The three pillars
Solvency II is built on three pillars, and reporting runs through all of them.
How QRTs reach the supervisor
Firms submit quarterly and annual QRTs in XBRL against the EIOPA taxonomy, which is generated from EIOPA’s data point model. The national supervisor validates them and passes data on to EIOPA. Narrative reports, the public SFCR and the private regular supervisory report, travel alongside, usually as documents.
The 2027 review
Directive (EU) 2025/2 amends Solvency II and applies from 30 January 2027 (EUR-Lex). It brings changes to calculations, proportionality and reporting and disclosure, and arrives with a new framework for insurance recovery and resolution. For supervisors, it means new taxonomy versions, new validation rules and a cycle of questions from firms.
What supervisors do with the data
Monitor solvency ratios and their trends, compare firms with peers, spot early warning signs in investments, reserving and reinsurance, and then read the narrative reports to understand why. The numbers say what the position is. The narrative explains it. In most authorities, connecting the two is still manual.
Where AI fits, and where people decide
AI can read the SFCR and the regular supervisory report against the QRT figures and flag where the story and the numbers disagree, with a citation to each. Deterministic rules calculate ratios and run the checks. The supervisor decides what is a concern and what to ask the firm.
- 1Map which templates and narrative sections change for your market.
- 2Test the new taxonomy against last year’s real filings before firms do.
- 3Brief firms early on new validation rules and which ones will block a submission.
- 4Review which checks should block and which should only warn.
- 5Use the change to link narrative reports to the figures they explain.
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 are Solvency II QRTs?
Quantitative Reporting Templates are the standard quarterly and annual templates insurers and reinsurers use to report solvency and financial data to their supervisor under Solvency II. They are submitted in XBRL against the EIOPA taxonomy.
What is the difference between the SFCR and the RSR?
The Solvency and Financial Condition Report is published. The regular supervisory report goes only to the supervisor and contains more detail.
When do the Solvency II review changes apply?
Directive (EU) 2025/2, which amends Solvency II, applies from 30 January 2027.
What is the latest EIOPA Solvency II taxonomy?
EIOPA released version 2.10.0 of its Solvency II taxonomy in July 2026. Check EIOPA’s site for the current version before planning a release.
How can AI help insurance supervisors?
AI can read narrative reports against reported figures, flag inconsistencies with citations, and draft questions for firms. Rules calculate ratios and supervisors make the judgements.
