Wise Shares Slide as Money Laundering Probe Raises Fresh Questions
EBM Newsdesk Analysis — By Anthiony Gill
Wise has spent a decade positioning itself as the fintech that does cross-border payments properly — transparent fees, fair exchange rates, no hidden charges. On Monday, that brand proposition collided with a criminal investigation that sent its shares down as much as 19% in London trading before recovering to close down around 8%. The numbers involved are not small, the jurisdiction is not peripheral, and this is not the first time Wise’s compliance architecture has attracted serious regulatory attention.
Wise confirmed it is answering queries from prosecutors in Belgium, where authorities are investigating concerns that its accounts have been used to launder proceeds of fraud, drug trafficking and corruption. According to Reuters, the Brussels Public Prosecutor’s Office is investigating Wise’s European entity in cases involving more than half a billion euros — approximately $582.5 million — in suspicious transactions. The investigation began last year and is nearing completion, with prosecutors finalising a direct summons before the criminal court. mexcBitMEX
This Is the Third Jurisdiction. That Is the Problem.
A single regulatory investigation can be explained as bad luck or a compliance gap that has since been addressed. Three jurisdictions moving against the same company’s anti-money laundering controls within twelve months is a pattern — and patterns are what destroy fintech valuations.
The Belgian investigation makes Belgium the third authority to fault Wise’s anti-money laundering controls, after US state regulators and the Consumer Financial Protection Bureau both acted last year. In July 2025, Massachusetts joined a multistate enforcement action against Wise US for violations of the Bank Secrecy Act and anti-money laundering regulations. The CFPB followed with its own action shortly after. Yahoo Finance
At the centre of the Belgian case is Wise Europe — the Belgian-licensed entity through which Wise serves customers across the European continent. Brussels prosecutors have been investigating Wise Europe since 2025. The federal police’s organised crime unit, known as DJSOC, is handling the investigation, which concerns compliance issues related to anti-money laundering regulations across more than 30 European countries.

The prosecutorial route being taken matters commercially. A direct summons — the mechanism prosecutors are finalising — takes the case directly to criminal court without an investigating judge. It is a more commonly used route in Belgium than in other jurisdictions, but its use here signals that prosecutors believe they have sufficient evidence to proceed without further investigation. That is a meaningfully different posture from an inquiry that is still gathering information.
The Compliance History That Makes This Harder to Dismiss
Wise’s compliance record has been showing stress fractures for several years. As we reported in our analysis of how European fintech companies are navigating the intersection of rapid growth and regulatory scrutiny, the tension between scaling cross-border payment infrastructure and maintaining the compliance controls that regulators require is one of the defining commercial challenges in the sector.
Wise’s specific history on this question is instructive. A review by the National Bank of Belgium as far back as 2022 found that the company had failed to provide proof of address for hundreds of thousands of customers — a basic KYC requirement. The UAE fined Wise in 2022 for inadequate due diligence on high-risk customers. The UK’s Office of Financial Sanctions Implementation found compliance failures the following year. The pattern of regulatory action stretching across multiple jurisdictions and multiple years makes it considerably more difficult for Wise’s management to present the Belgian investigation as an isolated incident.
For European investors and asset managers, the compliance history is the most commercially significant element of the story — more significant, arguably, than the specific Belgian investigation itself. A company with a clean prior record facing its first regulatory inquiry is a recoverable situation. A company facing criminal court proceedings in its primary European operating entity while simultaneously managing enforcement actions in the United States is navigating a materially different risk profile.
What It Means for European Fintech More Broadly
The Wise investigation arrives at a sensitive moment for European fintech regulation. As we reported in our coverage of how the EU’s regulatory framework is reshaping financial services across the continent, Brussels has been actively tightening its approach to financial crime compliance following the Wirecard collapse — which demonstrated that regulatory gaps in the European financial system could be exploited at scale before authorities intervened.
The scale of the suspicious transactions under review — more than €500 million — will intensify that regulatory focus. European authorities have been trying to crack down on illicit finance following the collapse of Wirecard and a 2019 money laundering scandal. Wise’s Belgian entity processing hundreds of criminal files worth half a billion euros in suspicious transactions is precisely the scenario that European regulators have been working to prevent — and the political pressure to act decisively will be significant.

According to Bloomberg, Wise stated it takes its legal and compliance obligations seriously and is cooperating fully with the Belgian authorities. The company also noted that being subject to an investigation does not imply guilt. Both statements are correct and both are legally necessary. Neither materially changes the commercial reality that a criminal summons in Belgium, combined with concurrent US enforcement actions, represents a level of simultaneous regulatory pressure that will affect customer confidence, institutional partnerships and the company’s ability to expand its licensed operations across European jurisdictions.
The IPO Timing Problem
The Wise investigation also carries implications for the broader European fintech IPO environment. As we explored in our analysis of the Monzo IPO and the competitive dynamics reshaping European digital banking, the European fintech sector was building toward a wave of significant listings in 2026 and 2027. A high-profile criminal investigation into one of the sector’s most recognised names — at the moment that institutional investors are forming their views on fintech risk — is an unwelcome development for every company in the pipeline.
The Wise story is not finished. The investigation is nearing completion rather than just beginning, which means a resolution — in whatever form it takes — may come within months rather than years. How Wise manages that resolution, and what terms prosecutors ultimately seek, will determine whether Monday’s share price decline was an overreaction or an underpricing of the risk ahead.
