[LME nickel and aluminum futures rise due to heightened supply concerns] London nickel and aluminum futures rose on Wednesday, amid growing concerns about Russian supply disruptions and low inventories after tightening sanctions on major metal producer Russia. The world's three largest container shipping companies suspended shipments of goods to and from Russia on Tuesday in response to western sanctions against Moscow, dealing a further blow to Russia's international trade. Russia produces about 6 per cent of the world's aluminium, accounting for 7 per cent of the world's nickel supply and is a major producer of natural gas.
