LONDON, Aug 8 (Reuters) - Copper hit its highest in almost two months on Thursday as upbeat trade data and better-than-expected imports of the metal in top consumer China reinforced hopes of a revival in demand for industrial materials.
A broad-based move, also bolstered by a weak dollar, saw many short position holders buying back positions, sweeping other industrial metals higher. Lead also touched the highest levels in nearly two months while tin surged to a near-four-month peak.
Surprisingly firm rebound in China’s exports and imports in July offered some hope that the world’s second-largest economy might be stabilising after more than two years of slowing growth.
Three-month copper on the London Metal Exchange surged 2.6 percent to close at $7,185 a tonne after touching a session peak of $7,215, its strongest since June 11.
“The data supports our positive view that the period of destocking in China is over and we forecast an improvement in metals demand and also a stabilisation of growth in China over the coming months,” said Eugen Weinberg, analyst at Commerzbank.
“Sentiment was also very downbeat in the market and the data has triggered some short-covering.”
China is the world’s largest copper consumer, accounting for around 40 percent of global refined demand.
Data showed China’s imports of copper rose 8.1 percent to 410,680 tonnes in July from 379,951 tonnes in the previous month.
Some analysts said although the figures from China were positive, a seasonally slower month for demand could prevent sustained gains for the metal in the short term.
“Markets are near record shorts in copper so after positive news in China’s trade data, we could see copper prices finally break out from the recent trading range, but I don’t think it will be sustained,” Natalie Rampono at ANZ in Melbourne said.
“We’re in the seasonally slower months for demand, so we’re still expecting a bit of near-term weakness,” she said, adding markets may well be preempting the expected seasonal fourth-quarter recovery in demand.
Markets appeared to welcome U.S. data, which showed that although the number of Americans filing new claims for jobless benefits rose slightly last week, it was still near its lowest level since before the 2007-09 recession.
Also supporting gains in metals was the dollar, which slumped to a seven-week low against a basket of currencies as recent inconclusive economic data and comments from Federal Reserve policymakers raised doubts over when the U.S. central bank will begin reducing stimulus.
A weak dollar makes commodities priced in the U.S. unit cheaper for holders of other currencies.
In industry news, mining group Rio Tinto has scrapped efforts to sell its loss-making Pacific Aluminium business, blaming poor market conditions as weaker iron ore, copper and coal prices dragged first-half profit down 18 percent.
Rio also said that it will shut down its aluminium smelter in Shawinigan, Quebec, by the end of November.
“Indeed, the sustained period of weak aluminium prices and chronic oversupply, particularly in China, has forced producers to cut output with Chinese production curtailments accelerating in June-July,” analyst Wiktor Bielski at VTB Capital said.
“However, most of the cuts in China are designated as temporary cuts, indicating they could resume operations when prices improve,” he added in a note.
Aluminium, zinc and nickel hit the highest levels in two weeks, with aluminium closing 2.4 percent higher at $1,840 a tonne, zinc adding 2.5 percent to $1,895 and nickel climbing 2.5 percent to end at $14,330.
Tin, which has been the strongest performer so far this year among major LME metals, finished 2.1 percent higher at $21,700 a tonne, the highest since April 15.
Lead added 1.6 percent to $2,139 a tonne after hitting a session peak of $2,147, the highest since June 11.
