Oil prices breaking through the $100 mark, a level not seen since May, are reshaping the competitive landscape of textile raw materials through a subtle transmission chain. For the cotton market, crude oil is not only a measure of transportation costs but also directly determines the production cost of synthetic fibers—especially polyester staple fiber. When polyester becomes more expensive, cotton's relative cost advantage is activated, becoming the core support for ICE cotton futures to inch higher despite weak export data.
Background: Cotton Price Game Under Mixed Factors
On July 23, the most active ICE December cotton futures contract settled at 81.21 cents/lb, up a marginal 0.12%. This seemingly flat gain was achieved under multiple bearish pressures. The USDA's weekly export sales report for the week ending July 16 showed net sales of current-crop US upland cotton at only 51,287 bales, up 49% week-on-week but down 12% from the four-week average. Net sales to China were 15,475 bales, with zero for the next crop year. The industry interpreted this as a lack of sustained demand momentum.
However, bearish factors did not dominate. External markets provided key support: CBOT wheat hit a two-year high, soybeans and corn firmed, and crude oil returned to $100 driven by Red Sea geopolitical events. Price Futures Group Vice President Jack Scoville noted that the overall rally in agricultural markets and rising oil prices pushing up polyester costs formed the bottom support for cotton. This means the current pricing logic for cotton has shifted from pure supply-demand dynamics to a mode incorporating cross-commodity comparison and macro risk pricing.
Industry Impact: Polyester Substitution and Supply Contraction
The impact of rising oil prices on the cotton market is indirect, transmitted through the intermediate variable of substitute costs. When polyester production costs rise due to higher crude oil, textile mills naturally tilt towards cotton in raw material selection, increasing cotton's demand elasticity. This mechanism was clearly demonstrated in recent market reactions—cotton prices held the 81-cent level even as US export data weakened.
Meanwhile, supply-side signals from major cotton-producing countries are also tightening. India's cotton sowing pace has slowed due to weather issues, raising concerns about next season's output. Consultancy Agroconsult forecasts Brazil's 2025/26 cotton crop at 4.2 million tons, down 1.5% year-on-year, mainly due to reduced planted area. Pakistan, facing lower domestic production, has ordered approximately 206,000 bales from the US and is increasing purchases from Brazil, highlighting its growing reliance on imports. These supply-side variables are building a relatively solid floor for forward cotton prices.
Notably, ICE deliverable No. 2 cotton futures contract stocks remained unchanged at 94,235 bales, indicating no significant increase in delivery pressure in the spot market, which eases concerns about near-term oversupply.
