15:33UTC

Three days of sustained attacks on Israel establish that Ansar Allah can maintain tempo. The question is whether they close the strait.

Key takeaway

The Houthi front is calibrated escalation, not symbolic gestures.

Ansar Allah struck Israel for a third consecutive day on 30 March . All projectiles were intercepted. Deputy Information Minister Mohammed Mansour described Bab al-Mandeb closure as "among our options" in a staged escalation, contingent on Israeli or US ground movement. ¹

No formal blockade has been imposed. All vessels, including US- and Israeli-linked ships, continue to transit. But three days of attacks confirm sustainable operational tempo. Combined with near-total Hormuz closure, a formal Bab al-Mandeb blockade would place simultaneous pressure on the world's two most critical oil transit routes for the first time since the 1973 oil crisis. MARAD and UKMTO have already confirmed deliberate GNSS denial spanning both chokepoints .

Deep Analysis

In plain English

The Houthis control much of northern Yemen and have been attacking ships in the Red Sea since 2024. They are also allied with Iran. For three days running, they have fired missiles and drones toward Israel; all were intercepted. Bab al-Mandeb is a narrow strait between Yemen and Djibouti. About 10% of all world trade and a large share of oil from the Gulf to Europe passes through it. If the Houthis block it, combined with Iran blocking the Strait of Hormuz, two of the world's main oil routes would be shut simultaneously. That last happened in 1973 during the Arab oil embargo. It triggered a global recession. The Houthis have not closed Bab al-Mandeb yet, but their deputy minister said it is an option.

This Event

Houthis threaten second chokepoint

A formal Bab al-Mandeb blockade combined with Hormuz closure would simultaneously shut the world's two most critical oil transit routes for the first time since 1973.

Different Perspectives

Iran human rights monitors (Amnesty International, Iran HRM, Hengaw)

Monitors documented 30 women held on capital moharebeh charges in a basement prison ward, Benyamin Naqdi's death sentence with a forced-confession broadcast, and 39 political executions since February. Iran's security courts have processed protest cases at uninterrupted wartime tempo regardless of the diplomatic track.

Lloyd's of London (war-risk underwriters)

Lloyd's held its Hormuz war-risk designation at $10-14 million per voyage while Brent fell 19%, maintaining a structural divergence from futures pricing. Underwriters require a UN Security Council resolution or government certification letter, not diplomatic optimism, before de-listing the strait.

Oman (Sultan Haitham's government)

Muscat issued a mine alert in its own territorial waters while denying any Hormuz toll plan after US Treasury threatened sanctions. A suspected mine in Omani waters on the same weekend as US financial pressure forces Muscat to demonstrate sovereignty without appearing to choose sides.

China (PRC)

Beijing sent scholars rather than its defence minister to Shangri-La for the second year running and addressed Taiwan and multilateralism without mentioning Iran. China maintains its bilateral energy corridor protection with Tehran while refusing the diplomatic exposure of a public position at multilateral forums.

Iran Supreme National Security Council

The SNSC framed the unsigned MOU as a 10-point Iranian victory with enrichment already recognised, and the foreign ministry rejected Trump's nuclear conditions within hours. Tehran treats each unsigned day as validation that Iran has retained its stockpile without surrendering it.

Trump administration (CENTCOM/White House)

Trump posted three non-negotiable public conditions while CENTCOM disabled a commercial ship and Hegseth threatened resumed strikes from Singapore. The administration treats the unsigned MOU as leverage to extract maximum Iranian concessions before any ceasefire instrument is committed to paper.
