A single chemical fiber giant's half-year net profit can now match the sum of several previous years. Hengyi Petrochemical's (000703.SZ) H1 2026 earnings guidance is forcing the market to reassess this company with a refinery in Brunei. According to its announcement, H1 net profit attributable to shareholders is expected between RMB 5.5 billion and 6.0 billion, a year-on-year surge of 2,326% to 2,547%. Q1 already delivered RMB 1.995 billion, and Q2 rose another 76% to 101% sequentially, reaching RMB 3.5-4.0 billion for the quarter alone.
This data reflects the dividend from persistently tight refined fuel supply-demand dynamics in Southeast Asia, as well as the payoff from Hengyi's multi-year overseas布局.
Brunei Refinery: The Profit Engine's Geographic Edge
Hengyi is the only Chinese chemical fiber leader to own an overseas refinery. Its Brunei project operated at full capacity and full sales in H1, with per-ton product margins remaining high. The core reason: Southeast Asia faces a chronic shortage of refined fuels, making refining spreads far superior to those in China. Additionally, the Brunei refinery enjoys local tax incentives, market-based pricing, and low freight and insurance costs—advantages that are amplified during industry upcycles.
On the product side, besides refined fuels, chemicals like PX and benzene also maintained high margins, further boosting the refining segment's profit. CITIC Securities analysis noted that Southeast Asian fuel spreads widened significantly in Q1 2026, driving a sharp increase in refining earnings. While spreads narrowed slightly in Q2, the tight supply-demand structure remains unchanged, and Hengyi is the biggest beneficiary of this structural dividend.
Polyester and Nylon: Dual Recovery Creates Profit Stacking
While the refining segment contributed the bulk of growth, the domestic PTA and polyester industries are also undergoing substantial supply-demand improvement. The industry's anti-internal-competition push is accelerating the exit of outdated capacity, gradually restoring PTA spreads. As a top supplier of PTA and polyester filament, Hengyi directly benefits from this repair.
The nylon chain also added incremental profits. Hengyi's nylon capacity continues to ramp up, and with downstream demand recovering, nylon product margins have improved significantly versus previous years. These two chains create a profit stacking effect, permanently lifting the company's overall profit baseline.
Three Strategic Projects: From Refining Leader to New Materials Platform
Beyond short-term profit explosion, Hengyi is advancing three strategic projects that will define its industrial form over the next five years.
- **Brunei Phase II**: Optimized to 12 million tons/year capacity, mainly producing diesel, PX, and benzene, targeting completion by end-2028. This will bring total Brunei capacity to 20 million tons/year, creating deep industrial synergy. It is the only overseas capacity addition among private mega-refiners in recent years, making it strategically scarce.
- **Xinjiang Coal-to-Ethylene Glycol**: Plans to produce 2.4 million tons/year of high-quality fiber-grade coal-to-EG, expected to start operations in H1 2028. This project will open a raw material pathway from coal to chemical fiber, reducing sole dependence on crude oil.
- **Hubei Jingzhou Recycled New Materials**: A 300,000-ton/year recycled new materials industrial demonstration project, using waste textiles as feedstock instead of crude oil, with an 18-month construction period. This aligns with China's dual-carbon strategy and waste textile recycling policies, promising both economic and social benefits.
Once these projects are operational, Hengyi will form a new 'oil, coal, and fabric' parallel structure. For downstream textile buyers, this means significantly improved raw material supply stability and diversity—especially amid volatile crude oil prices, where coal-to-EG and recycled textile routes will provide cost hedging.
Can the Boom Last? Risks Alongside Certainty
The market naturally wonders if this profit surge can continue. From an industry logic perspective, the tight supply-demand for Southeast Asian refined fuels is unlikely to reverse quickly, so the Brunei refinery's high margins should sustain for the full year. The PTA and polyester sectors have seen substantial capacity optimization, making profit recovery sustainable. Combined with the nylon project's ramp-up, the full-year profit center will be permanently higher than previous years.
However, several risks warrant attention:
- Sharp fluctuations in international crude oil prices could lead to inventory write-downs and margin compression if prices fall rapidly;
- Projects like Brunei Phase II and Xinjiang coal-to-EG involve large investments and long construction periods, posing risks of delays or funding pressure;
- Concentrating core refining capacity in a single Brunei location exposes the company to host-country policy and geopolitical changes that could impact cost advantages and supply stability;
- If downstream textile demand disappoints, it will affect the pace of polyester profit recovery.
Implications for the Textile Supply Chain
Hengyi's profit explosion is not an isolated event; it signals a redistribution of profits upstream in the chemical fiber industry. For downstream weaving and garment manufacturers, raw material costs have risen in H1 2026, but it's crucial to note that Hengyi's profit growth mainly came from its overseas refining segment, not from domestic polyester price hikes. This means the PTA and polyester supply-demand repair hasn't yet translated into end-product price increases, leaving room for downstream buyers to negotiate.
In the medium to long term, after Hengyi completes its 'oil-coal-fabric' integration, the raw material side will form a diversified supply system, which is positive for textile supply chain stability. In particular, the coal-to-EG and waste textile recycling projects will directly increase the supply elasticity of chemical fiber raw materials, helping to smooth future price fluctuations.
