Banking Operations and Terminology
KYC and anti-money-laundering
KYC (know your customer) is the bank's duty to identify and verify a customer, and the beneficial owner behind the account, before and during the relationship. It rests on the Prevention of Money-Laundering Act, 2002 and RBI's Master Direction on KYC (2016, amended since). The purpose is to stop accounts being used to hide the proceeds of crime; the process is called customer due diligence (CDD).
- Officially valid documents (OVD) listed in the Master Direction: passport, driving licence, proof of possession of Aadhaar number, voter's identity card, NREGA job card, and the letter issued by the National Population Register.
- Deemed OVD for address only: a recent utility bill (not more than two months old), property or municipal tax receipt, pension payment order, or an employer's accommodation letter; the customer must then give an OVD with the current address within three months.
- Small account for those without an OVD: credits up to ₹1 lakh in a year, withdrawals and transfers up to ₹10,000 a month, balance never above ₹50,000; it runs for 12 months, extendable by 12 more if the holder has applied for an OVD (as of October 2026, per the Master Direction).
- V-CIP (video-based customer identification process) allows face-to-face-equivalent identification by live video with facial recognition, when it meets the prescribed standards.
KYC is not a one-time act. Records are refreshed by periodic updation according to the customer's risk category: at least once in two years for high-risk, eight years for medium-risk and ten years for low-risk customers, counted from account opening or the last updation. The Central KYC Records Registry (CKYCR) stores the digital KYC record so that a customer verified once need not repeat the whole exercise at another institution.
Negotiable instruments, cheques and demand drafts
The Negotiable Instruments Act, 1881 recognises three negotiable instruments: the promissory note, the bill of exchange and the cheque. A cheque is a bill of exchange drawn on a specified banker and payable on demand. Three parties appear: the drawer (who signs and owns the account), the drawee (the bank) and the payee (who receives the money). Negotiable means transferable by delivery or by endorsement and delivery, so that the holder in due course gets a good title.
| Crossing | What it means |
|---|---|
| Open cheque | Can be encashed at the counter by the bearer |
| General crossing (two parallel lines) | Paid only through a bank account, never in cash at the counter |
| 'Account payee' crossing | The collecting banker should credit only the payee's account |
| Special crossing (a bank's name between the lines) | Payable only to that named bank |
Validity. Since 1 April 2012 RBI has told banks not to pay a cheque, draft or pay order presented more than three months after its date. A cheque presented after that is stale. A post-dated cheque carries a future date and cannot be paid before it; an ante-dated one carries an earlier date.
Dishonour. When a cheque is returned for insufficient funds or because the amount exceeds the arrangement with the bank, Section 138 makes it a criminal offence, but only if the steps run in order:
(1) the cheque is presented within its validity;
(2) it is returned unpaid;
(3) the payee sends a written demand within 30 days of learning of the return;
(4) the drawer fails to pay within 15 days of receiving the notice;
(5) the payee files a complaint within one month after that period ends. The penalty may be imprisonment up to two years, or a fine up to twice the cheque amount, or both.
A demand draft (DD) is issued by a bank on itself (drawn on one of its branches), against payment in advance, to a named payee at a named place. Because the bank has already received the money, a DD cannot bounce for want of funds in the buyer's account, which is why it is trusted for fees and deposits. Cheques are cleared today through the Cheque Truncation System (CTS): the physical cheque stops at the presenting bank and only its image and data travel; since the August 2025 circular, clearing runs as continuous clearing through the day instead of in two batches.
| Code | Structure | Used for |
|---|---|---|
| MICR | 9 digits: city (3), bank (3), branch (3) | Cheque clearing |
| IFSC | 11 characters: 4 letters for the bank, a zero, then 6 characters for the branch | NEFT and RTGS |
Loans, interest and non-performing assets
A term loan is repaid in instalments over a fixed period. A cash credit or overdraft is a revolving limit: interest is charged only on the amount actually drawn, on the daily balance. A loan is secured when backed by an asset and unsecured otherwise. The borrower's own contribution to the cost is the margin. The way the security is held differs by asset: pledge (movable goods, possession passes to the bank), hypothecation (movable goods, possession stays with the borrower) and mortgage (immovable property).
