Why is there a copper supply gap? Because demand is growing faster than mines can be built. The International Energy Agency projects that copper demand will rise by about 7 million tonnes a year by 2040, the largest increase of any energy mineral, while supply from existing mines and announced projects falls roughly 25 percent short of expected demand by 2035 [1]. New mines take close to two decades to develop, ore grades at existing mines are declining, and the capital needed to bring new supply forward arrives late and from too few sources. There is no shortage of copper in the ground; there is a shortage of copper that can be mined in time.
The demand side
Copper is the conductor in every electrical system, and the next two decades are an electrical buildout. Grids are being expanded to carry new generation and new load. Vehicles are electrifying, and an electric car uses several times the copper of a combustion car. Buildings are being wired for heat pumps and chargers. Data centers, driven by AI workloads, are projected by the IEA to more than double their electricity consumption to around 945 TWh by 2030, and each megawatt of capacity is built from copper-intensive transformers, busbars, cabling and cooling [2]. World mine production was about 23 million tonnes in 2025 [3]; the IEA's projected demand growth alone is close to a third of that.
The supply side
Time. Mines that started producing between 2020 and 2023 took 17.9 years on average from discovery to first output [4]. Demand that arrives in two to five years cannot be met by supply that arrives in eighteen. See how long it takes to build a copper mine.
Grade. The average ore grade in Chile, the largest producer, has fallen about 30 percent over fifteen years [5]. Lower grade means more rock, energy, water and capital per tonne of metal, and it means existing mines produce less over time unless they expand.
Concentration. Chile, the Democratic Republic of the Congo and Peru dominate mining; China refines close to half the world's copper [1][3]. Concentration makes supply vulnerable to policy, export controls and disruption in a handful of places. The United States imports an estimated 57 percent of its refined copper consumption and added copper to its List of Critical Minerals in November 2025 [3].
Capital. The IEA estimates copper needs about USD 310 billion of mining and refining investment by 2040 [1]. The capital is needed earliest, when risk is highest and the number of willing financiers is smallest. Projects that are geologically and technically viable sit unfinanced.
Why price alone does not close it
A higher copper price improves the economics of new projects, but it does not shorten permitting or construction. A price signal today produces a new mine in the late 2030s. In the meantime, higher prices ration demand, push substitution at the margin and reward whoever already holds metal or has secured future supply. That is why industrial buyers increasingly seek direct, long-term supply from producers rather than relying on the spot market when a project reaches electrical fit-out.
Where Toto Finance fits
Toto Finance addresses the capital and market-structure part of the gap. Copper in Future (COPTTR) connects verified reserves entering production with a wide pool of investors and industrial buyers years before first cathode, giving producers pre-production capital and buyers secured supply. Copper Now (COPTT) gives US buyers direct ownership of cathode in a US warehouse with instant settlement. Toto Finance does not own mines; it makes the copper that producers hold verifiable, transferable and financeable. See the copper page and mine to market.
