Cotton Yarn 21S Price Hovers Near High: Narrowing Volatility Signals Intensifying Inventory Game

In mid-July, the benchmark price of cotton yarn 21S settled at 23,333.33 RMB/ton, down 0.28% from the start of the month, but the annual price center has shifted upward to 22,457.83 RMB/ton, with the current level 3.9% above the average. Behind these seemingly tame month-on-month figures lies a narrowing fluctuation range and a price curve that is increasingly rigid along the supply chain.

The Logic Behind the High-Level Stalemate

Looking at the full-year trajectory, cotton yarn 21S has traded within a range of 21,866.67 to 23,466.67 RMB/ton, a spread of only 1,600 RMB, implying an amplitude of about 7.3%—significantly lower than the 15%+ swings seen in previous years. This pattern of "narrow-range high-level volatility" essentially reflects a fierce inventory and margin tug-of-war between upstream and downstream. On the upstream side, raw cotton prices are supported by import quotas and state reserve release policies, creating rigid cost support. Downstream, weaving and garment enterprises, facing a tepid recovery in final orders, have limited acceptance of high-priced yarns and tend to buy hand-to-mouth.

The current price is only 133.34 RMB/ton below the annual high but 1,466.66 RMB/ton above the low, indicating that the center of gravity has clearly shifted upward, but momentum for further upside is fading. Industry data shows that cotton yarn 21S has been in a "high" position for most of the past year, meaning prices have mostly run above the average. While this has generated substantial spot profits for spinning mills, it also raises the risk of inventory buildup.

Transmission Along the Industrial Belt: Inventory Shifts Downstream

Customs data and industrial surveys corroborate each other: in the first half of the year, cotton yarn imports fell about 12% year-on-year, while yarn inventories in major cotton-producing regions such as Shandong, Henan, and Jiangsu increased by 15%-20%. This divergence suggests that domestic spinners have actively reduced imports and increased self-production in an attempt to convert raw material price margins into finished goods inventories, but end-user absorption has not kept pace.

Fabric distributors in the Keqiao Light Textile City and Nantong Home Textile Market report that July orders have weakened compared to May-June, with some weaving mills starting to reduce operating rates and extending yarn procurement cycles to 10-15 days. This implies that if the autumn/winter fabric stocking season in August-September fails to materialize as expected, spinners' inventory pressure may further shift to the weaving stage, raising the risk of a price correction from current highs.

Practical Recommendations

For Buyers - Current prices are at an annual high; recommend purchasing on a need-to basis and avoiding concentrated restocking. Monitor the August reserve cotton release policy—if volumes increase, it may trigger a short-term price pullback. - Sign monthly floating-price contracts with spinners to lock in basis spreads, taking advantage of the current narrow range to reduce unilateral volatility risk.

For Mills - Control finished yarn inventory levels and be alert to the risk of price declines if the peak season disappoints. Consider increasing the proportion of blended or differentiated yarns to diversify exposure to single-variety price swings. - Pay attention to the pace of sliding-scale cotton import quota issuance. If raw material costs soften, prioritize destocking high-priced inventories rather than chasing further purchases.
