Banking is a core function of the financial services industry, so it only makes sense that banks are among the leading employers within the financial field.Before you begin looking for a job in banking, it's important to know what types of jobs are available and the qualifications you'll need. You should also understand the distinction between commercial banking and retail banking. Retail banks are those that serve families and small businesses. Commercial banks provide services to larger businesses and corporations.

It all ties back to the fundamental way banks make money: Banks use depositors' money to make loans. The amount of interest the banks collect on the loans is greater than the amount of interest they pay to customers with savings accounts—and the difference is the banks' profit.

Banks play a major role in all the economic and financial activities in modern society. They are playing key role in activities financing the industries. Banks promote both these activities; they mobilize small deposits from the public and provide financial resource to big industries.

Today, banks have diversified their activities and are getting into new products and services that include opportunities in credit cards, consumer finance, wealth management, life and general insurance, investment banking, mutual funds, pension fund regulation, stock broking services, custodian services, private equity, etc. Further, most of the leading Indian banks are going global, setting up offices in foreign countries, by themselves or through their subsidiaries.
