Despite speculation that the Greek crisis could spread and that the euro could fail, some new EU Member States joined the currency after enlargement in 2004 during the recession. Slovenia, Malta and Cyprus all joined the recession in the first two years, closely followed by Slovakia in 2009. The three Baltic states, Estonia, Latvia and Lithuania, joined in 2011, 2014 and 2015 respectively. Economic and Monetary Union (EMU) has been a recurring target for the European Union since the late 1960s. EMU includes the coordination of economic and fiscal policies, a common monetary policy and a common currency, the euro. A single currency has many advantages: it facilitates cross-border trade for businesses, the economy becomes more stable and consumers have more choices and opportunities. The first phase of the launch of the euro took place in 1999. It was introduced as currency for electronic payments. These include credit and debit cards, loans and accounting purposes. In this initial phase, the old coins were only used for cash.
Eleven nations accepted it immediately. These included Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Portugal and Spain. The treaty also provides for the possibility of applying the banking system of the single currency to regulate European financial markets to support an expansionary policy- potentially inflationary. “State Enterprises” or the acquisition of debt securities.  The transition may have been quick and silent. But the path to a common European currency has been a bumpy transition from economic confusion to possible unity. Here is a brief history of the money that came to define the hopes of the European Union. Slovakia met the convergence criteria of the euro.
12-month inflation in Slovakia was well below the 3.2% threshold, at 2.2%. However, in March 2008, the annual inflation rate was 3.6%. The budget deficit was 2.2% compared to the 3.0% reference value. Finally, in 2007, the public debt ratio stood at 29.4% of GDP, well below the ceiling of 60.0%.  Public opinion supported the change with 58% in and 35% against, but 65% were concerned about the inflationary effects of the hypothesis.  Three months after the introduction of the currency, 83% of Slovaks felt that Slovakia`s decision to adopt the euro was the right one.  The introduction was relatively fluid, despite the refusal of some countries, such as the United Nations and Denmark, to use currency and strikes by angry bankers, both in France and Italy.
