A salaried customer in Noida has banked with the same lender since her first job. Her salary lands there, the home loan EMI leaves from there, and the bank’s app sits on the second screen of her phone. Ask whether she loves the bank and she laughs. Ask whether she would move and she says the paperwork is not worth it. Most retail bank brand plans treat that answer as loyalty. It is inertia, and inertia is the first thing a competitor with a better loan offer takes away.
Customer loyalty in banking is earned at regulated moments, not in campaigns
Our position is simple. A retail bank should stop chasing brand love as a goal and start designing the few moments where a customer decides whether the bank is on their side. Those moments are not in the advertising. They sit in the loan paperwork, the fee line, the app error and the complaint reply, and in India most of them are already governed by the Reserve Bank of India (RBI).
Start with a definition, because the word is used loosely. Loyalty, for a bank, is a customer choosing to bring more of their money to you when a rival is one tap away. Staying put because moving is a chore is something else. Both show up as “retained customers” in a dashboard, and only one of them survives a better offer.
The best public evidence on this is old but still instructive. Bain & Company’s 2013 global study of retail banking loyalty, a consultancy survey of about 190,200 consumers in 27 countries including India, found that banks formed new primary relationships at about 3% a year in developed markets and about 6% in developing ones. Only 2.5% of developed-market respondents had switched primary bank in the past year. People rarely leave. That is the inertia most banks mistake for affection.
The same study found that in the US about three-fifths of switchers left over things such as high fees and poor service, and less than one-fifth left to take a better offer. Read that as a design brief. Customers leave over the moments a bank controls, and they seldom leave because a rival ran a warmer film. The money that decides customer loyalty in banking is spent, or not spent, on those moments.
We read that as the core of the argument. A brand campaign can make a bank familiar. It cannot make the bank trusted if the next statement carries a charge nobody explained. Trust is built or lost in the product, and the product is where the regulator already sets the rules.
What do retail banks do now to build loyalty?
To be fair to current practice, most retail bank marketing teams are not naive about loyalty. They run a familiar playbook, and parts of it work. The typical plan has five pieces.
- The emotional brand film. A festive or life-stage story that places the bank beside a family milestone. It builds recall and gives the brand a tone of voice.
- Rewards and cashback. Card points, partner offers and fee waivers that pay customers to use the bank more. They lift activity, and they stop working when the offer ends.
- Net Promoter Score tracking. A survey after key interactions asking how likely the customer is to recommend the bank. It gives leadership a single number to watch.
- Relationship managers for valued customers. A named person for premium and wealth customers. This is the one piece that reliably builds attachment, and it does not scale to the mass base.
- App and website redesigns. A cleaner interface, often launched with a campaign. Good for usability, and invisible to customers whose problem was a charge or a rejected claim.
Some banks go further and rebrand. India has a long record of bank identity changes, which we traced in our history of bank rebranding in India since Axis in 2007. A rebrand can reset perception. It cannot reset a customer’s last bad experience with a loan statement.
None of these pieces is wrong. The trouble is the order. Most budgets fund the film and the rewards first and leave the loan documents, the fee language and the complaint letters to operations and legal, with no brand input at all. Those are the pages customers actually remember.

Why does the brand-love model break for a regulated retail bank?
The brand-love model breaks because a regulated bank’s most memorable moments are written under rules, by teams the brand never briefs. The evidence for where customers feel let down is public, and it points away from advertising.
RBI publishes an annual report on its ombudsman scheme. Its Annual Report of Ombudsman Scheme, 2024-25, released on 1 December 2025, records 13,34,244 complaints received under the Reserve Bank Integrated Ombudsman Scheme in 2024-25, up 13.55% from 11,75,075 the year before. Of the 2,96,321 complaints received at the ombudsman offices, 81.53%, or 2,41,601, were against banks.
The categories matter more than the totals. Against banks, the largest groups in 2024-25 were loans and advances at 52,427, deposit accounts at 49,833, mobile and electronic banking at 46,700, and credit cards at 41,457, according to the same RBI report. Each of those is a product moment. Not one is a campaign moment. The scheme expects a customer to complain to the bank first, so most of these complaints mark a failed brand moment as well as a service failure.
