Investment Scams in Portugal
Unlicensed investment platforms and boiler-room operations targeting Portuguese savers and expats through social-media ads and cold calls.

Last reviewed: 1 June 2026
Portugal's growing digital financial adoption and relatively low average investment familiarity create opportunities for fraudulent investment schemes. Fraudsters advertise on social media using fabricated endorsements by Portuguese public figures and operate unlicensed trading platforms denominated in EUR.
CMVM (Comissão do Mercado de Valores Mobiliários) and Banco de Portugal maintain warning lists and coordinate with police, but many operations run from non-EU jurisdictions. Victims include both Portuguese nationals and foreign residents attracted to Portugal's NHR (Non-Habitual Resident) tax regime.
How this scam works on Portugal
Social-media adverts feature fabricated celebrity endorsements for automated trading systems available in Portuguese. After submitting contact details, a broker calls back with fluent Portuguese, framing the product as a tax-efficient complement to NHR benefits.
Victims are guided through a SEPA or MB WAY deposit to an account labelled as 'segregated client funds'. Platform dashboards show EUR returns that outperform typical Portuguese savings accounts or treasury bonds.
Withdrawal requests trigger invented CMVM compliance fees, Portuguese IRS pre-payments, or 'anti-money-laundering holds' designed to extract further deposits.

Frequently asked questions
Are NHR residents in Portugal especially at risk of investment scams?
Scammers specifically target NHR residents because they are often unfamiliar with Portuguese financial regulations and may be looking for tax-efficient investment vehicles. The NHR regime is legitimate but does not offer any protection against investment fraud.
