This article reviews the European Systematic Risk Board (ESRB), its role, approach, outputs, and effects in the European Union. The ESRB is the reason for macroprudential oversight of financial systems. Macroprudential policy is used to identify and reduce financial risks and limit financial imbalances. This policy is for both upturns and downturns of economic cycles. The role of the ESRB should be further enhanced to cover the entire financial system and institutions.
