by Commercial banking is the backbone of the financial system. It refers to banks that accept deposits from the public and provide loans to individuals, businesses, and governments. The main aim is to earn profit while ensuring safety and liquidity of funds. Commercial banks perform key functions such as accepting savings and current deposits, giving credit, facilitating payments, and supporting economic development. In India, commercial banks include public sector banks, private sector banks, and foreign banks, regulated by the Reserve Bank of India. They play an important role in financial inclusion, capital formation, and smooth functioning of trade and industry in the economy.
Features of Commercial Banks:
1. Dealing in Money & Near-Money Assets
Unlike trading or manufacturing firms, a commercial bank’s primary commodity is money. It deals with deposits (liabilities) and loans/investments (assets). Banks also deal in near-money assets like treasury bills, government securities, and commercial papers, which are highly liquid. This feature distinguishes banks from other financial intermediaries. By accepting money on deposit and creating credit, banks effectively increase the money supply in the economy. Their entire profitability depends on the spread between the interest earned on assets and paid on liabilities, making money management their core business.
2. Agency Services & Utility Functions
Commercial banks provide a wide range of agency and general utility services beyond core deposits and loans. Agency services include collecting cheques, drafts, bills of exchange, paying insurance premiums, acting as trustees or executors, and handling periodic payments (electricity, water, taxes). Utility functions include issuing demand drafts, traveler’s cheques, providing lockers, acting as referees for customer creditworthiness, and facilitating foreign exchange. This “one-stop-shop” feature strengthens customer relationships and generates non-interest (fee-based) income, reducing reliance on interest spreads and cushioning banks during periods of falling lending rates.
3. Profit & Service Orientation
Commercial banks operate on dual objectives: profitability and public service, though profit remains the primary motive. They are business enterprises owned by shareholders, not charities. Profit is earned mainly through the interest rate spread (lending rate minus deposit rate) and commissions. However, unlike purely commercial firms, banks also serve critical societal roles such as facilitating payments, supporting trade, and implementing government schemes (e.g., priority sector lending). The challenge lies in balancing profit maximization (e.g., high-risk lending) with prudential norms and social obligations mandated by regulators like the RBI.
4. Creation & Destruction of Credit
A unique feature of commercial banks is their ability to create credit, i.e., expand the money supply beyond the initial deposits received. Through the fractional reserve system (keeping only a fraction of deposits as cash reserves), banks lend out surplus funds. These loans, when spent, become deposits in other banks, allowing further lending. This multiplies purchasing power in the economy. Conversely, banks destroy credit when loans are repaid or defaults occur. This feature makes commercial banks powerful engines of economic growth but also potential sources of inflation or systemic crises if not regulated through Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR).
5. High Liquidity & Safety of Deposits
Commercial bank deposits are highly liquid, meaning customers can withdraw their money on demand (savings/current accounts) or with short notice (fixed deposits). Banks maintain statutory reserves (CRR/SLR) and ensure a portion of their assets are in short-term, easily encashable forms like money market instruments. Additionally, depositor safety is enhanced by regulations (RBI supervision) and deposit insurance (DICGC cover up to ₹5 lakh per depositor in India). This liquidity and safety feature is the bedrock of public confidence; even a rumor of illiquidity can trigger a bank run, highlighting why banks are more conservatively managed than other businesses.
6. Financial Intermediation
Commercial banks act as essential intermediaries between surplus units (depositors with idle funds) and deficit units (borrowers needing capital). They transform deposits into loans by performing three key transformations: size (aggregate small deposits into large loans), maturity (use short-term deposits to fund long-term loans), and risk (diversify credit risk across many borrowers). This intermediation reduces transaction costs for both savers and borrowers, allocates capital efficiently, and reduces information asymmetry. Without this feature, surplus households would struggle to directly lend to corporations, severely hampering economic growth and investment.
