The invisible supply chain link between oil and cotton tightened again on July 21. ICE cotton futures for December rose 1.5 cents to settle at 80.42 cents per pound, a gain of 1.9%. Two key drivers fueled the rally: a sharp increase in crude oil prices due to escalating Middle East geopolitical tensions, and a full premium sale on the first day of China's reserve cotton auction.
Oil Surge Reshapes the Cost Ratio Between Polyester and Cotton
West Texas Intermediate crude surged over 2% on the day, hitting its highest level in five weeks. Escalating attacks between the US and Iran, coupled with Houthi threats to impose a maritime blockade on Saudi Arabia, have intensified fears of energy supply disruptions in the Middle East. For the textile industry, the immediate impact of higher oil prices is a rise in chemical fiber costs—polyester, cotton's main substitute, becomes more expensive to produce, giving cotton a relative price advantage. Texworld research indicates that some weaving mills in the Jiangsu-Zhejiang region are already evaluating whether to shift some polyester orders toward cotton products, suggesting the substitution effect is beginning to transmit into actual procurement.
Premium Reserve Cotton Auction: A Convergence of Policy Floor and Market Sentiment
China National Cotton Reserves Corporation launched the 2026 reserve cotton sale on July 20, offering 8,006.078 metric tons on the first day. All lots were sold at premiums above the base price, achieving a 100% clearance rate. This outcome reflects the confluence of three factors: policy pricing below current import parity, genuine demand from mills with full order books, and bullish market sentiment amplified by the auction results themselves. As the world's largest cotton consumer and importer, China's procurement rhythm is increasingly acting as a price anchor for the global market.
India's Delayed Planting: Supply-Side Uncertainty Accumulates
While demand signals remain positive, supply-side risks are building. Monsoon rainfall in India has been persistently below normal, leaving cotton planting progress roughly 23% behind last year's pace. As a major cotton exporter, any shortfall in India's production could tighten the global supply-demand balance. StoneX senior analyst Valentin Olah noted that weather-related production concerns in India are providing additional support to ICE cotton prices.
Short-Term Bullish but Macro Risks Warrant Caution
In summary, the current ICE cotton market is in a 'bullish resonance' phase: rising oil supports the price ratio, China's reserve cotton premiums underscore demand resilience, and India's delayed planting threatens supply. Deliverable ICE stocks have declined to 97,800 bales from 98,838 bales, indicating reduced warehouse pressure. However, a rising US dollar index and persistent uncertainties around global tariff wars and the Middle East conflict call for caution. For domestic textile mills, current prices already reflect many positive expectations, and the risk of chasing highs is increasing.
