Major lines shifted routes around the Cape since late 2023 for Red Sea risks, with further shifts in 2026 to avoid Strait of Hormuz. They avoid hazards in the Bab-el-Mandeb Strait and Strait of Hormuz. Houthi attacks from 2023 to 2025 sparked the change. The Iran war extended disruptions. Yet South Africa gains little. Most vessels transit without stopping. While many vessels transit without stopping, ports like Durban and Cape Town have seen surges in some activities, including 21% rise in container arrivals and 112% bunkering revenue increase in Cape Town.
Data confirms the mismatch. Cape shipping rerouting boosts passage numbers. However, ships rarely dock. They skip berthing fees, cargo handling, bunkering, repairs and maintenance. South Africa’s main ports capture minimal revenue. Reports and analyses, such as from Transnet and industry experts, have exposed this gap. Participants noted differentiated effects across commercial domains. Short-term gains prove elusive.
Moreover, rivals advance. Namibia’s Walvis Bay expands bunkering capacity. Mauritius’s Port Louis does the same. These hubs position for windfall traffic. South Africa lags. It misses services revenue from the surge.
Increased traffic heightens risks. Cape shipping rerouting widens space for illicit activities. Surveillance burdens grow. Non-state actors face criminal exposure at sea. Information-sharing on maritime crime falters. Diplomats highlight intelligence channeling issues.
Uninsured vessels add dangers. They transit hazardous waters. Accidents shift costs to the coastal state. Lives lost. Pollution threats loom over sensitive coastlines.
South Africa faces challenges in maritime security coordination and strategy implementation amid increased traffic. This hampers balance between quick wins and long-term reform. Policy coordination stalls.
Investors eye infrastructure plays. Watch Walvis Bay and Port Louis expansions for yield. South Africa must craft a strategy soon. Rival hubs gain ground. Policymakers should prioritise surveillance tech and insurance protocols. Development finance can bridge gaps. Opportunities lie in secure bunkering and regional pacts.
