The euro hit record highs against the dollar for a second day on Christmas Eve, boosted in thin trade by worries about the US current account deficit and economy.
The euro pushed above $1.35 on Thursday after US new home sales tumbled 12% in November, the sharpest decline in more than a decade.
Investors see little likelihood of near-term official action to stop the dollar's slide, with Dutch Finance Minister Gerrit Zalm saying the euro's rise was still within acceptable margins.
The euro traded as high as $1.3546 on Friday morning.
