London copper edged lower on Friday and was headed for a fifth consecutive weekly loss, as concerns over a higher interest rate environment slowing global economic growth dampened investor appetite and boosted the dollar.

Benchmark three-month copper on the London Metal Exchange (LME) was down 0.3% at $9,458.50 a tonne, as of 0718 GMT. The contract is down nearly 3.2% so far this week.

The most-active June copper contract on the Shanghai Futures Exchange ended daytime trading down 1.4% at 72,050 yuan ($10,787.06).

"A stronger dollar weighed on investor appetite," commodity strategists at ANZ said in a note.

"Attention remains on China, where officials are struggling to contain a wave of COVID-19 by increasing restrictions in Shanghai and Beijing. This comes amid tighter monetary policy from central banks around the world."

The dollar firmed near a 20-year high and was headed for a fifth winning week ahead of a closely watched U.S. jobs report, making greenback-denominated metals more expensive for buyers using other currencies.

Asian shares tumbled in a reversal of a day earlier as investors expressed concerns that rising interest rates could lead to a global economic slowdown.
