The Trump Administration’s Project Vault is positioning itself as a strategic safeguard for America’s industrial future. Backed by $1.67 billion in private capital and a $10 billion loan from the U.S. Export-Import Bank, the initiative aims to build a reserve of critical minerals equivalent to 60 days of demand.
The objective is straightforward: protect industries such as automotive and renewable energy from supply disruptions and price volatility. However, based on current pricing and projected 2026 demand, the cost is anything but small.
The $991 Million Battery Question
At today’s prices, securing 60 days of key battery minerals (lithium, cobalt, nickel, manganese, graphite, and petroleum coke) would cost approximately $991 million.
Lithium would represent the largest share of that total.
That figure reflects only battery inputs. And it assumes current pricing levels hold into 2026, an assumption that investors know can change quickly in commodity markets.
What Is Project Vault?
Project Vault is designed as a strategic stockpile. These reserves address short-term supply emergencies by holding physical inventory that can be released when markets tighten.
As described, the initiative intends to “absorb sudden supply disruptions by releasing physical material” while providing “confidence to key domestic industries that some emergency supply is available within US borders if needed.”
The model closely mirrors the Strategic Petroleum Reserve, which was established after the 1973 oil embargo and still holds hundreds of millions of barrels of crude oil.
In effect, Project Vault would act as a form of insurance policy, an option-like buffer for U.S. industry.
Who’s Participating?
Major commodities trading houses including Hartree Partners, Mercuria, and Traxys have agreed to procure minerals for the stockpile.
Downstream participation is equally notable. Companies such as General Motors, Stellantis, Boeing, Google, and GE Vernova have committed to participate.
Under the framework, participating companies would pay a fee in exchange for the right to draw from the reserve during defined emergencies – specifically when they cannot source material through traditional markets.
The Copper and Rare Earth Multiplier
Battery minerals are only part of the equation.
Benchmark Minerals estimates that securing 60 days of U.S. refined copper demand in 2026 would cost an additional $3.7 billion at current prices.
Rare earth materials used in permanent magnets would add another $235 million.
Altogether, the U.S. critical minerals list includes 60 materials. It remains unclear whether Project Vault intends to stockpile all of them, or whether 60 days will be the universal benchmark.
If copper and rare earths are included, the reserve’s total capital requirement expands meaningfully beyond the initial $991 million estimate.
The Strategic Limits
While a reserve may soften short-term shocks, it does not address structural supply concentration.
A U.S. strategic reserve “does not tackle the underlying issue of upstream supply concentration.” Instead, policy measures to “derisk domestic and other ex-China projects and improve bankability” are required alongside reserve-building.
In other words, stockpiles buy time, but they do not create mines, refineries, or processing capacity.
Project Vault should be viewed as one tool among several. Other measures could include export restrictions, tariffs, local content requirements, upstream funding, equity investments, and government-backed offtake agreements.
There is also a geopolitical nuance. Sources have warned that without “clear guidance and transparent sourcing,” the U.S. reserve itself risks dependency on Chinese supply chains – particularly for rare earths, where China maintains dominant market control.
The Investment Takeaway
At minimum, Project Vault signals that critical minerals have moved firmly into national security territory.
A 60-day buffer for battery materials alone approaches $1 billion. Add copper and rare earths, and the figure climbs sharply. Yet the larger takeaway for investors may be what this reveals about future policy direction.
Strategic reserves can stabilize markets in the short term. But over the long term, capital allocation into upstream projects, refining capacity, and supply chain diversification will likely determine who benefits most.
Project Vault may be an insurance policy. The broader mineral strategy, however, is still being written.