Interest on a reducing balance is charged each month on what is still owed. Worked example: a loan of ₹1,00,000 at 12% a year over 12 months has an EMI of about ₹8,885. Month 1 interest is 1% of ₹1,00,000 = ₹1,000, so ₹7,885 repays principal and the balance falls to ₹92,115. Month 2 interest is 1% of ₹92,115, about ₹921. Interest shrinks each month. A flat-rate quote charges interest on the original amount throughout: 10% flat on ₹1,00,000 for 2 years means ₹20,000 of interest and an EMI of ₹1,20,000 ÷ 24 = ₹5,000, which is equivalent to roughly 18% a year on a reducing balance.
Benchmarks. Floating loan rates have moved from the base rate (July 2010) to MCLR (April 2016) to external benchmarks for new floating-rate retail and micro and small enterprise loans from 1 October 2019: the policy repo rate or a Treasury-bill yield published by FBIL. An external-benchmark rate must reset at least once in three months, and when the spread is unchanged, a change in the benchmark passes through to the borrower's rate in full at the next reset.
Asset classification (as of October 2026, under RBI's consolidated Asset Classification, Provisioning and Income Recognition Directions in force at that date; RBI announced final new Directions on 27 April 2026, to take effect on 1 April 2027, so read this section as the position until then and check the current Directions). A term loan becomes a non-performing asset (NPA) when interest or an instalment is overdue for more than 90 days. An account overdue for 1 to 30 days is a special mention account SMA-0, 31 to 60 days SMA-1 and 61 to 90 days SMA-2; these are early-warning stages, not NPAs.
| NPA category | Test |
|---|---|
| Sub-standard | NPA for 12 months or less |
| Doubtful | Has stayed sub-standard for 12 months |
| Loss | Loss identified by the bank, auditors or RBI inspection; no time period needed |
Capital adequacy, Basel norms and deposit insurance
A bank lends out most of its deposits, so its own capital is the cushion that absorbs losses before depositors are hurt. Capital adequacy compares that cushion with the risk carried: CRAR = (eligible capital ÷ risk-weighted assets) × 100. Risk-weighted assets (RWA) weight each exposure by its riskiness, so a loan with a 50% weight counts for half its amount. The Basel Committee on Banking Supervision, hosted at the Bank for International Settlements in Basel, writes the standards: Basel I (1988) set a minimum capital ratio for credit risk, Basel II (2004) added three pillars (minimum capital, supervisory review, market discipline), and Basel III (after the 2008 crisis) raised the quality and quantity of capital and added a leverage ratio and liquidity standards (the LCR and NSFR).
| Indian Basel III minimum (as % of RWA) | Level |
|---|---|
| Common Equity Tier 1 (CET1) | 5.5% |
| Tier 1 capital (CET1 plus Additional Tier 1) | 7% |
| Total capital (CRAR) | 9% |
| Capital conservation buffer, held as CET1 | 2.5% |
| Total capital plus buffer | 11.5% |
Worked example. A bank has ₹800 crore of loans at 100% weight and ₹400 crore at 50% weight: RWA = 800 + 200 = ₹1,000 crore. With capital of ₹105 crore, CRAR = 10.5%. That clears the 9% minimum but is below 9% + 2.5% = 11.5%, so the bank is eating into its conservation buffer and faces curbs such as on dividends until it rebuilds. Ignoring the weights would give 105 ÷ 1,200 = 8.75%, a wrong and alarming figure.
Deposit insurance. The DICGC, a subsidiary of RBI, insures deposits up to ₹5 lakh per depositor per bank (principal and interest together, across savings, current, fixed and recurring accounts), a limit in force since 4 February 2020 (no later revision found as of October 2026). The cover is per bank, not per account: a person holding ₹3 lakh savings and ₹4 lakh FD in the same bank, in the same name, is insured for ₹5 lakh if it fails, while a separate ₹2 lakh deposit in another insured bank has its own cover.
