China Petroleum & Chemical Corporation (Sinopec, SSE: 600028 / HKEX: 386) is the world's largest oil refiner, processing ~280 million tonnes of crude oil per year. China's NDRC fuel price controls mean Sinopec often loses money refining when Brent is above ~$100/bbl — making it an inverse Brent proxy compared to upstream peers like CNOOC.

China's Fuel Price Control — The Core Risk
China's NDRC sets domestic fuel prices. When global crude rises sharply, domestic retail prices are capped or adjusted with a lag — compressing Sinopec's refining margins. At Brent above ~$100/bbl, Sinopec often loses money on refining operations. This makes Sinopec structurally different from refiners in deregulated markets.
Petrochemicals — The Margin Buffer
Sinopec's petrochemical division (ethylene, propylene, polymers) is less regulated and can partially offset refining losses when fuel margins are compressed. The integration of refining and chemicals is Sinopec's key structural advantage.

Why does China cap fuel prices?
The NDRC caps domestic fuel prices to control inflation and protect consumers. Prices adjust with a lag based on crude oil movements — compressing Sinopec's margins when crude spikes.
How does Sinopec compare to CNOOC?
CNOOC is upstream E&P — it benefits when Brent rises. Sinopec is downstream refining — often hurt when Brent rises due to price controls. They are structurally opposite in Brent correlation.
Is Sinopec affected by Hormuz?
Significantly. Sinopec imports ~50% of crude from Middle East via Hormuz. The 2026 crisis elevated procurement costs. China has sought selective Hormuz access, partially mitigating disruption.
