By 2030, Millennials and Gen Z will control $41 trillion in inherited and earned wealth. By 2035, Gen Z will represent 43% of retail banking revenue, up from just 32% in 2023. The customers who will define your bank's future are arriving now. The only question is: Will they choose you?

The loyalty you assume you have

As our 2026 Consumer Banking Report demonstrates, older generations are likely to stay put. Younger ones won't. Our research shows that 34% of Gen Z and Millennials would consider switching banks in the next 12 months, more than triple the rate of Boomers. More concerning, 53% of these younger consumers now view the idea of "one main bank" as a thing of the past.

Driving that restlessness is a sense that their bank is more like a utility that doesn’t add value. Only 27% of consumers view their bank as a “valued partner,” and 47% see it as nothing more than a “useful resource.” That gap is the heart of the problem. 

Your customers are ready for AI

The encouraging news: Younger customers aren't fleeing banking. They're searching for something better. 

That appetite is real and measurable. Some 61% of Gen Z and 52% of Millennials noted they would pay for premium services, including features like personalised financial guidance, representing a large, untapped source of revenue for banks which AI could quickly unlock. Case in point, 53% of Gen Z would pay for hybrid AI-and-human advisory models. Meanwhile, 45% feel their bank isn't doing enough to improve their financial literacy, and 58% would welcome AI to help close that gap.

It would be a major failure to not deliver it while the crucial window to win them over remains open.

AI augmentation, not replacement

Here's the nuance many executives miss. Globally, comfort with bank-provided AI has reached a tipping point. But comfort with AI hasn’t replaced trust in human expertise: 86% of consumers are comfortable acting on advice from a human advisor, versus 50% for AI alone. 

The winning model isn't automation that removes the human. It's intelligence that makes banks more proactive, that leaves customers more informed and that helps the bank to be more present at the moments that matter most to customers.

The window is narrower than it looks

The report is blunt about timing. Consumer comfort with AI “has crossed the threshold for mainstream adoption,” creating a narrow window for banks to build AI differentiation that can deliver on the expectations of Gen Z and Millennial customers. It adds: “The leaders who move in 2026 will define customer expectations; followers will struggle to catch up.”

This isn't a soft deadline. Banks beginning transformation in 2027 or 2028 will struggle to compress the learning curve and catch leaders, who will have a sufficient head start offering profound value to a vital cohort of customers at the time they demand it most.

In other words, we’ve passed the threshold of consumer readiness. Now it’s about institutional delivery.

The choice is in front of you

The wealth transfer is happening. Concurrently, the demand signal is unmistakable and the technology is proven. 

The report frames the stakes as a single question: Will your institution be the one that defines the next era of banking, or the one that scrambles to match competitors who do? The answer is still yours to write, but the window to do so is closing.
