The cotton market saw a sharp rally on July 7. The ICE December contract surged 2.99 cents, or 3.82%, to close at 81.29 cents per pound, hitting an intraday high of 81.3 cents – the highest since June 2. This was no isolated speculative move; it was driven by a threefold confluence of drought in producing regions, rising polyester costs, and renewed demand expectations.
Weather: Texas Drought Drags Down Crop Ratings
The USDA's weekly crop progress report released on July 6 showed the US cotton good-to-excellent rating fell to 46%, down from 48% the prior week and well below the 52% recorded a year earlier. Persistent drought in Texas, the largest cotton-producing state, combined with generally poor conditions across major growing areas, has clouded the new crop outlook. While the squaring rate of 49% is above the prior week's 37% and slightly ahead of the five-year average of 47%, the accelerated growth pace has not alleviated market concerns about potential yield losses.
For textile mills, the declining good-to-excellent rating signals that high-grade exportable US cotton for the 2026/27 season may tighten. In previous years, the market focused more on planted acreage; this year, weather has become the dominant pricing factor.
Substitution Channel: Oil Spike Lifts Polyester Costs
On the same day, crude oil rallied over 2.7% after reports of a vessel attack near the Strait of Hormuz and the US termination of a general license for Iranian oil sanctions waivers. Higher oil prices directly raise the production cost of polyester, a key cotton substitute. When polyester becomes costlier, spinners tend to increase their cotton blending ratio, providing additional support to cotton prices.
This transmission channel had been subdued in recent months, but the strong correlation between the oil spike and the cotton surge on July 7 suggests that funds are reassessing the cost logic of synthetic substitution. For buyers, this means that focusing solely on cotton supply-demand dynamics is insufficient – crude oil trends have become an indispensable variable.
Positioning and Sentiment: Rebound Potential After Net Long Reduction
CFTC data showed that as of the week ending June 30, speculative net long positions in ICE cotton decreased by 3,740 contracts to 54,512. The continuous reduction in net longs typically indicates that market sentiment has cooled from overheated levels, creating room for a rebound. The July 7 surge was a combination of short covering and new buying triggered by weather and demand expectations, building on this positioning structure.
The market now focuses on three key reports: Thursday's export sales report, Friday's USDA global supply-demand estimates, and the delayed CFTC commitments of traders report. These will verify whether the rally has fundamental support from actual export demand, global balance sheets, and speculative positioning.
Spot Market Lagging
Compared with futures, the spot market was more restrained. The Cotlook A index stood at 87.30 cents/lb on July 7, up only 150 points (1.75%), far below the futures' 3.82% gain. The widening futures-spot spread indicates that downstream mills are reluctant to accept current high prices, with procurement limited to essential needs. If this pattern persists, it may attract hedging pressure, capping further upside.
