The euro was a tad lower against the dollar and yen in Asian trade Friday, after losing ground in the wake of the European Central Bank's decision to go ahead with its massive asset purchasing program.

ECB President Mario Draghi said the central bank would buy EUR60 billion ($69 billion) of public and private-sector debt every month until at least September 2016, or even later if needed. The move is aimed at supporting growth and lifting inflation expectations in the eurozone.

Around 0450 GMT, the euro was at $1.1345, compared with $1.1361 late Thursday in New York. The common currency hit as low as $1.1316 overnight before stabilizing to the latest level. The single currency also was at Y134.51 from Y134.65.

Investors were "not fully responding during Tokyo time" to the ECB's policy move to adopt quantitative easing given the proximity of the Greek election on Sunday, said a senior Japanese bank dealer.

But the dealer said the ECB's robust stance over monetary easing will likely set to the euro to give it the status of the weakest major currency in the world, adding that a fall in the euro to as far as the $1.100 range is very likely.

"To be honest, I was expecting a market reaction of something like sell the fact" in the forms of the forms of higher yields, stock weakness and the euro's rebound, said Osamu Takashima, chief FX strategist at Citigroup Global Markets Japan, Mr. Takashima in a morning note. But the market is accepting the upside surprise from the ECB's action with no protests in what may suggest "the financial market's stronger-than-expected recovery toward risk appetite," he said.

Elsewhere in Asia, stock markets showed a warm reception to the ECB's massive easing program. The Nikkei Stock Average rose 1.0% midday, while the Shanghai Stock Exchange Composite Index was last up 1.4%.

Shinji Kureda, head of FX trading group at Sumitomo Mitsui Banking Corp. said the monetary easing mood across the globe is a boon to riskier assets such as stocks that may help benefit the dollar-yen trading pair the most.

The dollar was at Y118.58, almost unchanged from Y118.56 in late Thursday trade in New York.

Soon after the ECB steps overnight, Denmark cut its main interest rate on Thursday for the second time this week as it sought to damp interest in its currency among investors selling the euro. Earlier this week, Canada dropped its benchmark overnight rate Wednesday, citing it as "insurance" against the potential economic toll of plunging prices for oil, a key Canadian export.

The WSJ Dollar Index, a measure of the dollar against a basket of major currencies, was up 0.15% at 85.06.
