Commercial Banks in India: Types, Structure, Functions

Every salary credit, every EMI debit, every UPI transfer between friends splitting a dinner bill — all of it runs through commercial banks, the single most visible layer of India’s financial system. Yet most people who use these banks daily couldn’t clearly explain what actually distinguishes a public sector bank from a private one, or why some banks feel dramatically different to deal with than others. As of 2026, India counts 12 public sector banks, 21 private sector banks, and 44 foreign banks operating under RBI’s commercial banking framework, alongside regional rural banks extending that reach into agricultural India. Here’s a complete, clear breakdown of how the system is structured and what it actually does.

What Defines a Commercial Bank

Before breaking down the types, it’s worth being precise about what actually makes a bank “commercial,” since this distinguishes it from cooperative and development banks covered under separate frameworks entirely.

• A commercial bank is a profit-oriented financial institution that accepts deposits, extends loans, and offers a broad range of financial services
• Unlike cooperative or development banks with specific social or developmental mandates, commercial banks operate primarily to earn profit while maintaining financial stability
• Governed by the Banking Regulation Act, 1949, and supervised directly by the Reserve Bank of India
• Functions as an intermediary bridging savers and borrowers, mobilising idle savings into productive economic use

Scheduled vs Non-Scheduled Commercial Banks

This classification determines what regulatory privileges and obligations a commercial bank actually has, and it’s the most fundamental split in the entire structure.

• Scheduled Commercial Banks are listed in the Second Schedule of the RBI Act, 1934, and meet specific capital and reserve requirements
• Scheduled status grants eligibility for RBI facilities including borrowing funds and participating in the clearinghouse system
• Scheduled banks must maintain a Cash Reserve Ratio with the RBI and submit periodic compliance reports
• The vast majority of commercial banks operating in India today fall under the Scheduled category, with non-scheduled banks representing a smaller, less regulated, and generally riskier segment

Public Sector Banks

Public sector banks are majority government-owned, and they remain the single largest category by both branch network and total assets in Indian commercial banking.

• Include State Bank of India and 12 nationalised banks such as Punjab National Bank, Bank of Baroda, and Canara Bank
• Trace their modern structure back to the 1969 nationalisation of 14 major commercial banks, with a further wave in 1980
• Account for a significant majority of India’s total banking assets, despite facing historical challenges around non-performing assets and governance
• Play a central role in government financial schemes, priority sector lending, and rural banking reach

Private Sector Banks

Private sector banks operate with private shareholder ownership, and their post-1991 emergence fundamentally reshaped Indian banking competition.

• Include institutions like HDFC Bank, ICICI Bank, Axis Bank, and Kotak Mahindra Bank
• Only licensed again after India’s early-1990s market liberalisation ended decades of nationalised-only banking
• Generally distinguished by stronger technology adoption, faster service delivery, and more aggressive digital banking investment
• Currently number 21 institutions, competing directly with public sector banks for retail and corporate customers alike

Foreign Banks

Foreign banks are institutions headquartered outside India but operating branches or subsidiaries within the country under RBI licence.

• 44 foreign banks currently operate in India, spanning branches from institutions like HSBC, Standard Chartered, and Citibank
• Have seen rapid growth in numbers since the 1991 liberalisation opened India’s banking sector to increased foreign participation
• Often serve multinational corporations, institutional clients, and high-net-worth retail customers rather than mass-market retail banking
• Many have increasingly focused on corporate and institutional banking over broad retail presence in recent years

Regional Rural Banks

Regional Rural Banks occupy a distinct niche within the commercial banking structure, established with the specific objective of extending credit to agriculture and rural economic activity.

• Sponsored by public sector banks, which hold majority ownership stakes in each RRB
• Currently number 28 institutions following extensive government-led consolidation under the “One State, One RRB” policy
• Focus specifically on serving farmers, rural artisans, and small businesses across agricultural regions
• Combine commercial banking structure with a deliberately rural-focused operational mandate distinct from mainstream commercial banks

Primary Functions of Commercial Banks

Regardless of category, every commercial bank performs a common core set of functions that keep the broader economy and payment system running.

• Accepting deposits from the public across savings accounts, current accounts, fixed deposits, recurring deposits, and NRI deposit schemes
• Lending money for personal loans, housing loans, vehicle loans, and business financing needs
• Providing overdraft facilities, particularly linked to credit cards and specific banking schemes
• Issuing debit cards, credit cards, and prepaid instruments for everyday transactions

Secondary and Agency Functions

Beyond core deposit-and-loan activity, commercial banks perform a wide range of additional services that extend their role well beyond basic banking.

• Issuing letters of credit and bank guarantees, essential for business and trade transactions
• Collecting payments through cheques and other financial instruments on behalf of customers
• Facilitating the sale and purchase of shares and debentures for investment customers
• Acting as investment banking intermediaries for private companies pursuing Initial Public Offerings
• Providing modern digital services including internet banking, mobile banking, and digital wallet integration

Frequently Asked Questions

Q1. What’s the main difference between public and private sector commercial banks?

Public sector banks are majority government-owned with a legacy dating back to 1969 nationalisation, while private sector banks are privately owned and generally emphasise faster technology adoption and digital service delivery.

Q2. Are foreign banks in India subject to the same regulations as domestic commercial banks?

Yes, foreign banks operating in India are regulated under the Banking Regulation Act and supervised by the RBI, though they often focus more on corporate and institutional banking than mass retail services.

Q3. Why do Regional Rural Banks exist separately from regular commercial banks?

RRBs were specifically created to extend credit and banking services to agricultural and rural communities, a mandate distinct enough from urban commercial banking that a dedicated structure, sponsored by public sector banks, made more sense.

Q4. How can I check if my bank qualifies as a Scheduled Commercial Bank?

Nearly all major public sector, private sector, and foreign banks operating in India today are Scheduled Commercial Banks; you can verify this status through the RBI’s officially published list of scheduled banks.
