China's three biggest state-owned oil companies all saw earnings decline in the first half of 2025, with Sinopec taking the heaviest hit.


- Sinopec feels the squeeze: Its downstream-heavy model left it exposed to weak fuel and chemical demand. Refining profit plunged 52.5% YoY, chemical losses deepened, and sales profit fell 42.3%, making it the weakest performer of the three.
- CNOOC dragged by oil slump: With more than 80% of revenue tied to upstream exploration and production, the company struggled to offset a 15% drop in Brent crude, halting growth in what had been its most resilient business.
- Capex cuts signal caution: PetroChina and Sinopec both scaled back 2025 investment. Sinopec trimmed its budget by an extra 5% from the initial plan - 11% below 2024 levels -highlighting a cautious stance in a weaker market.
- Pivot to growth sectors: Even as they tighten traditional spending, PetroChina and Sinopec are ramping up investment in renewables and high-end chemicals. PetroChina is leaning into renewable power and specialty chemical materials, while Sinopec focuses on integrated refueling network expansion and refinery upgrades.
