Aluminium Loses Its War Premium as Copper’s Supply Squeeze Deepens

Aluminium is giving back its Middle East war premium, but copper is telling a different story about the risks facing global commodity markets.

The divergence exposes a critical difference between the two metals: aluminium supply is responding to higher prices, while copper faces mounting constraints at the mine level and growing uncertainty over where available metal will ultimately flow.

According to Standard Chartered’s latest analysis, aluminium prices have returned to pre-conflict levels as production recovers in the Middle East, China increases output and European smelters restart. Copper, meanwhile, remains supported by supply disruptions, US tariff uncertainty and uneven exchange inventories.

For physical traders, the message is clear. A decline in geopolitical risk pricing does not necessarily mean supply chains have returned to normal.

Aluminium Finds Replacement Supply, but Logistics Risks Remain

Aluminium prices have fallen sharply from their 2026 highs, briefly closing below $3,000 per tonne on the London Metal Exchange on October 14 and 15. The reversal reflects a market increasingly confident that additional supply can offset losses caused by the conflict.

China is central to that adjustment. Domestic aluminium production reached 31.1 million tonnes in the first eight months of 2026, up 3.9% year on year. Chinese exports of unwrought aluminium and semi-finished products also rose 25.9% year on year in September to 656,000 tonnes.

Indonesia’s expanding capacity and the restart of European smelters are adding to the supply response.This is how commodity markets absorb shocks: higher prices encourage production, redirect trade flows and bring marginal supply back online. The adjustment, however, comes with limits.

China’s primary aluminium capacity is officially capped at 45 million tonnes annually, while the recovery of Gulf production remains uncertain. Disrupted shipping through the Strait of Hormuz, elevated freight costs and alternative-route constraints continue to complicate the return of Middle Eastern metal to international markets.

The distinction between available production and deliverable metal remains important. Aluminium can lose its headline war premium even as regional physical premiums stay elevated, reflecting differences in local availability, transport costs and import dependence.

For buyers, cheaper LME prices do not automatically translate into cheaper delivered metal.

Copper’s Problem Is Supply Concentration, Not Just Geopolitics

Copper faces a different set of constraints. Standard Chartered expects prices to average $13,674 per tonne in 2026, having raised its forecast amid persistent supply risks and uncertainty over potential US tariffs on refined copper imports.

Mine production is struggling to keep pace with the market’s demands. Chile’s copper output fell 12.8% year on year in August to its lowest monthly level since February 2011. Production was down 7.8% in the year to date, increasing pressure on an already constrained supply chain.

At the same time, exchange inventories are becoming increasingly fragmented. COMEX stocks have climbed to record levels as traders position around US tariff uncertainty, while LME inventories have declined and Chinese spot demand has strengthened.

This geographical imbalance matters. Metal accumulating in the United States is not necessarily available to buyers in Europe or Asia without additional costs and trade flows. Tariff expectations can therefore tighten supply in one region even when headline inventories appear comfortable elsewhere.

Copper also has a demand story that aluminium currently lacks to the same degree. Investment in artificial intelligence infrastructure, power grids and electrification supports longer-term consumption, although weaker global growth, a stronger dollar and tighter monetary policy remain downside risks.

The broader lesson for commodity traders is that price direction alone reveals little about the health of a physical market. Aluminium demonstrates how quickly additional production can unwind a geopolitical premium. Copper shows how mine constraints, policy uncertainty and inventory geography can keep prices elevated even when the wider macroeconomic environment turns less supportive.

As the conflict reshapes trade flows, the key question is no longer simply whether supply has recovered. It is whether the right metal is available in the right place, at the right price.
