International Oil Prices Plunge Over 4% in a Day, Cost Support for Chemical Fiber Chain Under Test

After a tug-of-war around the $70 per barrel mark, international oil prices broke through the market's psychological defense line with a long bearish candle on June 26. Light crude oil futures for August delivery on the New York Mercantile Exchange closed at $69.23 per barrel, a single-day decline of 3.74%, while Brent crude futures in London fell even more sharply, closing at $71.99 per barrel, a drop of 4.34%. For the chemical fiber industry that relies on crude oil as a core upstream raw material, this is not a short-term fluctuation to be ignored, but a key signal that could rewrite the cost logic for the second half of the year.

Cost Transmission Chain: From Crude Oil to Yarn, Every Link is Under Pressure

The impact of falling crude oil prices is neither linear nor immediately reflected in the price tags of chemical fiber fabrics. However, the transmission path is clear and certain: crude oil is the main raw material for naphtha, which is cracked to produce PX. PX is then polymerized to form PTA, which is then polycondensed with MEG to produce PET chips, and finally spun into polyester filament or staple fiber.

This means that when crude oil prices fall by nearly $4 in a single day, the forward contract prices for PX and PTA will face a significant revaluation. Industry public data shows that whenever crude oil experiences a daily decline of more than 3%, the PTA futures market often opens with a gap of 100-200 yuan per ton the next day. For polyester plants already on the edge of thin profits or even losses, this adds insult to injury.

Chain Reaction in Industrial Clusters: Inventory Depreciation and Procurement Wait-and-See

In chemical fiber industrial clusters such as Shengze, Changxing, and Xiaoshan, market sentiment quickly turned cautious after the news of the oil price crash. Weaving companies' procurement departments typically reference spot prices for PTA and MEG to lock in the cost of polyester yarn. A sharp single-day drop in oil prices means that if raw materials are purchased at the original price, they will likely face inventory depreciation in the coming days.

This 'buy on rising, not on falling' psychology will quickly spread throughout the supply chain. Upstream polyester plants' sales data are expected to decline significantly after the 26th, potentially leading to a passive accumulation of inventory pressure. Downstream weaving companies will instead digest existing inventory and delay new orders, waiting for further clarity on the cost side. This game between upstream and downstream often leads to a period of moderate decline in polyester filament yarn prices.

Dual Pressure from Global Economic Expectations and Supply-Demand Fundamentals

This oil price decline is not an isolated event; it reflects market concerns about a slowdown in global economic growth. Although OPEC+ maintains its production cut agreement, increased production from non-OPEC countries and weak global crude oil demand are eroding the support effect of the cuts. From a macro perspective, high interest rate environments are suppressing manufacturing and consumer demand. As a discretionary consumer good, textile and apparel is already under pressure from end-demand.

While falling oil prices can lower the cost of chemical fiber raw materials, which appears to benefit weaving companies, this hides a deeper contradiction: if the oil price decline is triggered by shrinking demand, then the reduction in downstream clothing orders will eventually rebound on the entire supply chain. Therefore, for industry practitioners, the cost dividend brought by this round of oil price declines is likely to be offset by order contraction.

Practical Recommendations

For Procurement Departments - Maintain a wait-and-see approach in the short term. Do not rush to replenish inventory at the bottom. After crude oil broke below $70, there is still room for further decline on the technical charts. PTA and polyester yarn prices may react with a lag. It is safer to wait for stabilization signals before building positions in batches. - Pay close attention to the basis between the PTA futures market and spot prices. If the basis strengthens, it indicates spot prices are relatively resilient, and spot purchases may be appropriate. If the basis weakens, futures hedging or point pricing models may offer a better advantage. - When signing monthly or quarterly long-term contracts with upstream polyester plants, consider including price adjustment clauses that use crude oil price fluctuations as a reference anchor for floating pricing, to hedge against the risk of a single sharp decline.

For Foreign Trade Companies - Shorten the validity period of quotations when signing export orders. With current oil price volatility, traditional 30-day fixed price quotes can easily lead to losses. It is recommended to shorten the validity period to 7-14 days and indicate that the quotation is based on the average PTA price on the date of signing. - Be vigilant about the linkage effect between the RMB exchange rate and oil prices. A sharp drop in oil prices is often accompanied by a strengthening of the US dollar, which will squeeze the profit margins of export companies. Synchronized foreign exchange hedging operations are necessary. - Use this window of cost reduction to solicit new orders from overseas customers. Make moderate concessions in fabric quotations in exchange for larger order shares. In markets such as Europe and Southeast Asia, cost advantage is currently a key competitive lever.
