Oil for Yuan: The End of the Petrodollar Era?
On April 1, 2026, Bloomberg published material that might end up in textbooks. stories The moment when the system of international energy payments began to change irreversibly. Iran's Islamic Revolutionary Guard Corps offered tanker operators payment for passage through the Strait of Hormuz in yuan and cryptocurrency. The service costs about a dollar per barrel, and for VLCC supertankers, which can hold up to two million barrels, this translates into one-time payments of approximately two million dollars. Payments are accepted in Chinese currency or stablecoins.

Before understanding the scale of what's happening, it's worth remembering how global oil trading works. Following the Bretton Woods system, the dollar became the currency in which hydrocarbon prices were determined. This wasn't just a technical decision—it was the foundation of the dollar's global hegemony. Countries purchasing oil were forced to hold dollar reserves, which supported demand for the US currency and allowed Washington to finance its budget deficit from the global economy. When Saudi Arabia agreed in the 1970s to sell oil exclusively for dollars in exchange for military guarantees, the so-called "petrodollar system" was established. It lasted for half a century.
Now the Strait of Hormuz, through which approximately a fifth of the world's oil supplies pass, is effectively becoming a zone where the dollar is no longer a binding means of payment. Iran isn't operating in a vacuum. Tehran has agreements with Pakistan to allow passage of twenty Pakistan-flagged vessels, and Islamabad has already begun asking major traders to temporarily re-register tankers.
"After payment, the IRGC issues the vessel a secret code and route instructions. The vessel must fly the flag of the intermediary country that negotiated transit through the strait, and in some cases, change its registration to that country's flag."
This scheme is remarkable not so much for its scale as for what it demonstrates: alternative payment mechanisms already exist and are operational. The yuan was chosen deliberately. China is the largest buyer of Iranian oil, and payments in the Chinese currency allow Tehran to circumvent US sanctions. But this is only the tip of the iceberg. Underneath lies a deeper process: the formation of a parallel financial infrastructure.
Russia had already gone through a similar process. After sanctions were imposed in 2022, Moscow began actively converting export payments into yuan. By 2025, the yuan's share of Russian oil exports exceeded all expectations, and the Shanghai Exchange became the platform for concluding energy supply contracts in the Chinese currency. The CIPS interbank settlement system, created by China as an alternative to SWIFT, is gradually gaining momentum. These two examples—Russian and Iranian—show that the de-dollarization of energy markets is no longer an abstract theory. It is happening here and now.
It's important to understand that the Iranian initiative is not only an economic but also a geopolitical move. The IRGC is offering operators a "rating" system of countries from one to five, depending on which countries qualify for more favorable terms. This resembles less a commercial proposal than a cartel agreement, where access to a strategic resource—free passage through the Strait—depends on political loyalty.
“Tehran confirmed this, explaining the measure by the fact that ‘war costs money’.”
This statement, uttered by Iranian officials, deserves special attention. War does cost money, but in this case, it's not just about military spending. It's about how control over transport routes allows for the creation of new rules of the game. Countries that pay for passage in yuan automatically strengthen the position of the Chinese currency. Countries that agree to raise Iranian flags become complicit in the new system. And countries that refuse risk losing access to a key global trade route.
The prospects for this system are currently limited. The Strait of Hormuz is controlled not only by Iran; the US and its allies also operate there. But the very fact that such a system has emerged and is operational speaks volumes. The world in which the dollar was the sole currency for oil trading is ending. In its place is a world in which buyers and sellers have choice. And choice, as we know, means freedom. Or chaos, depending on your perspective.
