The most-traded August copper contract on the Shanghai Futures Exchange rose 1.5% to close at 69,670 yuan a tonne for a third straight weekly gain.
Copper, which is used in the power and construction industries among others, is widely viewed as a gauge of global economic health.
“We saw a slight bounce in equity markets yesterday as upbeat earnings helped to overcome worries about growth. Together with a stable dollar, it means metals can trade a bit more on their own fundamentals,” said Marex Spectron commodities broker Anna Stablum.
Sluggish inflation and the European Central Bank’s pledge to keep interest rates at record lows for longer also lent support.
“(This) might add to bullish sentiment. Loose monetary policy is a big reason why we are up here in the first place,” Stablum said.
