Wise's stock price plummeted due to its involvement in an EU anti-money laundering investigation.

On June 1st, City AM reported that cross-border remittance platform Wise is under investigation by Belgian prosecutors for allegedly violating anti-money laundering regulations. This investigation stems from Wise's accounts being implicated in the alleged transfer of approximately €500 million in illicit funds. The probe involves hundreds of international criminal cooperation requests from over 30 European countries. Following the announcement, Wise's stock price dropped by approximately 15% to 796 pence in London trading. The investigation specifically targets Wise's European operations managed by its Brussels office, with approximately 3 million UK users excluded from this scope. Wise has stated its cooperation with Brussels prosecutors and regulatory and law enforcement agencies, highlighting that about one-third of its employees are dedicated to combating financial crime. Previously, in 2025, Wise's US subsidiary was fined a total of $4.2 million by regulators in six states due to compliance deficiencies.
