TOKYO, Sept 25 (Reuters) - The euro slipped on Monday after German Chancellor Angela Merkel won a fourth term in a weekend election, but faced leading a much less stable coalition in a fractured parliament as support for the far-right party surged.
"The market reacted by selling the euro on the possibility of Merkel running into difficulties in forging a coalition. The euro, however, was already losing support from the European Central Bank's monetary policy theme and appeared to be on its way lower," said Daisuke Karakama, chief market economist at Mizuho Bank in Tokyo.
"The election outcome in Germany showed the country was no longer a special presence in Europe amid growing support for populism and the far right."
The euro was down 0.2 percent at $1.1934, putting more distance between a 2-1/2-year high of $1.2092 reached on Sept. 8, when a European Central Bank policy meeting left currency bulls optimistic the ECB would begin tapering its big stimulus program.
The New Zealand dollar suffered a similar setback, falling as New Zealand's ruling National Party won the largest number votes in Saturday's election but without a ruling majority and now faces a round of coalition building that could last days or weeks.
The New Zealand dollar, the world 11th most-traded currency, was down 0.7 percent at $0.7288.
