Customer experience in banking: the rare moments that decide whether customers trust you

Customer experience in banking is everything a customer goes through with a bank. It runs from opening the account and paying with the app to the fraud alert, the mortgage, the death of a parent and the complaint that follows a mistake. It is decided in a handful of rare, high-stakes moments where trust is won or lost, and spent in small errors in between. Satisfaction with US retail banks rose to 657 out of 1,000 this year, yet the average customer now holds three deposit accounts at different institutions and 20% moved money away from their primary bank in the past three months. Banks measure the satisfaction and read it as loyalty. The money is already leaving. This article maps where bank CX breaks, using complaint data from regulators in four countries. It names the five moments that decide trust and shows what to measure at each one.

Key takeaways:

• Fraud is now the main reason customers escalate: half of current account complaints at the UK Financial Ombudsman, a record 2,422 admissible files at the Belgian ombudsman, and 516 million euros of manipulation fraud in France, 42% of all payment fraud.
• Satisfaction holds while the relationship leaks. The average US bank customer keeps three deposit accounts, and one in five moved money away from their primary bank in the past three months (J.D. Power, 2026).
• Trust ranks first among the seven drivers of bank satisfaction, ahead of people, products and digital channels. Only 39% of UK adults are confident in the financial services industry.
• Five moments decide trust: opening the account, the fraud alert, the mortgage, the death in the family and the complaint. Each deserves its own measurement, separate from the everyday app experience.
• Visible security builds trust, small errors spend it faster than in any other sector, and an app store rating measures neither. The relationship is in the open comments.

What customer experience in banking means

Customer experience in banking is the accumulated impression a customer forms of a bank across every contact, from the first account to the last transfer out. Three things set it apart from other sectors. The product is a promise: the bank holds the customer's money and the customer has to believe it will be there, intact and reachable, tomorrow. The everyday contact is almost entirely digital. In Belgium, 89% of people bank through the app and 85% through the PC, and two in three use the app at least weekly. Cash withdrawals fell below 120 million in 2025, from 300 million in 2013. And the moments that make or break the relationship are rare and heavy: a mortgage, a fraud, a death, a dispute.

Those two layers pull in different directions. The daily layer rewards speed and invisibility. The rare layer rewards a human who knows what to do. French consumers say so themselves. 78% describe the ideal bank as one that lets them use online services or a branch depending on the need; 9% want digital only. The American Customer Satisfaction Index makes the same point from the other side. US banks held at 80 in its 2026 study, and the biggest gains came from branch and ATM locations and in-branch transaction speed. That is the physical layer the industry has spent a decade thinning.

Why bank satisfaction numbers hide the risk

Banks rarely lose customers in one move. They lose share of wallet in small, quiet transfers. J.D. Power's 2026 study of 107,059 US retail customers found satisfaction up two points, with sharp declines in the second half of the year across phone, branch, online and automated channels. The 20% who moved money away from their primary bank were 17% a year earlier, and among customers under 40 the share is 23%. Jennifer White, senior director of financial services intelligence at J.D. Power, calls it soft switching. Cracks at key points, she says, "are opening the door to quietly establish new accounts with other institutions and gradually shift funds away from their primary bank."

Hard switching exists too, and it has become easy. The UK Current Account Switch Service recorded over one million switches in 2025, with 350,114 in the last quarter alone. Belgium's bank switching service handled 111,745 requests in 2025, and 45,178 customers moved their savings account with it. Nothing about the process holds customers in place any more. What holds them is the absence of a reason to leave, which is a thinner thing than loyalty.

The spread between banks shows how much room there is. In the CMA's independent survey of 17 British current account providers, 79% of the top provider's customers would recommend it to friends and family; 48% of the bottom provider's would. Monzo, which tops that ranking, reports an NPS of 76 against an industry average of 30, and 79% of its 15.2 million customers joined through word of mouth. ING states its ambition as a number one NPS in every retail market and reported holding that position in five out of ten in 2025. Benchmarks for the headline number are in our guide to what a good NPS score is. The useful question is which moments produced it.

Where bank CX breaks: a complaint map from four countries

Ombudsmen and regulators publish what customers escalate, and in banking one theme has taken over the top of every list.

Sources: Ombudsfin annual report 2025; Kifid 2025 and Kifid trends; ASF mediator 2025 and Banque de France OSMP 2025; Financial Ombudsman 2025/26 and FCA complaints data H1 2026.

Two details matter for a CX lead. First, the fraud victim is the customer least likely to get a resolution. Ombudsfin's mediation succeeded in 82.5% of founded cases overall, but in 58.3% of fraud cases and 8.7% of fraudulent credit cases, against more than 95% for everything else. Second, the volume keeps growing at the front line. In the UK, current accounts became the most complained about product at the Ombudsman in the second quarter of 2026, with fraud and scams half of the cases. The bank did not steal the money. The customer still judges the bank on what happened next.

