Aluminum Prices Spike as Gulf Conflict Squeezes Supply and Energy Costs, Impacting U.S. Solar Market

Global aluminum markets have entered a sharp upward cycle in 2026 as geopolitical tensions in the Middle East disrupt supply chains and push energy-linked costs higher.

On May 27, 2026, Reuters reported a sharp rise in aluminum prices, which followed disruptions due to conflict in the Gulf region. These issues raised worries about tighter supply and higher production costs. Energy-intensive industries, like solar manufacturing, felt the impact the most.

The scale of the move is significant. LME aluminum prices have risen from the low-$3,000s per ton earlier this year to about $3,600–$3,650 per ton in May 2026. 

Over a broader horizon, prices are now roughly 40–48% higher year-on-year, reflecting sustained tightness rather than a short-term spike. Analysts now describe the market as being driven more by supply shock than demand strength.

Gulf Supply Shock Sends the Global Aluminum Trade Into Deficit

The biggest driver behind the rally is a sudden loss of production capacity in the Middle East. Disruptions linked to the Iran conflict have impacted key Gulf smelters, including facilities in Qatar, Bahrain, and the UAE. These operations make up about 9% of the world’s aluminum smelting capacity, excluding China.

Industry estimates suggest:

• Around 2 million tons of annual production capacity have been disrupted in early 2026.
• Gulf supply equals roughly 7–9% of global output capacity.
• Some facilities may take up to one year to fully recover.

This is not just a temporary logistics issue. It is a direct production shock.

A Reuters analysis called this one of the worst aluminum supply disruptions in decades. It noted that physical shortages are tightening inventories worldwide.

The Strait of Hormuz, a critical energy and metals shipping route, has also seen reduced traffic, increasing freight uncertainty, and insurance costs.

Tight Inventories and Record Premiums Push Prices Higher

Beyond geopolitics, market structure is amplifying the price move. LME data shows aluminum prices recently reaching around $3,655 per ton, the highest level in nearly four years.

This is the second-highest level in over a decade now, after the highest price recorded in March 2022.
