The U.S. cotton belt is undergoing a severe heat test. On July 13, the ICE December cotton contract settled at 81.51 cents per pound, down 0.03 cents, but the market is caught between two opposing forces: deteriorating crop conditions and a USDA-increased production forecast.
Weather and Geopolitics: Two Pillars of Support
The latest Crop Progress report shows the U.S. cotton good-to-excellent rating fell for a second consecutive week to 44% as of July 12, down from 46% the prior week and a full 10 percentage points below last year's 54%. Persistent heat and dryness in West Texas and the broader Great Plains are impacting the critical boll development stage. A Price Futures Group analyst noted that the hot weather was the primary support for cotton prices that day.
Simultaneously, geopolitical tensions in the Middle East escalated sharply. The U.S.-Iran military conflict drove oil prices up 9% in a single session, hitting a one-month high. Higher oil prices directly raise polyester production costs, enhancing cotton's price competitiveness as a textile raw material. This substitution effect provides an additional floor for cotton prices. The U.S. dollar index edged higher but was seen as having a limited dampening effect on cotton.
USDA Report: Supply-Side Pressure Remains
Despite the bullish weather factor, the fundamental supply-demand picture is not tightening. The USDA's July WASDE report raised the 2026/27 U.S. cotton production estimate by 400,000 bales to 13.7 million bales, and global ending stocks were increased by 300,000 bales. This data implies ample global supply for the new season, offsetting some of the weather premium.
ICE deliverable stocks data also reflects a well-supplied spot market. As of July 10, stocks stood at 127,127 bales, down from 158,607 bales the previous week but still at elevated historical levels, indicating no shortage.
Transmission and Impact on the Supply Chain
This tug-of-war between weather bullishness and supply-demand bearishness presents a challenge for downstream mills' procurement decisions. With prices hovering around 81 cents without a clear directional breakout, inventory management becomes critical. Betting heavily on a weather-driven rally risks a price correction if USDA data further pressures the market. Conversely, maintaining low inventories exposes buyers to potential price spikes from sudden weather events.
The Cotlook A Index rose 95 points to 90.70 cents per pound, reflecting firm demand for high-quality cotton in the international spot market. The spread between domestic and international prices will also influence import purchasing rhythms.
Outlook: Focus on Rainfall and Geopolitical Evolution
In the near term, rainfall forecasts for the key U.S. growing regions over the next two weeks will be the pivotal variable. Continued heat could further erode the good-to-excellent rating, potentially igniting a new round of weather speculation. Meanwhile, developments in the Middle East will directly impact oil prices and, through the polyester substitution channel, indirectly affect cotton. Over the medium to long term, how the market digests the USDA's higher production estimate and the actual quality of the new crop will determine the price range.
