The Most Important 21 Miles on Earth
Between Iran and Oman lies a 21-mile-wide strait through which 20% of the world's oil supply passes every day. That's roughly 21 million barrels daily. If the Strait of Hormuz closes — even temporarily — the global economy goes into cardiac arrest. This isn't hypothetical. Iran has explicitly threatened closure as a response to military strikes. Understanding this chokepoint is essential for anyone with money in the markets.
The Scenario
Iran deploys naval mines, fast attack boats, and anti-ship cruise missiles to deny passage through the strait. Commercial shipping halts. Insurance rates for tankers skyrocket, effectively closing the strait even without a physical blockade. Within 48 hours: oil jumps to $150+. Within a week: $200+ oil is possible. Global recession becomes near-certain.
Why It Probably Won't Happen
Iran also exports through Hormuz. Closing it would destroy their own oil revenue. China — Iran's biggest oil customer — would be furious. And the US Navy's 5th Fleet is specifically positioned to keep the strait open. The threat of closure is more valuable to Iran than actually closing it. But "probably won't happen" is not "can't happen."
How to Hedge
Oil calls: OTM calls on USO or XLE are cheap insurance against a spike. Defense stocks: Naval-focused contractors (Huntington Ingalls, General Dynamics) benefit from any Hormuz tension. Cash reserves: Having dry powder during a crisis lets you buy the panic. Commodities broadly: Gold, oil, natural gas all spike in supply disruption scenarios.
Key level: If oil (WTI) breaks above $110, the Hormuz premium is getting priced in. Above $130, the market is pricing in actual disruption. Position accordingly.
