Eastern Shenghong's semi-annual earnings forecast has reignited the profit debate in the polyester sector. On July 5, the company—with 2.8 million tons of PX capacity, 6.3 million tons of PTA, and over 10 million tons of total aromatics chain capacity—projected H1 2026 net profit of RMB 4.2-5.0 billion, up 987%-1195% YoY. Q2 alone saw profits of RMB 2.768-3.568 billion, nearly doubling QoQ and surging 60-78x YoY.
Dual Engines of Profit Explosion
This is not an isolated case. Hengyi earlier forecast a 2326%-2547% YoY H1 profit increase. Two forces drive this phenomenon.
First, geopolitical oil price gains. The U.S.-Iran conflict in early 2026 disrupted the Strait of Hormuz, pushing Brent crude from $61/bbl in January to $118/bbl in March, with Q2 averaging $99/bbl. Chinese refiners, with diversified crude sourcing, suffered less than Japanese and Korean peers, benefiting from wider spreads. Eastern Shenghong's integrated refining complex ran smoothly, amplifying the gain.
Second, industry 'anti-involution' capacity consolidation. The PX-PTA-polyester filament chain suffered overcapacity losses, with PTA at one point losing RMB 200/ton. But 2026 saw zero new PTA capacity and accelerated retirement of outdated capacity, ceding market share to integrated leaders. Research notes suggest the expansion cycle is near its end, and supply-demand dynamics are improving. Companies with scale and high chemical yields are best positioned.
Oil Windfall vs. Structural Improvement
Eastern Shenghong's Q2 sequential growth (93%-149%) outpaced Q1's absolute profit, indicating accelerated profit release. This correlates with Q2's higher average oil price ($99/bbl vs. Q1) and the cost-dilution effect of high-capacity utilization.
But oil prices won't stay high forever. Brent has already corrected as geopolitical tensions ease. If oil drops below $80/bbl, refining spreads will narrow. At that point, capacity consolidation becomes the key profit driver. Current PTA and polyester filament operating rates and inventory data suggest the benefits of outdated capacity retirement are just beginning, not peaking.
Downstream Implications
For weavers and fabric mills, upstream raw material costs are likely to stay elevated. PX and PTA spreads are widening, strengthening polyester filament cost support. Whether leading companies share profits downstream depends on supply-demand dynamics—higher concentration post-consolidation tilts bargaining power upstream.
Longer term, this profit surge may accelerate industry consolidation. Cash-rich leaders can invest more in differentiated products and new materials. Eastern Shenghong's push into new energy and new materials is both a profit buffer and a growth reserve.
Practical Recommendations
For Buyers - Monitor PTA and polyester filament futures; lock in forward contracts during oil price dips. - Prioritize suppliers with integrated capacity for better cost control and supply stability. - Balance long-term contracts with spot purchases to gain negotiating leverage during high-profit periods.
For Exporters - Track RMB-oil price correlation; profit surges may attract more imported raw materials, affecting domestic-international spreads. - Build strategic partnerships with leading upstream players to secure priority supply and price discounts. - Identify specific overseas capacity retirements to assess substitution opportunities in export markets.
Texworld Editorial believes this profit surge combines geopolitical luck with structural necessity. Understanding oil trends is important, but grasping supply-side changes is key to identifying the industry's turning point.
