Oil Price Plunge 4.34% in a Single Day: New Cost Pressure Test for Textile Chemical Fibers

Crude oil prices experienced a steep decline on June 26. Light crude oil futures for August delivery on the New York Mercantile Exchange settled at $69.23 per barrel, a single-day drop of 3.74%; on the same day, London Brent crude futures for August delivery closed at $71.99 per barrel, a more severe decline of 4.34%. During the session, WTI briefly fell below $68.5, while Brent momentarily lost the $72 threshold.

For the textile industry, these numbers are not just macroeconomic news but a signal of an upcoming new round of cost pressure testing on the chemical fiber end.

Cost Transmission: Immediate Reaction in the Polyester Chain

Crude oil is the most upstream raw material in the polyester industrial chain. From crude oil to naphtha, PX (paraxylene), then to PTA (purified terephthalic acid) and MEG (monoethylene glycol), and finally polymerization into PET (polyethylene terephthalate) chips and spinning into polyester filament or staple fiber, price fluctuations at each link transmit downstream.

Based on historical experience, when crude oil falls more than 3% in a single day, PTA futures typically open 1.5% to 2.5% lower the next trading day. Polyester filament yarn (FDY, POY, DTY) factory ex-plant prices usually adjust within the following 2 to 3 working days, depending on inventory levels. With Brent's decline approaching 4.5%, the cost side of PTA is expected to face a collapse pressure of approximately 300 to 400 RMB per ton.

For polyester plants, this is both a risk and a window. Companies holding high-cost raw material inventories will see paper losses expand rapidly; but those maintaining low inventory strategies can purchase at lower costs after the cost collapse, thereby gaining profit margins in the next round of finished product sales.

Industrial Belt Response: Wait-and-See Sentiment Among Jiangsu-Zhejiang Weaving Mills

After the news of the oil price crash broke on the evening of June 26, inquiry volumes in major textile clusters such as Shengze, Keqiao, and Changxing increased significantly the following day. According to publicly available industry information, some weaving mills suspended raw material procurement for the day, shifting to a wait-and-see mode.

This wait-and-see stance is not unfounded. Polyester filament yarn had experienced a small price hike in mid-June, with POY 150D/48F mainstream quotes around 7,600 RMB per ton. If crude oil continues to weaken, polyester plants will likely lower ex-plant prices during month-end settlements, potentially making procurement costs 5% to 8% lower than current levels. For small and medium-sized weaving mills with profit margins typically below 8% on orders, this price difference can determine an order's profitability.

However, waiting also carries risk. If oil prices only experience a short-term sharp drop followed by a quick rebound, buyers waiting for lower prices may miss the window for bargain restocking. During the June 26 session, WTI quickly recovered from $68.47 to $69.2, indicating market long-short contention.

Export Orders: The Dual Variables of Exchange Rates and Oil Prices

For Chinese textile export enterprises, the impact of falling oil prices is not unilaterally positive. Lower polyester fabric costs can enhance quotation competitiveness, but this effect is often offset by another factor—the RMB exchange rate.

Crude oil is priced in US dollars, and a sharp oil price drop is usually accompanied by a stronger dollar. On June 26, the US dollar index moved slightly higher during the oil price decline. For export orders settled in US dollars, if the RMB weakens against the dollar, the RMB income from settlement will shrink, partially offsetting the profit improvement from lower raw material costs.

Furthermore, Southeast Asian textile competitors (Vietnam, Bangladesh) also benefit from the global oil price drop, as their chemical fiber raw material procurement costs decline simultaneously. Chinese enterprises' cost-side relative advantage has not expanded due to the oil price drop; the competitive focus remains on delivery reliability, quality consistency, and trade compliance capabilities.

Outlook: Range-Bound or Trend Down?

Technically, WTI crude oil has strong support around the $68 level, a low point tested multiple times over the past three months. If $68 breaks, the next support level is near $65. Brent is facing a directional choice in the $71 to $72 range.

Fundamentally, OPEC+ production cut agreements remain in place, but global demand expectations are under pressure due to slowing growth in major economies. For the textile industry, what deserves more attention is the change in profit distribution along the polyester chain. During sharp oil price drops, PTA processing margins are often compressed, while polyester filament profits may improve temporarily due to lower raw material costs.

Practical Recommendations

For Procurement Managers - Adopt a "staggered price-locking" strategy in the short term: when PTA futures fall more than 2%, place small batch orders in stages to avoid heavy one-time positions. - Monitor polyester plant inventory days data: if inventories exceed 15 days, the probability of month-end price cuts is higher, allowing deferral of large orders. - Negotiate price protection clauses with suppliers: stipulate that if raw material prices drop more than 3% before delivery, settlement will be at the new price.

For Export Enterprises - Include a "crude oil price fluctuation adjustment mechanism" in quotation validity clauses: when Brent crude fluctuates more than 5% in a single week, quotations automatically trigger recalculation. - Assess the USD exposure of existing orders: if the RMB exchange rate shows abnormal movement during oil price declines, lock in exchange rates in advance through forward settlements. - Monitor raw material procurement quotations from Southeast Asian competitors: if they significantly lower prices due to falling oil prices, prepare alternative fabric solutions to retain customers.