Credit score, the ombudsman and customer protection
A credit information company (CIC) collects repayment records from lenders and turns them into a credit report and a credit score. India has four, regulated by RBI under the Credit Information Companies (Regulation) Act, 2005: TransUnion CIBIL, Equifax, Experian and CRIF High Mark. A CIBIL-type score runs from 300 to 900; higher means lower risk. Lenders have had to update data fortnightly since 1 January 2025 (RBI has been moving towards more frequent reporting, so treat the interval as dated), and each CIC must give an individual one free full credit report a year. Missed instalments, high card utilisation and many fresh loan enquiries pull a score down.
Grievance route. First complain to the bank. Only if it does not reply in 30 days, or the reply is unsatisfactory, does the customer go to the RBI Ombudsman under the Reserve Bank - Integrated Ombudsman Scheme, 2026, in force from 1 July 2026. It replaced the 2021 scheme, which had itself merged the Banking Ombudsman Scheme 2006, the NBFC Ombudsman Scheme 2018 and the Ombudsman Scheme for Digital Transactions 2019 under 'One Nation One Ombudsman'. As of October 2026 the complaint must reach the Ombudsman within 90 days of that period ending or of the entity's last reply, through the cms.rbi.org.in portal, by email or by post to the Centralised Receipt and Processing Centre (CRPC); it is free; and compensation can be up to ₹30 lakh for consequential loss plus up to ₹3 lakh for time, expense and harassment.
Lead bank scheme and core-banking vocabulary
The Lead Bank Scheme came out of the Gadgil Study Group (October 1969), which recommended an area approach, and the Nariman Committee; RBI introduced it in December 1969. Each district is allotted to one bank, the lead bank, which surveys the district's credit gaps, prepares the district credit plan and coordinates other banks. A Lead District Manager (LDM) heads the effort, and review runs through the Block Level Bankers' Committee, the District Consultative Committee (DCC) and the State Level Bankers' Committee (SLBC).
Core banking solution (CBS) keeps customer, account and transaction data in a centralised database that every branch, ATM and internet channel reads and updates in real time. That is what makes anywhere (any-branch) banking possible: a deposit at one branch is immediately visible at all others. A lien is the bank's right to hold a customer's asset as security until a debt is paid; marking a lien on an FD for a loan against that FD is a common example.
Key takeaways
- Banking is accepting deposits from the public to lend or invest; NRE is earned abroad and repatriable, NRO is Indian income and restricted.
- KYC rests on the PMLA 2002 and RBI's Master Direction; updation cycles run 2, 8 and 10 years for high, medium and low risk.
- A cheque is stale after three months; Section 138 needs the order: presentation, return, notice within 30 days, 15 days to pay, complaint within one month. A DD cannot bounce for want of funds.
- Reducing-balance interest falls each month; flat-rate quotes cost far more than they look. NPA means overdue for more than 90 days; sub-standard is 12 months or less, doubtful follows, loss is by identification.
- CRAR = capital ÷ RWA; Indian Basel III minimum 9% total, 7% Tier 1, 5.5% CET1, plus 2.5% buffer (11.5%), as of October 2026. DICGC covers ₹5 lakh per depositor per bank.
- Complain to the bank first; the RBI Ombudsman Scheme 2026 allows escalation after 30 days; the Lead Bank Scheme (1969) assigns each district to one bank.
Practice questions (17)
Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.
Under the Banking Regulation Act, 1949, which activity is at the core of the definition of 'banking'?
Show answer
Answer: B — Accepting public deposits for lending or investment, repayable on demand or otherwise and withdrawable by cheque or draft
Section 5(b) defines banking by deposit-taking for lending or investment, with deposits repayable on demand or otherwise and withdrawable by cheque, draft or order. Note issue and government debt management are RBI functions, deposit insurance is DICGC's and capital norms are RBI regulation, so they are not the defining activity of banking.A resident-turned-NRI wants to park the monthly rent that his Indian flat earns in a rupee account in India. Which account is meant for income earned in India?
