The Economics of Copper Demand, Supply and Options
· While the pandemic did little to interrupt demand for copper via manufactured goods and housing, it did disrupt mining supply. Many mines in Chile, which accounts for 28% of global copper supply, closed for at least part of 2020 as a result of COVID19. This led to a % dip in copper production globally during the second quarter of 2020.
