Concept
Banque Internationale à Luxembourg (BIL) is Luxembourg's oldest bank (1856), a universal bank with a strong private banking arm. Type: a systemically important bank supervised by the ECB (SSM) and the CSSF; ~90% owned by Hong Kong's Legend Holdings (since 2018, at a €1.48bn valuation), ~10% by the Luxembourg state. The CEO since May 2024 is Jeffrey Dentzer. Ratings: S&P A–/Negative, Moody's A2/Stable. Per Legend Holdings' 2026 interim report, it held 89.98% of BIL at 30 June 2026.
History and evolution
Founded on 8 March 1856; it co-financed the creation of ARBED and Clearstream and underwrote the first eurobond (1963). The Dexia era ended in rescue: in 2012 the bank was sold to Precision Capital (90%) and the Luxembourg state (10%). Legend Holdings bought the stake in 2018. Perimeter reshaping 2015–2026: Singapore closed (2015), Denmark transferred to Ringkjøbing Landbobank (2021), the DIFC branch licence withdrawn (2021), the Hong Kong office closed (January 2025), fund administrator BIL Manage Invest sold to Waystone (completed October 2025) and the Belair House family office closed (2025); at the same time a Paris private-banking branch opened on 3 July 2025.
Assets under management reached €50.1bn at end-2025 (+7%), with net income of €210m (+24%); CET1 is 14.46%.
Regulation
- ECB / CSSF — BIL S.A., Luxembourg;
- FINMA — Banque Internationale à Luxembourg (Suisse) SA (Zurich, Geneva, Lugano; since 1985);
- the Paris branch operates under BIL S.A.'s EU passport; the Beijing representative office conducts no banking.
Source of funds and compliance
The EU standard applies: identification, beneficial owners, source of funds and source of wealth, CRS/FATCA. Dated episodes: in March 2020 the CSSF fined BIL €4.6m for AML process weaknesses identified in 2017–2018 inspections (the bank stated no money-laundering activity was identified and completed a remediation program); in 2024 investigators linked Dexia-era BIL accounts to the embezzlement from the International Bank of Azerbaijan — no new sanction followed.

Q/A
Entry and geography
What minimum capital does BIL require?
No official threshold is published. Industry references cite around €1 million for Luxembourg private banking; for BIL Suisse entrepreneur relationships benchmarks run higher (US$3–5m combined). Admission is individual.
Who owns BIL?
Legend Holdings, listed in Hong Kong, held 89.98% of BIL at 30 June 2026 per its interim report; the Luxembourg state holds the rest. For clients the shareholder question is one of strategy, not asset safety: the bank is profitable and systemically important.
What does the deposit guarantee cover?
Luxembourg — FGDL €100,000 with a 7-working-day payout; Switzerland — esisuisse CHF 100,000. Custody securities remain the client's property and are returned to the owner in a bank failure.
Supervisory backdrop
What was the 2020 CSSF fine?
€4.6m for AML process weaknesses found in 2017–2018 inspections. The bank stated no money-laundering activity was identified and completed a remediation program: a new risk appetite, scoring, hiring. The sanction concerned processes, not client assets.
Did BIL accounts feature in the Azerbaijani case?
The 2024 OCCRP investigation linked Dexia-era BIL accounts (pre-2012) to embezzlement from the International Bank of Azerbaijan; the Luxembourg case indicts an individual. No new sanctions against the bank followed; BIL reaffirmed its compliance commitment.
