MOSCOW--The Bank of Russia said Tuesday it didn't shift the ruble's trading band at the beginning of this week for the first time this month as oil prices recovered slightly from October lows.

The central bank said the ruble's trading stood at 37.30-46.30 rubles against the euro-dollar basket by the end of the main trading session Monday, at the same level as late on Friday.

The central bank keeps the ruble within a floating band and starts selling dollars and euros to cushion the currency's decline whenever the ruble moves to the weak end of the band.

As the ruble came under strong downside pressure in early October, the central bank had to carry out the heaviest interventions since March and has been shifting the band daily this month before Monday.

The central bank also said Tuesday it spent $0.21 billion to prop up the ruble slide on Oct. 17.

The ruble eased 0.1% in early trade to 46.28 versus the euro-dollar basket, sliding toward an all-time low of 46.30 hit late last week.
