Open derivatives: a cell must be left empty (S.08.01, EIOPA rule BV809)

A blocking check on the open derivatives template (S.08.01), in the quarterly solo (QRS), quarterly group (QRG) and quarterly branch (QRB) 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 "Swap received" in Open Derivatives (S.08.01) is only applicable to interest rate swaps, currency swaps and to interest rate and currency swaps (CIC = ##D1, ##D2, ##D3)

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 (BV809-1 and BV809-2), 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. 02Remove the value from this cell where the rule applies. A 0 is a value too, so leave the cell out of the return altogether.
  3. 03It runs only when your filing indicators mark S.08.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

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.
