A strong U.S. jobs report gave the dollar a lift Friday, while a report from a German newspaper saying Greece could withdraw from the euro bloc drove that currency lower _ although some analysts were skeptical about how realistic such a scenario was.
The bump up follows a long decline for the dollar, which hit multi-year lows against several currencies earlier this week.
The dollar has fallen because of the Federal Reserve's signals that it will keep rates low for at least the next few months in order to support the economy.
Other central banks around the world are raising rates to counter rising food and energy prices. Higher rates tend to support currencies.
On Friday, however, investors got some evidence of momentum in the U.S. economy after a recent run of weak data. The government said 244,000 jobs were added in April. Private employers added 268,000 jobs, the most since February 2006. But the jobless rate rose to 9 percent from 8.8 percent the previous month as more people looked for work.
"The firming in the labor market has to be a major topic of conversation at the Fed," said Joel Naroff of Naroff Economics in a research note. "More and more it is looking as if the recovery is on track despite the headwinds it is facing, and the FOMC will have to deal with that trend." The FOMC, or the Federal Open Market Committee, is the Fed panel that sets the country's interest-rate policy.
In late trading Friday in New York, the dollar built on recent gains against the euro after the U.S. currency's steep 10 percent decline this year. The euro tumbled to $1.4337 from $1.4530 late Thursday _ a huge drop from its peak of $1.4942 on Wednesday. That was the euro's highest level since December 2009.
Analysts said the main factor weighing on the euro Friday was a report posted on the website of a German newspaper, Der Spiegel, that said the Greek government was considering leaving the euro currency bloc.
Finance ministers from several European countries met Friday amid concerns over Greece and Portugal, as Greek and other European Union officials vehemently denied that Athens was considering leaving the eurozone.
Greek Finance Minister George Papaconstantinou attended the informal meeting in Luxembourg.
"It is absolutely evident that in these talks there was no discussion nor was any issue raised concerning Greece's participation in the eurozone, as various foreign media outlets said irresponsibly and for their own reasons," the Greek Ministry said in a statement.
Steffen Seibert, spokesman for German Chancellor Angela Merkel, said that "there is a meeting of some finance ministers that has long been planned. Greece exiting the eurozone is not on the agenda of that meeting, and it has never been."
Greece was bailed out last year and its economy has struggled amid steep cuts in government spending and other reforms put in place as part of the emergency aid package from its European neighbors and the International Monetary Fund.
Despite dismissals from officials, the story "does seem to be having a market effect," said Ron Leven, currency strategist for Morgan Stanley in New York. But he played down the significance of the report. "For (Greece) to leave the euro is very complicated. It's not like they can just wake up tomorrow and say we're not in the euro anymore."
Greece's departure from the euro would also harm the European banking sector, said Bob Sinche, the head of foreign exchange strategy at the Royal Bank of Scotland.
"The risks to the eurozone banking system and economy are so great that eurozone leaders would resist this pretty significantly," Sinche said.
Greece could default on its debts if it withdrew from the euro, harming the European banks that own its bonds. Sinche added that Greece's departure would increase risks for Portugal and Ireland, the euro bloc's weakest countries.