Show answer
Answer: C — NRO account, because it holds income earned in India and its repatriation is restricted
Income earned in India, such as rent, belongs in an NRO account, whose balances can be repatriated abroad only within a limit and under conditions. NRE is the tempting choice but it is funded from foreign earnings and is freely repatriable; FCNR(B) holds foreign currency.A customer is classified as high-risk and her KYC was last updated in March 2024. By the Master Direction's periodic-updation cycle (2, 8 and 10 years for high, medium and low risk), when is the next updation due at the latest?
Show answer
Answer: D — March 2026, because the gap for a high-risk customer is at most two years
High-risk customers are updated at least once in two years, so March 2024 plus two years gives March 2026. Eight years (March 2032) is the medium-risk gap and ten years (March 2034) the low-risk gap; no annual cycle is prescribed.A cheque has two parallel lines drawn across its face and the words 'Account Payee' written between them. Which statement is correct?
Show answer
Answer: A — The paying bank will not pay cash at the counter and the collecting banker should credit only the payee
Crossing generally means payment only through a bank account, and the 'account payee' words direct the collecting banker to credit only the payee. A bearer cannot encash it over the counter. Crossing restricts collection, not validity, and the validity period is three months, not six.A cheque dated 10 June 2026 is presented to the drawee bank on 20 September 2026. Under RBI's validity rule for cheques, what is the position?
Show answer
Answer: B — It is stale and will not be paid, as it was presented after three months
The three-month window from 10 June ended on 10 September, so a presentation on 20 September is stale and the bank will not pay. Six months was the earlier rule and is the tempting wrong answer. Nothing in the rule lets a telephone confirmation revive a stale cheque.Which sequence of periods correctly describes the steps a payee must follow after a cheque is returned for insufficient funds, before a complaint under Section 138 of the Negotiable Instruments Act?
Show answer
Answer: C — Notice within 30 days of learning of the return; the drawer gets 15 days; complaint within one month after
The sequence is: demand notice within 30 days of learning of the return, 15 days for the drawer to pay after receiving it, then a complaint within one month. Swapping 30 and 15, as the notice-in-15-days sequence does, is the usual trap.Why is a demand draft regarded as safer for the payee than an ordinary personal cheque?
Show answer
Answer: D — Because the bank issues it after receiving the money, so it cannot bounce for lack of funds in the buyer's account
A DD is issued by a bank against advance payment, so the payee relies on the bank, not on the buyer's balance. The other options are false: a DD is payable at a specified branch, is also subject to the three-month presentment rule, and is covered by the Negotiable Instruments Act.Which description of the two bank-identification codes is correct?
Show answer
Answer: A — IFSC has 11 characters, the fifth being zero, and MICR has 9 digits for city, bank and branch
IFSC is an 11-character code (four letters for the bank, a zero, six characters for the branch) used for NEFT and RTGS; MICR is a 9-digit code (city, bank, branch) printed on cheques for clearing. The option that gives IFSC nine digits swaps the two, which is the usual exam trap.A ₹1,00,000 loan at 12% a year, reducing balance, is repaid in 12 monthly EMIs of ₹8,885. Month 1 interest is 1% of the loan. Which is closest to the interest part of the month-2 EMI?
Show answer
Answer: B — ₹921, as the balance after month 1 is ₹92,115
Month 1: interest ₹1,000, principal ₹8,885 - ₹1,000 = ₹7,885, balance ₹1,00,000 - ₹7,885 = ₹92,115. Month 2 interest = 1% of ₹92,115, about ₹921. The ₹1,000 answer treats the loan as flat-rate, which it is not.A lender quotes '10% flat' on ₹1,00,000 for 2 years, giving a monthly instalment of ₹5,000. How does this compare with a 10% reducing-balance loan of the same size and term?
