Is the Global Munitions Boom Built on a House of Cards?
While global defense budgets soar, the West's reliance on geopolitical rivals for antimony, tungsten, and propellant precursors threatens to derail the ammunition boom.
Wall Street loves a sure thing, and a projected $66 billion ammunition market by 2031 looks like a titanium-clad guarantee. But peel back the brass casing on this booming defense sector, and you will find a supply chain so precarious it could make a logistics officer weep. The modern munitions industry is entirely beholden to a handful of highly critical minerals and chemical precursors, and the uncomfortable truth is that the West does not control the geopolitical tap.
When we talk about replenishing military stockpiles, we are primarily talking about moving mountains of raw earth. Copper and zinc are alloyed by the metric ton to forge the brass casings that seal firing chambers and extract reliably. But the real friction lies in the niche metalloids. Take antimony, a critical hardening agent for lead projectiles and a non-negotiable chemical component in explosive primers. The United States and Europe are heavily reliant on imports for this toxic but vital element. With China historically controlling roughly half of global antimony production and recently flexing its muscle with stringent export restrictions, Western defense planners are suddenly scrambling to fund domestic mining projects that are years away from breaking ground.
