This paper updates and expands the database on systemic banking crises presented in Laeven and Valencia (IMF Econ Rev 61(2):225–270, 2013a). The database draws on 151 systemic banking crisis episodes around the globe during 1970–2017 to include information on crisis dates, policy responses to resolve banking crises, and their fiscal and output costs. We provide new evidence that crises in high-income countries tend to last longer and be associated with higher output losses, lower fiscal costs, and more extensive use of bank guarantees and expansionary macro-policies than crises in low- and middle-income countries. We complement the banking crisis dates with sovereign debt and currency crises dates to find that sovereign debt and currency crises tend to coincide with or follow banking crises.
