NEW YORK, March 31 (Reuters) - The euro advanced in the first quarter, boosted by expectations of euro zone rate hikes following Thursday's strong inflation numbers, but gains could stall in the next few weeks due to nagging peripheral debt concerns.
Technical indicators suggested the euro was in the midst of a correction to the downside against the dollar after gaining 6 percent in 27 days from the currency's low of $1.3428 on Feb. 14 to last week's high at $1.4249.
The $1.4249 level is the pair's resistance, and if that goes, euro bulls could target $1.4283, the Nov 4 peak.
On the way down, analysts said a strong break below the key $1.4000 psychological level would signal a shift in the euro's uptrend, with downside support at $1.3850.
More importantly, the fundamental outlook for the euro zone remains cloudy, particularly at the periphery, even though an interest rate increase seemed imminent at a European Central Bank monetary policy meeting next week.
"In our view, the euro will weaken on a longer-term horizon ... There's an awful lot of (rate hikes) priced in at the moment and that's because of the change in language from ECB President (Jean-Claude) Trichet," said Frances Hudson, investment director for strategy at Standard Life Investments in Edinburgh.
Standard Life has assets under management of about $214 billion and the firm maintains a long dollar/short euro position in its Global Absolute Return Strategy portfolio.
"If the ECB does hike, they would not hike massively. One percent to 1.25 is not a big leap. After the first move, they will wait and give it time and see what happens," Hudson said.
The latest challenge to the euro zone was a bank stress test in Ireland released on Thursday, which indicated that the country's banks need another 24 billion euros in capital to plug potential losses. For more, click on [

In early afternoon trading, the euro rose 0.5 percent to $1.4194 <EUR=EBS>. It has gained more than 6 percent against the dollar and 8.5 percent against the yen in the first quarter, largely due to the outlook that the ECB would raise rates well before the Federal Reserve and the Bank of Japan. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Asset returns in Q1 2011 graphic: http://r.reuters.com/wur78r Key events in Q1 2011 timeline: http://r.reuters.com/saj68r ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^>

Against the yen, the euro <EURJPY=EBS> was up 0.6 percent at 117.75 after hitting a 10-month high at 117.90 yen.
In the options market, benchmark volatilities implied by one-month at-the-money euro/dollar options <EUR1MO=> fell to 9.3 percent on Thursday, a one-year low, suggesting euro zone debt worries were not at the forefront for investors.
Six-month <EUR6MO=> and one-year implied vols <EUR1YO=> remained elevated though, trading at 11.5 percent and 12.35 percent respectively.
Markets were also looking to Friday's U.S. payrolls report, which could likely dictate the euro's direction against the dollar in the near term.
Economists polled by Reuters have estimated 190,000 jobs were added to non-farm payrolls in March after payrolls expanded by 192,000 jobs in February. (Additional reporting by Julie Haviv; Editing by Dan Grebler)
