900 yuan per barrel. That number appeared for the first time in the history of China's crude oil futures. On the morning of September 14, the main contract 2610 surged to 908.7 yuan per barrel intraday, closing at 902 yuan, a single-day gain of 11.37%. For the textile industry, this is not a futures headline — it is an invoice about to be transmitted to the cost side.
Where the Cost Transmission Chain Breaks
Crude oil, as the mother of commodities, transmits price fluctuations downstream along a clear refining chain: crude — naphtha — PX — PTA. PTA, as the core raw material for polyester, should theoretically bear the brunt of cost increases. Yet this time PTA did not surge in tandem, because internal supply and demand formed a counterbalancing force.
Previously idled PTA units have been restarting, operating rates have recovered, and social inventories have accumulated slightly. Meanwhile, the downstream polyester sector's "Golden September and Silver October" peak season has fallen short, terminal weaving orders are being released slowly, and downstream willingness to accept high-priced raw materials is limited. Cost support and real demand pull against each other, pushing PTA into a range-bound pattern rather than a one-way rally.
This means the cost transmission chain shows a clear "break point" at the PTA stage — upstream price increases cannot be fully passed downstream, and midstream factories are forced to absorb part of the cost pressure. For buyers, the probability of a sharp PTA correction in the short term is low, but the risk of chasing highs should not be ignored.
The Real Elasticity of Cotton-Polyester Substitution
At the other end of the textile chain, ICE cotton futures are caught between rising chemical fiber costs and their own supply-demand fundamentals. Recently, the ICE US cotton main contract has maintained weak fluctuations: drought in US cotton-growing regions and expectations of lower new-crop output provide support, but USDA supply-demand reports showing global inventories above market expectations have triggered profit-taking by longs, capping upside room.
There is a substitution relationship between cotton and polyester staple fiber. When PTA drives chemical fiber costs higher and polyester prices rise, textile enterprises tend to increase their cotton usage ratio, bringing indirect demand support. But the extent to which this logic materializes depends on terminal consumption. If overall textile end-user consumption remains weak, the substitution pull will be significantly diminished.
Currently, ICE cotton is more driven by global cotton planting, export, and consumption fundamentals. Crude oil's impact on it is an indirect exogenous variable, mainly amplifying volatility rather than determining direction. For factories, changes in the cotton-polyester price spread deserve more attention than the absolute price of crude.
Midstream Margins Squeezed from Both Ends
From a macro perspective, the impact of high oil prices is not limited to futures screens. If oil prices remain elevated over the next six months, cost pressure will transmit outward level by level: rising upstream fuel and chemical raw material prices push up logistics rates, manufacturing raw material expenses increase, affecting corporate cash flow and investment willingness.
The textile industry is equally under pressure. Upstream energy and chemical raw material prices are rising, downstream terminal consumption transmission is sluggish, and midstream factory profits are easily squeezed from both ends. The industry's "strong upstream, weak downstream" pattern is further highlighted. Weaving enterprises face the dual dilemma of rising raw material costs and difficulty in raising finished product prices, making cash flow management increasingly important.
Geopolitical tensions remain the biggest uncertainty. International investment banks have already offered predictions for extreme scenarios: if oil exports through the Strait of Hormuz are blocked for an extended period, Brent crude breaking through $120 per barrel is quite possible; if the conflict continues through year-end, Brent is likely to fluctuate in the $95-120 per barrel range. But as soon as the situation releases easing signals, the previously accumulated geopolitical premium will quickly dissipate, and oil prices may face a deep correction.
