On June 12, international crude oil markets experienced a severe shock. WTI crude futures fell as much as 5% during the day, closing at $83.32 per barrel, while Brent crude slumped 6% to $88.12 per barrel. This marked the first time since mid-April that WTI broke below the $85 threshold, with the single-day drop being the largest in nearly two months.
For the textile industry, crude oil volatility is never an isolated event. As the direct upstream for synthetic fibers such as polyester, nylon, and polypropylene, crude price changes cascade through the chain: crude → naphtha → PX → PTA/ethylene glycol → polyester chips → polyester filament/spun yarn. This crash means that the cost support for chemical fiber raw materials is being rapidly eroded.
Background and Drivers
The crash was primarily driven by geopolitical factors. Trump delivered public remarks on the Iran issue, followed by Iranian media disclosing new details of a U.S.-Iran memorandum of understanding. Markets interpreted this as a potential phase of détente, sparking expectations of resumed Iranian crude supply. Under supply-side pressure, speculative funds rushed to close positions, accelerating the price decline.
Meanwhile, the CME announced an extension of WTI crude trading to a 7×24 hour model. This institutional change means greater liquidity in the pricing mechanism, allowing price volatility to be fully priced in during non-traditional trading hours. For textile firms relying on night sessions for risk management, this adds complexity to price monitoring and hedging.
Notably, Brent crude fell more (6%) than WTI (5%), highlighting the vulnerability of the global benchmark. Brent, a key reference for Asian chemical fiber raw material imports, will have a more direct impact on PTA and MEG import costs.
Industrial Impact: From Cost Collapse to Procurement Wait-and-See
The cost shock will first hit the polyester chain. According to public industry data, the correlation coefficient between PTA prices and crude oil has remained above 0.8 for a long time. A 5% drop in crude theoretically reduces PTA costs by about 300-400 yuan per ton. If the decline continues, polyester chip and filament yarn quotations will face downward pressure within the coming week.
For the weaving sector, especially mid-to-low-end fabric producers using polyester, raw material costs account for 60%-70% of total costs. A sharp drop in raw material prices means in-transit and finished goods inventories face write-down risks. Factories in polyester clusters like Shengze, Changxing, and Xiuzhou may be forced to accelerate destocking, even leading to a "buy on rising, not on falling" procurement freeze.
From the perspective of downstream apparel buyers, falling raw material prices are usually interpreted as impending fabric price cuts. Brands and traders may delay orders, waiting for lower price confirmations. Once such wait-and-see sentiment takes hold, it will suppress polyester plant operating rates, creating a negative feedback loop: prices fall → demand shrinks → prices fall further.
Impact on Exports and Trade
China is the world's largest chemical fiber producer, with polyester filament and spun yarn exports rising steadily. The crude crash reduces costs in RMB terms, theoretically helping to lower export quotes and enhance the competitiveness of Chinese chemical fiber products. However, overseas buyers are also watching oil trends; if they expect further declines, they will delay purchases.
Moreover, Brent's larger drop than WTI means that Asian PX and MEG import costs—benchmarked to Brent—may fall more than expected. This is positive for domestic PTA producers: lower imported raw material costs, but product prices will follow the market down. Whether profit margins expand depends on the spread between cost reduction and product price decline.
