Structure of Indian Banking System — RBI, PSBs, Private & Foreign Banks
Free study material · concepts, shortcuts & solved questions
Ask any coaching-institute faculty which topic quietly decides the fate of the Banking Awareness section, and most will say the same thing: the structure of the Indian banking system. It sounds like dry organisational trivia, but it is actually the skeleton on which almost every other chapter of this book hangs — monetary policy, priority sector lending, financial inclusion schemes, NPA resolution, all of it makes sense only once you know who does what in the system. Examiners love this topic precisely because it is fact-dense and unambiguous: either you know that Bank of Baroda merged with Dena Bank and Vijaya Bank, or you do not. There is no middle ground, which is exactly why 3-5 questions from this single chapter show up in nearly every IBPS, SBI and RRB prelims paper.
The good news is that this structure has a logic to it. Once you understand the pyramid — a central regulator at the top, several categories of banks working under its supervision, and a handful of committees and reforms that reshaped the pyramid over seven decades — the facts stop being random and start being predictable. This chapter builds that pyramid brick by brick.
The Two-Tier Structure: Regulator and Regulated
Indian banking is organised as a two-tier system. At the top sits the Reserve Bank of India (RBI), the central bank and sole regulator of the monetary and banking system. Below it operates the vast universe of commercial banks, cooperative banks, and specialised financial institutions that actually deal with the public. The RBI does not accept deposits from ordinary citizens or give out personal loans — its "customers" are banks, the government, and the financial system as a whole. Every other bank you have ever dealt with, whether SBI, HDFC Bank or your local Regional Rural Bank, sits in the second tier and answers to the RBI.
[Memory Hook] Think of RBI as the "bankers' bank" — just as you keep your money in a bank, banks keep their reserves and accounts with the RBI. This single idea explains why RBI can control money supply, fix interest rates, and act as lender of last resort during a crisis.
Reserve Bank of India — Origin and Core Functions
The RBI was established on April 1, 1935 under the Reserve Bank of India Act, 1934, following the recommendations of the Hilton Young Commission. It was originally a privately owned institution and was nationalized on January 1, 1949, making it fully government-owned ever since. Its headquarters is in Mumbai, and it currently has four regional offices in Delhi, Chennai, Kolkata and Mumbai, along with numerous regional and sub-offices across the country.
RBI performs multiple roles simultaneously:
- Note-issuing authority: RBI has the sole right to issue currency notes in India (except the one-rupee note and coins, which are issued by the Ministry of Finance, Government of India, though circulated by RBI).
- Banker to the Government: manages the government's banking transactions, public debt, and ways and means advances.
- Banker's bank: holds the cash reserves of commercial banks and acts as lender of last resort.
- Regulator and supervisor: licenses banks, sets prudential norms, conducts inspections, and can even cancel a bank's licence.
- Monetary authority: formulates and implements monetary policy through the Monetary Policy Committee (MPC), controlling inflation and ensuring adequate credit flow.
- Manager of foreign exchange: administers the Foreign Exchange Management Act (FEMA) and manages the country's forex reserves.
- Developmental role: promotes financial inclusion, priority sector lending, and rural credit.
[Exam Trap] Many candidates confuse the issuer of the one-rupee note. Remember: all currency notes (₹2 and above, historically, now ₹5 to ₹2000) are issued by RBI and bear the RBI Governor's signature, but the one-rupee note and all coins are issued by the Government of India and bear the signature of the Finance Secretary — the one-rupee note carries no RBI Governor signature at all.
Governance of RBI
RBI is governed by a Central Board of Directors, headed by the Governor, who is appointed by the Government of India, typically for a term of three years (extendable). The Governor is assisted by a maximum of four Deputy Governors. As of the current cycle, Sanjay Malhotra serves as the Governor of RBI, having taken charge in December 2024. Monetary policy decisions are taken by the six-member Monetary Policy Committee (MPC), constituted under the RBI Act (amended in 2016), consisting of three RBI members (including the Governor as Chairperson) and three external members appointed by the Government.
Evolution of Commercial Banking: The Nationalization Story
No topic in this chapter is asked about more consistently than bank nationalization, so let's get the timeline absolutely straight.
