It provides financial services, including issuing money in the form of coins, banknotes or debit cards, receiving deposits of money, lending money and processing transactions. A retail bank accepts deposits from customers and in turn makes loans based on those deposits. Some banks (called Banks of issue) issue banknotes as legal tender. Many retail banks offer ancillary financial services to make additional profit; for example: selling insurance products, investment products or stock broking. A retail bank generates a profit from the differential between what level of interest it pays for deposits and other sources of funds, and what level of interest it charges in its lending activities. This difference is referred to as the spread between the cost of funds and the loan interest rate. Services typically offered by banks Although the basic type of services offered by a retail bank depends upon the type of bank and the country, services provided usually include: Taking deposits from their customers and issuing current and savings accounts to individuals and businesses Extending loans to individuals and businesses Cashing cheques Facilitating money transactions such as wire transfers and cashiers checks Issuing credit cards, ATM cards, and debit cards Storing valuables, particularly in a safe deposit box Cashing and distributing bank rolls Consumer & commercial financial advisory services Need for Business Intelligence and Data Warehouse Summary information to assess performance v/s target and benchmark Discover low performing and high performing areas Discover causes of low / high performance Bringing data together for a single point of truth.
