How Banks Make Money
Commercial banks serve as critical intermediaries in financial services, including money transfers, loans, and investments. Adequate production of profit is crucial to their functioning and development. undefined

Interest Income
Loans and Mortgages:
Most banks' greatest source of revenue is the interest they receive from loans and mortgages. Banks borrow money from depositors at a lower interest rate and give it to individuals, businesses, and governments at a higher interest rate. The net interest margin refers to the amount of interest earned from borrowers less the amount paid to depositors. This is an important source of income for banks.

Credit Cards:

Banks offer credit cards and applicable interest rates for these balances. Credit card interest rates are generally higher than other types of credit, giving banks significant revenues. Also, banks may charge annual fees for credit card usage.

Fee-Based Income
Account Fees:
Some of the fees that banks impose for checking and savings accounts include monthly maintenance fees, overdraft fees, and charges for bounced checks. Even though some banks have no-fee accounts that attract many customers, many rely on these fees as steady income sources.

Service Fees:
This income can be in the form of fees charged for other services such as wire transfers, cashier's checks, and foreign exchange. These are charged on individual and business accounts and they form part of the income of the bank.

Investment Services:
Banks provide wealth management and investment services. They earn commissions on managing portfolios, giving advice and sourcing for stocks among others. These fees may be a fixed percentage of the assets managed or a fee based on the volume of transactions.

Trading and Investment Income
Securities Trading:
Banks deal in securities such as stocks, bonds, and derivatives to realize profits. There is also information that proprietary trading, where a bank trades its own money, can generate substantial profits despite the increased risk.

Investment Banking:
In investment banking, these services include underwriting of new debt and equity sales, mergers and acquisitions, and advisory services. These activities, which include charging hefty fees, form a significant source of income for many banks.

Interest from Investments:
Banks trade in securities such as government securities and corporate securities, among others. The interest and dividends arising from such investments form part of their income.

Ancillary Services
Insurance Products:
Some banks also offer insurance services such as life, health, and property insurance. They receive a certain percentage of the policies sold, which is an additional source of income for them.

Merchant Services:
Banks provide businesses with merchant services, for which these businesses pay the banks for the provision of credit card and electronic payment services. These services are important for businesses and give banks a steady revenue stream.
