DRC and Zambia's Copper: The Strategic Arithmetic Behind Africa's EV Battery Supply Chain
The Democratic Republic of Congo and Zambia together produce over 12% of global copper — a share that puts them at the centre of the energy transition. At approximately $9,420 a tonne, the economics of African copper are being rewritten.
Copper is at approximately $9,420 per tonne on the LME, down $180 on the week and 1.87% lower over five sessions, with a weekly range of $9,380 to $9,680. The DRC and Zambia together account for more than 12% of world production, and the Central African Copperbelt is the only significant source of new supply outside South America.
The demand case is unusually specific for a commodity. An electric vehicle uses roughly three to four times the copper of an internal combustion car, and grid expansion to carry renewable generation uses more again. Neither of those is a cyclical demand story that reverses with a recession; both are build-outs with a decade or more of committed capital behind them.
What stands between the ore and the market is infrastructure, and this is where the arithmetic stops being about metal. Copperbelt production is landlocked. It reaches a port either through the Durban corridor, which is long and congested, or through the Lobito corridor to the Angolan coast, which is shorter and has been the subject of substantial recent international investment for exactly that reason. The corridor question determines the delivered cost, and the delivered cost determines whether a mine is competitive at $9,420.
Power is the second constraint. Copper smelting is electricity-intensive, and both countries depend heavily on hydroelectric generation that has been constrained by drought in recent years. A mine that cannot run its smelter exports concentrate instead of metal, which captures a fraction of the value. The difference between the two is worth more to Zambia's export earnings than a several-hundred-dollar move in the price.
For an investor the distinction between the metal and the producers is sharp here. LME copper is a clean bet on the energy transition. A listed Copperbelt producer is a bet on the transition, plus the transport corridor, plus the power supply, plus the mining code of the country it operates in — which in the DRC has been rewritten within the past decade. Those are different risks on different timescales, and they should be sized differently.
