Red Sea transits: selectivity rules for liners as the arithmetic changes
The Loadstar · Aug 17, 2026
Since the Houthis began attacking ships in the Red Sea in October 2023, the Suez Canal has been the missing link for containerships sailing from Asia to Europe. The arithmetic was straightforward: ships could either take the Suez route and expose themselves, their crews, and cargo to Houthi attacks, or sail thousands of additional miles around the Cape of Good Hope, which, for most became the rational choice – although opportunistic ...

The corridor
Suez Canal
Global chokepointEgypt / Red SeaThe Asia–Europe short cut. When it is working, it removes roughly ten days and thousands of miles from the alternative around Africa; when it is not, that distance comes straight back and quietly eats a chunk of the world's usable container capacity.
- Diverting Asia–North Europe services around the Cape of Good Hope adds roughly 3,000–4,000 nautical miles and, in practice, ten days or more each way.
- Those extra days absorb ships without a single vessel leaving the fleet. Effective capacity falls even though nominal capacity is unchanged — the same tightening a large blank-sailing programme produces.
- Longer round trips strand empty containers at the wrong end of the trade, so equipment shortages surface in Asia weeks after the routing change.
- Rerouted services arrive in bunched waves rather than an even cadence, which converts a routing problem into a berth-congestion problem at European and Mediterranean ports.
- Cape of Good Hope — available, reliable, and roughly ten days slower each way on the Asia–Europe leg.
- Asia–Europe rail and air for a small, time-critical share of the volume, at multiples of the ocean cost.
Bab el-Mandeb Strait
Global chokepointRed Sea / Gulf of AdenThe southern gate to the Red Sea, between Yemen and Djibouti. Suez is only useful to a ship that can get through here first, which is why the two are effectively a single routing decision.
- Bab el-Mandeb and Suez are one decision, not two: a carrier avoiding this strait has already given up the canal, so disruption here shows up in Suez transit counts.
- It sits inside the Joint War Committee's listed areas, so hull war-risk premiums and crew-hazard terms are priced per transit rather than absorbed in normal operating cost.
- Vessel-tracking and canal-transit counts move within days of an incident, well before any freight index prints — this is the leading indicator for Asia–Europe cost.
- Cape of Good Hope, with the same ten-days-each-way penalty as a Suez diversion.
Cape of Good Hope
Global chokepointSouthern AfricaNot a chokepoint but the relief valve: the standing alternative to Suez, and the route that absorbs Asia–Europe traffic whenever the Red Sea is judged unsafe. Its traffic level is the cleanest single read on how much the world trusts the Red Sea this month.
- Rising Cape traffic is the mirror image of falling Suez traffic; read together they show the diversion rate directly rather than by inference.
- The route needs more bunkers per voyage, which raises fuel demand at South African and West African bunkering ports.
- Southern-ocean weather routing adds variance as well as days, so schedule reliability degrades further than the extra distance alone implies.
