Modernization in banking: from AI pilots to AI-native operations

Banking is entering its third wave of transformation. Internet banking digitized the branch, mobile digitized the wallet, and AI-native banking is now digitizing the operating model itself. Yet while 92% of global banks run AI in at least one core function, only 1 in 4 use it for competitive advantage. The rest are stuck in fragmented pilots as digital challengers iterate in real time.

This report shows why most modernization programs stall and how leading banks close the gap through progressive modernization: one domain at a time, end to end, with existing cores kept in place and value delivered every quarter.

What's inside?

• The 2027 outlook: Five forces reshaping how banks compete, from AI productivity and deepfake fraud to invisible payments, open finance, and the race against digital challengers.
• Why modernization stalls: The three patterns behind stalled programs (fragmentation, sequencing, and governance debt), and why rip-and-replace can't keep pace with the market.
• The progressive modernization playbook: A four-step, value-led approach to modernizing domain by domain, with pilots that prove the model in a quarter, not a year.
• Where to start: Five journeys delivering the fastest, most measurable returns today: onboarding, origination, fraud prevention, RM productivity, and conversational banking.
