Nov 5 (Reuters) - Copper prices in London edged lower on Thursday in thin trade, as volatility sparked by the U.S. presidential election tapered off, with Democrat Joe Biden predicting victory over President Donald Trump after winning two critical U.S. states.
A softer U.S. dollar offered some support after slipping to its weakest level in more than two years against the yuan, making greenback-priced metals cheaper for holders of other currencies.
“Now the election buzz is more or less over. Prices are not down too much so far. I think prices were a bit overdone. Market was too optimistic,” said a Singapore-based metal trader.
Biden stopped short of declaring victory, but launched a website for a transition to a Democratic-controlled White House, while Trump alleged fraud, filed lawsuits and demanded recounts in a race yet to be decided a day after polls closed.
Three-month copper on the London Metal Exchange dipped 0.3% to $6,814.50 a tonne at 0715 GMT, having climbed some 56% since its 2020 trough in March, helped by strong Chinese demand, supply disruptions, stimulus hopes and a weaker dollar.
Meanwhile, the most-traded December copper contract on the Shanghai Futures Exchange closed down 0.5% to 51,420 yuan a tonne.
* LME aluminium fell 0.5% to $1,898 a tonne and zinc declined 0.3% to $2,586 a tonne, while lead was down 0.3% to $1,836.50 a tonne.
