Financial Crisis in general and banking crises, in particular, are an ever-present phenomenon across the globe, including developed and developing economies. This paper presents a typology of the financial crisis, which includes debt crisis, terms of trade crisis, exchange rate crisis and finally banking crisis. It provides different criteria to measure unusual volatilities from the crisis for all types of crisis. Specifically, a definition of the banking crisis is mentioned. Based on these definitions the interrelation between various crisis is investigated. In particular, based on empirical data, this paper reports prevalence of banking crisis in different countries at a different time span. Then consequences of the banking crisis are argued and different estimation of the cost of the banking crisis in terms of output loss, fiscal cost and public debt in different countries is reviewed. The database used for this analysis is provided by IMF, which contains a history of the financial crisis for 164 countries from 1970 up to 2012. Then, a mechanism of transmission of a financial crisis from the banking sector to the real sector is explained. At the end, policy recommendation to reduce the probability of banking crisis is provided.