Pre-Independence and Early Years
The oldest bank in India still functioning is the State Bank of India, whose earliest predecessor, the Bank of Calcutta, was established in 1806 (later renamed Bank of Bengal). Along with the Bank of Bombay and Bank of Madras, these three "Presidency Banks" were merged in 1921 to form the Imperial Bank of India, which was itself transformed into the State Bank of India in 1955 after the Government of India acquired a majority stake, acting on the recommendation of the All India Rural Credit Survey Committee.
The 1969 Nationalization
On July 19, 1969, the Government of India, under Prime Minister Indira Gandhi, nationalized 14 major commercial banks, each having deposits of over ₹50 crore. The stated objectives were to break the concentration of economic power in a few private hands, extend banking to rural and unbanked areas, and channel credit toward priority sectors like agriculture and small industry.
The 1980 Nationalization
A second round followed on April 15, 1980, when 6 more banks were nationalized, each with deposits exceeding ₹200 crore. This brought the total number of nationalized banks to 20 (plus SBI and its associates, giving public sector banking near-total dominance by the early 1980s).
[Memory Hook] Remember it as "69 for 14, 80 for 6" — 1969 nationalized 14 banks, 1980 nationalized 6 banks. Total: 20 nationalized banks, a figure frequently tested directly.
[Real-World Example] New Bank of India, one of the 6 banks nationalized in 1980, was later merged into Punjab National Bank in 1993 — this was actually the first-ever merger of a public sector bank in independent India, well before the big consolidation wave of 2017-2020.
Public Sector Banks (PSBs) Today: The Mega-Merger Era
Between 2017 and 2020, the Government of India carried out a sweeping consolidation of public sector banks to create fewer, stronger, globally competitive banks. This process reduced the number of PSBs from 27 (in 2017) to just 12 today. This is arguably the single most tested fact in this chapter, so know all 12 by name.
Timeline of Mergers
- 2017: State Bank of India merged with its five associate banks (State Bank of Bikaner & Jaipur, State Bank of Mysore, State Bank of Travancore, State Bank of Patiala, State Bank of Hyderabad) and the Bharatiya Mahila Bank.
- April 1, 2019: Bank of Baroda merged with Dena Bank and Vijaya Bank.
- April 1, 2020: The largest consolidation round — Punjab National Bank merged with Oriental Bank of Commerce and United Bank of India; Canara Bank merged with Syndicate Bank; Union Bank of India merged with Andhra Bank and Corporation Bank; Indian Bank merged with Allahabad Bank.
[Exam Trap] A very common trick question asks which bank "absorbed" which — for instance, examiners test that Allahabad Bank merged INTO Indian Bank (Indian Bank is the surviving, anchor bank), not the other way around. Always memorize the anchor bank name, since that is the surviving legal entity.
| # | Public Sector Bank (Current) | Headquarters | Merged/Absorbed Banks |
|---|---|---|---|
| 1 | State Bank of India | Mumbai | 5 associate banks, Bharatiya Mahila Bank |
| 2 | Punjab National Bank | New Delhi | Oriental Bank of Commerce, United Bank of India (also New Bank of India, 1993) |
| 3 | Bank of Baroda | Vadodara | Dena Bank, Vijaya Bank |
| 4 | Canara Bank | Bengaluru | Syndicate Bank |
| 5 | Union Bank of India | Mumbai | Andhra Bank, Corporation Bank |
| 6 | Indian Bank | Chennai | Allahabad Bank |
| 7 | Bank of India | Mumbai | No merger (standalone) |
| 8 | Central Bank of India | Mumbai | No merger (standalone) |
| 9 | Indian Overseas Bank | Chennai | No merger (standalone) |
| 10 | UCO Bank | Kolkata | No merger (standalone) |
| 11 | Bank of Maharashtra | Pune | No merger (standalone) |
| 12 | Punjab & Sind Bank | New Delhi | No merger (standalone) |
[Memory Hook] The six "standalone" PSBs that were never merged can be remembered with the phrase "BUCK-MP" — Bank of India, UCO Bank, Central Bank of India, Punjab & Sind Bank, Bank of Maharashtra, and Indian Overseas Bank (rearranged, but the acronym letters BUCK-MP help you list all six without missing one).
Private Sector Banks
Private sector banks are owned predominantly by private shareholders rather than the government, though they remain fully regulated and licensed by RBI like any other commercial bank. India's private banking sector is generally divided into "old" private banks (that survived the nationalization era without being taken over) and "new generation" private banks (licensed after the 1991 liberalization reforms).