Now set that beside what RBI asks banks to promise. RBI’s Charter of Customer Rights, released on 3 December 2014, sets out five rights: fair treatment; transparency, fair and honest dealing; suitability; privacy; and grievance redress and compensation. Scheduled commercial banks were expected to adopt a board-approved policy built on them. Read as a brand brief, that charter is a better loyalty strategy than most agency decks, and it already has board sign-off.
The gap is in execution. The brand team writes “we are with you” for the film, while the loan team sends a Key Facts Statement in a dense table, and the complaints team sends a reply drafted to limit liability. The customer hears three voices from one bank. Only one of those voices was briefed by marketing, and it is the one the customer trusts least.
A bank’s loyalty is decided on the pages its regulator makes it write, not in the films its agency makes it fund.
What a regulator-driven loyalty decision looks like
Calling a brand plan “compliance-aware” means little until it shows the decision. Here is one, built from a rule every Indian lender now works under. RBI’s instructions on the Key Facts Statement for loans and advances, issued on 15 April 2024, require lenders to give retail and MSME term-loan borrowers a Key Facts Statement before the loan contract is executed, for loans sanctioned from 1 October 2024.
The RBI notification sets several details that are design decisions in disguise. The statement includes the Annual Percentage Rate (APR), which covers all charges the lender levies. Charges not listed in it cannot be levied later without the borrower’s explicit consent. The lender has to explain the statement and get the borrower’s acknowledgement. The borrower gets a validity window to agree to the terms, of at least three working days for loans with a tenor of seven days or more. This is general guidance, not legal advice; your compliance team decides how the rule applies to your products.
Most lenders treat that as a document to attach. A loyalty-minded bank would treat it as the most important screen in the loan journey. In practice, that means four decisions.
- Show the APR on the first view of the statement, in the same type size as the EMI, with a one-line plain explanation of what it includes.
- Place the Key Facts Statement screen before the e-sign screen in the digital journey, as its own step with its own acknowledgement, and never as a link inside the consent checkbox.
- Present the review window as a promise in the bank’s own voice: the customer has time to read and decide, and the terms will hold while they do.
- List every charge in the statement in the same words the customer will later see on the account statement, so the fee line never surprises anyone.
None of these steps breaks the rule. Each one turns a mandatory disclosure into evidence that the bank deals fairly, which is the right the charter names. That is a loyalty asset no film can buy.
The same logic applies when a bank sells insurance. Under IRDAI’s 2024 regulations on protection of policyholders’ interests, an advertisement issued through a distribution channel needs the insurer’s written approval before issue, and every insurer’s advertisement has to show its registered name with its trade name or logo prominently. So a bank’s loyalty email that promotes a partner term plan carries two lockups and needs the insurer’s sign-off. Build that approval into the campaign calendar from day one. The bank’s brand architecture has to plan for the partner’s name on the page too, which we cover in our note on brand architecture for a bank with multiple products.
| Moment | Current practice | Proposed practice |
|---|---|---|
| Brand promise | Written for the campaign by the agency | Written against the RBI customer rights charter and tested on product pages first |
| Key Facts Statement | A legal attachment, styled by operations | A designed screen before e-sign, APR first, charges in statement language |
| Charges and fees | Listed on a schedule page few customers find | Named in the same words in the Key Facts Statement, app and statement |
| Complaint reply | Drafted to limit liability, with no brand review | Templates reviewed for tone by brand and compliance together |
| Bancassurance mailers | Approved late, lockup fixed at the end | Insurer approval and dual lockup planned in the calendar from the brief |
| Loyalty measure | Net Promoter Score and campaign recall | Voluntary behaviour: salary moved in, a second product taken without an incentive |
The strongest counter-argument: inertia pays, so why fix it?
The best case against our view is commercial. If customers rarely switch, a bank can earn well from a passive base. Fixing complaint letters and redesigning a Key Facts Statement costs money and wins no awards, while a festive film gets noticed by the board. Why spend on loyalty when inertia already keeps the deposits in place?
