History of the euro
Slovakia fulfilled the euro convergence criteria. At 2.2%, Slovakia's twelve-month inflation was well below the 3.2% threshold. However, for March 2008 annual inflation was 3.6%. Fiscal deficit was 2.2% versus the reference value of 3.0%. And finally, the government debt ratio was 29.4% of GDP in 2007, well below the maximum ratio of 60.0%. Public opinion supported the switch, with 58% in favour and 35% opposed, but 65% worried about the inflationary impacts of the adoption. Three months after the adoption of the currency 83 percent of Slovaks consider Slovakia's decision to adopt the euro to have been right.
Slovak koruna
The graph shows the value of the euro in korunas from 1999 to December 2008. As may be seen, the currency strengthened as Slovakia's economy did. The koruna joined the ERM II on 28 November 2005 at the rate of € = 38.4550 Sk with a 15% band. On 17 March 2007, this rate was readjusted to 35.4424 Sk with the same band, an 8.5% increase in the value of the koruna. On the same day, 1 euro traded at 33.959 Sk. The central rate of koruna was then adjusted once more on 28 May 2008 to 23.8545 with no change in the band.
