1 min readBlockingEBA reporting framework 4.2Updated 10 November 2026

Combined buffer requirement must equal a sum of five terms (EBA rule v6290_m)

A blocking check in the own funds and capital requirements return (COREP own funds), on template C 04.00, capital adequacy - Memorandum items.

The rule in plain words

Combined buffer requirement must equal these five worked out:

  • Capital conservation buffer
  • Conservation buffer due to macro-prudential or systemic risk identified at the level of a Member State
  • Institution specific countercyclical capital buffer
  • Systemic risk buffer
  • The larger of global Systemically Important institution buffer and other Systemically Important institution buffer

All the values are in the amount column (0010) of C 04.00.

How the Line4 Check report words itShow

Word for word as the report shows it when the rule fails.

Combined Buffer Requirement = Capital conservation buffer + Conservation buffer due to macro-prudential or systemic risk identified at the level of a Member State + Institution specific countercyclical capital buffer + Systemic risk buffer + the larger of Global Systemically Important Institution buffer and Other Systemically Important Institution buffer

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Work out both sides from your file, as the rule in plain words sets out, and compare them.
  3. 03EBA allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark C 04.00 as reported.
  5. 05This is a blocking check. A filing that fails it is normally rejected, so fix it before you submit.
