Generative artificial intelligence (GenAI) and agentic models are revolutionizing financial services, transforming user experience, fraud detection, payments innovation and compliance processes, according to John Kain , head of financial services market development at Amazon Web Services (AWS).
“AI has been such an integral part of how the industry has modernized over the last decade. It really is in every part of the financial services value chain,” the former JPMorgan executive said in an interview with PYMNTS. “What’s dramatically changed in the last two years is the impact of generative AI on all those processes.”
Kain sees three overarching trends across banking, capital markets, insurance and payments: End-to-end user experience: AI enables seamless onboarding, product recommendations, servicing and back-end processing. It is also powering hyper-personalized experiences, enabling firms to tailor offers, advice and communications in real-time based on user data and behavior.
Data modernization: Legacy systems are being upgraded to unlock core data, enabling more personalized services and better analytics.
Embedded financial services: Firms are embedding financial tools into broader value chains, meeting users at any channel, whether in eCommerce, social platforms or mobile apps.
In the payments space, Kain highlighted the global rise of real-time payment systems, from India’s UPI (Unified Payments Interface) to Brazil’s Pix, which offer instant settlements and low fees. In the U.S., banks are now leading the charge, according to a PYMNTS Intelligence report in December.
“These changes are transforming customer expectations,” Kain said, adding that innovations like buy now, pay later and stablecoin rails are creating new challenges for infrastructure and fraud prevention.
Machine learning is being deployed to improve fraud detection — especially for instant payments, where there’s little room for error. AWS is also seeing adoption of techniques like distributed model training for fraud and clean room environments to share fraud data across institutions.
