Which critical minerals pose the greatest supply chain risk to US manufacturers?

According to the stress test analysis, lithium, cobalt, nickel, and rare earth elements represent the most critical vulnerabilities. These minerals are concentrated in specific regions with limited alternative suppliers, creating geopolitical and operational risks. Processing capacity is equally constrained, with most refinement occurring outside the US, amplifying exposure.

How should companies stress-test their supply chains against mineral shocks?

The Atlantic Council recommends scenario-based modeling that accounts for multi-month supply interruptions, price volatility spikes, and cascading downstream effects. Companies should map mineral dependencies across their product portfolio, identify single-source risks, model inventory buffers needed to weather disruptions, and evaluate technology substitutes or redesigns.

What are the operational implications if a major minerals supplier restricts exports?

A significant export restriction could create 6-18 month supply gaps for dependent industries, forcing production delays, inventory depletion, and margin compression. The impact varies by industry: automotive and renewable energy manufacturers face the highest risk due to concentrated mineral requirements in batteries and components.

What role does government policy play in addressing critical minerals vulnerabilities?

Government initiatives can accelerate domestic mining and processing capacity, establish strategic stockpiles, fund R&D for alternative materials, and create trade agreements with allied suppliers. Supply chain teams should track policy developments closely, as subsidies or tariffs could reshape sourcing economics and competitive positioning.

How can companies reduce critical minerals exposure without operational disruption?

Multi-pronged approaches include: phased diversification of supplier base, investment in material recycling and circular economy practices, product redesign to reduce mineral intensity, strategic inventory buffers for long lead-time materials, and collaboration with industry peers on joint sourcing initiatives.

The signal

The Atlantic Council has published a comprehensive stress test analysis examining vulnerabilities in US critical minerals supply chains, highlighting systemic risks that could cascade across multiple industries. Critical minerals—essential for electronics, renewable energy, defense, and automotive sectors—remain concentrated in geographically isolated suppliers, creating single points of failure. The analysis evaluates how various disruption scenarios (geopolitical tensions, trade restrictions, natural disasters, or processing bottlenecks) would cascade through dependent industries.

For supply chain professionals, this research underscores the strategic imperative to diversify mineral sourcing, establish redundant processing capacity, and build strategic inventories. The US currently depends heavily on imports for materials like lithium, cobalt, and rare earth elements, with limited domestic processing infrastructure. Supply chain teams must now model multiple scenarios and stress-test procurement strategies against realistic shock scenarios rather than historical patterns.

The findings suggest that reactive sourcing strategies are inadequate for the current geopolitical and environmental context. Organizations should immediately assess their mineral dependencies, identify alternative suppliers or technologies, and collaborate with government initiatives to strengthen domestic or allied supply networks. This represents a structural shift requiring investment in forward-looking supply chain visibility and resilience planning.
