In April 2026, more cargo ships rounded the Cape of Good Hope — the rocky southern tip of South Africa — than at any point in modern record-keeping. According to Veson Nautical, a shipping data firm, tanker traffic on the Cape route reached a record 24 million deadweight tonnes during the week of April 13. On its face, this is a strange milestone. The Cape route is the long way: ships travelling between Asia and Europe could shave at least two weeks off their voyages by going through Egypt's Suez Canal instead. So why are they choosing the detour?
The answer begins in late 2023, when Yemeni Houthi militants started attacking commercial vessels in the Red Sea. The Houthis, an armed group aligned with Iran, said the strikes were retaliation for Israel's military campaign in Gaza. Shipowners responded by abandoning the Red Sea and routing around Africa instead. That alone wasn't surprising — companies routinely avoid war zones. What's surprising is what happened next.
A ceasefire eventually halted the immediate fighting in Gaza. The United States and Israel launched military strikes against Iran beginning February 28, 2026, targeting the Houthis' main sponsor. By traditional logic, that combination — ceasefire plus decisive military action — should have brought ships streaming back to Suez. It didn't. Tanker traffic to the Red Sea did make a 'tentative' return in late 2025, but the Houthis have not taken any significant action during the latest conflict. Even so, container giant Hapag-Lloyd told customers it had attempted 'first cautious attempts' to return to Suez but 'had to stop'. Bulk-grain carriers also peaked on the Cape route in mid-March, only marginally below a previous high in July 2024.
Here's the catch: shipping is a business, and businesses serve customers. Hapag-Lloyd's chief executive Rolf Habben Jansen explained that clients now value supply-chain stability over saving money or time. The longer Cape route is more expensive — freight rates climbed from about $2,500 per 40-foot container to roughly $3,000 in mid-March before settling around $2,700 — but those costs are predictable. A missile attack is not. Customers, in effect, are paying a premium for boredom.
The ripple effects are visible across southern Africa. Average container arrivals at South Africa's five main ports — Maputo, Durban, Port Elizabeth (Gqeberha), Cape Town and Walvis Bay — are up 21% since the first strikes against Iran. The week of April 6 saw the highest arrivals yet, 71% above pre-conflict weekly averages. The reason isn't a sudden boom in African manufacturing; it's logistics. Longer voyages mean more refuelling stops and more demand for port services. According to supply-chain intelligence firm Project44, this resulted in 'much higher traffic and an increase in refuelling at southern African ports.'
The broader lesson is about how supply chains remember. A waterway as critical as Suez — through which roughly 12% of global trade once flowed — cannot simply switch back on the day a ceasefire is signed. Shipping contracts, insurance policies, and routing decisions all carry inertia. As Habben Jansen put it, the longer voyage 'resulted in higher costs', but customers preferred stability anyway. For now, Africa's coastline is the global economy's safer bet.
When Yemeni rebels started firing missiles at cargo ships in 2023, they didn't just disrupt one waterway — they redrew the map of global trade, possibly for years.
Sea traffic around the Cape of Good Hope — the southern tip of Africa — hit a record high in mid-April 2026. Tanker volume measured by ship capacity reached an all-time peak in the week of April 13, according to data firm Veson Nautical.
The reason: shipping companies are still avoiding the Red Sea and the Suez Canal, the much shorter route between Europe and Asia. They started detouring in late 2023 after Houthi militants in Yemen began attacking vessels, claiming retaliation for Israel's war in Gaza. Even after a ceasefire and a US-Israeli military campaign against Iran (which backs the Houthis), most shippers are staying on the longer route.
Imagine a highway shortcut that saves you two weeks of driving — but there's a small chance someone shoots at your car. Even if the shooting stops, you might keep taking the long way for a while, just to be sure.
Almost everything you own — your phone, sneakers, even some of your food — moved across an ocean on a container ship. When ships take a longer route, costs ripple through to retail prices, delivery times, and ultimately inflation. For students thinking about careers in logistics, international business, energy, or geopolitics, this is a live case study in how a regional conflict can rewire global commerce in real time.
The Suez Canal opened in 1869 specifically to avoid the Cape route — it was one of the great engineering shortcuts of the modern era. If shippers stay away for years, expect long-term winners (South African ports, alternative logistics hubs) and losers (Egypt, which collects billions in canal tolls). Watch whether insurance underwriters at Lloyd's of London lower Red Sea risk premiums — that's the real signal that traffic will return, not any politician's announcement.
