Iran's parliament speaker, Mohammad Bagher Ghalibaf, mocked US President Donald Trump's threat to block ships in the Strait of Hormuz, warning that Americans could soon face much higher gas prices. Ghalibaf shared a post on social media, highlighting current petrol prices near the White House and suggesting that the impending blockade would lead to nostalgia for prices around $4-$5 per gallon. The US military, through US Central Command (CENTCOM), announced it would enforce a blockade on all maritime traffic to Iranian ports starting Monday at 10 AM EDT (5:30 PM Iranian time), allowing only non-Iranian vessels to transit the Strait. Following the announcement, US oil prices surged above $100 per barrel, with West Texas Intermediate (WTI) rising to $104.50. The backdrop to these tensions includes failed ceasefire talks in Islamabad, where US Vice President JD Vance and Iranian officials could not reach an agreement, leaving both sides pessimistic about future negotiations.
