From late 2009, fears of a sovereign debt crisis in some European states developed, with the situation becoming particularly tense in early 2010.^[1][2] Greece was most acutely affected, but fellow Eurozone members Cyprus, Ireland, Italy, Portugal, and Spain were also significantly affected.^[3][4] In the EU, especially in countries where sovereign debt has increased sharply due to bank bailouts, a crisis of confidence has emerged with the widening of bond yield spreads and risk insurance on credit default swaps between these countries and other EU members, most importantly Germany.^[5]

This was the first Eurozone crisis since its creation in 1999. As Samuel Brittan pointed out,^[6] Jason Manolopoulos "shows conclusively that the Eurozone is far from an optimum currency area".^[7] Niall Ferguson also wrote in 2010 that "the sovereign debt crisis that is unfolding... is a fiscal crisis of the western world".^[8] Axel Merk argued in a May 2011 Financial Times article that the dollar was in graver danger than the euro.^[9]

Concern about rising government deficits and debt levels^[10][11] across the globe together with a wave of downgrading of European government debt^[12] created alarm in financial markets. The debt crisis is mostly centred on events in Greece, where the cost of financing government debt has risen. On 2 May 2010, the Eurozone countries and the International Monetary Fund agreed to a €110 billion loan for Greece, conditional on the implementation of harsh austerity measures.^[13] On 9 May 2010, Europe's Finance Ministers approved a comprehensive rescue package worth €750 billion (then almost a trillion dollars) aimed at ensuring financial stability across Europe by creating the European Financial Stability Facility.^[14] The Greek bail-out was followed by an €85 billion rescue package for Ireland in November,^[15] and a €78 billion bail-out for Portugal in May 2011.^[16][17]

While the sovereign debt increases have been most pronounced in only a few Eurozone countries they have become a perceived problem for the area as a whole.^[18] In May 2011, the crisis resurfaced, concerning mostly the refinancing of Greek public debt.^[19] The Greek people generally rejected the austerity measures and have expressed their dissatisfaction with protests.^[20][21] In late June 2011, the crisis situation was again brought under control with the Greek government managing to pass a package of new austerity measures and EU leaders pledging funds to support the country.^[22] In May 2012 the crisis escalated to new levels following the national Greek legislative election, May 2012. Greek parties failed to form a coalition Government following the election and there was widespread speculation of Greece exiting the Eurozone, termed a "Grexit".

Below is a brief summary of some of the main events since the Greek government debt crisis.^[23]