The five moments that decide trust, and what to measure at each

Most of a bank's feedback comes from routine contacts, and most of its trust is decided elsewhere. Five moments recur in the regulators' files. Each one needs its own transactional survey close to the event, because an annual relationship score averages them away.

1. Opening the account

Many of the maps banks draw of their onboarding describe the bank's process: application, credit scoring, underwriting, activation. Rewrite every stage as something the customer would say out loud ("I still cannot pay with it", "they asked for the same document twice") and the real friction appears. Onboarding is also the moment a switcher arrives with a reason, and the first weeks decide whether the reason survives. J.D. Power finds that the most satisfying banks treat routine experiences such as alerts, transfers and fees as chances to reinforce clarity and confidence. Measure the first 30 days: time to a working card and app, drop-off between application and first payment, an effort score at day 7 and one open question. The open answers name the step that stalls.

2. The fraud alert

The fraud alert is the moment the customer discovers what the bank is worth. In the UK, authorised push payment fraud rose 19% to 576.4 million pounds across 248,070 cases in 2025, and banks reimbursed 61% of the losses. Two thirds of those scams started online and 17% on the phone, which is also how the bank tries to reach the customer. In the Netherlands, Kifid still receives dramatic stories about bank helpdesk fraud, where the criminal poses as the bank itself. Measure two contacts: the one after a blocked card or a fraud warning, and the one after a reimbursement decision, with an effort score and a free text field. Read the refused cases with particular care. They are the ones that end up at the ombudsman.

3. The mortgage

A mortgage is the largest decision most customers ever make with a bank, and they make it rarely. Kifid notes that people trust their mortgage adviser almost blindly, which makes the adviser's duty of care the whole experience. Measure three points: after the offer, after the signing and three months into repayment, when the first direct debit and the first statement have arrived. One question each, one open field. Do not start a programme here. The mortgage overhaul takes years; the account-opening pilot takes a quarter.

4. The death in the family

A bereavement is the rarest moment and the one that is remembered longest. The FCA reviewed how British banks handle bereavement and power of attorney. In some cases staff did not acknowledge that customers were noticeably distressed and upset. Representatives went through extended periods unable to access funds to pay essential bills. Customers had to repeat information to different staff or saw their case lost in the firm's systems. The review also found what works: dedicated bereavement teams, and one firm with video calls to a specialist adviser. Measure it with restraint, a short survey to the representative after the file closes, and read every comment.

5. The complaint

A complaint is a second chance that the bank asked for. The numbers show how often it is needed: firms in the UK logged 525,653 current account complaints in six months. Measure after closure, with an effort question and one more: did we explain the outcome in a way you understood. A complaint that is closed and not understood is a soft switch in waiting.

Visible security builds trust, small errors spend it

Trust is the first of the seven drivers in J.D. Power's model, ahead of people, products, convenience, savings, digital channels and problem resolution. It is also scarce. In the FCA's Financial Lives survey, 39% of UK adults had confidence in the financial services industry and 36% thought most firms are honest and transparent. Banks were the most trusted institutions, with 21% expressing high trust and 40% low trust. The Dutch central bank measured trust in banks rising from 56% to 62% in 2026. Trust in the payment system, at 74%, comes mostly from everyday experience: payments that go through quickly and without problems. The same households worry about cyberattacks and outages.

Security the customer can see and understand builds that trust. Belgium's itsme app, founded in 2017 by the banks and the telecom operators, has more than 8 million users. It handled 594 million identifications in 2025, 25% more than the year before. The name check on transfers, which warns when a name and an account number do not match, is the same idea: protection that happens in front of the customer. Each one is a deposit.

Small errors are the withdrawals, and in banking they cost more than elsewhere because the customer reads them as a sign about the money. A duplicate debit, a card declined abroad, an alert that fires late, a fee nobody explained. Steven Van Belleghem described the shift banks need on our CX Matters podcast: from selling products to being a partner in life. Starting a conversation with "how can we contribute to the success of this entrepreneur" is different from "do you need a loan? I have an investment opportunity for you". He also named the fight ahead: transactional perfection on one side, a feeling of belonging on the other, and cheap alternatives as the third player. The effort of finding one is dropping to zero. A bank that misses the small things has already lost the first fight.

Why the app store rating is not the relationship

Banks watch their app ratings closely, and the ratings are good. The app is the daily layer, and the daily layer works. The relationship is decided in the layer the rating never sees. In J.D. Power's model, digital channels rank sixth of seven dimensions in importance, behind trust, people and account offerings. The star rating measures whether the app opened this morning. The open comments measure whether the customer would trust the bank with a fraud, a mortgage or a parent's estate.

