European insurers operate under a detailed risk-sensitive rulebook. Solvency II is the regulatory regime that sets capital requirements, governance standards, and disclosure rules for insurance and reinsurance undertakings in the European Union and associated states.

The framework rests on three pillars: quantitative capital requirements calculated from a standard formula or internal model, qualitative requirements for risk management and governance, and transparency through supervisory reporting and public disclosure. The solvency capital requirement is calibrated to a one-year value-at-risk measure.

Implementation demanded significant investment in data, models, and processes. Supervisors gained more sophisticated tools to compare companies and intervene early. Firms continue to refine internal models and ORSA processes under the regime. Solvency II has influenced capital standards discussions well beyond Europe.
