Japan's yen depreciated against 11 of its 16 most-traded counterparts as rising stocks in Asia and Europe sapped demand for the safest assets. The euro weakened, snapping a four-day advance, after the collapse of the Irish coalition government threw budget plans into disarray. The pound fell before a report that economists said will show U.K. growth slowed, according to BusinessWeek.
Over the weekend, the Green Party said that it will leave the Republic of Ireland's governing coalition, which will cost the ruling party its majority and mean it's unlikely to survive this week's confidence vote.
