Russia-Ukraine War 2026- How is China using the yuan to get around Iran sanctions?
- Chinese refiners like Hengli Petrochemical restructured their corporate ownership to hold Iranian crude through state-adjacent entities and settle purchases in yuan, bypassing dollar-clearing systems that give the US Treasury visibility needed for sanctions enforcement.Source: OFAC / Lowdown Iran briefing
- Can the US sanction companies that use yuan to buy Iranian oil?
- The US can impose secondary sanctions on non-US companies that buy Iranian oil regardless of currency, but yuan settlement removes dollar-ledger visibility, making detection and enforcement harder. The 24 May 2026 expiry of General License V tests whether OFAC pursues Hengli after the wind-down.Source:
- What is the petrodollar and why does China want to undermine it?
- The petrodollar system means global oil trade is denominated in US dollars, giving the US leverage over international finance and enabling sanctions. China promotes yuan-denominated oil settlement to reduce that leverage and internationalise the renminbi.
Background
The Chinese yuan (renminbi, CNY) is China's official currency, issued by the People's Bank of China. Its use in international oil settlements has expanded significantly since 2022 as Beijing and its trading partners have sought to reduce dependence on dollar-denominated transactions, particularly following Western sanctions on Russia.
In the context of the 2026 Iran war and associated sanctions architecture, the yuan's role became structurally significant on 29 April 2026 when Hengli Petrochemical restructured its Singapore trading Arm to insulate physical refining operations from OFAC reach. Hengli confirmed it would continue settling oil procurement in Chinese yuan, explicitly bypassing dollar-rail payment systems. The restructuring transferred 95% of the Singapore Arm to a Chinese local government entity, retaining only a 5% stake to maintain technical legal continuity. The General License V wind-down expires 24 May 2026, after which OFAC enforcement options theoretically tighten, though dollar-bypass settlement makes secondary sanctions harder to enforce.
The yuan's role as an Iran-sanctions bypass mechanism is limited by Beijing's own exposure: Chinese state-adjacent entities that process sanctioned Iranian crude remain vulnerable to US secondary sanctions if they maintain any dollar-clearing relationships. The Hengli restructuring represents a structural bet that Beijing will protect state-adjacent refining operations from OFAC reach, and that yuan settlement strips the US of the dollar-ledger visibility needed for enforcement.
