MOSCOW, Dec 4 (Reuters) - The Russian rouble hit three-week lows on Monday, under pressure from weaker global oil prices due to market scepticism over last week's voluntary OPEC+ supply cuts.
At 1629 GMT, the rouble was 0.6% lower at 90.93 to the dollar, having touched 91.18, its weakest since Nov. 14.
It had shed 0.56% to trade at 98.49 versus the euro , having previously fallen to 98.90, its weakest level since Nov. 13.
It was down 0.86% at 12.73 to the yuan, just off a one-month low of 12.76 earlier in the session.
Russian exporters last week completed payment of October taxes, for which they need to convert currency into roubles.
The rouble has also benefited from October's presidential decree on mandatory forex sales by exporters, though some market participants believe the boost from that measure is starting to wane.
Brent crude oil, a global benchmark for Russia's main export, had recovered some of its losses and was down 0.2% at $78.70 a barrel.
Russian stock indexes were also lower, with the dollar-denominated RTS index down 1.67% to 1,077 points and the rouble-based MOEX Russian index 0.89% lower at 3,114 points.
