction is limited and ending stocks remain in a relatively comfortable range.
More importantly, the USDA simultaneously raised its soybean production forecast, and CBOT soybean futures retreated after hitting a record high. Soybeans and cotton compete for planting area, so a stronger soybean outlook could squeeze cotton acreage next season. But that logic is medium- to long-term; near-term, the market cares far more about demand.
Crude oil also weakened that day, adding pressure on cotton. Lower oil prices directly reduce polyester fiber production costs, improving the substitution economics of synthetic fibers over cotton. When spinning mills adjust their fiber blends, cotton's demand elasticity weakens.
Demand Side: Export Surge Masks a China Gap
For the week ending September 3, US upland cotton net export sales for the current marketing year reached 73,854 bales, up 168% from the prior week, while shipments totaled 177,774 bales, down 6% week-on-week. On the surface, demand appears to be recovering. But break down the destination data, and net sales to China were zero for both marketing years, with shipments to China at just 450 bales.
Compared with net sales of 27,500 bales for the week ending August 27, this week's gain came almost entirely from markets outside China. US cotton exports are undergoing a customer-structure reshuffle away from China, with buying from Vietnam, Pakistan, and Turkey becoming the mainstay supporting export figures.
For China's textile clusters, this carries two implications. First, the flow of imported cotton resources is shifting, which could slow the drawdown of US cotton inventories in bonded warehouses. Traders may need to recalibrate their basis pricing strategies. Second, for export-oriented clusters such as Keqiao and Shengze, if end customers continue shifting capacity to Southeast Asia, yarn sourcing preferences will migrate accordingly.
The Cotlook A Index stood at 98.20 cents per pound on September 11, up 100 points. The spot market diverging slightly from the futures selloff suggests physical demand for high-grade cotton remains firm and the bearish sentiment is not universal.
Downstream Transmission: What Weak Cotton Prices Mean
For spinning mills, softer cotton prices ease raw material costs, but the transmission is not smooth. Mills are currently facing insufficient orders rather than expensive fiber. Falling cotton prices are unlikely to translate directly into better margins; instead, they may prompt downstream buyers to wait and see, delaying restocking.
For weavers and fabric makers, the spread between cotton and polyester staple fiber matters more. Weaker oil prices lower polyester costs. If the cotton-polyester spread continues to narrow, blended product ratios will tilt toward synthetics, eroding the cost advantage of pure cotton fabrics and intensifying price competition.
Exporters should watch the interplay between exchange rates and oil prices. The dollar index rose that day, and with international crude oil falling, dollar-denominated textile raw materials are broadly under pressure. The window for quoting orders may shorten, requiring more precise hedging and pricing timing.
