The Russian ruble rebounded slightly as markets opened Wednesday, after the currency lost a fifth of its value in a single day in the worst crisis of President Vladimir Putin's 15 years in power.
At around 0730 GMT, the ruble was trading at 66.96 to the dollar, down from 67.88 on Tuesday evening, and at 83.35 to the euro from 85.15. The central bank said it had spent almost $2 billion in a bid to prop up the currency on Monday.
