The Russian Central Bank was restraining a rise in the dollar exchange rate above the level of 30.59 rubles at today's unified trade, the first in 2002, a banking specialist reported in an interview with RBC. As a result, even the maximum deal was reached not higher than this level. Specialists are sure that the exchange rate of 30.59 rubles per dollar will be the average-weighted level by the end of the trade. In other words, the rate of the national currency will drop by 0.45 rubles. On the first trade last year, which was held on January 4, 2001, the exchange rate dropped 0.32 rubles. The banking expert stressed a significant volume of trade observed on the market and linked this fact to active purchases and sales of dollars by some commercial banks. He noted there were traders who sold large amounts of dollars except for the Central Bank today.
