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
Initially, the Slovak koruna was at par with the Bohemian and Moravian koruna, with 10 korunas = 1 Reichsmark. It was devalued, on 1 October 1940, to a rate of 11.62 Slovak korunas to one Reichsmark, while the value of the Bohemian and Moravian currency remained unchanged against the Reichsmark.
