When Brent crude approached $89 per barrel within the first half hour of trading, most textile professionals were thinking not of gas stations but of the cost line of PTA units. With the Strait of Hormuz operating at only 10%-15% of pre-conflict levels and Middle East crude loadings down from 20 million to 12 million barrels per day, the 8.3 million barrel daily supply gap has transformed from a market risk premium into a real logistics bottleneck. For the petrochemical-based textile chain, this is not a simple futures fluctuation but a stress test of cost transmission mechanisms.
Event Background
The Strait of Hormuz carries about one-third of global seaborne crude trade, and its disruption has directly altered the oil supply-demand balance. Iran's military has explicitly banned US forces from the Persian Gulf, Gulf of Oman, and the Strait of Hormuz, backed by a bounty policy, escalating US-Iran tensions. Meanwhile, Russia and Ukraine continue to strike each other's energy and transport infrastructure, amplifying supply-side uncertainty. These geopolitical risks pushed gold to $4,383.44 per ounce and silver to $65.13 per ounce, with oil and precious metals surging across the board.
Notably, US commercial crude inventories rose by 17.423 million barrels in a single week, the largest increase in three and a half years, while the Strategic Petroleum Reserve fell below 300 million barrels. This inventory divergence signals that the market is pricing an unusual 'high oil price plus high inventory' combination—geopolitical premium pushes prices up, but actual demand has not kept pace. For textile raw materials, the impact is layered: short-term cost push, mid-term demand suppression, and long-term supply chain restructuring.
Industry Impact
For every $10 per barrel rise in crude oil, PTA production costs increase by approximately 380-400 yuan per ton, with polyester filament costs rising correspondingly. With Brent trading in the $85-89 range, the cost floor for chemical fiber raw materials remains firm. However, downstream weaving mills face a harsh reality: terminal orders are insufficient, greige fabric inventories are high, and price increases are difficult to pass through. This 'hot upstream, cold downstream' pattern is squeezing margins across the entire textile chain.
For polyester plants, low inventories provide some pricing leverage, but OPEC and IEA have both cut their 2026 global oil demand growth forecasts. The US summer driving season is ending, refinery utilization will decline in September-October, and Q4 oil prices are likely to retreat. This suggests the current high-cost window may be temporary. Textile companies that blindly chase high raw material prices risk inventory devaluation in Q4.
From an industrial cluster perspective, polyester hubs like Shengze and Changxing have noticeably slowed procurement, with some mills keeping raw material inventories at just 7-10 days of safety stock to avoid price correction risks. Fabric traders in Keqiao are increasingly adopting 'small order, quick response' models, reducing bulk price-locking operations. This cautious sentiment itself is a vote on the persistence of geopolitical risks.
Practical Recommendations
For Procurement Teams - Monitor Brent's key support at $80 per barrel; if it breaks below, consider building hedging positions in batches to lock in Q4 production costs. - Prioritize short-term contracts (1-2 months) with polyester plants to avoid locking in high prices and maintain flexibility. - Closely track the resumption of Hormuz traffic and US-Iran negotiation signals; once the situation clarifies, increase purchasing volumes.
For Foreign Trade Enterprises - Include 'raw material price fluctuation clauses' in quotes, specifying price adjustment mechanisms when oil prices or exchange rates move beyond a certain range, to protect margins. - Use forward FX and commodity futures to hedge cost volatility, avoiding one-sided bets on oil prices. - Optimize order mix by increasing high value-added products (e.g., functional fabrics, recycled fibers) to reduce dependence on low-cost raw materials.
Geopolitical shifts are unpredictable, but the logic of cost transmission is traceable. Participants in the textile chain should focus not on predicting oil prices but on building procurement and pricing systems that can withstand violent fluctuations. When Hormuz traffic returns to pre-conflict levels, those who learned to hedge during the volatility will have a thicker safety cushion than their peers.
