The Icelandic financial crisis was a major economic and political event in Iceland that involved the default of all three of the country's major privately owned commercial banks in late 2008, following their difficulties in refinancing their short-term debt and a run on deposits in the Netherlands and the United Kingdom. Relative to the size of its economy, Iceland's systemic banking collapse was the largest experienced by any country in economic history. The crisis led to a severe economic slump in 2008–2010 and significant political unrest.
