What this briefing covers
This briefing examines the emerging geopolitical risks surrounding the Bab al-Mandeb strait, a critical maritime chokepoint for global petroleum transit, and evaluates the potential implications for energy market stability.
The data / what’s happening
The 2026 Iran war has turned the Bab el-Mandeb strait into a critical pressure point for global oil. After U.S. and Israeli strikes on Iran beginning February 28, 2026 effectively closed the Strait of Hormuz, Gulf producers — led by Saudi Arabia — began rerouting crude westward to Red Sea terminals, pushing flows through Bab el-Mandeb sharply higher even as Iran and its allies threaten this second chokepoint (CNBC, June 5, 2026). The waterway connects the Indian Ocean to the Mediterranean via the Red Sea and Suez Canal.
What’s notable or overlooked
Oil and product flows through Bab el-Mandeb nearly doubled to roughly 7.2 million barrels per day in April 2026, up from about 3.9 million b/d in February before the strikes — and well above the strait’s 2024 baseline of about 4.1 million b/d (CNBC, June 5, 2026; TIME, April 8, 2026). The surge reflects the strait’s new role as a relief valve for oil diverted away from the closed Strait of Hormuz. That is precisely what makes it a vulnerability: a disruption here would force lengthy rerouting around the Cape of Good Hope, adding transit time and freight cost at the moment the market has the least slack.
The Tension
The vulnerability is structural: the more oil Bab el-Mandeb absorbs as a Hormuz workaround, the more damaging a closure would be. Iran’s Revolutionary Guard has threatened to close the strait, and in early June 2026 Houthi forces aligned with Iran escalated threats against Red Sea shipping (Euronews, June 8, 2026; Al Jazeera, April 6, 2026). With roughly 7.2 million b/d now transiting — much of it the diverted Gulf crude keeping global supply from tightening further — a sustained disruption would pull a large volume of liquid fuels out of efficient distribution at the worst possible moment (CNBC, June 5, 2026). Unlike Hormuz, Bab el-Mandeb has a physical alternative in the Cape of Good Hope route — but at materially higher cost and weeks of added transit (TIME, April 8, 2026).
Risks / counterpoints
The primary risk is a kinetic event that forces commercial vessels to cease transit, leading to immediate supply constraints and elevated global crude prices. Conversely, a counterpoint is that international naval coalitions have previously maintained a presence in the region to deter such actions, potentially mitigating the likelihood of a complete closure. Furthermore, alternative routing, while costly, remains a viable fallback for global trade.
