Monetary Policy & Inflation Control — RBI's Role

Why This Chapter Matters

Every IBPS Clerk, IBPS PO, and SBI Clerk General Awareness paper carries at least two or three questions asking you to sort banks into buckets: which bank is a Public Sector Bank, which is a Small Finance Bank, which is a Payment Bank, and what exactly separates an NBFC from a bank in the eyes of the law. These questions look simple on the surface, but examiners love them precisely because most aspirants blur the categories together after months of mixing static GK with current affairs. A well-prepared candidate answers these in five seconds flat and banks (pun intended) the marks that a rushed candidate loses.

This chapter builds a clean map of India's banking universe: Public Sector Banks and their merger history, Private Sector Banks, Foreign Banks operating in India, Regional Rural Banks, the Cooperative Banking structure, and the newer categories, Payment Banks and Small Finance Banks, created to deepen financial inclusion. It closes with the NBFC-versus-bank distinction, a favourite trap question. The single biggest mistake aspirants make here is memorizing bank names as a flat list without understanding why each category exists. Once you understand the purpose behind each type, the names stop being arbitrary trivia and start sorting themselves.

Public Sector Banks (PSBs)

A Public Sector Bank is a bank in which the Government of India holds a majority stake, generally 50% or more of the paid-up equity capital. These banks trace their public ownership back to the nationalization waves of 1969 and 1980, covered in the previous chapter, and today they form the backbone of India's banking system in terms of branch reach, especially in rural and semi-urban India.

As of 2026, India has 12 Public Sector Banks, down from 27 at the time of the 1969-1980 nationalization era, because of a sweeping consolidation exercise the government carried out between 2017 and 2020. The 12 PSBs today are: State Bank of India (SBI), Punjab National Bank (PNB), Bank of Baroda (BoB), Canara Bank, Union Bank of India, Bank of India, Indian Bank, Central Bank of India, Indian Overseas Bank, UCO Bank, Bank of Maharashtra, and Punjab and Sind Bank.

Exam trap: Aspirants often forget that Punjab and Sind Bank, Bank of Maharashtra, UCO Bank, Central Bank of India, and Indian Overseas Bank remained standalone and were NOT merged into a bigger bank. The mega-mergers absorbed specific banks into specific anchor banks; they did not sweep up every PSB. Learn the mergers as fixed pairs, not a general trend.

The Merger Story, Step by Step

Bank mergers in India did not happen in one single event. They rolled out in phases, each with a clear anchor bank absorbing weaker or smaller associates.

The first major post-2000 consolidation happened inside the State Bank Group. SBI originally had associate banks: State Bank of Bikaner and Jaipur, State Bank of Hyderabad, State Bank of Mysore, State Bank of Patiala, State Bank of Travancore, and State Bank of Indore (merged earlier, in 2010). In April 2017, the remaining five associate banks and Bharatiya Mahila Bank merged into SBI, creating a single institution that instantly became one of the largest banks in the world by branch count and among the top 50 globally by assets.

The second and larger wave came in April 2019, when three separate merger deals were executed together. Bank of Baroda absorbed Vijaya Bank and Dena Bank, forming a combined entity that became India's second-largest PSB by branch network at the time.

The third and biggest wave landed on April 1, 2020, restructuring the remaining mid-sized PSBs into four large anchor banks:

• Punjab National Bank absorbed Oriental Bank of Commerce and United Bank of India.
• Canara Bank absorbed Syndicate Bank.
• Union Bank of India absorbed Andhra Bank and Corporation Bank.
• Indian Bank absorbed Allahabad Bank.

Memory hook: "PUC absorbs, Canara takes one, Union takes two, Indian takes one." Think of it as a seating rearrangement in a classroom on one single date, April 1, 2020: PNB pulls two students (OBC, United Bank) to its bench, Canara pulls one (Syndicate), Union pulls two (Andhra, Corporation), and Indian Bank pulls one (Allahabad). Four benches, six students absorbed, in one reshuffle.

The government's stated rationale for these mergers, a common exam theme, was creating banks with stronger balance sheets, wider technology and risk-management capacity, and better global competitiveness, since fragmented small PSBs struggled to raise capital and absorb bad-loan shocks independently.

Private Sector Banks

Private Sector Banks are banks where private shareholders, not the government, hold the majority stake. India's private banking sector is commonly split into two generations by examiners: old private sector banks, which existed before India's 1991 economic liberalization and survived nationalization because they were too small to fall under the nationalization threshold, and new private sector banks, licensed after RBI opened the sector to private players following the 1991 reforms.

Old private sector banks include names like Federal Bank, South Indian Bank, Karur Vysya Bank, Karnataka Bank, City Union Bank, Jammu & Kashmir Bank, Tamilnad Mercantile Bank, DCB Bank, Dhanlaxmi Bank, and Nainital Bank. Most of these carry a strong regional identity tied to the state or community where they were founded.

