MOSCOW: Russia's central bank has sold $22.3 billion and 2.3 billion euros in forex interventions in March to support the rouble, it said on Wednesday.

The Russian central bank has spent $41.1 billion since the beginning of the year to support the national currency, hit by the US Federal Reserve curtailing its stimulus programme and Russia's annexation of Crimea peninsula.

Since the beginning of the year, the rouble has lost almost 7 percent against the dollar-euro basket.
