President Trump has announced a universal 50% tariff on copper imports, citing national security concerns. This decision has already led to a significant drop in US copper prices, especially as the tariff exempts refined metals. As the deadline for the tariff approaches, stockpiles are at a 21-year high, and analysts predict turmoil in the copper market. Mining companies view the tariff with mixed reactions, while countries like Chile are seeking exemptions and adjustments in trade agreements with the US. This move is part of broader trade dynamics impacting global mining and technology sectors.
