The weighted average dollar exchange rate on tomorrow deals amounted to 30.31 RUR/USD at 11:30 Moscow time. So, the official dollar rate for August 21 has eased back by RUR0.02. Commercial bank dealers believe that the ruble's strengthening at the UTS could have been more considerable, if the Russian Central Bank had not hindered the dollar's weakening.
Some experts believe that the Central Bank made a bid for US currency at 30.30 RUR/USD at the special session. So the low on the dollar did not drop below this level in the first 90 minutes of the UTS.
