MOSCOW: The Russian currency ruble fell due to weaker oil price and it was 1.5 percent down against the dollar at 53.30, and 1.2 percent down at 65.45 against the euro.
The price for Brent crude was down more than 1 percent at 68.33.
The ruble closed up 3 percent against the dollar. This was linked to Central Bank interventions to support it, traders said, but there was little sign of more interventions so far on Monday.
The Central Bank said that it had not carried out any interventions on Thursday. The bank releases interventions data with a two-day delay. This follows $700 million in interventions last Monday and $1.9 billion.
Russian stock indexes were mixed. The ruble-based MICEX index was up 0.3 percent to 1,534 points, while the dollar-based RTS was down 0.2 percent to 907.
