On July 13, ICE cotton futures for December delivery settled at 81.51 cents per pound, down just 0.03 cent or 0.04% from the previous session. Behind this seemingly calm number lies a tug-of-war between two forces: the USDA's revised production estimate and extreme heat in key growing regions.
The Dual Game of Weather and Output
In its July WASDE report, USDA raised the 2026/27 US cotton output estimate by 400,000 bales to 13.7 million bales, while global ending stocks increased by 300,000 bales. This supply-side addition would normally pressure prices. However, the weekly crop progress report released almost simultaneously showed the US cotton good-to-excellent rate dropped to 44% for the week ending July 12, down from 46% the previous week and well below 54% a year ago.
West Texas, the most important cotton-growing region in the US, is experiencing sustained high temperatures. A Price Futures Group vice president noted that the hot weather across the Great Plains provided the main support for that day's cotton prices. This means that while USDA remains optimistic about total output, the market is repricing actual growing conditions. If the heat persists through the boll-setting period, the risk of lower yields will directly challenge the 13.7 million bale estimate.
Transmission Effects from External Variables
Escalating geopolitical tensions in the Middle East indirectly influenced cotton pricing through energy markets. Following the US announcement of a naval blockade on Iran, concerns over energy transit through the Strait of Hormuz surged, sending oil prices up 9% that day. Higher oil prices directly raise the production cost of polyester fiber, a major substitute for cotton. When polyester becomes more expensive, textile mills tend to favor natural fibers in their blend ratios, creating demand-side support for cotton.
Meanwhile, the US dollar index edged slightly higher. A stronger dollar theoretically makes US cotton less competitive for overseas buyers, but the market reaction was muted, indicating that trading focus remains on supply-side variables—weather and output revisions.
Signals from Stocks and Basis
ICE data showed that deliverable No. 2 cotton futures stocks stood at 127,127 bales as of July 10, down sharply from 158,607 bales the previous week. This rapid destocking suggests tight availability in the physical market, contrasting with the narrow range in futures and implying that industry funds are waiting for clearer directional cues. The Cotlook A index closed at 90.70 cents per pound on July 13, a premium of about 9 cents over futures, further confirming relative firmness in the spot market.
Industry Implications
For China's cotton-textile industry, the divergence between US output and quality rates means increased uncertainty in import costs. If the heat persists and leads to a US crop reduction, overseas prices may trigger a weather premium early, widening the gap between domestic and international prices. On the other hand, high oil prices are already transmitting to the chemical fiber sector, with polyester staple fiber quotes recently showing signs of following the uptrend, which will alter mills' raw material blending decisions.
Looking at downstream orders, the current period is the autumn/winter fabric preparation season, making the yarn market highly sensitive to cotton price fluctuations. If US cotton trends upward due to weather factors, domestic cotton yarn quotes will have to follow, squeezing the profit margins of weaving mills.
