Copper Prices Surge as Copper Flows into US Amid Tariff Uncertainty

Copper prices have reached a six-month high due to shifting supply dynamics. Copper is leaving London Metal Exchange (LME) warehouses and moving to the US, where uncertainty around tariffs has created an arbitrage opportunity.

The available copper in LME-registered warehouses fell by 11,925 tons to 106,950 tons on Tuesday, leading to concerns about a tighter market. BNP Paribas noted that the price gap between the US's COMEX futures exchange and the LME has kept supply flowing into the US delivery system.

This movement of copper can have a significant impact on prices, as shown by the 106,950 tons of LME copper that can move markets faster than expected. The front-end pricing in the LME, which includes cash and nearby contracts, is particularly susceptible to sharp price swings due to competition for immediately deliverable metal.

Hedge funds and other short-term traders have been taking advantage of these inventory headlines, amplifying day-to-day price movements. This situation raises the risk of short-lived squeezes and choppy 'time spreads', making hedges tied to LME pricing less predictable until tariff expectations and inventory flows settle.
