The war involving Iran and disruptions in the Strait of Hormuz are reshaping global oil trade in ways that could strengthen China’s currency in energy markets. While the long‑standing dollar‑based oil system is not collapsing, the crisis is accelerating changes already underway—particularly the gradual expansion of yuan‑denominated oil transactions, often called the petroyuan.
Three forces are driving this shift: disrupted shipping routes, China’s growing role as the most reliable large oil buyer, and the strategic advantage created by its enormous oil stockpiles.
The Strait of Hormuz Shock to Global Oil Trade
The Strait of Hormuz is one of the most critical chokepoints in the global energy system. Roughly one‑fifth of the world’s oil normally passes through the narrow waterway connecting the Persian Gulf to global markets.
During the current conflict, Iranian military actions—including threats, ship attacks, and mining operations—have severely disrupted shipping through the strait. Some commercial carriers paused operations after attacks on merchant vessels in early May.

What should I do next in practice?
China’s massive oil reserves—estimated near 1.4 billion barrels—give Beijing leverage during supply shocks, allowing it to buy strategically while other countries scramble for supply.
Despite these risks, Chinese-linked oil tankers have continued attempting to move crude through the strait. Maritime tracking data showed a Chinese supertanker carrying nearly 2 million barrels of Iraqi crude attempting transit on May 13. A week later, two Chinese supertankers carrying about 4 million barrels reportedly passed through the waterway.
That pattern matters because it shows who can still operate when the market is under stress. In crisis conditions, the companies and countries able to buy, insure, ship, and finance cargoes gain influence over how the oil trade functions.
Crisis Conditions Are Boosting Yuan Oil Payments
Periods of geopolitical disruption often accelerate changes in financial infrastructure. In this case, instability around Hormuz has increased the attractiveness of yuan settlement for oil trades.
Some reports indicate demand for yuan rose after Iran began accepting payments in China’s currency for certain shipments navigating the strait, making settlement outside the dollar system more practical in wartime conditions.
However, there is an important caveat. Despite speculation about a “yuan‑only corridor” through Hormuz, no official rule requiring oil cargoes to be settled in yuan has been publicly confirmed by either Iranian or Chinese authorities.
That means the shift toward the petroyuan is happening incrementally through trade behavior, not through a formal replacement of the dollar system.
The Petroyuan vs. the Petrodollar
For decades, the global oil market has been closely tied to the U.S. dollar—a structure often called the petrodollar system. Most crude oil has historically been priced and settled in dollars, reinforcing the currency’s dominance in global trade and finance.
China has spent years building alternatives designed to internationalize the renminbi. These efforts include yuan‑denominated oil futures and settlement mechanisms aimed at reducing reliance on dollar‑based financial networks.
The Iran conflict strengthens that effort because:
sanctioned producers are more willing to accept alternative currencies
sanctions risk makes dollar settlement less attractive for some trades
Chinese banks and shipping networks provide a parallel channel for transactions
Still, analysts widely agree that the dollar remains the dominant currency in global energy markets, and any transition away from it will likely be gradual rather than sudden.
China’s Strategic Oil Reserves: A Hidden Advantage
China entered the crisis with an unusually strong position in oil security.
According to estimates from the U.S. Energy Information Administration, China held the world’s largest strategic oil inventories as of December 2025, ahead of the United States and Japan. Those reserves reached nearly 1.4 billion barrels after large stockpiling in 2025, when China added roughly 1.1 million barrels per day to strategic inventories.
Large reserves give Beijing several strategic advantages during an oil shock:
Reduced urgency: China can draw on reserves instead of rushing into panic buying during price spikes.
Market leverage: With time on its side, China can negotiate better deals with exporters.
Sanctions flexibility: Producers under sanctions may accept yuan settlement to secure access to the Chinese market.
In other words, stockpiles function as both an energy security buffer and a geopolitical bargaining tool.
A Fragmenting Oil Market
The immediate result of the conflict is not the collapse of the petrodollar but a more fragmented global oil system.
Several overlapping networks are emerging:
traditional dollar‑based oil trade
sanction‑affected oil corridors involving China, Iran, and Russia
alternative settlement channels using yuan and other currencies
If more cargoes are financed by Chinese banks, transported by Chinese‑linked fleets, and purchased by China as buyer of last resort, the yuan’s role in oil trade could steadily expand—even if benchmark pricing systems like Brent and WTI remain dollar‑denominated.
The “Golden Window” for Renminbi Internationalization
Geopolitical crises often accelerate financial change. The disruption around the Strait of Hormuz may represent a rare opportunity for the renminbi to gain practical global use.
The key shift is not ideological but operational. In unstable markets, traders prioritize whatever system allows shipments to move and payments to clear. If yuan settlement continues proving useful in those conditions, its role in energy trade could grow significantly over time.
For now, the global oil system is not switching from petrodollars to petroyuan overnight. But the Iran war is showing how quickly the structure of energy finance can start to evolve when the world’s most important shipping lane becomes a battlefield.
