Key takeaway

Iran activated the Houthis after talks collapsed, threatening a second chokepoint.

Ansar Allah fired a barrage of ballistic missiles at military sites in southern Israel on 28 March, their first attack since the war began on 28 February. 1 The IDF intercepted one missile; sirens sounded in Beersheba.

Houthi military spokesman Brigadier-General Yahya Saree announced the strikes via Al Masirah TV and stated they would continue "until the aggression against all fronts of the resistance ceases." 2 The Houthis had sat out the war's first four weeks at Tehran's request. Their entry is a reversal, and its timing is deliberate: it came the day after Pakistan confirmed indirect US-Iran talks had stalled and the day Iran published five conditions for ending the war, including sovereignty over the Strait of Hormuz .

Tehran chose this moment to activate the proxy it had held in reserve. The military threat from a single intercepted missile is secondary. The strategic threat is geographic: combined with Iran's existing traffic control at Hormuz, where only five vessels crossed on 25 March , two of the world's three critical maritime chokepoints are now contested simultaneously for the first time since the 1973 oil crisis.

Deep Analysis

In plain English

Iran has a network of armed groups across the Middle East it funds and supplies. The Houthis, who control northern Yemen, are one of these. Since the war began on 28 February, they had stayed out of the fight at Iran's request. On 28 March they fired their first missiles at Israel. One was shot down; air raid sirens went off in the southern Israeli city of Beersheba. The Houthi spokesman said they would keep firing until all attacks on their allies stop. Why does this matter beyond one intercepted missile? Because the Houthis sit on the coast next to a second major oil shipping route called Bab al-Mandeb. Iran already controls the Strait of Hormuz. If both routes come under threat at the same time, the world's energy supply faces a problem no emergency reserve can fix.

Deep Analysis
Root Causes

The Houthis' decision calculus has two structural drivers the body does not address. First, Israeli strikes in August-September 2025 destroyed Houthi command-and-control, leaving the group with missiles but no officers who could plan integrated operations . Tehran has spent the war's first four weeks rebuilding that coordination layer, which explains the delay.

Second, the Houthis are politically incentivised to enter regardless of Iranian instructions. Sitting out a war that kills co-religionists in Gaza and Lebanon while the group claims to be the region's most committed resistance force is a legitimacy problem. Iranian restraint and Houthi domestic politics were converging toward the same outcome.

What could happen next?
  • Risk

    If the Houthis close Bab al-Mandeb, the IEA's 400 million barrel reserve release cannot compensate; two chokepoints cannot be substituted simultaneously.

    weeks · High
  • Consequence

    Houthi entry invalidates the US ceasefire framework; any deal must now cover four fronts, not two.

    days · High
  • Precedent

    Iran has demonstrated it can hold proxies in reserve then activate on diplomatic cue, making proxy networks a coercive bargaining tool rather than a standing threat.

Different Perspectives
Turkey (Shakarab consideration)
Turkey (Shakarab consideration)
Ankara serves as one of two Western-adjacent Iran back-channels while Turkish national Gholamreza Khani Shakarab faces imminent execution on espionage charges in Iran. President Erdogan cannot deflect the domestic political crisis that a Turkish execution would trigger, which would force suspension of the mediating role.
Germany (Bundestag gap)
Germany (Bundestag gap)
Belgium, Germany, Australia, and France committed Hormuz coalition hardware on 18 May. Germany's Bundestag authorisation for the coalition deployment remains pending, creating a constitutional gap between the commitment announced and the parliamentary mandate required to operationalise it.
IEA and oil market analysts
IEA and oil market analysts
The IEA's $106 May Brent projection met the market in one session on 20 May as Brent fell 5.16% on diplomatic optimism. Goldman Sachs and Morgan Stanley's two-layer premium framework holds: the kinetic component compressed; the structural insurance component tied to Lloyd's ROE remains unresolved.

Documented the dual Kurdish execution at Naqadeh on 21 May, the two Iraqi-national espionage executions on 20 May, and Gholamreza Khani Shakarab's imminent execution risk. The 24-hour cluster covers two executions at one facility, the first foreign-national espionage executions, and a Turkish national whose death would suspend Ankara's mediation.

Hull rates stand at 110-125% of vessel value on the secondary market; the Joint War Committee has conditioned cover reopening on written ROE from the coalition or PGSA. The Majlis rial bill makes any compliant ROE structurally impossible to draft while the PGSA's yuan portal remains its operational mechanism.
United Kingdom and France (Northwood coalition)
United Kingdom and France (Northwood coalition)
The 26-nation coalition paper requires Lloyd's to see written rules of engagement before Hormuz war-risk cover reopens. The Majlis rial bill adds a second governance incompatibility on top of the unpublished PGSA fee schedule; coalition ROE cannot mention rial without conceding Iranian sovereignty over the strait.
