Deutsche Bank has warned that the current Iran-related geopolitical crisis could become a meaningful turning point for the global energy trade, especially if more oil flows through the Strait of Hormuz begin to settle in Chinese yuan rather than U.S. dollars. In a March research note cited in the source material, strategist Mallika Sachdeva described the conflict involving the United States, Israel, and Iran as a potential “perfect storm” for the petrodollar system.
The bank’s argument is not that the dollar is on the verge of sudden collapse. Instead, it points to a slower but potentially important structural shift: if yuan-based oil settlements gain momentum in one of the world’s most critical energy corridors, the foundations of dollar dominance in global trade and reserves could gradually weaken.
Hormuz at the Center of the Currency Debate
The Strait of Hormuz is one of the most strategically important maritime chokepoints in the world, handling roughly one-fifth of global oil and gas flows. According to the report, since the conflict escalated in late February 2026, Iran has reportedly pressured tankers passing through the strait to settle oil transactions in yuan. Deutsche Bank characterized this development as a possible inflection point, not because it immediately changes the global system, but because it could signal that currency preferences in energy trade are becoming more openly contested under geopolitical stress.
The source material states that since late February, tankers linked to China have moved at least 11.7 million barrels through the area, with some vessels reportedly turning off tracking systems to avoid detection. It also notes that discussions were reported with at least eight non-Middle Eastern countries about conducting oil trade in yuan as part of efforts to secure safe transit.
Why China Matters in This Shift
China is already the largest buyer of Iranian oil and has spent years promoting yuan invoicing in energy and cross-border trade. The article points to mechanisms such as mBridge as part of Beijing’s broader effort to internationalize the yuan. In that context, Iran’s reported preference for yuan settlement is not an isolated policy move. It fits into a wider trend in which sanctioned or politically exposed oil producers seek alternatives to the dollar-based financial system.
That is one reason Deutsche Bank sees the current crisis as more than a temporary wartime distortion. If geopolitical pressure, sanctions, and shipping risk increasingly encourage non-dollar settlement, then the yuan’s role in commodity trade could expand from niche bilateral use toward something with broader strategic significance.
The Petrodollar’s Historical Strength—and Its New Test
The petrodollar system dates back to 1974, when Saudi Arabia agreed to price oil exports in U.S. dollars in exchange for U.S. security guarantees. That arrangement created durable global demand for dollars and reinforced the dollar’s role as the dominant reserve currency. Even as energy trade patterns shifted over time, the core structure remained intact.
Today, however, the report notes a new reality: Saudi Arabia now sells roughly four times more oil to China than to the United States, yet the broader dollar-centered architecture still survives. That resilience is one reason Deutsche Bank does not forecast an outright break. Dollar dominance rests not only on oil pricing, but also on deep financial markets, liquidity, institutional trust, and global network effects that are extremely difficult to displace quickly.
Still, the bank argues that wars and sanctions can expose weaknesses in long-standing systems. Sachdeva’s framing suggests that the Iran conflict may become a historical stress test for the petrodollar regime rather than an instant overthrow of it.
Sanctioned Oil Is Already Trading Beyond the Dollar
A major part of Deutsche Bank’s warning comes from what is already happening outside the conventional dollar system. According to the source article, sanctioned oil from Iran and Russia now accounts for about 13 million barrels per day, or roughly 14% of global supply. Much of that volume has been traded outside the dollar framework for years.
In that sense, the conflict does not create a non-dollar energy channel from scratch. It broadens and intensifies one that already exists. If additional producers decide that routing sales outside the dollar system offers political or commercial advantages, then the long-term effect could be cumulative. Deutsche Bank specifically notes that countries such as Russia and Venezuela may have stronger incentives to pursue energy sales beyond dollar settlement if regional instability persists and U.S. security guarantees appear less credible.
Risks for Markets and Reserve Allocation
The report also highlights broader financial risks. Gulf economies absorbing the damage of conflict could sell dollar-denominated assets. Sovereign wealth funds and central banks may accelerate reserve diversification if confidence in the existing U.S.-anchored security architecture weakens. This matters because the dollar’s dominance is reinforced not only by trade invoicing, but by reserve management and capital allocation decisions across the world.
At the same time, the article places the issue within a larger de-dollarization trend. BRICS countries have been pushing for trade arrangements that bypass the dollar. Russia and China had already signed yuan-based energy contracts before the current conflict. Central banks globally have been increasing holdings of gold and non-dollar reserve assets. From Deutsche Bank’s perspective, the Iran crisis may be accelerating a process already underway rather than creating a wholly new one.
Oil Prices Are Sending a Warning Signal
Commodity markets have reflected these concerns. West Texas Intermediate crude recently traded above $90 per barrel, underscoring how seriously traders are treating risks tied to the Strait of Hormuz. The source material also says the yuan showed moderate strength in some sessions, although analysts stressed that no decisive structural shift had yet been confirmed.
That caution is important. Past oil shocks, including those in the 1970s, ultimately reinforced the dollar rather than undermined it. Higher oil prices can increase global demand for dollars, especially if commodities remain widely priced in the U.S. currency. For that reason, not every geopolitical shock translates into a sustained loss of dollar power.
A Structural Story, Not an Immediate Regime Change
The key takeaway from Deutsche Bank’s analysis is one of gradualism. The bank is not calling for the end of the dollar era. It is warning that the current conflict could leave behind a structural legacy if market participants become more comfortable settling strategic energy trade in yuan. That would matter because global reserve systems often evolve slowly, through repeated adjustments in settlement habits, invoicing practices, and asset allocation.
Whether the trend deepens depends heavily on what happens next in the region. A de-escalation could reduce immediate pressure and slow the move toward alternative settlement. But if the conflict persists, and if yuan-denominated oil flows through Hormuz continue to expand, the episode may be remembered as a significant test of the petrodollar’s durability.
For now, Deutsche Bank appears to be watching one metric above all others: the scale of yuan-denominated oil flows through the Strait of Hormuz. In its view, that may become one of the clearest indicators of whether the world is merely experiencing another geopolitical oil shock—or the early stages of a more consequential shift in the monetary architecture of energy trade.
