“The Russian rouble firmed past 64 per dollar on Monday, briefly jumping to 62.71 to the greenback, and climbed towards its highest in nearly five years against the euro, supported by continuing restrictions on currency trading.
The rouble is the world’s best-performing currency so far this year, although this is due to artificial support from capital controls that Russia imposed to shield its financial sector in late February after it sent tens of thousands of troops into Ukraine.”
