LONDON, Feb 10 (Reuters) - The euro edged higher on Wednesday, holding gains made the previous day as the market braced for a European Union summit while traders sought clarity on whether Greece may get help in tackling its fiscal problems.
The euro jumped after traders cited a media report that Germany was said to be considering aid for Greece beyond loan guarantees, but trimmed gains on comments from France that there was no euro zone agreement on an aid package at the moment. [ID:nPAB008165]
Ultimately, the euro made limited headway as concerns about the fiscal positions of several euro zone countries kept investors wary of taking big positions before Thursday's summit.
"The market is to-ing and fro-ing on the prospect of any sort of package to help Greece," said Adam Cole, global head of currency strategy at RBC in London.
"This is an unprecedented situation and there are several conceivable resolutions, and a strong case can be made for any of them, and that is weighing on the euro."
Speculation about possible assistance swirled, with France's Le Monde newspaper saying that a German-led plan for Greece should be finalised on Wednesday after talks with the European Central Bank. [ID:nPAB008166]
Pressure on the euro has eased slightly this week after it took a pounding as gaping deficits not only in Greece but in Portugal and Spain highlighted the dismal financial positions of some euro zone members, undermining stability in the 16-country bloc.
By 1126 GMT, the euro <EUR=> was up slightly on the day at $1.3802, having hit a high for the day of $1.3815, according to Reuters data.
It had climbed a full percent on the day and pulled further away from an 8 1/2-month trough around $1.3580 hit last week.
The euro <EURJPY=R> was up slightly at 123.75 yen as traders took a breather after pushing the single currency up roughly 1.5 percent on Tuesday, its biggest one-day gain since October 2009.
Anticipation of a rescue for Greece has helped to stabilise markets and pull the euro back from the 8 1/2-month low versus the dollar and a near 12-month trough against the yen, but some analysts said any proposed plan would hardly spell the end of the euro's downtrend.
"Any package from EU countries will raise the usual concerns about moral hazard and, perhaps more pertinent in the short term, whether the internal adjustment conditions will be successfully enforced," analysts at Barclays said in a note.
They added that weakness in the euro area economy would keep the currency under selling pressure.
Euro losses were limited on Wednesday as the government bond yield spreads between Greece and Germany -- considered by far the safest of euro zone debt -- continued to narrow, suggesting that jitters about Greece may be fading slightly.
Analysts said the currency market wanted to see whether a concrete plan for Greece would materialise at the summit, and that the euro may benefit if peripheral spreads contract more.
The market also awaited comments by Federal Reserve Chairman Ben Bernanke who is expected on Wednesday to outline the Fed's strategy for tightening. The prepared testimony will be released at 1500 GMT, even though the congressional hearing has been postponed.
