Compare the best brokers, banks, crypto exchanges and forex brokers in Luxembourg for 2026. Only CSSF-regulated platforms reviewed.
Luxembourg is Europe's premier investment fund domicile and a global financial centre. The Commission de Surveillance du Secteur Financier (CSSF) regulates banks, investment firms, UCITS funds, and alternative funds. Luxembourg hosts over €5 trillion in assets under management — more than any other EU country — making it the world's second-largest fund centre after the United States.
The Luxembourg Système d'indemnisation des investisseurs Luxembourg (SIIL) protects investors up to €20,000 per investor for investment claims. Bank deposits are covered up to €100,000. Bitstamp, one of Europe's oldest crypto exchanges, is regulated by the CSSF in Luxembourg — making it one of the few crypto exchanges with direct EU banking oversight.
Luxembourg has favourable tax treatment for investment income: capital gains on shares are exempt from tax if held for more than 6 months (for non-speculative holdings below 10% shareholding). Dividend income is taxed at progressive rates, but a 50% exemption applies to dividends from EU-qualifying companies. International platforms like Interactive Brokers, Swissquote, and Saxo Bank have operations in Luxembourg.
All platforms listed for Luxembourg are regulated by Commission de Surveillance du Secteur Financier (CSSF) or are passported into Luxembourg under EU MiFID II / ESMA rules. We do not list unregulated or offshore brokers.
