Iran has sharpened its rhetoric against the United States as tensions rise over the planned maritime restrictions near the Strait of Hormuz, with Mohammad Bagher Ghalibaf warning that American consumers could soon feel the impact at fuel pumps.

In a pointed message aimed at Donald Trump, Ghalibaf suggested that current petrol prices in the US may not last, arguing that the proposed blockade targeting Iranian ports could trigger a sharp and potentially compounding rise in global oil costs. Sharing images of fuel prices near Washington, he told Americans to "enjoy" current rates while they last.

The remarks come as the US military prepares to implement a blockade on vessels entering and leaving Iranian ports, following the collapse of recent negotiations between Washington and Tehran. While US officials have clarified that transit through the Strait of Hormuz for non-Iranian trade will remain open, the move has heightened concerns over supply disruptions in one of the world's most critical oil corridors.

Ghalibaf reinforced his warning with a cryptic mathematical expression, interpreted by observers as a signal that any tightening of restrictions could lead to a non-linear spike in oil prices-where initial increases are amplified by market reactions and supply constraints.

Markets have already begun responding to the growing uncertainty. Oil prices surged sharply after the announcement, with benchmark crude rates climbing amid fears of constrained supply. Asian stock indices also showed volatility, reflecting broader investor concern over escalating geopolitical risks.

The standoff follows failed talks in Pakistan, where both sides were unable to bridge key differences, particularly over Iran's nuclear programme and regional security issues. With diplomacy stalled, the focus has now shifted to economic and strategic pressure, raising the stakes for global energy markets.

As both Washington and Tehran dig in, the confrontation is increasingly being framed not just in military or political terms, but in its potential to directly impact everyday costs-especially fuel prices-for consumers far beyond the region.
