Definition:Solvency capital requirement (SCR)
📊 Solvency capital requirement (SCR) is the amount of eligible capital an insurer or reinsurer must hold under the Solvency II framework to absorb significant unexpected losses over a one-year time horizon with a 99.5 percent confidence level — effectively calibrated to withstand a one-in-200-year adverse event. It represents the core quantitative pillar of European solvency regulation and serves as the trigger point for heightened supervisory intervention if breached.
🔧 Firms can calculate their SCR using either the standard formula prescribed by the European Insurance and Occupational Pensions Authority or an internal model approved by their national supervisor. The standard formula aggregates capital charges across defined risk modules — underwriting risk (split into life, non-life, and health sub-modules), market risk, credit risk, and operational risk — then applies correlation matrices to reflect diversification benefits. Internal models, by contrast, let firms use their own data and methodologies, often producing a more tailored (and sometimes lower) capital figure. Regardless of approach, the SCR must be recalculated at least annually and reported to the supervisor, with any material change in risk profile triggering an ad hoc reassessment.
⚖️ Breaching the SCR does not immediately force an insurer to cease writing business, but it does set a demanding supervisory clock in motion. The firm must submit a realistic recovery plan and restore its capital position within a timeframe agreed with the regulator — typically no longer than six months, extendable to nine in exceptional market conditions. For CFOs and CROs, managing the SCR ratio (own funds divided by the SCR) has become a central strategic metric, influencing decisions on reinsurance purchasing, asset-liability management, product pricing, and dividend policy. Investors and rating agencies also monitor SCR ratios closely, making them a de facto market signal of an insurer's financial resilience.
