The US Export-Import Bank’s proposed stockpiling initiative would initially source critical minerals from anywhere in the world, including China, an official involved in the project has revealed.
The $12 billion Project Vault would later shift to a replenishment model that prioritizes domestic production first, followed by allied nations and other sources as a last resort, executives including Ex-Im Chief Banking Officer Brian Greeley said Wednesday unveiling some of the first details publicly announced on the project. Greeley spoke alongside representatives of Glencore Plc. and Hartree Partners LP, which will be among trading houses procuring materials for Vault.
The project aims to build an immediate buffer against critical mineral supply shocks while using future purchases to send a stronger demand signal to US and friendly-nation producers.
Vault — which combines about $2 billion in private capital with a $10 billion Ex-Im loan — is President Donald Trump’s latest effort to build an alternative supply chain for the materials, which are key for the production of electric vehicle batteries, solar panels and other low-carbon technologies. China is the dominant supplier of critical minerals worldwide.
The recent panel was the most robust public discussion of Vault since Ex-Im revealed the program in February. For nearly three months, metals investors, traders and consumers have sought details as the government worked behind the scenes to flesh out the project.
Attendees packed a conference room at a hotel in Washington, DC, to get details on Vault’s sourcing hierarchy and payment structure. The program’s so-called waterfall would give preference to domestic suppliers even when their material comes at a premium to allied alternatives, with participating manufacturers expected to accept that trade-off as part of joining the program, panelists said.
The initial stockpile fill, however, would be driven chiefly by availability, reflecting the reality that some of the roughly 60 minerals under consideration are produced only in limited geographies and, in some cases, remain heavily influenced by China.
Vault is being structured as a demand-driven vehicle rather than a government-directed stockpile, according to panelists. Manufacturers would determine which minerals are stored, with the program then work with traders to secure supply. It’s designed to give US firms more leverage in opaque and fragmented markets where individual buyers often struggle to source smaller volumes efficiently or at transparent prices.
On storage, Greeley said the project will begin by relying on warehouse networks already controlled by trading partners and procurement providers. Over time, Vault is expected to develop its own storage network, either by building facilities or leasing them. A mature system could combine its own sites with third-party warehouses.
Panelists said the use of specialist traders would also be tailored to individual metals. Rather than sending orders into an open bidding process, Vault is expected to match procurement to firms with expertise in specific markets, allowing traders with relationships in cobalt, rare earths or other niche material sectors to handle those flows. The goal, panelists said, is to preserve pricing discipline, improve execution and avoid creating a scramble for hard-to-find materials.
