UK-based money transfer service Wise is currently under investigation by Belgian authorities due to concerns that its platform may have been exploited for money laundering activities. The inquiry, which primarily examines Wise’s operations in Europe, has raised red flags regarding compliance with anti-money laundering regulations, leading to a notable dip in the company’s market value.
Investigation Overview
Belgian prosecutors have revealed that the investigation is nearing its conclusion, with a focus on approximately €500 million (£432 million) in suspicious transactions that span 30 European countries. A spokesperson from the Brussels prosecutors’ office confirmed that findings indicate potential misuse of Wise accounts for criminal purposes, suggesting failures in customer identification and compliance with existing legislation.
In a statement, Wise acknowledged its cooperation with the Brussels prosecutor’s office but noted, “no specific findings have been shared with us to date.” The company emphasized that it routinely engages with regulatory bodies and law enforcement, and that requests for information do not automatically imply wrongdoing.
Market Reaction
The news of the investigation has had a significant impact on Wise’s stock, which experienced a sharp decline of 17.5% following the reports. Analysts have expressed concern about the potential long-term implications of this scrutiny. Dan Coatsworth, head of markets at AJ Bell, remarked, “Until any findings are published, this issue is likely to hang like a heavy dark cloud over the business.” He added that if regulatory failures are confirmed, Wise could face substantial fines and damage to its brand reputation and customer trust.

A History of Regulatory Challenges
Wise has a track record of regulatory challenges. In 2024, the Financial Times reported that the company was instructed to enhance its compliance processes after the National Bank of Belgium identified issues related to proof of address for numerous customers. Furthermore, last year, Wise incurred fines totalling $4.2 million (£3.1 million) from six US states due to anti-money laundering compliance failures, and was fined $360,000 by Abu Dhabi’s financial services regulator in 2022. Wise has stated that it has taken steps to address these issues.
Despite these challenges, Wise maintains that it is committed to combating financial crime, noting that approximately one-third of its global workforce is dedicated to this cause. The company processes around 4.7 million transactions daily, boasting a customer base exceeding 19 million worldwide.
Conclusion
As the investigation unfolds, Wise’s future hangs in the balance. The outcome could have sweeping implications not only for the firm but also for its clients and investors. The possibility of hefty fines and the erosion of customer trust could reshape the landscape for Wise, which has built its reputation on facilitating secure and efficient cross-border transactions.

Why it Matters
The ongoing investigation into Wise underscores the increasing scrutiny financial institutions face in the battle against money laundering. As regulatory environments evolve, companies must remain vigilant in their compliance efforts to protect their reputation and customer trust. The outcome of this inquiry will not only influence Wise’s operational strategies but may also set a precedent for how similar companies manage regulatory challenges in the future.
