The Finnish Banking Crisis of 1990s was a deep systemic crisis of the entire Finnish financial sector that took place mainly in the years 1991–1993, after several years of debt-based economic boom in the late 1980s. Its total taxpayer cost was roughly 8% of the Finnish GNP, making it the most severe of the contemporary Nordic banking crises. The crisis has been attributed to a combination of macro-economic turbulence, weak regulation, and bank-specific problems.[1] Governmental intervention included bank takeovers, direct monetary assistance and temporary blanket guarantees to the banks.[2]
