The US strategic critical minerals reserve has moved closer to physical procurement. On 23 September 2026, Glencore and Mercuria became the first two participants in VaultCo, the independently governed private company implementing Project Vault. Together, the commodity traders committed $1 billion to help procure and stockpile critical minerals for US industry.
The announcement marks a significant step for a programme designed to protect manufacturers from supply disruptions. But the financial commitments should not be confused with completed purchases. Public disclosures do not specify how much material VaultCo has already bought, what its current inventory contains or when deliveries will arrive.
The distinction matters. Project Vault is moving from financial structure towards physical supply. Its ultimate value will depend on the materials it secures and how effectively manufacturers can access them during a disruption.
Project Vault Moves From Financing to Procurement
The Export-Import Bank of the United States (EXIM) approved a direct loan of up to $10 billion for Project Vault on 2 February 2026. The broader programme combines EXIM financing with private-sector capital to establish a reserve of critical raw materials for US manufacturers. The materials will be stored in facilities across the United States.
Glencore and Mercuria bring global sourcing, trading and logistics capabilities to the initiative. Under the arrangement, they will help source, procure and deliver minerals into the reserve. Their participation gives VaultCo access to established commodity-market networks rather than requiring the programme to build those capabilities from scratch.

The $1 billion headline requires a closer look at the financing. The Center for Strategic and International Studies describes the combined commitment from Glencore and Mercuria to VaultCo as $1 billion. Glencore’s announcement identifies a $500 million commitment from EXIM to support its role. Mercuria separately announced a $500 million commitment to Project Vault. These disclosures describe commitments supporting the reserve; they do not establish that $1 billion worth of minerals has already been purchased or delivered.
Project Vault also builds on supplier relationships announced at its launch. EXIM initially named Hartree Partners, Mercuria Americas and Traxys among the suppliers serving the programme. The September announcement therefore marks a new stage in VaultCo’s implementation, not the first involvement of commodity traders in Project Vault.
Commodity Traders Provide the Link to Physical Supply
A strategic reserve requires more than financing. It needs suppliers that can identify available material, negotiate purchases, arrange transport and deliver products that meet manufacturers’ requirements.
Commodity traders already operate across these activities. Their sourcing networks and logistics capabilities can connect producers with industrial buyers. For VaultCo, that offers a route to procure materials through existing commercial channels.
The model also creates a practical distinction between building an inventory and expanding production. VaultCo can buy material already available in the market. It cannot create new mine output or refining capacity simply by placing orders.
The reserve’s market impact will therefore depend on its purchasing decisions. The minerals selected, procurement volumes and timing will determine where its demand enters the market. Those details have not yet been fully disclosed.
Manufacturers Will Determine the Reserve’s Utility
Project Vault is designed to serve the wider US industrial base, rather than only defence requirements. EXIM’s launch announcement identified initial indications of participation from manufacturers including Clarios, GE Vernova, Western Digital and Boeing. The programme aims to provide access to critical raw materials during periods of market disruption.
That purpose makes manufacturer access central to the reserve’s operation. Stockpiled material has limited value as a supply-security measure unless companies can obtain it when normal supply channels fail.
The key operational questions remain: Which materials will VaultCo prioritise? How much will it hold? What conditions will govern access? And how quickly can it deliver material during a disruption?
The public announcements establish the programme’s financing framework and the roles of its initial participants. They do not yet answer all these questions.
Stockpiling Does Not Replace Supply-Chain Diversification
Project Vault can provide a buffer against interruptions in critical mineral supply. It does not, by itself, resolve the structural vulnerabilities that make a reserve necessary.
A stockpile can help manufacturers bridge a temporary shortage. But long-term resilience also depends on a wider network of mines, refineries, processors and qualified suppliers. If processing remains concentrated in a small number of locations, manufacturers can remain exposed when those facilities or trade routes face disruption.
This distinction matters for mining and processing investment. More inventory can improve short-term access to materials. New production and processing capacity can broaden the sources of future supply. The two approaches address different parts of the same risk.
For developers, VaultCo’s procurement activity may create an additional source of demand. However, the scale and distribution of that demand will depend on the minerals it chooses to buy. The announcement alone does not establish which producers or projects will benefit.
The Next Milestone Is Evidence of Physical Inventory
Project Vault has now moved beyond its initial financing announcement. Glencore and Mercuria’s participation gives VaultCo access to established commodity-trading capabilities and a framework for procuring critical minerals.
The next measure of progress will be tangible: confirmed purchases, disclosed inventory composition, delivery schedules and clear arrangements for manufacturers to access stored material.
Those details will show how the programme translates financing into operational supply security. They will also help distinguish the reserve’s immediate role as a buffer against disruption from the longer task of diversifying critical mineral supply chains.
For the US industrial base, Project Vault’s success will not be measured by financing commitments alone. It will depend on whether the reserve can deliver the right materials when manufacturers need them.
