The USDA's September WASDE report trimmed US cotton production for 2026/27 to 13.2 million bales, down 410,000 from August, while ending stocks were cut to 3.6 million bales. By conventional logic, tighter supply should lift prices. Instead, ICE December cotton settled 2.16 cents lower at 86.06 cents/lb, a 2.45% drop. That divergence signals a fundamental shift: cotton pricing is no longer driven by US balance sheets but by the willingness of global buyers to commit.
Why Futures Ignored the Bullish Supply Story
Positioning data tells the story. After the report, long positions were liquidated en masse rather than fresh shorts entering. Jon Marcus of Lakefront Futures and Options noted that traders concluded the data was "not bullish enough" and chose to take profits. The market had already priced in a smaller US crop; the marginal cut was insufficient to justify higher levels.
Deeper pressure came from substitute fibers. Crude oil fell on the day, dragging polyester feedstock costs lower and eroding cotton's relative cost advantage. Even with crude still up over 8% for the week, a single-session pullback can quickly reshape spinning mills' fiber selection. The decision between cotton and polyester ultimately comes down to the spread.
What Export Data Reveals About Shifting Demand
More important than futures prices is the structure of export sales. For the week ending September 3, US upland cotton net sales reached 73,854 running bales, up 168% from the prior week. Yet net sales to China were zero for both the current and next marketing years — the second consecutive week of zero Chinese bookings.
Against the 27,500 bales sold in the week ending August 27, the incremental volume clearly came from Vietnam, Turkey, Pakistan and other markets. Shipment data is equally telling: 177,774 running bales were exported, down 6% week-on-week, with only 450 bales destined for China. Chinese buyers are not only absent from new commitments but also scaling back on existing ones.
For US exporters, the capacity of Southeast and South Asian markets to fill the gap is being tested. But the order sizes, credit terms and settlement cycles in these markets differ markedly from China's concentrated purchasing model, making it difficult to fully offset the demand shortfall in the near term.
Transmission Through the Supply Chain
The Cotlook A Index stood at 98.20 cents/lb on September 11, up 100 points, showing a modest divergence from futures. Such spreads typically indicate residual firm demand in the spot market, particularly for high-count yarn orders requiring stringent fiber quality.
For Chinese textile mills, zero US cotton purchases do not equate to raw material shortages. Brazilian, Australian and Xinjiang cotton offer ample alternatives. However, fiber blending consistency and spinning uniformity must be re-validated, and the process adjustment costs of switching cotton sources should not be underestimated.
For traders, the biggest risk is not price direction but volatility. The supply-side narrative has been absorbed, and without Chinese buying to anchor demand, any macroeconomic headline can trigger outsized single-day swings.
