Dissolution of Czechoslovakia
On 1 January 2009 Slovakia adopted the Euro as its currency with the exchange rate of 30.126 SK/€, and the €2 commemorative coin for 2009, Slovakia's first, featured the 20th anniversary of the Velvet Revolution in remembrance of the common struggle of the Czechoslovak people for democracy. By a quirk of fate, the welcoming speech on the behalf of the European Union on the occasion of Slovakia's entry to the Eurozone was delivered by Mirek Topolánek, the prime minister of the then-EU presiding country, the Czech Republic, naturally in his native language while other guest speakers used English. The Czech Republic continues to use the Czech koruna, or crown.
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.
