  • Sberbank CEO Herman Gref said the Russian currency should be trading at 80 to 85 rubles to the US dollar.
  • The ruble is now trading around 96.5 to the dollar. The currency has fallen nearly 30% so far this year.
  • But on Tuesday, Russian President Putin tried to project an image of economic calm.

The boss of Russia's largest bank is unconvinced that the ruble is in a comfortable position — even though Russian President Putin has downplayed the currency's weakness.
