Bank – Meaning, Types & How Banking Works in India
A bank is a financial intermediary, it sits between people who have surplus money and those who need it.
When you deposit money, the bank doesn’t store it in a vault waiting for you; it lends most of it out to home-loan borrowers, businesses, and the government, keeping only a fraction as reserve.
In India, commercial banks are licensed by the RBI and must comply with strict capital adequacy norms set under the Basel III framework.
The RBI also sets the repo rate, which directly influences the interest rates banks charge on loans and offer on deposits.
The Indian banking system includes public sector banks (like State Bank of India and Bank of Baroda), private sector banks (like HDFC Bank and ICICI Bank), small finance banks, payments banks, and cooperative banks — each serving a different segment of the population.
Did You Know? India had 12 public sector banks and over 21 private sector banks as of 2025, serving more than 1.5 billion people — one of the largest banking networks in the world.
How Does a Bank Work?
A bank operates on a simple but carefully managed cycle:
- Accepting deposits — You open a savings account, current account, or fixed deposit. The bank pays you interest for keeping your money with it.
- Maintaining reserves — The RBI requires banks to keep a portion of deposits as the Cash Reserve Ratio (CRR) and invest a portion in government securities as the Statutory Liquidity Ratio (SLR).
- Lending — The remaining money is lent out as home loans, personal loans, business loans, and credit cards, at a higher interest rate.
- Earning the spread — The difference between what a bank earns on loans (say 9%) and what it pays depositors (say 6–7%) is its Net Interest Margin (NIM), the primary source of profit.
- Risk management — Banks assess borrowers’ creditworthiness using CIBIL scores, income proofs, and collateral before sanctioning loans.

Pro Tip: Before opening an FD, compare the interest rates across banks on the RBI’s or aggregator websites. Even a 0.25% difference on a ₹10 lakh FD over 3 years can mean ₹7,500–₹8,000 more in your pocket.
Types of Banks in India
Scheduled Commercial Banks (SCBs)
These are the banks most Indians interact with daily — SBI, HDFC Bank, ICICI Bank, Bank of Baroda, and Yes Bank, among others.
They are listed in the Second Schedule of the RBI Act and are eligible for low-interest borrowing from the RBI.
They offer the full range of services: savings accounts, current accounts, loans, FDs, lockers, and now digital banking.
Public Sector Banks (PSBs)
The government holds a majority stake (over 51%) in these banks. SBI, Bank of Baroda, Punjab National Bank, and Bank of Maharashtra are examples.
PSBs tend to have wider rural branch networks and are often the first choice for government scheme disbursements such as PM Jan Dhan Yojana accounts.
Private Sector Banks
Privately owned and often more aggressive on technology and interest rates. HDFC Bank, ICICI Bank, Axis Bank, and Kotak Mahindra Bank fall here.
Private banks typically offer better digital interfaces and faster loan approvals, but branch coverage in smaller towns can be limited.
Small Finance Banks
Licensed by the RBI to serve underbanked segments — small businesses, marginal farmers, and migrant workers.
They offer higher FD interest rates than most large banks (often 8–9% per annum) in exchange for operating on narrower margins.
Examples: AU Small Finance Bank, Suryoday Small Finance Bank.
Payments Banks
Can accept deposits up to ₹2 lakh but cannot lend. They focus on payments and remittances.
Airtel Payments Bank and India Post Payments Bank are the prominent ones. Useful for people who want a basic digital wallet with some interest on deposits.
Cooperative Banks
Run by cooperative societies at the urban or rural level. Urban Cooperative Banks (UCBs) serve cities, while rural cooperative banks support agriculture.
They are regulated jointly by the RBI and state governments.

Payments Bank | No | Low–Moderate | Digital payments, basic savings |
Cooperative | Yes | Varies | Local/community banking |
Key Components of a Bank Account
- Account Number — A unique identifier for your account. Required for all transfers, whether NEFT, RTGS, or IMPS. Never share this along with your OTP.
- IFSC Code — Indian Financial System Code, an 11-character alphanumeric code identifying the specific branch. Needed for any digital fund transfer.
- MICR Code — Magnetic Ink Character Recognition code printed on cheques. It helps banks process cheque payments quickly.
- CIF Number — Customer Information File number links all your accounts within the same bank to a single customer profile.
- Nomination — You can register one or more nominees on your account. In the event of the account holder’s death, the nominee can claim the funds. This is different from legal heir status and does not override a Will in all cases.
- KYC (Know Your Customer) — Banks are mandated by RBI and SEBI to verify your identity (Aadhaar, PAN) and address before opening an account or issuing a loan.
