On August 31, the most-active ICE cotton futures contract for December settled at 93.14 cents per pound, up 1.93% on the day and touching an intraday high of 93.74 cents—the strongest level since 2024. Over the entire month of August, the contract gained approximately 14%, marking a second consecutive monthly advance. The immediate catalyst was persistent hot and dry weather across key US growing regions, which has shifted market focus from demand fundamentals to supply-side weather premiums.
Market Drivers
The United States is a major cotton exporter, and adverse weather during the critical growing period directly undermines production expectations for the new season. The influence of a strong El Niño event has been repeatedly cited, with analysts in Kansas pointing to production uncertainty, weather impacts, and oil price trends as combined supports for prices. Notably, this rally is not isolated—international crude oil rose over 2% on the same day due to heightened tensions near the Strait of Hormuz, raising production costs for polyester fiber and indirectly strengthening cotton's competitiveness as a substitute.
Market sentiment has already been priced in ahead of the USDA's September 11 supply-demand report, with traders expecting a downward revision in US cotton output. Such expectations are not unfounded: if hot, dry conditions persist, both yields and harvested acreage could fall short of earlier projections. One analyst bluntly stated that cotton production will decline and prices will keep rising until no buyers remain—highlighting the core question: how certain is the supply contraction?
Industry Impact
For Chinese textile mills, a stronger offshore market means higher import costs and compressed spinning margins. The transmission mechanism works through two channels: mills directly purchasing imported cotton face higher raw material costs as ICE futures climb, and international price strength tends to lift sentiment in domestic Zhengzhou cotton futures, despite some cushioning from import quotas and price spreads. Overall, upward pressure on raw materials will gradually pass through to yarn and fabric stages.
Geopolitical factors add another layer of uncertainty. Higher oil prices not only raise costs for polyester substitutes but also increase shipping and logistics expenses for cotton. For foreign trade companies reliant on ocean freight, this translates to additional landed costs. On the other hand, a weaker US dollar provides some support for dollar-denominated cotton, but falling US equities reflect concerns about inflation and tighter monetary policy—if the macro environment deteriorates, end-consumer demand may weaken, capping further upside.
From a purchasing perspective, current prices are at multi-year highs, and chasing the rally carries elevated risk. Historical experience suggests that weather premiums often retrace after official reports are released. If the USDA report shows a smaller cut than expected, prices could correct quickly; conversely, if the crop loss is confirmed, the price center may shift higher. Therefore, firms must balance cost locking against risk avoidance.
