March 12 was defined by a single statement: Iran's new Supreme Leader Mojtaba Khamenei publicly demanded the Strait of Hormuz remain closed, called for all US military bases in the region to be attacked, warned that new fronts are being studied, and vowed vengeance. Iran's security chief Larijani simultaneously told Trump directly that "quick victory is impossible" and vowed to "not relent until making you sorry." CENTCOM revealed the conflict's full scale: approximately 6,000 targets struck, 60+ ships destroyed. Oil approached $100 a barrel, the USO ETF neared a 7-year high, and Goldman Sachs raised its US inflation forecast. Half the world's LNG tanker charter fleet sat stranded in the Persian Gulf. By evening, Netanyahu had held his first press conference declaring conditions for regime change in Iran, Brent crude had settled above $100 for the first time since 2022, and the New York Times reported US officials confirm Iran is actively mining the Strait of Hormuz — directly contradicting Treasury Secretary Bessent's denial hours earlier.

Bahrain confirmed Iran targeted fuel tanks at the Muharraq facility. Oman evacuated ships from Mina Al Fahal oil terminal. UAE reported a new Iranian missile and drone wave. Most significantly, the Wall Street Journal reported that US officials say Iran has laid approximately 10 mines in the Strait of Hormuz — a report that would gain further credibility throughout the day as the UK Defence Secretary cited mounting evidence.
Morning — economic damage deepens: Goldman Sachs raised its US inflation forecast and cut its 2026 growth outlook, explicitly naming higher oil prices from the Iran conflict as the top economic risk. Energy Secretary Chris Wright said the Navy is not yet ready for Hormuz tanker escorts, but possible by month-end. US gasoline hit $3.60 per gallon — up 35 cents in a week. Diesel is above $5 in eight states, with California at $6.16. Air France-KLM announced it is raising long-haul ticket prices.

Afternoon — Khamenei speaks: Supreme Leader Mojtaba Khamenei's statement, delivered through Iranian state TV, was the defining moment of the day. He demanded Hormuz stay closed, called for attacks on all US bases in the region, warned new fronts are under study, and vowed vengeance. The IRGC Navy commander posted on X pledging "the most severe blows." Iran fired a new wave of missiles at Israel. About 20 LNG carriers — half the global charter fleet — remained stranded in the Persian Gulf. Stocks fell to session lows. Iran's security chief warned the region could face a blackout if Iran's power grid were destroyed.
Late afternoon — UK: mines confirmed, Norway: Hormuz banned: UK Defence Secretary Healey told Parliament that evidence mounts Iran has started mining Hormuz — contradicting Iran's own deputy foreign minister. Norway's Maritime Authority banned all Norwegian-flagged ships from the Strait. Israel began a new wave of strikes in Beirut, hitting a building less than 1km from Lebanon's government headquarters.

The USS Gerald Ford reported a non-combat fire, extinguished with no injuries.
Evening — CENTCOM reveals scale, Larijani's message: CENTCOM disclosed approximately 6,000 targets struck in Iran, 60+ ships damaged or destroyed, 30+ minelayers eliminated — the first comprehensive official tally of the campaign's scope. Iran's security chief Larijani told Trump "quick victory is impossible" and that Iran would "not relent." Treasury Secretary Bessent confirmed he will meet Chinese VP He Lifeng in France on March 15–16. The IDF disclosed it had struck Basij positions in Tehran. The USO ETF neared a 7-year high as oil approached $100 per barrel. Iran's foreign minister added a contradictory note: ships can pass Hormuz if they coordinate with the Iranian Navy.
Evening — Netanyahu speaks, Russia implicated, markets close above $100: Netanyahu held his first press conference of the war Thursday evening, declaring Israel is creating conditions for regime change in Iran, confirming strikes on Iranian nuclear scientists, and threatening Khamenei and Hezbollah's Qassem by name. Simultaneously, Western officials revealed suspicions that Putin is providing satellite imagery and drone targeting to Iran.
