Cotton Prices Hover High: Oil Slump Reshapes Fiber Substitution Logic, Exporters Warned of Basis Risk

On August 3, ICE December cotton futures settled 0.78 cents higher at 82.57 cents/lb, up 0.95%, yet the gains masked intraday pressure from a sharp oil slump. US crude fell over 5%, while Brent plunged nearly 7% to a three-week low, directly lowering production costs for polyester, cotton's main substitute, casting a shadow over cotton prices.

Background

CFTC data released last Friday (July 31) showed that for the week ending July 28, speculators trimmed net long positions in ICE cotton by 2,295 lots to 70,542 lots. Despite the reduction, StoneX risk management adviser Bailey McHenry noted that fund traders still hold considerably heavy net longs, and on a weekly basis the market remains in a slight uptrend. This assessment aligns with the tape: despite profit-taking and oil drag, futures managed to close higher.

Meanwhile, USDA's latest crop progress report showed that as of August 2, US cotton condition ratings fell to 42% good-to-excellent, down from 46% the prior week and 55% a year ago. The consecutive decline signals potential quality concerns for the new crop, providing some support to deferred contracts. Additionally, ICE deliverable No. 2 cotton stocks fell to 87,606 bales, down 3,093 from the prior session, indicating steady physical demand.

Industry Impact

The oil price slump transmits through the textile chain non-linearly. Polyester, a major cotton substitute, has production costs highly correlated with crude. When oil prices plunge, polyester prices weaken, prompting some orders to shift from cotton to man-made fibers, thereby capping cotton's upside. This explains why futures were under pressure for most of the session—despite strong export data, the market weighed substitution effects.

Notably, USDA's export sales report for the week ending July 23 showed net new-crop upland cotton sales of 352,400 bales, sharply higher than 16,100 bales the prior week. This surge indicates robust demand for US cotton amid global supply chain restructuring. However, exporters should be cautious: if oil stays low, polyester's price advantage may widen, causing some orders to switch at the last minute, affecting actual fulfillment.

For domestic textile mills, ICE cotton fluctuations directly impact imported cotton costs. With deteriorating crop conditions and speculative de-risking, market divergence is widening, and prices may remain rangebound with high volatility. Buyers locking in raw materials at current levels should guard against pullback risks, while foreign trade firms must factor in currency and basis changes when signing forward contracts.

Practical Recommendations

For Buyers - Monitor weekly US crop condition data; if good-to-excellent falls below 40%, consider increasing inventory to hedge against production shortfalls. - Use ICE pullbacks to build deferred basis positions in tranches, avoiding chasing highs. - Compare cotton-polyester spreads; if the gap widens to historical highs, consider partial substitution to reduce costs.

For Exporters - Use floating basis pricing in export contracts and pair with forward currency hedging to mitigate FX risks. - Track US-Iran tensions and OPEC+ output policies; every 10% drop in oil reduces polyester costs by 3%-5%, so adjust quotes promptly. - Leverage weekly USDA export sales data to anticipate shipping schedules and arrange logistics to avoid default penalties from delays.
