The term 'money laundering is now a commonplace word. The lures of illicit business profits, corruption among high officials, the attraction of higher profits, and weaker regulations in LDC are all responsible for the parallel economy to grow. Many agencies are working to target "suspicious financial transactions". The biggest name is Financial Action Task Force (FATF), the intergovernmental group however even in their 2022 list the biggest infamous names are missing. The 28 countries include counties from Asia, Africa, Europe, Americas-the globe!. Noteworthy to mention that the US scores only around 5.03 on their overall risk score is which is not that good with all the checks and balances the US boasts about. One still remembers some of the renounced banks to fall foul of anti-money laundering crimes including the US were - HSBC , Wachovia Bank , Standard Chartered Bank, Commerzbank, Westpac Bank. My question is based upon the definition of suspicious transaction under Rule 2(1)(g) of PMLA-2002 if its adequate or needs to be expanded/clarified or to include government-to-government purchases, inter-corporate lending, and most important fictitious transactions found in certain industries to claim tax refunds.
