LONDON: Copper prices fell on Thursday as worries about growth and demand were reinforced by the second wave of COVID-19 and lockdowns in Europe and as the market awaited the result of next week's US presidential election.
Benchmark copper on the London Metal Exchange was down 0.2% at $6,731 a tonne at 1003 GMT. Prices of the metal used widely in the power and construction industries are down nearly 5% since hitting 28-month highs last week.
"There has been an astounding deterioration in the coronavirus situation pretty much around the world, with the Far East being a notable exception," said ED&F Man Capital Markets' analyst Edward Meir.
Opinion polls on the US election show President Donald Trump's rival Joe Biden with a significant edge nationally, but his lead is tighter in battleground states.
"If Trump wins, metals could sell off because things will stay tense with China," Meir said. "Industrial metals will rally if Biden wins, he will be more conciliatory on all fronts. The dollar could weaken."
DOLLAR: A falling US currency makes dollar-priced commodities cheaper for holders of other currencies, which could boost demand and prices.
TECHNICALS: Copper is struggling to hold above support at $6,725-$6,730, where the 21-day moving average currently sits. A break below will see support at $6,690 the 50-day average.
