The provision of certain financial services by the operators has become a channel for criminals to launder their illegal incomes.In order to prevent and deter money laundering in the industry，Macao has promulgated laws and regulations as well as taken a number of measures compliant to international practices. For instance，casinos are required to file Currency Transaction Reports （CTRs） and Suspicious Transaction Report （STRs） to the regulatory bodies. The enforcement of anti-money laundering laws in Macao is，in general，satisfactory as no serious money laundering cases have been found.
