LONDON, Aug 12 (Reuters) - Lead prices touched a two-week high on Monday after Belgium-listed Nyrstar said it had stopped production at its Port Pirie smelter in Australia, raising fears of shortages of the metal mainly used in car batteries.
The stoppage is the second this year at the lead smelter and follows an outage in June and July, when 30,000 tonnes of metal were lost in the 12 million tonne market.
Benchmark lead on the London Metal Exchange (LME) touched its highest since July 26, at $2,101.50 per tonne, but closed 0.2% lower at $2,065.
"There is uncertainty on when the smelter will be back up and running on a reliable basis and this should support prices," said Capital Economics Senior Commodities Economist Ross Strachan.
"But it's still fairly gloomy on the economic background with the trade war," Strachan said, adding this could cap gains in base metals.
MARKET BALANCE: During the first five months of the year, the global lead deficit increased to 42,000 tonnes from 34,000 tonnes in the same period last year, according to the International Lead and Zinc Study Group.
INVENTORIES: Inventories of lead at LME-approved warehouses fell 800 tonnes to 82,475 tonnes, having jumped about 50% since hitting their lowest since 2009 three weeks ago. MPBSTX-TOTAL
SPREADS: Low inventories have created a premium for cash nickel to the three-month contract, which by Friday stood at around $14 a tonne, although this was down from nearly $30 on Thursday CMPB0-3.
POSITIONS: Shortage concerns are exacerbated by one entity holding between 50% and 79% of LME warrants <0#LME-WHL>.
GLOBAL GROWTH: The economic outlook has deteriorated in all parts of the world over the summer due to an escalating trade dispute between the United States and China, a survey showed on Monday.
TRADE WAR: On Friday, U.S. President Donald Trump said he was not ready to make a deal with China and even called a September round of trade talks into question.
CHINA CARS: Sales of new energy vehicles in China fell 4.7% in July from a year earlier, the first drop in more that two years, data from the country's biggest auto industry association showed.
NICKEL: Nickel finished 1% higher at $15,710 a tonne, after hitting a 16-month high of $16,690 last week on the possibility of Indonesia bringing forward a ban on mineral ore exports.
Indonesia aims to speed up enforcement of a ban on mineral ore exports due to come into force in 2020, news website Detik.com quoted coordinating minister for maritime affairs Luhut Pandjaitan as saying.
PRICES: Copper closed 0.2% lower at $5,742 per tonne, while aluminium was unchanged at $1,771. Zinc gained 2% to $2,278 after touching a three-year low, while tin closed down 0.4% at $16,825, after also touching a three-year intraday low.
