South Africa’s sea freight is being hit hard by the Iran–USA war crisis: rising diesel costs, rerouted shipping lanes, and surging insurance premiums are driving up import and export expenses, while Cape ports are seeing increased traffic as vessels avoid the Strait of Hormuz and Suez Canal.
⚓ Global Shipping Disruptions
- Strait of Hormuz blockade: Nearly 20% of the world’s oil passes through this chokepoint. Its shutdown has forced vessels to reroute around the Cape of Good Hope, adding 10–20 days to transit times and raising freight rates by up to 50%.
- Insurance premiums: Ships transiting conflict zones face sharply higher premiums, costs that ripple into global supply chains.
- Commodity disruptions: Beyond oil, supplies of fertilizer, sulfur, and helium are affected, impacting agriculture and manufacturing worldwide
