Iran strikes Gulf aluminium plants

Iranian missiles hit two of the Gulf's largest aluminium smelters, opening an economic warfare front beyond hydrocarbons for the first time in the conflict.

Key takeaway

Iran opened a second economic front targeting Gulf industrial production beyond oil and gas.

IRGC missiles and drones struck Emirates Global Aluminium (EGA) at Al Taweelah in Abu Dhabi and Aluminium Bahrain (Alba) on 28 March 1. These are the first attacks on non-energy industrial targets since the war began. EGA's Al Taweelah site produced 1.6 million tonnes of cast metal in 2025, roughly 4% of global aluminium output and nearly half the Gulf region's capacity. Two Alba workers were injured; EGA reported multiple casualties, none fatal 2.

The IRGC classified both plants as "industries affiliated with and connected to US military and aerospace sectors," applying dual-use targeting logic to civilian commodity production. The classification opens an elastic category: aluminium feeds aerospace, defence manufacturing, packaging, and construction. Iran has moved beyond attacking energy infrastructure to disrupting the industrial supply chains that feed Western defence contractors.

Iran's stated rationale is retaliation for US-Israeli strikes on Iranian steel plants. The effect is broader than the justification. If EGA's damage proves production-grade, the aluminium supply shock will ripple through sectors with no direct connection to hydrocarbons. Brent Crude settled at $112.57 on 28 March ; aluminium futures have not yet priced in the EGA and Alba damage.

In 1991, the US struck Iraqi power plants and water treatment facilities under dual-use logic. Iran is now applying the same doctrine in reverse against US-allied industrial assets. Once established, dual-use targeting expands until one side runs out of targets or the other exhausts its strike capability.

Deep Analysis

In plain English

Iran has been striking oil infrastructure in the Gulf since the conflict began. On 28 March it attacked something different: two of the world's largest aluminium factories, one in the UAE and one in Bahrain. Aluminium might seem an odd target in a war. Iran's stated logic is that these factories supply Western defence industries, so they count as military targets. Critics call this a stretch: the same argument could apply to almost any factory. The practical significance is that two factories producing roughly 4% of the world's aluminium are now damaged or offline. That disrupts everything from aircraft manufacturing to drinks cans. It also signals that no Gulf industrial site is off-limits.

Deep Analysis
Root Causes

Iran's decision to cross from energy to industrial targeting reflects a calculated assessment that energy-only strikes have not produced sufficient economic pressure on Gulf states hosting US forces.

The IRGC's dual-use classification creates an elastic legal category that can encompass virtually any Gulf industrial asset. Aluminium feeds aerospace, defence manufacturing, packaging, and construction globally. Once the classification is established, the target set is essentially unlimited.

Iran also faces internal political pressure to demonstrate symmetry. US-Israeli strikes on Iranian steel plants (cited by the IRGC as justification) created a domestic demand for visible retaliation against comparable targets rather than further attacks on oil infrastructure that risks global backlash.

What could happen next?
  • Precedent

    IRGC's dual-use classification creates a template applicable to virtually any Gulf industrial asset, effectively removing the distinction between military and civilian economic targets.

    Short term · 0.8
  • Risk

    If EGA production damage proves sustained, aluminium futures will enter supply-shock territory, adding a second commodity market disruption alongside oil.

    Immediate · 0.7
  • Consequence

    Gulf sovereign risk premia will rise as host states face broader industrial targeting; UAE and Bahrain may reconsider the terms of US basing access.

Different Perspectives
China
China
Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.
Israel
Israel
IDF Chief Zamir said on 3 June there is no ceasefire for his forces even as Israel signed the Washington Lebanon framework requiring Hezbollah withdrawal south of the Litani; a UNIFIL peacekeeper was killed by mortar near Marjayoun on the same day, exposing the gap between the diplomatic framework and a ground advance that has not stopped.
Bahrain
Bahrain
The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.
Qatar
Qatar
Qatar offered $6bn under OFAC Licence L-2 restrictions and sent Ghalibaf's delegation home empty-handed; the $6bn ceiling is a legal constraint, not a negotiating floor, and Rubio's no-sanctions-relief testimony means Qatar cannot revise it without White House action that has not been requested.
Kuwait
Kuwait
Kuwait expelled two Iranian diplomats within 24 hours of the airport strike, the strongest and fastest Kuwaiti diplomatic move of the conflict, while keeping the full mission in place to preserve a communication channel; it has now invoked Article 51 self-defence, filed a formal protest, and expelled diplomats, exhausting its formal toolkit short of full rupture.
United States
United States
Trump narrated a weekend deal while the channel Rubio described under oath, Khamenei's written-only couriers with a 3-to-5-day lag, cannot answer at that speed; CENTCOM called the airport strike deliberate, calculated and unjustified. The House 215-208 vote gave Congress its first on-record war-powers position against the deployment Trump has run without a signed instrument for 96 days.
