Retail Banking Customers, Needs and Channels

Why do retail banks segment customers?

Retail banks serve customers with very different financial circumstances, behaviours and preferences. Customer segmentation groups people with similar characteristics or needs so that providers can design more relevant products, services and ways of serving them.

Segments might include students, homeowners, mass-affluent customers, retirees or self-employed customers, but these groups can overlap. Segmentation should therefore provide a starting point rather than define an individual. Effective retail banking combines an understanding of broader customer groups with recognition of each customer’s particular circumstances.

How do customers’ financial needs change?

Financial needs often evolve alongside changes in customers’ lives. Someone starting out may need a first account, budgeting tools or savings for a first home. Later priorities may include mortgages, insurance, family finances and longer-term saving.

Customers may then focus more on building financial security through savings, investments and retirement planning, while later-life needs can include retirement income, fraud protection and accessibility support. These journeys are not fixed or identical, so banks need to respond to customers’ actual circumstances rather than assume everyone follows the same path.

How do customers choose how to bank?

Customers can access retail banking through mobile apps, online banking, branches, banking hubs, contact centres, messaging, video advice, ATMs and third-party platforms.

The most appropriate channel depends on the task, its urgency and the customer’s preferences. A mobile app may suit an everyday payment, while mortgage advice may require a conversation with an adviser. An omnichannel approach connects these channels, allowing customers to move between them without restarting a process or repeatedly providing the same information.

What makes a good customer experience?

Retail banks increasingly use customer data, sometimes supported by AI, to provide fraud alerts, spending insights, savings prompts and more relevant support. Used responsibly, personalisation can improve outcomes; used poorly, it can undermine trust or result in inappropriate treatment.

Customer experience also depends on reducing unnecessary friction, such as repeated information requests, confusing terms, long waits or inconsistent service. Banks must balance convenience with security and fairness, while ensuring customers who may be more susceptible to harm can access clear communication, appropriate support and suitable channels.
