's post as President of the Eurogroup. Due to the
2008 financial crisis and the
Great Recession, the eurozone entered its first official
recession in the third quarter of 2008, official figures confirmed in January 2009. The EU was in negative growth for the second, third and fourth quarters of 2008 and the first quarter of 2009 before returning to positive growth (for the eurozone as a whole). Despite the recession, Estonia acceded to the eurozone and Iceland put in an EU application to join the euro, seeing it at the time as a safe haven.
Lisbon Treaty In 2009, the
Lisbon Treaty formalised the
Eurogroup, the meeting of euro finance ministers, with an official president.
Jean-Claude Juncker served as president before and after formalisation and has been an advocate of strengthening the group, economic co-operation and common representation. Appetite for stronger economic co-operation grew due to the recession and the potential failure of some weaker eurozone members. However, Germany had opposed previous moves to strengthen the Eurogroup, such as
French President Nicolas Sarkozy's attempts at Eurogroup summits, due to fears of undermining the ECB's independence.
Jean-Claude Trichet, who succeeded Duisenberg as ECB president in 2003, fended off numerous attacks from Sarkozy at the start of the recession. Before that formalisation of the Eurogroup, eurozone leaders held an extraordinary summit on 11 October 2008 in Paris to discuss the
2008 financial crisis. Rather than the Eurogroup meeting as finance ministers, they met as head of states or government (similar to the
European Council) to define a joint action plan for the eurozone and the European Central Bank to stabilise the
European economy. These such meetings would be where many euro governance reforms would be agreed.
Early responses The leaders designed a plan to mitigate the
2008 financial crisis which will involve hundreds of billions of euros of new initiatives to head off a feared meltdown. They agreed a bank rescue plan: governments would buy into banks to boost their finances and guarantee
interbank lending. Coordination against the crisis is considered vital to prevent the actions of one country harming another and exacerbating the bank solvency and credit shortage problems. Despite initial fears by speculators in early 2009 that the stress of such a large recession could lead to the break-up of the eurozone, the euro's position actually strengthened as the year progressed. Far from the poorer performing economies moving further away and becoming a default risk, bond yield spreads between Germany and the weakest economies decreased easing the strain on these economies. Much of the credit for the turn around in fortunes has been attributed to the ECB, which injected €500bn into the banks in June. Indeed, the euro came to be seen as a
safe haven, as countries outside it such as Iceland fared worse than those with the euro. Iceland subsequently applied to the EU to get the benefit of using a larger currency with the support of the ECB.
Bailout funds However, with the risk of a
default in Greece and
other members in late 2009–10,
eurozone leaders agreed to provisions for bailing out member states who could not raise funds (triggered for Greece in April 2010). This was a U-turn on the EU treaties, which rule out any bailout of a euro member to encourage members to manage their finances better. Yet with Greece struggling to restore its finances, other member states also at risk and the repercussions this would have on the rest of the eurozone economy; a temporary bail out mechanism was agreed and devised in the form of a
special-purpose vehicle (SPV) named "
European Financial Stability Facility" (complemented by the
European Financial Stabilisation Mechanism and funds form the
International Monetary Fund), aiming at preserving financial stability in Europe by providing financial assistance to eurozone states in difficulty. The crisis also spurred consensus for further economic integration and a range of proposals such as a "European Monetary Fund" or federal treasury. However, in June 2010, broad agreement was finally reached on a controversial proposal for member states to peer review each other's budgets prior to their presentation to
national parliaments. Although showing the entire budget to each other was opposed by Germany, Sweden and the UK, each government would present to their peers and the Commission their estimates for growth, inflation, revenue and expenditure levels six months before they go to national parliaments. If a country was to run a deficit, they would have to justify it to the rest of the EU while countries with a debt more than 60% of GDP would face greater scrutiny. The plans would apply to all EU members, not just the eurozone, and have to be approved by EU leaders along with proposals for states to face sanctions before they reach the 3% limit in the
Stability and Growth Pact. Poland has criticised the idea of withholding regional funding for those who break the deficit limits, as that would only impact the poorer states. In late 2010/early 2011, it was agreed to replace the European Financial Stability Facility and European Financial Stability Mechanism with a larger and permanent
European Stability Mechanism (ESM). The ESM required a treaty amendment to allow it and a separate treaty to establish it but, if ratified successfully, would be established in time to take over when the old facilities expire in 2013. Meanwhile, to support Italy and prevent it having to ask for a bail-out later, the ECB controversially started buying Italian bonds, as it had done with Greece.
