The global critical minerals market has entered a period of deceptive calm in mid-2026, but beneath the surface of range-bound pricing, a structural deficit in antimony is beginning to re-emerge. Following the extreme volatility of 2025, which saw prices for the niche industrial metal spike to over $40,000 per tonne, the current "silent squeeze" is driven by a unique convergence of expiring trade suspensions, high-intensity defense procurement, and the accelerating transition to high-efficiency solar glass.
While commodities like copper and gold often dominate headlines, antimony has quietly become one of the most strategically sensitive elements in the Western supply chain. As of June 19, 2026, market participants are closely watching a critical deadline: the scheduled expiration of China’s export ban suspension in November. This looming policy shift, combined with a lack of new Western primary production, has set the stage for a second-half price breakout.
The Geopolitical Stalemate: China’s Leverage in 2026
China remains the undisputed gravity center for the antimony market, accounting for approximately 61% of global production and a significantly higher share of refined purity. In late 2024 and throughout 2025, Beijing implemented stringent export controls on "dual-use" materials, which included antimony and its related compounds. These controls were partially suspended in early 2026, allowing international markets to rebalance and providing a temporary reprieve from the 2025 price peak.
However, the suspension is not a permanent lifting of the ban. The Ministry of Commerce in Beijing has indicated that the current window for exports to the United States and Europe is set to be reviewed by November 27, 2026. This has created a bifurcated market where Western industrial buyers are racing to build inventories before a potential "hard" re-imposition of export quotas.
"The market is currently in a holding pattern," notes one senior analyst at a London-based commodities consultancy. "Supply from Southeast Asia and Tajikistan has increased slightly, but it is not nearly enough to offset a renewed Chinese restriction. We are seeing a structural dependency that cannot be solved by 2026 alone."
Defense Demand: The Ammunition Bottleneck
Antimony’s primary strategic role in 2026 is its application in the defense sector. It is an essential hardening agent for lead bullets and shrapnel, a key component in primers for explosives, and a vital ingredient in infrared sensors and flame retardants for military equipment.
The ongoing replenishment of global ammunition stockpiles has placed a floor under antimony demand that did not exist five years ago. US and NATO-aligned defense contractors have scaled up production lines for 155mm artillery shells and small arms ammunition, all of which require reliable streams of antimony trioxide.
Furthermore, new US defense procurement rules now strictly mandate that critical minerals used in munitions must eventually be sourced from non-adversarial nations. This has created a "defense premium" for antimony sourced outside of China, leading to a significant price gap between domestic and international spot prices.
The Energy Nexus: Solar Glass and Battery Storage
Beyond defense, the "silent squeeze" is being amplified by the rapid growth of the photovoltaic (PV) industry. Antimony is used as a de-fining agent in the production of high-clarity solar glass. As solar capacity installations continue to break records in 2026, the demand from glass manufacturers has become a massive, non-discretionary buyer in the market.
In the battery sector, while lithium and nickel remain the focus of the energy transition, antimony is seeing renewed interest in liquid metal batteries for grid-scale storage. These long-duration energy storage systems (LDESS) are being deployed to stabilize renewable energy grids, and their high antimony intensity per megawatt-hour represents a significant future demand lever that analysts believe is not yet fully priced into the 2026 outlook.
Market Snapshot: Antimony Price Trends and Forecasts
The following data highlights the shift from the pre-crisis era to the current "silent squeeze" of June 2026.
| Period | Average Price (USD/kg) | Market Condition | Primary Driver |
|---|---|---|---|
| 2020 (Historical) | $5.90 | Over-supplied | Stable industrial use |
| June 2025 (Peak) | $42.50 | Acute Shortage | China Export Restrictions |
| June 2026 (Current) | $33.80 | "Silent" Squeeze | Pre-Nov 2026 Stockpiling |
| 2027 (Projected) | $39.00 – $46.00 | Structural Deficit | Defense & PV Glass Growth |

Supply Side Realities: The Search for New Tonnage
The challenge for the 2026–2030 period is that bringing new antimony mines online is a slow and capital-intensive process. In the United States, Perpetua Resources continues to advance its Stibnite Gold Project in Idaho. While primarily known for its gold reserves, Stibnite contains one of the largest antimony deposits in the Western Hemisphere. The project has received significant backing from the US Department of Defense, highlighting the urgency of establishing a domestic "mine-to-metal" supply chain.
However, Stibnite is not expected to reach commercial production until late in the decade. In the interim, the market is looking toward junior producers and recycling initiatives. Secondary recovery from lead-acid battery scrap remains a vital source of supply, but it is currently limited by the efficiency of collection networks and the purity requirements of high-tech and defense end-users.
2026 Outlook: Risks and Strategic Positioning
For operators and investors, the second half of 2026 presents a high-stakes environment. The primary risk remains the geopolitical "wild card" of Chinese trade policy. If the export suspension is allowed to lapse in November without a clear replacement, a sudden supply shock could mirror the price action seen in early 2025.
Conversely, if Western nations successfully build a coordinated strategic stockpile, the "squeeze" may remain silent, manifesting as a slow, persistent upward drift in prices rather than a vertical spike.
Key Factors to Watch:
- Chinese Ministry of Commerce Announcements: Any language regarding the renewal or tightening of dual-use export permits before November 2026.
- US Defense Logistics Agency (DLA) Activity: Increased solicitations for antimony trisulfide or trioxide for the National Defense Stockpile.
- Substitution Trends: Monitoring whether flame retardant manufacturers are successfully shifting toward halogen-free alternatives to reduce cost pressures.
As we move toward the final quarters of 2026, the antimony market remains a prime example of the "new normal" in critical minerals: a landscape defined not by abundance, but by strategic scarcity and geopolitical leverage.
