Hedging debt securities, duration cannot be negative (EBA rule v23166_s)

A check in the interest rate risk in the banking book return (IRRBB), on template J 02.00, breakdown of sensitivity estimates.

EBA switched this rule off for filings submitted from 10 June 2026, in a quarterly update to its list of validation rules. It no longer applies, so a failure here does not count, and Line4 Check does not run it.

The rule in plain words

Hedging debt securities, duration cannot be negative.

EBA writes it out 51 times. These words are for the first; the others are the same rule on other cells.

And 50 more, the same formula for the other cells it covers.

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