At 0715 GMT, the rouble had eased 0.2 percent to 62.42 against the dollar and lost 0.1 percent to trade at 68.45 versus the euro.
The rouble's depreciation follows a 0.74 percent decline in Brent crude prices to $52.28 per barrel. But domestically the rouble is supported by a monthly tax period that usually prompts export-focused companies to convert their dollar revenues to meet tax duties.
The stock market lacks reasons for growth so the Micex index may dip lower, while the rouble still has room to firm, Otkritie brokerage said in a research note.
The rouble-traded Micex index was 0.15 percent lower at 1964.44, while the dollar-denominated RTS index was down 0.39 percent at 991.35 points.
