Copper Needs $332B in New Mines as 2028 Shortage Looms

Copper could enter a structural mine-supply deficit from 2028 even as refined metal production remains sufficient in the near term. BloombergNEF estimates the industry needs $332 billion in new mine investment as global demand rises 61% to nearly 46 million tonnes by 2050.

MONTREAL (Scrap Monster): The global copper industry may require approximately $332 billion in new mine investment to avoid a structural supply shortage that could begin as early as 2028, even as refined copper production is expected to exceed consumption over the next two years.

Global copper demand is forecast to rise 61% between 2026 and 2050 to nearly 46 million tonnes, according to BloombergNEF's Transition Metals Outlook 2026.

If new mine supply fails to keep pace, the market could face a shortfall of approximately 20 million tonnes by 2050, equivalent to about 44% of projected global demand.

Near-Term Refined Surplus Masks Longer-Term Mine Risk

The long-term warning contrasts with the International Copper Study Group's latest near-term outlook.

ICSG forecasts a refined copper surplus of approximately 104,000 tonnes in 2026, increasing to about 368,000 tonnes in 2027.

The difference reflects two distinct measures of copper supply.

ICSG compares refined copper production with refined copper usage, while BloombergNEF examines whether underlying mining capacity will be sufficient to meet longer-term demand.

That means additional smelter and refinery capacity can keep refined metal available in the short term without solving a shortage of mined feedstock further upstream.

Copper Deficit Could Begin in 2028

BloombergNEF expects copper supply to begin falling short of demand in 2028.

The deficit is projected to widen to approximately 3 million tonnes by 2035, equivalent to around 8% of projected consumption.

By 2050, the gap could reach approximately 20 million tonnes, or 44% of expected global demand.

Copper demand is forecast to grow about 34% by 2035 as electrification expands across transportation, power networks, data centres and other copper-intensive applications.

Declining Ore Grades Add to Supply Challenge

Copper supply faces structural constraints beyond simple investment levels.

Declining ore grades mean miners must process more material to recover the same quantity of copper, increasing energy use, operating costs and project complexity.

At the same time, insufficient exploration investment has limited the pipeline of major new deposits capable of replacing depleted production.

Permitting requirements, infrastructure needs and large upfront capital commitments further complicate efforts to bring new mines online quickly.

New Copper Mines Take About 17 Years to Develop

BloombergNEF estimates that a new copper mine takes an average of approximately 17 years to reach production.

That long development timeline means investment decisions made today will help determine copper availability well into the 2030s and beyond.

Even if sufficient capital is committed, permitting, engineering, construction and technical challenges can delay production for years.

Electrified Transport Demand Set to Surge 244%

Electrified transport is expected to become one of the largest sources of incremental copper demand.

Copper consumption in the sector is forecast to rise 244% to approximately 11.4 million tonnes by 2050.

Demand will come not only from electric vehicles themselves, but also from charging systems, power infrastructure, batteries and wider grid expansion.

Copper Stands Apart From Other Transition Metals

Copper is the principal long-term supply exception among the 10 materials examined in BloombergNEF's outlook.

The research firm expects the other nine materials studied — aluminum, cobalt, graphite, lithium, manganese, nickel, platinum, palladium and steel — to have sufficient long-term production capacity through 2050, provided producers continue replacing depleted reserves and developing planned projects.

That makes copper a potentially more significant constraint on electrification than several battery materials that have attracted greater investment attention in recent years.

Refining Concentration Creates Another Supply Risk

The report also identifies vulnerabilities further downstream in the metals supply chain.

Eight of the 10 materials studied have more than half of global refining capacity concentrated in a single country.

China holds that dominant refining position in seven of those markets.

Such concentration leaves supply chains exposed to trade restrictions, geopolitical tension and changes in industrial policy.

For governments seeking to diversify critical-mineral supply chains, expanding mining capacity alone will not be enough. New refining, processing and related infrastructure will also require substantial investment.

Recycling Will Become Increasingly Important

BloombergNEF also expects recycled material to play an increasingly important role in balancing long-term metals markets.

Six of the 10 materials covered in the outlook will require recycling to meet projected demand by 2035, rising to eight by 2050.

For copper, higher recovery rates from end-of-life products, electrical infrastructure, vehicles and industrial equipment could help supplement mined supply, although recycling alone is unlikely to eliminate the projected mine deficit.

Market Read

The copper market is therefore facing two different supply stories at the same time.

In the near term, stronger smelter output and secondary refined production could keep the refined market in surplus through 2027.

Beyond that period, however, mine supply becomes the larger concern. Smelters cannot create copper concentrate that has not been mined, and a limited pipeline of new projects could eventually constrain refined production as well.

The industry's ability to secure financing, permits, construction capacity and new discoveries over the next several years will help determine how severely copper availability constrains electrification in the 2030s and beyond.
