METALS-London copper jumps to highest in over two years as output falls

(Updates prices)

Aug 19 (Reuters) - Copper prices rose on Wednesday as falling Chinese output and a weaker U.S. dollar pushed the London contract to its highest in more than two years.

Three-month copper on the London Metal Exchange jumped as much as 1.8% to $6,686 a tonne, its highest since June 2018. The contract was up 0.9% at $6,628.50 a tonne by 0706 GMT.

The most-traded September copper contract on the Shanghai Futures Exchange closed up 2.2% at 52,150 yuan ($7,536.34) a tonne.

China’s refined copper output in July fell 5.3% from the previous month to 814,000 tonnes, official data showed.

The U.S. dollar, meanwhile, hovered around a 27-month low on uncertainties about an economic recovery and the U.S. fiscal stimulus package.

A weaker U.S. dollar makes LME metals priced in the greenback cheaper for holders of other currencies.

“The Chinese are back buying copper and we might see more Western buyers later as Chinese production fell in July and at the same time Rio Tinto cut full-year guidance due to smelter delays at Kennecott,” said commodities broker Anna Stablum of Marex Spectron.

“Tight supply will hopefully be met by rising demand as Europe and the U.S. will soon come out of the summer doldrums and start consuming again,” she said, adding that the dollar was likely to stay under pressure with minutes from the latest U.S. Federal Reserve meeting due later on Wednesday.
