1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

None of the 24 values it checks in trading book and market risk thresholds (TBT) can be negative (C 90.00, EBA rule v10240_s)

A warning in the market risk return (FRTB), on template C 90.00, trading book and market risk thresholds (TBT).

The rule in plain words

None of the values it checks in trading book and market risk thresholds (TBT) can be negative.

EBA checks it for eight columns: on - and off - balance sheet business subject to market risk, trading book, total, in % of total assets (0040), positions subject to foreign exchange risk, positions subject to commodities risk, in % of total assets (0070), and total assets. And for three rows: month 3, month 2 and month 1. That makes 24 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.

Positions subject to foreign exchange risk: Month 3 >= 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 90.00 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.

What the rule then expects

Month 3, positions subject to foreign exchange risk must then be at least 0.

-100Fails

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

Checks like this one, run at the point of submission, are the first step to real-time supervision.
