Bab el-Mandeb Strait effectively closed by 2026?

Platform comparison

Market context

The Bab el-Mandeb Strait, a critical chokepoint linking the Red Sea to the Gulf of Aden, faces a potential effective closure if transit calls drop to ten ships or fewer over a seven-day average. This threshold represents a near-total halt in maritime flow through a lane that normally handles 14% of global trade, with recent data showing a 7-day moving average of 33 ships as of March 2026[9]. While the current crowd-implied probability sits at 0%, historical precedents suggest such closures are plausible during geopolitical escalations; notably, Yemeni forces declared the strait closed to Israeli shipping on 5 May 2026, and Houthi officials warned in April 2026 that the passage could be shut entirely if Sanaa decides[2].

Traders should monitor announcements from Houthi leadership regarding the US naval blockade of Iran, as these have previously triggered transit restrictions[2]. The primary catalyst is the publication of IMF PortWatch data, which will resolve the market immediately if the 7-day average falls below the threshold. Recent trends indicate Bab el-Mandeb transits are declining, though a slight uptick was noted for the Suez Canal in the week ending 10 March[1]. Any escalation in tensions between the US and Iran, or further Houthi declarations targeting non-Israeli vessels, could rapidly depress ship counts below the settlement trigger.
