Critical Minerals: Securing the Inputs of the Digital Economy

What are critical minerals? Critical minerals are non-fuel minerals and materials that are essential to the economy or national security, that have supply chains vulnerable to disruption, and whose absence would have significant consequences. Which minerals qualify is decided by governments. The United States added copper to its official List of Critical Minerals on November 7, 2025, alongside materials such as lithium, cobalt, nickel, graphite, tin and the rare earth elements [1]. The common features are concentrated supply, long development timelines and demand that is rising faster than new mines can be built.

Why critical minerals matter now

Four demand drivers are converging. Electricity grids are being expanded and reinforced to carry more renewable generation and more load. Transport is electrifying, and each electric vehicle uses far more copper, nickel, lithium and rare earths than a combustion vehicle. Defense and aerospace systems depend on specialty metals. And artificial intelligence is adding a new source of demand: the IEA projects that electricity consumption by data centers will more than double to around 945 TWh by 2030, and every megawatt of that capacity needs copper in transformers, busbars, cabling and cooling systems [2].

The IEA's Global Critical Minerals Outlook 2026 concludes that supply for several key minerals is not keeping pace. For copper, existing mines and announced projects are projected to fall roughly 25 percent short of expected demand by 2035, with about USD 310 billion of mining and refining investment needed by 2040 [3].

Copper: the first critical mineral for Toto Finance

Copper is the conductor in every electrical system, and no other material can replace it at scale. World mine production was an estimated 23 million tonnes in 2025 and refined production about 29 million tonnes. Chile (5.3 million tonnes), the Democratic Republic of the Congo (3.2 million tonnes) and Peru (2.7 million tonnes) led mine output; China refined about 14 million tonnes, close to half the world total [1]. The United States relied on imports for an estimated 57 percent of its refined copper consumption in 2025 [1].

New copper supply is slow. Mines that started production between 2020 and 2023 took 17.9 years on average from discovery to first output [4], and the average ore grade in Chile has fallen by about 30 percent over fifteen years, so more rock, energy and capital are needed for every tonne of metal [5]. Copper is the commodity where the gap between physical importance and financial infrastructure is widest, which is why Toto Finance starts here. The copper page covers the market in depth and tokenized copper explains the mechanics.

Other critical minerals

Toto Finance's infrastructure is designed to be commodity-agnostic. The minerals below are described for context; Toto Finance does not currently operate products in them and does not imply projects in any of these categories.

Rare earth elements

Seventeen metallic elements used in permanent magnets for wind turbines, electric motors and defense systems, and in catalysts, lasers and electronics. Mining and, above all, separation and refining are highly concentrated geographically. Rare earths trade in oxide and metal form with limited transparent benchmarks, which makes verification and pricing the first challenges for any digital ownership structure.

Lithium

The lightest metal, essential to lithium-ion batteries for vehicles and stationary storage. Produced from brines in South America and hard-rock spodumene in Australia and elsewhere, then converted into carbonate or hydroxide. Lithium prices have been volatile, and the chemical products are less standardized than exchange-traded metals.

Nickel

Used in stainless steel and in the high-energy cathodes of many electric vehicle batteries. Supply is concentrated in Indonesia, the Philippines, Russia and a few other producers. Class 1 nickel is deliverable on the LME, which gives it the pricing transparency that many battery minerals lack.

Cobalt

A by-product of copper and nickel mining used in battery cathodes, superalloys and magnets. Most mined supply comes from the Democratic Republic of the Congo, and most refining occurs in China. Cobalt is LME-deliverable and has recognized responsible-sourcing frameworks, both relevant to verification.

Tin

The solder of the electronics industry and a component of lead-free solders, coatings and alloys. Supply is concentrated in China, Indonesia, Myanmar and Peru, and tin is LME-deliverable. Toto Finance's retail marketplace has historically listed tin among its metals.

Graphite, manganese and other battery materials

Natural and synthetic graphite anodes, manganese for cathodes and a range of specialty metals round out the battery supply chain. Verification frameworks and pricing benchmarks are still developing for many of them.

The supply chain security problem

Critical mineral supply chains share three weaknesses.

1. Concentration. Mining and, more acutely, processing and refining are concentrated in a small number of countries, so a policy change, export restriction or logistics disruption in one place affects the whole market.
2. Capital. The projects that would diversify supply need capital earliest, when risk is highest and the number of willing financiers is smallest. Commodity financing explains the traditional instruments and their limits.
3. Opacity. Ownership of material in the ground, in production and in transit is recorded on paper across many parties, so buyers cannot easily verify provenance and financiers cannot easily verify collateral.

Governments are responding with critical minerals lists, stockpiles, permitting reform, offtake guarantees and financing programs. Industrial buyers are responding by seeking direct, long-term supply relationships with producers.

Where digital ownership infrastructure fits

Toto Finance's mine-to-market platform addresses the second and third weaknesses directly. Verified reserves and scheduled production can be connected with a materially larger pool of capital than royalty, streaming and trade-finance channels reach. Provenance, verification and ownership are recorded once and carried with the material from mine through refining to delivery, giving buyers a verifiable chain of custody and financiers real-time visibility of collateral. Industrial buyers can secure future supply as transferable digital claims and take physical delivery when the material is due.

Copper is the first application. The same infrastructure is designed to extend to other critical minerals as verification standards, pricing references and custody arrangements allow.
