Mizuho Banking - Finance and Accounting Summer Internship

Mizuho is not your typical financial institution.

We offer a fantastic opportunity to gain experience within a global investment bank, working on real projects, whilst developing a strong professional network within a bank that prides itself on its inclusive, cooperative and friendly company culture.

We offer the best of both worlds - the feeling of a boutique work environment within a global organisation. Our steady growth in EMEA gives our people at all levels rewarding degrees of responsibility and a richer work experience than a small firm or an established giant could offer alone.

Summer Internship – Finance Department 

The Mizuho Finance team provides support to both Mizuho International plc (MHI) and Mizuho Bank, Ltd., London Branch (MHBK), encompassing a wide spectrum of internal clients including the MHI Board and its sub-committees, MHSC (as the shareholder of MHI), Senior Management, Head Office and the business lines. It fulfils the role and responsibility of providing internal and external financial measurement and reporting on business performance to management and all areas of the global organisation.

What will I be doing?

Over the course of your 10-week internship, you will gain hands-on experience across the Finance Department, rotating through its specialist teams and supporting on live projects. Typical responsibilities may include:

• Financial Control – assisting with published accounts, management reporting, and business planning activities.
• Product Control / Product Accounting – supporting financial reporting and control functions, including balance sheet valuation, and working closely with Risk Management.
• Regulatory Reporting – contributing to the calculation, monitoring, and reporting of regulatory capital and liquidity to senior management and regulators.
• Tax – helping with tax policy and compliance processes, including interactions with tax authorities.
• Procurement & Accounts Payable – assisting with contract negotiations, supplier management, and processing non-trading cashflows.

This internship will give you broad experience across the Finance function, helping you understand how financial information underpins decision-making in a global investment bank.
