On August 31, ICE December cotton futures settled at 93.14 cents/lb, hitting a two-year high of 93.74 cents/lb intraday, up 1.93% on the day and about 14% for the month. The rally was not driven by a single factor but by a rare confluence of persistent heat and drought in key US growing areas and rising oil prices from Middle East geopolitical tensions, creating a dual resonance on the supply side and cost side. For the textile industry chain, this is not just a digital move on the futures board; it means a substantial increase in raw material procurement costs and a redistribution of downstream profit margins.
Supply Contraction Expectations: Weather as the Core Pricing Variable
Extreme heat and low rainfall since June in US cotton-growing regions have significantly affected new-crop yield prospects. Market expectations for a production cut in the USDA supply-demand report due September 11 are intensifying, with analysts widely believing that hot, dry weather in key production areas will lead to lower output. These expectations have been steadily lifting futures prices in recent weeks, and the second consecutive monthly gain in August confirms that funds are pricing in supply tightness. Notably, the strength of the El Niño event has been repeatedly cited, and its evolution will continue to influence weather during the critical growing period, meaning the supply narrative is not over and price volatility may remain elevated.
Oil Price Linkage: Substitute Cost Reshapes Parity
Concurrently, US military action against an Iranian island and Iran's response pushed crude oil prices up more than 2.5% in a single day. Higher oil prices directly raise production costs for polyester fiber, allowing cotton's cost competitiveness against man-made fibers to be maintained or even expanded. In textile raw material selection, the price spread between cotton and polyester is a key parameter affecting spinners' blending ratios. When oil prices are high, polyester costs rise, making cotton relatively more attractive, which to some extent supports the downside of cotton prices. However, sustained strength in oil prices could also fuel inflation expectations, influencing global monetary policy direction and potentially suppressing end-user demand—this is the other side of the risk in the cotton rally.
Industry Impact: Transmission from Futures to Physical Market
The strong futures performance has not yet fully transmitted to the physical market; on August 31, the Cotlook A index was suspended due to the UK summer bank holiday, offering a brief observation window. But it is foreseeable that if production cut expectations are confirmed in the USDA report, spot quotes will likely follow higher, affecting procurement costs for the new season. For textile enterprises, raw material costs typically account for 60%-70% of total costs; every one-cent-per-pound rise in cotton prices equates to an additional cost of about $22 per ton of lint, directly squeezing spinning margins. Meanwhile, geopolitical uncertainties also increase delivery risks for foreign trade orders, especially for logistics involving Middle East and European routes.
