Brent crude opened near $89 per barrel as Hormuz Strait traffic fell to just 10-15% of pre-conflict levels, with Middle East crude loadings dropping from 20 million barrels per day in early July to 12 million. For the textile industry, this is not just a geopolitical headline but a clear signal that fiber costs are about to be repriced. Oil accounts for over 80% of PTA production costs, and PTA is the core feedstock for polyester filament, meaning the price transmission chain from crude to yarn could be recalibrated within weeks.
Event Background
The immediate trigger is the escalation of US-Iran tensions. Iranian military commander Hattami publicly banned US forces from the Persian Gulf, the Gulf of Oman, and the Hormuz Strait, and offered a $30,000 reward for capturing or killing American aggressors. The blockade has created a real supply gap of 8.3 million barrels per day compared with pre-war output, transforming a risk premium into an actual logistics bottleneck. Meanwhile, Russia and Ukraine continue to strike each other's energy and transport infrastructure, amplifying supply uncertainty.
US political moves also matter. Trump ordered a reduction in US-South Korea joint military exercises, citing costs and signaling a desire to ease tensions with North Korea. He also revealed that South Korea declined to cooperate on Iran's denuclearization. While Northeast Asian geopolitical risks have eased slightly, the Middle East remains tense. Egyptian President met with Kushner to push for a Gaza ceasefire, but negotiations are still dragging.
Industry Impact
For textile industrial clusters, cost transmission is not simultaneous. Polyester hubs like Shengze and Changxing typically lag raw material price changes by one to two weeks, while traders in Keqiao prefer to wait. Global crude and refined product inventories are at five-year lows, with US commercial crude stocks rising by 17.423 million barrels in a week—the largest gain in 3.5 years—and strategic reserves falling below 300 million barrels. Low inventories support prices, meaning fiber raw materials will have strong cost support in the short term.
However, demand-side headwinds are accumulating. OPEC and IEA have both cut their 2026 global oil demand growth forecasts. The US summer driving season is ending, and refinery run rates will decline in September-October. For textiles, this suggests that terminal order recovery may disappoint, and downstream weaving mills will face the dual pressure of rising raw material costs and insufficient orders. The supply gap is expected to narrow in Q4, and oil prices will likely correct downward, but before that, fiber prices may remain elevated and volatile.
Practical Recommendations
For Buyers - Avoid panic stockpiling in the short term; watch for hedging opportunities when oil prices fall below $80 per barrel. - Include price adjustment clauses in quarterly contracts with fiber suppliers to hedge against geopolitical volatility. - Prioritize locking in medium- to long-term orders for PTA and polyester filament, reducing spot purchases.
For Exporters - Add raw material price linkage mechanisms to export quotes to protect margins from cost inflation. - Monitor Hormuz Strait traffic recovery; if low transit persists, adjust shipping logistics and delivery schedules accordingly. - Use futures to hedge raw material costs, but maintain strict position limits to avoid one-way bets.
With geopolitical risks intertwined, oil market volatility will be a core variable for textile raw material prices. All players in the supply chain should reassess inventory management and pricing strategies to prepare for potential cost shocks.
