Six Development Banks Set Joint Critical Minerals Financing Plan

Six of the world’s largest multilateral development banks have set out a joint framework for critical minerals financing that aims to move resource-rich developing countries beyond digging up raw ore and into processing, refining and manufacturing. The participants are the African Development Bank Group, the Asian Development Bank (ADB), the European Bank for Reconstruction and Development (EBRD), the European Investment Bank Group, the Inter-American Development Bank Group and the World Bank Group. The framework attaches no headline dollar figure to that ambition.

The ADB published the document on 15 October 2026. The banks announced it jointly yesterday, and Reuters reported on it today. It puts into practice a joint statement the six institutions issued in April 2026.

Processing is where the leverage sits. According to the International Energy Agency (IEA), the top three refining countries’ average share rose from about 82% in 2020 to 86% in 2024, so any credible effort to spread that capacity matters to investors and governments alike.

Here is which financing tools are actually on the table, where the economics still fall short, and what to watch before any of this becomes bankable projects.

What the six banks are putting on the table for critical minerals financing

The ambition is broad. The framework covers exploration, mining, processing, refining, manufacturing, recycling and related services. Yet there is no aggregate commitment behind it.

Instead, the banks will identify projects for joint preparation, co-financing, guarantees, insurance and technical assistance. The substance is in the toolkit, and each tool targets a specific risk that keeps private capital away:

• Guarantees and insurance: shield investors from political, currency and construction risk
• Joint project preparation: turns concepts into bankable proposals through shared feasibility, legal and environmental work
• Co-financing and parallel financing: provide scale no single lender could carry
• Blended or concessional finance, where justified: covers public-good infrastructure that cannot earn commercial returns
• Patient capital and offtake support: ease revenue and buyer uncertainty

The framework also bundles power, transport, water, digital and logistics with processing sites in a corridor approach, and pushes harmonised environmental and social standards so sponsors avoid repeating due diligence for each lender. Corridor finance is already in motion: the US International Development Finance Corporation (DFC) approved a loan of up to US$553 million for the Lobito Atlantic Railway in November 2024, and the Atlantic Council put total investment by key partners in the wider Lobito corridor at around US$6 billion.

Platform, not a fund The framework commits no single dollar total. It is a mechanism for preparing and de-risking individual deals.

For you as an investor, that means judging the framework by the projects it brings to financing, not by a pledge total.

Why refining stayed out of reach, and whether finance alone can fix it

The barriers stack up quickly.

1. Energy: refining is electricity-hungry. The Democratic Republic of Congo (DRC) has struggled to move beyond cobalt hydroxide, an intermediate product, partly because unreliable power made further processing uneconomic.
2. Scale: a 2025 analysis cited roughly US$500 million per plant in some segments.
3. Offtake: banks want long-term buyers, while buyers hesitate to sign with unproven producers.
4. Logistics: mines, power, ports and refineries must operate as one system.
5. Skills: technical expertise, technology and regulatory capacity remain thin.

Finance can help with power, logistics, preparation and offtake. It cannot easily erase China’s accumulated advantage.

Concentration in refining capacity matters more than mining rights, because a country can hold world-class deposits and still depend on others to turn that ore into usable material.

Concentration check China leads refining for 19 of 20 strategic minerals at an average share of about 70%, and handles around 91% of rare-earth separation and refining (IEA, 11 September 2026).

The trend has deepened. The IEA found roughly 90% of refined-supply growth from 2020 to 2024 came from the single largest supplier: Indonesia for nickel, China for cobalt, graphite and rare earths. Demand is also moving fast, with lithium demand up nearly 30% in 2024 against about 10% annual growth in the 2010s.

The case that finance is not enough

Resources for the Future (RFF) and the London School of Economics’ Viet Nguyen-Tien argue diversified processing may stay costlier than Chinese supply, needing demand guarantees, subsidies or procurement rules. RFF also flags oversupply that could undercut non-Chinese plants.

Indonesia’s nickel export ban drew in smelters, but with high emissions and heavy reliance on Chinese firms. Concessional money could equally prop up carbon-intensive or uneconomic projects.

This tells you bankability hinges on offtake and energy costs more than capital, so projects lacking secured buyers and reliable power stay risky even with development bank backing.

Risks and signposts: what to watch before the framework becomes bankable projects

The risks are concrete:

• Sovereign debt and contingent liabilities if prices fall or traffic disappoints
• Governance and rent capture without transparent contracts and revenues
• Environmental and community harm from energy- and water-intensive processing
• Slow approval cycles at the banks
• Continued dependence on Chinese capital, equipment or offtake

Brookings warns corridors such as Lobito and Simandou need secondary roads, industrial zones and processing, or they become export railways. It estimated Lobito’s completion need at up to US$2.4 billion and Simandou’s rail and port needs at least US$6 billion. IPIS recorded Lobito-related pledges of US$455 million from Angola, US$100 million from the DRC and US$1 billion from Zambia.

Policy friction persists. The November 2025 G20 declaration in South Africa welcomed only a voluntary, non-binding framework on local beneficiation. CEPR economists have warned of a new resource curse, and IIED notes trade rules can constrain local-processing requirements.

Signposts to watch

1. First named joint projects
2. First guarantee or insurance deals
3. Signed offtake agreements
4. Alignment of environmental and social standards
5. The working group’s first annual report to the Heads of MDBs Group

Guarantees and offtake deals carry the most information for private investors. Given annual reporting, expect progress to be measured in years. The practical move is to watch for named projects with secured power and offtake rather than reacting to the announcement itself.

What lenders demand before committing capital, from secured offtake to credible power supply, is the practical test that any project emerging from the framework will still have to pass.

What the framework changes, and what it leaves unresolved

The framework treats critical minerals as an integrated infrastructure, finance and industrial policy problem, a meaningful shift from financing isolated mines. What remains open is significant: no committed capital, a persistent cost gap against Chinese processing, and questions over how quickly the banks can deliver.

Treat it as a de-risking signal that becomes meaningful only as named projects, guarantees and offtake deals appear.
