The dollar exchange rate went up at the morning trading session today, which happened for the first time over the past two weeks. Currency analysts believe that one of the reasons for a new weakening of the national currency was a noticeable drop in the dollar rate yesterday, when the US currency rate plummeted RUR 0.09, the most significant decline in the dollar rate over more than a year. Earlier, top officials at the Russian Central Bank announced more than once that they would not allow sharp fluctuations on the domestic currency market and would take measures to secure a quiet situation. It seems that today the Central Bank decided to compensate for yesterday's drop in the dollar. Bank experts who spoke to an RBC correspondent are sure that in the future the Central Bank will not allow a rise or a fall in the dollar rate by more than RUR 0.05 per day.
