The role of the Special Investigation Commission on fighting money laundering and terrorism financing is to apply the laws and regulations in force. This is done by fostering interagency and global cooperation for fighting domestic and international money-laundering and terrorism financing crimes.  

The SIC investigates reported suspicious transactions, with a proactive approach in applying the provisions of Law 44. Cases considered by the SIC as money laundering and terrorism financing are deferred to the judicial authorities and to other concerned parties, as specified in the said law. Consequently, banking secrecy is lifted on the accounts involved.

Money-laundering operations may occur in any business especially: 

· Banks 
· Other financial institutions (insurance, mutual funds, etc.) 
· Money exchange firms 
· Antique dealers 
· Real estate concerns 
· Jewelry dealers
