Eurostat has collected data on government interventions during the financial crisis for the years 2007 - 2012. The data are presented in two parts of the supplementary tables. Part 1 shows the actual impact of interventions on government deficit. Part 2 shows the actual and potential impact on government debt. Eurostat publishes individual tables for EU Member States (where there were reportable interventions) and a summary table with the aggregated data for the EU and the Euro area:
Eurostat also publishes a "Statistics in Focus" on financial crisis impact on EDP deficit/surplus and a background note providing more information on the content of the supplementary tables and data findings:
