1. Meaning, scope and economic role of banking
Banking is the regulated business of accepting deposits, facilitating payments and, where permitted under the institution’s licence, extending credit. In India, the Banking Regulation Act, 1949 provides the central legal framework for banking companies, subject to applicable statutory provisions.
The Indian banking system connects savers, borrowers, households, firms, governments and financial markets. It supports economic activity while operating within prudential, customer-protection and payment-system rules.
| Function | How it works | Indian illustration |
|---|---|---|
| Deposit mobilisation | Banks accept permitted deposits and maintain accounts. | Savings and current accounts |
| Credit intermediation | Funds are channelled to eligible borrowers based on credit appraisal. | MSME working-capital loan |
| Payments | Transfer, settlement and transaction services. | NEFT, RTGS, UPI-enabled bank accounts |
| Financial inclusion | Services reach underserved customers and locations. | Business correspondents, basic savings accounts |
| Monetary transmission | Policy rates influence bank funding and lending conditions. | Changes in interest rates over time |
Not every institution called a financial institution is a bank. NBFCs generally cannot accept demand deposits or issue cheques drawn on themselves.
2. Historical evolution: major milestones
Indian banking developed through the presidency-bank era, the rise of Indian joint-stock banks, establishment of the central bank, public ownership of selected banks, post-1991 reforms and the digital-payments era.
| Year / period | Milestone | Importance |
|---|---|---|
| 1806 / 1809 | Bank of Calcutta, later Bank of Bengal | Presidency-bank lineage |
| 1840 | Bank of Bombay | Presidency bank |
| 1843 | Bank of Madras | Presidency bank |
| 1921 | Imperial Bank of India established | Three presidency banks amalgamated |
| 1935 | Reserve Bank of India began operations | Central banking institution |
| 1949 | RBI nationalised; Banking Regulation Act enacted | Public central bank and modern bank regulation |
| 1955 | State Bank of India constituted | Imperial Bank transformed into SBI |
| 1969 | 14 major commercial banks nationalised | Expanded public-sector banking |
| 1975 / 1976 | First RRBs established; RRB Act enacted | Rural institutional credit |
| 1980 | Six additional commercial banks nationalised | Public-sector expansion |
| 1991 onward | Financial-sector reforms and new private banks | Competition and prudential reforms |
| 2016 | UPI launched | Interoperable digital payments |
| 2017–2020 | Major public-sector bank amalgamations | Consolidation |
| 2025 | One State–One RRB amalgamation phase effective | RRB consolidation |
Historical names and institutional transformations differ from current legal bank names. Avoid treating all historical institutions as current banks.
3. Structure and classification of banks in India
Indian banks can be classified using multiple independent dimensions. The most important are ownership, schedule status, licence or permitted activities, and customer/geographic orientation.
| Classification dimension | Examples / forms | What it answers |
|---|---|---|
| Ownership | Public sector, private sector, foreign | Who controls/owns the institution? |
| Statutory schedule | Scheduled or non-scheduled | Is it included in the Second Schedule? |
| Licence and activities | Universal commercial, SFB, payments bank | What activities are permitted? |
| Geographic or clientele focus | RRB, local area, cooperative | Whom or where does it serve? |
A private-sector bank may be a scheduled commercial bank. “Scheduled” does not mean government-owned.
4. Public sector banks: complete 2026 list
The Government of India’s Department of Financial Services lists 12 functioning public sector banks. The list below is a dated official snapshot; check the source when reusing it after mergers or restructuring.
| No. | Public sector bank |
|---|---|
| 01 | State Bank of India |
| 02 | Punjab National Bank |
| 03 | Bank of Baroda |
| 04 | Canara Bank |
| 05 | Union Bank of India |
| 06 | Bank of India |
| 07 | Indian Bank |
| 08 | Central Bank of India |
| 09 | Indian Overseas Bank |
| 10 | UCO Bank |
| 11 | Bank of Maharashtra |
| 12 | Punjab & Sind Bank |
Public-sector banks are not synonymous with all scheduled banks. Regulatory and supervisory requirements apply irrespective of ownership category.
