Why Copper Prices Are Falling While Aluminum Surges

3. A stronger U.S. dollar
Because most commodities are priced in dollars, a stronger dollar makes copper more expensive for buyers using other currencies. Recent dollar strength linked to inflation and monetary policy expectations has contributed to copper pulling back from earlier record highs.

4. Geopolitical growth fears
Concerns that conflict in the Middle East could slow global growth have also hurt copper demand expectations. Analysts at J.P. Morgan noted that geopolitical risks and higher energy prices could push copper prices down toward $11,100–$11,200 per ton in bearish scenarios.

Taken together, these factors mean copper is currently trading more like a macroeconomic indicator than a supply‑driven commodity.

Aluminum: a supply shock story

Aluminum’s market dynamics are currently very different. Instead of weakening demand, investors are focusing on tightening supply risks.

Citigroup analysts say the metal may have its most bullish supply setup in more than 50 years, driven by disruptions and structural shortages in the aluminum market.

Middle East disruptions and the Strait of Hormuz

A major risk centers on supply chains connected to the Persian Gulf. Shipping routes through the Strait of Hormuz, one of the world’s most critical energy and commodities chokepoints, could face disruption from geopolitical tensions. If traffic through the strait is restricted, aluminum production and exports from the region could be significantly affected.

Some producers in the Gulf have already faced operational disruptions and force majeure declarations, which can tighten physical supply and push prices higher.

Falling inventories and tightening physical markets

At the same time, global aluminum inventories have been declining while physical availability tightens. This combination—lower inventories, production disruptions, and logistical risk—has shifted aluminum into a supply‑driven rally rather than a demand‑driven one.

Citigroup argues the market is beginning to price in a structural deficit. The bank has described aluminum as entering a structural bull phase driven by constrained supply and recovering demand.

Price forecasts for aluminum

Citigroup’s outlook reflects the strength of the supply story:

• The bank sees a credible path toward $4,000 per metric ton in the near term if supply disruptions continue.
• In the longer term, Citi has raised its 2027 average aluminum price forecast to about $3,500 per ton.

These projections imply that aluminum could outperform many other industrial metals if supply remains tight.

Why the copper–aluminum divergence matters

The contrast highlights how differently industrial metals respond to market forces:

• Copper: dominated by macro demand signals—growth, construction activity, interest rates, and currency strength.
• Aluminum: currently driven by physical supply risks and geopolitical disruption.

In other words, copper is reacting to fears about the global economy, while aluminum is reacting to fears about whether enough metal will be available.

If global growth weakens further, copper could remain under pressure. But if Middle East supply risks intensify or inventories keep falling, aluminum could continue to outperform other base metals in the near term.
