A single quarter net profit for a polyester giant surged 93% to 149% sequentially and 60 to 78 times year-on-year. This is not a fluke for a small player but the Q2 2026 result for Eastern Shenghong, following rival Hengyi Petrochemical's forecast of over 23-fold net profit growth for the first half. Two industry leaders simultaneously reporting explosive earnings signals a rare profit boom cycle in the polyester chain.
Geopolitical Conflicts: Asymmetric Benefits from Oil Price Surge
In early 2026, escalating US-Iran tensions blocked shipping through the Strait of Hormuz, driving Brent crude from $61/barrel in January to $118/barrel in March, with Q2 averaging $99/barrel. This geopolitical oil surge did not benefit all refiners equally.
The key lies in procurement diversification. Chinese refiners have long diversified sources from the Middle East, Africa, and South America, while countries like Japan and South Korea rely more heavily on the single strait. When Hormuz was blocked, integrated Chinese refiners became 'asymmetric beneficiaries'—enjoying wider margins without supply disruption. Eastern Shenghong, with 2.8 million tons/year PX capacity and 6.3 million tons/year PTA capacity, saw its entire crude-to-PX-to-PTA-to-polyester chain's spread expand significantly.
Anti-Involution: Capacity Clearance Unleashes Structural Dividends
Oil prices explain the 'volume' of profit expansion, but the real shift in industry ecology comes from capacity structure changes. Over the past two years, the PX-PTA-polyester filament chain suffered 'involutionary losses,' with PTA losing up to 200 yuan per ton. In 2026, the situation reversed: no new PTA capacity came online, and outdated capacity at home and abroad accelerated exit.
Institutional research indicates the industry expansion cycle is nearing its end, and with ongoing 'anti-involution' policies, supply-demand dynamics are set to improve fundamentally. Eastern Shenghong's performance guidance explicitly cites 'improved supply-demand in petrochemicals' as a main driver. This means even if oil prices retreat due to geopolitical easing, profit margin recovery from capacity clearance will persist—large players with scale, cost advantages, and high chemical yields are best positioned to benefit.
Chain Transmission: Profit Redistribution from Refining to Textiles
What does the polyester giants' profit surge mean for downstream textile mills? In the short term, upstream raw material costs rise. PTA and polyester filament prices track oil, squeezing weaving and apparel margins. In the long term, however, capacity clearance reduces price dumping, allowing pricing to return to reasonable profit levels and fostering a healthier supply chain.
For textile clusters like Shengze and Keqiao, raw material price volatility is a perennial challenge. In H1 2026, integrated leaders' profit explosion came more from refining than squeezing downstream. Eastern Shenghong's integrated refining project ran smoothly with high utilization, indicating no output cuts to support prices.
