US and Iran launch new missile strikes
Fresh fighting between the US and Iran broke out overnight, with missile strikes launched in the Strait of Hormuz.
The new military action sent the Brent crude oil price to US$114 per barrel, its highest level since Russia invaded Ukraine in 2022.
At the time of writing, the copper price is US$5.84 per pound, up 0.85%.
Trading Economics analysts said escalating US-Iran tensions are raising concerns about demand for industrial metals like copper.
The analysts said:
A major downside risk for industrial metals is an extended shutdown of the Strait of Hormuz, which could intensify the energy shock and prompt central banks to adopt a more hawkish policy stance, which may dampen manufacturing output and reduce demand for industrial commodities.
On the supply side, copper stocks in warehouses monitored by the LME are still close to their highest levels since 2013, adding to the bearish outlook.
Big picture for copper
The Iran war is a short-term headwind that threatens to disrupt global industrial production due to fuel supply constraints and higher prices.
However, the bigger picture is that a multi-decade green energy transition is underway, and copper's role in electrification will continue to drive longer-term demand, as nations continue to build all the new infrastructure they need for renewable energy generation.
Copper is used in wiring, electric vehicles (EVs), wind turbines, solar energy systems, telecommunications, and electronic products.
The US added copper to its Critical Minerals List in November last year.
The copper price reached a record high of US$6.60 per pound in January. The red metal traded above US$6 per pound again last month.
With this backdrop in mind, here are four ASX copper shares that are buy-rated by the experts.

financing of Sulphur Springs construction.The resulting financial flexibility would allow DVP to act nimbly on any forthcoming organic and inorganic opportunities.

Copper production missed on lower Tritton grades but this was offset by a solid cost performance and strong cash flow (+72% qoq), materially strengthening the balance sheet and funding flexibility.
Tritton is set up for a stronger 4Q26, while Constellation, Golden Plateau and the Peel acquisition underpin a longer-term production and mine life extension story.
Aeris Resources is in the process of acquiring Peel Mining Ltd (ASX: PEX) to access its South Cobar Copper Project.
