Rising Risk in the Strait of Hormuz Puts Short-Term Pressure on Textile Raw Material Costs

Crude oil prices surged more than 5% in a matter of hours, with Brent crude hitting $79 per barrel and WTI rising nearly 4.75%. For the textile industry, this is not an isolated financial event—oil is the primary feedstock for synthetic fibers such as polyester, nylon, and polypropylene. Every dollar swing in oil prices triggers a quantifiable chain reaction in chemical fiber costs.

Background

The immediate trigger for this oil price spike is renewed geopolitical tension in the Middle East. Following reports of U.S. military strikes against Iran, the market quickly priced in risk. Iran's state media then stated that any new attack would lead to the closure of the Strait of Hormuz—a chokepoint that carries roughly one-third of the world's seaborne oil trade.

Examining the timeline, oil prices climbed in stages during the trading session: first Brent crude rose over 1%, then both benchmarks surged more than $1, with intraday gains expanding from 2% to 3%, then 4%, and finally Brent's gain reached 5% by the close. The three-month Brent futures spread hit $2.36 per barrel during the session, the highest since June 16—a widening spread typically signals a stronger market expectation of near-term supply tightness.

Industry Impact

For the textile sector, the most direct impact hits the chemical fiber segment. In the cost structure of polyester staple fiber and filament, PTA and MEG account for over 70%, and both are derived from naphtha cracking. A 5% rise in oil prices could theoretically push polyester costs up by approximately 3%-4%.

Feedback from industrial clusters in Shengze, Changxing, and Xiaoshan indicates that traders have begun to tighten quotations. Some polyester plants suspended promotional activities and shifted to a wait-and-see stance after the oil price shock. This follows the industry's established transmission logic: when oil prices spike, upstream polyester plants tend to freeze prices or raise them, while downstream weaving mills face a dilemma—buying at the peak or risking a supply gap by waiting.

Notably, this event occurs during the transition period between the traditional low and peak seasons for textiles. The third quarter typically marks the start of autumn/winter fabric preparation, where home textile and apparel orders are highly sensitive to raw material costs. If oil prices remain elevated, chemical fiber prices are likely to follow, squeezing profit margins for weaving mills—especially small and medium-sized ones with limited pricing power.

On the export front, the impact is more complex. China's chemical fiber and fabric exports are denominated in U.S. dollars. Higher oil prices push up bunker fuel costs, thereby raising ocean freight rates. Meanwhile, if the Middle East situation remains tense, container shipping routes transiting the Strait of Hormuz may face diversions or higher insurance premiums, further extending delivery lead times.

Practical Recommendations

For Buyers - Consider moderately increasing lock-in volumes for chemical fiber raw materials in the short term, but avoid excessive chasing of highs. Use futures tools to hedge price risk, or negotiate short-term floating price agreements with suppliers. - Monitor inventory data and operating rates for PTA and MEG. If downstream polyester operating rates do not decline in tandem, it suggests that cost transmission has not fully materialized, allowing for opportunistic replenishment on pullbacks. - Confirm with logistics providers the latest surcharge policies for Middle East routes, and calculate landed costs in advance to avoid order losses from sudden freight rate changes.

For Export Enterprises - Include price adjustment clauses in export contracts, specifying that if raw material prices fluctuate beyond a certain threshold, both parties will renegotiate unit prices. This helps share the uncertainty arising from geopolitical events. - Prioritize short-term and quick-turn orders, reducing exposure to long-term contracts. In the current environment, quote validity should be shortened to 3-5 days to prevent secondary oil price volatility from eroding profits. - Evaluate alternative routing: if the Strait of Hormuz is blocked, pre-discuss with carriers the option of diverting via the Cape of Good Hope, calculate the additional time and cost, and incorporate this as a contingency plan in customer communications.
