The majority of participants of the exchange market don't count on a significant dollar fall today, even though they expect it to continue sliding down. Experts say, the oil price collapse on world markets last fall led to a decrease in the currency revenues of our country. Thus, it can be stated now that the dollar rate almost hit its "bottom" level. As soon as a break occurs in the dollar fall, and the Central Bank doesn't do anything about that, traders may begin fixing long positions counting upon the dollar increase to the 30.70-ruble level. That's how experts characterized the course of trading on the unified trading system and SELT. On the other hand, operators don't quite understand the dynamics of dollar fluctuations. The situation mostly depends on the Central Bank, which can move the dollar in any direction. As long as world oil prices remain unchanged, our country regularly receives the US currency. In other words, the Central Bank is able to turn to strict policies and restrain the dollar growth. Actively interfering in the trading, the Central Bank hasn't let the dollar surge over the last several days. The bank seems to be trying to balance the market, to make the US currency independent from speculators.
