If you listened to commodities analysts over the past few years, the story on copper was simple: electrification would drive insatiable demand, supply couldn't keep pace with the energy transition, and prices had nowhere to go but up. Copper was the "green energy metal," essential for EVs, solar panels, and grid infrastructure.
So why are global copper inventories now at 23-year highs?
Combined stockpiles across major exchanges—the Shanghai Futures Exchange, London Metal Exchange, and COMEX—have climbed to 1.02 million tons, the highest level since 2002. That's not a typo. Inventories have doubled since September and surged 380% since 2024, marking one of the fastest buildups on record.
London Metal Exchange warehouses alone have posted 27 consecutive days of inventory gains, the longest streak since 2019. COMEX holdings hit a record 534,405 tons in early February. This isn't a minor wobble in supply-demand balance. This is a glut.
What happened? The thesis didn't account for two key realities. First, demand isn't as strong as projected. China's property sector—historically the biggest consumer of copper—remains in structural decline. EV adoption is growing but not at the exponential rates bulls assumed. And the broader global economy is softer than the 2022-2023 narrative suggested.
Second, supply responded faster than expected. Miners brought new capacity online. Recycling increased as prices rose. And some of the feared supply disruptions—strikes, permitting delays, political instability—didn't materialize as severely as forecasts assumed.
Now, does this mean the long-term energy transition thesis is wrong? Not necessarily. Copper is still essential for electrification. The world still needs massive infrastructure investment. But the timeline matters a lot if you're an investor.
Let's be clear about what a 23-year high in inventories signals: supply exceeds demand right now. Not in 2030. Not in some hypothetical green energy future. Today. When you have that much metal sitting in warehouses, prices don't rally. They grind lower until either supply cuts or demand recovers enough to work through the surplus.
