Indian Banking System: Structure, Types, Functions and Evolution

The Indian banking system refers to the network of banks and banking institutions that accept deposits, provide credit, facilitate payments and offer other financial services under the regulatory framework established by the Reserve Bank of India (RBI) and applicable laws.

Banks act as financial intermediaries. They mobilise funds from individuals and organisations with surplus money and channel those funds towards borrowers who need financing.

Some of the key activities of banks include:

• Accepting deposits
• Providing loans and advances
• Facilitating domestic and international payments
• Supporting savings and investment
• Providing remittance services
• Creating and transmitting credit
• Supporting businesses and entrepreneurs
• Promoting financial inclusion

The banking system therefore connects savers, borrowers, businesses and the wider economy.

The history of the Indian banking system can be understood through several stages, from indigenous banking practices and colonial-era institutions to nationalisation, economic reforms and digital banking.

Early Banking in India

Before the development of modern banks, financial activities were carried out by indigenous bankers, moneylenders, merchants and other financial intermediaries. They provided credit to traders, farmers and businesses and played an important role in local commerce.

The development of formal banking institutions gradually changed this landscape.

Presidency Banks and the Imperial Bank of India

During the colonial period, the Bank of Bengal, Bank of Bombay and Bank of Madras were established as Presidency Banks.

These three institutions were later merged in 1921 to form the Imperial Bank of India.

A significant milestone came after independence when the Imperial Bank of India was nationalised and became the State Bank of India (SBI) in 1955. The RBI notes that the establishment of SBI was part of efforts to strengthen institutional banking and expand rural credit.

Establishment of the Reserve Bank of India

The Reserve Bank of India began operations in 1935 under the Reserve Bank of India Act, 1934. It became a central institution in India’s monetary and banking framework.

The RBI’s responsibilities have expanded over time and include monetary policy, regulation and supervision of banks, management of foreign exchange and oversight of payment systems.

Banking Regulation Act, 1949

The Banking Regulation Act, 1949 established an important legal framework for regulating banking companies in India. It strengthened the regulatory role of the RBI and provided a framework for areas such as licensing, banking operations and supervision.

Nationalisation of Banks

Bank nationalisation became a major turning point in the evolution of the Indian banking system.

In 1969, 14 major commercial banks were nationalised. Six more banks were nationalised in 1980. These measures were intended to expand access to institutional credit and increase the flow of finance towards priority sectors and underserved groups.

The period following nationalisation saw significant expansion in India’s banking network. RBI research records that the number of bank branches increased substantially between 1969 and 1990 as banking expanded geographically.

Regional Rural Banks

Regional Rural Banks (RRBs) were introduced in 1975 to improve institutional credit delivery in rural areas.

RRBs were designed to combine the local knowledge and rural focus associated with cooperative institutions with the resources and banking expertise of commercial banks.

Banking Reforms After 1991

The economic reforms of the 1990s brought significant changes to India’s banking sector. The emphasis gradually shifted towards greater competition, financial sector efficiency, market-based interest rates and technological modernisation.

Private sector banks expanded, banking technology improved and the sector became increasingly competitive. RBI research describes the post-1991 period as a shift away from administered rates and towards greater market orientation and financial sector reform.

Digital Transformation

The subsequent decades brought rapid adoption of ATMs, internet banking, mobile banking and electronic payment systems.

Payment infrastructure such as NEFT and RTGS became important components of India’s electronic payments ecosystem, while UPI significantly accelerated the adoption of instant digital payments.

Today, the banking sector combines traditional banking infrastructure with digital channels, fintech partnerships, data analytics and increasingly sophisticated technology.

The structure of the Indian banking system is diverse. It includes the central bank, commercial banks, cooperative banks and specialised banking institutions.

A simplified structure is:

Reserve Bank of India

↓

Commercial Banks

• Public sector banks
• Private sector banks
• Foreign banks
• Regional Rural Banks
• Small Finance Banks

Cooperative Banks

• Urban Cooperative Banks
• Rural Cooperative Banks

Payments Banks

In addition, India has several other financial institutions, including development-oriented financial institutions and NBFCs, which complement the banking sector but are not banks in the legal sense.

The Reserve Bank of India is India’s central bank and plays a central role in maintaining monetary and financial stability.

