Money laundering has now been designated as a global crime, requiring the development of global strategies and policies to combat it. As a result, global courts should be established to hear all money-laundering cases and make informed decisions on punishments and penalties. The objective of this research is to assess the effectiveness of anti-money laundering (AML) regulations in Malaysian commercial banks. Customer record-keeping, suspicious transaction reporting, and employee training are three predictors that have been expected to affect money-laundering activities. Simple random sampling was used to pick the respondents from bank employees in the Klang Valley area. A total of 94 (94%) questionnaires were returned, and the data were analysed using descriptive and multiple regression analysis. The results indicating that customer record keeping, suspicious transaction reporting, and employee training have a significant relationship on money laundering prevention. Money laundering activities could be curbed by concentrating on customer record keeping, suspicious transaction reporting, and employee training. The findings show how the Anti-Money Laundering, Anti-Terrorism Financing and Proceeds of Unlawful Activities Act 2001 (AMLATFPUAA) has become a vital gap in combating money laundering. Similar research may be performed in other environments with different money laundering laws and regulations.
