The role of banking
The role of banking system can be compared to the circulatory system within the human body. Just like blood vessels carry essential nutrients to all the parts of the human body, the banking system is expected to supply "money capital" to the all individuals and the institutions.
Role of Capital in the economy is like that of the blood in the human body. As the blood carries the required nutrients to the individual cell, capital promotes productivity in the economic system.
Any disorder in the circulatory system leads to disease in the entire body. Similarly, a flawed capital creation and distribution system has an equally debilitating effect on the economic system.
