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.
Swedish krona
The krona (; plural: "kronor"; sign: kr; code: SEK) is the official currency of Sweden. Both the ISO code "SEK" and currency sign "kr" are in common use; the former precedes or follows the value, the latter usually follows it but, especially in the past, it sometimes preceded the value. In English, the currency is sometimes referred to as the Swedish crown, as "krona" literally means crown in Swedish. The Swedish krona was the ninth-most traded currency in the world by value in April 2016.
