Concerns have emerged regarding Wise, the prominent UK-based money transfer service, as Belgian prosecutors investigate potential money laundering activities involving the platform. The inquiry focuses on Wise’s European operations and reportedly involves suspicious transactions amounting to approximately €500 million (£432 million) across 30 countries. Following the announcement, Wise’s shares plummeted by 17.5%, significantly impacting its market valuation.
Investigation Details
Belgian authorities have confirmed that their investigation into Wise’s activities is nearing completion, although no specific findings have been disclosed to the company. A spokesperson for the Brussels prosecutor’s office indicated that the inquiry primarily examines the misuse of Wise accounts for illicit purposes, highlighting potential failures in adhering to anti-money laundering (AML) regulations. The spokesperson emphasised concerns over Wise’s ability to effectively identify its customers and monitor their activities.
In response to these developments, Wise stated that it is cooperating with the Brussels prosecutor’s office, asserting that it routinely engages with regulatory bodies and law enforcement. The company maintained that requests for information from such authorities are standard practice and do not inherently indicate non-compliance or wrongdoing.
Financial Impact and Market Reactions
The news of the investigation has had a dramatic effect on Wise’s market position. Analysts reported that the company saw a reduction of more than £1 billion in its market value as apprehension surrounding the allegations took hold. Dan Coatsworth, head of markets at AJ Bell, noted that the situation casts a “heavy dark cloud” over the business, especially given its previous regulatory challenges. Coatsworth cautioned that if oversight failures are confirmed, Wise may face substantial fines and, more critically, damage to customer trust and brand reputation.

Wise, which has been in operation since 2011, serves over 19 million customers globally and processes approximately 4.7 million transactions daily. Despite the current challenges, the company has previously taken steps to address regulatory concerns, including a $4.2 million (£3.1 million) fine from six US states for AML compliance violations last year and a $360,000 penalty from Abu Dhabi’s financial services regulator in 2022.
Historical Context and Ongoing Compliance Efforts
The investigation is not Wise’s first encounter with regulatory scrutiny. Reports from the Financial Times revealed that in 2024, the National Bank of Belgium directed Wise to enhance its compliance processes after discovering that the company lacked proof of address for a significant number of customers. Wise has publicly acknowledged the reality that financial institutions face increasingly sophisticated criminal activities attempting to exploit their platforms. The company has dedicated around a third of its workforce to combatting financial crime.
Wise’s dual listing on the London Stock Exchange and the US Nasdaq, following a recent shift of its primary listing to the latter, reflects its ambition to expand its global footprint. However, the current investigation could have lasting implications for its operations in Europe and beyond.
Why it Matters
The ongoing investigation into Wise underscores the critical importance of robust compliance frameworks within financial institutions, particularly those engaged in cross-border transactions. As regulatory scrutiny intensifies worldwide, companies like Wise must navigate complex legal landscapes while maintaining customer trust. The potential fallout from this investigation could reshape the company’s reputation and its operational strategies, emphasising the need for transparency and diligence in financial practices.
