A financial crisis (also known as a currency crisis ) occurs when the value of a currency changes quickly,undermining its ability to serve as a medium for exchange or a store of value.
A financial crisis is a disruption to financial markets in which adverse selection and moral hazard problems become much worse,so that financial markets are unable to efficiently channel funds to those who have the most productive investment opportunities.As a result,a financial crisis can drive the economy away from an equilibrium with high output in which financial markets perform well to one in which output declines sharply.
