(Updates prices, adds details and quotes) June 23 (Reuters) - Copper prices rose on Wednesday as testimony from U.S. Federal Reserve chair Jerome Powell eased worries of a sooner-than-expected rate hike that could dampen liquidity into metals. Three-month copper on the London Metal Exchange was up 0.5% at $9,344.50 a tonne, as of 0701 GMT, while the most-traded July copper contract on the Shanghai Futures Exchange closed 2% higher at 68,480 yuan ($10,562.36) a tonne. Powell on Tuesday reaffirmed the central bank’s intent to encourage a “broad and inclusive” recovery of the job market, and not to raise interest rates too quickly based only on the fear of coming inflation. “Fed’s Jerome Powell played a clever balancing act to try and calm nerves over inflation and pushing back the potential for sooner-than-expected interest rate rises,” Malcolm Freeman, a director at UK brokerage Kingdom Futures said. Last week, investors fretted that the U.S. central bank could tighten its policy soon, leading to LME copper dropping 8.6%, its biggest weekly fall since March 2020.
