چکیده

This paper examines why a financial entity’s solvency capital estimation might be underestimated if the total amount required is obtained directly from a risk measurement. Using Monte Carlo simulation we show that, in some instances, a common risk measure such as Value-at-Risk is not subadditive when certain dependence structures are considered. Higher risk evaluations are obtained for independence between random variables than those obtained in the case of comonotonicity. The paper stresses, therefore, the relationship between dependence structures and capital estimation.

The fundamental definition of the Solvency Capital Requirement in Solvency II

It is essential for insurance regulation to have a clear picture of the risk measures that are used. We compare different mathematical interpretations of the Solvency Capital Requirement (SCR) definition that can be found in the literature. We introduce a mathematical modeling framework that allows us to make a mathematically rigorous comparison. The paper shows similarities, differences, and p...

Solvency II solvency capital requirement for life insurance companies based on expected shortfall

This paper examines the consequences for a life annuity insurance company if the solvency II solvency capital requirements (SCR) are calibrated based on expected shortfall (ES) instead of value-at-risk (VaR). We focus on the risk modules of the SCRs for the three risk classes equity risk, interest rate risk and longevity risk. The stress scenarios are determined using the calibration method pro...

Risk and Determination of Solvency Capital in the Solvency 2 Framework

This paper investigates the robustness of the Solvency Capital Requirement (SCR) when a log-normal reference model is slightly disturbed by the heaviness of its tail distribution. It is shown that situations with “almost” lognormal data and a rather important variation between the “disturbed” SCR and the reference SCR can be built. The consequences of the estimation errors on the level of the S...

Analysis of the Solvency II Standard Model Approach to Longevity Risk

In general, the capital requirement under Solvency II is determined as the 99.5% Value-at-Risk of the Available Capital. In the standard model’s longevity risk module, this Value-at-Risk is approximated by the change in Net Asset Value due to a pre-specified longevity shock which assumes a 25% reduction of mortality rates for all ages. We analyze the adequacy of this shock by comparing the resu...
