Fresh waves of turbulence engulfed emerging markets on Friday, with a renewed slide in the Russian rouble and a sharp rise in bond yields across the board despite policymakers' efforts to staunch the bleeding.
Signs grew that stress is increasingly spreading to central European countries such as Poland and Hungary, which fared relatively well in the first sell-off phase earlier this month.
