Import cotton prices at Chinese main ports edged down on July 9, a seemingly modest shift that is sending ripples through the supply chain—from futures markets to spot trade and downstream yarn sectors—amplifying bearish signals at each stage.
Futures and Spot Markets Weaken in Tandem
On July 9, the International Cotton Price Index (SM) stood at 90.92 cents per pound, down 0.61 cents from the previous day, while the M-grade index fell 0.60 cents to 88.99 cents per pound. Converted at a 1% tariff rate and the Bank of China's central parity rate, the port delivery price for SM-grade cotton was approximately 15,226 yuan per ton, and for M-grade around 14,907 yuan per ton. The lower import cost directly undermines support for domestic spot cotton prices.
Meanwhile, the main contract for cotton on the Zhengzhou Commodity Exchange (ZCE) closed at 15,930 yuan per ton, down 245 yuan, or 1.52%, from the previous session. More notably, open interest fell by 34,680 lots, indicating that bullish capital is actively exiting, reflecting a pessimistic outlook for short-term price trends. The synchronized decline in both futures and spot markets suggests that the price drop is driven by broader market sentiment rather than a single factor.
Cost Transmission and Substitution Effects Compound
The decline in import cotton prices directly narrows the spread between imported and domestic cotton. For textile mills, the improved cost-effectiveness of imported cotton may shift some procurement demand toward foreign supplies, exerting substitution pressure on domestic lint cotton. This substitution effect is particularly pronounced in the current weak demand environment, further weighing on domestic lint prices.
From a supply chain transmission perspective, the softening of cotton prices cascades downstream. Lint, as an intermediate product, sees its cost support weaken, leading processors to become more cautious in purchasing. While the yarn segment reacts with a lag, the easing of upstream raw material costs has already created a slight bearish impact on yarn production costs. Raw materials account for over 60% of total yarn costs, so any fluctuation in cotton prices is amplified downstream.
Immediate Reactions in Industrial Clusters and Trade
As the distribution hub for imported cotton, price changes at Chinese main ports directly influence procurement decisions in coastal textile clusters, such as Shandong, Jiangsu, and Zhejiang provinces. Textile mills in these major consuming regions typically use main port quotes as benchmarks for import purchases. Following the price drop, some mills may adopt a wait-and-see approach, further dampening near-term transaction volumes.
For domestic cotton-growing regions, lower import prices intensify competition. Xinjiang cotton, as the main domestic variety, faces challenges to its price anchoring role. If import prices continue to weaken, sales of Xinjiang cotton may slow, increasing inventory pressure.
