Mizuho Bank taps Boomi for ISO compliance

AI automation platform Boomi has been tapped by Japan’s Mizuho Bank to modernize and consolidate its payments infrastructure across Asia-Pacific, enabling the bank to meet ISO 20022 requirements while simplifying client onboarding and reducing operational complexity.

In an announcement on Thursday, 13 November 2025, Boomi said the bank has deployed the Boomi Enterprise Platform to harmonize file conversion tools, streamline payment instruction processing, and shield clients from the technical challenges of the ongoing SWIFT MT-to-ISO 20022 transition.

Mizuho Bank, part of one of the world’s largest financial groups, saw the migration as an opportunity to upgrade customer experience rather than impose new processes on clients.

“We knew the ISO 20022 transition had the potential to disrupt our clients’ day-to-day operations. Instead of pushing that complexity onto them, we decided to own it,” said Andy Nam, Regional CIO at Mizuho Bank. “This project allows our clients to continue using their familiar file formats while we handle the conversion invisibly in the background. That kind of simplicity requires serious backend sophistication.”

Under the initiative, Mizuho replaced disparate file-conversion tools across its APAC operations with a single digital interface powered by Boomi. Clients can now upload or enter payment instructions using either legacy formats or ISO 20022. The platform converts, validates, and transmits instructions securely through a low-code, web-based portal, cutting onboarding times from months to weeks and reducing cost-to-serve.

“Getting the project live in a rapid timeframe was a big win, but the real achievement is what it has enabled,” Nam added. “We’ve built a scalable foundation that not only meets current compliance needs but also adapts to the next wave of digital banking transformation.”

Boomi noted that Mizuho’s approach provides a model for financial institutions modernizing payments infrastructure without disrupting mission-critical services.

“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, at 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.”
