A semi-annual performance forecast from a domestic chemical fiber giant has laid bare the leverage that refining exerts on upstream profits in the textile chain. Hengyi Petrochemical expects H1 2026 net profit attributable to shareholders to reach RMB 5.5-6.0 billion, a surge of over 23 times year-on-year. This is no cyclical blip; it reveals the true strategic value of overseas refining capacity under the persistent supply-demand tightness in Southeast Asian refined oil markets.
Profit Structure: Brunei as the Engine, PTA and Nylon as Assist
In Q1, Hengyi's net profit hit RMB 1.995 billion, up more than 37 times. In Q2, it rose another 76%-101% sequentially, contributing about RMB 3.5-4.0 billion. The growth is not from a single segment but from a trifecta of refining, polyester, and nylon. The Brunei refinery is the core driver. Long-term tight supply in Southeast Asia widened crack spreads in early 2026, and Brunei's tax incentives, market-based pricing, and low freight costs kept per-ton profitability high. Meanwhile, PTA and polyester industry 'anti-involution' measures have optimized capacity and boosted margins, while nylon chain capacity release added incremental gains.
Three Strategic Projects: From Single-Leg to a 'Oil-Coal-Fabric' Triangle
Hengyi is not resting on its laurels. It is pushing three major projects to reshape its industrial boundaries:
- **Brunei Phase II**: Capacity optimized to 12 million tons/year, targeting completion by end-2028. Total Brunei capacity will then reach 20 million tons/year, making it the only incremental overseas capacity among private mega-refineries in recent years.
- **Xinjiang Coal-to-Glycol**: Planned 2.4 million tons/year of high-quality fiber-grade coal-to-glycol, expected online by H1 2028. This will reduce reliance on crude oil and leverage China's abundant coal resources.
- **Hubei Circular New Materials**: A 300,000 tons/year demonstration project using waste textiles as feedstock, with an 18-month construction period. This aligns with China's 'dual-carbon' strategy and opens a new raw material source.
Once operational, Hengyi will run on three parallel raw material routes: oil, coal, and fabric. For the textile industry, this means greater upstream supply diversification and stability, especially the waste textile recycling project, which could offer a replicable commercial path for green chemical fiber.
Sustainability: Three Risks and One Certainty
The key question is whether this profit surge can last. Industry logic suggests Southeast Asian refined oil supply tightness will not reverse quickly, sustaining Brunei's high margins through the year. PTA and polyester capacity cleanup supports continued margin recovery. Thus, the full-year profit baseline is likely to shift permanently upward. However, risks remain:
- **Crude oil volatility**: A sharp price drop would compress crack spreads and trigger inventory write-downs.
- **Project execution**: Phase II and coal-to-glycol are large-scale, long-cycle, and face delays or cost overruns.
- **Geopolitical and policy risk**: Concentrating core refining capacity in Brunei exposes the company to host-country policy shifts and regional instability.
For downstream textile buyers, Hengyi's strong performance implies greater upstream supply stability for PTA, PX, and glycol, but price volatility persists. Procurement teams should closely track Phase II and coal-to-glycol progress, as their commissioning will directly impact future raw material price benchmarks.
