Insight Focus
Aluminium fundamentals have clearly tightened over the past month. Global inventories remain low, with LME stocks continuing a multiyear decline. Analysts increasingly expect a global aluminium deficit in 2026, versus modest surplus expectations late last year.
The past month reinforced a key theme for aluminium markets in 2026: fragmentation. Prices are being driven less by global balance alone and more by geopolitics, regional logistics, carbon policy and arbitrage constraints.
Aluminium packaging demand remains structurally supportive, but converters face mounting cost pressures. Into Q2, volatility is expected to stay high, with premiums, scrap spreads and regional arbitrage offering the clearest price signals rather than LME alone.
Supply growth outside China remains constrained by energy costs, capital discipline and permitting, while demand is supported by electrification, EVs, renewable energy and packaging. ING and regional banks warn that even partial prolongation of Gulf outages could push deficits toward 1–2 million tonnes, keeping prices and premia elevated through mid‑year.
Aluminium Prices Rally on Geopolitical Supply Shock
Global aluminium prices strengthened sharply over the past month, driven primarily by supply disruptions in the Middle East and elevated geopolitical risk premia. Three‑month LME aluminium traded largely in the USD 3,300–3,550/tonne range, rising more than 2% month‑on‑month and up nearly 50% year‑on‑year.
The US-Israel attacks on Iran are not helping the situation. There have been reported outages at Emirates Global Aluminium (EGA)’s Al Taweelah smelter after a hit by Iranian missiles. In addition, smelter Aluminium Bahrain (Alba) has reportedly reduced capacity to 30% from over 80%.
Both of these events, combined with earlier curtailments at Qatalum would reduce Middle East capacity by around 3 million tonnes/year – about half of all production in the region.
This has created some opportunity for China, as several analysis firms have increased aluminium export volume growth projection for the country to between 5% and 18%. This is up from flat to slightly negative projections prior to the war.
Risk, Logistics Reprice Metal
Physical aluminium premiums became increasingly volatile. The Japan Q2 2026 benchmark premium jumped 79% to USD 350/tonne, reflecting Asia’s exposure to Middle East supply and its role as the regional price setter.
Even prior to the war, S&P reported supply constraints for P1020 aluminium due to several shutdowns of major smelters. Outages at South32’s Mozal Alcantara in Mozambique and Century Aluminum’s Norðurál Grundartangi in Iceland will remove several hundred thousand tonnes of aluminium – primarily from the EU market.
US Midwest premiums remained historically elevated. According to ING, US consumers have been destocking and supply is extremely tight. There are also concerns raised by Project Vault, which is a US government initiative to build a stockpile of strategic metals, which includes aluminium. Increased US buying would create even tighter conditions in the US market.
Trade Flows Reconfigure Amid Arbitrage Opportunities
Trade flows over the past month have been shaped by three forces: Gulf disruption, tariff structures and carbon policy. Middle East exports have effectively been stranded by risk in the Strait of Hormuz, forcing consumers in Europe and Asia to seek alternative supply.
China, constrained by its 45-million-tonne primary aluminium production cap, has continued to import scrap and secondary metal, tightening global availability of clean scrap grades and supporting secondary aluminium premia. Meanwhile, arbitrage between Europe and the US has narrowed, as softening European premiums reduce incentives to ship metal eastbound across the Atlantic.
Packaging Demand Holds Firm Despite Input Cost Inflation
Aluminium packaging demand remained resilient over the past month, underpinned by food, beverage, pharmaceutical and personal care usage. Packaging accounts for around 60% of aluminium foil demand, with global foil consumption continuing to grow despite higher metal costs.
Sustainability continues to favour aluminium over plastics, with brands accelerating adoption of infinitely recyclable, mono-material packaging formats, particularly in Europe where regulatory pressure is increasing. However, cost inflation is resurfacing as a risk. Higher aluminium prices are squeezing margins for can makers and converters, especially where pass‑through mechanisms lag spot prices.
