The current geopolitical and economic environment is best understood as a fragile system approaching an oxygen constraint. In simple terms, an oxygen constraint occurs when a system depends on something so essential that it is normally invisible—until there isn’t quite enough of it. The human body provides a useful analogy. At normal oxygen levels, everything functions seamlessly, then with a small reduction, performance drops noticeably and we hit a tipping point where any further decline causes basic functions to fail. Importantly, the shortage does not need to be absolute to have serious effects, even modest constraints can trigger disproportionate disruption.
Our current industrialized economies operate in much the same way. They are highly complex, tightly coupled systems optimized for efficiency—not resilience. They depend on a continuous flow of critical inputs that are largely taken for granted during normal conditions. Like oxygen, these inputs only become noticeable when they are constrained—at which point performance deteriorates rapidly and, if unresolved, systems begin to break down.
Critical minerals (non-fuel materials or elements essential to a national economy or security) sit at the center of this dynamic. They underpin energy systems, digital infrastructure, advanced manufacturing and modern defense capabilities. Broadly, this group of materials is hitting a major constraint—not in-ground availability, but instead it is the limited capacity of the global industrial system to develop new mines, extract high-quality ore and process raw materials into usable forms at the scale and speed now required. Declining ore grades, long development timelines and a lack of new large-scale projects mean that supply cannot respond quickly to rising demand. Making it likely that even immediate and significant capital investment is unlikely to resolve these bottlenecks in the near to medium term.
This structural fragility is compounded by the concentration of midstream processing capacity, particularly in China. Over the past two decades, China has built dominant positions across refining and processing for a wide range of critical minerals while also securing upstream access through global mining investments. This has created a system in which much of the world depends on a single node for transforming raw materials into usable inputs. This position can be leveraged for strategic purposes, effectively turning a commercial dependency into a geopolitical constraint.
The degree of this dependency is clear and measurable. As illustrated in the recent United States Geologic Survey (USGS) figure below, the US remains highly reliant on foreign sources for many critical minerals, with a significant concentration of supply tied to a small number of countries—most notably China. This concentration highlights a key vulnerability to localized disruptions or politically driven hoarding.
Demand for these materials is also accelerating across multiple fronts. Electrification, renewable energy deployment, artificial intelligence infrastructure, robotics and the rearmament of the global defense-industrial base are all scaling simultaneously. Each of these trends is highly material-intensive and together they represent a step-change in demand.
The ongoing conflict involving Iran has intensified these pressures by disrupting commodity flows and trade routes, increasing input costs and accelerating defense consumption. Beyond the current pressures, the conflict is better understood as a catalyst than a root cause. It is compressing timelines within an already fragile system, exposing the extent to which military capability and economic stability are now tied to material throughput. Modern warfare is revealing itself to be a contest not just of technology, but materials access, inventory depth and supply chain endurance.
Governments are increasingly responding to these constraints by shifting away from purely market-based mechanisms toward more interventionist, security-driven approaches. In the United States, initiatives such as strategic stockpiling and supply chain financing—supported by institutions like the Export-Import Bank of the United States—reflect an effort to stabilize access to key materials and reduce exposure to external dependencies. Public-private partnerships with firms such as Boeing and GE Vernova further signal a broader realignment of industrial policy toward resource security.
The economic consequences of this shift are likely to be both inflationary and structurally constraining. Material scarcity raises input costs across industries, while tariffs and trade frictions increase the burden on domestic consumers and producers.
In defense terms, the implications are immediate. Many critical minerals—such as rare earth elements and specialty metals—are essential for modern weapons systems and cannot be easily substituted. Rearmament is no longer simply a function of budgetary commitment but is increasingly bound by industrial capacity and material availability.
We’re seeing broader evidence of a global economy that is transitioning from a model optimized for efficiency and scale to one increasingly shaped by resilience, constraint and protectionist fears. Supply chains are being reconfigured with governments taking a more active role in resource procurement, security and allocation. Commodities are being revalued as strategic assets rather than purely cyclical ones.
The central insight is that modern economic and military power ultimately rests on physical throughput. As demand accelerates and supply systems struggle to keep pace, critical minerals are emerging as the limiting factor—the “oxygen” of the industrial world. When that oxygen thins, even slightly, the effects are nonlinear, and the system as a whole becomes more fragile, more volatile and more constrained.
