LUXEMBOURG, Feb 28 (Reuters) - Slovakia's Finance Minister Jan Pociatek said on Thursday he was not ruling out another "revaluation" of the country's crown currency, sending the unit to record highs against the euro.
The crown is now in the Exchange Rate Mechanism 2, the stability test for joining the euro zone, and floats against the euro in a band of +/- 15 percent on either side of a central parity rate. A revaluation would mean a stronger central parity.
Asked by reporters in Luxembourg whether he was considering such a move and whether it would make sense, Pociatek said:
"It is difficult to comment on this issue in detail, but the possibility of revaluation cannot be excluded."
The Slovak crown <EURSKK=> rose to a record high of 32.525/614 against the euro at 1556 GMT from 32.735 before.
Slovakia hopes to become the 16th member of the euro area from 2009. It needs to meet European Union criteria -- a stable exchange rate, low interest rates and inflation, and debt and budget deficit levels below EU thresholds.
While EU rules do not allow for a currency to be devalued while in the ERM-2, revaluation is not a problem.
Slovakia already revalued the ERM-2 parity peg by 8.5 percent to 35.4424 per euro in March 2007 because of upward pressure on the currency from years of fast GDP growth, large productivity gains and strong foreign investment.
Greece and Ireland also revalued ahead of euro adoption, but by much less than Slovakia has done.
REVALUATION TO FIGHT INFLATION
Slovakia's strong growth creates inflationary pressures, which can now be offset to some extent by the rise in the exchange rate of the crown within the band.
The European Commission is concerned however, that once the exchange rate cushion is gone, inflation pressures may mount. The EU executive arm has therefore urged tighter Slovak budget discipline to keep inflation under control.
But Slovakia has already made substantial budget deficit cuts and the Commission remarks have sparked market speculation that Slovakia could again revalue the crown, possibly at the time when the conversion rate to the euro is set in mid-year, if the country is accepted into the single currency area.
Hungary abandoned a similar trading band for the forint earlier this week in the hope that the currency would appreciate and help fight high inflation.
The issue of sustainability of low inflation came to the fore after price growth in Slovenia, which adopted the euro in 2007, hit 6.4 percent in January, in the highest in the euro zone, from 2.8 percent a year earlier.
EU officials are keen to avoid another "Slovenia" and pay special attention to inflation sustainability, EU sources said.
Year-on-year inflation in Slovakia hit a 13-month high of 3.8 percent in January, fuelled by food and energy prices, but its 12-month average inflation -- the measure used for euro entry -- was still well below the limit of the average of the 3 best EU performers plus 1.5 percentage points.
Fico said on Thursday Slovakia would keep inflation under control, through a special anti-inflationary package if needed.
"We are able to keep inflation under control and we are ready to introduce an anti-inflationary package in order to deal with this issue," he told reporters. "We will do our best to guarantee that we keep inflation under control."
The chairman of euro zone finance ministers Jean-Claude Juncker was optimistic on Slovakia's euro prospects after talks with Slovak Prime Minister Robert Fico and Pociatek.
"In my capacity as Chairman of the Eurogroup I very much admire the extraordinary performance of Slovakia as far as economic reforms and economic success are concerned," Juncker told reporters. "Slovakia is on an excellent track to fulfil all the convergence criteria," he said.
While only the European Commission can formally invite Slovakia into the euro zone, Juncker is a powerful euro zone figure whose backing is valuable. (Additional reporting by Peter Laca in Bratislava) (Writing by Jan Strupczewski; Editing by Jon Boyle)
