FIS and Japanese banking giant Mizuho Financial Group have entered a partnership aimed at helping the institution adapt to evolving regulatory reporting requirements in Japan.
The collaboration will see Mizuho deploy FIS’ Balance Sheet Manager solution as the bank prepares for upcoming changes to domestic accounting standards that will align more closely with international frameworks.
The partnership was established to support Mizuho as it navigates revisions to Japan’s accounting rules, which are expected to align with the International Financial Reporting Standard 9 (IFRS 9). With regulators introducing new expectations around how banks measure and recognise credit losses, Mizuho required a technology platform capable of ensuring compliance while maintaining operational flexibility as its business continues to grow.
FIS is a global FinTech company that provides technology solutions to financial institutions, merchants and capital markets firms worldwide. Its platforms cover areas such as payments, banking technology and capital markets infrastructure, enabling financial institutions to manage risk, improve efficiency and support regulatory compliance. The company’s Balance Sheet Manager solution is designed to help banks strengthen their asset liability management (ALM) capabilities through advanced modelling, scenario analysis and simulation tools.
Mizuho Financial Group is one of Japan’s largest financial institutions, offering a wide range of banking, asset management and financial services to corporate and retail clients across the globe. Through its credit risk management and financial reporting operations, the firm is responsible for meeting strict regulatory requirements and ensuring that its balance sheet and loan portfolio are managed in accordance with evolving global standards.
Under the agreement, Mizuho will use FIS Balance Sheet Manager to support its compliance with the revised domestic accounting standards in Japan. The platform will enable the bank to implement robust modelling capabilities and scenario simulations to support ALM processes while helping it adapt to the “expected credit loss” (ECL) framework introduced under IFRS 9.
The new accounting standards require banks to conduct forward-looking assessments of credit losses across their loan portfolios rather than relying solely on historical data. This shift requires financial institutions to process large datasets and run complex scenario modelling exercises, tasks that can become resource intensive and prone to errors without automated solutions. FIS’ technology aims to streamline these processes by automating calculations and integrating data across accounting workflows, allowing institutions to better understand their risk exposure and capital allocation.
The solution also offers automation that allows institutions to manage multiple accounting processes after ECL calculations without requiring additional system customisation. This capability is intended to help banks manage regulatory reporting more efficiently while maintaining accuracy across complex financial datasets.
Mizuho Financial Group deputy general manager in credit risk management department 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.”
FIS president of capital markets Andrés Choussy said, “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.”