7. Acceptance of Demand Deposits
A distinguishing feature of commercial banks (vs. other financial institutions like NBFCs or development banks) is the acceptance of repayable demand deposits. These include current accounts and savings accounts, from which customers can withdraw money anytime without prior notice, using cheques, debit cards, or online transfers. This “demand” nature creates a unique liquidity risk not faced by non-bank lenders. Commercial banks must therefore maintain a higher proportion of liquid assets (cash reserves) than any other financial intermediary. The ability to offer transactional banking services (payments, clearing) makes commercial banks the backbone of a country’s payment and settlement system.
8. Branch Banking & Network Reach
Commercial banks typically operate through a widespread network of branches, ATMs, and digital platforms, often extending to rural and semi-urban areas. This branch-based model (common in India, UK, and Europe) allows banks to mobilize small savings from a large, geographically dispersed population. It also enables last-mile delivery of credit, government subsidies (Direct Benefit Transfer), and financial inclusion schemes. Unlike unit banking (USA traditionally), branch banking allows risk diversification across regions and pooling of funds from surplus to deficit areas. The extensive network gives commercial banks unparalleled data on local economic activity, aiding better credit assessment and cross-selling of insurance/pension products.
Functions of Commercial Banks:
1. Acceptance of Deposits
This is the primary and oldest function of commercial banks. Banks accept various types of deposits from the public—savings accounts (for individuals), current accounts (for businesses with cheque facilities), and fixed/term deposits (for higher interest with lock-in periods). These deposits are repayable on demand or after a specified maturity. By mobilizing small, scattered savings from households and firms, banks pool large financial resources. Depositors earn interest (except in current accounts) while having safety, liquidity, and sometimes cheque-writing ability. This function transforms idle money into active capital, forming the base for all other banking activities and credit creation.
2. Granting Loans and Advances
After keeping a portion of deposits as reserves (CRR/SLR), banks lend the surplus to borrowers seeking funds for business, agriculture, housing, or personal needs. Loans are given against security (collateral) and bear interest, which is the main source of bank income. Forms of lending include cash credit (withdrawal up to a limit), overdraft (drawing beyond account balance), term loans (fixed tenure), and bill discounting (advance against trade bills). Banks assess creditworthiness through the 5 Cs (Character, Capacity, Capital, Collateral, Conditions). This function fuels economic growth, but also carries credit risk, requiring prudent lending policies and diversification.
3. Credit Creation
A unique function of commercial banks is their ability to create credit, i.e., generate deposits and money supply beyond the initial cash received. When a bank grants a loan, it does not typically give cash; instead, it opens a deposit account in the borrower’s name. This new deposit is “created money.” The borrower spends it; the recipient deposits it in another bank, which then lends further. Through the fractional reserve system (only a fraction of deposits held as cash), this process multiplies the original deposit. For example, with a 20% reserve ratio, ₹100 deposits can create ₹500 total deposits. However, credit creation is limited by CRR, SLR, and loan demand.
4. Agency Functions
Commercial banks act as agents on behalf of their customers, earning fee-based income. Agency functions include: (a) collecting cheques, drafts, bills, and interest/dividend on securities; (b) making periodic payments like insurance premiums, rent, taxes, and utility bills; (c) acting as trustees, executors, or attorneys; (d) purchasing and selling securities on customer instructions; and (e) remitting funds through demand drafts, mail/telegraphic transfers, and online transfers. These services do not involve banks’ own money but build customer loyalty and convenience. In India, agency functions also include collection of income tax, GST, and subscription amounts for government bonds or IPOs.
5. General Utility Functions
Beyond agency services, banks provide miscellaneous utility functions that facilitate commerce and daily life. These include: issuing letters of credit (guaranteeing payment in trade), traveler’s cheques and forex cards; providing safe deposit lockers (vaults for valuables); acting as referees for customer creditworthiness; underwriting government securities and shares; and facilitating e-banking, mobile banking, and ATM services. Banks also assist in foreign exchange transactions, merchant banking, and leasing. These functions generate non-interest income (commissions, fees, service charges), helping banks remain profitable even when interest spreads are narrow. They also enhance financial inclusion by reaching underserved populations.
