How the Current Crisis Compares
The 2026 Hormuz crisis is fundamentally different from any previous oil shock. While the 1973 OPEC embargo saw a larger percentage price increase (+400%), it was a deliberate production cut that left the physical shipping infrastructure intact. Oil still flowed from non-embargoing nations, and within months, alternative supply arrangements were in place. The 1990 Gulf War disrupted 4.3M barrels/day, but the strait itself remained open for neutral shipping.
What makes 2026 unique is the physical bottleneck. The Strait of Hormuz is a geographic chokepoint — 21 nautical miles wide at its narrowest — and its closure means that even oil that has been pumped from the ground cannot reach its destination. Saudi Arabia's 7.2M bbl/day of Hormuz-bound exports can't simply be rerouted; only 5M bbl/day can reach the Red Sea via the Petroline, and the remaining 2.2M bbl/day is trapped behind the geographic barrier.
The 2021 Suez Canal blockage, while dramatic, lasted only 6 days and affected a different trade route. The 2024-25 Red Sea crisis saw 12% of global traffic rerouted around the Cape of Good Hope — the same solution being applied now, but at a vastly larger scale. The current crisis reroutes not 12% but 65% of Hormuz traffic, requiring three times as many vessels to take the detour, at a time when global shipping capacity is already strained.
Perhaps most concerning is the insurance dimension. In all previous crises, ships could still transit at some level of risk premium. In 2026, all six major P&I clubs have withdrawn entirely, meaning no commercially viable insurance exists for Hormuz transit. This is unprecedented and creates a self-reinforcing closure: even if military escorts were provided, shipowners cannot legally or financially transit without insurance coverage.
