What's Driving
Metal Prices

Factors creating the on-going surge in copper prices and base metal prices.

metals@anchorbronze.com

The U.S. imposed a 50% Section 232 tariff on the copper content of semi-finished and derivative copper products, effective August 1, 2025. These tariffs aim to bolster domestic production but create complexities for businesses in pricing, sourcing, and compliance, affecting global copper markets. 

In addition copper costs are soaring due to massive demand from the energy transition (EVs, renewables, grid) and AI data centers colliding with slow mine supply growth, production disruptions (labor, technical issues), aging mines, and government policies like tariffs, creating a structural supply deficit.
