Copper prices tumbled to a near 17-month low on Friday and were set for their fourth consecutive weekly decline, as fast-rising interest rates and weak economic data stoked fears of a global recession, which would dent demand for metals.
Other industrial metals also fell, with zinc dropping over 6% this week and aluminium heading for its sixth straight weekly fall, down 2.4%.

"This suggests the market views the improvement is not enough to offset the potential slowdown in developed economies."
