You can check international warnings and alerts via the International Organization of Securities Commissions’ investor alerts portal and overseas regulators’ websites.
The International Organization of Securities Commissions (IOSCO) receives alerts and warnings from its members about businesses not authorised to provide investment services in the jurisdiction which issued the alert or warning. The alerts and warnings included in the list are provided by IOSCO members on a voluntary basis, so may not be a complete list of all alerts and warnings from all IOSCO members.
