Cape of Good Hope diversion adds 6,000 nautical miles and three or four weeks to delivery times and has driven up oil prices

More than 100 container ships have been rerouted around southern Africa to avoid the Suez canal, in a sign of the disruption to global trade caused by Houthi rebels attacking vessels on the western coast of Yemen.

The shipping company Kuehne and Nagel said it had identified 103 ships that had already changed course, with more expected to go around South Africa’s Cape of Good Hope.

The diversion adds about 6,000 nautical miles to a typical journey from Asia to Europe, potentially adding three or four weeks to product delivery times.
