The euro weakened against most of its peers, falling to a two-week low against the greenback after inflation slowed more than expected and unemployment in the eurozone rose to a record.
The weak data added to speculation the European Central Bank will lower its key interest rate from a record low 0.5 per cent to underpin economic growth in the region.
Annual inflation slowed to 0.7 per cent in October, the lowest rate since November 2009. The pace was expected to remain unchanged at September's 1.1 per cent rate, according to a Bloomberg survey. The jobless rate climbed to a record 12.2 per cent.
The data "should strengthen the case for more policy easing," Neville Hill, an economist at Credit Suisse Group AG in London, told Bloomberg. ECB president Mario Draghi "may want to leave the door open to the possibility of a rate cut at the December meeting" at his scheduled media conference next week.
The euro fell 1 per cent to $1.3594 and weakened more than 1 per cent to 133.66 yen.
