[LME close on May 15: Metals rose generally, with futures copper rising to a two-year high driven by demand prospects] LME futures copper hit a two-year high on Wednesday, helped by the weakening of the US dollar and bullish demand prospects, while CME copper prices hit a record high. The abnormally large price gap between the two remains a focus of market attention. London futures copper has risen 20% this year so far, still $640 short of the all-time high of $10,845 hit in 2022. The rise in copper prices is due to limited supply of raw materials and market bets that the metal will benefit from additional demand from the green energy industry. (Wenhua Finance)
