The Dutch Central Bank published a podcast episode explaining how banks, prosecutors and supervisors tackle money laundering, focusing on the role of financial institutions in detecting suspicious activity and the need for proportionate anti-money laundering controls. In the episode, DNB staff discuss how money laundering often uses complex and hard-to-detect structures rather than only visible cash movements. The discussion sets out that banks and other financial institutions are expected to report indications of money laundering to the Financial Intelligence Unit, after which police and the Public Prosecution Service conduct further investigation. DNB also reiterates that firms' measures should be proportionate to risk, with less intensive checks where money laundering risks are low and stronger controls where risks are higher. The episode also covers the use of underground banking to move illicit cash internationally and includes a segment on the importance of KYC officers in banks.
