The euro hit fresh lows against the dollar and the yen before staging a rebound later in the session in choppy Asian trade Monday, with the common currency coming under selling pressure due to uncertainties in the eurozone after Sunday's Greek elections.

Around 0450 GMT, the euro was at $1.1174, compared with $1.1208 late Friday in New York. The single currency touched as low as $1.1098 -- its weakest level since Sept. 9, 2003 before stabilizing to the latest level.

The euro also was at Y131.41 from Y132.08. That was higher than its low of Y130.16 earlier the day, the lowest since Sept. 6, 2013.

Greek radical leftist party Syriza is set to win Sunday's election with a government projection giving the antiausterity party 150 seats in Greece's 300-seat parliament with the backing of 36.3% of voters in a fraught and historic national election that could determine the country's future in the eurozone and reverberate across Europe.

The initial currency market reaction was negative, with investors selling the euro on uncertainties over the eurozone situation. But having experienced massive selling and short positions building up after the European Central Bank's decision Thursday to go ahead with its massive asset purchasing program, the euro was less immune to covering of investors' short-positions.

As the Greek vote count proceeds, the euro has been bought back with short covering kicking in.

"We see volatile movements over the short term. It would not be a surprise if the euro reaches $1.13," said Kenji Yoshii, FX strategist at Mizuho Securities.

But Mr. Yoshii said the euro is vulnerable to fall back again and test further downside as political developments unfold.

The result of the elections is expected to have lasting repercussions for both Greece and the eurozone. Syriza, which emerged as the main opposition party in mid-2012 at the depths of the nation's debt crisis, has promised to tear up the austerity program that Athens pledged in exchange for a EUR240 billion ($269 billion) bailout from international creditors.

"There will be no change that the euro remains top heavy," on concerns about the Greek situation and given the ECB's massive asset purchasing program, said FPG Securities chief executive Koji Fukaya, adding that the euro could fall $1.10 over the short-term.

Among other currency pairs, the dollar was at Y117.57 from Y117.81 late Friday in New York, ahead of the closely-monitored Federal Open Market Committee Tuesday and Wednesday.

The greenback also recouped its earlier losses, as jitters over the Greek election diminished with the euro bouncing back from fresh lows earlier in the morning.

The WSJ Dollar Index, a measure of the dollar against a basket of major currencies, was up 0.16% at 85.54.
