Raw Material Market at Golden September Start: Futures-Spot Divergence and Cost-Driven Chain Divergence

In early September 2026, the textile raw material market entered its traditional 'Golden September' window, yet performance varied sharply across categories. Zhengzhou cotton futures settled at 17,110 CNY/ton, up 50 CNY from the previous day, while the domestic 3128B cotton spot index fell 53 CNY to 18,357 CNY/ton—widening the futures-spot spread to 1,247 CNY. This divergence signals market disagreement: futures are supported by tight supply expectations before new cotton arrives, while spot prices suffer from sluggish transactions. Meanwhile, polyester staple fiber stood out, surging 200 CNY to 8,080 CNY/ton, far outpacing cotton-related products.

Market Divergence: Futures-Spot Split and Product Strength

The cotton market's futures-spot divergence is not accidental. Futures are buoyed by expectations of tight supply before new cotton arrives—some Xinjiang ginners have already started pre-purchasing seed cotton, raising attention on new-season output and acquisition costs. On the spot side, however, spinners are cautious, old cotton consumption is slow, and transactions remain light. This 'hot futures, cold spot' pattern reflects a disconnect between speculative capital and physical demand—futures price expectations, while spot anchors to actual buying. For spinners, this means locking prices based on futures requires caution, as once new cotton floods the market, supply pressure may drag futures lower, with spot prices at risk of following.

Cotton yarn shows 'firm prices, divergent orders.' Futures rose slightly, and spot quotes moved up, but the recovery is limited—the anticipated bulk orders for the peak season have not materialized; trades are mostly small and short-term. Structurally, medium-to-high count compact yarns sell well, while low-count yarns face pressure, with finished goods inventories accumulating. This divergence stems from limited recovery in downstream fabric mill operating rates and high grey fabric inventories, indicating that end demand has not fully rebounded. In procurement, small spinners stick to hand-to-mouth buying to avoid price risks; large and mid-sized spinners replenish moderately, using post-pricing models to lock costs, reflecting differing views on the future.

Polyester staple fiber's rally is primarily cost-driven. Stronger upstream PTA and MEG prices, coupled with maintenance at some chemical fiber plants and active production cuts to support prices, tightened spot supply. However, demand has not kept pace—downstream fabric mills are buying only for immediate needs, with no signs of stockpiling. This suggests the rally lacks demand support and is more a result of cost pass-through and supply contraction. If upstream feedstocks fall or maintenance plants restart, added supply could pressure prices, making sustainability questionable.

Industry Impact: Cost Pass-Through and Demand Validation

The current chain shows a 'strong raw materials, weak demand' pattern. Cost support gives raw materials resilience, but weak end-demand recovery leads to divergence across categories. For upstream suppliers, cost-driven price hikes may improve margins short-term, but if downstream refuses to accept, increases won't last—polyester staple fiber is a case in point: prices surged on costs, but fabric mills bought only for immediate needs, showing limited acceptance of high prices. For midstream spinners, greater raw material volatility raises inventory management risks—cotton's futures-spot divergence, cotton yarn's order split, and staple fiber's cost-driven rally all require more precise procurement timing.

The cotton market's focus is new cotton arrival. As northern Xinjiang harvest approaches, concentrated supply will pressure the market, limiting Zhengzhou cotton's upside; prices will likely fluctuate without a strong unilateral rally. Cotton yarn's further gains depend on sustained terminal orders—if autumn/winter orders materialize, medium-to-high count yarns may continue to perform well, but low-count inventory pressure could drag overall prices. Polyester staple fiber remains highly linked to upstream petrochemicals; if PTA and MEG fall, it loses cost support, and without demand improvement, downside risks increase.

Practical Recommendations

For Buyers - Stick to need-based procurement and batch replenishment; avoid chasing highs amid futures-spot divergence, especially watch for price dips after new cotton arrives. - Use post-pricing models to lock costs and hedge against volatility, suitable for price-sensitive spinners. - Monitor downstream order changes closely—if autumn/winter orders pick up, moderately increase purchases of medium-to-high count yarns; if orders stay flat, maintain low inventory operations.

For Foreign Trade Companies - Watch the interplay of exchange rates and raw material prices; when raw materials are high, leave room in quotes to avoid margin erosion. - Differentiate strategies by product: for cotton yarn exports, focus on medium-to-high count items; for polyester staple fiber-related products, be alert to price adjustments from cost declines. - Use futures tools for hedging to lock forward procurement costs, especially during the uncertain period before new cotton arrives.
