The Greek government-debt crisis is one of a number of current European sovereign-debt crises. In late 2009, fears of a sovereign debt crisis developed among investors concerning Greece's ability to meet its debt obligations because of strong increase in government debt levels.[1][2][3] This led to a crisis of confidence, indicated by a widening of bond yield spreads and the cost of risk insurance on credit default swaps compared to the other countries in the Eurozone, most importantly Germany.[4][5]
