The price of Nylon FDY has traced a textbook 'box range' over the past year. According to industry public data, from July 2, 2025, to July 2, 2026, the benchmark price fluctuated between a low of 14,175 yuan/ton and a high of 19,950 yuan/ton, an amplitude of nearly 29%. One year later, the price has returned to 16,300 yuan/ton, exactly flat with the start of the period.
This 'back to square one' trajectory is no coincidence. It reveals a fragile balance between capacity expansion and demand contraction in the chemical fiber chain. For textile enterprises, understanding the industrial logic behind this price signal is more important than memorizing a single number.
The Price Range: Industrial Implications of Mid-Low Positioning
The current price of 16,300 yuan/ton sits in the mid-low range of the one-year price band. Relative to the median of 17,062.5 yuan/ton, the current price is about 4.5% below the median. More notably, the gap from the historic high of 19,950 yuan/ton is as large as 3,650 yuan, while the gap from the low of 14,175 yuan/ton is only 2,125 yuan. This suggests that while downside risk is limited, the momentum for an upward rebound is equally weak.
Looking at the annual average of 15,600.61 yuan/ton, the current price is slightly above average, indicating that the market is not in deep loss territory, but profit margins have been significantly compressed. For Nylon FDY producers, this is akin to walking a tightrope near the cost line—any fluctuation in raw material caprolactam could directly erode already thin processing margins.
Supply-Demand Transmission: The Squeezed Middle
The price stalemate in Nylon FDY reflects simultaneous pressure from both upstream and downstream. Upstream, caprolactam capacity continues to expand, with over one million tons of new domestic capacity added since 2025, leading to ample raw material supply and a downward shift in cost support. The weakening cost base has removed the 'engine' for Nylon FDY price increases.
Downstream, textile end-demand has not seen the expected strong recovery. Operating rates in major weaving clusters such as Shengze and Changxing remain around 70%, with gray fabric inventories destocking slowly. Fabric buyers prefer just-in-time purchasing rather than building safety stocks. This 'short and fast' procurement model directly suppresses the room for Nylon FDY price increases.
Notably, the annual price fluctuation included a low of 14,175 yuan/ton, which is about 8% below the industry average cost line, implying that some producers experienced periodic losses at that point. Such 'below-cost' pulse-like movements typically signal capacity consolidation, but the subsequent price rebound was limited, indicating that the overcapacity situation has not fundamentally changed.
Price Outlook: Box Pattern Hard to Break in Short Term
Looking ahead to the next six months, Nylon FDY will likely continue to trade in the 15,000-17,500 yuan/ton range. An upward breakout would require two conditions: an unexpected rise in caprolactam prices due to maintenance or production cuts, and a concentrated release of autumn/winter fabric orders. Based on current industry production schedules and terminal brand orders, neither condition appears likely in the short term.
Downside risks also exist. If international crude oil prices fall sharply, dragging down the benzene-caprolactam chain, Nylon FDY could retest the 15,000 yuan/ton level. However, for buyers, this represents an opportunity to build positions incrementally—the 14,175 yuan/ton low has already demonstrated the price floor for this category.
