Copper prices bounced on Wednesday as worries diminished that the Omicron coronavirus variant would hit demand for industrial metals.
Three-month copper on the London Metal Exchange was up 1% to $9,535 a tonne by 1125 GMT, having lost 0.6% in November.
A green transformation to electric vehicles and wind turbines plus new infrastructure projects will require more copper even if a spreading pandemic spurs tighter restrictions, said Ole Hansen, head of commodity strategy at Saxo Bank in Copenhagen.
"These projects are not going to go away even though we see a dip in growth again or a period of lower mobility," he said.
"Adding to that, inventory levels are still very low and it does seem like copper is being consumed and leaving these major exchange warehouses, which is another layer of support."
Metals benefited from investors' increased risk appetite, which sent stock markets surging, using a dip in prices to bet the latest COVID-19 variant would not derail the economic recovery, while oil also rallied.
