Executive Summary

The global tungsten market has entered 2026 in extreme volatility, driven by China's implementation of export controls on tungsten products following US trade disputes. This supply shock exposes a critical structural vulnerability in Western defense industrial bases: approximately 90% of the world's tungsten flows through Chinese channels, while China accounts for approximately 75% of worldwide mine production. The convergence of accelerating defense budgets and constrained tungsten supply creates a strategic crisis that threatens allied military readiness and technological superiority.

1. Extreme Price Volatility Signals Structural Supply Crisis

Tungsten concentrates are currently trading at around 22,000-24,000 USD/MTU, with APT breaking the 450 USD mark and powder prices climbing to 55,000 USD/t, an increase of over 500 percent since the 2024 lows. Given depleted inventories, restricted Chinese exports and limited near-term new supply, this volatility is widely expected to persist throughout 2026. Analysts predict a 4-6% CAGR in price levels as the defense and aerospace industries enter a new cycle of procurement.

2. Defense Budget Expansion Directly Amplifies Tungsten Demand Pressure

Global defence spending grew in 2025, reaching USD2.63 trillion, up from USD2.48 trillion in 2024, with spending rising in real terms by 2.5%. FY 2026 achieved a historic $1 trillion overall defense topline, and FY 2027 proposes $1.15 trillion in discretionary (28% increase) and $350 billion in mandatory bringing total resources for defense to $1.5 trillion. Tungsten consumption linked to defense applications such as helicopters, fighter jets and ammunition could increase 12% this year.

3. China's Export Controls Create Weaponized Supply Leverage

China's Ministry of Commerce announced on February 4 last year that export controls would be applied with immediate effect to certain forms of tungsten, including APT, following a US announcement of tariffs on Chinese imports. Since China put tungsten export controls in place in February 2025, Chinese tungsten APT exports have entered a license-based phase, causing the export volume of tungsten APT to fall almost 70% from 782 tonnes in 2024 to 243 tonnes in the first 11 months of 2025. The combined capacity of major non-Chinese producers represents less than 15% of global demand, highlighting the structural supply gap that China export controls on tungsten exploit.

4. Processing Bottlenecks Concentrate Chinese Control Beyond Raw Materials

Ammonium paratungstate production represents the critical bottleneck in tungsten supply chains, requiring specialised chemical processing equipment with corrosion resistance, environmental compliance systems, and technical expertise in tungsten chemistry and purification. China's processing dominance in tungsten refining represents approximately 85% of global capacity, creating bottleneck control that extends beyond raw material extraction to include technical expertise.

5. Allied Defense Industrial Base Resilience Initiatives Remain Nascent and Underfunded

The Pentagon plans to spend up to $1 billion on critical minerals stockpiling, with tungsten among the materials that the US Defense Logistics Agency was said to have been looking at purchasing. In 2025, the Department of Defense announced its intent to procure up to $1 billion in stockpile materials. However, Almonty Industries is ramping up the Sangdong mine in South Korea with Phase 1 in production, and plans the US launch of "Gentung Browns Lake" in the second half of 2026: the first commercial US tungsten mine in decades, funded with 219 million USD, a fraction of defense budget scale.

Strategic Analysis

The Demand-Supply Mismatch: A Structural Crisis

With reindustrialization and defense spending accelerating in the U.S. and elsewhere, tungsten demand is set to grow, and BMO expects the metal's supply challenges to keep it firmly in the spotlight of critical minerals strategies for years to come. Yet new mine developments in Europe, the US and Asia remain years away from entering supply chains. This temporal mismatch creates a critical vulnerability window: defense procurement cycles operate on 2-5 year timelines, while tungsten supply diversification requires 5-15 years.

CICC forecasts a global deficit of 20,000 MTU by 2028, as demand explodes from defense, semiconductors, EV batteries, and AI data centers. This supply gap directly threatens production of armor-piercing munitions, hypersonic vehicle components, and advanced semiconductor fabrication, all central to NATO capability targets.

China's Strategic Leverage: From Commodity to Geopolitical Weapon

Tungsten continues to behave like a strategic resource rather than a conventional industrial metal - its pricing increasingly influenced by policy decisions, strategic stockpiling and geopolitical alignment. The regulatory framework demonstrates understanding that Western governments cannot rapidly develop alternative supplies due to environmental regulations, capital requirements, and technical expertise concentration in Chinese facilities, with mine development and processing infrastructure typically requiring 5-15 years for full operational capability.

Following Japan's political dispute with China over Prime Minister Takaichi Sanae's November remarks concerning Taiwan, China's Ministry of Commerce issued a new announcement prohibiting exports to Japan of dual-use items destined for military end users, with tungsten-related products such as ammonium paratungstate (APT), tungsten oxide and tungsten carbide included in the controlled list. This demonstrates China's willingness to weaponize tungsten access against specific allies, not merely as broad trade leverage but as targeted coercion.

Allied Defense Industrial Base Response: Coordination Without Scale

NATO has recognized the crisis. NATO and Allies will identify risks related to critical manufacturing capability, supply chain capacity and bottlenecks, and key materials and components, across the Alliance and among partners, as appropriate; explore the establishment of multinational stockpiling initiatives for specific critical raw materials; and leverage the NATO innovation ecosystem to enhance resilience of the supply chain for critical materials and technologies.

