News that the Strait of Hormuz has been blocked by Iran immediately sends shockwaves through global energy markets. The reason becomes clearer when you look at how global oil actually moves. Roughly one-fifth of the world’s oil supply passes through this narrow waterway, making it one of the most critical energy arteries on the planet. When a route carrying that much supply is disrupted, the world has to quickly search for alternatives, and that’s where routes like the Cape of Good Hope suddenly become very important.
When one node becomes unstable, traffic often shifts elsewhere, which explains why alternative passages outside conflict zones can suddenly see increased usage. The Cape of Good Hope offers one such detour. Unlike the Middle Eastern chokepoints currently affected by tensions linked to the Iran–US/Israel conflict and broader regional instability, this route bypasses the entire region. The trade-off, however, is distance. Tankers must travel thousands of extra kilometres around southern Africa, raising shipping costs and delivery times. But when strategic waterways face disruptions, reliability often matters more than speed.
