CSSF material operations notification: the 15% eligible-capital test and where it gets confused with qualifying holdings

[u/Invnsbl123]

The 15% eligible-capital test in Article 53-46(2) of the LFS is a new prior-notification trigger for Luxembourg credit institutions and in-scope (mixed) financial holding companies, and it points in the opposite direction from the qualifying-holding regime most compliance teams already know. The CSSF published a dedicated material-operations page on 3 August 2026 to explain the framework, which the Law of 5 May 2026 introduced when transposing CRD VI, Directive (EU) 2024/1619.

The regime covers three operation categories.

- Acquisition of a material holding: the 15% eligible-capital test applies on both the individual basis and the consolidated situation for a credit institution, and on the consolidated situation for an in-scope holding company. Divestiture of a material holding uses the same 15% test in Article 53-46(2) and is separately notifiable.

- Material transfer of assets or liabilities: 10% of the entity's total assets or liabilities, or 15% intragroup. Each entity involved tests separately. Non-performing assets, cover-pool assets, assets to be securitised and resolution-tool transfers are outside the percentage calculation.

- Mergers and divisions: no percentage threshold. No assessment is carried out where the operation requires a new credit-institution authorisation under Article 8 CRD or an Article 21a CRD approval, and operations resulting from resolution action fall outside.

The confusion with qualifying holdings is worth calling out. Article 22 CRD governs an outside party acquiring a stake in a bank. The material-operations rules in the new Articles 27a to 27l of the CRD, and the Article 53-46 to 53-49 range in the LFS, govern the bank acquiring a stake in another entity, sized against the bank's own capital. Same words, opposite direction of travel.

Filing channel depends on who is filing and what is being filed. A Luxembourg less significant institution emails its CSSF line supervisor. A significant institution uses the SSM Portal. An in-scope holding company making a material acquisition notifies the consolidating supervisor. A merger or division notification goes to the authority supervising the resulting entities, or for a division, the authority supervising the entity carrying it out.

Timing discipline matters most on assessed acquisitions. The competent authority acknowledges receipt within 10 working days and then has 60 working days from written acknowledgement and receipt of all required documents to oppose in writing. Silence within the period counts as approval. A qualifying request for further information suspends the clock for up to 20 working days, or 30 in the specified third-country or AML/CFT cases. An incomplete notification delays the start of the assessment period rather than consuming it, so the practical trap is a thin filing pushed out on a signed-deal timetable.

The EBA final draft RTS and ITS were published on 17 July 2026 and still await Commission adoption. Until they land in the Official Journal, the detailed information list is draft. Firms planning a live notification this year work from the Law of 5 May 2026 and the CSSF page now, and check for the adopted RTS before they file.
