Luxembourg Loi du 14 juillet 2023 — first-ever national FDI-screening mechanism (Mémorial A n° 411)

Mechanism

Luxembourg's Loi du 14 juillet 2023 portant mise en place d'un mécanisme national de filtrage des investissements directs étrangers susceptibles de porter atteinte à la sécurité ou à l'ordre public (published Mémorial A n° 411, 18 July 2023; in force 1 September 2023) establishes Luxembourg's first-ever horizontal FDI-screening framework under EU Regulation 2019/452.

Investor and transaction scope. The law covers direct or indirect acquisitions by non-EU investors (i.e., investors not established in another EU Member State — "third-country investors" per EU 2019/452 Article 2(2)) of ≥25% voting rights or equity in Luxembourg entities engaged in "critical activities" in Luxembourg. Portfolio investments and purely financial-return structures without influence over the entity are excluded.

Critical activities. Twelve categories of Article 4 coverage mirror the EU 2019/452 framework: critical infrastructure (energy, transport, water, health, communications, media, data-processing and storage, aerospace, defence, electoral and financial infrastructure, and sensitive facilities including related land/real estate); critical technologies and dual-use items (AI, robotics, semiconductors, cybersecurity, aerospace, defence-related tech, energy storage, quantum, nuclear, nanotechnology, biotechnology); critical input supplies (energy, raw materials, food security); access to sensitive information including personal data; freedom and pluralism of the media. The dual-use cross-reference operationally couples the FDI-screening perimeter to Luxembourg's existing dual-use export-control regime under Loi du 27 juin 2018 sur le contrôle de l'exportation.

Procedural architecture. Two-phase procedure: (1) pre-implementation notification to the Ministre de l'Économie → 2-month initial screening → decision; (2) if indicated, opening of a 60-day in-depth investigation → final Ministerial decision. The inter-ministerial Comité de filtrage (representatives from Ministry of Economy, Ministry of Foreign Affairs, Ministry of Finance, Ministry of State / SREL Service de Renseignement de l'État, and relevant sectoral ministries) advises throughout. The Minister of the Economy can approve, approve with conditions, or prohibit.

Mandatory pre-notification; sanctions. Failure to notify triggers voting-right suspension, administrative fines, and criminal sanctions under Article 12. Completion of a notifiable transaction without clearance is prohibited.

EU cooperation mechanism. Luxembourg implements information-sharing duties under EU 2019/452: the designated Single Point of Contact at the Ministry of Economy notifies the European Commission and other Member States of transactions under review, and receives equivalent notifications from peers.

Downstream implications

• Closes the EU member-state FDI-screening outlier trio: prior to this law Luxembourg was one of the very few EU-27 states without a national FDI-screening framework alongside Cyprus (which enacted Law 194(I)/2025 for entry into force April 2026) and Greece (Law 5202/2025). With LU now in force since September 2023, the EU FDI-screening coverage map approaches full saturation.
• Applies to Luxembourg's outsized financial-services and fund-management economy: Luxembourg hosts the world's second-largest investment-fund domicile (≈€5.6tn AuM as of 2024 per CSSF), 200+ banks, major fund-administrators (BlackRock, Vanguard, Amundi, JPMorgan), LuxSE, SES (satellite communications), ArcelorMittal (steel), RTL Group (media), Cargolux (cargo aviation). Non-EU acquisitions of these entities now require pre-notification and may be conditioned or blocked.
• Chinese and Russian investor flows: given Luxembourg's historical role as a destination for Chinese financial-sector capital (ICBC, Bank of China, CITIC subsidiaries) and historical Russian capital flows (largely terminated post-2022 sanctions), the regime provides the first horizontal statutory tool to review such transactions on security and public-order grounds.
• 2.5-year coverage gap closed: the law has been in force since 1 September 2023 but was not previously filed in this register; the gap is now closed.
• Anchors responds_to for future LU enforcement actions: any Luxembourg conditional approvals or prohibitions under this statute can be filed as enforcement actions responding to this slug.

Open questions

• No publicly reported LU Comité de filtrage decisions to date (as of May 2026) — the Ministry of Economy's two-year review note (cc.lu, September 2025) confirms the mechanism is operational but does not cite specific prohibited cases.
• How Luxembourg treats investment-fund-vehicle chains (PE fund → Luxembourg HoldCo → operating asset) remains to be tested; the SREL advisory role suggests national-security-intelligence review is available even for seemingly commercial structures.
