Copper retreated in London on Friday and was on track for its fifth straight weekly loss, as worries about COVID-19 curbs in China outweighed hopes for stimulus for the top metals consumer.

Three-month copper on the London Metal Exchange fell 0.5% to $7,780 a tonne by 0428 GMT.

On the Shanghai Futures Exchange, the most-traded August copper contract ended morning trade 1.2% higher at 58,940 yuan ($8,787.83) a tonne, off a session high of 60,540 yuan.

Copper rose sharply on Thursday following a Bloomberg News report saying China was considering allowing local governments to sell $220 billion of special bonds in the second half of this year to boost infrastructure funding.

“While Chinese policymakers are considering boosting stimulus, the headwind from COVID-19 restrictions remain given China is still running a zero-COVID policy,” said National Australia Bank economist Tapas Strickland.

COVID-19 curbs are likely to slow the pace of infrastructure projects, analysts said.

LME copper was so far down more than 3% this week as heightened concerns over a global recession dampening metals demand weighed on markets.
