The market for tungsten, a critical metal used in everything from military hardware to semiconductor chips, is currently facing a historic price squeeze. Prices for Ammonium Paratungstate (APT), the key traded form of tungsten, have exploded from around $400 per metric ton unit (mtu) in early 2025 to over $1,800 in March 2026, a staggering increase of over 300% in just over a year.
This unprecedented surge is the result of a perfect storm where multiple powerful forces have collided. The causal chain reveals three distinct layers to this crisis.
First, the most immediate catalyst has been a sharp spike in military demand. Since late February 2026, joint U.S.-Israel military operations against Iran have led to a rapid consumption of advanced munitions. Many of these weapons, particularly armor-penetrating projectiles, rely heavily on tungsten for its density and durability. This has triggered urgent procurement and stockpiling efforts from defense agencies, putting immense pressure on an already tight spot market.
Second, running parallel to the military demand is a strong, structural pull from the semiconductor industry. The boom in AI and high-performance computing has led to massive investments by chipmakers like TSMC, which plans to spend over $50 billion in 2026 alone. Manufacturing these advanced chips requires a specialized gas called tungsten hexafluoride (WF6) to create the microscopic wiring inside. This creates a steady, high-volume demand that forms a solid base for the price rally.
However, neither of these demand shocks would have had such a dramatic effect without the foundational issue: a severe supply constriction. In early 2025, China, which dominates global tungsten production, imposed strict export controls on APT and other tungsten products. This move effectively choked off the primary source of global supply, leaving international markets vulnerable. When the twin demand waves from defense and semiconductors hit, there simply wasn't enough non-Chinese supply to meet them, leading to the parabolic price increase we see today.
- Ammonium Paratungstate (APT): The most important intermediate raw material in the tungsten industry. It is a white crystalline powder that is traded globally and then processed into tungsten metal, powders, and carbides.
- mtu (metric ton unit): A standard pricing unit for tungsten concentrate, equivalent to 10 kilograms of tungsten trioxide (WO3) contained within one metric ton of material.
- WF6 (Tungsten Hexafluoride): An inorganic gas used in the semiconductor industry for a process called chemical vapor deposition, which creates thin layers of tungsten to act as electrical interconnects on a silicon wafer.
