The moment Brent crude crossed $100 per barrel, the pricing logic of the polyester chain was rewritten. Most chemical futures hit new highs intraday, with PX leading gains at over 2%, but the afternoon pullback told a clearer story: cost-side momentum is colliding head-on with demand-side drag.
Supply Side: PX Runs Rebound Fast, PTA Processing Fees Squeezed to 400 Yuan
Domestic PX operating rates have rebounded sharply from below 60% to around 77%, driven mainly by restarts at Weilian, Shenghong, and Fuhua. Other Asian facilities have also raised runs, and the Huajin Aramco new plant is expected to release capacity in October-November. In mid-to-late September, more restarts are planned at Fuhua, Hainan Refining, and Yangzi Petrochemical, while Urumqi Petrochemical shuts for two weeks. The direction of rising domestic supply is clear. However, Asian refinery feedstock remains constrained by strait navigation, making a large-scale run increase difficult.
PTA supply is returning even more directly. Since mid-August, beyond several upstream-integrated restarts, units at Dushan Energy, Yisheng New Materials, and Jiaxing Petrochemical have come back online, pushing operating rates visibly higher. As supply pressure builds, processing fees have fallen to around 400 yuan per ton. For mills, this means per-ton profit margins are compressed to levels requiring precise calculation of power consumption and depreciation, and any spike in feedstock prices could breach the break-even line.
MEG follows a different logic. Widespread shutdowns in the Middle East combined with strait navigation disruptions mean the import gap cannot easily be filled by domestic idle capacity or other regions. Imports have fallen sharply since Q2, supply has tightened continuously, and geopolitical tensions keep delaying expectations of an import recovery. MEG imports are expected to stay below 200,000 tons in September-October, keeping spot liquidity tight. This makes MEG far more sensitive to geopolitical shifts than other polyester feedstocks.
Demand Side: What 70% Staple Fiber and 60% Bottle Chip Runs Tell Us
Downstream polyester performance contrasts sharply with the hot feedstock market. Since mid-August, profits at staple fiber and bottle chip plants have been continuously squeezed, processing fees have hit repeated lows, and more producers have been forced to cut output. Staple fiber operating rates have fallen to around 70%, while bottle chip plant runs have dropped to a historic low of 60%.
These cutbacks are not strategic adjustments but passive contractions forced by margins. Against a backdrop of repeated geopolitical flare-ups and high feedstock price volatility, downstream buying has become pulse-like:观望 when prices rally, restocking when prices soften, with a generally cautious mindset. September polyester runs are expected to stay below 80%, and the traditional peak season will likely underperform.
One easily overlooked transmission chain: the higher feedstock prices rise, the less downstream dares to stock up; the less downstream stocks up, the more spot liquidity concentrates in trading hands, amplifying price swings. Staple fiber and bottle chip cutbacks are essentially a defense against this volatility.
The Tug-of-War Between Cost and Demand: Who Lets Go First?
Despite weak demand, polyester futures and spot prices are being passively lifted by continuously rising costs. Holly Futures believes Middle East geopolitical disruptions will be hard to eliminate in the short term, and the polyester market is expected to remain relatively strong on cost support.
But the phrase "relatively strong" masks structural divergence. PX and PTA supply is recovering, MEG supply is tightening, and downstream runs are falling—three forces pulling in different directions. If geopolitics ease, suppressed downstream demand could rebound and lift the market; if tensions persist, cost support remains, but downstream cutbacks may widen further.
For buyers, the most dangerous move now is chasing rallies and panic-selling. When feedstock prices are driven by geopolitical events, the effectiveness of technical signals drops sharply. For mills, PTA processing fees at 400 yuan per ton and record-low staple fiber and bottle chip fees mean production scheduling and inventory days must be reassessed.
