On the night of July 15, international crude oil markets experienced a sharp sell-off. Brent crude, after dipping below $84 per barrel at 16:35, accelerated its decline, breaching the $83 mark by 22:52, with an intraday drop of 1.84%. Meanwhile, WTI crude settled at $78.37 per barrel, also falling over 1%.
Cost Transmission: Direct Pressure on the Chemical Fiber Chain
For the textile industry, every sharp fluctuation in oil prices means a repricing of chemical fiber costs. Major fiber varieties such as polyester filament, polyester staple, nylon, and spandex are all directly or indirectly linked to petroleum derivatives like naphtha, PX, PTA, and MEG. Brent falling below $83/barrel implies a narrowing of naphtha cracking margins, which will subsequently transmit to polyester chip processing.
Historically, when crude oil falls more than 1.5% in a single day, PTA futures typically open with a gap-down of RMB 200-300 per ton the following session. Polyester plants usually adjust their spot quotations within 2-3 working days. This means that fabric buyers in the second half of July will face a "cost-down window," but they must also be wary of inventory depreciation risks from rapidly falling raw material prices.
Regional Industrial Belt Response: Divergent Procurement Rhythms in Shengze and Keqiao
After the news of the oil crash, the two major textile clusters in China showed subtle differences in response. Polyester traders in the Shengze area largely adopted a wait-and-see approach, suspending large-volume price locks until the direction of PTA futures is confirmed after market open. In contrast, some printing and dyeing mills in Keqiao, Shaoxing, accelerated their grey fabric purchases, viewing the oil price drop as an opportunity to lower fabric costs and lock in orders for the next two weeks at current lower chemical fiber prices.
This divergence reflects differing expectations of cost pass-through speeds across the supply chain. Weaving mills are more concerned that a "buy on rising, not falling" mentality among downstream clients could cause temporary order delays, while dyeing mills focus more on the actual reduction in current raw material costs. For foreign trade enterprises, if they hold forward fabric orders denominated in USD, the room for renegotiating with suppliers is now opening up.
Data Behind the Logic: Oil Price Expectations and Textile Inventory Cycles
The timing of this oil price decline is noteworthy. July typically marks the transition between the traditional low and peak seasons for the textile industry, with the domestic market entering the autumn/winter fabric stocking phase and foreign trade beginning to negotiate orders for the following spring. According to industry public data, average polyester plant inventories currently stand at around 15-18 days, a moderately low level. This suggests that once the upstream price-cut signal is confirmed, downstream restocking demand may be quickly unleashed.
However, it must be noted that a single-day crash in oil prices does not necessarily form a trend. Since 2024, Brent crude has repeatedly oscillated in the $80-85 range. If textile companies make substantial adjustments to their procurement plans based on this single event, they risk "buying the dip at the wrong time." A more rational approach is to wait for OPEC+ statements and U.S. crude inventory data over the next week before deciding whether to increase raw material stockpiles.
