What each one covers
Between them, COREP and FINREP give a supervisor a standard view of every bank’s safety and financial position.
How the reporting works
The EBA defines the templates and the data behind them, and publishes them in numbered reporting framework releases. Each release comes with a data point model and an XBRL taxonomy generated from it (EBA). Banks submit to their national supervisor, mostly quarterly, with liquidity reported more often. National supervisors validate the returns and pass data on to the EBA.
The pace of change is the hard part. Framework 4.0 applied from March 2025 to bring in the CRR3 changes, and 4.4 is already phasing in from December 2026.
What supervisors elsewhere can borrow
Many authorities outside Europe base their prudential returns on the same Basel standards, and some model their templates on COREP and FINREP directly. You do not need to copy the full framework to benefit. The ideas that travel are the ones underneath it: define each figure once, describe it by its dimensions, publish validation rules alongside the templates, and version every change.
Where AI fits, and where people decide
With hundreds of templates per bank, the risk is that supervisors only ever look at the headline ratios. AI can read the full set as it lands, compare it with prior periods and peers, and draft questions on the movements that matter, citing the cells behind each one. Validation rules decide whether a return is accepted. Supervisors decide what a movement means.
- 1Map your current prudential returns against the COREP and FINREP blocks to find gaps and duplicates.
- 2Define each figure once, with a single owner, before you design any template.
- 3Publish validation rules with the templates, not after the first filing cycle.
- 4Version every change and keep a mapping between versions so trends do not break.
- 5Decide upfront which movements supervisors will review each quarter, and automate the rest of the reading.
Where Line4 fits
Line4 is a SupTech platform for financial regulators. It collects returns in XBRL, Excel and CSV, validates them against your taxonomies and rules at the point of submission, and puts AI to work reading them, with supervisors making every decision. If you work with a standard we have not yet run in production, we will say so plainly and show you how we would approach it.
Questions
What is COREP?
COREP (common reporting) is the EU framework for banks to report capital adequacy and related prudential data, including own funds, capital requirements, large exposures, leverage and liquidity, to their supervisors.
What is FINREP?
FINREP (financial reporting) is the EU framework for banks to report financial information, including the balance sheet, profit and loss, and asset quality such as non-performing and forborne exposures.
Who defines COREP and FINREP?
The European Banking Authority defines the templates, data point model and XBRL taxonomy, and publishes them in numbered reporting framework releases.
What format are COREP and FINREP submitted in?
XBRL, using the EBA taxonomy generated from its data point model, submitted to the national competent authority.
Do COREP and FINREP apply outside the EU?
They are EU frameworks, but supervisors elsewhere often use similar Basel-based returns and can borrow the same design principles.