Benefits of Banking
- Safe custody of money. Cash at home carries theft risk. Bank deposits are insured up to ₹5 lakh per depositor per bank by DICGC, and the banking system itself is regulated by the RBI. For amounts above ₹5 lakh, spreading deposits across banks adds another layer of security.
- Interest income on deposits. Savings accounts currently pay around 2.7%–7% per annum depending on the bank, and FDs can pay 6.5%–9% for regular depositors (slightly higher for senior citizens). This grows idle money over time.
- Access to credit. A banking relationship — especially a salary account or maintained savings account — makes it easier to qualify for home loans, personal loans, and credit cards. Banks in India now use your average monthly balance and transaction history as informal creditworthiness signals.
- Digital payment infrastructure. UPI, NEFT, RTGS, IMPS, and net banking are all built on the banking backbone. Without a bank account, accessing these is impossible.
- Doorway to other financial products. Banks are the most accessible distribution point for mutual funds, insurance, government bonds, and sovereign gold bonds in India.
Risks & Limitations
- Interest rate risk on FDs. When you lock into an FD at 7%, and rates rise to 8%, you miss the higher return until your FD matures. Breaking an FD early usually attracts a 0.5%–1% penalty.
- Credit risk (for cooperative and small banks). Large scheduled commercial banks have failed rarely in India, but smaller cooperative banks have seen depositor distress — most recently in the PMC Bank case. Sticking to DICGC-insured limits and RBI-regulated banks reduces this risk.
- Inflation erosion. If your savings account pays 3% but inflation runs at 5%, your money loses real purchasing power. Using FDs or debt mutual funds instead of letting large sums sit idle in a savings account helps.
- Fraud and cyber risk. UPI fraud, phishing calls impersonating bank executives, and SIM-swap attacks are rising in India. Never share your OTP, CVV, or PIN with anyone — not even someone claiming to be from your bank.
- Hidden charges. Banks levy charges for non-maintenance of minimum balance, SMS alerts, ATM usage beyond the free limit, and cheque books. Read the schedule of charges before opening an account.
Important: If you receive a call asking you to “verify your account” or “claim a refund,” hang up. Your bank will never call asking for an OTP.
Frequently Asked Questions
What is a bank in simple terms?
A bank is a financial institution licensed by the RBI that keeps your money safe, pays you interest on deposits, and lends money to others at a higher rate.
The difference between these two rates is how a bank makes its income.
How do I find the nearest bank branch?
You can search “bank near me” on Google Maps, which shows branch locations, hours, and customer ratings. Most bank websites also have a branch and ATM locator.
For Bank of Baroda specifically, their website’s branch locator lets you search by city or PIN code.
What is a bank statement and how do I get one?
A bank statement is an official record of all transactions — credits, debits, and balances — in your account over a given period. You can download it through net banking,
the mobile app, request it at a branch, or write a bank statement application to your branch manager if you need an official stamped copy.
How do I close a bank account?
To close a bank account, visit your home branch with your passbook, debit card (cut into pieces), chequebook (unused leaves), and a filled bank account close application form.
Most banks also require a valid ID proof. Zero-balance accounts can typically be closed online or via a written request.
Ensure there are no standing instructions or auto-debits linked to the account before applying.
What is a bank guarantee?
A bank guarantee (BG) is a commitment by the bank that it will pay a specific amount to a beneficiary if the account holder fails to meet a contractual obligation.
It’s widely used in government tenders, construction contracts, and international trade.
The bank charges a commission (typically 1%–2% per annum of the guarantee amount) for issuing it.
Which bank offers the highest FD interest rates in India?
As of mid-2025, small finance banks like AU Small Finance Bank, Suryoday Small Finance Bank, and Unity Small Finance Bank offer some of the highest FD rates — in the range of 8%–9.5% for various tenures.
Among large private banks, HDFC and ICICI offer around 7%–7.5%. Rates change frequently; always check the bank’s website directly.
Senior citizens typically earn 0.25%–0.5% extra.
What is the Bank for International Settlements (BIS)?
The Bank for International Settlements is an international financial institution based in Basel, Switzerland, that serves as a bank for central banks.
It facilitates cooperation among central banks globally, conducts economic research, and sets global banking standards — such as the Basel III capital adequacy norms that Indian banks must follow.
How do I write a bank statement application?
A bank statement application is a simple written or typed request addressed to the Branch Manager of your bank.
Include: your name, account number, the period for which you need the statement, and your contact details. Sign and date it.
If you need it for a visa or loan, mention the purpose so the bank can stamp and attest it appropriately.
Many banks now allow you to request this digitally through their app.
