LONDON, July 16 (Reuters) - Nickel prices surged to theirhighest in 11 months on Tuesday, propelled by buying fromspeculators and industrial consumers worried about potentialfuture shortages.
A key ingredient in batteries for electric vehicles (EVs),nickel could be subject to increasingly heavy demand with anexpected shift from diesel and petrol cars in the coming years.
"We've been hearing about consistent strong Western consumerbuying as the main driver of the price, probably related to EVnickel hedging requirements," said Nicholas Snowdon, metalsanalyst at Deutsche Bank in London.
Current estimates peg the future supply situation as lesscritical than forecasts from a year ago, but industrial buyersremain nervous about availability, Snowden said.
"The balance has softened from a sizeable deficit to closeto balance," he said. "But it's not a sudden swing back tosignificant surplus and ample availability, so I think there'sstill a concern over making sure that you have enough rawmaterials."
As nickel prices ramped up, buying from speculators extendedthe rally, one broker said. "It's CTA (commodity tradingadvisers) momentum buying ... that is pushing things (nickel)higher."
CTA funds often base trading decisions on chart patterns andtechnical levels, including momentum.
