Aluminium prices saw a revival during June-August 2009 due to supply concerns of Japanese primary aluminium buyers in the March 2009 quarter. Also, following an accident at Russia’s largest hydroelectric power station in Siberia, RUSAL, the world’s largest aluminium producer, has announced production cuts of about 500,000 tonnes. Between mid-May and 2 September 2009, aluminium prices surged by almost 33% on the London Metal Exchange (LME). However, the record LME inventories of 4.4 million tonnes remain a drag on the metal prices. Moreover, China’s aluminium imports in July 2009 were down almost 51%.
