Pam Quinn-Boland asks what might happen when a bank better understands a customer’s life, not simply their products.

Sarah’s fixed-rate mortgage is coming to an end. Her bank knows the date. It knows her monthly payment and the balance of any savings she holds there. It can send her a reminder and a link to its latest fixed-rate deals.

What it can’t necessarily see is that she has started helping her parents with their bills, or that one of her children will soon need support through university. Sarah could tell the bank. But first she has to work out which details matter, what her options are and whom to speak to. Her finances are spread across several products; her life, rather inconveniently, is not.

A good bank manager might once have asked Sarah what else had changed. A private banking adviser might ask a wealthier customer that question today. Sarah’s app knows when her mortgage rate expires; it doesn’t know why the answer matters.

What would banking look like if more people got that kind of attention?

Remember the person, not just the transaction

The answer isn’t another chatbot that knows Sarah’s name or remembers her last query. It’s a service that can carry relevant context from one interaction to the next, recognise when a decision is approaching and help her understand the choices in front of her.

This is one of the promises of delegated banking. With the customer’s permission, a bank could do more of the preparation: gather information, spot a possible issue, explain the trade-offs and connect the right people and services. As a result, the customer needn’t arrive knowing which product, department or form to ask for.

Private banking offers a glimpse of what that could look like. At its best, an adviser knows a client’s goals and family circumstances, gets in touch before a big decision and brings in other specialists when needed. The client doesn’t have to explain their life from scratch each time.

Intelligent services could make some of that continuity possible for many more people. For someone whose pay varies each month, it might mean spotting an approaching shortfall, explaining their options before a payment is missed and offering a route to a specialist. That sort of attention shouldn’t depend on having an investment portfolio.

Start with what has changed

Imagine Sarah’s mortgage renewal a year from now. Rather than sending a generic prompt to choose a new rate, her bank gets in touch early and asks if she would like help planning for what comes next.

With her permission, it brings together her mortgage details, relevant spending and savings information, including information from other providers she chooses to share. Then it asks a question that a database cannot answer: “Is your situation the same as it was when you last reviewed this?”

Sarah mentions the support she’s giving her parents and the possibility of university costs next year. Now the question is bigger than which mortgage rate looks cheapest. How much room will she need in her monthly budget? What savings buffer would help her feel secure? Would a lower payment now mean paying considerably more over time?

The bank could show how different mortgage options affect those wider choices, including the assumptions behind each scenario. It could gather the information Sarah chooses to share, arrange a conversation with a specialist who understands what she’s weighing up, and help her prepare for it. 

Once she decides what to do, it could organise the agreed paperwork and set a check-in when her caring costs become clearer. Sarah makes the important choices; the bank takes on more of the work around them.

That would feel very different from being shown a product the bank thinks she is likely to buy. Personalisation can make a sales message more relevant. Useful support helps someone understand a decision.

That doesn’t mean that “knowing the customer” should mean building an invisible profile of everything the bank can infer. Instead, think of it as a customer-controlled financial passport: a small, reviewable record of goals, preferences and boundaries that Sarah chooses to share. 

She might want the bank to remember that she prefers plain-English explanations and wants to preserve an emergency fund. She should be able to see what is stored, change it or withdraw permission for its use at any point.

Context can go stale too. Before a major decision, the bank should check what’s changed rather than assuming that yesterday’s priorities still apply.

How helpful is too helpful?

There’s a difficult line here. Explaining how several mortgage options could affect Sarah is one thing. Steering her towards a particular product on the basis of her circumstances raises different questions about advice, suitability and accountability.

Banks cannot solve that by calling every interaction “guidance”. The substance of what the service does matters. In the UK, the FCA’s Advice Guidance Boundary Review recognises the need for more useful forms of financial support. Its targeted-support regime concerns pensions and retail investments; it’s not a general permission slip for an AI assistant simply to recommend any financial products.

Any service must make clear whether it’s explaining possibilities, providing a form of regulated support or giving advice. It should show the basis for what it says, acknowledge uncertainty and bring in properly qualified people when the decision calls for them. And it must be prepared for the most useful answer to be “stay where you are” or “another provider may suit you better”. Otherwise, “helpful” could quietly become “most profitable for the bank”.

A better handover to a human

What made a good bank manager useful was the ability to remember what mattered to a customer, ask the next sensible question and know when to bring in an expert. Digital banking has given customers speed and convenience. It hasn’t always carried that understanding from one conversation to the next.

Technology could help restore some of that continuity. If Sarah speaks to a specialist, that person should know what she’s already explored and where she remains unsure. They should also be able to question the technology’s conclusions, not simply read from them.

Some customers will want that conversation earlier. Others may prefer to explore privately first. Good support makes room for both, and gives people a clear way to reach a human when they need one.

What the future has in store

Banks have already seen customers place significant trust in relationship managers, branch managers and private banking advisers. These individuals often understood goals, family circumstances, future plans and financial concerns that sat well beyond individual products. 

The challenge is not whether customers will ever share context. History suggests they will. The challenge is whether banks can create enough value, transparency and control that customers choose to share that context again – in a digital world.

Banks don’t need to know everything about a customer’s life to be more useful. They just need to fully understand what they do know, ask about what they don’t – and make fewer assumptions in between. The measure of success may be less about how often someone opens the banking app, and more about whether the bank makes a difficult decision easier.

The future may not give everyone a private banking service, but it could give far more people something they have rarely had from their bank: relevant help before a problem becomes urgent, a clear account of their choices and a conversation that starts where the last one ended.
