The Red Sea-Suez corridor handles roughly 12 % of global trade and over 30 % of containerized trade between Asia and Europe. From late 2023, Houthi missile and drone attacks on commercial shipping in the Bab-el-Mandeb strait at the southern entrance of the Red Sea forced a near-total reroute of major container lines around the Cape of Good Hope. The disruption is the most significant maritime trade reroute since the Suez closure of 1967-1975.

The numbers

  • Suez Canal transit revenue dropped from ~$10 B/year pre-crisis to under $4 B in the worst months of 2024.
  • Asia-Europe transit times via the Cape of Good Hope: 33-40 days vs. 22-28 days via Suez. About 10-14 extra days per voyage.
  • Container freight rates spiked 200-300 % in early 2024 before settling at ~50-80 % above pre-crisis levels.
  • Approximately 80 % of container traffic that previously transited Bab-el-Mandeb has rerouted around Africa.

The risk math

Insurance pricing tells the story. War-risk premiums for Red Sea transits went from ~0.05 % of hull value to 0.7-1.0 % within weeks. For a $150 M containership and a 7-day transit, that's ~$1 M in insurance alone, before fuel, before crew hardship pay. Cape rerouting adds ~$400-500K in fuel and time costs but eliminates the war-risk premium. The math has consistently favored the Cape.

The complication is fleet capacity. Longer routes effectively absorb shipping capacity (vessels in transit longer = fewer voyages per year). This was the dominant 2024 driver of the freight-rate spike: not lost ships, but lost voyage-cycles.

Coalition responses

  • Operation Prosperity Guardian — multinational naval force with US Navy lead, primarily focused on shootdown of incoming missiles and drones. Effective at protecting transiting ships but cannot eliminate the threat at source.
  • EU's Aspides operation — separate European-led task force with stricter rules of engagement, focused on escort.
  • Strikes on Yemen — US/UK strikes on Houthi launch sites have degraded capability but not eliminated it. The Houthis adapted to mobile launchers and continue intermittent attacks.

Structural shifts in the wake

Three durable changes:

  • Carrier consolidation strategy. Major lines invested in larger ships (24,000+ TEU) to amortize fixed crew/insurance costs across more cargo. Cape routes favor mega-carriers more than Suez routes did.
  • Inventory holding rebuilt. Just-in-time inventory practices common in 2010s European retail and industrial sectors moved meaningfully toward just-in-case during 2024. Some of this reverses; some doesn't.
  • Egypt's fiscal hit. Suez revenue is ~30 % of Egyptian foreign currency earnings during normal years. The disruption forced IMF program renegotiation and Gulf bilateral support that reshaped Egyptian foreign policy alignment in unpredictable ways.

Even after a Yemen ceasefire scenario, the insurance-market memory of this period persists. War-risk pricing for the corridor is unlikely to return to pre-2023 baselines within the near term, which keeps marginal Asia-Europe shipping decisions weighted toward Cape routing for years.
