On the afternoon of July 24, international crude oil markets experienced a sharp decline. Brent crude dropped 2% in less than half an hour to $93.02 per barrel, while WTI crude fell below the $91 threshold, approaching a 2% intraday decline. This oil price volatility signals a subtle but important shift in the cost support logic for the textile chemical fiber supply chain.
Cost Logic Weakens
Crude oil is the direct upstream feedstock for PTA and MEG, which are precursors to polyester. When Brent crude slides from the $95 range to $93, procurement costs for PX (paraxylene) will adjust downward, subsequently transmitting to PTA spot prices. Industry data shows the short-term correlation coefficient between PTA and crude oil is around 0.7—meaning for every 1% drop in oil, PTA costs fall by about 0.7%. Based on this calculation, the current decline is sufficient to create a 50-80 yuan/ton reduction in PTA prices.
Polyester filament and staple fiber, the most widely used chemical fiber categories in textiles, rely heavily on the weighted cost of PTA and MEG. This sharp oil drop will quickly narrow the immediate profit margins of polyester yarn factories. Given that downstream weaving mills generally maintain a low-inventory, 'just-in-time' purchasing strategy, this cost signal may trigger a wave of wait-and-see sentiment.
Industrial Cluster Reactions and Inventory Game
In polyester yarn clusters such as Shengze, Changxing, and Xiaoshan, some traders have suspended price quotations. Several polyester plants adjusted their daily ex-factory prices mid-afternoon by 50-100 yuan/ton to manage pricing risk from the sudden oil decline. This 'real-time price adjustment' behavior is uncommon in the recent range-bound market, reflecting heightened sensitivity to cost-side changes.
More notably, current polyester product inventories are at moderately high levels—POY inventory days are around 14-16, and FDY around 18-20. The oil price plunge will intensify downstream hesitancy, forcing plants to destock through concessions. For fabric buyers, the coming week may represent a rare bargaining window this year.
Foreign Trade and Exchange Rate Linkage
For export-oriented textile companies, oil price declines often coincide with a stronger US dollar. On July 24, the yuan's central parity rate against the dollar showed slight adjustment. If oil remains under pressure, exchange rate fluctuations could directly erode export order profits. Exporters are advised to closely monitor offshore yuan movements and hedge settlement costs via forward contracts when necessary.
Meanwhile, geopolitical factors in the Middle East have not fully dissipated. Brent crude has strong technical support around $93, and a short-term rebound is possible. Textile companies should avoid over-aggressive short-term raw material procurement and instead replenish inventory in batches across multiple cycles.
