What happened.

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.
