Aug 19 (Reuters) - London copper prices dropped below $9,000 a tonne to their lowest in more than four months on Thursday on a stronger dollar and easing supply disruptions.
Three-month copper on the London Metal Exchange fell as much as 1.4% to $8,913.30 a tonne, its lowest since April 14, before rebounding to trade at $8,950 a tonne by 0702 GMT, still down 1%.
“The key area for copper on the monthly chart is $8,590 and a move through that level could trigger a 50% Fibonacci correction which would signal a move to $7,450,” said Malcolm Freeman, director at brokerage Kingdom Futures, adding that the U.S. employment numbers due later in the day would offer more cues.
The most-traded September copper contract on the Shanghai Futures Exchange ended down 3.1% at 66,790 yuan ($10,282.03) a tonne, its lowest close since June 22.
The dollar rose to a nine-month high against its major peers on expectations that the U.S. Federal Reserve will start tapering its huge stimulus this year, making greenback-priced metals more expensive to holders of other currencies.
Residents near MMG Ltd’s Las Bambas copper mine in Peru lifted the blockade of a road used to transport the metal, while operations resumed at Teck Resources Ltd’s Highland Valley Copper operations in Canada after a wildfire evacuation order was lifted, easing copper supply pressure.
