Following failed negotiations with the United States, Iran's parliament speaker Mohammad Bagher Ghalibaf issued a warning using a mathematical formula: ΔO_BSOH>0 ⇒ f(f(O))>f(O). This expression illustrates how a blockade of the Strait of Hormuz would lead to an initial rise in oil prices, which would then trigger further increases due to panic and supply chain disruptions. Ghalibaf emphasized that the damage from such a blockade would not be gradual but would escalate rapidly. He cautioned that Americans might soon long for current fuel prices, predicting they could rise to $4–$5 per gallon if the blockade is enforced. This warning follows US President Donald Trump's announcement of a blockade that would begin on Monday, affecting all vessels entering or leaving Iranian ports. The US Central Command stated that the blockade would apply to ships of all nations, although those traveling between non-Iranian ports would still be permitted to pass through the Strait of Hormuz. Iran's message highlights the potential for significant economic repercussions stemming from geopolitical tensions.
