ICE cotton futures for December settled at 78.30 cents per pound on July 6, up 1.53% day-on-day, driven by persistent heat and drought in key US growing regions and a delayed Indian monsoon. The US cotton good-to-excellent rating fell 2 percentage points week-on-week to 46%, below last year's level. Analysts suggest weather risk premiums are being re-priced into cotton, potentially pressuring downstream textile mills that have maintained a wait-and-see inventory strategy.
Weather Premium Is Being Repriced
The latest USDA crop progress report shows the US cotton good-to-excellent rate dropped to 46% for the week ending July 5, down 2 percentage points from the previous week and below 52% a year ago. While squaring and boll-setting rates are near the five-year average, the faster development pace combined with heat and drought raises uncertainty about final yields.
More notably, a 'heat dome' high-pressure system spread from the Midwest to the East last week, trapping hot air over the region. This weather pattern, occurring during the cotton flowering and boll-setting period, can cause shed and fiber development damage. Weekend rains in the southern US were scattered and insufficient to alleviate soil moisture deficits.
Meanwhile, India's meteorological department reported that June was the fifth driest on record since 1901. The monsoon is progressing slowly, and July rainfall is likely to be below average, threatening cotton planting and early growth. India, the world's second-largest cotton producer, could significantly impact global prices if output falters.
Grain Market Linkage Amplifies Cotton Volatility
CBOT soybean and corn futures both rose over 3% on July 6, driven by Midwest crop weather concerns and improved demand expectations. The substitution and capital allocation linkage between grains and cotton provided emotional support for cotton prices. Additionally, oil prices stabilized near pre-Iran-conflict levels, and the dollar index edged up, with external markets not exerting significant pressure on cotton.
From a positioning perspective, speculative short sentiment has eased. As weather risks persist, short covering could further push prices higher in the near term. However, the current ICE December contract price remains below the Cotlook A index (85.80 cents/lb), indicating relatively firm spot market conditions and room for convergence.
Implications for Downstream Procurement
For Chinese textile mills, the current 78 cents/lb level is above the cost basis established during May-June restocking. If weather premiums continue to accumulate, prices may break above 80 cents/lb, significantly raising procurement costs.
Industry feedback suggests that while mill operating rates have remained stable since late June, raw material inventories are generally low, with most mills adopting a hand-to-mouth buying strategy. This low-inventory approach reduces capital tie-up during stable periods but leaves mills vulnerable during rapid price increases. If the US cotton good-to-excellent rate continues to decline over the next two weeks, some mills may be forced to restock at higher prices.
