Persian Gulf’s New Role in the New Monetary Order
The Strait of Hormuz is transforming from a "battlefield" into a global "monetary bridge of trade." For decades, the Strait of Hormuz has served as the most sensitive "thermometer" of global tension. This narrow strip of water, connecting the Persian Gulf to the Sea of Oman, is not just a geographical corridor; it is the main artery of the world economy. About a fifth of global oil consumption and a massive portion of liquefied natural gas (LNG) pass through it every day. However, for a long time, this region has been described as the "bottleneck of the energy market," a strategic choke point where Iranian threats of closure and the massive presence of the US Fifth Fleet created a fragile balance based on fear.
Today, in 2026, with attempts to establish a historic ceasefire between Iran and the US, this narrative is changing radically. The normalization of relations will not only bring silence to the guns, but is also rewriting the rules of global trade. In this new context, the role of the petrodollar — the system in which oil is traded exclusively in US currency — is being questioned as never before. For almost half a century, the petrodollar was a product of insecurity in the region. The Gulf countries accepted the dollar in exchange for US military protection against regional threats, mainly Iran. With the easing of this threat through diplomacy, the "security contract" that sustained the dollar's hegemony is now being shaken.
When the Strait of Hormuz ceases to be a conflict zone, it also ceases to be a monopoly of US interests. An open, secure, and coordinated Strait of Hormuz between regional powers (Iran and Saudi Arabia) gives the Gulf states unprecedented freedom to explore monetary alternatives. If the security of oil transportation no longer depends exclusively on American patrols, then payments for this oil also gain space to be made in currencies other than the US dollar. In this "new" trade "bridge," the Chinese yuan, the euro, or even central bank digital currencies are beginning to circulate alongside the dollar.
PETRODOLLARS – A BIT OF HISTORY
In the architecture of the post-World War II global economy, few mechanisms have exerted such a profound influence as the system known as the "petrodollar," born informally after the strategic agreements of the 1970s between the United States and Saudi Arabia. In 1974, in a world shaken by economic uncertainty and the ghosts of the Cold War, the United States was experiencing one of its most serious crises. The abolition of the gold standard in 1971 had left the dollar "naked," while the Arab oil embargo of 1973 had emptied the roads of America, Japan, and Europe of cars.
In this scene of chaos, uncertainty, and fear, one of the most ingenious and long-lasting agreements in modern history was born. In June 1974, the newly appointed US Treasury Secretary, William Simon, set off for Saudi Arabia on a mission that seemed impossible. Washington needed the dollar to remain the world's reserve currency, even though it was no longer tied to gold. On the other hand, Saudi Arabia was deeply concerned about regional destabilization, the Soviet threat, and the possibility of invasion by its neighbors.
The deal that was reached was simple in appearance, but monumental in its economic effects. Saudi Arabia would sell its oil exclusively in US dollars. In exchange, the US would provide unwavering military protection for the kingdom and high-tech combat equipment. Not only that, but there was another "invisible" condition: the Saudis would reinvest their huge profits back into the US by purchasing Treasury bonds.
This agreement created a perpetual cycle. Every country in the world that wanted to buy oil from Saudi Arabia (and later from all of OPEC, which followed suit) had to first acquire dollars. This created an endless demand for US currency. Even when the US economy faced difficulties, the dollar remained strong because the world was "thirsty" for energy, and the path to energy ran through the dollar.
This system worked like clockwork for 50 years. But in 2026, the narrative is changing. When we talk today about a ceasefire with Iran and the normalization of the Strait of Hormuz, does this not also mean striking at the main pillar of this agreement: military protection? If Saudi Arabia and its neighbors no longer feel threatened by Iran and no longer need "exclusive" American defense as in 1974, they have less incentive to keep oil tied only to the dollar. Today, when China is the largest buyer of Saudi oil, the question being asked in Jeddah is no longer "how to protect ourselves," but "why not get paid in yuan?"
ANALYSIS OF THE PEACE ACT AND CURRENCY DIVERSIFICATION
Since 1974, the role of the US military in the Gulf has been that of a global "insurance company." The Gulf states accepted the dollar as their sole currency because only the US could guarantee that their oil would pass safely through Hormuz, despite Iranian threats. Will an expected deal with Iran — whose final content remains unknown — leave the massive military presence (such as the Fifth Fleet in Bahrain) unchanged, or render it less necessary? If the latter occurs and the risk of blocking the strait disappears through diplomacy, the "price" that Gulf states have paid (loyalty to the dollar) loses much of its strategic value.
