LONDON: Copper was set for its eighth consecutive weekly gain on Friday, with prices back to pre-coronavirus crisis levels as Chinese demand rebounds and speculators turn bullish on the metal.

Benchmark copper on the London Metal Exchange (LME) was up 0.4% at $6,324 a tonne at 1116 GMT.

It was up 5% this week after Thursday's rise to $6,360, the highest since May 2019 and up from a low of $4,371 in March.

"Chinese demand seems to be coming back not just quickly but quicker than most people expected," said Capital Economics analyst Kieran Clancy. "There's also starting to be a supply risk priced into the copper price.

"In some countries, particularly in Latin America, which produces half the world's copper ore, restrictions are being lifted at a time when infections are rising," he said.

CHINA: New bank lending in China, the biggest metals consumer, rose 22.3% to 1.81 trillion yuan ($258.29 billion) in June.
