At 88.22 cents per pound, the ICE December cotton contract settled 1.08% higher on September 10. Yet the real driver was not cotton itself but crude oil, which surged more than 6% the same day and reclaimed the $100-per-barrel mark. As oil lifts polyester feedstock costs, cotton's relative competitiveness improves, forming the most direct logic behind this rally.
Background
The oil spike was triggered by a sharp deterioration in Middle East shipping security. Since the outbreak of Iran-related tensions, attacks on shipping have increased by the largest margin, raising fears that already tight energy supplies could be further disrupted. Both benchmark crudes broke above $100, directly pushing up polyester raw material costs.
For textiles, this transmission path is familiar: crude oil to PTA to polyester chip to polyester staple fiber. Each step higher erodes synthetic fiber's substitution advantage over cotton. When polyester staple prices approach or exceed cotton, spinners typically raise the cotton ratio in their blends, providing demand-side support for cotton prices.
Meanwhile, the U.S. dollar strengthened on Thursday, recovering part of its earlier weekly losses. Since international cotton is priced in dollars, a stronger greenback makes it more expensive for buyers holding other currencies, capping cotton's upside.
Industry Impact
The variable drawing the most attention is the USDA's September World Agricultural Supply and Demand Estimates, due at midnight Beijing time on September 12. This report will offer the first relatively complete picture of how summer heat and drought affected U.S. Midwest crops.
From an industrial-belt perspective, weather premiums in U.S. cotton regions are already reflected in futures. If the report confirms a larger-than-expected production cut, ICE cotton could test higher resistance. Conversely, if the downgrade falls short of market expectations, the accumulated weather premium faces a correction.
The spot market strengthened in tandem. The Cotlook A index stood at 97.20 cents/lb on September 10, up 110 points, with international spot quotes following futures higher, suggesting the trade is forming expectations of near-term supply tightness.
Inventory data also flashed bullish signals. ICE reported that deliverable No. 2 cotton stocks fell to 50,415 bales as of September 9, down from 54,414 bales the previous session. Shrinking deliverable stocks typically imply some squeeze risk for nearby contracts, supporting front-month prices.
However, macro headwinds have not dissipated. U.S. stocks closed lower on Thursday, with August producer price data and surging oil raising concerns about a Federal Reserve rate hike next week. Rising Treasury yields eroded the appeal of risk assets. Rate hike expectations generally weigh on commodities, and cotton is unlikely to be immune.
Practical Advice
For China's textile supply chain, cotton is at a sensitive juncture where bullish and bearish factors intertwine. Oil strength and weather premiums provide upward momentum, while dollar strength and rate hike expectations cap the top. Volatility is likely to expand around the USDA report.
