Solvency capital requirement - for undertakings on standard formula and solvency capital requirement - market risk: a total must equal the sum of its parts (S.25.01, S.26.01, EIOPA rule BV1157)

A warning on the solvency capital requirement - for undertakings on standard formula (S.25.01) and solvency capital requirement - market risk (S.26.01) templates, in the annual solo (ARS), annual group (ARG) and annual branch (ARB) returns.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

The item "Total market risk" reported in Solvency Capital Requirement - Market risk (S.26.01), should be equal to sum of interest risk, equity risk, property risk, spread risk, market risk concentrations, currency risk and diversification within market risk module

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs two of them (BV1157-1 and BV1157-2), and a failure names the one that failed.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04EIOPA allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark S.26.01 as reported.
  6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

A worked example

The first of its checks, with simple numbers.

Illustrative values
Interest rate risk, Gross solvency capital requirement1,200
Equity risk, Gross solvency capital requirement800
Property risk, Gross solvency capital requirement450
Spread risk, Gross solvency capital requirement300
Market risk concentrations, Gross solvency capital requirement150
Currency risk, Gross solvency capital requirement100
Diversification within market risk module, Gross solvency capital requirement60
Together3,060
What the rule then expects

Market risk, Gross solvency capital requirement must then be 3,060.

3,060Passes
3,160Fails

A file that reports 3,060 passes. One that reports 3,160 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

Which returns it applies to

Line4 Check runs it on annual solo (ARS), annual group (ARG) and annual branch (ARB) returns on EIOPA taxonomy 2.10.0. EIOPA applies it to annual group (ARG), annual ECB solo (AES), annual ECB branch (AEB), annual solo (ARS) and annual branch (ARB) returns, as a warning.

EIOPA's formula, for BV1157-2. Cells are written as {t: table, r: row, c: column}.

{t: S.26.01.01.02, r: R0800, z: Z0001} = {t: S.26.01.01.02, r: R0100, z: Z0001} + {t: S.26.01.01.02, r: R0200, z: Z0001} + {t: S.26.01.01.02, r: R0300, z: Z0001} + {t: S.26.01.01.02, r: R0400, z: Z0001} + {t: S.26.01.01.02, r: R0500, z: Z0001} + {t: S.26.01.01.02, r: R0600, z: Z0001} + {t: S.26.01.01.02, r: R0700, z: Z0001}

BV1157-1:

{t: S.26.01.04.02, r: R0800, z: Z0001} = {t: S.26.01.04.02, r: R0100, z: Z0001} + {t: S.26.01.04.02, r: R0200, z: Z0001} + {t: S.26.01.04.02, r: R0300, z: Z0001} + {t: S.26.01.04.02, r: R0400, z: Z0001} + {t: S.26.01.04.02, r: R0500, z: Z0001} + {t: S.26.01.04.02, r: R0600, z: Z0001} + {t: S.26.01.04.02, r: R0700, z: Z0001}

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
