Japan Is Paying Iran in Chinese Yuan for Permission to Use the Strait of Hormuz

Iranian FM Araghchi told Japan's Kyodo News on March 21: "We didn't close the strait. It's open." He offered safe passage for Japanese ships: "All they need to do is contact us to discuss how this route will be." The strait is "closed only to ships belonging to our enemies, countries that attack us."

Japan reportedly agreed to pay in Chinese yuan for transit rights. One tanker reportedly paid $2 million. The IRGC administers a "vetting system" where vessels submit ownership and cargo destination details in advance. Countries with approved transit as of March 21: China, India, Pakistan, Iraq, Malaysia, and now Japan.

An American treaty ally. Paying an American adversary. In a rival currency. For passage through a waterway the US Navy is supposed to keep open. The nation-states piece described state sovereignty being "routed around." This is the routing made literal: Japan routes around American security guarantees because those guarantees aren't functioning.

The de-dollarization dimension is the structural story. Every barrel settled in yuan through Hormuz is a precedent. Iran is using Hormuz access as a geopolitical loyalty test, splitting the US-allied coalition into countries willing to pay Tehran's toll and countries that refuse on principle. The coalition is splitting along the pay-or-refuse line.

South Korea's 76.2% nuclear weapons support and Takaichi's Third Principle revision are the downstream consequences. When American security guarantees prove conditional on American attention (which is finite and currently consumed by Iran), allies seek autonomous solutions. Nuclear weapons are the ultimate autonomous solution.

FAQ

Is Japan violating the alliance by paying Iran?

The US-Japan security treaty does not prohibit commercial transactions with Iran. Japan has historically maintained economic relationships with countries the US sanctioned. The yuan payment is legally permissible but diplomatically humiliating for Washington. The US cannot simultaneously fail to keep Hormuz open and criticize allies for negotiating their own access.

Will more countries pay for Hormuz transit?

Yes. South Korea is reportedly in discussions. European countries are evaluating. The IRGC's vetting system creates a de facto toll regime that will expand as more countries calculate that paying is cheaper than waiting for the US to clear the mines. Each country that pays legitimizes Iran's sovereignty claim over the strait.

Does this help China strategically?

Enormously. Every transaction in yuan through Hormuz builds the infrastructure for non-dollar trade settlement. China doesn't need to force de-dollarization. It needs enough countries to use yuan often enough that the pathways become routine. The Iran war is providing that usage at scale.
