On August 28, the benchmark price of viscose staple fiber (VSF) 1.2D settled at 14,400 CNY/ton, setting a new one-year high. Since the low of 12,800 CNY/ton, the market has recovered by 12.5%. This price movement signals that upstream cost pressures are transmitting down the textile supply chain, squeezing profit margins for yarn spinners and fabric mills.
High-Price Operation: Dual Support from Cost and Demand
Annual data from August 2025 to August 2026 shows the median price at 13,600 CNY/ton, with the current price 5.9% above that. The two-year and three-year overbought warnings indicate this rally is not a short-term fluctuation but has medium-term characteristics. Two main drivers: firm dissolving pulp prices, which squeeze VSF margins and prompt mills to hold prices, and stable orders for rayon yarn, especially early stocking for autumn/winter fabrics.
The daily increase of 0.42% may seem modest, but combined with a cumulative 1.41% rise since the start of the month, the market is on a steady upward trajectory. Such gradual increases are often more sustainable than sharp spikes, but they also mean limited room for correction if demand weakens. With the current price at the top of the annual range, further upside requires new catalysts; otherwise, the market will likely consolidate at high levels.
Supply Chain Transmission: Spinners Under Pressure, Fabric Mills Wait
As the main raw material for rayon yarn, VSF price changes directly affect spinners' cost structures. At 14,400 CNY/ton, theoretical costs have risen significantly from early 2025, while yarn prices lag. This compresses spinners' margins, prompting some small and medium enterprises to reduce output or switch to blended yarns. For fabric buyers, gray fabric prices have not fully adjusted yet, creating a temporary cost buffer, but if VSF prices stay high, fabric price hikes will likely emerge in the next one to two months.
Regional industrial clusters in Shandong and Jiangsu are major VSF consumers. Their mill operating rates serve as leading indicators of real demand. If operating rates remain above 70%, demand support is intact; below 65%, inventory accumulation and price cuts may follow. Additionally, substitution effects with Xinjiang cotton matter: if cotton prices weaken, some orders may shift to pure cotton, dampening VSF demand.
Future Outlook: High-Level Fluctuation, Risks and Opportunities
Based on fundamentals, VSF prices will likely fluctuate in a high range of 14,000-14,500 CNY/ton in the short term. Upside resistance comes from downstream resistance to high-priced raw materials and new capacity releases; downside support is provided by the cost line around 13,500-13,800 CNY/ton. For foreign trade companies, RMB exchange rate fluctuations and overseas demand recovery will indirectly affect export competitiveness of VSF products, so monitoring order rebounds from Southeast Asia is crucial.
Notably, the current price has exceeded the two-year overbought level, and historical patterns suggest a potential deep correction. Therefore, chasing high prices for stockpiling is not recommended. Instead, use futures hedging or forward contracts to lock in costs. Also, watch dissolving pulp price trends and major producers' maintenance plans, as these variables could break the current balance.
