Iran's 60-day free transit policy at the Strait of Hormuz is injecting a short-term boost into the global chemical fiber and textile supply chain. After the Iranian government announced the removal of surcharges for commercial vessels, the geopolitical risk premium in oil prices quickly dissipated, with Brent and WTI crude oil prices falling consecutively. This shift directly impacts China's chemical fiber industry, which heavily relies on Middle Eastern imports for key raw materials like PX, MEG, and methanol. Previous channel congestion had kept raw material prices high and inventories low, compressing corporate profits for months.
Cost Transmission: From Crude Oil to Chemical Fiber
The benefits of lower oil prices are rapidly transmitting along the supply chain. Prices for upstream PX and MEG have softened first, followed by stabilization of mainstream products like polyester, PET, and nylon chips. Industry data shows that chemical fiber companies had been squeezed by high costs and weak demand, with conservative operating rates and high finished goods inventories. Now, with easing raw material costs, some firms are adjusting production schedules and attempting to rebuild feedstock stocks.
The core logic: China's chemical fiber upstream pricing is highly linked to international crude oil markets. For every $10 drop in oil per barrel, PX production costs fall by roughly 8-10%, which then drives down intermediate products like polyester chips and filament yarn. For small and medium chemical fiber mills operating near breakeven, this means a temporary margin recovery after months of compression.
Downstream Response: Restocking Picks Up
Cost relief is filtering to end fabric and apparel markets. In the first half of the year, textile companies faced sluggish orders and cautious procurement, mainly for just-in-time replenishment. As chemical fiber prices decline, fabric buyers' cost expectations improve, prompting some small and medium mills to increase inventory. Industry surveys show that fabric mills in Jiangsu and Zhejiang have raised raw material inventory days from 15 to around 20 days, with operating rates also ticking up.
Home textile and apparel brands also benefit. Lower raw material costs free up room for end-market promotions. Some brands have begun planning summer sales to stimulate consumption. However, the recovery in domestic and foreign demand remains fragile—European and American orders are slow to rebound, and Chinese consumer confidence is still recovering. Whether cost relief can translate into actual sales growth remains uncertain.
Window Risk: Geopolitical Variables After 60 Days
The transit policy is only valid for 60 days, creating significant uncertainty. Once it expires, rules and geopolitical tensions around the Strait may tighten again, potentially triggering another oil price spike. Additionally, OPEC+ production decisions and global macroeconomic slowdowns could offset the short-term benefit.
Fundamentally, the chemical fiber and textile market is undergoing a structural repair, not a full recovery. Weak end-demand remains the biggest constraint: domestic apparel retail growth is slowing, and overseas destocking cycles are not over. The cost benefit primarily eases cash flow rather than driving a new expansion cycle. Companies should avoid chasing price rallies or building excessive inventory that could become a burden when the window closes.
