Copper hits record on supply crunch, but demand and policy risks cap rally
US tariffs and stockpiling US tariffs of 50% on copper imports created a premium and encouraged stockpiling, tightening available supply and pushing prices higher.
This is a new policy factor that significantly boosted copper prices in Q3.
Mine disruptions and low inventories Major mine disruptions—Grasberg delays, Codelco's 28-year low, DRC export ban, and Escondida's fatal accident—drained inventories to multi-year lows, intensifying the supply crunch.
These new supply shocks were key drivers of the price surge in Q3.
Demand slowdown and policy risks China's GDP slowed to 4.3% and manufacturing contracted, capping the rally; US tariff doubts triggered a 5% plunge, and hotter inflation revived Fed rate-hike fears, strengthening the dollar and threatening pullbacks.
These new risks acted as a counterweight, preventing further price gains and causing volatility.
