Belgian prosecutors investigate Wise (WISE.L) over anti-money laundering failures

Belgian prosecutors said on June 1, 2026, they are investigating whether money transfer firm Wise (WISE.L) was used by criminal groups to launder funds. The probe focuses on suspected laundering of proceeds from fraud, corruption and drug trafficking. The London-listed fintech company, which processes roughly £30 billion in cross-border transactions annually, faces scrutiny over its anti-money laundering controls. The Belgian federal prosecutor’s office said the inquiry examines how Wise’s platform may have been exploited to move illicit funds, though it provided no specific transaction volumes or timeframes. Wise’s shares fell 4.2% in London trading following the disclosure. The company did not immediately respond to requests for comment.
