Why banks still rely on legacy cores for pricing and how to break free

December 18, 2025

Banks have modernized payments, billing, and customer data but interest and fee pricing parameters remain trapped inside legacy core banking systems. In this video, Zafin’s Principal Architect Arno Hensbergen unpacks the historical reasons behind core dependency. From the rise of call centers to the explosion of digital channels, he explains how scattered customer and account data can lead to technical debt, compliance risks, and operational bottlenecks for banks.

You’ll learn:

  • Why interest and fee pricing are still tied to legacy mainframes
  • How data fragmentation across channels became a major compliance issue
  • The impact of rising regulatory pressure (AML, KYC, customer due diligence)
  • How core modernization carved out payments and billing but left interest behind
  • Why delivering real-time, hyper-personalized pricing is now essential
