Inside the Copper Supply Problem

Copper Supply Is Tightening
Global copper demand is about 28 million tonnes per year today. Most long-term forecasts point to 40–42 million tonnes by 2040, which means the system needs to add roughly 12–14 million tonnes of new annual supply over the next 15 years.
That’s not a small adjustment. It’s the equivalent of building multiple large-scale mining regions from scratch.
What’s driving demand
Copper demand is increasing because more of the economy is running through electrical systems.
Power demand is rising globally, and copper sits directly inside that. Every increase in generation, transmission, or distribution requires more copper in cables, transformers and infrastructure.
Electric vehicles increase intensity. A standard combustion vehicle uses roughly 20–25 kg of copper. Electric vehicles use closer to 60–80 kg. That difference compounds as production scales into tens of millions of units.Renewables push the same direction. Wind and solar systems require more copper per unit of energy than traditional sources, particularly when you include the grid upgrades needed to connect them. Data centres add another layer. They don’t replace existing demand — they sit on top of it. More computing requires more power, and that power runs through copper-heavy systems.
None of these trends are short-term. They are built into how infrastructure is now designed.
Why supply doesn’t keep up
Supply moves slowly for reasons that don’t change quickly.
A new copper mine typically takes 10–15 years from discovery to production. That includes exploration, approvals, financing, construction and ramp-up. Even under good conditions, timelines stretch.
Existing mines are becoming less efficient. Ore grades are declining, particularly in major producing regions like Chile. Lower grades mean more rock has to be processed to produce the same output, which raises costs and limits growth. Production is also concentrated. A large share of global supply comes from a small number of countries, which adds political and operational risk into the system.
Recycling contributes, but it’s limited. It depends on available scrap, and even in optimistic scenarios it covers only 25–30% of demand. The rest has to come from new mining.
What the gap looks like
When you line up demand growth with supply constraints, the gap becomes visible over time. Demand continues to rise steadily. Supply increases, but then begins to flatten as existing mines mature and new projects fail to keep pace. By 2040, that leaves a gap of roughly 10 million tonnes per year in many projections.
What slows new supply
Even when prices rise, supply doesn’t respond quickly.
Higher prices can justify new projects, but they don’t reduce timelines. Mines still take years to build. Permitting still takes time. Infrastructure still needs to be developed.
There are also practical constraints:
longer approval processes
environmental restrictions
capital intensity
execution risk on large projects
Most new mines also come online slower than expected. Delays and cost overruns are normal, not exceptional.
Where pressure shows up first
The system doesn’t break all at once. It tightens.
That usually shows up as:
smaller supply buffers
more sensitivity to disruption
gradual upward pressure on costs
Short-term deficits start to appear. Prices respond, but not in a straight line. The underlying issue isn’t price - it’s timing.
Key numbers
~28 Mt current demand
~40–42 Mt projected demand by 2040
~12–14 Mt additional supply required
10–15 years to develop a new mine
60–80 kg copper per EV vs ~20–25 kg for ICE vehicles
~25–30% supply from recycling
~10 Mt potential annual supply gap by 2040
What matters
The copper market isn’t short because of one factor.
Demand is increasing across multiple parts of the economy. Supply is slow to expand and getting harder to scale. That gap builds over time and while it does, thier are opptuntinies.
