Hormuz: The Strait Closes and No One Gives the Order

I wrote a book about how the Strait of Hormuz closes. Not by blockade — by insurance. Then it happened that way.Twenty percent of the world's petroleum moves through a stretch of water twenty-one nautical miles wide. Almost everything written about that corridor treats it as a military problem: warships, missiles, whether a fleet can keep the lane open. This episode argues that was always the wrong lens — and walks through the mechanism that actually shuts a sea lane, which requires no order, no declaration, and no shot fired.In this episode:Why a strait closes on a spreadsheet in London rather than on the waterWhat I got right about the sequence — and what I specifically did not predictThe dossier: the geography that forces tankers into predictable lanes, the three asymmetric capabilities that make the corridor contestable, and the fourteen-to-twenty-one-day refinery countdown that begins the moment transit haltsThe call: where I expect this method to appear next, and the one signal worth watching — the gap between when the underwriters move and when the governments speakNot predictions.
