US cotton production was trimmed by 210,000 bales and ending stocks by 400,000 bales, yet ICE December cotton tumbled 2.45% on the day. This divergence between ostensibly bullish data and a bearish tape is the clearest signal yet that the market's pricing logic has shifted. Cross-referencing China Customs data with USDA public reports, the focus is no longer absolute output but the widening gap between a broadly comfortable global supply picture and persistently weak demand.
Background: Why a Seemingly Bullish Report Triggered a Selloff
The USDA's September World Agricultural Supply and Demand Estimates put 2026/27 US cotton production at 13.2 million bales, down from 13.61 million in August. Regionally, the Delta and Southwest saw lower yields and output, while the Southeast and West posted slight gains, painting a mixed picture. Ending stocks were also revised down to 3.6 million bales from 4.0 million.
On static numbers, lower output and stocks should support prices. The market reacted in the opposite direction: ICE's most-active December contract fell 2.16 cents to settle at 86.06 cents/lb, a 2.45% decline. This means the market had already priced in a tighter supply outlook, and once the report landed, long positions were liquidated rather than added to.
Notably, news that the Middle East may restart a fresh round of negotiations weighed on oil prices, though crude was still on track for a weekly gain of more than 8%. Lower oil directly reduces polyester fiber production costs, strengthening the competitiveness of cotton's substitute and adding further pressure on cotton prices. This transmission chain has direct implications for the substitution relationship between chemical fibers and cotton spinning in China.
Industry Impact: Diverging Export Structure and Substitute Pressure
The USDA weekly export sales report showed that for the week ending September 3, current-crop US upland cotton net sales rose 168% week-on-week to 73,854 bales, but net sales to China were zero. Next-crop upland cotton net sales added 2,464 bales, again with zero net sales to China. Shipments for the week totaled 177,774 bales, down 6% from the prior week, with only 450 bales shipped to China.
Compared with net sales of 27,500 bales for the week ending August 27, this week's rebound was almost entirely driven by markets outside China. This structural shift means Chinese buyers' marginal influence on US cotton pricing is diminishing, and purchasing rhythms in alternative origins such as Vietnam, Pakistan, and Turkey will become the key variable for US cotton exports.
For China's textile chain, zero US cotton sales to China does not translate directly into a supply gap. Domestic cotton inventories, import quota policy, and Xinjiang cotton processing progress are the core factors determining actual tightness on the raw material side. However, weaker US cotton prices transmit through the domestic-international price spread, influencing ginners' purchasing sentiment and traders' hedging strategies.
The Cotlook A Index stood at 98.20 cents/lb on September 11, up 100 points, diverging somewhat from the ICE board. The relative firmness of the spot index suggests that concerns over immediate supply have not fully dissipated, possibly linked to logistics rhythms in certain origins.
