There is little consensus on the macroeconomic impacts of sovereign debt crises, despite the regularity of such events. This column quantifies the aggregate costs of defaults using a narrative approach on a large panel of 50 sovereigns between 1870 and 2010. It estimates significant and persistent negative effects of debt crises starting at 1.6% of GDP and peaking at 3.3%, before reverting to trend five years later. In addition, underlying causes matter. Defaults driven by aggregate demand shocks result in short-term contractions, whereas aggregate supply shocks lead to larger, more persistent losses.
