Automating regulatory reporting for a regional bank
A governed data warehouse and lineage framework replaced a spreadsheet-driven reporting process prone to manual error.
Client challenge
What was wrong with the legacy environment
Regulatory figures were assembled manually across spreadsheets each cycle
No consistent lineage from source transaction to reported figure
Reconciliation between source systems and reports was fully manual
Reporting cycles consumed nearly a full working week each quarter
Modernization approach
How Karsient approached the transformation
Karsient designed a governed reporting warehouse with full source-to-report lineage, replacing manual spreadsheet assembly with automated, auditable pipelines aligned to the bank's regulatory calendar.
Architecture
The modern target architecture
Governed ingestion from core banking and general ledger systems
A lineage-tracked transformation layer mapping every reported figure to its source
Automated reconciliation checks between source systems and reporting outputs
Role-based access aligned to regulatory and audit requirements
Migration
Migration & re-engineering strategy
Reports were migrated one regulatory submission at a time, each run in parallel against the legacy spreadsheet process for a full cycle before the manual process was retired.
Engineering improvements
What changed under the hood
End-to-end lineage from source transaction to reported figure
