Why low-code matters
Low-code platforms are increasingly influential in financial services. By enabling teams to build and adjust integrations without extensive manual coding, they help reduce onboarding delays, streamline workflow creation and lower the risk of errors.

Looking ahead
Corporate clients often face complex internal approval structures and limited IT resources. By absorbing the technical challenges associated with emerging standards, banks like Mizuho can improve client satisfaction, reduce onboarding bottlenecks and deliver a more predictable operational experience. This approach also strengthens customer loyalty in an environment where firms compare providers not just on fees but on the overall ease of doing business. said Nam.“ We’ ve built a scalable foundation that not only meets current compliance needs but also adapts to the next wave of Digital Transformation.”
The initiative has become a blueprint for how digital infrastructure can enable agility, innovation and better customer outcomes in a rapidly shifting regulatory environment. Mizuho is now looking to build upon this success, exploring further enhancements to its digital capabilities to serve a wider range of corporate client needs across the region.
“ Payments modernisation doesn’ t happen in a vacuum, it requires orchestrating old and new systems in a way that doesn’ t disrupt mission-critical services,” said David Irecki, Chief Technology Officer, Asia Pacific and Japan, Boomi.“ Mizuho Bank’ s approach blends compliance with client-centricity. By embedding ISO 20022 into a flexible integration strategy, they’ ve future-proofed their operations and unlocked new ways to innovate at scale.” p
