JAIIB RBWM Module A: CASA Mobilisation & Onboarding Guide

JAIIB RBWM CASA mobilisation is one of the most scoreable parts of the entire JAIIB exam, because it tests something most candidates already live every working day at the branch: how a bank acquires, onboards and retains Current Account and Savings Account customers. If you can name the concepts the way the textbook does, this module quietly hands you marks.

CASA — Current Account / Savings Account — is the lifeblood of retail banking. Module A of the JAIIB Retail Banking & Wealth Management (RBWM) paper builds the foundation: deposit account types, the onboarding journey from KYC to first transaction, the tactics that lift CASA at a branch, the distribution channels deposits flow through, and the retention levers that keep those accounts alive. This guide walks through all of it in plain, banker-friendly English.

Why CASA matters — the conceptual foundation

Start with the "why", because every Module A question is really a test of this single idea. CASA deposits are the cheapest source of funding a bank has. Savings accounts pay only about 3-4% interest, current accounts pay nothing at all, while term deposits cost the bank roughly 6.5-7%+. That cost gap is the whole game.

Picture two banks. A bank with a 45% CASA ratio funds its lending far more cheaply than a peer sitting at 30%. Lower cost of funds means a wider net interest margin, which means more profit on the same loan book. This is why every branch in the country is pushed on CASA growth, fortnight after fortnight.

The exam loves to wrap this in a number. A typical line: "Bank X has total deposits of ₹5,000 crore including ₹1,500 crore CASA — what is its CASA ratio?" Divide 1,500 by 5,000 and multiply by 100 to get 30%. Master that one pattern and you have covered the formula in every disguise it appears.

Types of deposit accounts — the building blocks

Module A expects you to distinguish the deposit account families by who can open them, whether interest is paid, and what restrictions apply. Learn them as a set, not in isolation.

• Savings Bank (SB) account: for individuals (resident, NRI, minor), HUFs, trusts and charitable societies with restrictions. Cheque issuance is permitted, and interest is paid on a daily product basis. Minimum or average monthly balance requirements vary by product variant.
• Current Account (CA): for businesses, professionals, traders, firms and companies. No interest is paid. Designed for high-volume, unlimited transactions, with higher minimum balance requirements and charges for shortfall.
• Term / Fixed Deposit (FD): a fixed tenor (commonly 7 days to 10 years) at a fixed rate, with a penalty for premature withdrawal. Variants include flexi FD, sweep FD and the tax-saver FD that carries a 5-year lock-in and qualifies under Section 80C.
• Recurring Deposit (RD): a fixed monthly contribution over a fixed tenor, paying a maturity value at the end. Built for disciplined, habit-based savings.
• Basic Savings Bank Deposit Account (BSBDA): the financial-inclusion account with no minimum balance requirement, a RuPay debit card and a cap of 4 free withdrawals per month at non-home branches or ATMs. A genuinely "no-frills" product.
• NRI accounts: the trio of NRO (Non-Resident Ordinary), NRE (Non-Resident External) and FCNR (Foreign Currency Non-Resident), each with its own currency, repatriation rule and tax treatment.

SB vs CA vs FD vs BSBDA — a quick comparison

When the differences blur under exam pressure, this table is the fastest reset. Read it across, not down.

Customer onboarding — the operational flow

Onboarding is the journey from a prospect at the counter to a live, transacting account. The exam tests it as an ordered sequence, so learn the steps in order:

1. Application: the customer walks in or applies online; the form is filled and identity and address proof are collected.
2. KYC verification: Aadhaar e-KYC, DigiLocker, or wet-ink OVD verification. PAN is mandatory above the specified threshold.
3. Customer Acceptance Policy (CAP) check: the profile is vetted against the bank's CAP, and high-risk customer files are escalated.
4. Account issuance: an account number is allotted along with the welcome kit — chequebook, debit card and internet-banking credentials.
5. First transaction: the first credit (cash, cheque or NEFT) activates the account.
6. Cross-sell: at the welcome interaction the bank offers a credit card, insurance, a mutual fund SIP, a demat account or a locker.

Notice the two layers the paper probes: the regulatory KYC framework (which overlaps with PPB Module A) and the operational service flow that lives in RBWM Module A. To shore up the regulatory side, revise our JAIIB PPB Principles & Practices of Banking guide, which sits right next door to this syllabus.

CASA mobilisation tactics — what actually works

This is where Module A turns practical, and where working bankers have a real edge. These are the CASA mobilisation tactics that consistently lift balances at a branch:

• Salary tie-ups: the branch approaches local employers and offers a salary-account product — typically a premium SB with bundled benefits. Every new salaried employee adds an SB account plus a cross-sell opportunity.
• Corporate banking referrals: companies that already hold current accounts at the branch refer their employees into the salary scheme.
• RD / FD lead conversion: a customer opening an RD must have a linked SB account, so recurring-deposit acquisition doubles as a savings-account lever.
• Onboarding camps: a temporary counter at an apartment complex, college, factory canteen or trade fair drives volume acquisition in a single day.
• Digital outreach: online account opening through the bank's app or website — Tatkal SB accounts, video-KYC and e-KYC powered onboarding.
• Business Correspondent (BC) channel: in underserved areas, BC outlets onboard accounts on the bank's behalf.
• Cross-product hooks: home-loan, car-loan and MSME borrowers are each given a salary, OD or CC account as part of the relationship.