Major consolidation phases: five SBI associates and Bharatiya Mahila Bank joined SBI in 2017; Dena and Vijaya Banks joined Bank of Baroda in 2019; four amalgamation groups took effect in 2020.
5. Private-sector banks, foreign banks and local area banks
Private-sector banks are licensed banking companies with private-sector ownership. Foreign banks have their headquarters outside India and operate in India subject to applicable RBI and domestic rules. Local Area Banks operate under a geographically restricted model.
| Category | Examples / key traits | Exam caution |
|---|---|---|
| Private-sector banks | HDFC Bank, ICICI Bank, Axis Bank | Not all privately owned lenders are banks |
| Foreign banks | HSBC, Standard Chartered | Foreign head office; Indian supervision applies |
| Local Area Banks | Restricted local geographical area | Do not confuse with cooperative or regional rural banks |
Ownership, licensing, shareholding and bank status can change. For dynamic bank rosters, refer to the current official RBI lists.
6. Regional rural banks: 2025–2026 framework
RRBs began in 1975 to increase formal credit access for agriculture, rural enterprises and weaker sections. They operate under the Regional Rural Banks Act, 1976 and have government and sponsor-bank ownership.
| Feature | Official framework |
|---|---|
| First RRBs | Five commenced in 1975 |
| Core law | Regional Rural Banks Act, 1976 |
| Ownership ratio | Central government 50%; sponsor bank 35%; state government 15% |
| Current count | 28 RRBs, according to Department of Financial Services |
| 2025 reform | Amalgamations effective 1 May 2025 under One State–One RRB phase |
| Main beneficiaries | Small and marginal farmers, agricultural labourers, artisans, rural entrepreneurs |
Examples from the official list include Tamil Nadu Grama Bank, Karnataka Grameena Bank, Telangana Grameena Bank and Uttar Pradesh Gramin Bank.
A 2025–26 departmental report and the live DFS overview may give differing branch counts because they use different reference dates. The current RRB count of 28 is separately stated.
7. Small finance banks and payments banks
Differentiated banking licences address specific policy needs. Small Finance Banks are aimed especially at underserved depositors and borrowers, whereas Payments Banks are subject to a restricted business model.
| Feature | Small Finance Bank | Payments Bank |
|---|---|---|
| Main purpose | Financial inclusion through deposits and credit | Payments, remittances and permitted deposits |
| Lending | Permitted, subject to norms | Cannot grant ordinary loans from own balance sheet |
| Deposits | Permitted under licence | Permitted demand deposits subject to current RBI rules |
| Example | AU Small Finance Bank; Ujjivan SFB | India Post Payments Bank; Airtel Payments Bank |
| Exam trap | An SFB is a bank, not an NBFC | Cannot be treated as a conventional lending bank |
Deposit ceilings, SFB lending requirements and licensing conditions can change. Avoid memorising old limits from legacy brochures; verify the applicable RBI notification.
8. Cooperative banks and rural cooperative credit structure
Cooperative banking is member-based and institutionally distinct from commercial banking. It has both urban and rural branches of the cooperative credit system, with regulation and supervision depending on institution type and statutory framework.
| Institution | Role | Important distinction |
|---|---|---|
| Urban Cooperative Banks | Banking services to members and other eligible customers | Banking regulation applies; cooperative governance also relevant |
| State Cooperative Banks | Apex institution in state short-term cooperative credit structure | Not identical to an RRB |
| District Central Cooperative Banks | District-level cooperative banking intermediaries | Part of cooperative credit network |
| Primary Agricultural Credit Societies | Village-level cooperative credit entities | PACS are not automatically licensed banks |
For examinations, distinguish “bank”, “credit society”, and “cooperative institution”; their legal permissions and deposit-insurance treatment are not necessarily the same.
