Raw material costs are transmitting downstream along the supply chain, and the polyester yarn market is showing clear supply-demand signals. According to publicly available industry data as of July 9, the average raw material inventory of pure polyester yarn enterprises has risen to 7.11 days, an increase of 0.37 days from the previous week, representing a sequential growth of approximately 5.5%. This data point reflects simultaneous efforts from both the cost side and the demand side.
Cost-Driven Formation of a Price Floor
Upstream raw materials for polyester yarn—polyester staple fiber and PTA—have been trending gradually higher recently. Although the increases are modest, the persistent cost hikes are squeezing profit margins for polyester yarn producers. From an industry perspective, this type of gradual rise is often more transmissible than a sharp spike: downstream weaving mills are more receptive to phased price adjustments rather than a single large jump.
The support from the cost side is not an isolated event. Increased geopolitical instability has led some enterprises to worry about raw material supply stability, prompting them to stock up earlier. This precautionary purchasing behavior was particularly evident in the market in early July. The sequential increase in raw material inventory days directly reflects a shift in corporate mindset from 'buy-as-needed' to 'moderate stockpiling.'
Marginal Improvement in Demand: Short-Term Momentum from Restocking
The demand side has also shown positive changes. In-plant rigid restocking demand has been released, and market purchasing willingness has significantly increased. The raw material inventory cycle for pure polyester yarn enterprises extended from 6.74 days at the end of June to 7.11 days at the beginning of July, indicating that downstream weaving mills are actively increasing their inventories.
However, it should be noted that this round of restocking is more of a concentrated release of 'rigid demand' rather than an explosion in end-consumption. Historical experience shows that July is typically a traditional off-season for the textile industry, with orders mostly small-batch and urgent. The sustainability of the current restocking momentum depends on the landing of subsequent autumn and winter orders.
Price Trends: Spot Market Firm, Futures Following
Supported by both costs and demand, spot prices for polyester yarn are trending firm. Related futures contracts are also showing a relatively strong performance following the fundamentals. For buyers, the current price window means: if raw material costs continue to rise, polyester yarn prices still have room for further increases; but if end-user orders fall short of expectations, this restocking wave may quickly subside.
The multi-factor scoring system shows that the current fundamental score for polyester yarn is close to 1 (leaning bullish). The cost side, demand side, and macro uncertainties all point to positive factors, but the score is not extremely high, indicating that market divergence remains. Some traders believe that the current rally is more of a phased inventory replenishment cycle rather than a trend reversal.
