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

South Korean financial markets

South Korea, which imports virtually all its crude oil, is absorbing the war's economic transmission most acutely among non-belligerents. The second KOSPI circuit breaker in four sessions — with Samsung down over 10% and SK Hynix down 12.3% — reflects an industrial economy unable to reprice energy costs that have risen 72% in ten days. The market response indicates Korean industry cannot sustain oil above $100 per barrel without margin compression across manufacturing, semiconductors, and shipping.

Migrant worker communities in the Gulf

The first confirmed civilian deaths in Saudi Arabia — one Indian and one Bangladeshi killed, twelve Bangladeshis wounded — fell on communities with no voice in the military decisions that placed them in harm's way. Migrant workers live near military installations because that housing is affordable, not by choice. Bangladesh and India face the dilemma of needing to protect nationals who cannot easily leave a war zone while depending on Gulf remittances that fund a substantial share of their domestic economies.

Azerbaijan — President Ilham Aliyev

Aliyev treats the Nakhchivan strikes as a direct act of war against Azerbaijani sovereignty, placing armed forces on full combat readiness and demanding an Iranian explanation. The response is calibrated to maximise international sympathy while stopping short of military retaliation — Baku cannot fight Iran alone and needs either Turkish or NATO backing to credibly deter further strikes.

Oil-importing nations (Japan, South Korea, India)

The Hormuz closure is an existential threat. Japan, South Korea, and India receive the majority of their crude through the strait — they will bear the heaviest economic cost of a war they had no part in.

Global South governments (Indonesia, Brazil, South Africa)

Neutrality was possible when the targets were military. 148 dead schoolgirls made it impossible — no government can explain that away to its own citizens.

Turkey

Has absorbed three Iranian ballistic missile interceptions since 4 March without invoking NATO Article 5 consultation. Each incident narrows Ankara's political room to continue absorbing without Alliance-level response.
