The debt increased in 2009 due to the higher-than-expected government deficit and higher debt-service costs. The Greek government assessed that structural economic reforms would be insufficient, as the debt would still increase to an unsustainable level before the positive results of reforms could be achieved. In addition to structural reforms, permanent and temporary austerity measures (with a size relative to GDP of 4.0% in 2010, 3.1% in 2011, 2.8% in 2012 and 0.8% in 2013) were needed. Reforms and austerity measures, in combination with an expected return of positive economic growth in 2011, would reduce the baseline deficit from €30.6 billion in 2009 to €5.7 billion in 2013, while the debt/GDP ratio would stabilize at 120% in 2010–2011 and decline in 2012 and 2013.
