Wise probed by Belgian prosecutors

Prosecutors in Belgium are reported to be investigating Wise in connection with roughly €500 million in suspicious transactions. Coverage on June 1, 2026, citing the Bureau of Investigative Journalism, said authorities are examining whether accounts at the fintech company were used to move proceeds linked to fraud, drug trafficking and corruption.

The reports said the Brussels prosecutor’s office is leading the scrutiny. The focus is on whether funds that may be tied to criminal activity passed through Wise accounts, rather than on individual customers or counterparties described in detail.

According to the reporting, the transactions under review are described as suspicious transfers. The articles did not state that prosecutors have brought charges, but highlighted that investigations are under way into potential money laundering and related offences.

News of the Belgian investigation prompted a sharp sell-off in Wise’s London-listed shares on June 1, 2026. By 09:00 GMT, the stock was down about 15%, according to coverage of the market reaction.

Some outlets reported that intraday declines in Wise shares reached as much as 19% following publication of the investigative reporting and confirmation of the prosecutor’s inquiry. The move reflected investor response to the regulatory scrutiny and uncertainty over potential outcomes.

The trading reaction placed Wise among the most actively watched financial stocks in London that day, as market participants digested the scale of the transfers under examination and the possible implications for the company.

In response to the reports, Wise issued a statement addressing the Belgian investigation. The company said it is working with the Brussels prosecutor to respond to queries and emphasised that it is cooperating with the authorities.

Wise stated that no specific findings have been shared with the company to date. It added that requests for information and suspicious-activity reports are, in its view, a normal part of operations for a financial institution and are not, by themselves, evidence of non-compliance or wrongdoing.

The company’s statement did not provide additional detail on the individual transactions involved or on any internal reviews. Wise instead focused on its cooperation with the prosecutor and on characterising information requests as routine elements of regulatory oversight.

The Bureau of Investigative Journalism’s work, cited across multiple outlets, framed the Belgian investigation in the context of wider efforts to track the movement of funds linked to organised crime and corruption. Wise’s role in the reports relates to whether its accounts were used to transfer proceeds tied to alleged criminal activity.

The articles highlighted that the approximately €500 million in questioned transactions form the basis of current scrutiny. They did not indicate that regulators in other jurisdictions had announced parallel actions tied to the same transfers as of June 1, 2026.

As of that date, the public record described an active prosecutor-led probe, a sharp negative market response, and a company stating that it is cooperating fully while awaiting any concrete findings from the Belgian authorities.
