22 April 2026 – Tokyo – Numerical Technologies (“NumTech”)’s session was included in a feature published in the 22 April edition of Nikkei covering FIN/SUM 2026.
The feature covers a dialogue on the application of AI in Net Interest Income (NII) management in banking, featuring Hideyuki Torii (President & CEO, Numerical Technologies), Siaw Kian Zhong (COO/CTO, Numerical Technologies), and Haruhiko Yoshida, Deputy Head of Corporate Risk Management Division at MUFG Bank.
During the dialogue, from a banking practitioner’s perspective, Mr. Yoshida highlighted key challenges such as ensuring consistency in interest rate scenarios, analysing asset and liability structures, and detecting anomalies, as well as expectations for the application of AI to address these issues.
NumTech introduced concrete approaches to these challenges, including the automation of market scenario generation (accelerating hypothesis generation), reverse-engineering support for future balance sheet design, and the enhancement of difference analysis and data anomaly detection.
It also explained that, in practical applications, AI should not replace human judgment but should be implemented within workflows designed to support human decision-making. Furthermore, the importance of a “glass box” design to ensure transparency and auditability, as well as the need for robust system security and AI governance, was emphasized.