Show answer
Answer: C — It is dearer, because interest stays on the full original amount throughout
Under the flat quote the total interest is ₹20,000 regardless of repayments, which equals about 18% a year on a reducing balance. A reducing-balance loan charges interest only on what is still owed, so the same headline percentage costs less.In a non-leap year a term-loan instalment due on 1 January is unpaid. How should the account be classified on 20 March (as of October 2026 norms, with SMA-1 for 31-60 and SMA-2 for 61-90 days overdue)?
Show answer
Answer: D — SMA-2, because it is 78 days overdue, which is within 61 to 90 days
From 1 January to 20 March in a non-leap year is 31 + 28 + 19 = 78 days overdue. That is within 61 to 90 days, so SMA-2. It is not NPA, which needs more than 90 days, and doubtful is a stage of an NPA only after 12 months as sub-standard.A borrower's account has been a non-performing asset for 14 months, with no loss formally identified yet. Under RBI's asset classification it is a
Show answer
Answer: A — doubtful asset, as it has stayed sub-standard for the full 12 months
An NPA is sub-standard for 12 months or less; after 12 months in that category it is doubtful. Loss needs the loss to be identified by the bank, auditors or RBI inspection, not merely age. Special mention accounts are pre-NPA stages (up to 90 days overdue).Which Basel accord, issued in 1988, first set a minimum capital requirement for banks against credit risk?
Show answer
Answer: B — Basel I
Basel I (1988) was the first accord to set a minimum capital ratio for credit risk. Basel II (2004) added the three pillars and Basel III (after the 2008 crisis) tightened capital and added leverage and liquidity standards, so neither was issued in 1988.A bank has ₹800 crore of exposures at 100% risk weight and ₹400 crore at 50% risk weight, and total eligible capital of ₹105 crore. Against Indian Basel III minimums (total 9%, plus 2.5% conservation buffer, as of October 2026), which statement is correct?
Show answer
Answer: C — CRAR is 10.5%, above 9% but below 11.5%, so the buffer is being used
RWA = 800 × 100% + 400 × 50% = ₹1,000 crore, so CRAR = 105 ÷ 1,000 = 10.5%. That is above the 9% minimum but below 11.5%. Dividing by the unweighted 1,200 gives 8.75%, which wrongly suggests a breach of the minimum.Anil holds, all in his own single name, ₹3 lakh in savings and ₹4 lakh in an FD at Bank X, and ₹2 lakh in an FD at Bank Y. Both are insured banks. If Bank X fails, how much of his Bank X money is insured, and what is his total insured across both banks if only X fails? (DICGC limit of ₹5 lakh per depositor per bank, as of October 2026.)
Show answer
Answer: D — ₹5 lakh at Bank X, and ₹7 lakh in total, as Bank Y is untouched
DICGC cover is ₹5 lakh per depositor per bank across account types, so Bank X's ₹7 lakh is insured only to ₹5 lakh. Bank Y did not fail, so its ₹2 lakh remains with Bank Y in full; the total secured is ₹5 lakh + ₹2 lakh = ₹7 lakh. The limit is per bank, not once overall.A bank has not replied to a customer's written complaint for 30 days. Under the RBI Integrated Ombudsman Scheme, 2026 (in force from 1 July 2026), what may the customer do?
Show answer
Answer: A — Approach the Ombudsman directly through cms.rbi.org.in or the CRPC within 90 days
After the 30-day reply period, or on an unsatisfactory reply, the customer can file with the RBI Ombudsman within 90 days, online, by email or by post to the CRPC. The service is free and the complaint is addressed directly to the RBI Ombudsman. The filing fee, the one-year wait and the compulsory advocate in the other options are not part of the scheme.The Lead Bank Scheme, introduced in December 1969 on the basis of the area approach recommended by the Gadgil Study Group, does which of the following?
Show answer
Answer: B — Gives each district to one bank that prepares its credit plan and coordinates others
The scheme allots districts, not states, to lead banks, which survey credit gaps, prepare the district credit plan and coordinate through the DCC and SLBC. It does not fix interest rates or give anyone a monopoly on branches.