Its responsibilities include:

• Formulating and implementing monetary policy
• Regulating and supervising banks
• Managing currency issuance
• Managing foreign exchange reserves
• Acting as banker to the government
• Acting as banker to banks
• Overseeing payment and settlement systems
• Supporting financial inclusion

RBI as Monetary Authority

The RBI uses monetary policy tools to influence liquidity, interest rates and overall financial conditions in the economy.

These tools include:

• Repo rate
• Cash Reserve Ratio (CRR)
• Statutory Liquidity Ratio (SLR)
• Open Market Operations

The RBI’s monetary policy framework focuses on maintaining price stability while keeping growth in mind.

RBI as Banker to the Government

The RBI manages banking transactions for the Central Government and certain state governments. It also manages government debt and facilitates government receipts and payments.

RBI as Banker’s Bank

The RBI maintains certain reserves of banks and provides liquidity support to the banking system when required.

This role contributes to the stability and smooth functioning of the financial system.

RBI as Banking Regulator

The RBI regulates and supervises various categories of banks and certain other financial institutions. Its regulatory responsibilities include areas such as licensing, prudential norms, governance, risk management and depositor protection.

Banks in India can be classified in several ways. One important classification is based on whether they are included in the Second Schedule of the RBI Act, 1934.

Scheduled Banks

Scheduled banks are included in the Second Schedule of the RBI Act, 1934 and meet the conditions specified under the Act.

Scheduled banks include categories such as:

• Public sector banks
• Private sector banks
• Foreign banks
• Regional Rural Banks
• Small Finance Banks
• Payments Banks

Non-Scheduled Banks

Non-scheduled banks are banks that are not included in the Second Schedule of the RBI Act, 1934.

This distinction is different from the broader classification of banks by ownership or function.

Commercial banks form a major part of the Indian banking sector. They accept deposits and provide loans and other banking services to individuals, businesses and institutions.

Commercial banks can be broadly grouped into public sector banks, private sector banks, foreign banks and certain specialised categories.

Public Sector Banks

Public sector banks have significant government ownership.

Examples include:

• State Bank of India
• Bank of Baroda
• Punjab National Bank
• Canara Bank
• Union Bank of India
• Bank of India

The public sector banking network has historically played an important role in financial inclusion, priority sector lending and government-backed financial programmes.

Private Sector Banks

Private sector banks are privately owned banking institutions operating under RBI regulation.

Examples include:

• HDFC Bank
• ICICI Bank
• Axis Bank
• Kotak Mahindra Bank
• IndusInd Bank

Private sector banks have played a significant role in technology adoption, digital banking and competition within the sector.

Foreign Banks

Foreign banks are banks headquartered outside India that operate in the country through branches or other permitted structures.

They serve corporate customers, international businesses and other segments depending on their operations and regulatory permissions.

Regional Rural Banks

RRBs primarily focus on the banking and credit requirements of rural areas. They serve groups such as farmers, agricultural workers, small businesses and rural entrepreneurs.

Their role is particularly relevant to rural credit and financial inclusion.

Cooperative banks operate on cooperative principles and are designed to serve their members and local communities.

They are broadly divided into urban and rural cooperative institutions.

Rural Cooperative Banks

The rural cooperative credit structure includes institutions such as:

• State Cooperative Banks
• District Central Cooperative Banks
• Primary Agricultural Credit Societies

These institutions play an important role in providing credit to the agricultural and rural sectors.

Urban Cooperative Banks

Urban Cooperative Banks serve customers primarily in urban and semi-urban areas. They cater to individuals, small businesses and local communities.

Cooperative banking is subject to a regulatory framework involving both the RBI and, depending on the institution and applicable law, cooperative authorities.

Payments Banks were introduced with a focus on deposits, payments, remittances and financial inclusion.

Their business model differs from that of conventional commercial banks, particularly with respect to lending activities.

Examples of payments banks have included India Post Payments Bank, Airtel Payments Bank and FINO Payments Bank. The status of individual institutions can change, so customers should verify the latest RBI information before relying on an institution’s current licence or operating status.

Non-Banking Financial Companies, or NBFCs, provide several financial services that overlap with those offered by banks. However, NBFCs are not banks and operate under a different regulatory framework.

NBFCs complement banks by providing credit and other financial services to consumers, businesses and underserved segments of the economy.

Mobilisation of Savings

Banks encourage individuals and organisations to deposit their surplus funds. These deposits can then be channelled into productive economic activities.

Providing Credit

Banks provide loans to individuals, businesses, farmers and other borrowers. Credit can support consumption, education, housing, business expansion and investment.

