Iran and China Deploy Yuan Toll Payments in Strait of Hormuz to Erode US Dollar Dominance
Amid the paused US‑Israel‑Iran conflict, Tehran and Beijing have begun charging transit fees in yua…
The temporary cease‑fire in the US‑Israel‑Iran war has given Iran and China a strategic opening to challenge the US dollar’s supremacy in global finance. Both nations share a common objective: to reduce reliance on the greenback, especially in the oil sector where, according to a 2023 JP Morgan estimate, roughly 80% of transactions are settled in dollars.
In a practical step toward this goal, Iran’s de‑facto toll‑booth system in the Strait of Hormuz—a chokepoint that handles about one‑fifth of the world’s oil and LNG shipments—has started accepting transit fees in Chinese yuan. Lloyd’s List reported that at least two vessels had already paid in yuan by March 25, and China’s Ministry of Commerce later acknowledged the reports on social media.
Iran’s embassy in Zimbabwe even called for the introduction of a “petroyuan” to the global oil market, underscoring the political symbolism of the move. While Tehran pledged to guarantee safe passage for two weeks under a US‑brokered cease‑fire, Beijing declined to comment.
Harvard economist Kenneth Rogoff told Al Jazeera that Iran’s actions serve a dual purpose: they “poke a thumb in the United States’s eye” and provide a practical alternative to dollar‑based sanctions. Rogoff added that Iran’s shift to yuan aligns with China’s broader effort to redenominate trade among BRICS nations.
For both countries, the yuan offers a way to sidestep US sanctions and lower transaction costs. Their trade relationship, cemented by a 25‑year strategic partnership signed in 2021, sees China buying over 80% of Iran’s oil—often at discounted rates—while Iran imports Chinese machinery, electronics, chemicals, and industrial components.
Data from Kpler and TankerTrackers indicate that, despite the conflict, Iran’s oil exports to China have remained near pre‑war levels, ranging between 12 million and 13.7 million barrels in the first two weeks of hostilities.
China’s ambition to elevate the yuan is long‑standing. President Xi Jinping, in a 2024 address, expressed hope that the yuan would become a global reserve currency. Yet significant hurdles remain: the yuan is not freely convertible due to strict capital controls, and the Chinese financial system is perceived as opaque, limiting broader adoption.
According to the IMF, the dollar still dominated global foreign‑exchange reserves at 57% last year, far ahead of the euro’s 20% and the yuan’s modest 2%. Cross‑border trade settled in yuan rose to 3.7% in 2024, up from under 1% in 2012, per S&P; Global—an encouraging but limited shift.
Natixis chief economist Alicia Garcia‑Herrero cautioned that the Strait of Hormuz experiment adds only “incremental pressure” and that a true “de‑dollarisation” would require Gulf states, which have priced oil in dollars since the 1970s in exchange for US security guarantees.
European analyst Hosuk Lee‑Makiyama highlighted that China’s ability to supply Iran with essential goods makes the yuan a viable alternative, a dynamic not possible for Europe or Japan. He described China as the closest the world has seen to a “manufacturing one‑stop shop.”
Consultancy founder Dan Steinbock echoed that while the dollar’s supremacy is unlikely to crumble overnight, the gradual increase in yuan usage could “chip away” at US dominance in specific sectors over time.
Rogoff concluded that the long‑term impact hinges on the war’s outcome. If Iran and China emerge stronger, many countries may diversify away from the dollar to avoid US‑imposed financial constraints. Conversely, a decisive US victory could reinforce dollar hegemony for the foreseeable future.
