Recent reports indicate that Iran is requiring oil tankers passing through the Strait of Hormuz to pay for passage in yuan, a direct challenge to the US petrodollar system that has underpinned American financial and geopolitical power since the 1970s. This move by Tehran comes amid escalating military tensions between Iran and the US-Israel alliance, and reflects a broader trend of de-dollarization as China promotes the internationalization of its own currency, the yuan.

Why it matters

The petrodollar system, established through a 1974 deal between the US and Saudi Arabia, has allowed the US to sustain massive debt and military spending by ensuring global demand for the dollar. Iran's actions in the Strait of Hormuz threaten to undermine this system, potentially limiting Washington's ability to wield economic sanctions and its expansive military budget, which are central to American global hegemony.

The details

Iran is reportedly conditioning the passage of oil tankers through the Strait of Hormuz, a critical maritime chokepoint, on payment in yuan rather than US dollars. This represents a direct challenge to the petrodollar system that has underpinned American financial and geopolitical power since the 1970s. Under the petrodollar arrangement, Gulf oil producers agreed to sell their crude exclusively in dollars in exchange for US security guarantees. This helped sustain global dollar demand and allowed the US to run large deficits. Iran's move comes amid escalating military tensions with the US and Israel, and reflects a broader trend of de-dollarization as China promotes the internationalization of its own currency, the yuan.

  • In 2015-2018, China launched the Cross-Border Interbank Payment System (CIPS) and began trading oil contracts in yuan on the Shanghai International Energy Exchange, laying the groundwork for the petroyuan.
  • By the end of 2023, the Chinese energy company CNPC conducted its first oil transaction in digital yuan through the Shanghai Petroleum and Natural Gas Exchange.
  • Recent unofficial reports have indicated that Tehran is now conditioning the passage of oil tankers through the Strait of Hormuz on payment in yuan.

What they’re saying

“The decline of the petrodollar in the Gulf is not a matter of if it will happen, but when, and that when is approaching faster than most believe.”

“The financial innovations promoted by China offer oil producers alternatives that are not only viable but also potentially superior to dollar-based settlement channels, which are particularly vulnerable to disruptions caused by technological advances.”

What’s next

The military tension in the Strait of Hormuz is expected to continue, as Iran seeks to leverage its control over this strategic chokepoint to promote the adoption of the petroyuan. This could further erode the dominance of the US dollar in global energy trade, with significant implications for American financial and geopolitical power.

The takeaway

The rise of the petroyuan represents a fundamental challenge to the US-dominated petrodollar system that has underpinned American global hegemony since the 1970s. While the immediate collapse of the petrodollar is unlikely, the gradual erosion of its dominance could severely degrade the US's ability to sustain its expansive military spending and economic wars through the weaponization of the dollar.
