On July 9, international crude oil markets experienced a sharp selloff followed by a quick rebound. WTI crude fell over 3% intraday to hit a low of $72.27/barrel, while Brent crude briefly dropped below $77/barrel, down 2.48%. However, in the final trading hour, both benchmarks rallied $0.6 to close at $74.51 and $79.12 respectively. This pattern of deep intraday correction followed by rapid recovery has significant implications for the upstream cost of textile chemical fibers.
Oil Volatility and Cost Pass-Through to Chemical Fibers
Crude oil is the most upstream raw material for the polyester chain (PTA-polyester filament/staple) and the nylon chain (caprolactam-nylon). According to industry public data, a $1/barrel move in oil prices typically transmits to PTA prices within 1-2 weeks, with an impact of about 30-50 RMB/ton. For polyester filament, the cost impact is roughly 50-80 RMB/ton. On July 9, WTI's intraday drop from above $74 to $72.27—a decline of nearly $2—theoretically implied a potential 60-100 RMB/ton downward shift in PTA costs. But the late-day rebound partially reversed this, leaving closing prices little changed from the previous day.
This put chemical fiber producers in a dilemma on procurement decisions: buying at the intraday low would lock in a temporary bargain, while waiting for further declines risked missing the opportunity. In the futures market, PTA contracts followed crude's rebound in late trading, narrowing their losses, indicating that the market did not form a one-way bearish consensus.
Industrial Cluster Reactions and Procurement Psychology
Feedback from textile clusters in Shengze, Changxing, and Xiaoshan—major polyester weaving hubs—shows that loom utilization rates remain relatively high, but raw material inventories are generally low. Industry surveys indicate most weaving mills hold 7-10 days of feedstock, below the historical average of 15-20 days. This lean inventory strategy tends to trigger concentrated restocking when oil prices plunge—and indeed, when WTI fell below $73 on July 9, some traders and mills stepped up inquiry activity.
Notably, the rebound was swift: from the low of $72.27 to the close of $74.51, a gain of 3.1%. Buyers who hesitated near the bottom may have missed the best entry point. For export-oriented firms, since orders are typically priced 1-2 months ahead, short-term oil swings have limited impact on booked orders but directly pressure new quotations.
Outlook for Chemical Fiber Costs in H2
Looking at a longer horizon, the July 9 oil price swing may be a microcosm of the cost tug-of-war for the rest of the year. The global crude market faces multiple contradictions: the extension of OPEC+ production cuts versus slowing economic growth in Europe and the US, plus strong summer gasoline demand in North America. These factors make a clear trend unlikely in the near term, with oil likely to oscillate in the $70-80 range.
For the chemical fiber sector, this means cost direction for PTA and polyester is equally unclear. Polyester POY 150D/48F currently trades around 7,500 RMB/ton, down about 5% from the start of the year, with profit margins already squeezed to near break-even. If oil stays above $70, polyester costs will find support, limiting further downside. Conversely, a break below $70 could open a new leg down for chemical fiber prices.