Want to see how these acquisition hooks lead naturally into wealth products? Our companion read on wealth management products — mutual funds, insurance and NPS shows where the cross-sell conversation goes after the account is opened.

Distribution channels — multi-channel banking

Module A also expects you to know the channels deposits and services move through. Each has a primary role:

• Branch banking — the legacy channel, still dominant for first-time customers and complex transactions.
• ATM channel — withdrawals, deposits, mini-statements and PIN changes.
• Internet banking — full-service, replacing a large share of branch transactions for digitally onboarded customers.
• Mobile banking — app-driven and UPI-integrated, the channel of choice for younger customers.
• BC channel — rural and semi-urban penetration through Business Correspondents.
• Call centre — service queries, complaint logging and soft cross-sell.
• Tele-marketing and DSAs — outbound campaigns and the primary route for loan products and credit cards.

Customer retention — the underrated scorer

Most candidates over-index on acquisition, but the paper also rewards retention. A customer who is acquired and then lost within six months is a loss-making customer, because the cost of onboarding never gets recovered. The retention levers worth memorising are:

• Service quality at every touchpoint — the foundation everything else sits on.
• Fast complaint resolution, escalating to the Banking Ombudsman framework where required.
• Relationship pricing — free DDs and chequebooks, fee waivers and preferential FD rates for premium customers.
• Loyalty programmes — reward points on debit and credit cards.
• Relationship Manager model — a dedicated point of contact for premium and HNI customers.

A 7-day study plan for Module A

Module A is compact, so a focused week is enough to make it a high-accuracy section. Here is a realistic plan that fits around a working day:

1. Days 1-2: Lock down the CASA concept and the ratio formula, and read the deposit account types until you can recite the SB / CA / FD / RD / BSBDA distinctions from memory.
2. Day 3: Master the NRO vs NRE vs FCNR comparison — this single distinction shows up almost every cycle.
3. Day 4: Walk the six-step onboarding flow and tie it to the KYC framework you revised in PPB.
4. Day 5: Internalise the mobilisation tactics and distribution channels — these reward simple recall.
5. Day 6: Attempt 20 Module A questions in a timed JAIIB mock test, then review every wrong answer.
6. Day 7: Reinforce vocabulary with the JAIIB matching games and re-attempt the mock to confirm 70%+.

CASA at a glance

Common mistakes to avoid

• Confusing the NRI account trio. Candidates routinely mix up which accounts are repatriable and which interest is taxable. Anchor it: NRE and FCNR interest is tax-free and repatriable; NRO interest is taxable in India.
• Forgetting that a current account pays no interest. It is easy to assume "account equals interest", but CA is deliberately zero-interest — that is exactly why it is prized CASA.
• Treating the onboarding steps as unordered. The CAP check sits after KYC, not before — order matters in sequence questions.
• Ignoring retention. Acquisition gets the attention, but retention questions are easy marks if you have learned the five levers.
• Over-memorising exact targets. The exam tests the CASA concept and formula, not a bank-specific percentage — focus your energy there.

Frequently Asked Questions

What is the CASA ratio and how is it calculated?

The CASA ratio measures how much of a bank's total deposits sit in low-cost Current and Savings Accounts. It is calculated as CASA deposits divided by total deposits, multiplied by 100. A higher ratio means cheaper funding and a healthier net interest margin, which is why banks chase it so hard.

Why is CASA called low-cost funding?

Savings accounts pay only about 3-4% interest and current accounts pay nothing, while term deposits cost a bank around 6.5-7% or more. Because CASA balances are so much cheaper to hold, every rupee shifted from term deposits into CASA widens the bank's lending margin. That is the entire commercial logic behind CASA mobilisation.

Can NRE and FCNR accounts earn interest?

Yes — both NRE and FCNR accounts earn interest that is fully repatriable, and NRE interest is exempt from Indian income tax. NRO accounts also earn interest, but that interest is taxable in India. This three-way distinction is a classic exam question pattern.

What is the difference between a BSBDA and a regular savings account?

A BSBDA has no minimum balance requirement, whereas a regular SB account often does. BSBDA also restricts free withdrawals to four per month and is designed for financial-inclusion segments, with Aadhaar-linked DBT receipts frequently flowing into these accounts.

Does RBWM Module A include Wealth Management?

Module A is primarily about retail banking foundations — deposit accounts, account types and customer onboarding. Wealth management topics such as investment advisory, asset allocation and financial planning are covered in later modules of the same paper. You can see the full breakdown on the JAIIB course page.
