Banks operating across multiple regulatory jurisdictions often struggle to maintain consistency, accuracy, and traceability in their regulatory submissions. While MAS, HKMA, and the EBA’s CoRep framework follow the same global Basel principles, their interpretation, data definitions, templates, thresholds, and validation expectations differ significantly. These differences create operational inefficiencies, data gaps, mapping conflicts, and reconciliation issues. This paper outlines the practical challenges banks face across these three jurisdictions and highlights why harmonizing data models, validation rules, and governance frameworks has become critical for risk and finance teams.
