- Russia's central bank chief on Friday said the authorities have all the tools needed to ward off instability as she sought to calm the markets after a rollercoaster week that saw the ruble hit a new low against the dollar. 

"We have all the means to be proactive and prevent threats to financial stability in advance," Elvira Nabiullina was quoted as saying by RIA Novosti news agency at a finance ministry meeting, insisting the bank was "closely following the situation on the market."
