Copper Supply Squeeze Intensifies as Exchange Inventories Dwindle

Copper faces a supply squeeze as only 33% of inventories are freely available. Surging demand from AI and electrification meets a structural deficit, risking price volatility.

A significant supply constraint is building in the copper market, even as prices have recently softened. A critical shift in global stockpiles is underway, with only one-third of above-ground inventories now freely available on exchanges. The remaining majority is locked away in state and industrial strategic reserves, setting the stage for potential price volatility in the coming months.

Industrial Demand and Production Deficits

Robust industrial consumption continues to underpin the market. The global push for electrification and the expansion of power grids, coupled with the substantial power needs of artificial intelligence data centers, are fundamental drivers. These forces propelled the copper price above $6 per pound in February. Although it settled at $5.77 on Tuesday, the core structural issue remains: mine supply is struggling to keep pace with the rapid demand from technology and infrastructure sectors.

This persistent global supply deficit is forcing the market to rely increasingly on visible exchange inventories, elevating the risk of sudden delivery shortfalls.

A Dramatic Shift in Visible Stocks

The composition of global copper stockpiles has undergone a risky transformation. Market analysts, including Daniel Ghali of TD Securities, highlight that inventories registered on exchanges now represent approximately 33% of total above-ground stocks. This marks a stark increase from just 5% at the end of 2023.

This data reveals that 67% of inventories are effectively inaccessible. These include the strategic reserves held by nations like China and the United States, as well as operational minimum stocks required by industry. The drawdown on exchange warehouses is becoming a key indicator for investors to watch.

Exploration Races to Bridge the Gap

In response to the looming supply gap, exploration companies are accelerating investments into new projects. Recent developments include:
- Star Copper Corp.: The company confirmed an extension of mineralization at its "Star" project in British Columbia.
- Drill Results: One intercept reported 80.30 meters grading 0.508% copper equivalent.
- Investment Plans: An exploration budget of $10 million USD is planned for 2026.

Over the next several months, the trajectory of visible inventories will be decisive. If the global deficit continues to drain exchange reserves, market volatility is likely to increase, potentially driving prices back toward the 52-week high of $6.28.
