“Copper has been, and will continue to be, the fundamental metal of the electrical industry.”
— Sir Walter R. G. Baker, Electrical World magazine, 1920
Copper is one of the first metals used by humans 11,000 years ago. It is the second most conductive metal on the planet and has played a crucial role in history, ranging from early weaponry to coins to electricity. Now, electricity, like copper, is entering an exponential use period as the world’s insatiable demand for power is on a seemingly unstoppable path.
History shows us that when the need for certain assets booms, the desire to control them grows even more. That’s why August 1 will be a key transformational day for copper. That’s when a crucial 50% U.S import duty on copper is set to take effect. And, even if trade agreements surrounding that line in the sand don’t fully transpire, the proposed tariff itself means the stage has been set for more scrutiny over copper supply chains for months and years to come.
The change is important to monitor because the White House trade measure covers cathode, wire rod, and semi-finished copper products. These aspects cover nearly everything that U.S. manufacturers rely on to power factories, build grids and run electric vehicles.
This trade policy represents the realization that copper, both raw and refined, is strategically important to energy and national security. The historic maneuver also creates a tangled, fragmented trade environment that is as much geopolitical as it is economic.
Across the planet, governments, businesses and traders have been scrambling to adjust and understand the broader implications of this action. This rapid movement recently pushed copper to record highs. It has also pressed key multinational copper companies to up their bid for global market share – with one in particular in a prime position to reap the benefits.
While the initial reaction to the White House announcement on July 30, which included copper as well as certain copper products, prompted a sharp decline in prices, we think this is an overreaction. Ultimately, copper is a long-term opportunity – and one we remain optimistic on.
What Triggered the Recent Copper Rush
On July 7, the White House formally announced a 50% copper tariff. In response, COMEX copper futures surged over 13% the next day, hitting an all-time high above $5.65 per pound ($12,330/ton). That was the largest single-day move since 1968.
Copper futures had risen steadily since to a new record of $5.79 per pound. The jump doesn’t just reflect speculative trading. It’s the market pricing in guaranteed delivery and hedging tariff risk. Even in the face of recent news with COMEX, the high demand and data tell us the real story.
Increases in copper inventory data showed a potent copper squeeze. Refined copper imports are surging. COMEX warehouse reserve levels in the U.S. ballooned to nearly 248,000 metric tons in late July. That’s more than double the March levels.
However, this physical inventory bump is misleading as a measure of demand. That’s because mostly, it’s allocated to forward-booked supply and does not represent excess capacity. That means the inventory is locked in by buyers securing supply before the tariff deadline.
At the London Metal Exchange, warehouse inventories have plummeted by about 80% this year.
This divergence between bulk buyers in the U.S. and dropping inventories in the rest of the world paints a dramatic picture. It shows that refined copper is physically moving into tariff-protected U.S. warehouses, which is draining global inventories – and pressuring prices. And that spells upside for miners extracting or producing high-quality raw and refined copper.
We Signaled This Copper Shift Last Year
The U.S. and global copper supply chain participants had been bracing for this moment for months. Last year, we discussed factors driving increasing copper demand and how it would lead to higher copper prices. Since then, the stakes have been driven even higher.
On March 3, the U.S. Commerce Department launched its Section 232 investigation into copper imports. That was the initial sign of official intent to examine the strategic importance of copper as a national defense item.
What you should know is that Section 232 is part of the Cold War era 1962 Trade Expansions Act. The act was designed to determine whether certain materials or products are critical to U.S. national security.
That’s why, the report, released on July 30, from the White House is worth paying attention to. It found that, “copper is being imported into the United States in such quantities and under such circumstances as to threaten to impair the national security of the United States.” Below, is one area of key findings that the government report detailed, noting:
“Copper is the second most widely used material by the Department of Defense and is a necessary input in a range of defense systems, including aircraft, ground vehicles, ships, submarines, missiles, and ammunition. Copper also plays a central role in the broader United States industrial base. The metal’s exceptional electrical conductivity and durability also make it indispensable to critical infrastructure sectors that support the American economy, national security, and public health. Alternatives to copper are insufficient substitutes for these vital industries and products in many circumstances.”
The 232 investigations into copper serve as a key milestone in White House efforts to secure more of the copper supply chain – and why, from raw material to refined products, they are critical.
