If the United States becomes less able to defend the petrodollar system, the rivalry between Washington and Beijing may increasingly spill into the Middle East. Iran could become one of the main pressure points in that confrontation, not only because of its conflict with the United States and Israel, but also because of its growing strategic relationship with China.
A move away from the dollar in oil transactions would not cause the immediate collapse of the American currency. The dollar is still deeply embedded in global trade, banking, debt markets, and central bank reserves. However, if more energy transactions were settled in yuan, euros, gold, or local currencies, the long-term consequences for the United States could become significant.
Demand for dollars could gradually decline. American sanctions could become less effective. Financing the US public debt could become more expensive. The real risk is therefore not Iran acting alone, but Iran becoming part of a wider movement involving China, Russia, and possibly other major oil producers and importers.
The US-China confrontation should not be seen only as the possibility of a direct war between two superpowers. It is more likely to unfold through economic pressure, sanctions, proxy conflicts, cyber operations, attacks on infrastructure, technological competition, and influence over regional governments.
Iran could become one of the places where this indirect confrontation intensifies. China needs stable access to energy, while the United States wants to preserve its strategic influence, protect its allies, and maintain the strength of the dollar-based financial system. These interests are increasingly overlapping in the Gulf.
A military escalation involving Iran would also have consequences far beyond the region. Any serious disruption around the Strait of Hormuz could send oil prices sharply higher, damage global supply chains, increase inflation, and place pressure on economies in Europe, Asia, China, and the United States.
In practical terms, control over energy routes may become even more important than the currency in which oil is sold. A country may accept payment in yuan or euros, but if tankers cannot move safely through the Gulf, the entire global energy market is affected.
The Gulf states are therefore likely to continue balancing between the major powers. They may keep their security relationships with the United States while expanding trade, investment, and technological cooperation with China. This gives them more freedom, but it also places them at the center of an increasingly tense geopolitical competition.
For this reason, the Gulf countries should develop a stronger regional framework for diplomatic, economic, and cultural dialogue. Such a framework should include Arab states, Iran, and Israel, while avoiding both isolation and forced political normalization.
Israel should not be excluded, but neither should the other countries be pressured into agreements that lack public support or regional legitimacy. A more realistic starting point would be cooperation in areas where interests already overlap: energy security, maritime navigation, infrastructure protection, trade, education, water management, and cultural exchange.
The peace agreement between Egypt and Israel showed that governments can stop a war, but it also showed that a formal treaty does not automatically create trust between societies. Long-term stability requires more than signatures between political leaders. It requires communication between people, institutions, universities, businesses, and cultural communities.
Any large conflict in the Middle East would accelerate the division of the world into competing blocs. Countries would face increasing pressure to align either with the Western financial system, centered on the dollar, or with alternative systems supported by China and other emerging powers.
This could fragment global trade, payment networks, energy markets, technology systems, and military alliances. The result would not simply be a weaker petrodollar, but a more unstable and divided international order.
The central question is therefore larger than the future of the dollar. It is whether the Middle East will become a bridge between competing global powers or the main battlefield of a new era of proxy confrontation.
Without stronger regional communication and negotiation, Iran, Israel, and the Gulf states may become the front line of a conflict whose economic and political consequences would be felt across the entire world.
