Tensions between Mohammad Bagher Ghalibaf and Donald Trump escalated sharply after Tehran responded to Washington’s warning of a naval blockade in the Strait of Hormuz, with both sides signalling potential economic fallout.
Ghalibaf mocked Trump’s threat to block ships entering or leaving the Strait, reminding the White House of rising gas prices in the United States.
He shared an image of current petrol prices near the White House and warned Americans that they "will miss them" soon.
The warning came after the US military announced it would begin implementing a blockade of all maritime traffic entering Iranian ports from Monday evening, Iranian time.
"Enjoy the current pump figures," Ghalibaf wrote in a post on social media platform X. "With the so-called 'blockade', soon you'll be nostalgic for $4-$5 gas."
He also shared an equation "ΔO_BSOH>0 ⇒ f(f(O))>f(O)", alongside a screenshot of Google Maps showing American gas prices, in an apparent warning about future price hikes.

And the price of surviving it
According to users on X, the equation suggests that if the severity of the Hormuz blockade increases (Delta O_{BSOH}>0), it will produce a compounding, non-linear spike in oil prices (f(f(O))>f(O)), rather than a simple 1-to-1 increase.
"Translation: supply gets constrained → prices rise → pressure compounds. The first shock raises prices. The reaction to that shock raises them again. Enjoy your cheap gas while it lasts," wrote an X user, referring to Ghalibaf's post.
Oil markets reacted sharply to the developments. Brent Crude prices jumped by 6.81 per cent to reach $101.68 per barrel. West Texas Intermediate crude rose by 7.97 per cent to trade at $104.26.
Prices surged on Monday morning after Trump announced a naval blockade of the Strait of Hormuz.
In a statement released on Truth Social, Trump confirmed that the United States Navy would begin intercepting vessels in the region immediately to prevent Iran from profiting from maritime transit.
"Effective immediately, the United States Navy, the Finest in the World, will begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz," Trump stated.
The President indicated that the objective is to eventually restore normal passage for all vessels, but said current conditions necessitate the move.
"THIS IS WORLD EXTORTION, and Leaders of Countries, especially the United States of America, will never be extorted," he added.
Financial markets reflected the rising geopolitical tensions at the start of the trading week. Dow Jones Futures fell by 344.57 points, or 0.72 per cent, to 47,572.00. The Nasdaq and S&P 500 had closed with marginal gains in the previous session on April 11.