Fiscal agreements In March 2011 was initiated a new reform of the
Stability and Growth Pact aiming at straightening the rules by adopting an automatic procedure for imposing of penalties in case of breaches of either the deficit or the debt rules. The
Euro Plus Pact sets out a wide range of reforms to take place in the eurozone to ensure and the French and German governments further agreed to push for a 'true economic government' that would involve twice-yearly eurozone leader summits and a financial transactions tax. The
European Fiscal Union is a proposal for a treaty about
fiscal integration described in a decision adopted on 9 December 2011 by the European Council. The participants are the eurozone member states and all other EU members without the United Kingdom and the
Czech Republic. The treaty entered into force on 1 January 2013 for the 16 states which completed ratification prior of this date and on 1 April 2014 entered into force for all 25 signatories.
Enlargements Despite speculation that the crisis in Greece could spread and that the euro might fail, some newer EU states from the
2004 enlargement joined the currency during the recession. Slovenia, Malta and Cyprus all acceded within the first two years of the recession, closely followed by Slovakia in 2009. The three Baltic states of Estonia, Latvia and Lithuania joined in 2011, 2014 and 2015, respectively. Eight years later,
Croatia joined in 2023, while three years after that,
Bulgaria joined in 2026.
Slovenia Slovenia was the first country to join the eurozone after the launch of the coins and banknotes. Participation in ERM II began on 28 June 2004 and on 11 July 2006 the Council of EU adopted a decision allowing Slovenia to join the euro area as from 1 January 2007, becoming the first nation from the former
Socialist Federal Republic of Yugoslavia to do so. The euro replaced the
Slovenian tolar on 1 January 2007. The exchange rate between the euro and tolar had been set on 11 July 2006 at 239.640 SIT, but unlike the previous launches, cash and non-cash transactions were introduced simultaneously.
Cyprus Cyprus replaced the
Cypriot pound with the euro on 1 January 2008. A formal letter of application to join the eurozone was submitted on 13 February 2007. On 16 May 2007 the
European Commission, backed by the
European Central Bank, gave its go-ahead for the introduction in January 2008. The campaign to inform the citizens of Cyprus about the euro officially began in Cypriot media on 9 March 2007. On 15 March 2007, the Cypriot House of Representatives passed the necessary laws for the introduction of the euro on 1 January 2008. The
European Commissioner for Economic & Financial Affairs Joaquín Almunia, on 16 May 2007, recommended that Cyprus adopt the euro as scheduled, and the
European Parliament concurred on 21 June 2007; the date was confirmed by the EU leaders. The final decision was taken by the EU finance ministers (
Ecofin) on 10 July 2007 and the conversion rate was fixed at 0.585274 CYP. On 23 October 2007, the
coin designs were officially published in the
Official Journal of the European Union. On 1 January 2008, the euro replaced the Cypriot pound as the official currency. The euro is only used in the government-controlled areas of the Republic, the
Sovereign Base Areas of
Akrotiri and Dhekelia (under UK jurisdiction, outside the EU) and in the
United Nations Buffer Zone in Cyprus. The
de facto Turkish Republic of Northern Cyprus continues to use the
new Turkish lira as its primary currency and the euro as its secondary currency.
