Monzo Bank
London, United Kingdom
K. Financial Conduct Authority disclosed a £21 million penalty against Monzo Bank on Jul 08, 2025, citing lax anti-money laundering controls and repeated breaches of a previously imposed restriction. In 2020, amid rapid growth in Monzo's customer base, regulators uncovered systemic compliance deficiencies and barred the London-based digital lender from opening accounts for clients deemed inherently high-risk.
Monzo failed to comply, opening accounts for more than 34,000 high-risk customers between August 2020 and June 2022. The bank onboarded customers using limited and, in some cases, implausible information, including well-known London landmarks listed as home addresses. The FCA fined Starling Bank £29 million over similar violations in October 2024.
