Russia's central bank has sought to reassure investors by detailing plans to aggressively add to its reserve holdings in a bid to shore up its financial stability.

In a wide-ranging speech at a banking conference on Thursday, Elvira Nabiullina, head of the Central Bank of Russia (CBR), discussed loading up on foreign exchange and gold stocks over the next few years, according to Dow Jones. The central bank plans to push its reserve levels from just over $300 billion to $500 billion, the news agency said.
