Every major supply chain of the 21st century runs through 65 kilometres of water. Not a metaphor. A measurement. The Strait of Hormuz is 39 kilometres wide. The Bab el-Mandeb is 26 kilometres wide. Both are now contested by the same axis. Iran holds Hormuz. The Houthis threaten Bab el-Mandeb. Together they declared solidarity on March 26 with “fingers on the trigger.” Here is what flows through those 65 kilometres. Oil. Twenty to twenty-five percent of global seaborne petroleum through Hormuz. Another 12 percent through Bab el-Mandeb. Combined: one-third of the world’s oil. Natural gas. Twenty percent of global LNG through Hormuz. QatarEnergy declared force majeure on March 24. Trains 4 and 6 are offline. 12.8 million tonnes per annum will not return for three to five years per QatarEnergy’s CEO. Helium. Qatar produced one-third of the world’s helium as a byproduct of that same LNG. Spot prices have doubled. Samsung and SK Hynix have six months of inventory. After that, semiconductor fabrication slows. Every advanced chip on earth requires helium somewhere in its manufacturing process. There is no substitute. Semiconductors depend on helium. AI training depends on semiconductors. Quantum computing depends on helium directly, cooled to millikelvin temperatures in dilution refrigerators. Post-quantum cryptography depends on the quantum computers that depend on the helium that came from the LNG plant that was hit by missiles fired from the country that controls the strait. That is not a supply chain. That is a dependency chain five layers deep terminating at a single geographic coordinate. Fertilizer. Qatar and Iran supply 20 percent of global urea exports. Urea hit $690 per tonne. American farmers are shifting from corn to soybeans because nitrogen fertilizer derived from natural gas is now unaffordable. Internet. Ninety-five percent of global data traffic travels through undersea cables buried one to two metres beneath the seabed in those same two straits per TeleGeography. FALCON. GBI. EIG. SEA-ME-WE 6. AAE-1. FLAG. The IRGC threatened to cut them on March 28. The financial data connecting every stock exchange on earth runs through the same water as the oil tankers. Money. Iran collected yuan tolls from vessels transiting Hormuz under IRGC escort per Lloyd’s List. The first non-dollar energy settlement imposed by force at a global chokepoint in the post-Bretton Woods era. Not replacing the dollar. Bifurcating it. Rockets. SpaceX uses 10,000 to 20,000 litres of helium per Falcon 9 launch. The Starship that carries the Starlink satellites that replace the undersea cables threatened by the same axis uses autogenous pressurization because Musk saw this dependency before the war proved it. SpaceX is filing the largest IPO in history this week at $1.5 to $1.75 trillion. Filing into a war that validates every thesis that built his company. Nuclear. Israel struck Ardakan, Iran’s only yellowcake plant, and Arak, its heavy water complex, on March 27. JSOC is planning contingency operations to seize 450 to 970 pounds of enriched uranium from underground tunnels per CBS and Axios. Three carrier strike groups, two Marine Expeditionary Units, and DEVGRU operators are staged for April 6. Oil. Gas. Helium. Chips. AI. Quantum. Fertilizer. Food. Cables. Settlement. Rockets. Satellites. Nuclear weapons. The largest IPO in history. The birth of a parallel monetary system. All of it through 65 kilometres of contested water. The market has priced an oil disruption. It has not priced a civilizational chokepoint. Full analysis: open.substack.com/pub/shanak…