There is a second, fairer version of the objection. Emotional brand work does matter at the point of first choice. A young customer opening a first account, or a family picking a home-loan lender, often has no product experience to go on. Familiarity and warmth help a bank make the shortlist. We agree, and we would not tell a bank to stop brand advertising.
Our answer is that inertia is a weak moat that is getting weaker. The ombudsman numbers show complaints rising, and each complaint is a customer who has stopped being passive. Bain’s 2013 data showed that US switchers mostly left over fees and service. And on UPI a customer can pay from their bank account through an app the bank does not own, so the bank’s own screen can drop out of daily life. A bank that relies on paperwork to hold customers is one competitor offer away from finding out how thin that hold was.
The fair conclusion is a matter of order. Brand advertising earns the first look. The regulated moments decide whether the customer stays by choice. Most banks fund the first and neglect the second, and that is the imbalance we would correct.
What should a retail bank do instead, starting Monday?
A marketing head does not need a new strategy to start. The work begins with documents the bank already has. Here is the sequence we would follow.
- Pull last year’s internal complaint categories and set them beside the RBI ombudsman categories for banks. Where they overlap, you have found your loyalty problems, ranked by volume.
- Collect the five documents customers keep: the Key Facts Statement, the welcome letter, the charges page, the top complaint reply and the account statement. Read them in one sitting as a customer would.
- Write the brand’s tone rules against those documents before the next campaign brief. If a rule cannot survive a loan statement, it is a slogan.
- Put a brand reviewer in the approval chain for complaint templates and loan journeys, alongside compliance. Agree a turnaround so the review does not stall operations.
- Change the loyalty metric. Keep Net Promoter Score, and add voluntary signals such as salary accounts moved in and second products taken without a reward attached.
- Plan partner approvals early. Any loyalty mailer that carries insurance or investment products needs the partner’s sign-off and its own disclosures, so give it its own line in the calendar.
For a bank that wants this inside a wider plan, our brand strategy work starts from the same documents. The aim is a brand that sounds the same in the film, the app and the complaint letter.
What to tell your CFO: the first phase costs a review of existing documents and templates, with no media spend. The metric tied to revenue is voluntary product take-up among existing customers, tracked for two quarters. The stop rule is simple: if complaint volumes in the redesigned categories and voluntary take-up both stay flat after two quarters, the bank returns the budget to campaigns. This framing is ours, offered as a planning aid and not as a forecast.
What would change our view on customer loyalty in banking?
A position is only useful if it says what would overturn it. Three kinds of evidence would make us rethink.
The first is a sourced Indian study showing that customers move their primary bank relationship in response to brand advertising, at a rate that beats the effect of fees and service. We have not seen one. If a regulator, an industry body or a bank’s own published research showed it, we would weigh campaigns more heavily.
The second is evidence that the regulated moments do not move behaviour: that banks which redesign their Key Facts Statements and complaint replies see no change in complaints or product take-up. That would mean the documents matter less than we argue, and the money belongs somewhere else.
The third is a change in the rules. If RBI made switching a primary bank account as easy as porting a mobile number, inertia would vanish and every bank would compete on experience. In that world our argument gets stronger, and the banks that started early would be the ones with something to show.
Until then, the case is plain. A retail bank that wants customers to stay by choice should start with the pages its regulator already makes it write, and make those pages sound like the bank it claims to be.
People also ask
What is customer loyalty in banking?
Customer loyalty in banking is a customer choosing to keep and grow their relationship with a bank when a competitor is easy to reach. It differs from inertia, where the customer stays because moving feels like too much work. Loyal customers bring salary accounts, loans and second products by choice.
Why do customers switch banks in India?
Public data on Indian switching is thin, but RBI’s ombudsman report for 2024-25 shows bank complaints concentrated in loans, deposit accounts, digital banking and credit cards. Bain’s 2013 study found that most US switchers left over fees and poor service. Both point to product moments, not advertising, as the trigger.
Does a Key Facts Statement affect brand trust?
Yes, because it is one of the few documents a borrower reads closely before signing. RBI’s rules require it before the loan contract, with the APR included and no unlisted charges later without consent. A clear, well-designed statement is direct evidence of fair dealing.
