What was the beginning year of the European debt crisis that particularly affected Portugal, Italy, Greece, and Spain?
European debt crisis The European debt crisis (often also referred to as the Eurozone crisis or the European sovereign debt crisis) is a multi-year debt crisis that has been taking place in the European Union since the end of 2009. Several eurozone member states (Greece, Portugal, Ireland, Spain and Cyprus) were unable to repay or refinance their government debt or to bail out over-indebted banks under their national supervision without the assistance of third parties like other Eurozone countries, the European Central Bank (ECB), or the International Monetary Fund (IMF).
Euro convergence criteria The euro convergence criteria (also known as the Maastricht criteria) are the criteria which European Union member states are required to meet to enter the third stage of the Economic and Monetary Union (EMU) and adopt the euro as their currency. The four main criteria, which actually comprise five criteria as the "fiscal criterion" consist of both a "debt criterion" and a "deficit criterion", are based on (ex article 121.1) of the Treaty on the Functioning of the European Union.
