US cotton production was cut by 360,000 bales, yet ICE December futures settled 2.45% lower. That divergence tells us the real battle in cotton prices is not about total supply but about market expectations and positioning.
Data Breakdown: Why a Smaller Crop Failed to Lift Prices
The USDA's September WASDE report pegged 2026/27 US cotton production at 13.2 million bales, down from 13.61 million in August. The Delta and Southwest regions saw lower yields and output, while the Southeast and West edged higher. Ending stocks were trimmed to 3.6 million bales from 4.0 million.
On paper, supply is tightening. But the market had priced in a deeper cut. Once the report landed, traders read the numbers as looser than anticipated. ICE December cotton fell 2.16 cents to 86.06 cents/lb as bullish funds took profits, suggesting earlier rallies had already absorbed much of the减产 premium.
For Chinese mills, this means the window for foreign cotton procurement may stay open longer than expected. Futures declines typically take one to two weeks to feed through to the Cotlook A Index and port spot quotes. On September 11, the Cotlook A Index rose 100 points to 98.20 cents/lb, not yet reflecting the futures drop.
Export Structure: Volume Up, China at Zero
USDA weekly export sales showed net upland cotton sales of 73,854 bales for the week ending September 3, up 168% from 27,500 bales the prior week. Shipments reached 177,774 bales, down 6% week-on-week.
The critical detail is China. Net sales to China were zero for both the current and next marketing years, with shipments of just 450 bales. This structural shift means US cotton export growth is coming from Vietnam, Pakistan and Turkey, not China.
For Chinese buyers, US cotton availability is rising, but bargaining power is shifting. Southeast Asian spinners are filling the gap left by China. If their operating rates keep climbing, international cotton yarn quotes could rise, in turn affecting the cost-effectiveness of China's yarn imports.
Substitute Pressure: Weak Oil Is the Hidden Drag
News of potential Middle East talks pushed oil lower, though crude still posted a weekly gain of over 8%. Diesel prices hit record highs, and attacks on Middle East shipping routes raised concerns about prolonged supply disruption.
Lower oil prices directly reduce polyester fiber production costs. Cotton and polyester staple fiber are substitutes in yarn blends. When polyester feedstock prices fall, mills have a stronger incentive to raise polyester ratios in blended products. This is a marginal negative for pure cotton yarn demand and another channel weighing on cotton futures.
Meanwhile, Chicago soybean futures retreated from record highs after the USDA raised its soybean production forecast. Grains and cotton compete for planting area. Changes in soybean returns will influence farmers' planting intentions for the next season, shaping forward supply expectations.
