An employee handles 100 euro, 5000 ruble and 50 US dollar notes at the counter of an OAO Sberbank currency exchange in Moscow, Russia, on Wednesday, Feb. 1, 2012. The ruble's strongest start to the year since at least 2004 against the dollar may be threatened after protests against the government this weekend remind investors of political risks, according to Societe Generale SA's Russian unit.
