Indian Banking System and Structure
The Indian banking system is one of the largest and most complex in the world, serving the financial needs of over 1.4 billion people through a network of commercial banks, regional rural banks, cooperative banks, and microfinance institutions. For candidates appearing for the IBPS Clerk examination, a thorough understanding of the Indian banking system’s structure, its various categories, the Reserve Bank of India’s role, and the key institutions governing the sector is absolutely essential. Questions on the banking system — its organization, types of banks, recent reforms, and regulatory framework — feature regularly in the General Awareness section of the IBPS Clerk examination.
Overview of the Indian Banking System
India’s banking system is broadly classified into five main categories:
- Scheduled Commercial Banks (SCBs)
- Unscheduled Banks
- Regional Rural Banks (RRBs)
- Cooperative Banks
- Small Finance Banks and Payment Banks
Scheduled Commercial Banks are banks included in the Second Schedule of the Reserve Bank of India Act, 1934. They must have a paid-up capital and reserves of at least ₹5 lakh and must satisfy the RBI that their affairs are not conducted to the detriment of the public interest. SCBs form the backbone of India’s banking system.
Categories of Scheduled Commercial Banks
Public Sector Banks (PSBs)
Public Sector Banks are banks in which the government (central and/or state) holds a majority stake (more than 50% of equity). These banks account for the largest share of India’s banking assets and have the most extensive branch network, particularly in rural and semi-urban areas where private banks have been reluctant to expand.
Major Public Sector Banks:
- State Bank of India (SBI): The largest bank in India by assets and market share. Originally established as the Imperial Bank of India in 1870, it was renamed State Bank of India in 1955 after the Government of India acquired a majority stake. SBI has the widest domestic network — over 22,000 branches and 65,000+ ATMs in India, plus international operations in numerous countries. SBI is the banker to the Indian government (manages government accounts, tax payments, and public debt).
- Associate Banks of SBI: Previously, SBI had five associate banks — State Bank of Bikaner and Jaipur (SBBJ), State Bank of Mysore (SBM), State Bank of Patiala (SBP), State Bank of Travancore (SBT), and State Bank of Hyderabad (SBH). These were merged with SBI effective April 1, 2017.
- Nationalized Banks (others): Banks that were nationalized in 1969 (first batch of 14 banks) and in 1980 (second batch of 6 banks). Several have since been merged. Major nationalized banks include:
- Punjab National Bank (PNB) — now merged with OBC and United India Insurance (effective September 1, 2022) to form Punjab National Bank
- Bank of Baroda (BoB) — merged with Vijaya Bank and Dena Bank in 2019 to form India’s second-largest bank
- Bank of India (BoI)
- Central Bank of India
- Indian Overseas Bank (IOB)
- UCO Bank
- Union Bank of India
- Canara Bank — merged with Syndicate Bank in 2020
- Indian Bank — merged with Allahabad Bank in 2020
- Bank of Maharashtra
As of 2024, there are 12 Public Sector Banks in India (including SBI and its associate):
Private Sector Banks
Private Sector Banks are banks where private entities (individuals, corporate groups, foreign shareholders) hold a majority stake. They operate with greater operational flexibility than PSBs but are equally regulated by the RBI.
Old Private Sector Banks: Established before 1991, these include:
- HDFC Bank (Housing Development Finance Corporation — now the largest private sector bank by market capitalization)
- ICICI Bank (Industrial Credit and Investment Corporation of India)
- Axis Bank (formerly UTI Bank — UTI Group)
- IDBI Bank (Industrial Development Bank of India — originally a development finance institution, converted to bank in 2004)
- Kotak Mahindra Bank
- IndusInd Bank
- Yes Bank (reconstructed in 2020 after RBI initiated reconstruction scheme)
New Private Sector Banks: After the liberalization of 1991, RBI issued guidelines permitting the establishment of new private sector banks. The first set included IDBI Bank (1998), UTI Bank (now Axis Bank, 1994), and ICICI Bank (1994). These new entrants transformed Indian banking through technology adoption, customer service innovation, and product diversification.
Foreign Banks Operating in India
Foreign banks operate in India through branch offices, subsidiaries, or representative offices. Major foreign banks operating in India include Citibank, HSBC, Standard Chartered Bank, Deutsche Bank, Barclays Bank, and DBS Bank. Foreign banks are subject to Indian banking regulations and RBI’s branch authorization policy. They are required to maintain a minimum 30% of their branches in rural and semi-urban areas.
Small Finance Banks (SFBs)
Small Finance Banks were established under RBI guidelines in 2017 to provide financial inclusion to underserved sections — small and marginal farmers, micro and small enterprises, unorganized sector entities, and low-income households. Unlike commercial banks, SFBs cannot lend to large corporations and have a cap on maximum loan size.
Examples: Ujjivan Small Finance Bank, AU Small Finance Bank, Equitas Small Finance Bank, Jana Small Finance Bank, Fincare Small Finance Bank.
