(Adds crown jump in para 3, analyst comments in paras 13-15)

BRATISLAVA, Feb 22 (Reuters) - Slovakia should seek to negotiate a switchover rate to the euro that would reflect expected economic developments and help to reduce inflation risks after euro zone entry, a central bank vice-governor said.
Speaking to Reuters in a rare interview on Friday, Vice-Governor Martin Barto declined to comment on what could be the conversion rate, which is expected to be agreed between the Slovak government and European Union authorities by end of July.
The crown firmed as much as 0.7 percent per euro near record highs after Barto's comments as investors said they suggested the conversion rate could be stronger than recent market levels.
Slovakia plans to become the 16th member of euro zone in 2009, and its adoption process is seen as a test case for the rest of central Europe as it would be the first ex-communist country with a floating exchange rate to adopt the euro. Speculation about the conversion rate has been a key factor in crown movements and investors look for any signs of Bratislava's negotiation position.
Barto said Slovakia should advocate a conversion rate justified by the strength of the economy, but the agreed level should not reflect only past economic performance.
"In my view, negotiations on the conversion level should reflect a real equilibrium exchange rate, which means a rate based on fundamentals of the economy," Barto said.
"But it would be beneficial for Slovakia if the conversion rate also reflected future developments in economic fundamentals, which we can, to a certain degree, already estimate at present." The crown hit 32.740 per euro <EURSKK=>, on Friday, which is 7.6 percent stronger than the central parity rate, in the exchange rate mechanism ERM-2 within which a euro applicant country must demonstrate currency stability.
The local unit is still weaker than its all-time highs of 32.710 to the euro in March 2007 after Slovakia revalued the ERM-2 parity rate by 8.5 percent, to 35.4424 per euro, following strong productivity growth and economic expansion.
The Slovak economy continued to grow rapidly throughout 2007, expanding by a record 10.3 percent for the whole of last year, as foreign investment fuelled export-oriented industries.
Barto would not comment on where the present or future equilibrium value could be, while analysts say the growing economy would justify a conversion rate stronger than current market levels.
"The recent and current levels were not in line with fundamentals of the economy," said Jan Toth, chief economist at ING Bank in Bratislava.
Toth said a conservative view put the real equilibrium exchange rate at around 32.0 per euro for the start of 2009.
But if future investments and capacity growth in key car and electronics industries are included in the calculation, Toth said, the equilibrium rate for the start of next year would move even further, possibly as far as around 31.50 per euro.
INFLATION RISKS
Senior NBS officials have said 2007 economic growth was healthy and did not create additional upward pressure on inflation.
The bank has held the main two-week interest rate steady at 4.25 percent since April last year, which has preserved a 25 basis points premium over the main euro zone rate. It repeatedly said the rising crown had tightened monetary conditions.
But Slovakia will have to cut its main rate to unite it with European Central Bank (ECB) level as part of the euro adoption process, a move that will loosen local monetary conditions.
Barto said an appropriately set conversion rate should also help to counter future inflation risks after euro zone entry takes away the effect of the firming crown on consumer prices.
"The negotiations should take into account more relaxed monetary conditions (after euro adoption), and future inflation risks," Barto said.
Keeping inflation under control is Slovakia's key challenge on its way to euro zone entry. The key price growth yardstick hit a one-year peak of 2.5 percent in December, on higher cost of food and petrol fuels, but it still stayed under the euro adoption threshold for the fifth consecutive month.