6. Collection and Payment of Cheques
A core clearing and settlement function of commercial banks is the collection of cheques drawn on other banks and payment of cheques drawn on themselves. Banks act as members of the clearing house (managed by RBI or an authorized entity). When a customer deposits a cheque payable elsewhere, the bank presents it to the drawee bank through the clearing system, collects the amount, and credits the customer’s account. Conversely, when a customer issues a cheque, the bank debits the account and pays the holder or their bank. Modern systems like CTS (Cheque Truncation System) enable image-based clearing, reducing time and fraud risk. This function underpins the entire payment system of an economy.
7. Acting as Issuer of Demand Drafts & Banker’s Cheques
For safe and guaranteed fund transfer, banks issue demand drafts (DDs) and banker’s cheques (pay orders, typically for local use). A DD is a pre-paid negotiable instrument drawn by one branch of a bank on another branch (or another bank’s correspondent), instructing payment to a specified payee. Since the amount is debited upfront from the purchaser, DDs carry no risk of dishonor due to insufficient funds (unlike personal cheques). Banks charge a commission for this service. This function is critical for students paying fees, tender deposits in government contracts, traders making advance payments, and immigrants remitting money. With NEFT/RTGS/IMPS gaining popularity, DDs now primarily serve non-digital or legal/statutory requirements.
8. Foreign Exchange Business
Commercial banks authorized by the central bank (AD Category I banks in India) deal in foreign exchange. They buy and sell foreign currencies (USD, EUR, GBP, JPY, etc.), issue foreign traveler’s cheques and prepaid forex cards, facilitate outward and inward remittances, and finance foreign trade through export-import (Exim) instruments like letters of credit (LCs), bills of exchange, and packing credit. Banks also hedge currency risk for corporate clients using derivatives like forward contracts, options, and swaps. This function is essential for globalization; without it, cross-border trade and investment would be impossible. Banks maintain nostro (our account with foreign bank) and vostro (their account with us) accounts to settle international transactions.
Types of Commercial Banks:
1. Public Sector Banks (PSBs)
Public Sector Banks are those where the majority stake (more than 50%) is held by the Government of India. They are governed by the Banking Companies (Acquisition and Transfer of Undertakings) Acts. These banks dominate Indian banking in terms of branch network, especially in rural and semi-urban areas. They play a crucial role in implementing government schemes like financial inclusion, priority sector lending, and Direct Benefit Transfer (DBT). Examples include State Bank of India, Bank of Baroda, and Punjab National Bank. Following recent mergers, the number of PSBs has been reduced to 12. Their performance is closely monitored by the Ministry of Finance and the RBI.
2. Private Sector Banks
Private Sector Banks are those where the majority stake and control are held by private individuals, corporations, or trusts, not the government. They are registered under the Companies Act and licensed by the RBI. These banks are known for superior customer service, aggressive technology adoption (internet/mobile banking), and innovative product offerings. They operate with greater operational efficiency and profitability but have a relatively lower rural presence compared to PSBs. Examples include HDFC Bank, ICICI Bank, Axis Bank, and Kotak Mahindra Bank. They are further categorized into old private banks (e.g., City Union Bank) and new generation banks (post-1990s liberalization).
3. Foreign Banks
Foreign Banks are incorporated outside India but operate branches or subsidiaries within India after obtaining a license from the RBI. They bring global best practices, advanced risk management models, and sophisticated treasury operations. Their focus is primarily on high-end corporate clients, trade finance, foreign exchange, and wealth management for affluent individuals. They have limited retail presence and rural reach due to regulatory restrictions. Examples include HSBC, Citibank (now Axis retail sold), Standard Chartered, and Deutsche Bank. Foreign banks are subject to stricter regulatory requirements regarding capital adequacy and exposure limits compared to domestic banks.
