Definition:Prescribed capital requirement
📐 Prescribed capital requirement is a regulatory minimum amount of capital that an insurer or reinsurer must hold, calculated according to a formula or model specified by the supervising authority to ensure the company can absorb losses and continue meeting policyholder obligations under adverse conditions. The term is most closely associated with frameworks like Solvency II in Europe — where it is called the Solvency Capital Requirement — and Australia's APRA-administered regime, but virtually every insurance regulatory system imposes some version of a prescribed capital floor. It differs from an insurer's own internal economic capital assessment in that the methodology and calibration are set externally by the regulator, leaving less room for company-specific judgment.
⚙️ Calculation methods vary by jurisdiction but generally account for the major risk categories an insurer faces: underwriting risk, credit risk, market risk, and operational risk. Under Solvency II, for example, insurers can use a standard formula or, with supervisory approval, an internal model that reflects their specific risk profile. The prescribed requirement is calibrated to a confidence level — often 99.5% over a one-year horizon — meaning the capital should be sufficient to withstand a 1-in-200-year loss event. Falling below the requirement triggers a ladder of supervisory interventions: at the SCR level, the regulator demands a remediation plan; at the lower Minimum Capital Requirement, the company may face restrictions on new business or even license revocation.
🏗️ The prescribed capital requirement shapes strategic decisions well beyond the compliance department. Insurers factor the capital charge associated with each line of business, investment asset class, and reinsurance structure into their pricing, portfolio allocation, and growth plans. A product that generates attractive underwriting margins but consumes disproportionate capital may be less valuable on a risk-adjusted basis than a lower-margin line with modest capital requirements. For insurtechs seeking their own carrier licenses, understanding the prescribed requirement is essential from inception — it determines how much surplus must be raised before a single policy can be written and influences the pace at which the company can scale.
