A slide in U.S. bond yields pressured the dollar against the yen on Monday, while the euro struggled for traction after suffering significant losses at the end of last week on renewed concerns about the upcoming French elections.

Markets, already nervous over the possibility of a win for far-right, anti-European Union candidate Marine Le Pen, were jolted after two French hard-left candidates late on Friday said they were discussing cooperation in their bid for the country's presidency.
