How Banks Earn Money: An Inside Look at the Lending Business Model

Commercial banks earn their profit through the interest they charge on loans and the interest they pay on deposits. While this concept might seem straightforward, it is a complex process that involves various financial mechanisms and regulations.

Understanding the Basics of Interest and Loans

When customers open savings accounts or fixed deposits (FDs) in a bank, they are essentially lending their money to the bank. In return, the bank pays them interest on this deposited money. This mechanism is crucial for the bank to earn profits. However, the brilliance of the banking system lies in the way they use this money to make even more money.

Letrsquo;s take an example to illustrate this. If you deposit Rs. 100 in a bank at an interest rate of 10%, the bank will pay you Rs. 10 as interest annually. Now, the bank takes Rs. 90 of your deposit and lends it out at a higher interest rate. Assume that the bank lends out this Rs. 90 at an interest rate of 20%. In this case, the bank will charge Rs. 18 (20% of 90) as interest each year. Out of this, the bank will still have to pay you Rs. 10 as interest. The difference, Rs. 8, is their profit for that year.

Itrsquo;s important to note that this is a simplified example. The actual lending and deposit rates can vary widely based on various factors including market conditions, regulatory requirements, and the bankrsquo;s risk policies.

The Two Main Functions of Commercial Banks

The two main functions of commercial banks are to receive deposits and to lend money. This is their core business model. The bank pays interest on deposits, acting as a buyer of credit, while it charges interest on loans, acting as a seller of credit.

Compared to the interest rate paid on deposits, the interest rate charged on loans is usually much higher. This is the primary source of a bankrsquo;s profit. The bank can only lend a certain amount of money that is a fraction of its total deposits. Typically, commercial banks are regulated to lend no more than 2/3 of their depositorsrsquo; money. The remaining 1/3 is kept as cash and securities, which earn the bank some interest or income. This mechanism ensures that the bank has the necessary liquidity to meet withdrawal demands from depositors.

Additional Sources of Revenue

Banking is not just about deposits and loans. Banks earn additional income from various other services. These services include:

Bill collections: Banks often collect bills on behalf of their clients, earning a commission for this service. DD (Demand Draft) issuance: Banks provide DD services, which are similar to a check but more secure, and charge a fee for this. Guarantees: When a bank guarantees payment or performance, it charges a fee for this service. Letter of Credit (LC): Banks issue LCs to ensure that payments will be made to a seller under certain conditions, charging a fee for this service. Safe deposit vault: Banks offer safe deposit vault services for customers to store valuables, generating additional income through fees.

All these services contribute to the bankrsquo;s overall earnings, making banking a complex but highly profitable business venture.

Conclusion

The earning model of banks is a carefully balanced act of finance. By understanding how banks earn money from both deposits and loans, as well as additional services, one can appreciate the complexity of the financial system and the role that banks play in it. While the simplified example of borrowing and lending can be misleading, the actual business model is much more intricate and involves a wide array of financial and regulatory considerations.
