The Strait of Hormuz: The World's Most Dangerous Chokepoint

230 oil tankers anchored in the Persian Gulf with nowhere to go. Oil at $126/bbl. Gas above $4/gal. South Korea's worst trading day in 43 years. The largest disruption to world energy supply since the 1970s — through a 6-mile navigable corridor.Geography is the whole story. Two 2-mile lanes plus a 2-mile separation zone. 135 ships per day. 20 million barrels of oil — 20% of global petroleum consumption. 20% of LNG. 30% of internationally-traded fertilizers. 45% of global sulfur. 84% of that oil goes to Asia.History explains 2026. Tanker War (1981-88) — 546 vessels damaged, 400+ sailors killed. USS Vincennes shot down Iran Air 655 — 290 dead including 66 children, $131.8M paid but no formal apology, seared into Iranian national memory. 2019: Stena Impero seizure, Saudi Aramco Abqaiq attack — 5.7M bpd offline overnight, the largest single oil disruption in modern history.The 2026 escalation. JCPOA expired October 18, 2025. Iran's nuclear breakout time down from 12+ months to weeks. US + Israel launched Operation Epic Fury Feb 28. Qatar force majeure on LNG March 4. Oil past $100 March 8. Iran laying mines in shipping lanes March 10 — ~6,000 naval mines on hand and they don't need many.Insurance asymmetry. Pre-crisis war-risk: $40K per Gulf transit. After the crisis: 1% of hull value — $1.2M for a $120M tanker. For US/UK/Israel-linked ships: 5% — $6M. You don't need to sink a tanker. You need to make it uninsurable.Then Iran pivoted from binary closure to toll booth. Yuan-denominated transit fees, ~$1M per ship. China gets 40% of its oil through Hormuz and is paying tolls in yuan. China + Russia vetoed the UN Security Council reopening proposal.Bypass math: Saudi Petroline 7M bpd, UAE Fujairah 1.5M. Total ~9M against Hormuz's 20M. 11M-bpd gap. Zero LNG bypass. If Bab el-Mandeb closes too — no maritime route out of the Persian Gulf.Ripple: European gas doubled. US gas $4/gal (California $5+). Fertilizer +40% in 3 weeks. Kuwait/Qatar 99% desalination — drinking water for 70% of the population at risk.RELATED EPISODESThe 38-Day Iran War — the kinetic chapter the 2026 closure grew out ofThe Iran Blockade — the Hormuz arc sequel that picks up where this episode endsThe AI Chip War — the parallel chokepoint story: silicon as Hormuz of computeCHAPTERS00:00 Cold open — 230 tankers anchored, the strait is closed again00:47 Geography — the 6-mile corridor and the Traffic Separation Scheme01:39 What flows through — 20M bpd, 20% LNG, 30% fertilizers, 45% sulfur02:20 Country dependencies — Japan, South Korea, China03:24 The Tanker War (1981-88) and Operation Praying Mantis04:00 USS Vincennes and Iran Air 655 — what Iran remembers05:08 2019 — Stena Impero seizure, Abqaiq attack, 5.7M bpd offline05:49 Nuclear context — JCPOA expiration and breakout time06:28 Iran's two navies — regular Navy and IRGC swarm doctrine07:32 The 2026 escalation — Epic Fury, Qatar force majeure, oil at $10008:36 The insurance pivot — one mine and tankers become uninsurable09:54 Iran's toll-booth pivot — yuan-denominated transit fees10:27 Why China benefits, and the UN Security Council veto11:11 The bypass math — 9M bpd pipelines vs 20M bpd through the strait12:38 Dual chokepoint scenario — if Bab el-Mandeb closes too13:50 Ripple effects — European gas, US fuel, fertilizer, helium, drinking water15:50 Outlook — weeks-to-months reopening, $135 Brent, Qatar LNG expansionSOURCESIEA / EIA — Hormuz throughput statistics + petroleum reservesLloyd's of London + Joint War Committee — war-risk premium dataIISS — Iran naval doctrine, IRGC fast-attack capabilitySaudi Aramco — Petroline + Abqaiq attack disclosuresICE Futures — Brent/WTI/Dubai crude price seriesKRX — South Korea KOSPI trading dataUN Security Council — Mar 2026 reopening-proposal veto recordIAEA — Iran enrichment + breakout-time reporting
