While most chemical fiber companies struggle with thin margins in PTA and polyester, Hengyi Petrochemical has delivered a startling H1 2026 earnings forecast: net profit attributable to shareholders is expected to reach 5.5-6.0 billion yuan, a year-on-year surge of 2,326% to 2,546%. This explosion is fueled by the extraordinary profitability of its Brunei refinery amid tight oil product supply in Southeast Asia, signaling that China's chemical fiber champion is breaking out from the single-track "refining-polyester" model into global energy and new materials. The profit surge is no fluke. In Q1 2026, Hengyi's net profit hit 1.995 billion yuan, up 3,773.77% year-on-year; Q2 saw a sequential increase of 76% to 101%, reaching 3.5-4.0 billion yuan. The driver is its integrated refinery in Brunei, which benefits from tight regional supply-demand dynamics, local tax incentives, market-based pricing, and low freight costs. The plant operated at full capacity with high per-ton margins, becoming the core of Hengyi's current and future earnings. Analysts at CITIC Securities note that Southeast Asian oil product spreads widened significantly in early 2026, a trend unlikely to reverse soon. For the industry, Hengyi's case highlights a key trend: overseas refinery deployment offers a competitive edge in China's oversupplied domestic market. As the only Chinese chemical fiber leader with an overseas refinery, Hengyi avoids domestic price controls and fierce competition, tapping directly into high-premium Southeast Asian markets—an advantage hard to replicate in the near term.
Three Strategic Projects to Build an Oil-Coal-Fabric Structure
Amid surging profits, Hengyi is accelerating three strategic projects to reduce reliance on single crude oil feedstock and enhance profit stability across the value chain. Brunei Phase II: optimized to 12 million tons/year capacity, producing diesel, PX, benzene, and other high-value products, targeting completion by end-2028. Total Brunei capacity will then reach 20 million tons/year, the only incremental overseas capacity among private Chinese mega-refineries. Xinjiang coal-to-ethylene glycol project: plans to produce 2.4 million tons/year of fiber-grade MEG from coal, expected to come online by H1 2028. This links coal chemicals to fiber raw materials, reducing dependence on oil-based feedstocks. Hubei Jingzhou recycling project: a 300,000-ton/year demonstration facility using waste textiles instead of crude oil as feedstock, with an 18-month construction period. Aligned with China's dual-carbon goals and textile recycling policies, it will create an integrated "oil-coal-fabric" structure post-completion. These moves signal Hengyi's transformation from a traditional refiner-polyester player into an oil-coal-fabric new materials platform. For downstream buyers, this feedstock diversification will help stabilize future polyester pricing and mitigate cost shocks from crude oil volatility.
Can the Boom Last? Three Risks to Watch
The market is questioning whether Hengyi's earnings surge is sustainable. From an industry logic perspective, tight Southeast Asian oil product supply is unlikely to reverse quickly, supporting Brunei's high profitability through the year. The PTA and polyester sectors have seen structural capacity optimization, with profit recovery poised to continue. Combined with the ramp-up of nylon projects, the full-year profit base is set for a permanent upward shift. However, industry participants should watch for: crude oil price volatility—a sharp drop could trigger inventory write-downs and narrow crack spreads; project execution risk—Brunei Phase II and Xinjiang MEG projects are capital-intensive with long lead times, facing potential delays and funding strains; regional concentration risk—core refining capacity concentrated in Brunei exposes the company to host-country policy or geopolitical shifts; and downstream demand—weak textile demand could slow polyester profit recovery.
