Symmetric adjustment of the equity capital charge under Solvency II - Analysis and forecast for 2020 and 2021

By 3 minute read

The Solvency II capital charge is an important aspect in portfolio construction and asset allocation for insurance companies. For equities a capital charge with a variable component – the symmetric adjustment – is used. This article explains the calculation of the symmetric adjustment and also makes a projection for the remainder of 2020 and 2021. This projection shows that the symmetric adjustment may well remain negative in the coming period, making equities - ceteris paribus - relatively attractive from a capital point of view.

Solvency II is the regulatory framework for European insurance companies since January 1, 2016. The solvency capital requirement (SCR) is a crucial element under Solvency II. Because Solvency II is a risk-based framework, riskier assets are typically charged with a higher SCR than less risky assets. An example is given below for different asset classes.

We consider the stand-alone SCR here, so before diversification and tax effects. We also assume that interest rate and currency risk are hedged on the overall balance sheet. This figure shows that the SCR is zero for euro sovereign bonds (and euro government related bonds) and very low for cash or money market investments. The SCR increases for bonds with longer maturities or lower ratings.

For more risky categories (like equities), the SCR is not fixed but changes over time. The maximum deviation in SCR from the base value is 10%-points. In simple terms, this means that in a bull market the SCR for equities goes up, while the SCR goes down in a bear market. This mechanism – known as the symmetric equity adjustment – makes equities more capital expensive under Solvency II in an upward market and vice versa. The idea is to suppress pro-cyclical investment behavior of insurance companies by making equities less attractive in bull markets and vice versa.

The following figure presents the official level of the symmetric adjustment as published by EIOPA.

This adjustment is very volatile, as is shown in the figure. It can go from one extreme point to another in only one year, as was the case in 2000-2001 and in 2007-2008. In other words, the amount of capital that an investor needs to set aside for equity investments can vary significantly from one year to the next. In relative terms, the capital charge for equity can vary by almost 70% for equity type I (50% for equity type II).

Currently (at the end of December 2019), the symmetric adjustment is equal to -0.08%. From this starting point, we have made a forecast of the symmetric adjustment for 2020 and 2021. We mainly see a negative symmetric adjustment, even in our positive macroeconomic scenario. This is due to the relatively low equity returns predicted in our outlook for 2020 and 2021.

A summary of the findings:

  • The symmetric equity mechanism is very volatile over time and currently close to zero (-0.08%)
  • For 2020 and 2021, we mainly expect a negative sign of the symmetric adjustment, due to low expected equity returns in our economic outlook
  • The capital charge for equities may thus well drift below its base level in the coming period, making this asset class relatively inexpensive from a capital point of view.
