Citi's latest analysis suggests that while copper's long-term future looks bright, near-term headwinds are likely to cool down its red-hot prices.
The main story revolves around a temporary 10% US import tariff. In February, the White House imposed this surcharge, which immediately made it more expensive to bring copper into the United States. This created a U.S. premium, meaning copper prices became higher inside the U.S. than on the global market. Although a trade court recently ruled the tariff unlawful, it remains in place while the government appeals, keeping this price distortion active for now.
So, what happens when one region pays more for a commodity? The supply follows the money. This tariff triggered what's called an arbitrage opportunity, where traders buy copper on the global market (like the LME in London) and sell it at a profit in the U.S. (on the COMEX exchange). The result has been a massive flow of copper into American warehouses, pushing COMEX inventories to record highs. Seeing large, visible stockpiles often makes the market feel well-supplied, which naturally puts downward pressure on prices.
Adding to this pressure is a shift in the fundamental supply-demand story. Earlier in the year, prices spiked above $14,000 based on fears of an imminent supply shortage. However, the International Copper Study Group (ICSG), a key industry analyst, recently flipped its forecast. It now expects a small surplus in 2026, not the deficit it had previously predicted. This change has taken the wind out of the sails of the most aggressive bull narrative.
In essence, Citi's call for moderation to $12,000 per ton is a story of short-term friction overpowering a long-term trend. The combination of policy-driven inventory buildups in the U.S. and a revised global supply forecast is creating a ceiling on prices, even if the world will still need a lot more copper for the green energy transition down the road.
- U.S. premium: A situation where the price of a commodity is higher in the United States compared to the global benchmark price, often due to tariffs, shipping costs, or regional demand.
- Arbitrage: The practice of buying an asset in one market and simultaneously selling it in another market at a higher price to profit from the temporary difference in cost.
- COMEX/LME: Major commodity exchanges. COMEX (Commodity Exchange Inc.) is based in New York and is the primary market for metals futures in the U.S. The LME (London Metal Exchange) is the world's largest market for industrial metals.