With a ceasefire — if achieved — the security of the sea passage is expected to shift toward a regional arrangement in which Iran and Saudi Arabia cooperate. The consequence is clear: the US military loses its role as the sole "gatekeeper" of oil, paving the way for countries like China to demand that their purchases be made in yuan, since the military risk is reduced.
The Gulf countries have long been among the largest buyers of American weapons, paying for them in petrodollars. This created a closed cycle: oil sold in dollars financed the purchase of American arms, which in turn guaranteed security. A lasting peace with Iran would reduce the need for emergency purchases of missile systems and advanced aircraft. With fewer multibillion-dollar defense contracts, Gulf countries would have less need to hold massive dollar reserves, encouraging diversification into other currencies, gold, or even cryptocurrencies.
With the lifting of sanctions and normalization of relations, Iran would cease to be perceived as a "potential disruptor" of the petrodollar system through sabotage and instead become integrated into global trade. Here lies one of the key paradoxes of the current moment: are we heading toward a post-petrodollar world, or simply toward a coexistence of currencies?
THE FALL OF THE MONOPOLY, BUT NOT THE KING
For five decades, the dollar was not just a currency; it was the "native language" of world trade. If you wanted to buy oil in Riyadh, machinery in Berlin, or wheat in Buenos Aires, you had to go through Washington. This monopoly rested on two pillars: trust in American stability and the need for military security in the Gulf. Today, the second pillar — security — is weakening.
However, this does not mean that the dominance of the dollar will disappear. Rather, it is shifting from the role of an "absolute dictator" to that of a "prime minister in a coalition government." What is emerging is what experts call a "multi-currency world."
What we are witnessing is not the "death of the dollar," but the rise of alternatives that were once unimaginable. Imagine an oil market where Saudi Arabia accepts the Chinese yuan for infrastructure payments, the United Arab Emirates uses the Indian rupee for food trade, and Iran trades its gas with Europe through euro-based mechanisms.
This is "coexistence." In this new world, the dollar remains the most liquid and reliable currency for capital markets, but it is gradually losing its exclusivity over commodities. This process is often described as the "de-dollarization of the margins." While the core of the system remains tied to the dollar due to the depth of American financial markets, the "arteries" that supply the world with energy are diversifying.
The term "post-petrodollar" may be accurate if it refers to the end of the era in which the dollar was the only means of purchasing energy. In 2026, blockchain technology and central bank digital currencies (CBDCs) are making it easier to bypass the SWIFT system, which has long served as a key instrument of US financial influence. Payments for energy cargoes no longer necessarily need to pass through correspondent banks in New York; they can be settled more directly through alternative systems.
However, coexistence also brings complexity. A world with multiple currencies is one with higher transaction costs and greater exchange-rate uncertainty. For the Gulf countries, this represents a delicate balancing act. They seek to maintain the dollar as a store of value while increasingly using other currencies for trade, especially with major partners such as China, India, and the BRICS countries.
Conclusion: A New "Hybrid" Order
There will not be a day when the world wakes up and the dollar is worthless. Instead, what may emerge over time is a gradual transformation, where the dollar coexists with the yuan, the euro, and other assets in a system where no single power can fully dominate global finance.
The normalization of the Strait of Hormuz symbolizes the beginning of this shift. When energy flows freely without the shadow of military conflict, the currency used to purchase it becomes primarily a medium of exchange rather than a tool of geopolitical control.
The post-petrodollar world is not a world without dollars, but a world in which the dollar is first among equals. In this context, the role of the BRICS countries gains particular importance. Efforts by China and Russia to promote energy trade in their national currencies are part of a broader push toward a more multipolar monetary order.
In conclusion, the petrodollar remains a central pillar of the global economy, but no longer an uncontested one. It is entering a phase of transition, where globalization, geopolitical competition, and financial innovation are reshaping the balance of power. The key question is not whether the petrodollar will disappear, but to what extent and at what pace it will adapt to an increasingly multipolar world.
