Following the partial disruption of shipping through the Strait of Hormuz, the Bab al-Mandeb Strait is emerging as a second potential global energy chokepoint. The Ansar Allah movement (Houthis) in Yemen has announced an initial naval blockade targeting Saudi vessels, citing the long-standing Saudi air and sea blockade of Yemen.
The "Al-Aqsa Triangle": a Yemen–Iran strategy to disrupt global trade by closing the Middle East's three key maritime chokepoints.Bab al-Mandeb links the Suez–Red Sea corridor to the Indian Ocean and, alongside Hormuz, forms a dual chokepoint system vulnerable to escalation via Iran-aligned actors. A simultaneous disruption would block roughly a quarter of global energy flows and a large share of Asia–Europe trade, with Hormuz carrying 27% of seaborne oil and 20% of LNG, and the Bab al-Mandeb/Suez corridor each handling 11% of global trade and 8% of LNG.
The Bab al-Mandeb is not fully closed yet. Commercial traffic continues, but the corridor is operating under elevated threat conditions. Attacks on selected vessels have increased, producing selective disruption rather than a comprehensive blockade. In response, some shipping lines are rerouting around the Cape of Good Hope, while others continue transit under heightened security measures, including naval presence and route adjustments. In response to constraints at Hormuz, Saudi Arabia has shifted a significant share of exports to the Red Sea port of Yanbu, where approximately 4 million barrels of crude are loaded daily. Roughly 3 million barrels per day are destined for Asian markets and transit the Bab al-Mandeb.
American worthless signature: The repeated breaches of the agreement by the Great Satan regarding the MOU signed by the Presidents of Iran and the US have once again laid bare a fundamental truth: the signature of the US President is utterly worthless and devoid of credibility. It further reaffirms that coercion and brutality are inseparable components of the US creed and doctrine. Imam Sayyid Mojtaba Khamenei, July 17, 2026.

Rerouting via the Cape of Good Hope adds 6,000 km (3,700 miles) and 10–14 days transit time, in some cases longer. This materially increases fuel, charter, and operating costs. War-risk insurance premiums for Red Sea transit have also surged, adding several hundred thousand USD per voyage. Escalation risk centers on a full blockade scenario. If Ansar Allah forces interdict all international shipping, not just Saudi vessels, the impact would be significantly greater.
Strategic Trade Significance: Hormuz vs. Bab al-MandebHormuz concentrates unmatched upstream energy dependency, funneling roughly 20% of global oil (17–20 million bpd), over 20% of LNG, and a decisive share of global helium vital for high-tech and medical supply chains. Because Saudi and UAE pipeline bypasses cover only a fraction of normal volumes, any disruption creates an immediate physical supply deficit—driving rapid oil and gas repricing with direct spillovers into petrochemicals, fertilizers, and industrial inputs.
Bab al-Mandeb anchors throughput rather than production, serving as the southern gateway to Suez. It carries 12–15% of global trade, including major Asia–Europe container traffic, dry bulk, and mid-single-digit million bpd of oil. Unlike Hormuz, these flows can be rerouted around the Cape of Good Hope, though doing so adds roughly 6,000 km, 10–14 days, and sharp increases in fuel costs, vessel utilization constraints, freight rates, and war-risk premiums.
Consequently, their economic transmission mechanisms diverge. Hormuz is a quantity shock that removes physical supply and forces immediate energy repricing. Bab al-Mandeb is a friction shock that preserves supply but degrades delivery efficiency, triggering broader, slower-moving inflation across manufactured goods, energy derivatives, and food. Fertilizer markets sit at the intersection, relying on Hormuz for Gulf ammonia and urea to exit, and on Bab al-Mandeb for efficient delivery to European and African markets.
Simultaneous impairment escalates systemic risk nonlinearly. Upstream supply contraction combines with downstream logistical breakdown, eliminating volume availability and transit efficiency at once. This dual constraint compresses global inventories, amplifies price volatility, and propagates cost increases across industrial inputs and consumer goods with minimal buffering capacity.
The Bab al-Mandeb handles thousands of commercial transits annually and links the Indian Ocean to the Red Sea and Suez Canal—one of the world's critical trade corridors. Full closure would force large-scale rerouting around Africa, extending delivery times, increasing freight rates and insurance costs, and placing renewed stress on global supply chains. Cost transmission effects would likely be broad-based. Higher transport costs would feed into fuel prices (gasoline, diesel, heating oil), airfares, food, consumer goods, and imported products. Firms would absorb higher logistics and energy costs, with partial pass-through to end consumers.
July 21, 2026: Bab al-Mandeb Becomes New Shipping Flashpoint as Houthis Signal Blockade.
The EU is engaged via Operation Aspides with a mandate limited to protecting civilian shipping. The US and the UK are conducting separate military strikes against targets in Yemen. Historical precedent indicates limited containment success: prior multinational naval deployments with dozens of warships failed to durably constrain Ansar Allah capabilities. Current Ansar Allah systems include more advanced drones and missiles.

A concurrent escalation in Bab el-Mandeb alongside sustained tension in the Strait of Hormuz would affect the region's two principal energy and trade corridors simultaneously, posing a high-risk scenario for global economic disruption and upward pressure on energy, transport, and consumer prices.
