Why Rewarding the Whole Banking Relationship is the Future of Loyalty

Customer loyalty in the banking sector looks much stronger on paper than it is in reality. Accenture’s 2025 Global Banking Consumer Study reveals the harsh reality: 73% of customers engage with multiple banks beyond their main bank.

In addition, nearly 1 in 3 consumers will stop doing business with a brand they love after just one bad experience (PwC), and 75% have switched brands or behaviors recently (McKinsey). In banking, the reality of customer churn isn’t a simple “stay or leave” state. It’s more like a sliding scale of customer satisfaction that becomes eroded over time by undifferentiated rewards.

Today, banks spend heavily on rewards programs, yet most run them in isolation with credit card points,deposit bonuses and mortgage perks all in completely different silos. As a result, high-value, multi-product customers don’t always receive the differentiated recognition and service experience that reflects their deeper relationship with the bank.

When loyalty programs operate as one-size-fits-all instruments, the most valuable customers will inevitably feel undervalued.

The root cause: “tidally locked” rewards programs

Why are we stuck in this paradigm? Rewards programs are usually hardwired to individual product lines rather than built as enterprise-wide engagement platforms. And this stretches from the bank’s backend technological infrastructure all the way through to marketing approaches.

Because of siloing along product lines, and because many banks have grown through acquisitions, a single institution may be juggling dozens of completely separate systems, customer databases, and marketing teams. This fragmentation means that their reward programs become locked to specific product lines, instead of encompassing the customer’s _overall _relationship with the bank.

Flipping the loyalty model

To build a loyalty ecosystem that sees across a customer’s full suite of products, banks must flip the traditional model on its head. Instead of starting with a financial product and trying to build a customer base around it, institutions need to start with the individual customer and build the value up from there.

American Express is a good example of this approach. It operates in an insular environment where the customer is placed firmly at the center of the value proposition. The American Express Membership Rewards program allows cardholders to earn points on everyday purchases and redeem  points that never expire for statement credits, travel, gift cards, etc. To follow AmEx’s lead, banks should have (or must build) the capability to segment their customers into tiers and recognize their total contribution differently.

Building a digital memory

Unifying rewards across multiple, disparate product lines does create operational and technical challenges that will take time to resolve. For example, integrating disparate systems of record across debit and credit portfolios often forces vendors to perform totally separate integrations before rolling them up into a single platform.

However, institutions do not necessarily need to embark on gigantic systems overhauls to achieve this. According to Mike Abbott, global banking and capital markets lead at Accenture, “Banks need to create a ‘digital memory’ of the customer that consolidates data from every interaction and every product into a unified, real-time profile.”  He added, “Customers want what they had 30 years ago with the branch manager — where they listened and remembered you and who you were — done digitally.”

By implementing a data layer that collects and consolidates behavior signals across all of a bank’s products and programs, loyalty teams gain a single place to access overall bank relationship data, and from there can build ways to offer ongoing recognition.

The shift to platform-wide engagement

The great news is that we are already witnessing a shift in how banks approach loyalty and product marketing. Historically, bank websites and mobile apps have been designed for servicing (e.g. check account balance, pay bills, transfer money), but now they are rapidly transforming into active marketing channels.

This new approach to engagement redefines a bank’s role, turning it into a trusted financial copilot that offers valuable advice to help customers make smart money decisions when they shop, choose insurance, or improve their credit scores.

To take this engagement further, banks must further elevate their perspective from isolated product interactions to a platform-wide view of the whole customer relationship. This pivot requires tapping into rich behavioral signals - especially how and where customers shop. When a financial institution understands a customer’s daily purchasing habits, it can deliver hyper-personalized guidance that actually helps users make smarter money decisions in real-time.

Institutions can achieve this by leveraging a unified data layer that captures these continuous shopping behaviors across all of the bank’s programs. The constant flow of actionable data enriches the bank’s understanding of the customer, enabling the bank to deliver tailored rewards, relevant bank product cross-sells, and highly personalized experiences seamlessly. It creates a rewarding loop where behavioral clues can inform better banking experiences, which in turn deepen the customer’s overall relationship with the institution.

The ROI of company-wide rewards

When a bank rewards the total relationship instead of isolated activity on a single product, the behavioral shift is profound. Accenture found that customers who feel valued hold 17% more products and give 5% to 30% more share of wallet to their primary bank. Furthermore, Capgemini’s World Retail Banking Report 2025 showed that 52% of customers say they would buy more financial products if incentives were tied to overall engagement rather than a single product.

For an industry where loyalty seems to be fragmenting more and more, and where consumers have near-unlimited choices between financial services providers, these are game-changing numbers.

When recognition becomes continuous rather than a one-off or occasional reward, the banking relationship itself becomes the switching cost. To me this indicates that rewarding the whole customer relationship is the ultimate growth engine.
