Why regulatory reporting becomes fragile
Most banks did not design their regulatory reporting; it accumulated. Each new requirement, from Basel III capital adequacy and leverage ratios to the Liquidity Coverage Ratio (LCR), Net Stable Funding Ratio (NSFR) and IFRS 9 expected credit loss disclosures, was met with another spreadsheet, another manual adjustment or another tactical extract from core banking. Over time, finance, risk and treasury teams end up reconciling the same balances in different ways, and every reporting cycle depends on a few individuals who understand how the numbers really fit together.
Start with the data, not the template
Sustainable reporting transformation begins upstream. Banks need a consistent, reporting-ready data layer that brings together core banking, general ledger, treasury and risk systems, with clear ownership, documented lineage and automated data quality checks. When source data is transformed and aggregated once, in a governed way, the same foundation can serve capital, liquidity, financial and management reporting. This is also the heart of BCBS 239: accurate, complete and timely risk data aggregation that a bank can evidence to its supervisor.
Build calculation engines and controls that teams can own
Regulatory calculations such as risk-weighted assets, high-quality liquid assets or stable funding factors should live in transparent, rule-based engines rather than hidden spreadsheet formulas. Reconciliation, validation and sign-off controls should be built into the flow, so issues surface before submission rather than after. Just as important, the solution must be something internal teams can maintain and extend when regulations change, without relying on external consultants for every update.
Deliver in structured, controlled stages
Large reporting programmes fail when they try to change everything at once. A practical approach is to understand the regulatory, data and technology landscape first, structure the target architecture and implementation plan, and then deliver iteratively, return by return, with parallel runs and clear governance. This keeps regulatory deadlines safe while steadily replacing manual effort with automation.
