📋 '''Use test''' is a qualitative requirement under [[Definition:Solvency II | Solvency II]] that obliges [[Definition:Insurance carrier | insurers]] using an [[Definition:Internal model | internal model]] for regulatory capital purposes to demonstrate that the model is genuinely embedded in their risk management and decision-making processes — not merely built to satisfy supervisory expectations. The concept addresses a fundamental concern regulators have with model-based capital frameworks: that a firm might construct a sophisticated model to achieve a favorable [[Definition:Solvency capital requirement (SCR) | solvency capital requirement]] while actually running the business on entirely different tools and assumptions. Under Article 120 of the Solvency II Directive, the use test requires that the internal model play a meaningful role in [[Definition:Risk governance | risk governance]], [[Definition:Capital management | capital management]], strategic planning, and [[Definition:Asset-liability management (ALM) | asset-liability management]], ensuring alignment between the model used for regulation and the model used to steer the enterprise.

🔍 Satisfying the use test in practice demands that an insurer weave its internal model outputs into a broad range of operational and strategic activities. Board and senior management must be able to show they understand the model's outputs and use them when setting [[Definition:Risk appetite | risk appetite]] frameworks, approving [[Definition:Underwriting | underwriting]] strategies, designing [[Definition:Reinsurance | reinsurance]] programs, and allocating capital across business lines. The [[Definition:Own risk and solvency assessment (ORSA) | ORSA]] process, for instance, should draw directly from the internal model rather than relying on a parallel set of calculations. Supervisory authorities — including [[Definition:European Insurance and Occupational Pensions Authority (EIOPA) | EIOPA]] and national competent authorities — assess compliance through documentation reviews, management interviews, and governance audits. They look for evidence such as board minutes referencing model results, investment committee reports driven by model analytics, and product pricing that incorporates the model's view of [[Definition:Risk margin | risk]]. If the model sits unused in a back office while executives rely on spreadsheets or legacy tools, the use test fails regardless of the model's technical sophistication.

💡 Beyond its formal regulatory function, the use test has reshaped how European insurers think about the relationship between modeling and management. Before Solvency II, many firms treated capital models as compliance artifacts maintained by actuarial teams with limited influence on commercial decisions. The use test forced a cultural shift: risk and actuarial functions gained seats at strategy tables, and model literacy became an expectation for board members — not just quantitative specialists. This principle has influenced regulatory thinking beyond Europe as well. Frameworks such as [[Definition:Insurance Capital Standard (ICS) | ICS]] under the International Association of Insurance Supervisors and elements of the [[Definition:Hong Kong Risk-based Capital (HKRBC) | Hong Kong RBC regime]] echo similar expectations that models used for capital determination should not be divorced from day-to-day risk management. For insurers, meeting the use test is ultimately about institutional integrity: ensuring that the numbers shaping regulatory outcomes are the same numbers shaping business reality.