New Generation Private Banks
Following the recommendations of the Narasimham Committee on financial sector reforms, RBI issued fresh private bank licences from 1993 onward. This gave birth to banks such as HDFC Bank, ICICI Bank, Axis Bank (originally UTI Bank) and IndusInd Bank. A second wave of "new generation" licences was issued in 2013-14, resulting in Bandhan Bank and IDFC First Bank receiving universal banking licences.
| Bank | Headquarters | Founded | Category |
|---|---|---|---|
| HDFC Bank | Mumbai | 1994 | New generation private (merged with parent HDFC Ltd. in 2023) |
| ICICI Bank | Mumbai | 1994 | New generation private |
| Axis Bank | Mumbai | 1994 | New generation private |
| Kotak Mahindra Bank | Mumbai | 2003 (as bank) | New generation private |
| IndusInd Bank | Mumbai | 1994 | New generation private |
| Yes Bank | Mumbai | 2004 | New generation private |
| IDFC First Bank | Mumbai | 2015 | New generation private |
| Bandhan Bank | Kolkata | 2015 | New generation private |
| Federal Bank | Kochi | 1931 | Old private bank |
| South Indian Bank | Thrissur | 1929 | Old private bank |
| Karur Vysya Bank | Karur | 1916 | Old private bank |
| Jammu & Kashmir Bank | Srinagar | 1938 | Old private bank (state government holds majority stake) |
| Karnataka Bank | Mangaluru | 1924 | Old private bank |
| City Union Bank | Kumbakonam | 1904 | Old private bank |
| DCB Bank | Mumbai | 1930 | Old private bank |
| Tamilnad Mercantile Bank | Thoothukudi | 1921 | Old private bank |
[Exam Trap] A frequently misremembered fact: Jammu & Kashmir Bank is a private sector bank (majority-owned by the Government of Jammu & Kashmir, not the Union Government), NOT a public sector bank — students often wrongly classify it as a PSB simply because "government" appears in its ownership structure. It has never been on the nationalized-bank list.
[Real-World Example] In July 2023, HDFC Bank completed its merger with its parent housing finance company HDFC Ltd., creating one of the largest banks in the world by market capitalisation — a landmark case of a non-banking financial company merging into its own banking subsidiary, reversing the usual direction of such deals.
Foreign Banks Operating in India
Foreign banks operate in India either as branches of the foreign parent (the dominant model) or, since 2013, as Wholly Owned Subsidiaries (WOS) incorporated in India under RBI's 2013 scheme for encouraging foreign banks to locally incorporate. Around 45+ foreign banks currently operate branches in India, though the number fluctuates. Prominent names include Citibank, HSBC, Standard Chartered Bank, Deutsche Bank, DBS Bank India (which converted to a WOS in 2019), Bank of America, and JPMorgan Chase Bank.
[Memory Hook] Foreign banks are licensed under Section 22 of the Banking Regulation Act, 1949, exactly like domestic banks — the "foreign" tag affects ownership and capital rules, but the licensing law is the same statute that governs every commercial bank in India.
Regional Rural Banks (RRBs)
RRBs were established under the Regional Rural Banks Act, 1976, following the recommendations of the Narasimham Committee (1975), with the first RRB — Prathama Bank — set up on October 2, 1975 at Moradabad, Uttar Pradesh, sponsored by Syndicate Bank. RRBs are unique because their ownership is shared in a fixed ratio between the Central Government (50%), the sponsor bank (35%), and the concerned State Government (15%). Their mandate is to provide credit and banking facilities specifically to farmers, agricultural labourers, artisans and small entrepreneurs in rural areas. Under the ongoing "One State, One RRB" consolidation policy, the number of RRBs has been steadily reduced from 196 originally to around 43 as of recent rounds, and further amalgamation is planned to bring most states down to a single RRB each.
[Exam Trap] Do not confuse the RRB ownership ratio (50:35:15 for Centre:Sponsor Bank:State) with the Cooperative Bank structure, which has no such fixed central-sponsor-state formula and is instead organised in a three-tier system (State Cooperative Bank – District Central Cooperative Bank – Primary Agricultural Credit Society).
