LONDON, April 22 (Reuters) - Slovakia will become the newest member of the euro club when it adopts the currency next year but other Eastern European nations are several years away, a Reuters poll showed.
A poll of 29 analysts and strategists, taken April 11-22, found Estonia and Lithuania joining the euro zone in 2012, and the Czech Republic, Latvia and Poland in 2013.
Bulgaria's entry was not expected until 2014, a year later than forecast in a January poll, while Hungary was seen joining in 2014 and Romania in 2015, the same as in January.
"Our outlook for euro adoption in Central Europe has overall become somewhat less optimistic. The main drive for this is the recent surge in inflation combined with the continued external imbalances," said Dagmar Alpen at Oppenheim.
Spiralling inflation and controlling budget deficits are seen as the biggest hurdles for all potential candidates before they ditch local currencies.
The fiscal effect forced the Czech government to abandon plans to adopt the euro in 2009-2010, while inflation -- and the ability to maintain low price growth sustainably -- could potentially scupper Slovakia's early entry.
A condition of entry to the euro zone is that government deficits must not exceed 3 percent of gross domestic product and inflation must be no more than 1.5 percentage points higher than an average of the three lowest among EU states.
CURRENCY VALUATIONS
Slovakia was seen revaluing its currency within the next 12 months before adopting the euro in 2009, but 13 of 19 said it would not be able to hold its inflation rate within the Maastricht criteria for two years after ditching the crown.
"Ensuring that medium-term inflation will remain under control could prove problematic and may be used as a justification to delay accession," said Sharon Fisher at Global Insight, who predicts Slovakia will sign up in 2009.
"Still, we see any delays as rather unlikely."
The Czech Republic may revalue its currency within the next 12 months, said seven of 14 analysts, while five of 13 and five of 16 saw Romania and Hungary respectively devaluing their currencies within the year.
Poland's new centre-right Civic Platform government is more pro-euro than the previous conservatives but says euro zone entry is unlikely before its term ends in 2011.
Estonian central bank Governor Marten Ross has also said it was unrealistic for his country to adopt the euro before 2011 and Czech Prime Minister Mirek Topolanek said this month his administration was in no hurry to enter the euro zone. Malta and Cyprus took euro zone membership to 15 countries earlier this year, but added only 0.2 percent to the region's economy.
The euro <EUR=> hit a record high against the dollar last week as high inflation data cemented views the European Central Bank would hold interest rates steady as the U.S. Federal Reserve continues to slash rates to fight off a recession.
EU ENTRY
Analysts see Croatia as the next entrant to the European Union, following Romania and Bulgaria's entry last year, but not until 2009 at the earliest, with a median forecast entry date of 2011.
Macedonia, Montenegro and Serbia are seen joining the 27-member bloc in 2015, Albania and Bosnia will sign up in 2016, while Turkey will not join until 2020, according to the Reuters poll.
Turkey began membership talks in 2005 but negotiations have slowed sharply amid disputes over penal reforms, human rights and the division of Cyprus into an internationally recognised Greek Cypriot south -- an EU member -- and a breakaway Turkish Cypriot state.
Analysts gave a median 30 percent probability that the EU would suspend negotiations with Turkey and the same chance that Turkey would pull out. This compares to 20 and 25 percent respective forecasts in January's poll.
"While the Turkish government insists that it remains committed to EU membership, the pace of reform has slowed down considerably over the past couple of years," said James Ker-Lindsay at Kingston University.
