March 26, 2026 – Deutsche Bank warns that Iran’s demand for yuan-based oil payments at the Strait of Hormuz could mark a turning point for the petrodollar system and accelerate de-dollarization in global energy trade.
In Summary
Deutsche Bank’s March 2026 research note warns that the Iran war is “a perfect storm for the petrodollar.”
Iran demands a yuan-denominated settlement for tanker passage through the Strait of Hormuz, which carries 20% of global oil.
Oil prices surged from ~$60 in January to a peak of $126 per barrel. Brent crude recently traded near $109.
The yuan holds just 2% of global reserves, compared with 57% for the dollar, but the yuan-based oil trade is accelerating.
Sanctioned Iranian and Russian oil totals ~13 million barrels/day (14% of global supply), mostly traded outside dollar rails.
The Dallas Fed estimates a one-quarter Hormuz closure could cut global GDP growth by 2.9 percentage points.
The Petrodollar Under Pressure
The petrodollar system has anchored the U.S. dollar since 1974. Saudi Arabia agreed to price oil exclusively in dollars. In return, Washington offered security guarantees. That deal created persistent global demand for the greenback.
Now, the Deutsche Bank March 2026 research note warns that this foundation is cracking. Strategist Mallika Sachdeva calls the Iran conflict “a perfect storm for the petrodollar.”
Hormuz: The Critical Chokepoint
The Strait of Hormuz carries roughly 20 million barrels per day. That represents 20% of global petroleum consumption. About 84% of these flows head to Asian markets.
Iran effectively closed the Strait on March 2, 2026. It now permits limited tanker passage. However, there is a condition. Reports from CNN via IranWire confirm Tehran demands yuan settlement for safe transit.
Oil prices surged from around $60 in January to above $126 at their peak. Brent crude recently traded near $109 per barrel. The crisis is the largest energy disruption since the 1970s.

Yuan vs. Dollar: The Structural Shift
China is Iran’s largest oil buyer. Beijing has paid in yuan for Iranian crude for years. The new Hormuz condition formalizes this arrangement. It also extends yuan settlement to non-Chinese buyers seeking safe passage.
At least 11.7 million barrels moved through Chinese-linked tankers since late February. Discussions with eight non-Middle Eastern countries on yuan-based transit have been reported.
Key Data Point: The yuan accounts for just 2% of global foreign-exchange reserves. The dollar holds 57%. Despite this gap, the yuan-denominated oil trade is accelerating. Roughly 20% of global oil trade was denominated in non-dollar currencies as of 2023. (Asia Times)

De-Dollarization Momentum Builds
The trend predates this crisis. BRICS nations have pushed non-dollar trade agreements for years. Russia and China settled energy contracts in yuan before the conflict. Saudi Arabia now accepts yuan for oil sales.
Sanctioned Iranian and Russian oil totals roughly 13 million barrels daily. That represents about 14% of the global supply. Most of this volume already trades outside dollar rails.
Dollar’s Durability vs. Erosion Risk
Deutsche Bank does not predict an immediate dollar collapse. The dollar’s deep liquidity and network effects remain unmatched. Past oil shocks have even reinforced the dollar’s strength.
However, Sachdeva frames this war as a historic stress test. Gulf economies may unwind dollar-denominated holdings. Sovereign wealth funds could diversify faster. The Dallas Fed estimates a one-quarter Hormuz closure could lower global GDP growth by 2.9 percentage points.
The conflict’s long-term monetary impact may outlast its military phase. Whether it produces permanent structural damage depends on duration and de-escalation. Markets remain cautiously optimistic. But the pressure on the petrodollar is already being applied.