Comparing the Four Pillars of Commercial Banking
| Feature | Public Sector Banks | Private Sector Banks | Foreign Banks | Regional Rural Banks |
|---|---|---|---|---|
| Majority ownership | Government of India (>50%) | Private shareholders/promoters | Foreign parent entity | Centre (50%), Sponsor bank (35%), State (15%) |
| Regulator | RBI (also under Banking Companies (Acquisition) Acts, 1970/1980) | RBI (Banking Regulation Act, 1949) | RBI (Banking Regulation Act, 1949) | RBI & NABARD (RRB Act, 1976) |
| Primary mandate | Broad-based, social/priority-sector focus | Profit-driven, urban/retail/corporate focus | Corporate, trade finance, wholesale banking | Rural credit, agriculture, financial inclusion |
| Market share (deposits, approx.) | ~58-60% | ~30-32% | ~4-5% | ~2-3% |
| Example | SBI, PNB, Bank of Baroda | HDFC Bank, ICICI Bank, Axis Bank | Citibank, HSBC, Standard Chartered | Prathama UP Gramin Bank, Baroda Rajasthan Kshetriya Gramin Bank |
Key Committees That Shaped the Banking Structure
Examiners love pairing committee names with their core recommendation. This table is worth memorizing cold.
| Committee | Year | Key Recommendation |
|---|---|---|
| Hilton Young Commission | 1926 | Recommended setting up of RBI as India's central bank |
| All India Rural Credit Survey Committee | 1954 | Recommended transformation of Imperial Bank into State Bank of India |
| Narasimham Committee I | 1991 | Financial sector reforms; recommended entry of new private banks, reduction of SLR/CRR |
| Narasimham Committee II | 1998 | Banking sector reforms; capital adequacy, NPA management, universal banking |
| Narasimham Committee (RRBs) | 1975 | Recommended creation of Regional Rural Banks |
| Nachiket Mor Committee | 2013 | Comprehensive financial services for small business and low-income households; led to Payments Banks & Small Finance Banks |
| Raghuram Rajan Committee | 2009 | Financial sector reforms; recommended more competition and financial inclusion |
[Memory Hook] There are two Narasimham Committees — remember "1991 = New banks born" and "1998 = Bank health checked" (capital adequacy and NPA norms). If a question mentions "entry of private banks," it's the 1991 committee; if it mentions "capital adequacy" or "asset quality," it's the 1998 committee.
Newer Categories: Small Finance Banks and Payments Banks
Based on the Nachiket Mor Committee's recommendations, RBI created two new differentiated banking categories in 2015. Small Finance Banks (SFBs) can accept deposits and lend, targeting small businesses, marginal farmers and unorganised sector entities — examples include AU Small Finance Bank, Equitas Small Finance Bank, Ujjivan Small Finance Bank and ESAF Small Finance Bank. Payments Banks can accept deposits (capped at ₹2 lakh per customer) and issue debit cards, but cannot extend loans or issue credit cards — examples include Airtel Payments Bank, India Post Payments Bank, and Fino Payments Bank.
[Exam Trap] A classic trap: Payments Banks cannot lend money at all — this is the single biggest distinguishing feature from Small Finance Banks, which can lend. If a question describes a bank that "cannot issue loans or credit cards," the answer is always a Payments Bank, never an SFB.
Apex and Development Financial Institutions
Beyond commercial banks, several apex institutions support specific sectors, all functioning under RBI's overall regulatory umbrella:
- NABARD (National Bank for Agriculture and Rural Development) — apex body for agricultural and rural credit, established 1982.
- SIDBI (Small Industries Development Bank of India) — apex institution for MSME financing, established 1990.
- EXIM Bank (Export-Import Bank of India) — established 1982, finances and promotes foreign trade.
- NHB (National Housing Bank) — apex institution for housing finance, established 1988.
- NaBFID (National Bank for Financing Infrastructure and Development) — a newer development financial institution set up in 2021 to fund long-term infrastructure projects.
[Real-World Example] When RBI cancelled the licence of the New India Cooperative Bank in 2025 and PMC Bank's assets were transferred to Unity Small Finance Bank in an earlier resolution, it illustrated RBI's supervisory teeth in action — it can and does shut down or force the merger of banks that fail to meet prudential norms, protecting depositors through the Deposit Insurance and Credit Guarantee Corporation (DICGC), which insures deposits up to ₹5 lakh per depositor per bank.
