Longevity risk and the Solvency II standard formula: a misaligned perspective

Kennisbank •

EU insurers are required to assess the appropriateness of the Solvency II Standard Formula (SII SF) for their portfolios. For longevity risk, this presents a challenge: the SII SF shock is calibrated using multi-year uncertainty, while the SCR is defined as a one-year Value-at-Risk of the Own Funds.

Longevity risk and the Solvency II standard formula: a misaligned perspective

This mismatch makes a proper appropriateness assessment impossible, calling for a revision of the longevity shock. Moreover, insurers would benefit from using more precise modelling techniques rather than relying on a fixed 20% shock.

Article 101(3) of the Solvency II Directive defines the Solvency Capital Requirement (SCR) as the Value-at-Risk of an insurer’s basic Own Funds over a one-year period, at a 99.5% confidence level. This means the SCR reflects potential changes in Own Funds due to adverse events within a one-year horizon. For longevity risk, the focus should therefore be on how changes in longevity assumptions or emerging experience over one year could impact Own Funds.
