SBS Bank Migrates Core Banking to Engine by Starling Cloud Platform

SBS Bank begins shift to cloud-native core banking platform

SBS Bank has launched a multi-year overhaul of its core banking infrastructure by adopting the Engine by Starling cloud-native platform. The transition involves a 10-year partnership agreement to replace legacy systems that currently manage all accounts, loans, and transaction records.

Why This Matters

Transitioning from on-premises legacy cores to cloud-native SaaS models addresses the technical debt inherent in tightly coupled, monolithic banking architectures. While ideal models suggest rapid digital transformation, the reality involves complex data migrations and multi-year implementation timelines to ensure security and operational continuity in highly regulated environments.

Key Insights

• SBS Bank signed a 10-year partnership with Starling in 2026 to modernize its core systems (Source: Reuters).
• Modular cloud-hosted platforms provide an alternative to high-risk in-house rebuilds or rigid legacy software (Example: SaaS Core Banking).
• Engine by Starling is a cloud-native tool currently utilized by Starling Bank, Salt Bank, and AMP.
• Implementation involves Deloitte New Zealand utilizing the Converge BankingSuite to streamline delivery and reduce internal software engineering requirements.

Practical Applications

• Use Case: SBS Bank implementing digital onboarding and smart money management tools; Pitfall: Legacy dependency bottlenecks delaying member-facing features until 2027.
• Use Case: Utilizing external system integrators like Deloitte to manage multi-regional delivery; Pitfall: Poor change management during the multi-year migration leading to internal operational disruption.
