Solvency capital requirement - market risk: the format of a code or text (S.26.01, EIOPA rule BV569_1)

A warning on the solvency capital requirement - market risk template (S.26.01), 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 capital charge for bonds and loans reported in Solvency Capital Requirement - Market risk (S.26.01) should be equal to the loss in the value of assets minus liabilities (after the loss absorbing capacity of technical provisions) after the shock, with a minimum of zero

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 (BV569_1-1 and BV569_1-2), 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. 02Compare the code or text in your return with the format the rule sets out, character by character, including any prefix and any spaces.
  3. 03EIOPA allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark S.26.01 as reported.
  5. 05This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

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.
