SINGAPORE, May 16 (Reuters) - Shanghai aluminium futures prices on Thursday hit their highest since October 2018 on worries over supply shortage, following a refinery shutdown in China - the world's top aluminium maker.
Xinfa Group, one of China's biggest aluminium smelters, is closing all production lines on its 2.8-million-tonne-per-year alumina refinery in Shanxi for an unidentified period, amid an environmental dispute, causing alumina prices to spike. SMM-ALM-NCHN
The most active aluminium contract on the Shanghai Futures Exchange rose as much as 0.5% to 14,395 yuan ($2,092.69) a tonne in early Asian trading hours. It ended up 0.4%, marking the fifth straight session of gains.
Alumina is a substance used to make aluminium.
"Alumina price has increased a lot this week and likely to remain high, which gives support to the aluminium price. Mid-term demand will still be a key factor worth-monitoring," said analyst Jackie Wang of metals consultants CRU based in China.
While all Shanghai metals rose following an overnight rally in London, sentiment on the London Metal Exchange was cautious for most metals after China released weaker-than-expected retail sales and industrial output data for April.
The figures for April largely pointed to a loss of momentum, after surprisingly upbeat March readings had raised hopes the economy was slowly getting back onto a firmer footing and would require less policy support.
An expected U.S. decision to delay imposing tariffs on imported cars and parts helped sentiment.
