The crude oil market is experiencing a rare 'gap-inventory inversion': geopolitical conflict has created a real supply disruption, while demand weakness is already foreshadowed in inventory data. For the textile supply chain, this is not just a simple oil price fluctuation, but a signal that the cost pass-through chain for chemical fiber feedstocks is about to be repriced.
Supply Gap and Inventory Anomaly
Transit through the Strait of Hormuz has recovered to only 10%-15% of pre-conflict levels, with Middle East crude loadings falling from 20 million barrels per day in early July to 12 million bpd, creating a global supply gap of 8.3 million bpd. This figure far exceeds previous market expectations of a risk premium, meaning crude has shifted from a 'potential threat' to an 'actual shortage.' Brent crude opened near $89 per barrel, with gold and silver also surging, as risk-off sentiment and physical shortages resonated.
Meanwhile, U.S. commercial crude inventories rose by 17.423 million barrels in a single week, the largest gain in three and a half years, and the Strategic Petroleum Reserve fell below 300 million barrels. Rising inventories might seem to ease shortages, but they actually reflect lower refinery utilization and weakening demand—a classic 'passive build' that contrasts with geopolitical supply gaps. For textile companies, this contradiction implies more volatile raw material prices, not a one-way rally.
Pass-Through Logic for Chemical Fiber Costs
The transmission of crude oil prices to the textile supply chain is not synchronized. Polyester filament, nylon, and other chemical fiber products rely directly on naphtha and PX, whose price adjustments often lag crude by one to two weeks. In the short term, high oil prices will lift intermediate products like PTA and MEG, squeezing polyester plant margins; but if demand weakens in Q4 as expected, insufficient end-order volumes will cap fiber price increases, creating a tug-of-war between cost-push and demand drag.
For textile companies, this means procurement decisions can no longer simply follow oil prices. The current low-inventory environment supports oil prices from falling deeply, but the end of the U.S. summer driving season and lower refinery utilization in September-October are building demand-side headwinds. Once geopolitical premiums fade, oil prices will fall, dragging down chemical fiber feedstock prices rapidly, and companies with large inventories will face write-down losses.
Ripple Effects Across Industrial Clusters
Chemical fiber clusters in Keqiao, Shengze, and other regions will bear the brunt. Small and medium-sized weaving enterprises in these areas typically adopt a 'buy-as-needed' procurement model, making them highly sensitive to price swings. When oil prices are high, fiber producers tend to hold prices firm, but if downstream grey fabric orders do not recover, price increases cannot pass through, squeezing weavers' margins from both ends.
Meanwhile, export-oriented companies must watch currency and freight cost linkages. Geopolitical conflict boosts safe-haven assets, increasing RMB exchange rate volatility, and higher marine insurance premiums add to export costs. For textile orders denominated in U.S. dollars, exchange losses may offset some raw material cost advantages.
