The global supply chain for critical minerals has spent the last two years in a state of high-alert friction. At the center of this tension is antimony, a brittle, silver-white metalloid that rarely makes mainstream headlines but remains an absolute prerequisite for modern military readiness. As of June 2026, the market is navigating a complex “thaw” in trade relations between Beijing and Washington, yet the underlying structural deficit for Western-sourced antimony remains as tight as ever.
For years, the mining industry operated under the assumption of a stable, if lopsided, global flow. China, which accounts for approximately 61% of global production, provided the bulk of the world’s antimony trioxide. However, the export restrictions initiated in August 2024 and the full ban on shipments to the U.S. in December of that year shattered that complacency. While China’s Ministry of Commerce recently suspended these bans through November 27, 2026, for civilian-use applications, the defense sector is not waiting for the next policy reversal. The race to identify and fund the next generation of Western producers has moved from a strategic preference to a national security mandate.
Antimony Price Trend 2026: The “New Normal” Plateau
The volatility of the past 24 months has redefined what “normal” looks like for antimony pricing. In 2022, the metal traded at roughly $21.62 per kilogram. By the peak of the panic in mid-2025, prices surged past $60 per kilogram in some spot markets: a nearly 300% increase driven by the fear of a total supply cutoff.
As we move through mid-2026, the market has entered a correction phase, though it remains far from pre-crisis levels. The current retail benchmark for investors sits at approximately $51.80 per kilogram. While this represents a ~22% decline from the 2025 highs, it is still structurally significantly higher than the historical average.
| Period | North America Index ($/kg) | Europe Index ($/kg) | Market Status |
|---|---|---|---|
| Jan 2022 | $21.62 | $20.80 | Stable Supply |
| Aug 2024 | $21.56 | $22.40 | Export Ban Announced |
| June 2025 | $60.50 | $58.90 | Supply Crisis Peak |
| Dec 2025 | $34.20 | $38.10 | Post-Suspension Correction |
| June 2026 (Current) | $27.50 | $32.96 | “Firm to Stable” Plateau |
The current price trend in 2026 reflects a “wait-and-see” approach. The temporary suspension of Chinese export controls has allowed some inventory to flow back into North American and European markets, but the upcoming November 2026 deadline creates a hard ceiling on how much prices can deflate. Operators and investors are increasingly looking at critical minerals stocks not just for growth, but as a hedge against the inevitable return of supply-side friction.
Why Antimony Matters for Defense
The primary driver of the “defense squeeze” is the unique chemical properties of antimony. It is essential for the production of primers in small arms and large-caliber ammunition. Without it, the reliability of percussion caps and firing pins is compromised. Beyond ballistics, antimony is a critical hardening agent in lead-acid batteries and is used in flame retardants for military vehicles, uniforms, and aircraft interiors.
Perhaps most crucially for the 2026 outlook, antimony is a key component in infrared sensors and night-vision goggles. As modern warfare increasingly relies on superior optics and electronic warfare capabilities, the demand for high-purity antimony has decoupled from the broader industrial cycle. Even as global manufacturing fluctuates, the defense-driven demand remains price-inelastic. Governments are no longer just monitoring the market; they are active participants through the Defense Logistics Agency (DLA) and strategic stockpiling programs.
High-purity processing capacity remains the primary bottleneck for Western supply chains.
The China Factor: Navigating the Export Control Thaw
The current relative calm in the market is artificial. On November 9, 2025, China suspended its export bans on key minerals, including antimony, destined for the U.S. until late 2026. This move was widely interpreted as a tactical de-escalation intended to provide leverage in broader trade negotiations.
However, for Western defense planners, this “window of ease” is a two-edged sword. While it has lowered spot prices and allowed for some inventory replenishment, it also risks slowing the momentum for domestic mining projects. The market is effectively in a race: can Western projects reach a “Final Investment Decision” (FID) or break ground before the next potential ban in late 2026 or 2027?
Industry analysts note that the price gap between Chinese and international markets is narrowing, but the risk premium remains. Any re-tightening of policy after November 2026 would likely trigger a price spike similar to the $60/kg levels seen in 2025. This volatility makes project valuation and P/NAV analysis essential for investors attempting to pick the winners in the junior mining space.
Western Producer Spotlight: From Permitting to Production
The search for a reliable “Western” unit of antimony leads to a handful of key projects and operators that are currently receiving unprecedented government attention.
1. Perpetua Resources (Stibnite Project, Idaho)
Perpetua Resources remains the most high-profile potential source of primary antimony in the United States. Its Stibnite Gold Project is not just a gold play; it is a critical minerals play that happens to sit on one of the largest antimony reserves outside of China and Russia.
In late 2023 and throughout 2024, the company secured an Ordnance Technology Initiative Agreement (OTIA) worth up to $15.5 million from the U.S. Department of Defense. More importantly, Perpetua has received a Letter of Interest for up to $1.8 billion in financing from the EXIM Bank. In 2026, the focus has shifted entirely to the final stages of permitting. While full-scale production is likely a post-2027 story, the market treats Perpetua as the benchmark for U.S. strategic independence in the sector.
2. United States Antimony Corp (USAC)
As the only dedicated U.S.-listed antimony producer, USAC occupies a unique niche. While its primary mine production has historically been small, its processing and refining capabilities in Montana are vital. USAC has spent 2025 and early 2026 upgrading its facilities to handle a wider variety of feedstock, including recycled materials and concentrate from Western-allied jurisdictions. For defense contractors, USAC represents a domestic “bottleneck-breaker” that can convert raw material into the high-purity trioxide required for military applications.
3. Mandalay Resources (Costerfield, Australia)
While located in Australia, Mandalay’s Costerfield mine is a critical link in the Western supply chain. It is one of the highest-grade antimony-gold mines in the world. In the current 2026 climate, Australian producers are benefiting from “Friend-shoring” policies that prioritize mineral imports from Tier-1 jurisdictions. Mandalay has consistently filled the gap left by Chinese export controls, shipping concentrate to refineries in both Asia and North America.
Underground operations like those at Costerfield are essential for high-grade supply.
The Outlook for 2026 and Beyond
The remainder of 2026 will be defined by the “November Cliff.” As the expiration of China’s export suspension nears, we expect to see a renewed round of defensive buying from both government stockpiles and private defense contractors.
We anticipate that antimony prices will find a firm floor around the $25-$30/kg range for industrial concentrate, with high-purity metal commanding a significant premium. The “firm to stable” outlook is supported by the fact that global supply is still only “adequately supplied” at best. Any disruption: whether from geopolitical shifts in Myanmar or further restrictions in Russia: could easily tip the balance back into a deficit.
For investors and operators, the takeaway is clear: the era of cheap, abundant antimony is over. The “Defense Squeeze” has permanently altered the cost structure of the ammunition and aerospace industries. Identifying the next Western producers isn’t just an exercise in market speculation; it is the fundamental task of securing the defense industrial base for the decade to come.
Strategic management of critical mineral supplies is now a boardroom priority for defense contractors.
