International cotton prices carved an independent path amid macro headwinds and industry tailwinds. On August 3, ICE December cotton futures closed up 0.78 cents to 82.57 cents/lb, a 0.95% gain, despite US crude falling over 5% and Brent tumbling about 7% intraday. The oil slump normally pressures cotton through polyester substitution, yet prices held firm—underpinned by export data and positioning.
Background
US cotton export sales surged last week. The USDA report for the week ended July 23 showed net sales of 352,400 bales for the next marketing year, nearly 22 times the prior week's 16,100 bales. This far exceeded expectations and became the core of bullish sentiment. Speculative net longs remained elevated, dipping only 2,295 contracts to 70,542 in the week ended July 28, still heavy. A StoneX risk advisor noted that fund traders hold substantial net longs and the weekly chart shows a mild uptrend.
Deliverable stocks at ICE fell to 87,606 bales as of July 31, down 3,093 from the previous session, indicating firm physical demand and limited delivery pressure. However, US crop conditions deteriorated: the good-to-excellent rating dropped to 42% for the week ending August 2, from 46% a week earlier and 55% a year ago. This raises concerns about future supply and may support deferred contracts.
Industry Impact
Oil's impact on cotton is not one-way. Lower oil reduces polyester production costs, potentially weakening cotton demand elasticity. But cotton showed resilience to this bearish factor, suggesting demand-side strength (export surge, low stocks) outweighed substitution effects. For textile mills, this means raw material costs will stay elevated in the short term, while polyester producers may gain a relative cost advantage. The cotton-polyester spread will directly influence downstream fiber blending decisions.
Geopolitics is another variable. Trump's decision to delay strikes on Iran raised hopes of increased Gulf oil supply, pushing crude to three-week lows. If a US-Iran deal materializes, lower oil prices could sustain polyester substitution pressure. Yet cotton's financial attributes (weaker dollar) and industrial fundamentals (strong exports) are offsetting, likely keeping prices in a high-level range.
For buyers, chasing prices at current levels is risky. ICE stocks near 87,600 bales indicate tight deliverable supply, but the crop deterioration may already be priced in. Watch weekly export sales and crop progress reports; if export momentum slows or ratings stabilize, a pullback window may open.