Malta covered with floor designs of their new euro coins Malta replaced the
Maltese lira with the euro on 1 January 2008. On 16 May 2007, the Commissioner for Economic & Financial Affairs of the EU,
Joaquín Almunia, recommended that Malta adopt the euro as scheduled, a decision later confirmed by the Council of Finance Ministers of 10 July 2007. On the same day, dual displaying became mandatory and the first Maltese euro coins were struck at
Monnaie de Paris. The first Maltese euro coins were available for the public on 1 December 2007, as business starter packs worth €131 each started being available for small businesses to fill up their cash registers with sufficient amount of euro coins before the €-day (Jum €). Mini-kits each worth €11.65 were available for the general public on 10 December 2007. Maltese coins which were current at the time of the euro transition could be exchanged through 1 February 2010. In December 2007, as part of the euro changeover celebrations, streets of
Valletta were covered with carpets depicting euro coins. Celebrations reached climax on New Year's Eve with a firework display near the Grand Harbour area, several other activities had to be moved indoors because of the stormy weather that struck the island on that night.
Slovakia euro coins
starting set Slovakia adopted the euro on 1 January 2009. The
koruna was part of ERM II from 28 November 2005, requiring that it trade within 15% of an agreed central rate; this rate was changed on 17 March 2007 and again on 28 May 2008. The rate of 30.1260 SKK from May 2008 was finally confirmed on 8 July 2008. To assist the process of conversion to the euro, on 1 April 2008, the
National Bank of Slovakia (NBS) announced their plan for withdrawal of the
Slovak koruna notes and coins. A few days later, on 5 April 2008, Slovakia officially applied to enter the eurozone. On 7 May 2008, the
European Commission approved the application and asked member states to endorse the bid during the EU finance ministers' meeting in July 2008. Slovakia fulfilled the
euro convergence criteria. At 2.2%, Slovakia's twelve-month inflation was well below the 3.2% threshold. However, for March 2008 annual inflation was 3.6%. Fiscal deficit was 2.2% versus the reference value of 3.0%. Finally, the government debt ratio was 29.4% of GDP in 2007, well below the maximum ratio of 60.0%. Public opinion supported the switch, with 58% in favour and 35% opposed, but 65% worried about the inflationary impacts of the adoption. Three months after the adoption of the currency, 83 per cent of Slovaks considered Slovakia's decision to adopt the euro to have been right. Publicity for the transition from the koruna to the euro on 1 January 2009 included a "euromobile", with a professional actor driving around the countryside holding impromptu quiz shows about the euro. Winners received euro T-shirts, euro conversion calculators, and chocolate euro coins. Euro starter kits, available for 500 koruna, were a popular Christmas gift in 2008. The coins therein, however, were not valid as legal tender in the eurozone until 1 January 2009, with koruna exchanged through 17 January 2009, though redeemable at the central bank in Bratislava until a date to be determined. Anyone using Slovakian euro coins before 1 January could have been fined. Businesses using the transition to raise prices also were subject to penalty. In 2013, Latvia gained the support of the European Commission, European Central Bank and European Parliament for accession on 1 January 2014, with Latvia adopting the currency on that date. On 23 July 2014
Lithuania became the last
Baltic state to gain permission to join the euro, which was adopted on 1 January 2015.
Croatia Croatia completed its plans to adopt the Euro Currency as soon as possible after the
1 July 2013 EU accession. The country commenced participation in the
ERM II on 10 July 2020 and on 12 July 2022 the Council of EU adopted a currency decision allowing Croatia to join the eurozone from the 1 January 2023. The euro replaced the
Croatian kuna on 1 January 2023. The exchange rate between the euro and kuna had been set on 12 July 2022 at 7.5345 HRK and similar to the previous launch of Slovenia, cash and non-cash transactions were introduced simultaneously on the same day and date the country also entered the
Schengen Area.
Bulgaria Bulgaria adopted the euro on 1 January 2026, making it the 21st member state of the
eurozone. When Bulgaria
joined the EU in 2007 it committed to join the
eurozone and replace its currency, the
lev, with the
euro. In February 2025, the country officially requested off-cycle assessments of their convergence by the
European Commission and
ECB to determine the country's readiness. The 2025 convergence reports published on 4 June 2025 concluded that Bulgaria met the
convergence criteria. On 8 July 2025, the
European Parliament endorsed Bulgaria's entry in the eurozone and the
Council of the European Union adopted the final three legislative acts required for the admission.
