Bab al‑Mandeb at risk
Iran has warned it may close the Bab al‑Mandeb Strait if the US and Israel escalate, threatening a vital Red Sea link that handles large volumes of global oil shipments. A closure would force ships to reroute around the Cape of Good Hope — adding transit time, higher freight and insurance costs — and analysts say Europe, especially the UK, is especially exposed to the fallout. Meanwhile the US has paused strikes on Iranian energy infrastructure until April 6 to allow diplomacy, but markets stayed volatile after Tehran rejected a US peace proposal.

The Bab al‑Mandeb handled about 4.1 million barrels per day of crude and petroleum liquids in 2024 and averaged about 4.2 million b/d in the first half of 2025, according to U.S. EIA chokepoints data.
