Against the backdrop of China's increasingly consolidated position as the world's largest crude oil buyer, the Petroyuan has moved beyond a marginal concept, with its potential to challenge dollar dominance in global energy trade drawing widespread attention.
Since US President Nixon's 1971 announcement of the dollar's decoupling from gold, nations worldwide have been exploring new monetary systems and power balances. Former Libyan leader Gaddafi proposed a gold-backed pan-African currency, but this plan collapsed after his assassination in 2011. China, with its larger trade volume and broader market space, has demonstrated greater potential in promoting the Petroyuan.
In June 2017, the People's Bank of China and the Bank of Russia signed a memorandum of understanding aimed at promoting the use of the RMB in crude oil trade. The Petroyuan was officially launched in September of the same year. At that time, China had already become the world's largest crude oil importer, with imports reaching approximately 400 million tons in 2017. This massive demand provided a foundation for Beijing's attempt to challenge the dollar system.
The promotion of the Petroyuan carries significant political and economic considerations. For countries like Russia, Venezuela, and Iran, using RMB for oil transactions helps circumvent US sanctions. Simultaneously, oil-producing nations such as Saudi Arabia can reduce their reliance on the dollar system and lower the risk of facing US financial pressure. Therefore, the rise of the Petroyuan is closely linked to anti-sanction efforts and geopolitical power struggles.
Currently, the macroeconomic background supporting the RMB's strength in the international currency market is also becoming increasingly prominent. As of the end of February 2026, the RMB's exchange rate against the US dollar had risen to a nearly three-year high, standing at 6.831. Since the end of 2024, the RMB has appreciated by 6%. This growth is primarily attributed to China's substantial trade surplus. In 2025, China's trade surplus surpassed one trillion US dollars for the first time, reaching 1.18 trillion US dollars, a year-on-year increase of 20%. Despite a decline in exports to the US due to trade friction, China has successfully shifted its export focus to Southeast Asia and Europe, particularly in the automotive and solar product sectors, further consolidating its trade advantage.
