Title: Czech koruna
Content:  Czech koruna, also known as Czech Crown, (sign: Kč; code: CZK, Czech: koruna česká) has been the currency of the Czech Republic since 1993. The koruna is one of the European Union's 11 currencies, and the Czech Republic is legally bound to adopt the euro currency in the future. The official name in Czech is koruna česká (plural koruny české, though the zero-grade genitive plural form korun českých is used on banknotes and coins of value 5 Kč or higher). The ISO 4217 code is CZK and the local acronym is Kč, which is placed after the numeric value (e.g., "50 Kč") or sometimes before it (as is seen on the 10-koruna coin). One koruna equals 100 haléřů (abbreviated as "h", singular: haléř, nominative plural: haléře, genitive plural: haléřů – used with numbers higher or equal to 5 – e.g. 3 haléře, 8 haléřů), but haléře have been withdrawn, and the smallest unit of physical currency is 1 Kč. Despite its withdrawal haléře are still present in prices of various products, but are rounded to koruna at checkout.

Title: Dissolution of Czechoslovakia
Content:   Initially, the old Czechoslovak currency, the Czechoslovak koruna, remained in use by both countries. Czech fears of an economic loss caused the adoption two national currencies as early as February 8, 1993. At the beginning, the currencies had an equal exchange rate, but the value of the Slovak koruna was then usually lower than that of the Czech koruna (in 2004, around 25–27% lower). On August 2, 1993, both currencies were distinguished by different stamps that were first affixed to and then printed on old Czechoslovak koruna banknotes. On January 1, 2009, Slovakia adopted the euro as its currency with an 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 Czechoslovaks 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 presiding country, the Czech Republic, naturally in his native language, but the other guest speakers used English. The Czech Republic continues to use the Czech koruna, or crown.

The Czech Republic also receives €24.2bn between 2014 and 2020 from the European Structural and Investment Funds, however, this sum does not outweigh the amount of capital outflow of profits of foreign owned firms from the Czech Republic into other EU members, at which the funds are aimed to compensate for.

The Czech Republic participates in the European Single Market as a member of the European Union and is therefore a part of the economy of the European Union, but uses its own currency, the Czech koruna, instead of the euro.

Title: Czechoslovak koruna
Content:  The Czechoslovak koruna (in Czech and Slovak: Koruna československá, at times Koruna česko-slovenská; koruna means crown) was the currency of Czechoslovakia from April 10, 1919, to March 14, 1939, and from November 1, 1945, to February 7, 1993. For a brief time in 1939 and again in 1993, it was also the currency in the separate Czech Republic and Slovakia. On February 8, 1993, it was replaced by the Czech koruna and the Slovak koruna, both at par. The (last) ISO 4217 code and the local abbreviations for the koruna were CSK and Kčs. One koruna equalled 100 haléřů (Czech, singular: haléř) or halierov (Slovak, singular: halier). In both languages, the abbreviation h was used. The abbreviation was placed behind the numeric value.
Title: Czech National Bank
Content:  The CNB maintains exclusive rights to issue and regulate banknotes and coins. The Bank oversees the legal and technical protection of the currency, the Koruna (also called the Crown). The Czech Republic was scheduled to adopt the Euro in 2010, but due to popular opinion, the Czech government opted to stay with the crown. Consequently, the implementation of the Euro was suspended indefinitely. The Czech National Bank issues 1Kč, 2 Kč, 5 Kč, 10 Kč, 20 Kč and 50 Kč coins. The note denominations consist of 100 Kč, 200 Kč, 500 Kč, 1,000 Kč, 2,000 Kč and 5,000 Kč.

In 1993, on the breakup of Czechoslovakia, the Czechoslovak koruna split into two independent currencies: the Slovak koruna and the Czech koruna. Accession to the EU in 2004 meant both currencies were slotted to be replaced by the euro once their respective countries met the criteria for economic convergence and there was the political will to do so. The Slovak koruna was replaced by the euro on 1 January 2009; there is currently no set or estimated date for the Czech koruna to be replaced.
Title: Czech National Bank
Content:  The Czech Republic officially joined the European Union on 1 May 2004. The original intention of the Czech National Bank was to adopt the Euro, but after relatively strong economic progress within the Czech Republic and a favorable national attitude for the Czech Koruna there are no current plans to change the currency. With no political or public urgency, the Czech Republic will most likely not join the Euro Area and adopt the Exchange Rate Mechanism in the coming years.
