Že od leta 2001 je vse več državam Evropske in monetarne unije skupna denarna valuta evro. Za uvedbo slednje mora država kandidatka izpolnjevati konvergenčne kriterije, kar pomeni, da ne sme imeti previsoke inflacije, javnega dolga, javnofinančnega primanjkljaja in obrestne mere. Uvedba sama je prinesla tako pozitivne kot negativne posledice tako na gospodarstvo, kot na politiko in vsakodnevno življenje. Čeprav omogoča preprostejše trgovanje na evropskem trgu, pa članice evroobmočja izgubijo svojo monetarno avtonomijo in nosijo posledice slabega delovanja drugih držav. Dober primer tega je aktualna grška finančna kriza, ki pa bi se lahko razširila tudi na druge države EU. V podobnih težavah bi se lahko kmalu znašle tudi ostale države skupine PIGS, to so Portugalska, Irska in Španija, kar bi gotovo resno ogrozilo stabilnost evra. Since 2001 a growing number of the European countries have been using a common currency, the Euro. In order to introduce the latter each candidate country must meet the convergence criteria, meaning it shouldn't have high inflation rates, public debt, budget deficit and interest rates. Introduction of the Euro has positive as well as negative effects on the economy as well as on politics and everyday life. Even though it simplifies trade in the European market, member states of the Euro zone lose their monetary autonomy and carry the consequences of other countries’ mistakes. A fine example of this is the Greek financial crisis that could also spread to other European countries. Other members of the so called PIGS group, Portugal, Ireland and Spain, could also find themselves in similar difficulty which could seriously jeopardise the stability of the Euro.