Allies agreed to take action to foster the responsiveness, strength, resilience and security of supply chains in order to protect industries and ensure that the Alliance develops military capabilities free from the hostile influence of potential adversaries, with the Hague Summit decision to allocate 1.5% of GDP to critical infrastructure, civil preparedness, and the defence industrial base.

However, this coordination framework lacks enforcement mechanisms and capital commitment. Supply-side interventions are insufficient without parallel attention to demand-side anchors across the mine-to-manufactured-goods supply chain, a mine without a refinery, a refinery without a manufacturer, and a manufacturer without a customer are each stranded assets.

Cross-Domain Cascade: Financial, Geopolitical, and Military Implications

Financial Intelligence Lens: Processed critical minerals are foundational to the U.S. defense industrial base, directly enabling military readiness and technological superiority, embedded across nearly all major defense systems, from aircraft and munitions to naval platforms, communications, and surveillance. Price volatility creates budget uncertainty for multi-year procurement programs. By framing price volatility as a national security concern rather than a market anomaly, the EO signals a shift toward using trade policy to stabilize prices and sustain industrial capacity, rather than relying solely on market forces.

Geopolitical Leverage: China controls the global supply chain for numerous critical minerals, with China controlling 95% of global output of heavy rare earths, and this control provides Beijing with the ability to weaponize these supply chains, threatening to disrupt our defense industrial base and compromise military readiness in a crisis. Tungsten export controls represent a rehearsal for broader critical minerals weaponization.

Military Readiness Risk: The price elevation reflects not merely reduced volume but the absence of meaningful substitutes for specialised applications, defense contractors cannot easily switch to alternative materials for armour-piercing ammunition, and aerospace manufacturers require tungsten strategic importance for turbine blade applications.

Strategic Implications for U.S. and Allied Defense Industrial Base Resilience

Immediate Vulnerabilities (2026-2027)

1. Ammunition Production Constraints: Of the $150 billion in mandatory Defense spending, $113 billion is expected to be allocated within Fiscal 2026, representing a 22% year-over-year increase in weapons spending, returning the share of the DOD budget allocated to weapons spending to the 45% level last seen during the Reagan administration. Yet tungsten supply cannot scale to support this procurement surge.

2. Semiconductor Manufacturing Risk: The semiconductor industry's dependence on tungsten creates additional vulnerabilities across technology supply chains, with tungsten serving as metallisation layers within advanced process nodes (7nm, 5nm, 3nm), where chemical vapour deposition systems employ tungsten precursors that cannot be easily substituted without fundamental redesign of process chemistry and equipment calibrations.

Medium-Term Mitigation Pathways (2027-2032)

In 2026, federal investment will moderate-to-high confidence expand beyond rare earth elements to include other high-risk minerals like antimony and tungsten, representing some of the US's most vulnerable supply chains, with the country dependent on China, Tajikistan and Russia for the majority of its antimony sourcing. As with rare earths, the investment focus will shift toward processing capacity for these minerals, since extraction alone does not create supply chain security, with federal attention focusing on processing technologies that break from century-old methods like traditional smelting and refining.

In February 2026, senior officials of the Philippines and the US met in Manila for the 12th Philippines United States Bilateral Strategic Dialogue where they agreed to catalyse private sector development with a focus on the areas of transport, logistics, energy and semiconductors, with the inclusion of mineral processing infrastructure within this broader economic partnership indicating long-term commitment to developing the Philippines' mining and processing capabilities as an alternative to Chinese facilities.

Allied Coordination Framework

This represents genuine multilateralism in industrial terms, recognizing that allied industries may have competitive advantages in specific systems and that distributed production enhances resilience, if Finnish industry produces artillery ammunition, Korean yards build surface combatants, Israeli firms develop counter-UAS systems, and European manufacturers provide precision components, while the United States focuses on advanced fighters, submarines, strategic bombers, and space systems, the collective industrial base becomes far more resilient and productive.

Analytical Integrity Note

Key Uncertainties Acknowledged:

• China's willingness to escalate tungsten export controls versus maintain current licensing regime remains unclear
• Timeline for non-Chinese processing capacity (3-5 years minimum) may compress with sufficient capital, but execution risk is substantial
• Substitution possibilities for defense applications remain limited; no viable alternatives exist for armor-piercing munitions or advanced semiconductor fabrication

Alternative Perspectives Considered:

• Market-driven solution: High prices will incentivize new supply, but 5-15 year development timelines exceed current defense procurement urgency
• Chinese restraint scenario: Beijing may moderate controls to avoid Western retaliation, but recent targeting of Japan suggests willingness to accept diplomatic costs

Evidence Quality Limitations:

• Long-term supply projections (2028+) rely on analyst forecasts, not confirmed production commitments
• Allied mitigation initiatives are policy commitments, not yet operational capacity
• Strategic stockpiling effectiveness depends on demand management, which conflicts with accelerating defense budgets
