At the midday close on July 7, domestic futures markets exhibited a significant structural divergence: the polyester chain was entirely in the green, while the cotton spinning sector saw a rare divergence between cotton and cotton yarn. Behind this pattern lies a renewed tussle among three forces: cost transmission, inventory cycles, and end-demand.
Polyester Chain: Cost-Driven Rally with Supply Tightening
The PTA main contract rose 1.24% to 5536 points, staple fiber strengthened to 6944 points, and bottle-grade chips posted the largest gain of 1.52% to 6692 points. The core driver for the collective rally came from upstream: sustained firmness in PX prices supported by recent crude oil rebounds, coupled with temporary supply tightening due to maintenance at some PTA units, created a resonance between cost and supply.
For the textile industry, the rise in staple fiber—an intermediate polyester product—directly increases production costs for downstream nonwovens, filling materials, and certain blended fabrics. This means buyers using staple fiber as raw material may face supplier price increases or shortened payment terms in the next two weeks.
Cotton Spinning Divergence: Stagnant Raw Materials vs. Destocking Pressure
The cotton main contract edged up 0.21% to 16330 points, while cotton yarn fell 0.46% to 22675 points. This divergence is often viewed in futures markets as a leading indicator of weak downstream demand—raw material prices are unable to rise, yet finished product prices are falling, indicating that the profit margin in the spinning segment is being squeezed from both sides.
From an industry logic perspective, cotton currently benefits from weather premium during the new crop planting and growth period, providing price floor support. However, the downstream of cotton yarn—weaving and apparel enterprises—is generally facing a new normal of "small orders, short lead times" from overseas buyers, with cautious replenishment intentions. The weakness in cotton yarn futures is essentially a direct projection of insufficient terminal consumer confidence onto the intermediate link.
Cross-Category Transmission: Procurement Strategies Must Be Chain-Specific
Although both are textile raw materials, the polyester and cotton spinning chains are performing sharply differently in early July, meaning buyers can no longer formulate strategies under the blanket label of "textile raw materials." Polyester varieties are more influenced by crude oil and chemical plant operations, with high price elasticity and rapid fluctuation rhythms; cotton spinning varieties depend more on terminal consumption data and the global cotton supply-demand balance sheet.
For enterprises with mixed raw material needs, the current phase suggests adopting a "procure-on-demand, small-batch high-frequency" strategy for polyester raw materials, avoiding chasing prices during rapid rallies. For cotton and cotton yarn, companies can take advantage of basis opportunities in the futures market, locking in forward processing costs when cotton yarn prices are weak.
