Your Bank Has a Stranger Premium. Where Is Your Loyalty Premium?

Key Takeaways from This Blog:

• Banks should apply the same financial discipline used to attract new deposits to retaining and deepening relationships with their most valuable existing customers.
• Product-level pricing decisions can overlook the full value of a relationship, causing a bank to protect small amounts of revenue while risking much larger deposits and future business.
• Connected customer data, payment behavior, and explainable decision models can help banks deliver targeted pricing and rewards that influence the behaviors they want next.

Pull up your bank's latest deposit special and read the fine print. New money only.

The bank has already decided what it is willing to pay to attract deposits from someone it may barely know. Money already held by existing customers is excluded by design. Card bonuses and promotional loan rates follow the same logic. Now consider one of your existing customers: substantial deposits, a loan, active payments, and perhaps a business. How much should the bank be willing to give that customer through a better rate, a fee waiver or a reward to retain those deposits or win more of their business?

Most banks can't answer that question as quickly as they can price the deposit special. The deposit special is the stranger premium, and banks should keep it. What is missing is the loyalty premium: a calculated incentive for your best customers to stay and bring more of their financial life to your bank.

Product-by-Product Decisions Can Cost You the Relationship

Banks know what a deposit promotion costs. Lending knows what a rate cut does to interest income. Marketing knows what points and cash back cost. Each group can decide rationally for its product while the bank decides poorly for the relationship. Nobody owns the relationship, and nobody is paid on it.

Consider a customer with $800,000 in deposits and a $250,000 loan. A 20-basis-point reduction on that loan costs $500 of annual interest income if the balance remains at $250,000. At a one-percent annual contribution, those deposits are worth $8,000 a year. Holding firm protects $500. If the customer moves the relationship, the bank gives up $8,000 to save $500.

That does not mean the customer should automatically get the lower rate. The customer might stay without it. A fee waiver or rewards benefit might influence the decision at a lower cost.

Payments Show You Where the Customer Is Heading

Beyond what a relationship is worth today, the bank needs to know which way it is heading.

A customer may still have $500,000 at the bank while direct deposit has moved elsewhere, card activity is falling, and transfers to another financial institution are accelerating. The deposits are still there. The money movement says they may not stay.

Another customer may have modest balances but has just moved direct deposit in, increased card usage and begun making more payments through the bank.

Those signals raise the question that matters: what is changing in this customer's financial behavior, and should we respond now?

Pricing and Rewards Should Target the Behavior You Want Next

Banks already give customers financial value through preferential loan rates, higher deposit rates, waived fees, cash back and points. Those tools are usually managed separately, though they influence the same customer decisions.

Start with the behavior the bank wants. Retain $800,000 of deposits. Bring another $200,000 over. Move the operating account for a second business. Increase payment activity. Consolidate borrowing.

Then determine what that behavior is worth and what the bank will spend to influence it.

Only then decide what to offer.

For one customer, a 20-basis-point rate reduction on the next loan may help protect a much larger deposit relationship. Another may respond to a higher deposit rate. A third may care more about waived fees, cash back or rewards. Some customers may need no incentive at all.

If $300 in rewards produces the same result as $500 of forgone loan income, management should know it. If neither changes the customer's behavior, management should know that too.

The decision cannot end when the offer is made. Did the deposits remain? Did the customer bring another part of the business to the bank?

Over time, the bank learns which offers change valuable behavior and which give away revenue.

Pricing and Rewards Need Whole Customer Data

A relationship banker may already know that a customer owns a restaurant, recently started another company and is moving more money through the business. But that knowledge may not be available when a system is setting a loan rate, determining deposit pricing, assessing a fee or deciding which reward appears in mobile banking. And it certainly isn't available at scale and in real time.

Whole customer data has to be available when pricing and rewards decisions are made. That includes deposits, loans, payments, card activity, fees and other business the bank is permitted to connect. Assembling and interpreting all of that for every customer, every time something changes, has not been practical at scale. An intelligence layer with AI makes it practical, and it can draw on banker notes and service interactions, within the bank's controls.

The bank also needs to own the decision models and policies. Which behaviors qualify for preferential pricing? Which earn rewards? When should an offer be triggered? What happened after the customer received the offer? Which pricing differences can the bank explain to a fair-lending examiner? When designed effectively, the systems that make these decisions also provide answers to examiners by ensuring every decision is applied consistently, recorded, and explainable.

Those questions should shape every technology investment. If customer data, decision models and results remain trapped inside individual products or providers, the bank cannot make these decisions across the customer relationship.

None of this starts with technology. It starts with deciding what your best customers should experience. Without that vision, there is no strategy, just contracts that never add up to a deeper relationship.

Banks have spent years getting better at calculating what they will pay to attract new customers and deposits. The next competitive advantage will come from bringing the same rigor to the customers already inside the bank.

If your bank knows exactly what it will pay a stranger to bring money in, it should know exactly what it is willing to invest to keep its most valuable customers from taking money out. What is your loyalty premium strategy?