That is why the real story is in what customers write, in the app review, the survey comment, the chat and the call after a fraud alert. Our guide to customer feedback analysis covers how to read that text at volume. Sentiment per topic, rather than one score per comment, makes "the app is great, the fraud team was unreachable" count as two signals. The second one predicts the money moving.

How to measure bank CX so it changes something

Bank CX measurement works in three layers, and the banks that steer on it put at least one on the scoreboard, which is where ING and Monzo put their NPS. The scoreboard matters because 48% of companies never calculate the financial impact of CX, as a 2026 study found. A number nobody owns changes nothing.

The first layer is the relationship score at brand level, a few times a year: the number the annual report quotes. Then comes the transactional layer, a short survey after each of the five moments above, with an effort or satisfaction question and one open field. Underneath both sits the open text itself, at bank volume. It includes the feedback customers never put in a survey: the calls, chats and emails about blocked cards, missing payments and documents requested twice.

Two capabilities carry most of the weight. Key driver analysis turns thousands of comments into a ranked list of what moves the score. The fraud team's call-back time or the onboarding document loop then shows up as a driver with a weight, rather than an anecdote in a steering committee. Forward-looking alerts catch the sentiment shift on a theme, a new scam pattern or a broken app release, before it becomes a complaint category. Customer interactions bring the unsolicited feedback from calls and chats into the same view as the surveys. That is how Hello Customer is set up for banks and insurers, with the compliance perimeter the sector needs. If you are choosing software, our comparisons of CX platforms for banking and feedback software for financial services set out the criteria. Telecom operators face a close cousin of this problem; our guide to customer experience in telecommunications shows the same method applied to bills and outages.

A 90-day start for a bank CX lead

Think big, act small. The programme does not have to start with the whole lifecycle, and it should not start with the mortgage. Pick the account opening: high impact, real friction, fixable in a quarter.

1. Rewrite the onboarding map in the customer's words. Every stage becomes a sentence a customer would say, and the pain points surface before any survey is sent.
2. Define one question set: an effort score and one open field at day 7, and again at day 30 once the card, the app and the first payment have happened.
3. Run four weeks as a baseline and read every open answer, including the app store reviews and the chats from the same cohort.
4. Rank the drivers. The ranked list is the to-do list for operations, in their language: document requests, activation delays, unclear fees.
5. Fix the top driver and call back every detractor within 48 hours. Record what was promised and whether it was kept.
6. Tell the customers who gave feedback what changed. In banking that message is also a security signal: the bank listens and acts in the open.
7. Report two numbers to finance at day 90: the effort score per step, and the share of the surveyed cohort that made the new account their primary one.

Then add the fraud alert, the complaint, the mortgage and the bereavement, one at a time, each with its own survey and its own owner.

Frequently asked questions

What is customer experience in banking?

Customer experience in banking is the overall impression a customer forms of a bank across every contact: the account opening, the app, the fraud alert, the mortgage, the bereavement and the complaint. The daily contact is digital and the heavy moments are rare, so the experience is decided mostly by how those rare moments are handled. Regulators in Belgium, the Netherlands, France and the UK all report fraud as the main reason customers escalate.

Why is trust the most important driver of customer experience in banking?

Trust ranks first among the seven drivers of retail bank satisfaction in J.D. Power's 2026 study, ahead of people, products, convenience and digital channels. A bank holds the customer's money, so every error is read as a sign about the money itself. Visible security, such as a digital identity app or a name check on transfers, builds trust; late alerts, unexplained fees and poor fraud handling spend it.

How do banks measure customer experience?

In three layers. A relationship score at brand level a few times a year; a transactional survey after each high-stakes moment (account opening, fraud alert, mortgage, bereavement, complaint) with an effort or satisfaction question and one open field; and analysis of the open text from surveys, calls, chats and reviews. Key driver analysis then ranks which topics move the score, so the bank fixes the heaviest driver first.

What is soft switching in banking?

Soft switching is when a customer keeps the account but moves the money. J.D. Power found in 2026 that the average US retail bank customer holds three deposit accounts at different institutions. 20% moved money away from their primary bank within the past three months, up from 17% the year before. Satisfaction scores stay stable while the relationship thins, which is why measuring the rare moments matters more than the headline score.

Final thoughts

Banks lose trust at a fraud alert nobody answered, a document asked for twice, a bereavement handled by someone who did not notice the grief, and a complaint closed without an explanation. The app worked the whole time. The complaint maps from Brussels, The Hague, Paris and London say the same thing: fraud is where the relationship is tested now, and the handling is what customers remember. Measure the rare moments on their own, read what customers write, and act in the open. The trust will follow, and with it the money that was leaving without a word.
