Danske Bank's money-laundering scandal

Denmark's largest bank acquired Finland's Sampo Bank in 2007, inheriting a small Estonian branch that catered heavily to non-resident customers, many of them companies and individuals based in Russia and other former Soviet states. Between 2007 and 2015, roughly €200 billion in payments — about ten times Estonia's entire annual economic output — flowed through that single branch's non-resident portfolio via some 9.5 million individual transactions, with much of it bearing the hallmarks of money laundering rather than genuine trade or investment activity. Internal warnings about the branch's compliance failures reportedly reached Danske Bank's Copenhagen headquarters as early as 2007, but management did not act decisively until whistleblower reports and journalistic investigations forced the issue into the open around 2017-2018. Chief executive Thomas Borgen resigned in September 2018 as the scandal became public, and Danske Bank's stock lost roughly half its value that year. In 2022, the bank pleaded guilty to US bank-fraud charges tied to the case and agreed to forfeit around $2 billion, while the affair prompted a broader tightening of anti-money-laundering supervision across the EU's smaller banking centers.
