On January 21, the ruble was trading at 84.81 to the US dollar and 92.55 to the euro. However, the next day the Russian currency managed to rebound, trading at 80.26 and 86.86 to the US dollar and the euro, respectively.

Last week, Russian Economic Development Minister Alexei Ulyukayev predicted that the average currency rate would stabilize at 63 rubles to the dollar later this year.
