The USDA's September supply and demand report cut 2026/27 US cotton production from 13.61 million bales to 13.20 million bales, while ending stocks fell to 3.60 million bales. Both revisions pointed toward tighter supply. Yet ICE December cotton settled 2.16 cents lower at 86.06 cents per pound, a drop of 2.45%. A bullish report producing a selloff tells you the market was not trading the data itself but the gap between the data and what traders had already priced in. When the production cut failed to exceed the bullish bets already on the books, the report's release became a starting gun for profit-taking rather than a catalyst for new longs.
The Expectation Gap Is the Real Price Driver
Regionally, the Delta and Southwest saw both yields and output decline, while the Southeast and West posted modest gains. This offsetting pattern matters because it means the overall reduction was not the product of a broad weather disaster but the net result of localized disruptions. For traders, regional divergence lowers the panic premium on supply, since losses in one belt can be partially absorbed by gains elsewhere.
More importantly, the market had been trading the production-cut narrative for weeks, leaving long positions relatively crowded. When the final numbers offered no additional bullish surprise, funds chose to exit rather than add. This is a classic buy-the-rumor, sell-the-fact dynamic. For the textile supply chain, a short-term futures pullback does not equal a structural decline in raw material costs. If anything, it may open a pricing window for mills looking to lock in forward coverage.
Export Surge Masks a Structural Gap
For the week ending September 3, US upland cotton net export sales reached 73,854 running bales, up 168% from 27,500 bales the prior week. Shipments totaled 177,774 bales, down 6% week on week. On the surface, export momentum looks strong. But break down the destinations and a different picture emerges: net sales to China were zero for both the current and next marketing years, with shipments to China at just 450 bales.
This means virtually all of the incremental US cotton export volume came from buyers outside China. Vietnam, Pakistan, and Turkey are providing the replenishment demand, while Chinese buyers remain absent. For domestic textile enterprises, this signals two things. First, the linkage between Chinese buying pace and US cotton prices is weakening. Second, domestic mill demand may be shifting toward Brazilian cotton, Australian cotton, or state reserve resources.
Substitution Pressure and Macro Headwinds
Crude oil fell on the day but still posted a weekly gain of more than 8%, with supply concerns from disrupted Middle East shipping routes far from resolved. Lower crude directly reduces polyester fiber production costs, creating substitution pressure against cotton. When PTA and polyester staple fiber prices soften alongside oil, spinning mills have a stronger incentive to raise the synthetic blend ratio in their cotton mixing plans, which in turn suppresses marginal cotton demand.
At the same time, a stronger dollar and robust US consumer price data have reinforced expectations of a September rate hike by the Federal Reserve. A stronger dollar raises the effective cost of dollar-denominated cotton for overseas buyers, echoing the zero-sales figure to China in the export data. The Cotlook A Index stood at 98.20 cents per pound on the day, up 100 points. The brief divergence between spot and futures suggests physical supply remains relatively tight, but the futures market is already trading a looser outlook further out.
