The chart below tracks the economy of the United States and selected European economies, demonstrating the varying impact of the financial crisis there. March 2007 is the reference point where Real GDP is re-based at 100.
You can see from the chart, that the US had the sharpest fall in GDP through March 2009 when the policy response finally kicked in and the economy began to grow again. After that time, Greece, Ireland and Italy were the worst performers, with Greece showing the most marked deterioration from April 2010. Switzerland, the Netherlands and Germany have performed the best.
