1. What Is a Bank and What Does It Do?
A bank is a financial intermediary that accepts deposits and channels those deposits into lending activities, directly impacting the economy. Banks are essential components of the financial system. They play a crucial role in facilitating economic activity by providing a safe place to store money, offering loans, and enabling payments.
1.1. Core Functions of a Bank
Banks primarily serve as intermediaries between savers and borrowers. They accept deposits from individuals and businesses, providing a safe and convenient way to store funds. These deposits are then used to make loans to individuals, businesses, and governments. This process of maturity transformation—converting short-term deposits into longer-term loans—is a key function of banks.
1.2. The Role of Banks in the Economy
Banks are vital to the financial health of any economy. They facilitate the flow of money, support investment, and promote economic growth. Without banks, it would be difficult for businesses to access the capital they need to expand, for individuals to purchase homes, and for governments to finance public projects.
1.3. Key Services Provided by Banks
Banks offer a range of services to their customers, including:
- Checking and savings accounts
- Loans (mortgages, auto loans, business loans)
- Credit cards
- Investment services
- Financial advice
1.4. The Importance of Trust in Banking
The banking system relies heavily on trust. Depositors need to trust that their money is safe, and borrowers need to trust that they can repay their loans. This trust is maintained through regulation, insurance, and sound banking practices. As Jeanne Gobat notes in Finance & Development, “Essentially, banking is about confidence or trust—the belief that the bank has the money to honor its obligations.”

2. What Are the Primary Functions of a Bank?
Banks perform several critical functions that support economic stability and growth, acting as linchpins in the financial ecosystem. Their services range from safeguarding deposits to facilitating payments and extending credit.
2.1. Accepting Deposits
Accepting deposits is one of the most fundamental functions of a bank. Banks provide a safe and convenient place for individuals and businesses to store their money. Deposits can be in the form of checking accounts, savings accounts, or time deposits.
2.2. Granting Loans
Banks use the deposits they collect to make loans to individuals, businesses, and governments. These loans can be used for a variety of purposes, such as purchasing a home, starting a business, or financing a public project. The ability to provide credit is essential for economic growth.
2.3. Facilitating Payments
Banks play a crucial role in the payments system, processing transactions ranging from small personal checks to large electronic transfers between institutions. They ensure that funds are transferred efficiently and securely. This includes services like:
- Processing checks
- Electronic funds transfers
- Credit and debit card transactions
2.4. Managing Risk
Banks are experts in managing risk. They assess the creditworthiness of borrowers, diversify their loan portfolios, and maintain adequate capital reserves to absorb potential losses. Effective risk management is essential for maintaining the stability of the banking system.
2.5. Providing Financial Advice
Many banks offer financial advice to their customers, helping them make informed decisions about their money. This can include advice on investments, retirement planning, and estate planning.
2.6. Creating Money
Banks create money through the process of lending. When a bank makes a loan, it creates a new deposit in the borrower’s account. This new deposit increases the money supply. The process is magnified through the multiplier effect.

3. How Do Banks Generate Revenue and Profits?
Banks generate revenue through a variety of channels, including interest income, fees, and trading activities, all contributing to their overall profitability. Understanding these revenue streams is crucial for evaluating a bank’s financial performance.
3.1. Interest Income
The primary source of revenue for most banks is interest income. This is the difference between the interest they earn on loans and securities and the interest they pay on deposits and borrowings. The spread between these rates is a key indicator of a bank’s profitability.
3.2. Fees for Services
Banks also generate revenue from fees for various services, such as:
- Checking account fees
- ATM fees
- Overdraft fees
- Loan origination fees
- Investment banking fees
- Advisory services
3.3. Trading Income
Some banks engage in trading activities, buying and selling securities for their own account. This can generate significant revenue, but it also involves considerable risk. Trading income can come from:
- Fixed income trading
- Equity trading
- Currency trading
- Commodities trading
3.4. Investment Banking
Investment banking activities, such as underwriting securities and providing advisory services for mergers and acquisitions, can be a significant source of revenue for larger banks. Investment banking includes:
- Underwriting new securities
- Advisory services for M&A
- Private equity
- Hedge fund management
3.5. Return on Assets (ROA)
Banks typically earn between 1% and 2% of their assets. This is commonly referred to as a bank’s return on assets (ROA). ROA is a key metric for evaluating a bank’s profitability.

Banks are the backbone of the financial system, providing essential services that support economic stability and growth, helping to maintain a healthy and efficient economy.
4.1. Facilitating Economic Activity
Banks facilitate economic activity by providing a safe place to store money, offering loans, and enabling payments. They connect savers and borrowers, channeling funds to productive uses.

5. How Do Banks Create Money?
Banks create money through lending, which expands the money supply in an economy, impacting inflation and overall economic health.
5.1. The Lending Process
When a bank makes a loan, it creates a new deposit in the borrower’s account. This new deposit increases the money supply. The borrower can then use this money to make purchases, which in turn creates new deposits in other banks.
5.2. Reserve Requirements
Banks are required to hold a certain percentage of their deposits in reserve, either in cash or in securities that can be quickly converted to cash. This reserve requirement limits the amount of money that banks can lend.
5.3. The Money Multiplier
The money multiplier is the amount of money that the banking system can create from an initial deposit. The size of the multiplier depends on the reserve requirement. For example, if the reserve requirement is 10%, a bank can lend out 90% of each deposit. This process can repeat itself multiple times, creating a multiplier effect.
5.4. Impact on the Economy
The creation of money by banks has a significant impact on the economy. It can stimulate economic growth by increasing the amount of money available for investment and consumption. However, it can also lead to inflation if the money supply grows too rapidly.