New private sector banks emerged after RBI issued fresh licences starting 1993-94, following the recommendations of the Narasimham Committee on financial sector reforms. This generation includes ICICI Bank, HDFC Bank, Axis Bank (originally UTI Bank), IndusInd Bank, Kotak Mahindra Bank, and Yes Bank. A second, smaller licensing round in 2013-14 produced IDFC First Bank and Bandhan Bank, the latter notable as the first bank licence granted primarily on the strength of a microfinance track record.

Exam trap: ICICI Bank and IDBI Bank are frequently mixed up. ICICI Bank is a private sector bank, converted from a development finance institution into a bank in the mid-1990s. IDBI Bank is technically classified differently, having a majority stake held by Life Insurance Corporation of India (LIC) since 2019, making it neither a traditional PSB nor a purely private bank in the classic sense; RBI classifies it as a private sector bank for regulatory purposes, but its LIC-majority ownership makes it a frequently tested oddity.

Memory hook: Picture private banks as two waves of settlers arriving on the same coastline. The "old settlers" (Federal, South Indian, Karur Vysya, Karnataka Bank) arrived before independence-era nationalization and simply stayed small enough to avoid being absorbed by the government. The "new settlers" (ICICI, HDFC, Axis, IndusInd, Kotak) arrived only after the country reopened its shores to private banking in the 1990s liberalization wave.

Foreign Banks

Foreign Banks are banks incorporated outside India that operate within the country, either through branches or, since 2013, through Wholly Owned Subsidiaries (WOS) incorporated in India under Indian company law. RBI's framework encourages large foreign banks to convert into WOS structure because a locally incorporated subsidiary is easier for RBI to regulate and gives depositors more protection under Indian law than a branch of a foreign parent would.

Prominent foreign banks with a significant Indian presence include Standard Chartered Bank, HSBC, Citibank (whose India retail business was sold to Axis Bank in 2023, though its corporate banking arm continues), Deutsche Bank, and DBS Bank India, which converted into India's first large foreign bank WOS in 2019 after absorbing the struggling Lakshmi Vilas Bank in a rescue merger in 2020.

Foreign banks typically concentrate on corporate banking, trade finance, and wealth management in metro cities rather than building the dense rural branch networks that PSBs maintain, since their mandate and comparative advantage lie in cross-border transactions and serving multinational clients.

Regional Rural Banks (RRBs)

Regional Rural Banks (RRBs) were created under the Regional Rural Banks Act, 1976, following the recommendations of the Narasimham Working Group (1975), with the specific goal of extending banking services to rural areas that both commercial banks and cooperative banks were failing to reach adequately. The first RRB, Prathama Bank, was set up in Moradabad, Uttar Pradesh, in 1975, even before the Act formally passed, as a pilot.

An RRB's capital structure is unique and frequently tested: ownership is shared between the Government of India (50%), the concerned State Government (15%), and a sponsor bank, usually a PSB, (35%). Each RRB is sponsored by one specific commercial bank, which provides management support, and operates within a specified area, usually one or a few districts of a state.

RRBs have gone through their own consolidation journey, mirroring the PSB mergers, shrinking from over 196 RRBs at their peak in the 1980s to a much smaller number today through repeated state-wise amalgamation exercises, most recently the "One State, One RRB" push that reduced the count sharply by merging multiple RRBs within a state into a single entity.

Exam trap: Do not confuse RRBs with cooperative banks. RRBs are commercial banks in legal structure, regulated jointly by RBI and NABARD, with government and sponsor-bank ownership. Cooperative banks are member-owned institutions with a completely different legal and regulatory framework, explained next.

Cooperative Banks

Cooperative banks are financial institutions organized on the cooperative principle: members pool resources and the institution exists to serve its member-depositors and member-borrowers rather than external shareholders chasing profit. India's cooperative banking structure splits into two broad arms.

Urban Cooperative Banks (UCBs)

Urban Cooperative Banks operate in cities and towns, serving small traders, self-employed professionals, and urban households. They are registered under state Cooperative Societies Acts (or the Multi-State Cooperative Societies Act for banks operating across states) but are also regulated by RBI for banking functions, a dual-regulation structure, "registrar for cooperative matters, RBI for banking matters," that has historically caused governance gaps and periodic bank failures, the PMC Bank crisis of 2019 being the most cited exam example.

Exam trap: Following governance failures at UCBs, the Banking Regulation (Amendment) Act, 2020, brought UCBs more firmly under RBI's direct banking supervision, closing much of this regulatory gap. This is a commonly tested current-affairs-meets-static fact.

Rural Cooperative Credit Structure

Rural cooperative banking runs on a three-tier structure, cleanly testable as a pyramid:

1. State Cooperative Banks (StCBs) at the state level, the apex tier.
2. District Central Cooperative Banks (DCCBs) at the district level, the middle tier.
3. Primary Agricultural Credit Societies (PACS) at the village level, the base tier, closest to the actual farmer-borrower.

Memory hook: Picture this structure as a village well-water supply chain. PACS is the well itself, right at the farmer's doorstep, where the actual borrowing happens. The DCCB is the pump station at the district level that moves water (funds) between wells. The StCB is the state reservoir at the top, refilling the whole system and connecting it to NABARD, the ultimate source, for refinance.

