The story is a bit out-of-date, but this overview of the cause and effects of the Icelandic financial crisis is still worth a read.
Picture a pig trying to balance on a mouse's back and you'll get some idea of the scale of the problem. In a mere seven years since bank deregulation and privatisation, Iceland's financial institutions had managed to rack up $75bn of foreign debt. In his address to the nation, Haarde put the problem in perspective by referring to the $700bn financial rescue package in America: "The huge measures introduced by the US authorities to rescue their banking system represent just under 5 per cent of the US GDP. The total economic debt of the Icelandic banks, however, is many times the GDP of Iceland."
