Aluminium Hits Seven-Week High on Supply Risks

Benchmark three-month aluminium on the London Metal Exchange climbed to $3,336.50 per metric ton on August 10, 2026, its highest level since June 23. By 1600 GMT, the contract was up about 1.3% on the day, trading around $3,323 per ton. The price strength marked aluminium’s highest level in almost seven weeks and underscored the momentum that has built in recent sessions.

The August 10 move continued a pattern of steady gains, with aluminium rising for a sixth straight session. This winning streak highlighted sustained buying interest and growing concern about the balance between supply and demand in the market.

The latest price advance came against a backdrop of ongoing draws in exchange aluminium inventories. Market commentary linked the continued depletion of stocks to tighter availability for buyers, reinforcing upward pressure on prices. Lower visible inventories often heighten sensitivity to any new supply disruptions or demand surprises.

With inventories trending down, participants increasingly focused on the ability of the supply chain to respond to shifts in consumption. The combination of thin stockpiles and firm pricing signalled a market more vulnerable to external shocks, helping sustain the recent rally.

Geopolitical developments around the Strait of Hormuz added another layer of support to aluminium and broader commodity markets. Iranian officials stated that reopening the key waterway would depend on conditions being met by Washington, dimming prospects for a near-term agreement to restore normal traffic.

These tensions pushed oil prices higher and kept regional supply risks elevated. While aluminium is not produced in the Strait itself, disruptions or perceived threats to shipping in a major energy and trade corridor can reverberate across industrial commodities, reinforcing risk premiums and bolstering prices.

The alignment of shrinking exchange inventories and heightened geopolitical risk created a supportive environment for aluminium on August 10. The metal’s six-session rally and seven-week price high illustrated how quickly sentiment can shift when physical tightness coincides with external threats to supply routes.

In this context, aluminium’s performance served as an indicator of broader industrial metals resilience amid uncertainty. The latest price action suggested that traders and end-users are positioning for a market in which both fundamentals and geopolitics could keep volatility and risk premiums elevated in the near term.