9. RBI, banking regulation and core laws
The RBI is India’s central bank, established under the RBI Act, 1934 and operational from 1 April 1935. Its functions include monetary policy implementation, bank regulation and supervision, currency management, payment-system oversight and financial stability.
| Law / authority | Exam relevance |
|---|---|
| Reserve Bank of India Act, 1934 | Central bank; scheduled bank classification; MPC provisions |
| Banking Regulation Act, 1949 | Banking business and regulation |
| Regional Rural Banks Act, 1976 | RRB establishment and governance |
| Payment and Settlement Systems Act, 2007 | Payment systems oversight |
| DICGC Act, 1961 | Deposit insurance |
| SARFAESI Act, 2002 | Specified secured-creditor enforcement |
| Insolvency and Bankruptcy Code, 2016 | Corporate insolvency and resolution framework |
Regulatory rules include prudential capital and liquidity norms, governance expectations, know-your-customer requirements, fair practices and customer protection.
The RBI has both functions. Not every RBI activity is a monetary policy function.
10. Deposits, lending, bank balance sheets and risk
A simplified commercial bank balance sheet records deposits and other borrowings among liabilities, while loans, investments and cash balances are among assets. Interest margins, fee income, asset quality, operational efficiency and risk management influence bank performance.
| Term | Meaning |
|---|---|
| CASA | Current-account and savings-account deposits |
| NIM | Net interest income relative to average earning assets |
| CRAR / CAR | Regulatory capital relative to risk-weighted assets |
| Gross NPA | Non-performing assets before associated deductions |
| Net NPA | NPAs net of specified provisions/adjustments |
| Provisioning | Recognising expected or incurred credit losses under applicable norms |
| Liquidity risk | Risk of inability to meet obligations as due |
| Credit risk | Risk that a borrower or counterparty fails to meet obligations |
CRAR is a ratio, not the amount of bank capital. A fall in NPA ratio need not imply that every loan is performing.
11. Financial inclusion and customer protection
Financial inclusion seeks affordable, appropriate and effective access to accounts, payments, credit, insurance and other services. Important delivery mechanisms include bank branches, business correspondents, basic savings accounts and digital channels.
| Initiative / mechanism | Purpose |
|---|---|
| PM Jan Dhan Yojana | Basic account access and financial inclusion |
| Business Correspondents | Last-mile delivery of banking services |
| UPI | Interoperable instant payment interface operated by NPCI |
| DICGC deposit insurance | Eligible deposits protected up to ₹5 lakh per depositor per insured bank, in the same capacity and right |
| RBI Integrated Ombudsman Scheme | Grievance-redress mechanism within its defined coverage |
₹5 lakh applies per depositor per insured bank in the same right and capacity, not simply per separate account.
12. Digital banking and payment infrastructure
India’s banking infrastructure combines branches, ATMs, mobile banking, internet banking and regulated payment networks. The National Payments Corporation of India develops and operates important retail payment systems.
| System | Characteristic |
|---|---|
| UPI | Interoperable real-time retail payment mechanism |
| IMPS | Immediate payment service |
| NEFT | Electronic funds transfer system operated by RBI |
| RTGS | Real-time gross settlement for eligible transactions |
| AePS | Aadhaar Enabled Payment System |
| RuPay | Domestic card payment network |
No legitimate exam note should encourage sharing OTPs, PINs or passwords. Authentication, dispute resolution and fraud prevention are part of banking awareness.
13. 2025–2026 banking reforms and dated sector indicators
Recent official material documents structural reform and the evolving size of banking operations. Distinguish announcements, effective changes and end-of-period statistical snapshots.
| Indicator / development | Value / date | Source interpretation |
|---|---|---|
| Public sector banks | 12 (DFS current listing) | Institution count; not branch count |
| Regional rural banks | 28 (DFS current overview) | After 2025 amalgamation |
| Commercial-bank functioning offices | 1,79,097 at 31 March 2026 | DFS banking analytics; includes listed bank groups |
| PSB functioning offices | 95,658 at 31 March 2026 | DFS banking analytics |
| Private bank functioning offices | 50,716 at 31 March 2026 | DFS banking analytics |