4. Regional Rural Banks (RRBs)
Regional Rural Banks were established under the RRB Act, 1976, to cater specifically to rural and agricultural finance needs. They are jointly owned by the Central Government (50%), State Government (15%), and a Sponsor Public Sector Bank (35%). RRBs operate at the district level and focus exclusively on small and marginal farmers, landless laborers, artisans, and rural micro-enterprises. They provide short-term crop loans, Kisan Credit Cards (KCC), and other priority sector advances at concessional rates. Examples include Punjab Gramin Bank, Baroda UP Bank, and Saurashtra Gramin Bank. RRBs have a single branch per specified region and offer limited products compared to commercial banks.
5. Co-operative Banks
Cooperative Banks are financial institutions registered under the Cooperative Societies Act, operating on the principle of “mutual help.” They are distinguished from commercial banks by their cooperative structure (members are both owners and customers). In India, they operate at three levels: Primary Agricultural Credit Societies (PACS) at village level, District Central Cooperative Banks (DCCBs) at district level, and State Cooperative Banks (StCBs) at state level. Cooperative banks primarily fund agriculture, small-scale industries, and local trade. However, they are regulated by dual authorities—RBI (banking aspects) and Registrar of Cooperative Societies (management aspects). Examples include Saraswat Cooperative Bank and Punjab & Maharashtra Cooperative (PMC) Bank.
6. Small Finance Banks (SFBs)
Small Finance Banks are a category of niche banks introduced by the RBI in 2014 to further financial inclusion. They are licensed under Section 22 of the Banking Regulation Act and are scheduled banks. SFBs primarily serve unserved and underserved segments—small farmers, micro enterprises, street vendors, and low-income households. They are required to lend at least 75% of their Adjusted Net Bank Credit (ANBC) to priority sectors and 50% to small and marginal borrowers. Unlike payment banks, SFBs can accept all types of deposits and lend. Examples include Ujjivan Small Finance Bank, Equitas Small Finance Bank, and AU Small Finance Bank (converted to universal bank).
7. Payment Banks
Payment Banks are a differentiated bank model introduced by the RBI on the recommendation of the Nachiket Mor Committee (2014). They can accept only demand deposits (savings and current accounts), up to a maximum limit of ₹2 lakh per customer. They cannot issue loans or credit cards. Their primary functions include digital payments, remittances, mobile banking, ATM services, and selling third-party financial products (insurance, mutual funds). Payment banks aim to convert cash-heavy informal households into digital banking users. Examples include Airtel Payments Bank, India Post Payments Bank (IPPB), Paytm Payments Bank, and NSDL Payments Bank. They operate on a low-cost, high-volume, branch-light model.
Role of Commercial Banks in Economy:
1. Financial Intermediation
Commercial banks act as intermediaries between savers and borrowers. They collect deposits from individuals and institutions and provide loans to businesses and consumers. This process ensures proper utilization of idle funds and promotes investment. By channelizing savings into productive activities, banks support economic growth. In India, banks operate under the supervision of the Reserve Bank of India, which ensures stability and efficient functioning of this intermediation process.
2. Credit Creation
Commercial banks have the power to create credit by lending more than their actual reserves. When banks provide loans, new deposits are created in the economy. This increases money supply and boosts economic activities like production, trade, and consumption. Credit creation plays a vital role in accelerating economic development, especially in developing countries like India.
3. Facilitating Trade and Commerce
Banks provide various services such as letters of credit, bank guarantees, and payment systems that support domestic and international trade. These services reduce risk and increase trust between buyers and sellers. By ensuring smooth financial transactions, commercial banks help in the expansion of trade and business activities.
4. Promotion of Savings and Investment
Commercial banks encourage people to save money by offering different deposit schemes like savings accounts, fixed deposits, and recurring deposits. These savings are then invested in productive sectors of the economy. This leads to capital formation, which is essential for economic development.
5. Economic Development and Growth
Banks provide financial support to key sectors like agriculture, industry, and infrastructure. By offering loans and credit facilities, they help in employment generation and industrial growth. Commercial banks also support government policies and development programs, contributing to overall economic progress.
