By 1248 GMT, the rouble was 5.3% weaker against the dollar at 68.02 , its weakest mark since May 11.
The currency also lost 4.2% to trade at 72.00 against the euro , its weakest since May 6.
Relatively low oil prices and risks of lower export revenue in the light of the $60-a-barrel price cap on Russian oil imposed by the G7, the European Union and Australia, have pressured the rouble.
The dollar-denominated RTS index (.IRTS) was down 5.4% to 982.8 points, a more than two-month low.
