The euro bounced amid polls indicating rising support for Greek parties in favour of the country's international financial rescue, fuelling hope a break-up of the single currency can be avoided.
The beleaguered euro rose as much as 0.9 per cent earlier in the session, and was last 0.5 per cent stronger at US$1.2573.
Greece's New Democracy party, which supports the bailout plan, ranked first in all six opinion polls published in recent days.
"Anything that allays fears over Greece is a positive. People are just looking for a bit of respite," Bastion Capital's head of equities Adrian Slack told Reuters.
New Democracy would get between 25.6 per cent and 27.7 per cent of the vote if the election was held today, according to a Reuters report on polls by Eleftheros Typos/Pulse, Proto Thema/Alco, Real News/MRB, To Vima/Kapa and Ethnos/MARC. SYRIZA's support was between 20.1 and 26 per cent.
