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

Greek shipping registries

Flag states dominating the tanker fleet await the EU's 15 July cap-freeze vote. A formula unlock toward $75 would loosen the ceiling squeezing insurance and crewing costs on their registered hulls.

US money managers

NYMEX WTI managed-money net long fell 23% to +64,041 in the week to 7 July, trimming length into the rally on doubt the Hormuz premium survives without freight or war-risk confirmation.

European refiners (ARA)

ARA refiners are capturing an $80/bbl US diesel crack as Russian gasoil loadings collapsed to 234kbd before Novak's 31 July export ban even bites, widening the arbitrage straight into refining margins.

OPEC+

The seven-member group confirmed a fourth consecutive 188kbd August hike on 5 July, defending market share even though Saudi Arabia's $108-111/bbl breakeven means every added barrel costs Riyadh revenue it cannot recoup.

Indian refiners

Refiners kept lifting discounted Urals as the India/Baltic split widened past $9-10 a barrel on 7 July. A wider Urals-Brent gap means cheaper feedstock locked in against Baltic buyers.

Russia

Urals traded $48.95-55.12 on 12-13 July, below Moscow's $59 budget floor even as Brent gained $6. Oil and gas fund roughly 30% of federal revenue, and Novak's diesel export ban is rationing a shrinking export base.