NABARD (National Bank for Agriculture and Rural Development), established in 1982, sits above this entire rural cooperative and RRB structure, providing refinance and regulatory oversight for agricultural and rural credit, a fact tied closely to this chapter and worth remembering as the thread connecting RRBs and rural cooperative banks together.

Payment Banks

Payment Banks are a differentiated banking licence category introduced by RBI in 2014, on the recommendation of the Nachiket Mor Committee, specifically to extend basic banking and payment services to migrant labourers, low-income households, and small businesses without requiring the full infrastructure of a universal bank.

The defining restriction, a guaranteed exam question, is that Payment Banks cannot lend. They cannot issue loans or credit cards, and each customer account is capped at a maximum deposit balance, historically ₹1 lakh, though RBI raised this ceiling to ₹2 lakh in 2021. Payment Banks can accept deposits, offer a savings and current account, issue debit cards, and provide payment and remittance services, including mobile banking and UPI access, but their core business model runs on transaction fees and interest earned by investing customer deposits into government securities, not on lending margins.

RBI issued Payment Bank licences to 11 applicants in 2015, though several surrendered their licences before launch. Operating Payment Banks today include Airtel Payments Bank, India Post Payments Bank (IPPB), Fino Payments Bank, Paytm Payments Bank (which faced significant RBI restrictions from 2024 onward over compliance lapses), NSDL Payments Bank, and Jio Payments Bank.

Exam trap: Students often assume Payment Banks issue credit cards since they issue debit cards. They do not; the no-lending restriction rules out credit cards entirely, since a credit card is fundamentally a lending product.

Small Finance Banks (SFBs)

Small Finance Banks are the other differentiated licence category RBI introduced in 2014, but with an opposite mandate to Payment Banks: SFBs exist specifically to lend to underserved segments, small business units, micro and small industries, marginal farmers, and unorganized sector entities that struggle to access credit from mainstream banks.

Unlike Payment Banks, SFBs can accept deposits without a balance cap and can lend, essentially functioning as a scaled-down universal bank focused on financial inclusion. RBI's licensing norms required at least 75% of an SFB's Adjusted Net Bank Credit to go toward priority sector lending, and at least 50% of loans to be in ticket sizes of ₹25 lakh or below, ensuring the model stays anchored to small borrowers rather than drifting toward large corporate lending.

RBI issued the first batch of SFB licences in 2015, largely to established microfinance institutions converting into banks. Prominent SFBs operating today include AU Small Finance Bank, Equitas Small Finance Bank, Ujjivan Small Finance Bank, ESAF Small Finance Bank, Suryoday Small Finance Bank, Jana Small Finance Bank, Utkarsh Small Finance Bank, and Capital Small Finance Bank, India's first SFB to begin operations, in 2016.

Memory hook: "Payment banks pay in, Small Finance banks pay out too." Payment Banks only take deposits in and move payments; they never send credit out as loans. Small Finance Banks take deposits in AND send credit out to small borrowers, the "too" marking the extra lending function that Payment Banks lack.

NBFCs vs Banks: The Core Difference

A Non-Banking Financial Company (NBFC) is a company registered under the Companies Act that carries out financial activities like lending, investment, leasing, and hire-purchase, but it is not a bank, even though it can feel like one from a customer's chair. RBI regulates NBFCs under a separate framework from banks, and the differences form one of the most reliably asked comparison questions in banking GA papers.

Feature	Banks	NBFCs
Demand deposits	Can accept (savings/current accounts)	Cannot accept demand deposits
Cheque facility	Can issue chequebooks	Cannot issue cheques drawn on itself
Payment and settlement system	Part of the system (RTGS/NEFT/IMPS)	Not part of the core payment system
Reserve requirements	Must maintain CRR and SLR	Not required to maintain CRR/SLR
Deposit insurance	Deposits insured by DICGC (up to ₹5 lakh)	Deposits (where accepted) not insured by DICGC
Governing law	Banking Regulation Act, 1949	Companies Act, regulated by RBI under RBI Act, 1934 Chapter III-B
Foreign investment	Governed by specific banking FDI norms	Generally under standard FDI rules for the sector

Exam trap: The single most tested line in this comparison is that NBFCs cannot accept demand deposits, meaning no savings or current accounts repayable on demand. Some NBFCs accept fixed deposits or recurring deposit-type instruments, but not demand deposits, and unlike bank deposits, these are not covered by DICGC insurance. If an option in an exam question claims an NBFC offers a "savings account," treat it as false regardless of how the question is otherwise worded.

Well-known NBFCs in India include Bajaj Finance, Muthoot Finance, Shriram Finance, Mahindra & Mahindra Financial Services, Cholamandalam Investment and Finance, LIC Housing Finance, and Tata Capital. NBFCs fill a real economic gap: they often reach borrower segments, gold-loan customers, vehicle-loan buyers, small enterprise borrowers, that traditional banks find costlier to serve through their branch-heavy model, and their lighter regulatory load lets them move faster on loan approvals, though at generally higher interest rates than banks.
