At 82.87 cents per pound, ICE cotton's December contract has given up the 83-cent level that bulls and bears had fought over for more than a week. A single-day decline of 0.66% looks mild, but the structural signal matters more: US upland net sales to China came in at zero for the week, and shipments fell 20% week on week. The export leg is visibly weakening.
Export Side: What Zero Sales to China Really Means
Cross-referencing US Department of Agriculture data with Chinese customs figures, US upland cotton net sales for the week ending September 10 reached 71,231 running bales, down about 30% from the four-week average. Net sales to China were zero for both the current and next marketing years. Shipments told the same story: 142,076 running bales left US ports, down 20% week on week, with only 2,437 bales destined for China.
For Chinese textile clusters, this is not merely a case of US cotton failing to sell. It reflects a deliberate pullback in forward pricing by Chinese buyers, squeezed by the domestic-international price spread, quota costs and limited order visibility. Mills in Keqiao and Shengze producing export greige and home textiles have shortened their booking cycles, shifting from quarterly stockpiling to monthly hand-to-mouth purchasing. That directly narrows the sales window for US cotton.
Substitutes: How Falling Oil Is Rewriting the Price Relationship
The second force pressuring cotton comes from energy markets. Improved Gulf supply prospects, rising traffic through the Strait of Hormuz and Saudi Arabia's resumption of Red Sea port exports pushed crude oil to a two-week low. Cheaper oil directly lowers polyester feedstock costs, reopening processing margins from PTA and MEG through to polyester staple fibre.
What does this mean? As the spread between polyester staple and cotton widens, downstream weaving and filling orders shift toward synthetics faster. For mills making blended yarns, home textile fillings and industrial fabrics, switching formulations is not costly. Once the cotton-polyester spread crosses a psychological threshold, substitution can happen within weeks. Cotton loses not just current orders but marginal demand share.
The macro backdrop is equally unfriendly. The Federal Reserve raised rates and signalled more to come, the dollar index strengthened, and dollar-denominated cotton became more expensive for overseas buyers. Higher US rates also raise carrying costs for traders. StoneX attributed part of the export decline to rate expectations, a view consistent with the shipment data.
Spot Market and Clusters: The 93.65-Cent Divergence
The Cotlook A Index stood at 93.65 cents per pound, up 230 points on the day, moving in the opposite direction to ICE futures. Such divergence typically signals tight supply of high-grade cotton in the spot market, or traders holding back at low prices. For Chinese mills, firm foreign spot prices combined with currency factors mean imported cotton landed costs have not fallen in line with futures.
Across industrial clusters, pressure concentrates at both ends: export-oriented mills with long orders cannot lock in feedstock costs, while domestic mills making differentiated products face more frequent formulation battles between cotton and synthetics. Small and medium enterprises in Nantong home textiles and Lanxi cotton spinning generally use small-batch, multi-frequency purchasing to hedge volatility, which further dilutes bulk buying demand in the short term.
A caveat: a single week of futures declines does not define a trend. If upcoming export sales reports continue to show zero for China, and Northern Hemisphere new crop pressure builds, the downside for cotton will truly open. Conversely, if oil stabilises or China begins a new restocking cycle, the rebound will be equally swift.
