Between War and the Global Economy

Coordinated American and Israeli strikes hit Iran's nuclear enrichment facilities at Natanz and Fordow, its ballistic missile launchers, the headquarters of the Islamic Revolutionary Guard Corps, and dozens of air defence and command nodes. Trump declares Iran a "core national security threat" and invokes Article 51 self-defence at the United Nations Security Council. Iran's response arrives within hours: a simultaneous barrage of ballistic missiles and drones targeting US military installations across seven countries. It is the largest Iranian retaliatory strike in history, dwarfing the 330-missile volley of April 2024. Britain's Prime Minister Starmer authorises the use of Diego Garcia and RAF Fairford for "specific and limited defensive purposes," a carefully worded commitment that stops well short of joining the offensive. And in Tehran, in what will prove to be his final act, Supreme Leader Khamenei orders the Strait of Hormuz closed.

Ayatollah Ali Khamenei, 86 years old and Iran's Supreme Leader since 1989, is killed in a strike on his Tehran office. He had held power for 37 years, longer than the Shah he helped overthrow. A three-member transitional council assumes emergency authority. In Tehran, 100,000 people flee the city in the first 48 hours. Trump, briefly, sees opportunity: talks would now be "much easier," he says. The window closes almost immediately.

Hezbollah, the Iranian-backed Lebanese militia with an estimated 150,000 rockets and four decades as Tehran's most capable proxy, launches a revenge barrage at northern Israel. Israel responds with a ground offensive into southern Lebanon, opening a second active front in a war that is 72 hours old. 112,000 Lebanese are displaced on the first day. The Lebanese government bans Hezbollah's military activities and demands it surrender its weapons. Hezbollah calls the order "misplaced" and keeps firing. Britain, France, and Germany condemn Iran's counter-strikes and call for diplomacy, but none commit forces. The war has doubled in scope before its first week.

The International Atomic Energy Agency confirms that Natanz, the centrepiece of Iran's enrichment programme, has sustained damage. Fordow, built into a mountain, is "substantially damaged but not destroyed." The stated military objective is being achieved. But the US Navy's promise to escort tankers through the Strait "as soon as possible" carries a qualifier that tells its own story. Traffic is collapsing. In the open ocean south of Sri Lanka, the US Navy torpedoes the Iranian warship Iris Dena, killing 84 sailors. It is the most significant naval engagement in decades.

The collapse is captured in a single data point from the IMF's PortWatch maritime tracking system: where a week earlier, 95 vessels and 53 tankers transited the Strait, today the number is three. None carry oil. Over a thousand ships sit idle on both sides as Iran's Revolutionary Guard lays mines in the channel. The world's most important energy corridor, through which 20 million barrels of oil and a quarter of global LNG pass each day, has shut down. The coalition controls the skies over Iran. Iran controls the water beneath them.

Qatar's Energy Minister delivers a message that reverberates through every trading floor in the world: no production restart until complete cessation of hostilities. Qatar supplies roughly 20% of global liquefied natural gas, the fuel that heats homes in Japan, powers factories in South Korea, generates electricity across Southeast Asia. Iraq, Kuwait, and the United Arab Emirates also curtail or stop output. Not out of solidarity with Iran, but because they physically cannot load tankers when the Strait is closed and storage tanks are full. The consequences spread at the speed of a futures contract. South Korea announces fuel price caps for the first time in 30 years. Bangladesh shuts its universities to conserve power. China orders its refiners to halt fuel exports. A war between three countries is now a war on the global economy.

It is a demand no Iranian leader can accept, not even a weakened transitional council operating under bombardment. The same day, Spain permanently withdraws its ambassador to Israel, the first major European government to formally break with the coalition. Behind the scenes, the economics of the war are being quietly renegotiated: Washington announces a sanctions waiver allowing India to purchase stranded Russian oil. Moscow reports a "significant increase" in energy demand from its allies. Strange bedfellows. Strange beneficiaries.

Iran's Assembly of Experts, the 88-member clerical body that selects the Supreme Leader, names Mojtaba Khamenei as successor. He is the dead leader's 56-year-old son, a hardliner aligned with the Revolutionary Guard and sanctioned by the United States since 2019. The appointment signals continuity, not reform. The regime is closing ranks under bombardment, not falling apart. Israel's Foreign Minister Katz responds within hours. Britain readies the aircraft carrier HMS Prince of Wales but does not commit it. The regime change that Washington and Tel Aviv had hoped the strikes would catalyse has not materialised.