Credit Creation

Commercial banking enables the creation and transmission of credit within the financial system, subject to regulatory requirements and monetary conditions.

Facilitating Payments

Banks enable individuals and businesses to make payments through cash, cheques, cards, internet banking and digital payment systems.

India’s electronic payment infrastructure includes systems such as NEFT and RTGS, alongside retail digital payment channels.

Supporting Economic Development

Bank credit supports sectors such as agriculture, manufacturing, infrastructure, services and small businesses.

Promoting Financial Inclusion

Banks help bring individuals and communities into the formal financial system through basic accounts, credit, insurance-linked services, digital payments and other financial products.

The RBI’s financial inclusion strategy has included initiatives such as bank nationalisation, financial access programmes and digital financial services.

Priority Sector Lending (PSL) is an important feature of India’s banking framework.

It is designed to ensure adequate institutional credit reaches sectors whose financing needs are considered important for socio-economic development.

The RBI’s current Priority Sector Lending Directions, effective from April 1, 2025, apply to commercial banks including Regional Rural Banks and Small Finance Banks, as well as certain cooperative banks and Local Area Banks.

Priority sectors include areas such as:

• Agriculture
• Micro, Small and Medium Enterprises
• Export credit
• Education
• Housing
• Renewable energy
• Other specified underserved segments

Financial inclusion aims to make appropriate financial services accessible and affordable to sections of society that may otherwise remain outside the formal financial system.

Important developments include:

• Basic bank accounts
• Rural banking expansion
• Direct Benefit Transfers
• Digital payments
• Microcredit
• Small Finance Banks
• Financial literacy initiatives

Digital infrastructure has also made it easier for customers in different parts of the country to access payments and financial services.

Technology has fundamentally changed how banking services are delivered.

Internet and Mobile Banking

Customers can now perform many routine banking activities without visiting a branch. These include checking balances, transferring funds, paying bills and managing accounts.

UPI and Digital Payments

The Unified Payments Interface has significantly changed retail payments in India by enabling interoperable, real-time account-to-account transactions through participating applications and banks.

Artificial Intelligence

Banks are increasingly exploring AI and machine learning for applications such as:

• Fraud detection
• Customer support
• Risk assessment
• Personalisation
• Process automation
• Data analysis

Cybersecurity

As banking becomes increasingly digital, cybersecurity has become a critical priority. Banks need systems and processes to protect customer information, transactions and digital infrastructure from evolving threats.

Some banks are considered particularly important to India’s financial system because their failure could have a significant impact on the wider economy.

These are classified as Domestic Systemically Important Banks, or D-SIBs, under the RBI framework.

In the RBI’s 2024 list, State Bank of India, HDFC Bank and ICICI Bank continued to be identified as D-SIBs.

Such banks are subject to additional capital requirements based on their systemic importance.

Basel norms are international standards designed to strengthen banks’ capital, liquidity and risk-management frameworks.

Basel I

Basel I primarily focused on credit risk and capital adequacy.

Basel II

Basel II expanded the framework to cover:

1. Capital adequacy
2. Supervisory review
3. Market discipline

It also incorporated credit, market and operational risks.

Basel III

Basel III was developed following the global financial crisis and introduced stronger requirements for capital, liquidity and risk resilience.

These standards are intended to make banks better equipped to withstand financial shocks.

The Capital to Risk-Weighted Assets Ratio, or CRAR, indicates a bank’s capital position relative to the risks associated with its assets.

A simplified representation is:

CRAR = (Eligible Bank Capital / Risk-Weighted Assets) × 100

Regulators use capital adequacy requirements as part of the broader prudential framework for maintaining banking stability.

The evolution of the Indian banking system continues as technology, regulation and customer expectations change.

Some important trends include:

Greater Digital Adoption

Customers increasingly use mobile applications and digital channels for routine banking and payments.

Fintech and Bank Partnerships

Banks and fintech companies increasingly collaborate to improve payments, lending, customer experience and financial technology infrastructure.

AI and Automation

Artificial intelligence and automation are being explored to improve operational efficiency, fraud monitoring, customer service and decision-making.

Greater Focus on Cybersecurity

As digital transactions increase, banks need stronger cybersecurity, fraud prevention and data protection mechanisms.

Financial Inclusion

Expanding access to formal financial services remains an important objective, particularly for rural communities, low-income households and small businesses.

Knowledge of the Indian banking system is useful for students pursuing finance, economics, commerce, management and related disciplines.

It can help learners understand:

• How banks support economic activity
