On the morning of July 1, spot prices for polyester staple fiber in Jiangsu saw a notable decline, with mainstream trading ranges falling to 7,150-7,250 yuan per ton, and some low-end lots touching 6,950 yuan. The drop of 55 yuan to 7,200 yuan reflects a convergence of upstream cost weakness and downstream demand contraction.
Cost-side Easing and Supply-side Divergence
The immediate trigger came from the upstream cost side. Restored navigation capacity in the strait improved global crude supply expectations, pushing international oil prices lower overnight and directly weakening cost support for polyester raw materials. Meanwhile, planned maintenance at polyester feedstock plants is gradually being implemented, which in theory should reduce supply and support prices. However, polyester producers themselves are simultaneously executing output cuts of equal or greater magnitude. This means the positive effect of feedstock maintenance is largely offset by downstream curtailments, leaving the chain without fresh momentum.
Supply-Demand Dynamics and Price Transmission
Staple fiber producers now face a dilemma. Feedstock maintenance should bring temporary supply tightness, but deeper cuts at polyester mills have weakened procurement demand for staple fiber. This misalignment leaves staple fiber prices with little effective support. Trader feedback indicates a quiet morning session, with actual transactions limited to small-lot urgent needs and virtually no speculative stocking.
The appearance of low-end quotes near 6,950 yuan is notable, as this level approaches the cash cost line for some producers. If prices fall further, smaller capacity may face loss-making shutdowns, triggering spontaneous supply-side adjustments. But for large integrated players, losses in staple fiber can be offset by profits from upstream PTA or polyester chips, so voluntary output cuts are unlikely in the near term.
Implications for Downstream Weaving and Foreign Trade
Polyester staple fiber is a key raw material for spinning and nonwovens, so its price decline directly reduces input costs for yarn mills. For weavers producing polyester-cotton blends or pure polyester yarns, current price levels offer a chance to lock in lower costs and improve Q3 gross margins. But caution is warranted: if end-demand for garment exports remains soft, finished yarn inventory pressure will limit the scale of raw material procurement.
From a foreign trade perspective, the ongoing destocking cycle in overseas markets and RMB exchange rate fluctuations continue to suppress new orders. While lower staple fiber prices improve the cost competitiveness of export products, overseas buyers often adopt a "buy on strength, not weakness" mentality, delaying orders in anticipation of even lower prices.
Outlook
In the short term, polyester staple fiber prices are likely to remain in a weak consolidation range. Upside is capped by demand contraction from polyester output cuts, while downside is supported by feedstock costs and cash costs of marginal producers. Key variables to watch: whether international oil prices stabilize, and when polyester output cuts bottom out. If oil prices continue falling, staple fiber may test 6,800 yuan; if oil stabilizes and downstream restocking begins, current levels could mark a temporary bottom.
