International oil prices have seen a notable correction in June 2026, with Brent and WTI crude falling for consecutive days. The trigger is Iran's announcement of 60-day free passage for commercial vessels through the Strait of Hormuz, canceling additional transit fees. This policy quickly stripped the risk premium built up from previous geopolitical tensions, easing global crude supply in the short term.
Cost Transmission: From Crude to Chemical Fibers
The Strait of Hormuz handles roughly one-third of global seaborne crude oil. Changes in transit costs directly impact international oil prices. After the free passage policy, backlogged crude capacity was released, alleviating supply tightness. The oil price decline quickly transmitted to the chemical fiber chain, with core feedstocks like PX, MEG, and methanol softening.
China's chemical fiber industry relies heavily on imported raw materials from the Middle East. Earlier channel congestion led to low feedstock inventories and high prices, squeezing corporate margins. Now, with the channel open and cheaper materials arriving, upstream cost pressure has eased significantly. Major products like polyester, PET, and nylon have stabilized, and market activity is picking up.
Industry Reality: Repair, Not Reversal
Despite the cost relief, the industry still faces a structural dilemma of high costs and weak demand. In the first half of the year, textile end-users saw sluggish order intake, with downstream firms mostly restocking on a need-to basis. The drop in chemical fiber feedstock prices has released some pressure but has not fundamentally changed the weak demand picture.
From a transmission perspective, chemical fiber plant utilization remains conservative, and inventory levels are still high. The cost dividend takes time to flow downstream, and the sustainability of this recovery hinges on end-consumer demand. Home textiles and apparel have gained room for promotions, but consumer willingness to spend still requires a supportive macroeconomic backdrop.
Window Risks and Medium-Term Variables
The free passage policy is only a 60-day short-term measure. After it expires, the Strait's transit rules and geopolitical situation remain uncertain, potentially triggering another oil price swing. This means chemical fiber firms cannot rely heavily on this dividend for large-scale expansion or hoarding.
Medium-term trends depend on two variables: subsequent oil price movements and the pace of textile demand recovery. Global economic growth is slowing, European and American markets are recovering slowly, and competition from Southeast Asian textile capacity is intensifying. China's chemical fiber industry should use this cost repair window to optimize inventory structures and repair profit margins, while preparing risk plans for possible policy reversals.
