Petrodollar Under Siege: The Iran War’s Hidden Battlefield

The Iran war is exposing the fragility of U.S. financial dominance as the Strait of Hormuz turns into a geopolitical pressure point. Disruptions to oil flows are accelerating challenges to the petrodollar system and dollar supremacy. What looks like strategic leverage may ultimately prove a costly Pyrrhic victory.

Although the de-dollarisation process has already been started by the aforementioned organisations, the dollar still maintains its hold on the international economy. But in recent months, two major events have augmented the process of de-dollarisation, which include the US-China reciprocal tariff war and the ongoing US-Iran war. The former clarified the fact that the US no longer holds the cards to exploit others, with Beijing becoming a peer competitor of the US. The latter exposes the dollar’s vulnerabilities, paving the way towards a global financial transition, which can ultimately lead to a change in the current world order.

US Achilles’ Heel in the Hormuz

When the US and Israel started a full-scale war against Iran on 28 February 2026, they were of the view that targeting the top leadership of the Iranian administration and energy centres would result in regime change. And, if Iran tries to choke off the Strait of Hormuz, it will be recovered with minimum losses. However, this is not the case. Iran, under its Mosaic doctrine, is now inflicting heavy blows on Israel and on the American infrastructure in Gulf states. By completely blocking world trade, Iran is using the Strait as leverage and is using this as an opportunity to either end or make maximum dents in the American economic monopoly in global politics.

Approximately 20 million barrels of oil and petroleum products are transported through the strait each day. Even the smallest disruption can have lasting negative effects on global commerce. Iran’s closure of this door not only interrupted maritime traffic; at its most physical choke point, it has put intense pressure on the structure of dollar dominance. Moreover, the international community is bilaterally dealing with Iran to allow its shipments to pass through the Strait safely, which it has allowed so far to various ‘friendly’ countries. However, to make matters worse for the US, Iran has allegedly asked nations to pay in Chinese yuan to get a permit to pass through it. This is where Iran is really pinching the US.

The era of petro-dollar is over

The role that BRICS wanted to play for so long is now being facilitated by the US-Iran war. For decades, the US has maintained its financial monopoly in the international arena by synchronizing its dollar with petroleum. Pursuing the economic warfare strategy, Iran is actually looking for alternatives to the dollar to challenge the petro-dollar regime. Following this conflict, it seems that Iran hopes to have a say in the creation of a new global order that will feature a multipolar financial system, with the dollar no longer serving as the sole currency that dominates the globe and the United States no longer having exclusive control over it.

In addition, on 18th March 2026, Israel targeted the world’s largest gas facility in Iran, known as South Pars, which is a gas lifeline for Iranian domestic needs. Although Israel has communicated the fact that the US was being informed of this attack, President Trump has denied US involvement on the pretext that this could exacerbate the already deteriorating energy situation globally and, resultantly, the war. Regarding the cessation of the hostilities, Iranian officials have explicitly stated, “Iran will end the war at a time of its own choosing and only if the conditions it has set are fulfilled. It will not allow Trump to determine the timing of the war’s end.” This statement clearly indicates that until and unless the pretense of US dominance is not crippled, Iran will not indulge itself in another tacit ceasefire, and will only end the war if all of Iran’s conditions are met.

The most important thing to note is that Iran does not want to just win the war against the US. Rather, it revolves around one scenario: a war of attrition. It just needs to cause sufficient economic disruption to force a U.S. retreat in such a way that a new normal is created in the Middle East, whereby the U.S. and Israel will be deterred from conducting any misadventure against the Iranian mainland, and the petro-dollar financial order would be disrupted. On the contrary, the US does not want to engage in prolonged warfare after its terrible experiences in Iraq, Syria, and most recently, Afghanistan. In spite of this, it is crystal clear that the US has miscalculated in two major ways.

One was the vague pre-war scenario with no clear objectives. If they successfully conducted a regime change by killing Khamenei, they had to have a solid replacement ready. Second, the US thought that killing the top tier of the Iranian leadership would embolden the anti-government protests, which would ultimately result in the toppling of the current regime. However, that wasn’t the case at all. It seems like the US is now caught between Iran and Israel. This war has become a bone of contention for the US – a matter of prestige and stature. No doubt, Iran cannot declare a complete victory, but the same goes for the US. The reason why Iran is not ending the hostilities lies in the fact that the US should realise that it has indulged in a war that is so costly that even victory seems like a significant loss – a pyrrhic victory.

The US hegemony over the entire international system is now under grave stress. The war against Iran has exposed the US vulnerabilities. The Hormuz dilemma has become a nightmare situation for the US, where a state that has no power compared to the US is controlling and dictating the global trade. The petrodollar arrangement, which became the crown jewel for the US, is now at its dying breaths. The end of the global minotaur is no longer just a debate; rather, it has now become a reality. The world now needs a parallel governance model, and to be honest, the process has started with its first visibility in the Middle East.
