Warning: Scam letters pretending to be from IOSCO

The International Organization of Securities Commissions (IOSCO) wants to bring to the notice of whom it may concern that several scam letters are currently in circulation pretending to be from IOSCO. To our knowledge, two types of different scam letters have been sent:

  • Letters directly requesting recipients to pay a sum of money.
  • Emails which contain letters on behalf of the Financial Control Service of Investment Company of IOSCO requesting bank details, sometimes preceded by telephone calls.

None of these communications have been or are made by IOSCO, so PLEASE DO NOT MAKE ANY PAYMENT OR PROVIDE ANY BANKING INFORMATION OF ANY KIND if you receive any of these communications. This is a telematic fraud committed by third parties to obtain funds by simulating IOSCO communications.

IOSCO does not make unsolicited communications, including emails or phone calls, asking for payments or seeking detailed personal and financial information.

IOSCO’s email domain is “”; communications sent from other domains are not from IOSCO.
