Introduction
Banks are the backbone of the modern financial system and play a pivotal role in the economic development of a country. A bank is not merely a financial institution that accepts deposits and grants loans, but also an essential component of the economic structure that facilitates trade, investment, and development. It serves as a link between people who have surplus funds (savers) and those who need funds (borrowers), thus ensuring efficient allocation of financial resources.
In today’s globalized and technology-driven world, modern commercial banks have evolved beyond traditional banking. They now offer a wide range of financial services, including digital banking, investment management, insurance, credit creation, and financial advisory.
This article aims to explain in detail the meaning of a bank, its evolution, and the various functions of modern commercial banks, covering both traditional and innovative roles in economic growth.
1. Definition of a Bank
A bank is a financial institution that deals in money. It accepts deposits from the public, provides loans and advances, and offers various financial services such as payment systems, fund transfers, and investment opportunities.
In simple terms, a bank acts as a financial intermediary between depositors and borrowers.
1.1 Legal Definition
According to the Banking Regulation Act, 1949 (India):
“Banking means the accepting, for the purpose of lending or investment, of deposits of money from the public, repayable on demand or otherwise, and withdrawable by cheque, draft, order or otherwise.”
Thus, a bank is any institution that performs the act of banking as defined by law.
1.2 Economic Definition
Economically, a bank is a financial enterprise that mobilizes idle funds from individuals and institutions and channels them into productive uses by lending to businesses, industries, and individuals.
1.3 Features of a Bank
- Accepts deposits from the public.
- Provides loans and advances.
- Operates payment and settlement systems.
- Deals in credit creation.
- Functions under the supervision of the central bank (e.g., RBI in India).
- Acts as a trustee, agent, and financial advisor.
2. Types of Banks
Before understanding the specific functions of modern commercial banks, it is important to classify banks based on their nature and functions.
- Commercial Banks: Deal with general public and business firms; aim to earn profit through lending and investments.
- Cooperative Banks: Operate on cooperative principles to provide affordable credit to members.
- Central Bank: The apex monetary authority that controls the money supply and regulates the banking system (e.g., Reserve Bank of India).
- Development Banks: Provide long-term finance to industrial and agricultural sectors.
- Investment Banks: Assist in raising capital, mergers, and financial advisory.
- Regional Rural Banks (RRBs): Serve rural areas with credit and financial services.
- Microfinance Institutions: Provide small loans to low-income groups and entrepreneurs.
Among all these, commercial banks form the foundation of modern financial systems and are the main focus of this discussion.
3. Meaning of a Commercial Bank
A commercial bank is a profit-oriented financial institution that accepts deposits from the public and provides loans and advances to individuals and enterprises to earn interest income.
Commercial banks perform a wide range of functions beyond lending and deposits — including investment services, trade financing, and promoting digital financial inclusion.
3.1 Classification of Commercial Banks
- Public Sector Banks: Owned and managed by the government (e.g., SBI, PNB).
- Private Sector Banks: Owned by private shareholders (e.g., HDFC Bank, ICICI Bank).
- Foreign Banks: Operate in the country but are headquartered abroad (e.g., Citibank, HSBC).
- Regional Rural Banks (RRBs): Operate regionally to promote rural finance.
4. Functions of Modern Commercial Banks
Modern commercial banks perform a wide variety of functions that can be broadly classified into the following categories:
A. Primary Functions
B. Secondary Functions
C. Modern and Innovative Functions
A. Primary Functions of Commercial Banks
1. Accepting Deposits
The most fundamental function of a bank is to accept deposits from the public, ensuring safety and liquidity. Banks mobilize savings and make them available for productive purposes.
Types of Deposits:
- Current Deposits (Demand Deposits):
- Depositors can withdraw money anytime using cheques.
- No interest is paid.
- Used mainly by businessmen and firms.
- Savings Deposits:
- Suitable for individuals to save a part of their income.
- Limited withdrawals allowed.
- Interest is paid at a moderate rate.
- Fixed Deposits (Time Deposits):
- Deposits are made for a fixed term (e.g., 6 months, 1 year, 5 years).
- Higher rate of interest offered.
- Cannot be withdrawn before maturity.
- Recurring Deposits:
- Depositors deposit a fixed amount every month for a fixed period.
- Encourages regular savings.
By mobilizing these deposits, banks convert idle funds into productive capital.
2. Granting Loans and Advances
The second major function of a commercial bank is to provide loans and advances to individuals, traders, and industries to promote economic activity.
Types of Loans:
- Short-term Loans: For working capital and immediate needs.
- Medium-term Loans: For business expansion or equipment purchase.
- Long-term Loans: For industrial or infrastructure projects.
Forms of Advances:
- Overdraft: Facility to withdraw more money than the balance in account.
- Cash Credit: Credit granted against security or inventory.
- Bills Discounting: Banks purchase bills of exchange before maturity at a discount.
- Term Loans: Fixed amount granted for a fixed period.
Loans and advances are the primary source of income for commercial banks through interest and service charges.
3. Credit Creation
One of the most important functions of commercial banks is credit creation. Banks create credit by lending more money than the actual cash reserves they hold.
When banks grant loans, they do not pay cash but open a deposit account in the borrower’s name. This increases total deposits in the banking system, effectively multiplying the money supply.
Process of Credit Creation:
- Bank receives deposits → keeps a part as reserve → lends the rest.
- The loaned amount becomes a new deposit in another bank.
- The process repeats, creating multiple deposits from the same initial money.
Thus, commercial banks play a crucial role in expanding money supply and supporting economic activity.
4. Investment of Funds
Commercial banks invest a part of their deposits in:
- Government securities (bonds, treasury bills)
- Corporate shares and debentures
- Other financial instruments
These investments provide stability and liquidity to banks while earning safe returns.
B. Secondary Functions of Commercial Banks
In addition to primary functions, commercial banks perform several secondary functions to facilitate trade, business, and economic development.
