KONTAN.CO.ID - LONDON. London copper prices tumbled on Wednesday to their lowest level since March 2021, dragged down by a robust U.S. dollar and weaker financial markets as fears over a global economic slowdown dented investor sentiment. 

Three-month copper on the London Metal Exchange slipped 3% to $8,725.50 a tonne by 0718 GMT, after falling to its lowest since March 5, 2021 at $8,691. 

The most-traded July copper contract in Shanghai ended daytime trading 1.6% lower to 67,060 yuan ($9,971.60) a tonne. 

Caught in copper's slipstream, LME aluminium fell 2% to $2,483.50 a tonne, zinc slipped 1.3% to $3,544, lead dipped 1% to $2,044.50, nickel lost 3.6% to $25,020, and tin dropped 3.8% to $30,140.

"Base metals remain pressured by a challenging demand outlook related to China COVID-19 lockdowns and to monetary policy tightening raising recession fears over the trade-off between inflation and growth," Standard Chartered wrote in a note. 

"We expect the base metals complex to continue to take its cues from macro developments, USD moves, external market moves and risk appetite trends." 

Asian stocks slipped in volatile trade, failing to extend Wall Street's rally as persistent worries about interest rates and inflation remained a key focus for investors. 

The dollar index jumped 0.5% against its rivals, making greenback-priced commodities more expensive for buyers using other currencies.