Payment Banks
Payment Banks were created to deepen digital financial inclusion by providing small savings accounts, remittance services, and payment solutions to the unbanked and underbanked populations. They cannot lend or issue credit cards. Examples: Paytm Payments Bank, Airtel Payments Bank, India Post Payments Bank, Fino Payments Bank, NSDL Payments Bank.
Reserve Bank of India (RBI): The Apex Bank
The Reserve Bank of India (RBI) was established on April 1, 1935, under the Reserve Bank of India Act, 1934. It is the central bank of India and serves as the regulator and supervisor of the entire banking and financial system.
Functions of RBI
Monetary Policy: The RBI formulates and implements India’s monetary policy with the primary objective of maintaining price stability while supporting economic growth. The RBI’s Monetary Policy Committee (MPC) — established in 2016 — sets the policy repo rate (the rate at which RBI lends to commercial banks). The MPC meets six times a year. The inflation target is set by the Government of India at 4% (±2%).
Currency Issue and Management: The RBI is the sole authority for issuing currency notes in India (one rupee notes are issued by the Finance Ministry). The RBI also manages the distribution and destruction of currency.
Banker to the Government: The RBI acts as the banker, agent, and fiscal agent to the central and state governments. It manages government accounts, handles public debt, and provides temporary advances to the government.
Banker to Banks: The RBI maintains accounts for all commercial banks and acts as the lender of last resort. Banks maintain reserve deposits (CRR — Cash Reserve Ratio) with the RBI.
Regulation and Supervision: The RBI regulates and supervises banks and financial institutions through various mechanisms including on-site inspection, off-site surveillance, prompt corrective action (PCA) framework, and supervisory colleges. The RBI’s Department of Banking Supervision (DBS) oversees commercial banks.
Foreign Exchange Management: The RBI regulates India’s foreign exchange market under the Foreign Exchange Management Act (FEMA), 1999, and manages India’s foreign currency reserves.
Key Policy Rates and Ratios
| Instrument | Description | Current Rate (approx.) |
|---|---|---|
| Repo Rate | Rate at which RBI lends to banks (overnight) | 6.50% |
| Reverse Repo Rate | Rate RBI pays banks for deposits | 3.35% |
| MSF (Marginal Standing Facility) | Emergency borrowing from RBI at repo+0.25% | 6.75% |
| CRR (Cash Reserve Ratio) | % of NDTL banks must maintain with RBI | 4.50% |
| SLR (Statutory Liquidity Ratio) | % of NDTL banks must invest in govt securities | 18.00% |
Banking Structure: Lead Bank Scheme and Financial Inclusion
Lead Bank Scheme (LBS): Under this scheme, one major bank (usually a PSB) is designated as the “Lead Bank” for each district in India. The Lead Bank coordinates the banking services in the district, identifies priority sector lending targets, and ensures financial inclusion.
Priority Sector Lending (PSL): Banks are required to lend a certain percentage of their Net Bank Credit (NBC) to the priority sector — agricultural loans, small and micro enterprises, education loans, housing loans to the poor, and loans to weaker sections. For foreign banks operating in India, the target is 40% of NBC; for domestic banks, it is 40% of ANBC (Adjusted Net Bank Credit).
Key priority sector categories:
- Agriculture (including farm loans, warehousing, fisheries)
- Micro, Small and Medium Enterprises (MSMEs)
- Education loans
- Housing loans (up to ₹35 lakh in non-metropolitan areas)
- Social infrastructure (schools, hospitals, sanitation)
- Renewable energy
- Weaker sections (women, SC/ST, minorities, disabled)
Recent Reforms and Developments
Digital Banking: India has undergone a remarkable digital banking transformation, driven by the Unified Payments Interface (UPI) — a real-time payment system launched in 2016 by the National Payments Corporation of India (NPCI). UPI has become the world’s largest instant payment system, processing billions of transactions monthly. BHIM app, Google Pay, PhonePe, and Paytm are major UPI apps.
Jan Dhan Yojana (2014): Pradhan Mantri Jan Dhan Yojana opened bank accounts for over 500 million unbanked Indians in the world’s largest financial inclusion program. Account holders received a RuPay debit card, ₹2 lakh accident insurance cover, and ₹30,000 life insurance cover.
Demonetization (November 8, 2016): The government invalidated ₹500 and ₹1,000 currency notes (86% of cash in circulation) in a sudden move aimed at curbing black money, corruption, and counterfeit currency. This had a profound short-term impact on the economy and significantly accelerated digital payment adoption.
Bank Mergers: The government has actively pursued bank consolidation to create larger, stronger banks. Major mergers include BoB + Vijaya Bank + Dena Bank (2019), SBI + its associate banks (2017), PNB + OBC + United India Insurance (2022), Canara Bank + Syndicate Bank (2020), Indian Bank + Allahabad Bank (2020).
⚡ Exam tip: The RBI was established in 1935. The Monetary Policy Committee (MPC) was set up in 2016 and meets 6 times a year. The inflation target is 4% ± 2%. Jan Dhan Yojana was launched in 2014. Demonetization occurred on November 8, 2016. SBI was originally the Imperial Bank of India (1870). UPI is India’s real-time payment system operated by NPCI.
