FCA fines for financial crime and money laundering failings

In December 2025 the Financial Conduct Authority (FCA) fined Nationwide Building Society £44,078,500 for weaknesses in its financial crime controls between October 2016 and July 2021. Nationwide did not keep customer due diligence and risk assessments up to date for its personal current account customers, and its transaction monitoring was ineffective; it also knew some customers were running businesses through personal accounts in breach of its terms but had no proper process to manage the extra risk. In one serious case the society missed chances to spot a customer using personal accounts to receive over £27m in fraudulent Covid furlough payments. Nationwide, which had reported the problems itself and cooperated, agreed to settle and received a 30% discount; the fine would otherwise have been £62,969,297.

In July 2025 the FCA fined Monzo Bank £21,091,300 for inadequate anti-financial crime systems and controls between October 2018 and August 2020, and for repeatedly breaching a requirement it had agreed with the regulator (a "VREQ") not to open accounts for high-risk customers between August 2020 and June 2022. Monzo's customer base grew almost tenfold, from around 600,000 in 2018 to over 5.8 million in 2022, but its onboarding checks, customer risk assessments and transaction monitoring did not keep pace: customers were able to open accounts using obviously implausible addresses such as Buckingham Palace, and more than 34,000 high-risk customers were signed up while the restriction was in force. Monzo agreed to settle and qualified for a 30% discount; without it the fine would have been £30,130,475.

The FCA fined Starling Bank £28,959,426 for failings in its financial crime systems and controls between December 2019 and November 2023 — the regulator's first fine against a digital challenger bank. Starling's customer numbers grew from about 43,000 in 2017 to 3.6 million in 2023 but its safeguards did not keep up: in January 2023 it discovered that since 2017 its automated screening had been checking customers against only a fraction of the full financial sanctions list, and it breached a requirement agreed with the FCA in 2021 not to open accounts for high-risk customers by opening over 54,000 accounts for around 49,000 such customers between September 2021 and November 2023. The FCA described the bank's controls as "shockingly lax". Starling agreed to settle and received a 30% discount; the fine would otherwise have been £40,959,426.

The FCA fined Barclays Bank £72,069,400 in November 2015 over a £1.88 billion structured investment it arranged in 2011 and 2012 for a group of ultra-wealthy clients who were politically exposed persons, and who should therefore have been subject to enhanced checks. Barclays nicknamed it an "elephant deal" because of its size, but rather than applying its normal anti-money-laundering procedures it cut corners to take the clients on quickly and keep the business. The FCA found Barclays failed to act with due skill, care and diligence between May 2011 and November 2014. The penalty comprised £52.3 million of revenue the bank earned from the deal plus a £19.8 million fine; Barclays settled early for a 30% discount, without which the total would have been £80,542,000. At the time it was the largest financial crime penalty ever imposed by the FCA or its predecessor.

On 9 August 2010, the Financial Services Authority (the FCA's predecessor) fined NatWest Markets Plc £5,600,000.

On 14 February 2007, the Financial Services Authority (the FCA's predecessor) fined Nationwide Building Society £980,000.

On 12 January 2004, the Financial Services Authority (the FCA's predecessor) fined Bank of Scotland plc £1,250,000.

On 12 December 2002, the Financial Services Authority (the FCA's predecessor) fined NatWest Markets Plc £750,000.
