Wise Shares Plunge More Than 10% After Brussels Public Prosecutor Opens Money-Laundering Investigation Into Its European Entity
Shares in Wise, the London-listed cross-border payments processor, fell more than 10% after the Brussels Public Prosecutor's Office disclosed that it has been investigating Wise's European entity since 2025 over suspicious transactions totalling the equivalent of approximately $583 million. The investigation focuses on whether Wise Europe's services were used by international criminal organisations, with the prosecutor's office stating the probe is at an advanced stage and nearing completion. Wise is listed on the London Stock Exchange and the disclosure triggered a significant intraday sell-off. The investigation concerns the company's European operations, meaning the relevant regulatory and enforcement framework sits in Belgium, though Wise's primary listing and group structure are UK-based. The timing adds regulatory pressure to a company that has grown rapidly on the back of cheaper cross-border payment infrastructure and an international expansion strategy. No charges have been announced and the investigation remains ongoing.
Why this matters
For a listed company, an advanced-stage criminal investigation by a public prosecutor — even at a European subsidiary level — triggers immediate disclosure obligations and creates material uncertainty for shareholders. The more-than-10% share price drop reflects the market's reassessment of regulatory risk, potential remediation costs, and the reputational impact on a business whose core product is trust in payment processing. City law firms with white-collar crime, financial regulation, and public company advisory practices face demand simultaneously: internal investigations work, liaison with Belgian and potentially UK authorities, and advising the board on its disclosure obligations to the market. The 'why now' trigger is likely the prosecutor's own decision to make the investigation public, rather than any voluntary disclosure by Wise.
On the Ground
A trainee on the disclosure side of this matter would assist with drafting PDMR (person discharging managerial responsibilities) notification letters, reviewing the company's regulatory filing timetable, and preparing verification notes on any public statements to ensure factual accuracy. On the regulatory investigations side, they would assist with disclosure review and categorisation of documents relevant to the probe.
Interview prep
Soundbite
A criminal probe hitting a listed payments firm simultaneously activates securities law, white-collar crime, and AML compliance advisory mandates.
Question you might get
“What are the key disclosure obligations for a UK-listed company when a foreign regulator or prosecutor discloses an investigation into one of its subsidiaries, and how would the board's legal advisers approach the decision of whether and when to make a market announcement?”
Full answer
Wise's shares dropped more than 10% after Brussels prosecutors disclosed a money-laundering investigation into its European entity covering $583 million in suspicious transactions. For a listed company, this creates layered legal work: the board must assess its ongoing disclosure obligations under market rules, internal investigators must examine the scope of any compliance failures, and external counsel must manage parallel engagement with Belgian prosecutors and potentially the UK's Financial Conduct Authority. This reflects a broader trend of regulators scrutinising fintech payment platforms for anti-money laundering (AML) controls as those platforms scale rapidly across jurisdictions. The investigation's advanced stage suggests resolution — whether by prosecution, settlement, or clearance — could arrive relatively quickly, making this a live risk factor for Wise's institutional investors and a test case for how UK-listed fintechs manage cross-border enforcement.
