Total copper demand is forecast to grow at an average rate of 2.6% per year to 2035, an increase from 1.9% from 2006-2021, to more than 50 Mt per year by 2050.
A new report by BHP, the world’s largest mining company by market capitalisation, states this demand will be driven by:
- traditional economic growth
- the Energy Transition
- digital demand, primarily data centres
“In absolute terms, this is roughly 1 Mt copper demand growth per year, every year, until 2035 ‒ double the 0.5 Mt annual growth volume of the past 15 years” — BHP Insights: how copper will shape our future
The demand growth split of global copper demand is estimated at:
- Traditional vs Energy Transition vs Digital split around 92% / 7% / 1%
- by 2050, we predict the split to have evolved to 71% / 23% / 6%
For example, BHP expects global electricity consumption for data centres to increase from approx 2% of global demand today, to 9% by 2050. Copper demand in data centres is expected to increase x6 by 2050.
The challenge, as we have highlighted in our own report, warning we face a supply gap of nearly 10 million mt within the next ten years, is supply.
“Against optimistic supply forecasts, which include the development of all probable copper projects, a significant gap to expected demand in 2035 is evident, even with our positive view on copper scrap supply” — BHP Insights: how copper will shape our future
- existing mines are estimated to be producing around 15% less copper in 2035 than in 2024
- the average grade of copper mines has declined by around 40% since 1991
- 30-50% of global copper supply to face grade decline and ageing challenges over the next decade
BHP’s report comes as UBS also warns that increasingly tighter supplies of copper in the coming 6-12 months could lead to a deficit of more than 200,000 tons in 2025, as demand grows for the metal key to energy transition.
And Wood Mackenzie projects demand is expected to outstrip supply.
