Fidelity National Information Services (FIS) announced that Japan‑based Mizuho Financial Group has chosen its Balance Sheet Manager platform to support the bank’s transition to the revised domestic accounting standards that align with International Financial Reporting Standard 9 and the expected credit loss (ECL) framework.

The new standards require banks to model and recognize credit losses using a forward‑looking ECL approach, a process that is data‑intensive and computationally complex. FIS’s Balance Sheet Manager offers deep and extensive modelling, scenario and simulation capabilities for asset‑liability management, enabling Mizuho to streamline regulatory reporting and maintain compliance as the regulatory environment evolves.

Mizuho’s Deputy General Manager in Credit Risk Management, Yutaro Aiuchi, said, “As we prepare for these significant accounting standard changes, we needed a solution that combines robust compliance capabilities with operational flexibility. FIS Balance Sheet Manager stood out for its ability to handle complex accounting needs with precision. New efficiencies through data integration and reporting will also help us optimize our risk profile and enhance our competitiveness. This implementation represents an important step in our ongoing commitment to regulatory reporting excellence.”

The win adds a high‑profile client to FIS’s portfolio and strengthens its foothold in the Japanese market, where regulatory compliance is a growing focus for large financial institutions. FIS, a global leader serving over 400 institutions, recently issued senior notes totaling more than $7 billion to refinance debt, underscoring its active financial management and strategic positioning.

FIS President, Capital Markets, Andrés Choussy noted, “Financial institutions in Japan and across the globe face complex challenges especially during times of financial volatility. FIS' technology takes away the burden of regulatory reporting from our clients and enables them to concentrate on their business goals. Our solutions help forward‑looking institutions like Mizuho confidently put money to work while maintaining the compliance and clarity needed to grow.”
