From late 2009, fears of a sovereign debt crisis in some European states developed, with the situation becoming particularly tense in early 2010. Greece was most acutely affected, but fellow Eurozone members Cyprus, Ireland, Italy, Portugal, and Spain were also significantly affected. 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.
