A rebound in crude oil futures triggered a chain reaction far exceeding expectations in the polyester industry chain. On July 8, the average sales-to-production ratio of polyester filament yarn sample enterprises hit 103.6%, a sharp increase of 60.7 percentage points from the previous trading day. This figure means that downstream weaving mills purchased enough yarn to not only absorb the day’s output but also draw down some finished inventory. Yet a closer look at individual enterprise data—ranging from 10% to 300%—reveals not a broad rally but a deeply fragmented market game.
Cost Pulse and Sentiment Inflection
The direct trigger for this sales spike was the consecutive strengthening of crude oil and polyester raw material prices on July 7–8. For weaving mills that had been in cautious wait-and-see mode, the marginal rise in raw material costs broke the “waiting for a drop” psychology, creating a window for concentrated replenishment. From an industrial transmission perspective, rising PTA and MEG prices—driven by crude oil—lifted the cost floor of polyester filament yarn, prompting downstream buyers to accelerate orders before costs climbed further.
Importantly, the magnitude of the sales-to-production surge is disproportionate to the crude oil gain. The 103.6% ratio reflects more of a sentiment-driven “front-running” than a genuine recovery in demand. The fact that some enterprises reported ratios as low as 10% to 40% indicates that a significant portion of weaving mills remain skeptical about the rally’s durability and choose to stay on the sidelines. This polarization suggests that consensus on the near-term outlook has yet to form across the chain.
Divergence Behind High and Low Data
The distribution of sample data shows a typical “bimodal” pattern: one cluster at extreme highs of 200%–300%, and another densely packed in the 40%–80% range. This divergence correlates with the market structure of different industrial clusters. Conventional water-jet loom hubs like Shengze and Changxing, with lower greige fabric inventory pressure, are more sensitive to raw material price hikes and acted more decisively. In contrast, weaving bases focused on differentiated products, with longer order cycles, showed a lagged response to short-term price moves.
Furthermore, pricing strategy differences between large polyester plants and small-to-medium enterprises amplified the data dispersion. Some leading mills leveraged cost advantages to proactively lower prices and boost volume, while smaller players mostly followed market quotes, resulting in sharply different order-taking heat at the same time. While such divergence is not uncommon in past sales cycles, a single-day swing of 60.7 percentage points remains an extreme case in recent years.
Can the Rally Hold?
For buyers, the core question is whether this sales burst is a temporary release of pent-up demand or the start of a new uptrend. Historical patterns show that after a single-day sales-to-production ratio exceeds 100%, it typically retreats to the 80%–100% range over the next 3–5 trading days—unless crude oil sustains its upward momentum. Currently, the international crude market is influenced by both geopolitical factors and OPEC+ production policy, resulting in high short-term volatility without a clear trend breakout.
From the polyester segment’s own perspective, social inventories of polyester filament yarn remain at medium-to-high levels, and the supply-demand fundamentals do not support a sustained unilateral price rise. This sales surge is more a horizontal transfer of inventory from polyester plants to weaving mills than a vertical digestion driven by end-apparel orders. Once crude oil’s rally loses steam, downstream replenishment will quickly fade, and prices may revert to a range-bound pattern.
