US cotton production was revised down, yet prices fell. The USDA's September WASDE report cut 2026/27 US cotton output to 13.2 million bales from 13.61 million in August, while ending stocks were lowered to 3.6 million bales from 4.0 million. Supply-side data tightened across the board. But ICE December futures closed at 86.06 cents/lb, down 2.45%, rather than rallying. This divergence suggests the market had already priced in tighter supply, and the report's release became a trigger for longs to exit.
Why Supply Contraction Failed to Support Prices
Regionally, the production cut was driven mainly by lower yields in the Delta and Southwest, with slight gains in the Southeast and West. This means the reduction was not a systemic nationwide shock but the result of localized weather disruptions, with limited impact on the global balance sheet. Traders understood this and did not read the report as a trend-defining bullish signal.
The demand side is more telling. For the week ending September 3, US upland cotton net export sales reached 73,854 bales, up 168% from 27,500 bales the prior week. On the surface, impressive. But net sales to China were zero, and zero again for the next marketing year. This marks the second consecutive week of Chinese absence from the US cotton market. Export shipments totaled 177,774 bales, down 6% week-on-week, with only 450 bales shipped to China — negligible.
Dual Pressure from Substitutes and Macro Factors
Lower oil prices were another drag. Signs of renewed Middle East negotiations pushed crude down, though it still posted a weekly gain above 8%. Falling oil directly lowers polyester fiber production costs, and polyester is cotton's primary substitute in spinning. As PTA and polyester staple fiber prices weaken with crude, mills naturally increase synthetic blends, squeezing cotton demand expectations.
The macro backdrop is equally unfriendly. The dollar index rose, and strong US consumer price data reinforced expectations that the Fed will hike rates in September to curb inflation. A stronger dollar makes dollar-denominated cotton more expensive for buyers holding other currencies, while rate-hike expectations dampen risk appetite across commodities. The Cotlook A Index stood at 98.20 cents/lb, up 100 points, but spot premiums failed to transmit to futures.
Transmission to China's Textile Supply Chain
China's two consecutive weeks of zero US cotton purchases have multiple causes. First, domestic commercial cotton inventories remain relatively ample, leaving mills with little incentive to restock. Second, the domestic-international price spread has not widened enough to open an import arbitrage window, and quota usage remains cautious. Third, downstream order recovery is limited, with export-oriented spinners and weavers watching the market rather than building forward positions at high prices.
In coastal Jiangsu and Zhejiang, cotton mills are buying hand-to-mouth, compressing raw material inventory cycles to under two weeks. Inland mills in Shandong and Henan rely more on state reserves and Xinjiang cotton rotation, reducing dependence on imported fiber. This shift in procurement strategy means Chinese buyers are unlikely to return to US cotton significantly in the near term.
For exporters, the key risk is bidirectional volatility in exchange rates and raw material costs. A stronger dollar plus rate-hike expectations could push up RMB-denominated import costs, while end-product export quotes struggle to rise in tandem. Margin compression from both ends is accumulating.
