At the close of the morning session on August 5, cotton futures (2609) rose 1.33% to 16,020 points, and cotton yarn (2609) gained 1.10% to 22,515 points. In stark contrast, PTA (2609) fell 3.66% to 5,690 points, staple fiber (2609) dropped 3.47% to 7,168 points, and bottle chips (2609) plunged 4.93% to 7,024 points. On the same trading day, cotton and chemical fibers moved in opposite directions—a divergence driven by cost dynamics and supply-demand fundamentals.
Market Background
The uptick in cotton prices is primarily fueled by weather premiums in overseas markets and expectations of reduced planting areas. Domestic commercial cotton inventories are depleting faster than expected, and the tight supply before the new crop season supports bullish sentiment. Cotton yarn following the rise indicates that downstream weaving mills are somewhat accepting of higher cotton prices, at least for now. On the polyester side, the sharp declines in PTA and staple fiber, both exceeding 3%, and the nearly 5% drop in bottle chips are unusual in recent months.
The core driver behind the chemical fiber weakness is crude oil. International oil prices have been volatile and trending down, weakening PX cost support and compressing PTA processing margins. Meanwhile, polyester plants maintain high operating rates, but downstream textile and apparel orders are in a seasonal transition, leading to weak demand and rising inventories. With weak supply and demand, prices naturally face downward pressure.
Industry Impact
The cotton-chemical fiber divergence directly impacts the cost structure of textile enterprises. For blended yarn producers, cotton and polyester staple fiber are the two main raw materials. Higher cotton costs are partially offset by lower staple fiber prices, so the net cost change may not be as drastic as the futures market suggests. However, for pure cotton mills, raw material cost pressure is undoubtedly increasing.
From a chain perspective, cotton yarn rose but less than cotton, indicating that spinning margins are being squeezed. Weaving mills face limited ability to pass on higher yarn costs, especially for export orders priced on long-term contracts. Conversely, the drop in staple fiber provides relief for polyester-cotton blended fabric producers, allowing them to optimize raw material ratios by increasing chemical fiber content.
Capital flows also deserve attention. Amid macro uncertainties, funds tend to allocate to fundamentally stronger commodities. Cotton, with its supply narrative, attracts buying, while polyester chain is sold off due to weak crude. Such flows amplify short-term volatility, but long-term prices will revert to fundamentals.
Practical Recommendations
For Procurement Teams - Build cotton positions gradually, locking in lower-priced distant contracts on dips, avoiding chasing highs. - Monitor the price spread between polyester staple fiber and cotton; when it widens, adjust blending ratios to reduce overall costs. - For chemical raw materials like PTA and bottle chips, adopt a hand-to-mouth procurement strategy to avoid inventory losses from oil price fluctuations.
For Exporters - Include raw material price adjustment clauses in export quotations to protect margins from cotton price volatility. - Watch currency and oil trends; if oil remains low, chemical fiber products may gain export competitiveness, so explore related order categories. - Use futures for hedging, especially at high cotton prices; consider buying put options to hedge downside risks.
In summary, the August 5 market divergence reflects a repricing of costs and fundamentals. Textile companies should move beyond single-commodity thinking, review raw material portfolios from a chain-wide perspective, and adjust procurement and production strategies flexibly to safeguard profits in volatile markets.
