The euro slipped against the dollar on Friday after Catalan separatists won a regional election, stoking concerns about the possible break-up of the euro zone's fourth-largest economy.
Spain's government had hoped that the Catalan election would strip pro-independence parties of their control of the regional parliament and end their campaign to force a split. But with 96 percent of ballots counted in a vote to elect Catalonia's regional parliament, separatist parties are seen winning 70 seats out of 135.
The euro fell as much as 0.4 percent to $1.1817 in the Asian trading session, before easing up a touch to trade down around 0.2 percent on the day at $1.1852.
"I very much doubt that these losses will turn out to be sustainable," said Commerzbank currency strategist Ulrich Leuchtmann, in Frankfurt.