Brent crude futures touch their 52-week high in early trading, then collapse. A $35 swing in a single session. The volatility alone is devastating: fuel price spikes, fertiliser cost surges, inflationary pressure in every economy on earth. The International Energy Agency calls the disruption "temporary logistical," a characterisation that convinces nobody. The seventh American soldier to die in the conflict, a sergeant at Prince Sultan Air Base in Saudi Arabia, succumbs to injuries from an earlier missile strike. Iran's Hormuz blockade is doing what 500 missiles could not: imposing a cost that no amount of air superiority can bomb away.

Israeli jets hit Tehran's fuel storage facilities without coordinating with the United States. Massive fires. Toxic smoke across the capital. Residents report black, oily rain. Washington is "formally angry." This is exactly the kind of escalation the Americans had tried to avoid. The US Energy Secretary publicly declares that the United States will not strike Iran's energy infrastructure, drawing a red line that Israel has already crossed. The Revolutionary Guard Corps, sensing the divide, issues a statement that functions as both a rebuke and a demand. In Congress, Democrats file war powers resolutions. Russia-linked hackers begin appearing on a new front: cyber operations supporting Iran, using drone tactics Moscow learned in Ukraine.

B-1 and B-52 strategic bombers arrive in the theatre. These are aircraft designed for sustained bombardment, not surgical strikes. The US Navy destroys 16 Iranian mine-laying vessels in the Strait. Netanyahu openly discusses creating "conditions for regime change" in Tehran. But the eighth American soldier is killed, over 140 are wounded, and G7 finance ministers begin discussing an emergency release of strategic oil reserves, an implicit acknowledgement that the economic damage is no longer containable. Turkey, a NATO ally, intercepts a third Iranian missile in its own airspace.

Israeli commandos kill Iranian officials in a luxury hotel in central Beirut. The war is expanding beyond southern Lebanon into the capital itself. Russia-linked hackers appear on a new cyber front, supporting Iran with what Britain's Defence Secretary later calls Putin's "hidden hand." Kurdish opposition groups, reportedly backed by Mossad and the CIA, claim covert operations deep inside Iranian territory. China deploys a signals intelligence vessel to the Gulf of Oman, placing a major surveillance platform within observation range of the conflict. Mojtaba Khamenei has not spoken publicly since his appointment five days ago. Pentagon spokesman Hegseth claims he was "wounded, likely disfigured."

The International Energy Agency uses a phrase it has never used before: "largest oil supply disruption in history." Ten million barrels per day offline. The combined output of Saudi Arabia, Iraq, and Iran, gone. The United Nations Security Council passes a binding resolution 13 votes to zero, with two abstentions, demanding Iran halt its attacks. Russia and China abstain rather than vetoing. It is a crucial signal: Tehran's two most important diplomatic protectors are unwilling to shield it from formal condemnation. Mojtaba Khamenei finally breaks his five-day silence.

Pentagon spokesman Hegseth announces that Iran's defence industrial base has been "functionally defeated." It can no longer manufacture new ballistic missiles or replace the weapons it has already fired. Israeli intelligence identifies and kills top nuclear scientists. Over 3,000 targets have been struck across Iran. By any conventional metric, the campaign has achieved its objectives. But six more Americans die when a KC-135 refuelling tanker crashes in western Iraq, bringing the total to 13. An Iran-backed militia immediately claims responsibility; the Pentagon attributes it to operational failure. The IEA announces a 400 million barrel strategic reserve release, the largest in its history. France and Italy open direct talks with Iran on safe passage through Hormuz, the first European diplomatic channel separate from the American military operation. The New York Times publishes a poll: this is the least popular American foreign war in modern polling history. In Michigan, a synagogue is attacked by a man whose family was killed in Israeli strikes on Lebanon.

In a single decision that reverses two weeks of deliberate restraint, the United States strikes more than 90 military targets on Kharg Island, the terminal through which 90% of Iran's oil exports flow. Trump shares video of the strike. Until today, Washington had explicitly refused to target Iran's energy infrastructure, even as Israel hit Tehran's fuel depots without permission. Now both allies are striking oil. Iran claims its exports continue; the claim is contested. Separately, two Indian-flagged tankers successfully transit the Strait of Hormuz, the first commercial passage since the blockade began. Iran allowed them through. Friendly nations can pass. Western-flagged ships cannot. In Lebanon, Israel signals a "massive" ground invasion described by officials as "like Gaza." Hamas publicly urges Tehran to halt its attacks on Gulf states, an extraordinary rift within the Iranian alliance. And inside the White House, the administration's own artificial intelligence adviser publicly says what no senior official has said before.
