Red Sea & Bab el-Mandeb
The Red Sea is the hallway between the Suez Canal and the Indian Ocean, and Bab el-Mandeb — "the Gate of Tears", 18 miles wide off Yemen — is its southern door. When that door becomes dangerous, ships don't queue; they sail an extra two weeks around Africa. A tenth of world trade did exactly that from late 2023.

Are ships avoiding the Red Sea?
The honest evergreen answer: it depends on the threat level, and the fleet decides vessel by vessel. Since the Houthi attack campaign began in November 2023, Red Sea transit has been a rolling risk calculation — war-risk insurance premiums, crew safety, naval escort availability, and each carrier's own exposure. Major container lines were the first to divert and the slowest to return; bulk and tanker traffic has been more tolerant. The result is a corridor that is rarely "closed" and rarely fully normal — exactly the kind of continuous condition Farlens scores rather than reducing to a headline.
What Bab el-Mandeb is
Bab el-Mandeb is the strait connecting the Red Sea to the Gulf of Aden and the Indian Ocean, between Yemen on the Arabian side and Djibouti and Eritrea on the African side — about 18 miles (29 km) wide at its narrowest. Every ship using the Suez Canal from the south must pass it. That coupling is the point: Bab el-Mandeb risk is Suez risk, transmitted a few hundred miles north. See the Suez Canal guide for the northern half of the story.
How diversion economics work
A chokepoint disruption without closure works through insurance and time, not blockade. War-risk premiums for a Red Sea transit can multiply overnight after an attack; at some price, the two-week Cape detour becomes cheaper than the premium plus the risk. Every diverted voyage removes effective capacity from the global fleet — the same ships now cover more miles per delivery — so freight rates rise system-wide, not just on the affected lane. That mechanism is why the 2024 diversions moved container rates on routes that never touch the Red Sea at all.
Which sectors feel it — both sides
Container lines with capacity to reprice historically see rates and earnings rise during sustained diversions. Air freight absorbs urgent cargo. Fuel suppliers at Cape-route bunkering hubs see volume gains.
European importers face the longest delays. Egypt loses canal revenue — a sovereign-risk input. Marine insurers carry the war-risk book. Retailers with thin inventory buffers miss seasons, not just days.
Sector patterns describe historical tendencies, not predictions or recommendations. Any given episode can and does break the pattern.
A short history of Red Sea disruptions
- 1973 — Egypt blockaded Bab el-Mandeb during the October War; a reminder the strait has been used as leverage before.
- 2016–2018 — missile and small-boat incidents off Yemen during the civil war; premiums rose, traffic largely held.
- November 2023 onward — the Houthi campaign against commercial shipping; major carriers diverted, Suez transits roughly halved at the trough, and container rates spiked globally. The defining modern case of disruption-without-closure.
