Aluminium hits 3-month high after Hydro cyber attack

London: Aluminium touched a three-month peak on Tuesday after major producer Norsk Hydro was hit by a cyber attack, causing its giant smelters to switch to manual operation and some extrusion plants to be shut.

Other industrial metals also gained ground on optimism about easy monetary policy ahead of a US central bank meeting and on hopes for further stimulus in top metals consumer China.

Aluminium prices spiked after Hydro said the IT systems for most of its activities had been affected.
