Case Study: Mitsubishi UFJ (MUFG) reduces spreadsheet risk and improves compliance with Mitratech

How Mitsubishi UFJ Securities International reduced spreadsheet risk and improved compliance

Mitsubishi UFJ Securities International (MUSI), the European hub of Mitsubishi UFJ’s securities and investment banking arm, relied heavily on spreadsheets across critical business processes. Rapid expansion and strict regulatory requirements (FSA, SOX) exposed operational and compliance risk: network scans found thousands of spreadsheets and MUSI needed a demonstrable control framework to manage risk while supporting complex product trading.

MUSI implemented ClusterSeven after a short consultation and a five‑week rollout, gaining cell‑level change logging, integrity rules and a “movie” view of spreadsheet evolution. The system improved product control, enabled auditability, strengthened SOX/FSA compliance (with positive regulator feedback), reduced errors and delays, boosted productivity and lowered long‑term costs, and is now being considered for wider deployment.
