Houthis threaten second chokepoint

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

Trump administration

Washington defends the MATCH Act as closing a loophole that lets ASML's DUV tools reach Chinese fabs indirectly, dismissing the Dutch Cabinet's June complaint of being treated with disregard. Officials expect the bill's progress through Congress to keep the DUV cross-subsidy question live regardless of ASML's Q2 numbers.

Bruegel

Brussels-based economists argue this week's deliverables, specialist fab aid and a digital euro that restricts no US firm, prove Europe's sovereignty agenda advances only where it meets no American resistance. They expect the leading-edge fabrication gap and dependence on US frontier AI models to persist absent a policy that directly confronts a named US interest.

German federal government

Berlin welcomes the €659m tranche funding jobs across North Rhine-Westphalia, Schleswig-Holstein, Hesse and Bavaria, on top of the ESMC Dresden fab already under construction on TSMC-shipped tooling. Officials treat power and analogue capacity as the achievable near-term win while Dresden remains Germany's only bet on leading-edge logic.

House of Commons Science, Innovation and Technology Committee

The committee's 7 July report found the UK has "no coherent strategic framework" for sovereign technology and warns it "risks being cut off at whim", citing the June order that barred foreign access to Anthropic's Fable 5 and Mythos 5 as the trigger case. It expects no domestic hyperscaler or foundry response before the gap widens further.

European Commission

The Commission cleared €659m in German state aid on 14 July, taking cumulative Chips Act support to roughly €14.2bn, and let the digital-euro mandate reach trilogue after ECON's floor-vote shortcut was overturned. Brussels presents both as sovereignty delivered, without addressing that neither funds leading-edge logic fabrication.

ASML

ASML raised FY2026 guidance to €43-45bn on 15 July and, for the first time since Q1, dropped the export-control hedge from its release even with the MATCH Act live in Congress. Fouquet frames the order book, 86 systems against 67 in Q1, as strong enough to outrun the DUV dispute rather than evidence it has cooled.
