This paper updates the widely used banking crises database by Laeven and Valencia (2008, 2010) with new information on recent and ongoing crises, including updated information on policy responses and outcomes (i.e., fiscal costs, output losses, and increases in public debt). The database includes all systemic banking, currency, and sovereign debt crises during the period 1970–2011. The data show some striking differences in policy responses between advanced and emerging economies as well as many similarities between past and ongoing crises. The paper updates the list of banking crises, presenting a complete list of banking crises for the period 1970–2011. It also presents the updated list of currency and sovereign crises since 1970. The paper presents the policy responses and outcomes in terms of fiscal costs and real costs during banking crises. It concludes that advanced economies tend to experience larger output losses and increases in public debt than emerging and developing countries. These larger output losses in advanced economies are to some extent driven by deeper banking systems, which makes a banking crisis more disruptive. The relatively larger increase in public debt in advanced economies is related to larger output losses and a greater use of countercyclical fiscal policy. The paper also includes data on policy responses for a subset of the 147 episodes identified, allowing for a comparison of the policy mix used to resolve banking crises. It finds that monetary and fiscal policies are used more extensively during banking crises in advanced economies than in emerging and developing countries. One explanation is that advanced economies have better financing options to use countercyclical fiscal policy and generally have more space to use monetary policy. Consistent with the greater reliance on macroeconomic policies in advanced economies, it finds that fiscal outlays associated with financial sector interventions in advanced economies are about half that in emerging and developing countries, despite relatively larger banking systems in advanced economies. The paper also includes data on the occurrence of twin and triplet crises, as well as the sequencing of financial crises. It finds that banking crises frequently occur together with currency or sovereign debt crises. It also finds that banking crises tend to precede currency and sovereign debt crises. The paper also includes data on the outcomes of banking crises, including output losses, fiscal costs, increases in public debt, and peak nonperforming loans (NPLs). It finds that output losses and increases in public debt tend to be larger in advanced economies. Fiscal costs are larger in developing and emerging economies. The paper also includes data on the costliest banking crises since 1970, showing that recent and ongoing crises feature among the ten costliest crises. The paper concludes that the data show several interesting issues that require further research.This paper updates the widely used banking crises database by Laeven and Valencia (2008, 2010) with new information on recent and ongoing crises, including updated information on policy responses and outcomes (i.e., fiscal costs, output losses, and increases in public debt).
