Episode 257: How do you earn the next banking customer's loyalty, one moment at a time? Focus on what customers choose, and why.

According to John Finley, head of marketing, technology, and innovation at BMO, a bank operating across North America, customer loyalty shifts with context. His team takes signals—what customers say—and wires them back into the very next touch. They then test whether the micro-fix actually changes the next behavior. The goal is to earn the next choice—and the corresponding interaction.

To make this happen, BMO runs targeted interventions wherever friction points show up. For example, "Customers who don't know who their banker is are much more likely to be a detractor," explains John. To address this, BMO will reintroduce the customer to their banker and then track whether that specific change moves the next response.

It's a practical and simple playbook: close rapport gaps, personalize the next contact, and measure whether advocacy—not just willingness to recommend alone—drives ongoing loyalty.
