The dollar exchange rate reached a level of more than 30.5 rubles on the Russian interbank currency market in the morning today, an official from a large Moscow bank announced in an interview with RBC. He specified that dollar transactions were made at 30.51-30.52 rubles for today and they were even higher for tomorrow, which is much higher than the official exchange rate of 30.14 rubles per dollar set by the Central Bank for January 9. This situation denotes that an upsurge in the dollar rate is possible at trading on January 9. The expert stressed that banks have no problems with ruble liquidity right now as one-day ruble credit rates made up about 8 to 13% on average and these rates are forecasted to fall later today. The banking specialist also reported that the presence of the Central Bank was not observed on the interbank market so far.
