 There was a currency crisis that started in the spring of 2008, and on 6 October trading in Iceland's banks was suspended as the government battled to save the economy.An assessment by the OECD 2011 determined that Iceland has made progress in many areas, particularly in creating a sustainable fiscal policy and restoring the health of the financial sector; however, challenges remain in making the fishing industry more efficient and sustainable, as well as in improving monetary policy to address inflation.Iceland's public debt has decreased since the economic crisis, and is the 31st highest in the world by proportion of national GDP.
