2 min readWarningEBA reporting framework 4.2Updated 10 November 2026

None of the 1,472 values it checks in market risk: standardised approach for traded debt instruments can be negative (C 18.00, EBA rule v3766_s)

A warning in the own funds and capital requirements return (COREP own funds), on template C 18.00, market risk: standardised approach for traded debt instruments.

The rule in plain words

None of the values it checks in market risk: standardised approach for traded debt instruments can be negative.

EBA checks it for two columns: long and short. And for 32 rows, from maturity-based approach (0020) to rated nth-to default credit derivatives (0321). And on 23 sheets, from total (0001) to other (0025). That makes 1,472 checks. A failure names the one that failed.

How the Line4 Check report words itShow

The first of its checks, word for word as the report shows it when it fails. The others read the same, with their own column, row or sheet.

Long: > 7 <= 10 (> 5,7 <= 7,3 for coupon of less than 3%) years, Bulgarian Lev >= 0

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Look for a value with the wrong sign in these cells, such as an amount entered as a negative number.
  3. 03EBA compares the values exactly here: there is no rounding tolerance.
  4. 04It runs only when your filing indicators mark C 18.00 as reported.
  5. 05This is a warning. It does not stop the filing on its own, but your authority may ask you to explain it.

A worked example

The first of its checks, with simple numbers.

What the rule then expects

> 7 <= 10 (> 5,7 <= 7,3 for coupon of less than 3%) years, long must then be at least 0.

0Passes
-100Fails

A file that reports 0 passes. One that reports -100 fails, by 100.

The numbers are illustrative.
