Other non-trading non-derivative financial assets, trading book cannot be negative (EBA rule v6566_s)

A check in the own funds and capital requirements return (COREP own funds), on template C 32.01, prudent valuation, fair-valued assets and liabilities.

EBA switched this rule off for filings submitted from 17 March 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

Other non-trading non-derivative financial assets, trading book cannot be negative.

EBA writes it out 132 times. These words are for the first; the others are the same rule on other cells.
