BRUSSELS, April 28 (Reuters) - The European Commission forecast on Monday that Slovak inflation would ease in 2009 after hitting a peak this year, and Bratislava officials said this boded well for the country's plan to adopt the euro next January.
In a twice-yearly forecast, the European Union executive said Slovakia's annual inflation would fall to 3.2 percent in 2009 on the EU measure (HICP), after peaking at 3.8 percent in 2008. This compared with 1.9 percent last year.
The forecast did not include the 12-month average inflation rate which is used to assess whether countries are fit to adopt the euro. But it offered some reassurance about Slovakia's ability to keep price growth in check.
"The European Commission forecasts confirm we are able to meet the inflation criterion in a sustainable way in the future," Slovak Finance Minister Jan Pociatek told reporters, echoing comments from central bank board member Peter Sevcovic.
The Slovak crown hit an all-time high of 32.200 to the euro <EURSKK=> on Monday, firming 0.6 percent before easing to 32.225 at 1038 GMT, above the previous all-time high of 32.250 seen in March.
Analysts and politicians have said Slovakia's uncertain inflation outlook is its only obstacle to adopting the currency now shared by 15 nations. Slovakia joined the EU in 2004.
The Commission will recommend on May 7 whether Slovakia should adopt the euro next Jan. 1, following the example of other EU newcomers Slovenia, Cyprus and Malta which have all joined the common currency area.
EU finance ministers will take a final decision in June.
"Since the last quarter of 2007, rapidly growing food and energy prices have resulted in gradually rising HICP inflation, which is expected to peak in the third quarter of 2008," the Commission said on Slovakia.
"Favourable base effects at the end of 2008 should ensure some moderation in the inflation rate, especially if second-round effects are kept in check and there is no further surge in commodity prices at the world markets."
The Commission said euro zone inflation was expected to leap to 3.2 percent in 2008 from 2.1 percent last year before slowing to 2.2 percent in 2009.
STRONG GROWTH
Slovakia's government and central bank are optimistic about their euro bid although European Central Bank sources have previously said the ECB is worried about its inflation outlook. The ECB will also report on Slovakia's euro readiness on May 7, but its findings will not be binding under EU rules.
At the moment Slovakia meets all the euro zone entry criteria on inflation, the budget deficit, public debt, long-term interest rates and currency stability.
Slovakia's 12-month average inflation was 2.2 percent in March, comfortably below the permitted ceiling of 3.2 percent.
Under EU rules, a country wanting to join the euro must have inflation no higher than 1.5 percent percentage points above the average of the three EU members with the lowest inflation rates.
But the EU treaty also says the criterion has to be met in a sustainable way, casting some doubts about Slovakia's bid.
"It's broadly positive, although the forecasts don't completely rule out a surprise decision," said Dresdner Kleinwort analyst Raffaella Tenconi. "I'll stick with my view (that there is a) 70 percent chance Slovakia is in, and 30 percent that they aren't."
Inflation trends are not easy to predict and the Commission is keen to avoid another embarrassment after it deemed in 2006 that Slovenia's inflation was sustainably low. Once Slovenia had adopted the euro last year its inflation rose to a record high.
The Commission also forecast Slovakia would have the highest economic growth rate of the EU's 27 nations, with gross domestic product expected to expand 7.0 percent in 2008 and 6.2 percent in 2009, compared with 10.4 percent last year.
Despite a strong appreciation of the crown currency, Slovak exports are expected to outpace imports, it said, although economic growth will be driven mainly by domestic demand.
Prime Minister Robert Fico said on Monday his government would seek to negotiate as strong as possible a conversion rate for the planned 2009 euro adoption. (Additional reporting by Peter Laca and Martin Santa in Bratislava)
