Wise shares fall after reports that Belgian authorities are investigating the money transfer fintech over money-laundering concerns. The Financial Times and Channel NewsAsia both link the share decline to a probe by a Belgian prosecutor, indicating that the action is tied to possible violations related to financial crime and compliance. The reporting describes the move as an investigation rather than a finding of wrongdoing, and focuses on the market reaction to the announcement. While the sources emphasize the money-laundering element of the probe, neither report details specific alleged conduct or provides outcomes from the investigation. The information is presented as a development that has prompted investors to reassess risk and regulatory exposure for the company. The overall coverage indicates that Wise faces heightened scrutiny in Belgium as the prosecutor reviews the matter, and that the immediate impact is reflected in the company’s share price.
