The text below is an edited version of an Insight originally published on CRU Online, dated 2 March 2026. For the full version, contact us here.
The Insight assesses how conflict in the Middle East could affect aluminium and alumina markets. The most acute near-term risk is disruption to shipping and logistics, especially through the Strait of Hormuz. Currently, there is no confirmation of physical damage to production assets. Disruptions to supply could lift aluminium prices and regional premiums quickly, while alumina may find short-term support due to a combination of supply risk and higher energy costs. Over the medium term, broader macro impacts could lead to demand destruction, potentially offsetting initial price strength.
Key points
- There is no confirmed material damage to aluminium smelting assets in the GCC at the time of writing.
- The Strait of Hormuz is highlighted as the central chokepoint; and even without closure, delays and higher shipping costs can disrupt flows.
- The GCC is a major export hub for primary aluminium, making supply to key importing regions vulnerable.
- US and EU + UK markets are notably exposed to GCC-origin primary aluminium shipments, as are other parts of Asia.
- While there has been investment in alumina capacity in the GCC, the region’s smelting operations depend heavily on imported alumina, much of which is historically from Australia, with newer options from Indonesia and Vietnam.
- Alumina inventories at smelters are limited to only a few weeks of supply,so prolonged logistics constraints could force operational responses.
- Rising energy prices (oil/gas) would provide upward pressure to alumina prices through rising operational costs.
- Medium-term risk: A prolonged conflict in the Middle East would have negative impacts for global economic growth, which would lead to demand destruction for aluminium. This would eventually lead to falling prices.
Key risks and potential impacts on trade flows
- Strait of Hormuz disruption (primary risk): Longer waiting times, logistical bottlenecks, and higher insurance/freight could reduce effective availability of GCC metal to importing regions and raise delivered costs/premiums.
- Alumina supply chain vulnerability: Constrained imports could become critical as alumina is not well suited to long storage and smelters typically hold limited inventory cover.
- Limited workarounds: Alternative discharge outside the Gulf (e.g., Oman with overland movement) is possible only for smaller volumes and faces cost/logistics constraints.
- Energy cost pass-through: Aluminium may not need a large price response for profitability, but alumina – already described as loss-making – could see stronger price support from higher energy inputs.
- Demand destruction (medium term): Macroeconomic deterioration could weaken consumption and offset early price rallies.
CRU will continue to monitor the conflict in the Middle East over the coming days and note developments in our Aluminium services with more detail of what it might mean for casthouse and rolled product markets, given the key exports from the region. To gain access, contact us here.
