Risk-free rate curves and EIOPA data

Each month, EIOPA publishes a set of technical parameters used to produce the economic balance sheet, the SCR and the solvency ratio:

• Risk-free yield curves
• Correction for volatility
• Symmetrical equity adjustment

On this page, Addactis centralizes these various publications and puts these parameters into perspective with their levels in previous orders.

Every month, EIOPA constructs the risk-free yield curve from swap rates for maturities of 1 to 10 years, 12 years, 15 years and 20 years, from which a Credit Risk Adjustment (CRA) is deducted at a value of between 0.10% and 0.35%:

Risk Free Rate(RFR) = Swap Rate – Credit Risk Adjustment (CRA)

The yield curve is then constructed by interpolating maturities below the LLP (Last Liquid Point, 20 years), then extrapolated to converge towards the UFR (Ultimate Forward Rate) over a 60-year horizon, using the Smith Wilson method. The 2020 revision of Solvency II will eventually introduce a new extrapolation methodology.

Like the risk-free yield curve in the central scenario, the shocked yield curves according to the standard formula are supplied by EIOPA, which applies the downward and upward shocks provided for in Articles 166 and 167 of the Delegated Regulation to the risk-free yield curve, before adding the correction for volatility:

The shocks by maturity are as follows:

When interest rates are negative, downward shocks are zero.

The 2020 revision of Solvency II will modify the methods used to calculate interest rate shocks, to take better account of the specificities of low or even negative interest rate environments.

EIOPA determines the UFR annually from the sum of a real rate component and an expected inflation component (for the euro, this is the ECB’s inflation target of 2%). The annual variation of the UFR is limited to +/- 15 bps. UFR rises from 3.45% in 2023 to 3.30% in 2024.

Every month, EIOPA determines the euro currency volatility adjustment based on a portfolio representing the euro-denominated investments of European insurers. This portfolio includes sovereign and corporate bonds, as well as equities and real estate. The volatility adjustment is equal to the risk-adjusted spread of corporate and sovereign bonds.

First, a spread of the representative portfolio is calculated.

where :

• wgov and wcorp are the respective weights of sovereign and corporate bonds in the representative portfolio with wgov + wcorp + wequity + wproperty = 1
• Sgov and Scorp are the respective spreads of sovereign and corporate bonds.

The risk adjustment is then calculated as follows:

The risk-adjusted spread is equal to:

And finally, the VA of the currency is obtained by applying a corrective factor:

The VA euro has a national component that can be activated in the event of large spreads between a country’s representative portfolio and that of the European portfolio:

The volatility adjustment is then added to the rate for each maturity below the LLP (curve translation), then the rates for the following maturities are obtained by extrapolation to the UFR (Smith Wilson method).

The 2020 revision of Solvency II will change the way the volatility adjustment is calculated, making it specific to each company.

The symmetric adjustment (SA) modifies the level of equity shocks in the Standard Formula (type 1 at 39% and type 2 at 49%) to take account of market cycles. To determine it on a monthly basis, EIOPA has constructed an index replicating the average characteristics of assets held by insurers, and the symmetric adjustment is calculated from the difference between the last value of this index and the 3-year moving average of the index, according to the following formula:

where CI is the index level on the calculation date and AI is the weighted average of daily index values over the last 36 months.
The value of the symmetrical adjustment is between -10% and +10%.

The 2020 revision of Solvency II should widen the symmetrical adjustment corridor to +/- 13%.

The benchmark index is composed of :

The 2020 review of Solvency II is expected to bring a number of changes:

• the methodology used to construct the risk-free yield curve (notably extrapolation, with and without correction for volatility)
• to calculate the volatility correction
• at the terminals of the symmetrical fit
