A recent analysis suggests that, amid the Middle East crisis, the polyester industry's profitability has surprisingly improved, even as supply-demand fundamentals remain weak.

Strategic adjustments by corporate management are beginning to play a crucial role. The polyester filament supply chain has undergone a positive shift in operational tactics during the crisis, allowing profitability to rise against the trend.

If these adjustments become permanent, they could lift profit margins for polyester filament and PTA to new levels.

Industry's trading range is breaking out

Leading polyester filament companies have spent years enhancing their vertical integration, transitioning from chip spinning to melt direct spinning, building in-house PTA units, boosting PTA competitiveness, and developing integrated PTA-filament bases through a petrochemical mindset.

By leveraging their competitive advantages, these leaders have steadily increased their market share in both filament and PTA. By 2025, the top two filament players account for nearly half the market, while the top four PTA firms hold two-thirds of the share.

However, this rise in competitiveness and share has paradoxically led to a decline in the industry's profit midpoint and a narrowing of volatility. Spread data shows that from 2023 to 2025, price spreads for polyester filament and PTA were confined to a relatively narrow band.

Since this year, despite the poor supply-demand landscape, the industry's profitability has markedly improved under the influence of the Middle East crisis.

Divergent responses to the crisis

The current Middle East crisis has had an unusually large impact on supply and demand. In the PTA segment, the conflict has reduced feedstock PX supply since April, prompting PTA producers to proactively adjust operating rates, thereby sustaining profit margins.

In contrast, similar products have performed poorly. For example, in the benzene-adipic acid chain, operating rate cuts for adipic acid lagged behind upstream benzene, causing adipic acid profitability to drop significantly after the conflict.

For polyester filament, the analysis points to adjustments in both operating rates and pricing strategies. Compared to the 2022 Russia-Ukraine conflict, the current period has seen downstream buyers actively destocking under worse demand conditions, yet filament players have managed to preserve healthy margins.

If these crisis-driven operational adjustments become permanent, they could allow leading companies to establish a new, higher profit plateau.
