The UK financial regulator has imposed a £21 million ($28.57 million) fine on digital bank Monzo for inadequate anti-money laundering (AML) controls and failures in preventing financial crime. The regulator highlighted Monzo's acceptance of customers with implausible information, including addresses listing prominent landmarks such as Buckingham Palace and 10 Downing Street. Separately, the Bank of England fined Mastercard's payment systems operator Vocalink £11.9 million ($16.2 million) for compliance failures related to risk management and governance standards. This marks the first fine levied by the Bank of England against a financial market infrastructure firm. Additionally, Barclays was fined £42 million ($56 million) by the UK watchdog for lapses in managing financial crime risks involving two clients, including one connected to one of Britain's largest money laundering cases. These enforcement actions underscore ongoing regulatory scrutiny over financial institutions' controls against financial crime in the UK.
