🇨🇿Czech Koruna (CZK)

The word koruna means crown and the currency descends from the Austro-Hungarian krone introduced in 1892. When Czechoslovakia dissolved on 1 January 1993 the two successor states briefly shared a currency, then separated it within weeks: notes were stamped to mark which country they belonged to before new ones were issued, and Slovakia's koruna went its own way until it adopted the euro in 2009. The subunit, the haléř, was withdrawn from circulation in 2008, so cash totals are rounded to the whole koruna while electronic prices are still quoted with decimals.

Between November 2013 and April 2017 the Czech National Bank ran an unusual policy: with interest rates already at zero, it made a one-sided commitment to stop the koruna strengthening past a declared level against the euro, intervening as often as needed to hold it. When the commitment was lifted the currency floated again. Czechia is an EU member and is in principle committed to adopting the euro eventually, but it has set no target date and does not take part in ERM II, which is why the koruna's euro rate genuinely moves from day to day where the Danish krone's barely does.

The koruna is the sole legal tender of Czechia; some businesses in Prague and in border towns accept euros, but at a rate they set themselves and with change given in koruna.
